The memory for the character array is on the heap.

CString uses heap to create char array.
devvvy wrote: CString strNewString; << Local variable declared on Stack but seems like it allocates on heap since it can be called from "Main".
strNewString = strOriginal.Mid(2);
oList.AddTail(strNewString);
Actually, CString class uses class CStringData, which keeps tack of this buffer using reference counting.
In this case AddTail cause to increase refernce count by 1, thats why buffer contained in strNewString will not be destroyed even though object goes out of scope.

Send custom message to dialog, which has the tab. Handle the message in the dialog and close it as you like (say OnOK or OnCancel or EndDialog ...)
or
If the dialog is the parent winodw for the tab then simply call
GetParent()->EndDialog(..);
Hope i understood your question..

Just use the tabdialog instance to call its method (make sure the access specifier for the methos is public)

Did u Create the tabdialog before calling the method..
Simply
CMyTabDialog m_wndMyTabDlg;
m_wndMyTabDlg.MyMethod(...)
will lead to crash, because u didn't create the tabdialog...
You have to proceed like this
CMyTabDialog m_wndMyTabDlg;
m_wndMyTabDlg.Create(...);
m_wndMyTabDlg.MyMethod(...);
Refer MSDN for Create

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...

yes thers no error but it does not clear the edit boxes(done in the function)
Arise Awake Stop Not Till ur Goal is Reached.

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(..)
{
m_wndChild.ClearEditControls(..);
}
Hope its clear..

sorry i cant understand that can you please send me the sample code
Arise Awake Stop Not Till ur Goal is Reached.
|
|
|
|

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)
