Hi, Larry. This function is a little strange. You pass a pointer to a buffer and the function puts the pointer inside the buffer. The microsoft-provided VB example uses a function called copymemory string to get the data.
The MSDN page uses this description which confused me at first """ BOOL WTSQueryUserConfig( LPTSTR pServerName, LPTSTR pUserName, WTS_CONFIG_CLASS WTSConfigClass, LPTSTR* ppBuffer, DWORD* pBytesReturned ); ... ppBuffer [out] Pointer to a variable that receives a pointer to the requested information. The format and contents of the data depend on the information class specified in the WTSConfigClass parameter. To free the returned buffer, call the WTSFreeMemory function. """ which means that my buffer end up _containing_ the pointer. I imagine I'm going to have to write a simple module that can get string by address. -Mark On Tue, Aug 27, 2002 at 02:23:20PM -0500, Larry Bates wrote: > Mark, > > Normally when the objects work with pointers you pass > pointers to them and they fill in the information and > you access the information when you get back from the > function.
