i've fond a lot of exemple on how to add my program as a service on these forums, but what I want to do is add another program to service list... I dont even know if it's possible but I ask anyway. I want to write an installer that will install my program + Apache web server, I need apache to run as a service, but I dont want the user to go trough the usual setup, my program should install it automatically... but I dont know how to make it a service anyone can help?

Ok I know this have been answered a couple of time, but all the thread I saw confusded me more than helped me... so i'll strat with an easy question... is usin API the only way to do it? is there a way to do it with managed code? my head hurt from readind all those article :/

I have this error coming up and I dont know what it means or what to do with it: An unhandled exception of type 'System.InvalidOperationException' occurred in system.data.dll Additional information: ExecuteReader requires an open and available Connection. The connection's current state is Open, Fetching. Why would the conection state change to Fetching? and how can I turn it back to normal?

ok, after searching like crazy I fond a way to do it... even if it may not be the best way it's working! first i had to change back my struct to make it use only byte array: [structLayout(LayoutKind.Sequential,Pack=1,CharSet=CharSet.Ansi)] public struct EnteteAvi { [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public byte[] chunkId; public Int32 fileSize; [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public byte[] fileType; [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public byte[] subChunk1ID; public Int32 subChunk1Size; [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public byte[] subChunk1Type; public Int32 cb; public Int32 MicroSecPerFrame; public Int32 MaxBytePerSec; public Int32 PaddingGranularity; public Int32 Flags; public Int32 TotalFrames; public Int32 InitialFrames; public Int32 Streams; public Int32 SuggestedBufferSize; public Int32 Width; public Int32 Height; [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public Int32[] Reserved; } the writing in the strunct still goes well, the only other change is when I compare to what I need, I need to use: if(System.Text.Encoding.ASCII.GetString(entete.chunkId,0,4)!="RIFF") { return false; } and it'S now working, it see my 4 char instead of magically losing the last one

i belive iisreset is the command needed to reset iis in cmd.... so If you know how to call it, you'll be ok(i hope)

You probably have tough about all this but just in case, do you have acess to the network folder? if you need to enter a password and a username to conect to it, under windows you have to redo it everytime. maybe you already tough of this and you are entering a password everytime, but it's not written there so i'm asking anyway... another way to do it would maybe to create a virtual drive to the folder...

sure but it was byvaltstr from the begining, i only tryed with that when you said that... but still I'm missing a char.

i'll give you another code part to show you what i mean [structLayout(LayoutKind.Sequential,CharSet=CharSet.Ansi)] public struct EnteteAvi { [MarshalAs(UnmanagedType.LPStr, SizeConst=4)] public string chunkId; public Int32 fileSize; [MarshalAs(UnmanagedType.LPStr, SizeConst=4)] public string fileType; [MarshalAs(UnmanagedType.LPStr, SizeConst=4)] public string subChunk1ID; public Int32 subChunk1Size; [MarshalAs(UnmanagedType.LPStr, SizeConst=4)] public string subChunk1Type; public Int32 cb; public Int32 MicroSecPerFrame; public Int32 MaxBytePerSec; public Int32 PaddingGranularity; public Int32 Flags; public Int32 TotalFrames; public Int32 InitialFrames; public Int32 Streams; public Int32 SuggestedBufferSize; public Int32 Width; public Int32 Height; [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public Int32[] Reserved; } public bool LireFichier(string nomFichier) { byte[] data=new byte[Marshal.SizeOf(entete)]; GCHandle handle; IntPtr ptr; System.IO.FileStream stream= new System.IO.FileStream(nomFichier,FileMode.OpenOrCreate,FileAccess.ReadWrite,FileShare.None); stream.Read(data,0,data.Length); stream.Close(); handle=GCHandle.Alloc(data,GCHandleType.Pinned); ptr=handle.AddrOfPinnedObject(); entete=(EnteteAvi)Marshal.PtrToStructure(ptr,typeof(EnteteAvi)); handle.Free(); this.nomFichier=nomFichier; if(entete.chunkId!="RIFF") { return false; } if(entete.fileType!="AVI ") { return false; } if(entete.subChunk1ID!="avih") { return false; } return true; } as you see in there, im asking for 4 char in my struct, and I compare with RIFF entete.chunkId is returning "RIF" wich is lacking 1 char!

using LPStr instead of ByValTStr cause the program to an An unhandled exception of type 'System.NullReferenceException' occurred in mscorlib.dll Additional information: Object reference not set to an instance of an object. when the code reach entete=(EnteteAvi)Marshal.PtrToStructure(ptr,typeof(EnteteAvi)); and the StructLayoutAttribute CharSet=CharSet.Ansi didnt change anythig, I still get 4 chars array instead of 5... Now I could probably change the [MarshalAs(UnmanagedType.ByValTStr, SizeConst=5)] and put SizeConst=6 and i'd probably get my 5 chars, but then I would probably lose a byte, that is probably pretty usefull to the struct structure....

