SYMPTOMS

RegistryKey.setValue might not set the value of a registry key correctly. This problem only occurs on Windows NT.

CAUSE

The setValue( ) method, when executed under NT, does not account for the terminating null character, which causes incorrect data to be written to the registry key.

STATUS

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

This bug was corrected in Visual Studio 6.0 Service Pack 3. For more information about Visual Studio service packs, please see the following articles in the Microsoft Knowledge Base:

194295 HOWTO: Tell That Visual Studio 6.0 Service Packs Are Installed

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a new "Console Application."
2. Import com.ms.wfc.app.*

3. Add the following code to main( ):

   RegistryKey r = Registry.CURRENT_USER.createSubKey("Software\\Microsoft\\VisualStudio\\6.0\\Debugger");
           
   r.setValue("Test1","ABC");
   r.setValue("Test2","DEF");
   r.setValue("Test3","XYZ");
   
   r.setValue("Test2","");

4. Compile and run the code.
5. View the specified keys in REGEDIT.
   
   Without Visual Studio Service Pack 3, the key "Test2" will hold the value of one of its peer keys.
