• Visual Studio Undocumented error (ESS_SS_HISTOPEN) in VSS 6.0

  Hi All, I'm automating VSS through the COM interface and I consistently get the same error when attempting to do a 'get' operation on items in my database. The error being returned is 0x8004D75C, which I mapped to ESS_SS_HISTOPEN (or "A history operation is already in progress"). Aside from an entry in ssauterr.h, I can't find any documentation that gives me any idea what this error actually means. Anybody have a clue Sean ...Show All

• Smart Device Development CameraCaptureDialog Issues

  I've been having some issues using the CameraCaptureDialog class on an HTC Apache device (rebranded as the UTstarcom 6700): 1.

This happens whether I dispose of the class instance or not, and the Close() method is protected, so I can't call that. Any ideas on getting rid of this lingering capture screen 2.
