问题 I'm working on an application in VB6. I came across what seems to be a small issue, however it is annoying and I am unable to fix it. What I'm doing is trying to pass 2 values to a function....

问题 I am new to vb 6.0.

问题 (I'm using VB6 but I imagine this comes up in most other languages.) I've got a GUI button that calls a routine that takes a minute or two to complete. I want impatient users to be able to click on the button a second time to have it gracefully exit out of the routine at any point. I used a static variable to make this work pretty well (see code below), but I'm cleaning up the project and I want to put the For/Next loop into its own function, since it's required in several different places in

问题 When I use an MSScriptControl in VB6, and set UseSafeSubset = True , what kind of things can't I do? I mean, what Controls can't I use? Or maybe some core Objects can't be instantiated or used? Maybe I can't CRUD files? I need a definitive list, please. This thread tells of a special flag in the registry that sets which controls are blocked when UseSafeSubset = True , but it doesn't elaborate on it. It says it should be easy to search, but two days of Googling found nothing. 回答1: VBScript had

问题 In VB6 there is a Form event called LinkExecute witch I can use to link tow projects together. For example I create project A with a button and link it with project B witch has a textbox when I click on the button on project A the textbox in project B changed. To simplify the idea it link the tow projects and make one of them listen to the other events and when a specific event occur on the main project the listener fire an event locally on the listener project. Both projects are WinForms and