I read the header that way: [structLayout(LayoutKind.Sequential)] public struct EnTeteJPG { public ushort SOI; public ushort JFIFMarker; public ushort length; [MarshalAs(UnmanagedType.ByValTStr, SizeConst=5)] public string identifier; [MarshalAs(UnmanagedType.ByValArray, SizeConst=2)] public byte[] version; public byte units; public short Xdensity; public short Ydensity; public byte Xthumbnail;// 0 = no thumbnail public byte Ythumbnail;// 0 = no thumbnail } public bool LireFichier(string nomFichier) { byte[] data=new byte[Marshal.SizeOf(entete)]; GCHandle handle; IntPtr ptr; System.IO.FileStream stream= new System.IO.FileStream(nomFichier,FileMode.OpenOrCreate,FileAccess.ReadWrite,FileShare.None); stream.Read(data,0,data.Length); stream.Close(); handle=GCHandle.Alloc(data,GCHandleType.Pinned); ptr=handle.AddrOfPinnedObject(); entete=(EnTeteJPG)Marshal.PtrToStructure(ptr,typeof(EnTeteJPG)); handle.Free(); this.nomFichier=nomFichier; if(entete.SOI!=0xD8FF) { return false; } if(entete.JFIFMarker!=0xE0FF) { return false; } if(entete.identifier!="JFIF\0") { return false; } return true; }

i got 2 diferent problems, depending on what date im reading, when im reading a short my problem is that the bytes are inversed, the first 2 bytes in the file are FFD8 and when read the give me D8FF, since i read it in a short it gives me 55551 when it should give me 65496... i know this is probably stupid and everyone knew that byte were inversed or something... but how can I compare shorts if there dont have the value they are suposed to.... my second problem is when i read a string... all my strings i read from the file are missing le last char my string is suposed to give me "JFIF\0" and instead i get "JFIF", then I tough it was maybe just because of the null char so I checked elsewere in my code where Im suposed to get the value "RIFF" and get "RIF" instead... anyone can help?

thanks, but just so someone reading this thread dont do mistake, using a short here wont work, because the value of 0xFFD8 =65496 and a shot stop at 32767, so a ushort (unsigned short) need to be used

well it's a structure so everything is just public in it... puting it as a short is a good idea... that's what i'll do. but just for my personal (and others) knowledge, how would you do it?

How do I create a 0 (or null) terminated string in c#? if(entete.identifier!="JFIF") { return 0; } the string "JFIF" is suposed to be a 5 char string in wich the last char is a 0 (or null)

this is pretty simple really... what i need is to compare some byte array obtain from the header of a file, to decimal value (to verify the signature) and unfortunatly, the 4 first byte of a jpg are not chars... they are plain hex value, wich Is why i need to do this, here's what I go so far: if(entete.SOI!=0xFFD8) { return 0; } if(entete.JFIFMarker!=0xFFE0) { return 0; } but the problem is that 0xFFD8 is seen as an integer and entete.SOI is a byte[2] so he wont compare them, so is there a way to: 1-change a byte array into integers 2-change an int into a byte array... 3 something else

Thank you! and sorry for hurting your head like that, but I wanted my message to be as clear as possible and dont have people asking me: can you post this or post that

As I suspected, this code is not working I had to change this: this.nomFichier=nomFichier; FileStream stream=new FileStream(nomfichier,FileMode.Open); BinaryReader reader=new BinaryReader(stream); entete=reader.ReadByte(sizeof(EnTeteJPG)); reader.Close(); stream.Close(); to this: this.nomFichier=nomFichier; FileStream stream=new FileStream(nomFichier,FileMode.Open); BinaryReader reader=new BinaryReader(stream); entete=reader.ReadByte(Marshal.SizeOf(EnteteAVI)); reader.Close(); stream.Close(); because he didnt seem to like me useing SizeOf, the compilator was saying to use Unsafe or marshal.SizeOF so i chosed Marshal.SizeOf, but now, it tells me the the Marshal.SizeOf is expecting an object and not a class, but that's not how it work in c++... the other error I get are this: if(entete.chunkId!=Convert.ToByte("RIFF")) { return 0; } I get the error: C:\Documents and Settings\Nicolas Dufour\Mes documents\Visual Studio Projects\ZoneMedia\AVI.cs(27): Operator '!=' cannot be applied to operands of type 'byte[]' and 'byte' so as I suspected, he dont see an array of byte as chars... so I dont really know how to handle this here... please anyone can help?

