[ctlqt12]

Hi all, I have created a dll file in VC++ 6 and use that dll file in VB.Net. But unfortunately, in VC++, I'm using some datatype that aren't supported in VB.Net. So i couldn't use that dll file. Please show me what datatype i should use in VB.NET appropriate with following datatype in VC++ 6 : BSTR -> what datatype in VB.NET i should use LPCTSTR -> what datatype in VB.NET i should use LPSTR -> what datatype in VB.NET i should use unsigned int -> what datatype in VB.NET i should use DWORD -> what datatype in VB.NET i should use Please show me some guide. Any help will be welcome. Best Regards
