CDialog - Assertion Falied!

I have created a Dialog Application with a main menu bar
The menu bar has an option that opens a new Dialog (new Class)which contians serveral controls, in particular a CIPAdressCtrl.

I cannot pass data to the CIPAdressCtrl using DDX, as I can only map a variable as a control.

I want to pass information to the control, then show the dialog.

This is the code I am using, which is contained in the main Dialog application class.

Code:

---

void CNetworkAccessDlg::OnMenuChangeip()
{
        CIPSettings dlg;
        dlg.m_ipAddress.SetWindowText("0.0.0.0");
        dlg.DoModal();
}

---

However, when executing and selecting the menu option to show the dialog I get a Debug Asserion Error.

Why is this and what do I do to avoid this?

Thanks

You cant set the text of a window (or control in this case) before it's created - common sense.

First of all, I'd use CIPAddressCtrl::SetAddress to set the IP

Change the contructor of the dialog (or add a function to be called before DoModal) to accept the bytes of the IP, and pass in the info you want to set. Store this info as a class member, then set the control using CIPAddressCtrl::SetAddress in the InitDialog function of the dialog class

I have tried adding a function before the doModal call to set the values, but I get the same error message.
