Hello Joan, Thanx for your fast reply. Is it possible do change dynamicly from the parentsDialog to the ChildDialog without to destroy the ChildDialog. I want to change the HIDE and SHOW behaviour of several Child Dialogs. How can I do this? Without using of DoModal() only with ShowWindow(). Cause if i do a DoModal() i can not make any interaction with my parentDialog while the ChildDialog is open. Wihtout a DoModal and just ShowWindow it does not work. Assert @ runtime. So i dont know how to solve this Problem. I want to use the Std Afx Message Functions of each Child Dialog. Maybe you have an advice. See you Andre

Thanx for your fast reply. I have tried something like this what you have wrote. Problem of your Code above is that the compiler will generate an error cause of CDialog has no member m_myEditCtrl. Now i had the Idea to deriver the CDialog Class with my Dialog Class e.g. mySubFormDlgClass. The Code look something like this mySubFormDlgClass *pdlg = (mySubFormDlgClass*)m_Forms.GetAt(index); with this Construction there is no error but an Assert @ runtime! So this is not the way. Another Problem is that if i insert some AFX Messages with Classwizard into my mySubFormDlgClass,set breakpoints in this Event Functions and want to debug - there is no interruption. The Event does not occur. So only a ShowWindow takes places, no DoModal() function. Maybe there is the Problem. If i do a DoModal the Dialog opens but must be closed if i want to use my MainDialog while the other is open. I will research some time on this. Maybe you have some ideas. Thanks Andre

Hi, While Im using subForms in my Options Dialog, i want to read out the Controls Data, like text out of a CEdit Ctrl. Normally i would do this with DDX and Classwizard -> with result I have a variable which i can use. But with the use of subForms I have no scope anymore to these subForm Dialog Elements. Im using the SubFormCollection Class from the Article "Child Dialog (Sub Forms)" from D. Zuppinger. [http://www.codeproject.com/dialog/childdlg.asp] How can i retrieve the Data out of a Control in a SubForm Dialog to my Main Dialog?! So maybe somebody out there might have an Answer with a little bit of source would be great. Thanx to all in this community Andre
