RE: function template

Hi Manjree,
I noticed that there was no implementation of your CListCtrlSetup
constructor. Also, I did not see your invoker code snippets. Could you
please post all of them for further research?

I changed your code as following and it worked fine:
//--CListCtrlSetup.h
#pragma once

ref class CListCtrlSetup
{
public:
    CListCtrlSetup(void);
    template<class T> void InsColumn(T& lst, System::Data::DataTable^ table);
};

CListCtrlSetup::CListCtrlSetup()
{}

template<class T>
void CListCtrlSetup::InsColumn(T& lst, System::Data::DataTable^ table)
{
 try
 {
     System::Data::DataColumnCollection^ columns = table->Columns;
     System::Data::DataColumn^ column;
     CString str;
     int i, col = columns->Count;
     for(i=0; i<col; i++){
         column = columns[i];
         str = column->ColumnName;
         lst.InsertColumn(i, str);
     }
     //SetColWidth(lst);
 }
 catch(System::Exception^ e)
 {
     System::Windows::Forms::MessageBox::Show(e->Message, L".NET Exception
Thrown");
 }
}

//invoker code snippets
#include "CListCtrlSetup.h"
......
                CMyListView vv;
    CListCtrl& lst = vv.GetListCtrl();
    CListCtrlSetup^ s = gcnew CListCtrlSetup();
    System::Data::DataTable^ t = gcnew System::Data::DataTable("test");
    s->InsColumn(lst,t);

You may refer to my code snippets to see if it can help you resove this
issue. If you have any other questions or concerns, please feel free to let
me know.
