Hello EveryOne, Hi..I am doing one vc++ program in that i want to call VB OCX file.I am doing that but when i am accessing the funtions from the ocx or activex control it is giving error.in VB OCX program function is like this: Public Sub Processattendacne(strProcess As Integer) lblProcessing.Caption = strProcess End Sub when i am adding know then this function is like this: void C_UserControl1::Processattendacne(BSTR* strProcess) { static BYTE parms[] = VTS_PBSTR; InvokeHelper(0x60030000, DISPATCH_METHOD, VT_EMPTY, NULL, parms, strProcess); } I am calling this function in my program it is giving parameter missmatch error..like this.. void CPassingVarsDlg::OnGetIt() { // TODO: Add your control notification handler code here CString str='s'; m_UserVariable.Processattendacne(str); } ERROR IS LIKE THIS: :\Program Files\Microsoft Visual Studio\My Projects\PassingVars\PassingVarsDlg.cpp(177) : error C2664: 'Processattendacne' : cannot convert parameter 1 from 'class CString' to 'unsigned short ** ' No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called Error executing cl.exe. Please Help me out to solve this problem.I am not getting which datatype i have to use to resovle this problem. Reply me As Soon As Possible.. Thanks In Advance, Savitri

[military tone] Of course, Sir! [/military tone] If the function requires a pointer to a
BSTRobject, why are you passing aCStringinstance? :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.
This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. -- Iain Clarke

first i used BSTR* only but that time aslo giving error..so i changed again to CString only..I am fed up of this VB ocx..or tell me steps of adding vb dll into vc program..please tell me i am getting tension.. Thanks in advance, savitri
Probably you have to change the following lines
CString str='s';
m_UserVariable.Processattendacne(str);to something similar to (error checking omitted)
BSTR bstr = SysAllocString(L"s");
m_UserVariable.Processattendacne(&bstr);
SysFreeString(bstr);:)
