How to read command line parameters

[gmlnd]

I have a CFormView based project that cleans out the system. For example, it deletes cookies, and temp files. When I run the program, the user can select checkboxes and click on a button to wash. Is there any way to adjust the program so when the user clicks the .exe file, my program reads the command and does the wash automatically without opening the actual program?

You can store parameters for program in INI file, in Registry, or even read them for command line - see XGetopt for an example of reading command line. azi_games wrote: without opening the actual program I do not understand what you mean. If the user clicks on a program, he expects to see something happen. If nothing happens, he will probably click again. After three or four times, he will probably think your progam doesn't work, and will delete it from system. Of course, if this is really what you want to do, then there are ways to make a program invisible - e.g., on NT, make it a service. Or make your program's main window the child of an invisible window - it will not even show in the taskbar. Best wishes, Hans

I mean that the program does something without opening up the window. I have found some information about this but it still is not clear to me. BOOL CMyApp::InitInstance() { LPSTR lpszCmd=GetCommandLine(); // parse lpszCmd if(command_line_keys_detected) { // do all your tasks here return FALSE; } // // original body of InitInstance // goes here // } I'm getting command_line_keys_detected error: undeclared identifier. I don't know how this is supposed to be declared. Thanks.

It's a variable. It needs to be declared just like any other.
