Instructions This Control Panel wizard is pretty simple to use, you only have to privide: Name – Which should be unique, and not include spaces. Description – The string […]

The addin for visual studio is like the preprocessor in C++. The difference is that you can select which commands that are going to be replaced by the macro you have selected. A typical scenario could be: You are going to write a class member function. The function without code in it should look like […]

If you have ever asked the following questions: How can I implement Marshal-By-Value components? How can I create complex structures that the MS scripting engines can take advantage of? How can I use the ATL wizard to help me generate code? Then this article and its accompanying tools should help you out a great deal. […]

Here is one to open the stdafx.h of the current project. Sub stdafx() ‘DESCRIPTION: Opens the stdafx.h file of the current project. proj_path = ActiveProject.fullname ext = “” pos = len (proj_path) Do While ext “” ext = Mid(proj_path, pos, 1) pos = pos -1 Loop proj_dir = left(proj_path, pos+1) & “stdafx.h” documents.open proj_dir End […]

These macros were contributed by Guy Gascoigne – Piggford Here are a couple of macros that I find very useful, they allow you to comment or uncomment out the current line or selection. CommentOut is based upon a similar macro that was shipped with Visual Studio but trimmed to suit my needs better, the UnCommentOut […]

We had been using the MSMask.ocx control in our MFC application for almost a year. Recently a 200K memory leak was traced to the setText method (200K each time it was called), so we downloaded another masked edit class from the web, but it flickered intensely and the code was kind of icky. Anyway, I […]

The code included here implements what I call a Smart Edit control.  This began life in a sample from the MSDN called CTRLTEST.  This control was originally called CParsedEdit and it allows one to specify types of allowable characters that can be entered into an edit box.  I have changed its name to CSmartEdit and […]

In many resource applications, it is necessary to display a preview of the application’s dialog template resource(s). This article presents a class (CPreviewStatic) that can be used to preview dialog template resources at runtime with a single line of code! Using the CPreviewStatic class In order to use this class, simple place a static text […]

. I was going along, cheerfully using COM with Microsoft’s smart pointers when I discovered a glaring omission in the underlying _com_ptr_t code. It turns out that there is no way to use CreateInstance() to instantiate an object remotely. And there is no equivalent member function to CreateInstanceEx(). After a bit of digging around I […]
