Windows(Cpp>>DLL<<VB6)

[Yelve Yakut]

Hello,

I am currently messing around with some sample code I found
It is about linking VB and CPP through DLL's

http://www.flipcode.com/articles/article_vbdlls.shtml

There is a string embaded in a strunct.
There is a function in a DLL that takes this struct.
This struct comes from a Visual Basic application.
My code changes this string.
But when I output the string in VB i can only see its first character.

I'm trying it for two hours now, any suggestions on this would help.

Thanks for the help in advance


void __declspec(dlle xport) CALLBACK StructExample(t estStruct *data)
{
data->shortVar = 1;
data->ucharVar = 'b';
data->floatVar = (float)3.4;

data->stringVar = ChartoBSTR("Ove rwrite");
}

////////// Convert a Character Array to a BSTR String //////////
BSTR ChartoBSTR(char * String)
{
int Len = strlen(String);
unsigned short FinalStr = new unsigned short[Len];

MultiByteToWide Char(CP_ACP,
0,
String,
Len,
FinalStr,
Len);

return(FinalStr );
}

Try asking in newsgroups which discuss any or all of
Microsoft Windows, Visual Basic, and "DLL"s.

Only ISO standard C++ is topical here.
You can use e.g. www.groups.google.com and/or www.usenet.org
to locate newsgroups about these topics.

Also, www.msdn.microsoft.com has links to groups about
Microsoft products and technologies. That site also
has literally thousands of technical articles about
Windows programming.
