BSTR When "getting" a BSTR property, the memory containing the string is allocated with SysAllocString. When this string is no longer needed, free this memory by calling SysFreeString if you are working in an environment such as C or C++ that does not automatically delete the memory. VB automatically deletes the memory, so VB programmers do not need to free the memory themselves. AppID; |
/* application ID that is doing the calling */ |
|
long Flags; |
/* flags */ |
Locks all modules of the same AppID that were unlocked using ILMDSKernel2::UnlockModule.
