POC++ Loadlibrary() error 3765269347

Body
copied!<p>I have got this Loadlibraty() error 3765269347 bothering me. I am implementing a C++ console application, built as x64, to load a x64 native C++ dll. Following is the code in the C++ console application to load the dll:</p> <pre><code> bool InitDll() { HINSTANCE hInst = LoadLibrary(_T("C:\\TIS_Nick\\Hardware\\Devices\\ThorDetectorSwitch\\TDSTest\\TDSTest\\Debug\\Modules_Native\\ThorDetectorSwitch.dll")); if( hInst != NULL ) { FreeLibrary( hInst ); return true; } else { DWORD err = GetLastError(); return false; } } </code></pre> <p>I got err is 3765269347, which I think means C++ cannot handle this error. I am sure my path to load the dll is correct. </p> <p>I also use <strong>Monitor Process</strong> to trace what the dll and functions get called. and here is the information I think relevant. </p> <pre><code>11:08:07.3196483 AM TDSTest.exe 1604 QueryNameInformationFile C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\x64\Debug\TDSTest.exe SUCCESS Name: \TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\x64\Debug\TDSTest.exe 11:08:08.5720585 AM TDSTest.exe 1604 CreateFile C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll SUCCESS Desired Access: Read Attributes, Disposition: Open, Options: Open Reparse Point, Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a, OpenResult: Opened 11:08:08.5721041 AM TDSTest.exe 1604 QueryBasicInformationFile C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll SUCCESS CreationTime: 6/11/2013 6:30:08 PM, LastAccessTime: 6/11/2013 6:30:08 PM, LastWriteTime: 6/12/2013 11:00:28 AM, ChangeTime: 6/12/2013 11:05:51 AM, FileAttributes: A 11:08:08.5721293 AM TDSTest.exe 1604 CloseFile C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll SUCCESS 11:08:08.5722797 AM TDSTest.exe 1604 CreateFile C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll SUCCESS Desired Access: Read Data/List Directory, Execute/Traverse, Synchronize, Disposition: Open, Options: Synchronous IO Non-Alert, Non-Directory File, Attributes: n/a, ShareMode: Read, Delete, AllocationSize: n/a, OpenResult: Opened 11:08:08.5723228 AM TDSTest.exe 1604 CreateFileMapping C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll FILE LOCKED WITH ONLY READERS SyncType: SyncTypeCreateSection, PageProtection: 11:08:08.5724896 AM TDSTest.exe 1604 CreateFileMapping C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll SUCCESS SyncType: SyncTypeOther 11:08:08.5725861 AM TDSTest.exe 1604 Load Image C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll SUCCESS Image Base: 0x7fef7830000, Image Size: 0x6d000 11:08:08.5726385 AM TDSTest.exe 1604 QueryNameInformationFile C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll SUCCESS Name: \TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll 11:08:08.5728910 AM TDSTest.exe 1604 CreateFile C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll SUCCESS Desired Access: Generic Read, Disposition: Open, Options: Synchronous IO Non-Alert, Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a, OpenResult: Opened 11:08:08.5912215 AM TDSTest.exe 1604 CloseFile C:\TIS_Nick\Hardware\Devices\ThorDetectorSwitch\TDSTest\TDSTest\Debug\Modules_Native\ThorDetectorSwitch.dll SUCCESS </code></pre> <p>I aplogize that looks a little messy, I was trying to post a picture here, but it turns out I don't have enough reputation to do so. Any suggestion is appreciated.</p> <p><strong>Update</strong> I have traced down to the constructor in <code>ThorDetectorSwitch.dll</code>, which looks like following:</p> <pre><code>ThorDetectorSwitch::ThorDetectorSwitch() : _mcSwitch(__uuidof(MCLControlClass)) { _A = WstringToBSTR(L"A"); _B = WstringToBSTR(L"B"); _C = WstringToBSTR(L"C"); _D = WstringToBSTR(L"D"); _deviceDetected = FALSE; } </code></pre> <p>I set the break point at the first parenthesis, but it never gets into the function. Instead, it jumps to the exceptions. I suppose something wrong with the <code>MCLControlClass</code>, or<code>_mcSwitch</code>?</p>
