View 7 RepliesI'm quite new to VB Programming and I'm using Microsoft Visual Studio 2008 for programming. I'm writing an application that communicates with an Omron PLC via CX-Server Lite which brings some ActiveX plugins for VB. So far I solved a couple of problems and my application "is doing something" already.My question in the end might be really easy. I inserted 3 bitlamps (Omron ActiveX Components) in a form, gave them the size and position I wanted them to have. When I now start my application they show up in the wrong size. It seems as if they would keep there position but they simply have the wrong size and even overlap each others although I have them sorted nicely in Visual Studio.Another effect I have is, sometimes when I move the components around on the Form in Visual Studio they seem to be "behind" the Form. I can't see them anymore but i can highlight and move them.

-If there is none, Can I use COM component and bundle everything into one Executable? Also is it possible a list of controls in .Net as I find in vb6: url....
