Doug This is not a violation of some established standard. Check out http://msdn2.microsoft.com/en-us/library/142dbbz4.aspx for an explanation of why this path is chosen, and what the benefits and drawbacks of using ClickOnce vs. a windows installer package to install your application. Best regards, Johan Stenberg Just out of curiosity, why do you want the application to be located under the Program File ...Show All

• Clinic332050 I'm bored, so does anyone have any ideas on...

  I'm bored with Visual Basic, so I was wondering, what do you people program in VB I'm just bored. I don't know what to do, but I want to use all this programming power. Any ideas Thanks. It happens. Don't force your creativity though. Just take a break or GET A JOB as a developer. You'll never run out of things to code. As you just interact with the world you'll see things you want to automate or find limitations in existing applications you want to extend and overcome. Take some time off of coding and explore other areas of life - love, the arts, literature, or maybe even object-oriented design and solution architectures (related but less domain specific). The world is full of potential applic ...Show All
