OK, i'm trying to make a test app. So far, I've been able to make a window, but it flashes on the screen for a second then disappears. I am using the command for Show Window, but it still flashes for a split second. Any help with that?

Also, I am trying to make a dialog box pop and get user input to add to a file. I guess I should make a new window, then have a child window to that as an EDIT window? (The site i'm looking on is http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI/WindowsUserInterface/Windowing/Windows.asp ) How would I get the text that user placed in the EDIT box?

Sorry if my post is confusing, I feel really sick now...

Code has been attached. Some of this stuff is new to me so... im sort of lost. But I guess practice draws you closer to perfection.

But I wonder, hmm...

My window has the default Minimize, Maximize, and Close buttons. Would I need to set something so when the "X" button is clicked the program terminates? Or does it do this automatically?

You dont have the main processing loop - no wonder the window only stays up for a split second.

What do you expect to happen when the program ends?

Your example is exactly like having a program 'MAKE OBJECT CUBE 1, 1' and wondering why DBPro just flashes up and disappears.

I feel extremely stupid

Thank you for your help, and thanks for the link IanM.

Err... don't exactly know what you mean. I just used a source code example on MSDN, so anything it did, I did.

Don't worry, I'm just pushing you ahead too far lol. Basically the WndProc() function is used to check messages and do things based on them, essentially your window won't react to input until you create that funciton. But like I said, don't worry about it until you get up to it.

Can anyone see a problem with this Winsock code (I'm making a server). It says wsaData hasn't cannot be switched from and unsigned int to a signed int. I followed the instructions from MSDN, so I don't know whats wrong....

NOTE: This is only an excerpt from my entire Server CPP file. Theres a lot more to it than what I am showing here

Have you tried :

erpt = WSAStartup(sockversion, (WSADATA *) &wsaData);

EDIT: OK, I toyed around with it, now my code is:
erpt = WSAStartup(sockversion, ( *WSADATA ) &wsaData);

and I'm only getting one error, which is:
server.cpp: In function `int WinMain(HINSTANCE__*, HINSTANCE__*, CHAR*, int)':
server.cpp:18: error: syntax error before `)' token
