Use GetSystemMetrics

How do you propose using GetSystemMetrics() to get the "physic memory size and information of chassis" as the OP has requested?

I don't think you can do it.

Of course you can hide the folder but for making it inaccessible to be edited or viewed I don't think there is an API for that.

Are you wanting to do this programmatically, or use the OS to do it for you?

Subclass CEdit and handle WM_CHAR message.

If the char entered is a valid number then call base class implementation else you can ignore the char.

Instead of creating the control variable of edit box as string, use integer type. if u wan to get the number as string just use the "Format" function of the CString.

Then set Number (ES_NUMBER) style of the edit box, which only allows interger to enter.

There is another way toooooooo

Add the Number style to Edit. Whenever you want text in the edit box, Just call

GetWindowText()

Thanks a lot to all of you as all are good suggestions. But as per my requrement i feel "Add the Number style to Edit" will be the best solution. But i do not know exactly how to set it and also i am not able find the same.

Nave,
Can you please tell me how to set this style.

on the resource editor, there is a "decimal" property which make the editBox accept only the 10 decimal digits...
if you'd like to allow the . character, or a sign character like + or -, you'll have to overload the WM_CHAR event...

First Load menu resource using LoadMenu(...)

Second Set menu for the frame using SetMenu(...)

For eg:

CFrameWnd *pFrameWnd = (CFrameWnd *)AfxGetMainWnd();
CMenu cmenu;
cmenu.LoadMenu(IDR_MYMENU_RESOURCE)
pFrameWnd->SetMenu(&cmenu);
pFrameWnd->DrawMenuBar();

on the resource design editor, open your dialog/frame and check its properties ; you'll find a "menu" option... there, change it for you IDR_MYMENU

please, don't leave it as IDR_MENU1 as the wizard autogenerate ; give it a more significant name Wink | ;)
