Thanks you very much for your help, it was easyer than I thought, with the rejilla array I can generate one event for all the cuadraditos and cast the sender to get it state and the adjacent states... thans again.. for(int i=0;i<ms.Y;i++){ for(int j=0;j<ms.X;j++){ rejilla[i,j]=new Cuadradito(i,j,ms.Tipo(i,j)); this.Controls.Add(rejilla[i,j]); rejilla[i,j].MouseUp +=new MouseEventHandler(rejilla_MouseUp); } } Bye, RonQ.

Hello, I'm learning and I want to know the best way of doing this. I have a NxM square of inherited pictureboxes dinamically created: //in the form public frmMain(){ for(int i=0;i<N;i++){ for(int j=0;j<M;j++){ this.Controls.Add(new Cuadradito(i,j,number)); } } } //the point class public class Cuadradito:PictureBox{ public Cuadradito(int xCoord, int yCoord, int num){ state=num; } private void Cuadradito_MouseDown(object sender, MouseEventArgs e) { state=some_value; } } The number passed is the state of this point. In the MouseDown event I change the state of this point and I need to change the states of the adjacent points. Mi question is how can I do this. I have the N and M values of the points I need to change the state but the MouseDown event occurs only in the instance of "Cuadradito" clicked, so how do I tell the rest of the points to change states. I mean, there is no comunication between instances of this class. I can add an event, but I don't know if this is the best way to do it (an event that fires after the MouseDown, like ChangeState). Thanks, hope you can help. RonQ.

Hello, I've made a control (two textboxes in a table), now I want to inherit that control and create two new controls adding to those textboxes a listbox in one case and a checkbox in another, for example. But when I inherit the control I can't see the original design, I can access the controls in the base class but only by code, I can't see them, and if I compile and show the child control in a page, the base control doesn't apear, I get an empty page (since the child control is empty). What I'm doing wrong? Thanks, Ronq.

I found one, is just what I need, is not as great as the dotnetcharting, but is really good and complete... and completely free!! http://www.carlosag.net/Tools/WebChart/Default.aspx bye, Ronq.

Thanks for the link, but I need one that is completely free, the free version of this component adds an logo and a link to the page. I don't need one as good as this, just siple 2d columns and pie charts. If anyone knows... Thanks, Ronq.

Hello, is there any free charting class or component. I need to make some financial charts, and doing it by hand with GDI+ could be too much work, maybe somebody has done this before and can help me. There are a few commercial components but I'm looking for a free one. Thank you. Ronq.

Is doing that (using the API) unmanaged code?

Hello, Can anyone explain what is p/invoke? or give a link or anything.... Thank you, Ronq.

Thank you very much... that code is great, that's exactly what i needed.... two months ago... :p just kiding. I can still use it! Thanks again.. Bye, Ronq.

thanks for your answer, but... I can't find Interop.Scripting.dll, is a file or a namespace, can you tell me the full namespace/file name?? Bye, Ronq.

Did you duplicated also the "Undo" function?? can you send me that code? Bye, Ronq.

Hello, simple question... How do I get the free space of a drive, example "c:" 2GB, "d:" 130 Mb... etc. Thanks, Ronq.

I copyed the your code and it worked great, I think your problem is that you have to create a C# Console Aplication, that's what I did, or you can change the project type in the solution explorer in the project properties. I also made a new file example.cs with that code and then I copiled it with the command line "csc example.cs" and it worked great too. Try some of this and tell me.. Bye, Ronq.

I have this class that inherits an ArrayList, and I want to add a Filter Function, I want the method to return the same object (the inherited arraylist) with only some of the items depending on the value of property in the contained object that will be passed as a parameter, and I want the returned items to be the actual items of the arraylist, not a copy of them. How could this be implemented? It's something like the Filter function in the datasource object. This is my class: Public Class cLineaArrayList Inherits ArrayList Default Public Shadows Property item(ByVal Index As Integer) As cLinea Get Return DirectCast(MyBase.Item(Index), cLinea) End Get Set(ByVal Value As cLinea) MyBase.Item(Index) = Value End Set End Property Public Shadows Sub Add(ByVal Value As cLinea) MyBase.Add(Value) End Sub 'This is the function I want to create, but I don't know how to do.. Public Function Filter(FilterIndex As Integer) as cLineaArrayList 'I should have to scan all items and copy them, how? End Function End Class Thanks, Ronq.

About the functionality of the program it will have to be hard coded, the servers doesn't give you any functionality, they only send and receive messages (network TCP/IP packets), each one in their own protocol, you will have to create the different functions like "sendIM" for each server, the same with login, chats, etc... It's an arduous task to do what you want.
