If I make changes to the registry (these changes will effect Win95), how
can I make Win95 update and refresh the registry, and thus make the
changes to windows95?
How can get the string value(sub key like string value, DWORD value, Binary value, etc.) from registry?
For example if my app sets the flag for a registry key, via the registry, how can I make windows95 refresh the registry and make the change?
Im using VC++ 6.0.

By using the registry API (e.g., RegOpenKeyEx(), RegCreateKeyEx(), RegQueryValueEx()).

Which type is your application ? if it is a MFC dialg based app the paramter to SetDlgItemText is correct , otherwise u need to provide the HWND of your dialog in SetDlgItemText function.
SetDlgItemText(<dilogs handle="" hwnd=""> , IDC_PATH, szDir);
Refer MSDN.

Hi krishna,
I am using Win 32 Application.

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
If u can Dream... U can do it

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.

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

use:
BOOL EnableWindow(
HWND hWnd,
BOOL bEnable
);

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  . 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.

I am discussing about context menu. And SendMessage to which window? Please explain.

|
|

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.
