QAxBase Error calling IDispatch member occures only when Debugging without Breakpoints

[JohnSRV]

Hello Everyone,

I'm having a weird situation when I run the following Code

if (ZFsolutionFile.exists())
{
    {
	printf("The Solution exists! Opening...\n");
	pSln->Open(ZFsolutionFile.fileName());
 	printf("Solution is Open\n");
    }
		

EnvDTE::Projects *projects = pSln->Projects(); //Get Array of all Projects in Solution
if (projects == NULL)
{
       printf("ERROR: No project objects could be found.\n");
       return -1;
}
		
pPrj = projects->Item(QVariant(1)); // Choose first Project of Solution
if (pPrj == NULL)
{
        printf("ERROR: Project object could not be created.\n");
	return -1;
}

When I debug this Code with Breakpoints it works fine! When I run it without Breakpoints i get the following Error

QAxBase: Error calling IDispatch member Projects: Unknown error

Why does this occur when not using breakpoints and how to fix it ?

Thanks in advance