Thank! it's what was missing. now i just have to make that code work... ^^

is there a way to do this? because I am trying to read the header of a swf file and there is a part in it that is never the same length in bits. it use the RECT data format RECT Field Type Comment Nbits: UB[5] //Bits in each rect value field Xmin: SB[Nbits] //x minimum position for rect Xmax: SB[Nbits]// x maximum position for rect Ymin: SB[Nbits] //y minimum position for rect Ymax: SB[Nbits]// y maximum position for rect this come from the macromedia website: http://download.macromedia.com/pub/flash/flash_file_format_specification.pdf since it use a number of bit, I cant just take the byte, and what is worst is that the number of bits varie for the last 4 data depending on the first value, so is ther anyway to use the reader to read 5 bits, then read xbits(the number in the previous reader)4 time or is there any workaround?

I have a C++ code that do this(write from a file directly to memory) it reads a wave file and store it in memory so it can be changed... here's my Wave.h file: struct EnteteWave { char chunkID [4]; int chunkSize; char format [4]; char subchunk1ID [4]; int subchunk1Size; short audioFormat; short numChannels; int sampleRate; int byteRate; short blockAlign; short bitsPerSample; char subchunk2ID [4]; int subchunk2Size; }; class FichierWave { public: FichierWave(); ~FichierWave(); int LireFichier(char *nomFic); int EcrireFichier(char *nomFic); double CalculerDuree(); short GetNbCanaux();//number of chanel int GetFreqEch(); short GetNbBitsPerEch(); int GetByteRate(); short *donneeG;//left channel data short *donneeD;//right chanel data private: EnteteWave *entete; int nbSamples; char *nomFichier; }; I reand from the file and write to memory using this code: int FichierWave::LireFichier(char *nomFic) { nomFichier = nomFic; FILE *fp; fp = fopen(nomFichier, "rb"); if (! fp) return 1; int validation = fread(entete, sizeof(EnteteWave), 1, fp); if (validation != 1) return 2; if (strncmp(entete->chunkID,"RIFF", 4) != 0) { fclose(fp); return 3; } if (strncmp(entete->format, "WAVE", 4) != 0) { fclose(fp); return 4; } if (strncmp(entete->subchunk1ID, "fmt ", 3) != 0) { fclose(fp); return 5; } if (entete->audioFormat != 1) { fclose(fp); return 6; } if (strncmp(entete->subchunk2ID, "data",4) != 0) { fclose(fp); return 7; } if (entete->subchunk2Size <= 0) { fclose(fp); return 8; } ... ... I tryed to code something similar in C#, but I dont think it'll work because first: to replace char I used byte, but if I say: if(entete.chunkID=="RIFF") will it see the Bytes as an array of char?... here how i trye to do it in c#: ((actually in my c# program I try to read trough all visible media types so here's the exemple of a jpg)) [structLayout(LayoutKind.Sequential)] public struct EnTeteJPG { [MarshalAs(UnmanagedType.ByValArray, SizeConst=2)] public byte[] SOI; [MarshalAs(UnmanagedType.ByValArray, SizeConst=2)] public byte[] JFIFMarker; [MarshalAs(UnmanagedType.ByValArray, SizeConst=2)] public byte[] length; [MarshalAs(UnmanagedType.ByValArray, SizeConst=5)] public byte[] identifier; [MarshalAs(UnmanagedType.ByValArray, SizeConst=2)] public byte[] version; public byte units; [MarshalAs(UnmanagedType.ByValArray, SizeConst=2)] public byte[] Xdensity; [MarshalAs(UnmanagedType.ByValArray, SizeConst=2)] public byte[] Ydensity; public byte Xthumbnail;// 0 = no thumbnail public byte Ythumbnail;// 0 = no thumbnail } I try to write it that way: public int LireFichier(string nomFichier) { this.nomFichier=nomFichier; FileStream stream=new FileStream(nomfichier,FileMode.Open); BinaryReader reader=new BinaryReader(stream); entete=reader.ReadByte(sizeof(EnTeteJPG)); reader.Close(); stream.Close(); if(entete.SOI!=&HFFD8) { return 0; } if(entete.JFIFMarker!=&HFFE0) { return 0; } if(entete.identifier!=&H4A46494600) { return 0; } return 1; } i used various exemple from this site to help me write this code (mainly the marshalling things, which by the way dont work yet....) so I am close to doing this right? I saw that there is a way to use pointers in c#, maybe I could try with that... anyone can help?

