i have created initially a dialog named landialog. this is the tab dialog

No matter how many dialog u have created already...
For every dialog you have to create it before using its methods or CDialog's APIs.

Its better u can post your code and explain wht u need?...

From main dialog
void NetConfig::OnClearbutton()
{
LANSettings lanPrc;
lanPrc.Create(IDD_LANSETTINGS,GetParent());
lanPrc.ClearAll((LPARAM)this);
UpdateData(TRUE);

}

this is what i need to call
void LANSettings::ClearAll(LPARAM lParam)
{
(GetDlgItem(IDC_EDIT_LSUBNET))->SetWindowText("");
(GetDlgItem(IDC_EDIT_LIPADD))->SetWindowText("");
(GetDlgItem(IDC_EDIT_LGATE))->SetWindowText("");
(GetDlgItem(IDC_EDIT_LDNS1))->SetWindowText("");
(GetDlgItem(IDC_EDIT_LDNS2))->SetWindowText("");

}
when we create the dialog its just entering in to its initdialog.

Instead of using GetParent(), use 'this'. Because the parent to the LANSettings dialog is NetConfig, not the Parent of NetConfig.

Otherwise the code seems perfect.Try the above...

The code seems perfect. But i have a doubt, is your edit boxes values are string. If so then the code will work.
But if your edit boxes values are integer then u have to use
SetDlgItemInt(...); as StDlgItemInt(IDC_EDIT_XXXX, nValue, TRUE or FALSE);
TRUE for Signed integer and FALSE for unsigned integer

its string only

Then i didn't see anything wrong in the code...
May be for a try..
Remove the UpdateData(TRUE) statement and
Use SetDlgItemText(...) instead of using GetDlgItem(..)->SetWindowTExt(..)

Make the instance as a member to the parent class.
Use the Create API in the OnInitDialog() method of the Parent class.
Then use the instance (member of that class).

Actullay i forget ut class names, so see the below ex.

class CParentClass
{
 CChildClass m_wndChild;
};

BOOL CParentClass::OnInitDialog()
{
 CDialog::OnInitDialog();
 m_wndChild.Create(IDD_XXX, this);
 ....
}

xxx CParentClass::ButtonClick(..)
{
 /* Don't create new instance for CChildClass here */
 m_wndChild.ClearEditControls(..);
}

Hope its clear..

GetParent()->EndDialog(nValue);
or
GetParent()->DestroyWindow();

nValue may be any numeric value... this will be the return value of DoModal

EndDialog gets an error "'EndDialog' : is not a member of 'CWnd'" and i cant use the other since this will close all the windows(running in background)

EndDialog is a method of CDialog and not CWnd, Just use MSDN...
you can find even more ways to do your job...
All these are simple tasks and u cn definetly get a way by browsing MSDN...

Use like this,

((CDialog*)GetParent())->EndDialog(...);

deeps_cute wrote:

EndDialog will also do the same... because u are closing the parent window, so all of its child window will be destroyed...

Hi,

I have a small query regarding HANDLE. What exactly it means. what type of data it will stores. Is there an specific structure
ot the HANDLE

Chinna.

A number assigned to a window that is used by the operating system to keep track of the attributes of the window. In a C or C++ library, a handle is a pointer.

For more information please go through the MSDN.

Regards,

Paresh.

I could be many things. It could be one thing in one OS version and an entirely different beast in another OS version. Possible implementations are indexes into arrays, keys into hash tables, a pointer to a data structure… The important thing is that all operations go through APIs so the OS is free to change the implementation and the code will still run without needing to be altered; as long as the size of the HANDLE doesn't change.
