• ti_m Newbie with uninstall and update questions

  Hello, I am a complete newbie when it comes to VB and VB Express Edition. My issue with my app is twofold: 1.) when uninstalling the app, only the start menu shortcuts are removed.

I have tried several variations on the RegKey value and none work: SOFTWARE\Apple Computer, Inc.\iTunes "SOFTWARE\Apple Computer, Inc.\iTunes" SOFTWARE\Apple Comp ...Show All

Any Ideas why im getting behaviour Thanks Yes, I have a sdf file in the data folder inside the application folder, but I'm still getting the same problem.

• Jeremiah Morrill Possible to apply column style to ListView control?

  Is it possible to apply column style to the ListView control  If you have something like the  DefaultCellStyle as in the DataGridView control.

So please don't comment in the forum if you only have rubbish to add. Yes, no su ...Show All
