• Visual Studio Performance in VS vs. outside it

  I have a pretty small test program using Windows Forms and one unmanaged function. When I run it in release mode inside VS 2005 it takes about 9% CPU. When I run it outside VS, it takes 2% CPU. Why would running inside VS take so much more CPU time Only a profiler can really answer your question. One possibility is that your application produces a lot of debugging events. Example of debugging events: Throwing/catching exceptions Outputting debug strings (traces) Creating/destroying threads Creating/destroying app domains Loading/unloading modules ...Show All

• Visual Basic Can you have a maskedtextbox data entry go from right to left?

  Can you have a maskedtextbox go from right to left I can get a normal textbox to allow data entry right to left but I can not get a masked textbox to work this way. I have a five character database field that I need to be populated in this fashion in order to get a match that I am looking for. ex... when a user types in 3 charcters lets say "222" it will store it that way. I want it to store " 222" notice the to leading blank spaces.

Maybe its something they should fix in future versions, have Enter=Tab as a text box property. ...Show All

• .NET Development Data Adapter not generating a table

  Hi, I'm having a problem with my tables. I created a data adapter, configured it and generated the dataset. The table shows up in the dataset, but when I go to bind my controls to the columns, through properties, the table is not there. I also need this table for Crystal reports and it's not showing up in that list of tables either. I've tried several things including: 1) deleteing everything and starting over. 2) deleteing everything, checking in all my changes, compiling the project, then starting over. 3) all in #2 plus rebooting then starting over. 4) whine to the boss for some help. none of this has worked. ca ...Show All
