What I wanted was moving the focus of my keyboard to another place as soon as the number of charactors in the editbox reaches 3.
And I think what you told me can solve my problem.
Thanks a lot!

Hmm didn't get you.

You can use GradientFill function for this purpose.

To redraw background on size change just handle WM_ERASEBKGND and return TRUE to indicate to the application that you have done the background drawing.

thanks for your Reply.
1.i try in OnSize() used SetWindowRgn(),right? have other idea? my mean is the windows is small and SetWindowRgn it is small round, and the window is big SetWindowRgn it is big round.
2.Some time ago, i tried your method but when the window size change big, the background is confusion, the old background(1) still exist, other area redraw ok.
old size
|--------|-------|
| 1 | |
|--------| |
| |
| background |
|---------------| now size
BTW:i say the window can change the size , mean is the window flags had WS_MAXIMIZEBOX and WS_THICKFRAME
 My english so bad, shame.

Yeah it happens because the visible portion need not be painted again.
Try using CClientDC. This way you can paint the entire region.

Hi,
Use GDI+ to draw the bitmaps.
Make the list box owner drawn.
Create a Graphics object and initialise with the listbox DC.
Create an Image object and using Graphics::DrawImage draw the image in the required cell.
Image and Graphics are GDI+ classes.
Thanks and Regards,

Hi there, Iv wrote a program to transfer files between a cleint and a server,the code works fine for small files but not for large files,im going to post the code wich i hope will help other people trying to do something similar and in hope that i can get some suggestions on how to improve the code iv wrote.
<server>
{
char *buffer;
char sizebuf[20] = "";
long SizeOfFile = 1;
long BytesSent = 0;
std::ifstream file ("C:\\Windows\\Example.exe" std::ios::in | std::ios::binary | std::ios::ate);
if (!file)
{
MessageBox(NULL,"Error Opening File",NULL,MB_OK);
}
SizeOfFile = file.tellg(); //get size of file
file.seekg (0, std::ios::beg);
ltoa(SizeOfFile,sizebuf,10); //put sizeoffile in char buf
send(newsock,sizebuf,strlen(sizebuf),0);//send the size to client
buffer = new char[SizeOfFile];
file.read (buffer,SizeOfFile).eof();
do{
BytesSent = send(newsock,buffer,SizeOfFile,0);
}while(BytesSent < SizeOfFile);
Here i dont know if i should be reading blocks of the file into the buffer in the do while loop or out side of the loop and i dont know how to equally divide the file into "Chunks" to be sent separatly and rebuilt the other side help would be appriciated
<client><mfc>
{
char buffer[20];
long SizeOfFile = 0;
char* recvfilebuf;
recv(Socket,buffer,sizeof(buffer),0); //recv size of file to be d/l
SizeOfFile = atol(buffer);
ZeroMemory(buffer,20);
recvfileBuf = new char[SizeOfFile];
std::fstream file (C:\\Example.exe, std::ios::out | std::ios::binary | std::ios::ate); //Dir of our new .exe
if (!file)
{
MessageBox(NULL,"Error Opening File",MB_OK);
}
do
{
recieved = recv(Socket,recvfileBuf,SizeOfFile,0); //recv actuall file
file.write(recvfileBuf,recieved).eof(); //write new file
}while(recieved < SizeOfFile);
ZeroMemory(buffer,20);
}
I know there is a better way of doing what im trying to do but its hard without extensive know how on the subject..Any comments would be greatly apriciated
Thankyou

 Question : In MDI application, when I open a new document, I want the frame size set by myself rather than the fixed size set by MFC. I wonder where should I implement this, and how?
Thanks

In the view, I would have thought. That's the class responsible for the way the document is represented, so when one is constructed and shown, you'd need to size it.

Hi,
I have created threads using CreateThread (6 parameters) format in vc++ as following
DWORD ThreadId_1,ThreadId_2;
CreateThread(NULL,0,StartThread1,CREATE_SUSPENDED,0,&ThreadId_1);
CreateThread(NULL,0,StartThread2,CREATE_SUSPENDED,0,&ThreadId_2);
where StartThread1 and StartThread2 are the thread functions correspondingly. 'this' refers to my present main application.
I would like to suspend and resume the threads at any point of time, but I didn't understand how to use SuspendThread and ResumeThread functions. I would really appreciate if someone can help me on this (how to suspend, resume and close threads whereever I need) using the above example.
thanks,
-Pav

If you call C-run time functions in any of your thread functions, you should be using beginthreadex instead of CreateThread.
If you are using MFC, you should use AfxBeginThread instead of beginthreadex.
Having said that, use the thread handle to ResumeThread to get it started again. You can check return value to decide if it was supposed to actually resume or not. If the return value is zero, the specified thread was not suspended. If the return value is 1, the specified thread was suspended but was restarted. If the return value is greater than 1, the specified thread is still suspended.
Use the handle to the thread to SuspendThread. Be mindful of this warning:
Calling SuspendThread on a thread that owns a synchronization object, such as a mutex or critical section, can lead to a deadlock if the calling thread tries to obtain a synchronization object owned by a suspended thread. To avoid this situation, a thread within an application that is not a debugger should signal the other thread to suspend itself. The target thread must be designed to watch for this signal and respond appropriately.

Hi Blake,
thanks for ur reply. I am not able to figure out which one is the thread handle, while I am using my thread name ThreadId_1 (assuming its the handle), it is giving syntax error.
Actually in my program I need to make anyone of the threads to be active at any time depending on the user input. So i need to suspend and resume them accordingly. I am not getting the correct syntax on using those functions. Can you gimme some sample syntax code for my example. I am using these threads in my MFC application, but these threads wont handle any windows, but only to do the processing.
I did have another version of my program with AfxBeginThread, but there too I need to know the syntax.
thanks,
-Pav
