BUG: "Debug Assertion Failed" Dialog Box When You Build an MFC Application with "Container/Full Server" Compound Document Support (315476)

The information in this article applies to:

Microsoft Visual C++ .NET (2002)
Microsoft Visual C++ .NET (2003)

This article was previously published under Q315476

SYMPTOMS

When you build a Microsoft Foundation Classes (MFC) application with "container/full server" compound document support, you may receive a Debug Assertion Failed dialog box with contents similar to the following:

Program: i:\content\GenAssert\Debug\GenAssert.exe
File: docmgr.cpp
Line: 339

After you click Retry, a Send error report dialog box is displayed.

CAUSE

This behavior occurs if the string resource that is generated for the document template is missing a "." character.

The wizard-generated string resource is as follows:

MyCLass\nMyCLass\nMyCLass\nMyCLass Files
*.myc)\nmyc\nMyCLass.Document\nMyCLass Document

This resource should be as follows:

MyCLass\nMyCLass\nMyCLass\nMyCLass Files
*.myc)\n.myc\nMyCLass.Document\nMyCLass Document

NOTE: The missing "." character in the wizard-generated version is in the "nmyc" section of the string.

RESOLUTION

To work around this issue, manually edit the resource (*.rc) file to add the "." character.

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
