• Scionwest Odd behavior on enter key twice

  Converting a program from VS03 to VS05 professional using VB... If you put your cursor after a line of existing code, and hit enter twice, it should just add a blank line and then you paste and then you paste new code and you get a line between your pasted new code and the existing code. In VS05, however, it does that and often highlights the last word of existing code so when you paste, you have messed up your code. This is an odd behavior that did not exist in VS03 and it very annoying. The behavior does not existing in any other program (like Word), so it is a VS05 specific issue. Is it a known bug or does anyone have any ideas Thanks! Bob Hi, Bob, I just gave this a try and I'm not able to reproduce the pr ...Show All

• WRBehning I'm making a conversion program...

  For those of you who know me, I've finally settled on an idea for a program. It converts (for starters) from anything that ends with meters (you know, centimeter, millimeter, kilometer) into anything else that ends with the word meters. You get the idea. I'm useing combo boxes, and I need to assign values to the names in the box, so they can be multiplied. Like, the selection (this is exactly what it looks like) "centimeter(cm)" needs to be assigned the value 0.01. How do I do that, and make it so that when one thing from one box is selected, and one thing from another box is selected, and a button is clicked, they get multiplied together Thanks. What you can do is set the entry in the combo b ...Show All

• SolarWind Memory Problem

  Hello everybody, I have a problem that my program takes a lot of memory. I have been told if i use "Dim ..... as string" it will take much more memory than what i need, and i can make a range for "String", but how note: In VB 6, its was like this:(if i only need 30 characters) Dim sth as string * 30 I saw this page, i was really amazed, i didn't expect that.
