Hi. I want my view support zoom in/out feature, such as Word and Visio, user can set view scale to 400%, 200%, 100%, 50%, etc. Currently I implement this feature by GDI mapping( MM_ANISOTROPIC ), my view contain a workarea and some graphs( bitmap ), I change GDI mapping when user set view zoom. Now the problem is GDI mapping is not good when draw a bitmap, even worse then StretchBlt. what are you think about it? or have better ways to do it.

m_Child is my custom window and it derive from CWnd, this is SDI project, m_Chils is member of my view.

I write a control for script, but I can't return more then one parameters: [out] VARIANT param1, [out] VARIANT param2, [out,retval] VARIANT *pret now only one parameter will return well, is that script can't accept method that have more output parameters?

I using ADO to execute a stored procedure that will return a recordset and some parameters, but if I get the recordset will cause output parameters to be empty. rs = cmd->Execute( NULL, NULL, NULL ); otherwise, I remove rs then the output parameters will be right. cmd->Execute( NULL, NULL, NULL ); any idea?

Parameters.Refresh() method created all parameters that are stored process provide. but I can't obtain the value of output parameter after execute. Thank you very much.
