FIX: Component Gallery Errors with Read-Only Project Files (182324)


The information in this article applies to:

  • The Component Gallery, when used with:
    • Microsoft Visual C++, 32-bit Enterprise Edition 4.2
    • Microsoft Visual C++, 32-bit Professional Edition 4.2
    • Microsoft Visual C++, 32-bit Enterprise Edition 5.0
    • Microsoft Visual C++, 32-bit Professional Edition 5.0
This article was previously published under Q182324

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?
Clicking Yes causes the Visual C++ IDE (Integrated Development Environment) to hang.

Other components may provide other errors indicating that the insertion failed. Some state that the control has probably already been added to the project.

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.
RESULTS: The Visual C++ IDE will hang in versions before Visual C++ version 6.0.
