This will not give the current directory. This will give the full path of the executable which is not same as the current directory

He did not ask for the current directory, he wanted to know where his application starts (runs), and that is what I answered to.

this is how i do it:

// set the current working path to m_strWorkingPath
char curdir[_MAX_PATH]; 
if( _getcwd( curdir, _MAX_PATH ) == NULL )
{	AfxMessageBox("Unable to determine the current working directory");
	bInitSuccessful = FALSE;	}
m_strWorkingPath = (CString)curdir + "\\";

is GetModuleFileName() a better method?

i notice it returns the full path and executable..

GetModuleFileName can be used to retrieve the path of the running application, whereas _getcwd (and GetCurrentDirectory) can be used to retrieve the current directory.
The current working directory need _not_ be the same as the location of the running application.

Once you have the path of the running application, you can use _splitpath() and related functions.

wow, a function like this does exist there. What I did is:

TCHAR szBuff[_MAX_PATH];
::GetModuleFileName(AfxGetInstanceHandle(), szBuff, _MAX_PATH);
char ch = '\\';
char * pdest = strrchr(szBuff, ch);

to extract the application name from its full path.

Many classes added in addition to revious classes. Also new language named C# is availabe too.This language completely based on .NET framework.

I think in most case yes but not all of them.

Why should it be impossible to compile some VC++6 projects in VC++.NET??

noo... thats not true... but if you compile VC++.NET projects in VC++6 you can get problems because there is some difference between MFC7 and that MFC that VC++6 has (MFC4 or what it is)!

Hello,

Does MFC provide us with a check list control.

If not, how can I do it?

I need to build multi columns list with a check box at the left.

Thanks,

With Best Regards,
Rula Ghabbiesh.

if u mean the Kist box related stuff
just change the list control in to the Report view and set the extended style Like

yourcontrol.SetExtendedStyle(yourcontrol.GetExtendedStyle()|LVS_EX_CHECKBOXES );

Yes , you can! Internally there are two buffers, one for reading and one for writing.

Hi everybody,

I'm using a function taken from a DLL.

It can be a lengthy wait for it to finish so I want to create a stop button to stop the function if the function begins to take too long. As the function is in the dll, I don't know how to stop the function.

Could anyone help me in teaching me how to do this? Thanks!
