ShellExecute()
-
I'm sorry for the generalization, but I need help using the ShellExecute() function (to launch a .hlp file). ShellExecute( ?, "open", "Helpfile.hlp", NULL, ?, //dir SW_SHOW ); I put a '?' where I don't know what I should put :) The first is the window handle thingy, I really don't want the opened file attached to anything, how do i do this? The second ? is the directory... I have no idea what to set this too. If it's the programs current dir, how do i find that? Thanks

It works just fine! briefcase wrote: The second ? is the directory... I have no idea what to set this too. If it's the programs current dir, how do i find that? Simply put NULL there too! Those aren't necessary when you do such a thing that you do! :) Rickard Andersson@Suza Computing C# and C++ programmer from SWEDEN!

hmm... alright, what am i doing wrong? ShellExecute( NULL, "open", "myhelp.hlp", NULL, NULL, //dir SW_SHOW ); myhelp.hlp exists in the same dir as the calling program.

HWND(0) for the first argument - then any windows are parented by the desktop NULL is usually fine for the directory parameter - it's the 'default directory' (i.e. if you were at the command prompt, it's what would be listed if you did 'dir .'), which is usually not needed if you've specified an absolute path (i.e. drive:\path...\filename.extension or \\server\path...\filename.extension for the file parameter). To get the current directory (if you need to), use the
