• JoseEjecutin Program doesn't terminate

  Hi, i'm doing a program but i found something that isn't supposed to happen... When i click in the X to terminate the program instead of going to the menu the program closes but the task stays active... it only stops when i kill the task... someone knows why this happens Was this a upgraded application from a previous version of VB If you look in My Project -> Applications -> Shutdown Mode. I guessing you're calling Application.DoEvents. I'll explain more if I'm on the right track... HI, I remember in my VB6 days when this used to happen.

• Tdah Handling Repeated Arrow Keys

  I was amazed to read that noncharacter (eg. arrow) keys do not raise the KeyPress event in VB2005! I am developing a program where I want to capture, say, repeated down arrows key presses ... where the user holds down the DownArrow key for a few seconds and the program captures them all [the program has an overflow feature in the event the key is held down too long]. Am I correct in reading that this is not possible in VB2005 Surely not. Thanks. Oops ... I didn't make myself clear. I want to allow the user to hit the down arrow key and hold it down and as those repeated down-arrow characters come in I want an event handler to "capture" them. I have a stack mechanism where if the cha ...Show All

• Snickel65 Object oriented issue puzzles me

  I have a project with a form and 2 classes: Form1, clsAcad.vb and clsAcadPlot.vb I'm trying to keep all my objects in the classes but most methods of these classes use the same objects. This forces me to initialize same objects in both classes, then apply methods on them. So, using code in Form1 I'd have to make sure I pass the same document names to variables in both classes before using them. Can I retrieve the object from the class to the Form1 and pass it to the other class I guess not, that would be a violation of the encapsulation concept. I could combine the 2 classes in 1 In this case I'll have a large class with many methods useless in other projects. Should I use inheritance Is there an easier way of doing this ...Show All
