I've written a small section of code that takes alot longer to complete than I think it should. The code is actually using a Graphics object but I put this post in the General forum as I believe the bottleneck has nothing todo with the actuall drawing. The following code takes approximately 480ms to complete (whereas simply drawing the equivalent number of rectangles takes about 9ms). foreach(Square sqTemp in arrGrid) { if(sqTemp.Type == SquareType.Node) gBuffer.FillRectangle(Brushes.Black, sqTemp.Bounds); else if(sqTemp.Type == SquareType.Link) { if(sqTemp.Link == LinkType.Yes) { gBuffer.FillRectangle(Brushes.Black, sqTemp.Bounds); } else if(sqTemp.Link ==…

Hello all, Out of nowhere i've been asked to write a small exe to distribute to our clients that will install some template files onto there computers. (Yes i've raised the issue of client's willingness to run foreign exe's on there computers). Now back in my uni days i remember hearing someone mention that you could compile a file(s) into an exe and then access them @ run time. Now I assume(???) that when compiling in .NET you set the Build Action to embedded resource to compile a file into your exe... but how do you then access this file? Many Thanks

Haven't had much of an opportunity to work with web services, so I'm venturing out and trying to get up to date. VS makes it so easy...not much of a learning curve at this point. Question though - returning primitives or class thas that can be serialized (DataSet) is simple enough, what if you want to return a file of some sort; like a picture, or a word document? I'm very curious about this part. Also - anyone who has some beginner articles on how to get things into this directory that's out there floating somewhere - or do people even use that? Seems like Amazon, Google, and Yahoo weren't in it - but you go to there respective development sites and you can find i…

Interfaces are a sort of contract which states that the implementing object must implement all methods of the interface. Fine. But at the next level up you might have several related interfaces, and want to have a contract that a dll will implement all of those interfaces, and do so just once. Can this be done? Or am I better thinking of having one big interface and somehow dividing the procedures in that into categories?

From documentation: � Implicitly typed local variables, which permit the type of local variables to be inferred from the expressions used to initialize them var i = 5; var s = "Hello"; var d = 1.0; var numbers = new int[] {1, 2, 3}; var orders = new Dictionary<int,Order>(); Is it me or does this take maintainability way down (especially when you through in a few 10's to 100's line of other code - what was s again? Now we get back to declaring objects: strUser; intID; objWorkflow decAmount; Yeah - it's a pain enough to deal with in JavaScript - I don't really want to have to support this in compiled code too! Readability goes threw the floor, …

ok I have never messed with GetPixel before so this is my guess at how it supposed to work (I got really close i think) My code: Public Class Form1 Public Declare Function GetPixel Lib "gdi32" Alias "GetPixel" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long) As Long Private Declare Function GetForegroundWindow Lib "user32" () As Integer Private Declare Function GetWindowDC Lib "user32" (ByVal hwnd As Integer) As Integer Public Declare Function ReleaseDC Lib "user32" (ByVal hWnd As Integer, ByVal ByValhdc As Integer) As Integer Private Sub GetPixels(ByVal hdc As Long, ByVal x As Long, ByVal y As Long) Dim black As Color = Color.Black Di…

I have a VB6 application that writes a 2 dimensional array (40,1024) to a file using FileNum2=freefile Open FilePath For Binary As #FileNum2 Put #FileNum2, , VoltArr Close #FileNum2 Where VoltArr is a 40 x 1024 array of double type. I know need to open that file using .NET 2003. I need to load the entire array at once just like I did in VB6 using Dim FileNum As Integer FileNum = FreeFile Open FName For Binary As #FileNum Get #FileNum, , ImageArr 'Populate array Close #FileNum Can someone point me in the right direction?

I have a list of button names that exist on my form in my DB, I have added the functionallity for the admin user to determine what buttons they wish to see i.e. the DB has column for the name and another column specifying true or false. What I would like to be able to do is build the VB code up form the DB. An example code (not correct just to give you an idea) Do While myReader.Read ' get button name from DB dim buttonName as string = myReader("columnName") ' get button is visible (true or false) from DB dim buttonVis as boolean = myReader("columnVis") ' This is where I want to dynamically build the vb code using the above ' values me.button…

The .Net framework has a class, System.Windows.Forms.NativeWindow, which provides low-level encapsulation for a window. I would like to use the class to override a window's WndProc function. I would need to inherit the class in order to override the protected method WndProc(). The problem is that I need to use this class for a pre-existing window from another program, which means that I can not use the constructor, but instead I need to use the NativeWindow.FromHandle method, which will not return my inherited class, but rather a NativeWindow, hence my override will not be used. There is a function AssignHandle, but I used this function and my WndProc is not being called…
