FIX: Component Gallery Errors with Read-Only Project Files

• The Component Gallery, included with:
  • Microsoft Visual C++, 32-bit Editions, versions 4.2, 5.0

SYMPTOMS

When inserting a standard MFC component from the Component Gallery, a message box appears with the following text:

Errors encountered:

<a long list with no filenames>

Continuing may render your project unbuildable. Continue?

CAUSE

Source file permissions are read-only, perhaps due to source control.

RESOLUTION

Change the source file permissions to permit write access. In a source control environment, this may require checking out the file, or having the file's current owner check it back in.

STATUS

In Visual C++ version 6.0, the IDE no longer hangs when the Yes button in the previous error message is clicked. However, the inability to add controls to read-only files is a restriction of the operating system and is by-design.

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a new MFC AppWizard (exe) project.



2. Change the file permissions to read-only for all files except the .ncb file.



3. On the Project menu, click Add to Project, and then click Components and Controls.



4. Select Visual C++ Components, and insert a status bar (select "use the system defaults" in the wizard).
   
   NOTE: The message box described in the SYMPTOMS section appears.



5. Click Yes.
