VS 2005 has a new control called "TableLayoutPanel". You may want to try this before writing your own rectangles. The panel certainly supports click events. Check this CP article[^].

Hi all,
Right now, I'm struggling with finding a solid way to determine what sort of string the user has input. The strings I want to support are URLs, paths to files, or network paths. I've tried playing with the UriBuilder class and just building my own string "URI" (properly formatted so the URI class doesn't throw an exception).
Does anyone have any ideas? Pointers on where to look? I know that URIs can do most of this, but it doesn't seem to like network paths and is pretty prone to exceptions.
Thanks in advance!

What does the byte array contain?
a) The full bitmap with headers and pixel data: Write in into a MemoryStream and create an Image with Image.FromStream().
b) Only the pixel data: Copy the array into unmanaged memory, create new Bitmap with the expected width, height and PixelFormat, lock all bits and set Scan0 to the first element of the unmanaged array. Go on, just copy the code from this FAQ^.

Hello. For a project i am currently working on, i need to be able to send data, images specificly, between computers using sockets. Unfortunately, i have had some diffuculty making tcp transfer the data. I've been trying to use NetworkStream.read() and NetworkStream.write(), but for some reason the image always gets messed up in transfer. I tried sending the data in 32 byte bursts, but the image still arrives with serious errors in it. What is the fastest and most reliable way to send byte arrays across computers, preferably with streams?
P.S.
a few lines of code would be extremely helpful

Search CP for "tcp" filtered by C# and you'll get tons of artciles.

Hello
I've already been sending images across LAN networks using sockets, but strangely I didn't face your problem!!
Your post raises some points:
1- Try checking your method of sending data. Do you send other data than images? Are there any problems in any of the other types?
2-Are you sure you are reading the bytes of the image corectly? Try after reading the data, and just before sending it using the NetworkStream, try to convert it back to Image, see if it works.
3- I have been converting my data from Bytes to strings using Encoding.Default.GetString() method before sending them across the NetworkStream, maybe you would like to try this
4- If you still having problems try to use the Socket.Send() and Socket.Reveive() methods instead?? perhaps??
I hope this was helpful.

I am using a DataGrid control (from SyncFusion) and want to allow users to
(1) copy cells from one part of the grid and paste it to another part of grid
(2) copy cells from an Excel and paste it on the grid
I am kinda new to gui development and have to maintain this code. I'll appreciate your help.
Thanks

I have made an application in C# that uses a lot of PInvokes to the Win32 that create shared memory using VirtualAllocEx and more. I have a pretty bad memory leak now. Surprise! I have no experience dealing with this problem. What is the best way to find memory leaks in NET? Or do i simply try random things and cross my fingers?

If you're using native calls to allocate memory, you need to use the same to deallocate it as well.

Hallo,
I saw that ddraw was removed in dx9, so we must use d3d to create 2d-games/graph.
Ok, I read about textures and sprite.draw2d etc.
The problem is:
I use, for test, mspaint to draw the sprite (bitmap 256 colors) with white as a background color.
I didn't understand how telle to d3d to remove the background and draw only the sprite, say a red man on white background: how can I draw only the man without the white background??? Using alpha color for black: Color.FromArgb(0xff,Color.White).ToArgb(); d3d draw the white color as a black opaque and no trnasparent, so the sprite background cover the scene-color.
In simpler words when I draw the sprite in a device cleared with color blue the result is: the device totally blue and in the middle a black rectangle with the red man inside.
Hope I explained right 
Thank you

Map the network drive. Add the code to copy the file from a local drive to the mapped network drive.

how can i make my project(csharp) a service on window....which automatically starts running as the system sarts

Follow these steps:
1) Create a Windows Service project.
2) Installe the service you build. The code generated will tell you which command line to install/uninstall the service.
3) Configure it to automatical start using MMC or any other control tool.
Best,
Jun

File/New -> Project. Find the Windows Service project...
You'll probably have to start converting your code to run on a seperate thread. Windows Services normally create a seperate thread to run their code on. Do NOT just put your code in the OnStart event. You'll get some interesting errors and behaviors if you do.

Hi all,
I have a form (we'll call form A) which I need to hide because it takes 4 seconds to load. I have created another splash screen form (Form B) to cover form A and hide it while it is taking it's sweet time being created. I have to create Form B modeless so Form A can continue to initialize. Once Form A is finished I cannot figure out a way to return focus back to Form B which is covering Form A.
Any suggestions???
BTW: This is a continuation of the OPACITY nightmare from yesterday!
