MAPISession.Signon changes default drive and current directory

[pcwc66]

After I issue MAPISession.Signon, the default drive sys(5) and current directory sys(2003) will be changed to c:\program files\common files\system\mapi\1033\NT. Is this unexpected change related to msmapi32.dll which is located in that directory.

Thank you for any info.

How does this relate to a VFP problem?

Hi Mike,

I'm using the MAPISession and MAPIMessage Controls in my VFP application. I don't expect that using those controls will change the default drive and current directory. In a way, you're right that this is probably an issue related to MAPISession and MAPIMessage Controls. However, since this issue is changing the running environment of my VFP application, I consider it is related to VFP too. In order to resolve this issue, I have to issue CD command to switch back to the original drive and directory before the Signon. Otherwise, the application will crash. I'm not sure whether it is an common issue in using ActiveX controls or not.

Yes, you've found the same thing I've found.
The default directory does change when instantiating the MAPI controls.

You can CD back to the right directory, and everything works fine.

I've never seen another ActiveX control do the same thing, but apparently that's because they were designed well....

Hi,
Although no MAPI-issue, same happens (change of defaultdir) to me when printing using a PDF-driver.
