OK. I want to access the textbox value from the module. Dont tell me I have to declare a variable for every control and every control's properties. Or could modules be a nasty no no in DotNET? I have google and yahooed and I cant find ANY example anywhere of how to access properties of form controls from a module. My six year old could do it in VB6. How???
