perhaps you could search google for some C++ tutorials, there are many tutorials available for both beginners and professionals, ranging from creating a simple text editor to reprogramming your mothers hairdryer.

This one here[^] covers most of the basics.

File name from a command line

Hello all.

Let's assume I have commands like this:
"c:\Program Files\Product\command.exe" -arg1 -arg2
\\.\c:\Program Files\Product\command.exe -a 1

I would like to know how to extract the "command.exe" part from whatever possible command syntax Windows allows.

Thanks all.

Wont argv[0] give you the exe name .

int main(int argc, char* argv[])<br />
{<br />
	char *exeName = argv[0];<br />
       // to  hold the filename <br />
        TCHAR szFileName[_MAX_PATH];<br />
	_tsplitpath( exeName , NULL, NULL, szFileName, NULL );<br />
	return 0;<br />
}

// after seeing michael answer it striked me you were looking for the exe name

If you have the params separated already (such as, in the argv[] array) then call PathFindFileName()

Hi all,

have any of you had any experience coding debbuger traps? You know those pices of code which detect if somebody is trying to reverse engineer your app. I you have any code samples or links to useful websites dealing with this I would be very much appreciative.

Thanks in advance.

I have a library in a file libgsl.a, which I want to make use of in my .dll that I write in VC++. How can I actually force compiler to link it? I tried adding the path to additional library path, but I still get the "unresolved external symbol" error...

.a is a Unix format, you'll need to recompile the code with VC for VC to use it.

Try to use #pragma directives

The following pragma causes the linker to search for the Test.Lib library while linking. The linker searches first in the current working directory and then in the path specified in the LIB environment variable.

#pragma comment( lib, "Test" )

Hi.

I dynamic append some item in a popup menu
AppendMenu(hMenu, MF_STRING | MF_ENABLED, 1000, "111");

Yes by default all these handlers are disabled unless you activate it through the command_UI handler .check enablemenuitem.
// try insertmenu or insertmenuitem

How to disable the close icon in the title bar of an MFC Dialog after dialog creation?

Hello,

In addition to catching the WM_CLOSE event, I would like to disable the close icon on the dialog title bar when some critical section is being parsed in my application.

Is this possible?,

For those that use Nero Burning Room, when you are burning a CD/DVD, the close icon on the dialog title bar is dissabled.. How can be this done under MFC?

http://img82.imageshack.us/img82/1588/disableclose7uy.gif[^]

I guess that the style of the window is changed with SetWindowLong(), but I don't manage to find how.

Thanks in advance.
