I have created a new button with CreateWindow() and option WS_VISIBLE | WS_CHILD.
How can I modify these options later in the code ? Is it possible?
For example, How can I tell the button that it is WS_OVERLAPPEDWINDOW now?

You want a button with WS_OVERLAPPED (title bar and border), WS_CAPTION, WS_SYSMENU,
WS_THICKFRAME, WS_MINIMIZEBOX, and WS_MAXIMIZEBOX styles?

Check out the SetWindowLong()/SetWindowLongPtr() APIs.

I will look for them, thanks.
If you have a short example , it would be great.

LONG lCurrentStyle = ::SetWindowLong(hwnd, GWL_STYLE);
lCurrentStyle |= WS_OVERLAPPEDWINDOW;
::SetWindowLong(hwnd, GWL_STYLE, lCurrentStyle);

Check out the docs for SetWindowLong(). You may need to call SetWindowPos() or other API
after setting certain styles.

Thank you for help!
I understand how it works now. And it works well Smile | :)

Problem solved.

You can use ModifyStyle, too.
ModifyStyle(0,WS_OVERLAPPEDWINDOW );

It looks like what I was searching for, but... I can't find it.
I'm not using MFC, CView Cstatic etc...

I'm using "windows.h" with HWND etc...

Where can I find this method or something similar ?

You need to use SetWindowLong then.
e.g. If you want to add WS_CHILD style to a window you can do like this,

SetWindowLong(hWnd,GWL_STYLE,WS_CHILD);

I would like to see source code of header files and pragmas used in my source, when I compile in Visual Studio 6. I wanna see complete source code. Intermediate files?
It's possible?

Sorry by my English.

Thx!

ok, I get it.

I'm not certain you can do it from WITHIN VC6, or if the command line CL.exe ( or whatever it's called ) can do this.

with G++ ( gnu/linux compiler ) you can call the compiler with the -E switch to preprocess the file.

The keyword here is preprocess, this will "expand all the headers, #defines and other stuff.

for your information this can create a BIG file.

I created the following program :

#include <iostream>

int main()
{
  std::cout << "tata";

  return 1;
}

and generated the preprocessed file and the file is 600+ K. ( 24000 lines )

have a look at the CL.exe documentation on MSDN to see if there's a switch to preprocess the file.

Assign a file type to my program

Hi,

I have my own file format and a program loading those files.

Under Windows XP i got the automatic file asssignment working, but it doesn't work under windows Vista. So i think i didn't do it correctly under XP, maybe it only works there by accident Wink | ;)

.

Do you guys know how to automatically assign (what to write into registry) a file format to a program (which also works under Windows Vista)?

Here is how i do it:

<br />
void RegisterFileType(const String& extension,<br />
					  const String& fileRegisterName,<br />
					  const String& fileExplorerName)<br />
{<br />
	// get applications path<br />
	TCHAR buffer[1024];<br />
	GetModuleFileName(NULL, buffer, 1024);<br />
	CString applicationFileName = buffer;<br />
<br />
	// register file extension<br />
	CRegistry keyFileExtension;<br />
	keyFileExtension.CreateKey(HKEY_CLASSES_ROOT, extension.AsChar());<br />
	CString standard = _T(fileRegisterName.AsChar());<br />
	keyFileExtension.SetValue("", standard);<br />
	keyFileExtension.CloseKey();<br />
<br />
	// set name which appears in the explorer<br />
	CRegistry LMFile;<br />
	CString fileName = _T(fileExplorerName.AsChar());<br />
	LMFile.CreateKey(HKEY_CLASSES_ROOT, standard);<br />
	LMFile.SetValue("", fileName);<br />
	LMFile.CloseKey();<br />
<br />
	// set the default icon for the files<br />
	CRegistry keyDefaultIcon;<br />
	CString defaultIcon = standard;<br />
	defaultIcon += "\\DefaultIcon";<br />
	keyDefaultIcon.CreateKey(HKEY_CLASSES_ROOT, defaultIcon);<br />
	CString iconPath = applicationFileName + ", 0";<br />
	keyDefaultIcon.SetValue("", iconPath);<br />
	keyDefaultIcon.CloseKey();<br />
<br />
	// prepare shell<br />
	CRegistry shell;<br />
	CString shellPath = standard;<br />
	shellPath += "\\shell";<br />
	shell.CreateKey(HKEY_CLASSES_ROOT, shellPath);<br />
	shell.CloseKey();<br />
<br />
	CRegistry open;<br />
	CString openPath = standard;<br />
	openPath += "\\shell\\open";<br />
	open.CreateKey(HKEY_CLASSES_ROOT, openPath);<br />
	open.CloseKey();<br />
<br />
	// create open command<br />
	CRegistry command;<br />
	CString commandPath = standard;<br />
	commandPath += "\\shell\\open\\command";<br />
	command.CreateKey(HKEY_CLASSES_ROOT, commandPath);<br />
	CString a = "\"";<br />
	CString cs = a + applicationFileName + a + CString(" ") + a + CString("%1") + a;<br />
	command.SetValue("", cs);<br />
	command.CloseKey();<br />
}<br />

Do i miss anything? Or do i do something incorrectly?

Hope you guys can help me!

Thanks a lot in advance and i hope to hear from you soon.
