CSingleLock Assertion Failed

[mcgmil]

Hi I am using CSingleLock in a program with a primary thread and a worker thread. On start up or if I do certain operations (both in debug mode) the debuger throws up a Debug Assertion at line 160 in mtex.cpp. Line 160 shows the floowing ASSERT(!m_bAcquired); Does anybody know what the problem is as it’s driving me crazy. Thanks in advance. MTM

This apparently is not VC++ v6. Correct?

How are you creating the singlelock? it seems that the syncobject you are using its not valid. Example: CCriticalSection g_CS; //global or class member func() { CSingleLock SLock(&g_CS, TRUE); } Good luck. -- modified at 8:50 Wednesday 12th July, 2006

I am Using Visual C++ Standard 2003 In the document header are the following declarations CCriticalSection ImageInfoSyncObject; CSingleLock * pImageInfoLock; In the constructor of the document .ccp file a new single lock object is created CDoc::CDoc() { pImageInfoLock = new CSingleLock (&ImageInfoSyncObject); } Then I use the lock and unlock within a function. Void CDoc::Function() { pImageInfoLock->Lock (); //Code . . . . pImageInfoLock->UnLock (); } Has anybody any further ideas as to why I get the Debug Assertion Failure for mtex.ccp line 106 Thanks MTM

If i put this code in a function it works perfectly (in VS2005), Try it: { CCriticalSection ImageInfoSyncObject; CSingleLock * pImageInfoLock; pImageInfoLock = new CSingleLock(&ImageInfoSyncObject); pImageInfoLock->Lock(); pImageInfoLock->Unlock(); }
