So where you placed the edit control ? dialog or window ?
and which function you using for showing dialog(DialogBox() ) ? you will get the hwnd of dialog in dialog Proc.

if it is dialog put your dialogs handle in SetDlgItemText

Hopes this helps

You passing wrong value as third parameter, it should be message to send(WM_SETTEXT in this case).

Modify your code to,

SendDlgItemMessage(hwnd,IDC_PATH,WM_SETTEXT,0,(LPARAM)szDir);

You can use SetDlgItemText either.

And also I want to know how to disable and enable edit box ???

use:

BOOL EnableWindow(
  HWND hWnd,     // handle to window
  BOOL bEnable   // flag for enabling or disabling input
);

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

HWND hEdit = GetDlgItem(hDlg,IDC_PATH);//hDlg handle to dialog
EnableWindow(hEdit,FALSE);//disables window
and 
EnableWindow(hEdit,TRUE);//enables window

Hi All,

The MeasureItem is called for owner draw menu at the time of creation. But how can I invoke it again (for some size changes)?

Thank you.

it will be automatically called when the menu needs to shown (in the case menu item). if it is a main menu try invalidating the main window.

If u can Dream... U can do it

No, it will be called, when menu is created, just once.

u r right prasad Laugh | :laugh:

. But i found a solution. U can just add items again. so that measure message will be sent again. in this case reload all items will work , i think.

If u can Dream... U can do it

Do you mean SendMessage WM_MEASUREITEM? Then what about the wParam and lParam?

As per MSDN this message is sent by the system. Please explain.

I have a ownerdrawn menu which is already created. But i need to change the text after some time. If the text is larger than the previous one it will be clipped. So need to update the menu size. Thats all.

How you are setting this text ?
One solution could be, Keep member variable of type CString for youe menu class.
Keep a function, that will set this text. And while setting this text, use CDC::GetTextExtent to calculate string size. and Use CWnd::MoveWindow for changing its size.

void CMyMenu::SetText(CString& sText)
{
  CPaintDC dc(this);
  CSize szSize = dc.GetTextExtent(sText);
  ..logic to decide menu size
  MoveWindow(..);//new size 
}

I've not tested this code.

if u want to calcualte the size of items , try adding all items again. I check it with combox with style Variable.
This time measure items will be called . Big Grin | :-D

Happy coding.
