问题 I have activex server exe that was building and registering fine on 32bit OS. I wanted to make 64 bit version of that exe by upgrading project to Visual Studio 2010 and changing platform to X64 which apparently doesn't work.

问题 The Microsoft Office support article "Add or register an ActiveX control" says: IMPORTANT: Not all ActiveX controls can be used directly on worksheets; some can be used only on Microsoft Visual Basic for Applications (VBA) UserForms.

问题 This seems to only happen in IE6 I have an activex form written in Delphi 7. A dialogue window opened from within the activex control in IE6 gets displayed on the taskbar - the users (for some reason) do not want the dialogue to show in the taskbar. So I set the dialogue's borderStyle to bsToolwindow. This hides the dialogue from the taskbar but also has the (side-) effect of hiding IE from the task list in windows, which means that you cannot <alt>Tab back to IE if you tabbed away. Question:

问题 I am creating an ATL 8.0 based ActiveX control in C++ using Visual Studio 2008. I need to create a sub-window and attach it to the ActiveX control. How do I get access to the HWND that is owned by the ActiveX control? Which ATL function can I override in order to use the HWND after the control's window has been created? 回答1: ActiveX would allow you to define your own methods on your own interface (to address Brians assumption), but that likely won't help here. The ActiveX control might very

问题 I have created a Windows Forms UserControl that can be exposed as an ActiveX Control. Now I am trying to do the same with a WPF UserControl. The Winforms UserControl base class I noticed is ComVisible however the WPF UserControl class is not. Am I trying to do the impossible?
