BSTR, wchar_t and Character Arrays

[MoonchildHK]

Hi again,

I have a line of code from an example program like this:

CComBSTR bstrFileName( L"c:\\Test.avi" );

I want to replace the text with a string variable read from a text file. So I have something like...

char *FileName;
.
.
.
CComBSTR bstrFileName( charFileName );

But that doesn't seem to work :-( Does anyone have any idea how I can do this? I have look at websites that talk about converting char * to BSTR but it looks horribly complicated.. is there an easy way?

Thanks,

Moonchild

When I look into the helpfile I see that BSTR is only an alias for wchar*
So to convert a char* to BSTR, it is very simple :


char filename[10];
BSTR bFilename= (BSTR) filename;

the pointer bFilename points now to the string filename
