Getting file extension from path

This is hopefully a basic question but it's been a VERY long time since I used C++ and I just need to know how I can get a file extension from a path and compare to constant extension.

I have an input:

LPCWSTR pwszPath

and a constant:

WCHAR MY_EXT[4] = L".me";

I need to know if pwszPath ends with MY_EXT but I can't think how to do it..

Any help would be great!

Use PathFindExtension.

Matching extension will somewhat look like this...

// Assumption: there is no '.' in extension
bool MatchExtension( LPCTSTR lpctszMyPath, LPCTSTR lpctszChkExt )
{
 ASSERT( lpctszMyPath && lpctszChkExt );
 LPCTSTR lpctszExt = PathFindExtension( lpctszMyPath );
 // Or if you don't wish to link to shlwapi for this one function use
 // LPCTSTR lpctszExt = _tcsrchr( lpctszMyPath, _T( '.' ));
 return ( lpctszExt && _tcscmpi( lpctszExt + 1, lpctszChkExt ) == 0 );
}

Play AVI on Status bar

I am working on an existing application in VC 6.0 MFC, there are a few call in the application, which takes a very long time, I am working on placing some progress indication (play avi)on the status bar. Since there are many calls in the applicaion which takes very long, I thought of createing a thread for playing AVI file on the status bar. And the first statement of the time consuming funcions will be call to the progress indication thread. ( I dont want to place the time consuming funcion itself in thread, since there are many, I am looking for a simple solution)

Please comment advantage and disadvantage in following this method, and also suggest/advice me some good approch in doing so

I've seen some well known applications like word, excel, powerpoint ,while printing and saving, take this approach. So should be good enough.

If it's just a random animation then you can maybe call Play else you will have to manually change each frame(Seek) to indicate correct progress.

Here[^] is a sample on how to embed a progress bar in a statusbar. You can easily change the progress bar to CAnimateCtrl. Make sure you handle OnSize to move the animate control based on new parent window's size.

Another way is to sub class CStatusBar and embed these features.

What version of Visual C++ express edition you are using? Fastest way to get it working is by installing the correct version of redistributable on the user's computer.

Microsoft Visual C++ 2005 Redistributable Package (x86)[^]
Microsoft Visual C++ 2008 Redistributable Package (x86)[^]

Okay I just saw your other question and if you are using C++\CLI then you have to install .Net framework on user's computer.

Hi,

Use the following statement in your code :

// url is variable
ShellExecute(NULL, "open", url, NULL, NULL, SW_SHOWNORMAL);

That's a Unicode problem. It's expecting "wide" chars. Try this: L"open"
