Adding CW++ features to Visual C++

[Grant_LECO]

I've followed the Method 1 of the instructions in the Knowledge Base on how to Update an Existing Microsoft Visual C++ Project with New Tools for Visual C++ Classes in MEasurement Studio twice now with the same results. Both times it doesn't work unless I add some of the steps in Method 2 of the article. Once I get up and going however any Dialog Box that has a CW++ control in it doesn't display properly. Everything compiles nicely but then doesn't actually run right.

My question then is can you give me a hint on where to look for problems when everything seems to compile and link perfectly but then doesn't display on the dialog? I've really been careful with all the steps involved and so I don't think there is
an error on my part. There is so much going on behind the scenes when Mearsurement Studio creates a project that it's hard to recreate it all. I feel like I'm so close though when everything works fine unless there is a specific CW++ control in one of the dialogs. Class Wizard works great as well. As far as setting up member variables goes anyway.

Thanks for your time.

Grant,

One possibility is that your NI controls are hidden beneath a Group Box that is not set to be transparent. If this is the case, they will show up fine in the dialog editor, but when you run your program or "Test (Ctrl-T)" the dialog, the controls will not appear on the dialog You can change this by setting the Transparent checkbox on the Extended Styles tab of the Group Box property page.

FYI, the Windows stock controls (buttons, checkboxes, etc) show through non-transparent group boxes, but all ActiveX controls, such as the NI controls, will be hidden this way.

Hope that helps,

I thought I would answer my own question since I finally found the problem. Well, actually I found the right question and a friend at work found the problem.

Turns out the original project didn't have ActiveX controls enabled. Adding the following line in the InitInstance() of the application file:
AfxEnableControlContainer();
solved this problem. I would have thought that by trying to use ActiveX controls, like the CW++ controls, an error would be generated somewhere but there wasn't any.

Just wanted to post this in case anyone else had whole dialog boxes not appearing because they had a CW++ control in them and was wondering why.
