Using ShellExecute to launch notepad ???
-
I've snagged this to open a helpfile for an MFC dialog. For now, it's OK to be just a text file, though at some point an integrated help file / CHM might be better ShellExecute(this->m_hWnd,"open","notepad.exe","PTW Geske Analyse Help.txt","",SW_SHOW ); Problem is, I am not sure what the paths are involved. It opens notepad correctly but it is not finding the text file. I tried putting it in the same folder as the executable that's launching notepad but to no avail. How can I use a relative path so that if I distribute the program exe and the help file and state that they should be in the same folder, then notepad will correctly find the text file t.i.a Lee ps have seen ShellExecuteEx but it seemed the extra info (incl. path) refers to the path for notepad and not the target file PS it seems to be defaulting to desktop since thats where it saves a new file if promptedm and when I put the txt file there it does indeed open it. Perhaps I need a SetPath type instruction, but I want it to be relative to the running program and not a hard coded path.

Maybe check out the GetModuleFileName() API and build your full pathname from there... Mark

change to this :
::ShellExecute(NULL, _T("open"), _T("notepad.exe"), _T("PTW Geske Analyse Help.txt"),
**NULL**, SW_SHOW);it should whork, unless the PTW Geske Analyse Help.txt file is not found in the application or system path... but you can provide its full path name

Thanks. This is the kind of thing I keep asking about - which books will teach me how to do things the proper way. I know the _T is a unicode thing isn't it? and the :: is some kind of namespace item, so where can I get a thorough and proper grounding in "good" MFC/C++ from start to finish
