My development environment is 7 + VS2008, do is a related to fluid simulation software, you need to install Flowmaster v7.5, then control the supplier provides a xx. DLL interface for the call, then another. H file and. CPP files, in providing the test code, the other parts are no problem, but when you perform a function is a function of the analysis results, the speed is very slow, and sometimes can succeed, but sometimes the exception,
Call this function code is: the network RunAnalysis (" zz ", "vc call", "SS", FALSE, FALSE);
Tracking in function source code is
Cstrings IDE_Doc: : RunAnalysis (LPCTSTR sOwner, LPCTSTR sDescription, LPCTSTR sAnalysisCode, short shtHeatTransfer, short shtComponentInteraction)
{
Cstrings result;
The static BYTE parms []=
VTS_BSTR VTS_BSTR VTS_BSTR VTS_I2 VTS_I2;
InvokeHelper (0 x9, DISPATCH_METHOD, VT_BSTR (void *) & amp; The result, parms,
SOwner sDescription, sAnalysisCode shtHeatTransfer, shtComponentInteraction);
return result;
}

Is mainly the function call takes a long time, and whether the compiler can repay an unhandled exception COleDispatchException
According to my previous experience the teacher, the process should be as long as a second or two, but I like to perform a speed is too slow,
Due to frequent calls in your code, so definitely not reality, excuse me everybody, know that this is what reason, thank you very much,

CodePudding user response:

Excuse me what reason is this? Got several days do not have what idea, interface is encapsulated couldn't open to see what's inside, is what needs to be set in the software, or VS what you need to import or use the OLE controls Settings? Hope have the relevant experience of the comrades to give directions

CodePudding user response:

Interfaces are packaged can not open the COleDispatchDriver is where come of?

Exception must be taken down and report to the user (for example, lets users choose to retry or cancel), abnormal contains messages also help in the diagnosis of the reason,

CodePudding user response:

Capture COleDispatchException, see whether there is an error message,
Or output parameters passed to control the provider to help analysis
