Shell statement usage

Shell statement usage tips 1. Are you anxious to call the system "create shortcuts" Wizard to create shortcuts that VB does not support? Although you can call the fcreateshelllink function in vb5stkit. dll,

But it is designed for the installer. The default path of the shortcut always starts from the current user's "/Start Menu/programs", that is,

If your Windows 95 is attached to drive C, you cannot use the fcreateshelllink function to create a shortcut to drive D. Now, we will introduce you to an extremely convenient and clever Method: Using shell statements to call the system "create shortcuts" Wizard. Create a new project, put a button on the form, double-click this button, and add the following code: private sub commandementclick () open app. path & "/temp. lnk "for output as #1 close #1 'the above two statements create a temporary file shell" rundll32.exe appwiz in the directory where the program is located. CPL, newlinkhere "& App. path & "/temp. lnk "End sub (Note: In a shell statement, newlinkhere is followed by a space. Otherwise, an error occurs .) Run the program and click the command button. How can this problem be solved? The "create shortcut" Wizard appears. If the creation is successful, the shortcut will take

The location of the temporary file temp. lnk. If you cancel the file, the temp. lnk will automatically disappear. Of course,

You can create temp. lnk anywhere on the hard disk. Now you can add a new feature to your program. Enjoy! II. The purpose of rundll32.exe we know that using shell statements can only call executable files, that is, EXE, COM, bat, and PIF files,

What if we want to call other system functions? In this case, the rundll32.exe provided by Windows is ready to use.

DLL, fileprotocolhandler X "(X indicates the file to be run, including the path, the same below .) 3. you can also write it in this way to enable activemovie control: shell "rundll32.exe amovie. OCX, rundll ", 1 and shell" rundll32.exe amovie. OCX, rundll/play X ", 1 will play the media file directly. 4. Shell "rundll32.exe desk. CPL, installscreensaver X", of course, screen protection is installed,

If you write a screen saver, you can write it in the installer, instead of installing it in the system directory.

By the way, isn't VB a self-fishing "application Setup Wizard? Its VB source code is in the installation directory

Put it in "/setupkit/setup1" and study it well. You can make personalized installation programs. 5. Press shift and Right-click a file. The "open mode" option appears in the menu, which may not be a secret. But now,