I never used marshaling before, but I did some c++ code and I wanted it's equivalence in c#. My code used a struct like this: struct EnteteWave { char chunkID [4]; int chunkSize; char format [4]; char subchunk1ID [4]; int subchunk1Size; short audioFormat; short numChannels; int sampleRate; int byteRate; short blockAlign; short bitsPerSample; char subchunk2ID [4]; int subchunk2Size; }; but in c# we cant fix the array in a declaration on struct. So i searched on these forum and fond how to use marshaling and did this: [structLayout(LayoutKind.Sequential)] public struct EnteteAvi { [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public byte[] chunkId; public Int32 fileSize; [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public byte[] fileType; [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public byte[] subChunk1ID; public Int32 subChunk1Size; [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public byte[] subChunk1Type; public Int32 cb; public Int32 MicroSecPerFrame; public Int32 MaxBytePerSec; public Int32 PaddingGranularity; public Int32 Flags; public Int32 TotalFrames; public Int32 InitialFrames; public Int32 Streams; public Int32 SuggestedBufferSize; public Int32 Width; public Int32 Height; [MarshalAs(UnmanagedType.ByValArray, SizeConst=4)] public Int32[] Reserved; } (it's not the same thing because my c++ code was to acess a wave ane the c# code is acessing an AVI file) I find this Marshaling thing very confused but I think im using it right. the problem is, my compilator does not like it at all.... C:\Documents and Settings\Nicolas Dufour\Mes documents\Visual Studio Projects\ZoneMedia\AVI.cs(30): The type or namespace name 'StructLayout' could not be found (are you missing a using directive or an assembly reference?) Maybe i'm just missing a namespace or using call,m anybody can help? and while you're looking at my code, does it actually look right?

I got powerPoint 2003, and it'S openning, maybe you're using something else than I do. String strTemplate, strPic; strTemplate = "C:\\Documents and Settings\\Nicolas Dufour\\Bureau\\TUJYDKJ.pps"; strPic = "C:\\Documents and Settings\\Nicolas Dufour\\Mes documents\\Mes images\\200162757-001.jpg"; bool bAssistantOn; PowerPoint.Application objApp; PowerPoint.Presentations objPresSet; PowerPoint._Presentation objPres; PowerPoint.Slides objSlides; PowerPoint._Slide objSlide; PowerPoint.TextRange objTextRng; PowerPoint.Shapes objShapes; PowerPoint.Shape objShape; PowerPoint.SlideShowWindows objSSWs; PowerPoint.SlideShowTransition objSST; PowerPoint.SlideShowSettings objSSS; PowerPoint.SlideRange objSldRng; Graph.Chart objChart; //Create a new presentation based on a template. objApp = new PowerPoint.Application(); objApp.Visible = MsoTriState.msoTrue; objPresSet = objApp.Presentations; objPres = objPresSet.Open(strTemplate, MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoTrue); objSlides = objPres.Slides; ... ... ... //Prevent Office Assistant from displaying alert messages: bAssistantOn = objApp.Assistant.On; objApp.Assistant.On = false; ... ... ... //Wait for the slide show to end. objSSWs = objApp.SlideShowWindows; while(objSSWs.Count>=1) { System.Threading.Thread.Sleep(100); } //Reenable Office Assisant, if it was on: if(bAssistantOn) { objApp.Assistant.On = true; objApp.Assistant.Visible = false; } //Close the presentation without saving changes and quit PowerPoint. objPres.Close(); objApp.Quit(); and the program always fail on the objApp.Quit() giving that error: An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in ZoneMedia.exe Additional information: Presentation (unknown member) : Object does not exist. and the powerPoint window stays open.

is there any way to read powerpoint presentation from c#. I dont want powerpoint to open, i want to play the things directly from my program.

i did this recently, but it was in c++ but it should look aproximatively the same in other languages. you've got to use the objet help : Help::ShowHelp() but i dont remember what arguments it need. I thing you need to pass it your helpProvider object. i'll check up later

ok here's my request for now: SELECT tblUser.Nom, tblUser.Prenom, Sum(CréditsDeVente) as somme, tblUser.Societe, tblUser2.Nom, tblUser2.Prenom FROM tblUser, tblIndividus, tblProjet, tblUser as tblUser2 WHERE tblProjet.ProjetIndividu=tblIndividus.NomPrénom AND tblIndividus.IndividuChargéDeCompte=tblUser2.index AND tblIndividus.IndividuRessAffairesEst=tblUser.index AND Statut="Terminé - succès" GROUP BY tblUser.Nom, tblUser.Prenom, tblUser.Societe, tblUser2.Nom, tblUser2.Prenom ORDER BY Sum(CréditsDeVente) DESC, tblUser.Societe, tblUser.Nom, tblUser.Prenom but there is juste a problem, I want the data from the Individus who dont have a ChargéDeCompte in other words, all the data from wich this part: "AND tblIndividus.IndividuChargéDeCompte=tblUser2.index " does not exist. can anyone help me out on there? if you need more info ask... ill put an exemple soon...
