SYMPTOMS
The following error message occurs when you follow the steps in the More Information section below using Visual C++ 6.0:

Sorry! An error occurred when generating the object.

Or, when attempting to insert a new ATL object or when manually adding an object from another project into a new ATL project, you may receive the error message:

Sorry! An error occurred when generating the object.



CAUSE
This is a bug in the Visual C++ product.

Or, a project dependency file may not be checked out from the file version control system or the file may be marked as read-only. Typically, a Resource.h or similar file may be marked as read-only.

This error can also occur if the Interface Definition Language (IDL) file parser has problems reading the Interface Definition Language file due to characters it does not expect. For example, a help string with square brackets such as the following may also cause the error: [            uuid(11110C7E-134E-4164-9E37-EEF94221BF7E), version(1.0), helpstring("[MyCompany] Software Project") ]



RESOLUTION
Check to see if the dependency files are read-only. If they are, check them out from the file version control system or change the file attribute to read/write. Also, check to see if your project contains more than one Interface Definition Language file with "library" blocks. If so, this error can also occur. This is because the Wizard utilizes only one Interface Definition Language file to write the IDL of the new object. When there are multiple IDL files, it cannot figure out which file to write to and failure occurs.

The workaround for the problem with the square brackets is to remove the brackets so that the string included in the "Symptoms" section instead looks like this: [           uuid(11110C7E-134E-4164-9E37-EEF94221BF7E), version(1.0), helpstring("-My Company- Software Project") ]



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



Step to Reproduce the Error

 * 1) Create a standard MFC AppWizard (EXE) project.
 * 2) Choose SDI in step one.
 * 3) Click Finish.
 * 4) Select the ClassView and right-click the project name classes, bringing up the menu.
 * 5) Select New ATL Object.
