Since your writing a wide char text, either you have to use wofstream instead of ofstream or
Covert the elementValue[i] to mutibyte using sprintf() or WideCharToMultiByte() before writing..

If i need to draw 10 images by considering the height of the CDialogBar window and it should exactly fit to the window even after changing the size..

Dynamically drawing 10 images to an area depends on the no of pixels.. Do you checked the minimum pixel area required to fit 10 image in the dialog bar

How to draw dynamically buttons on a Control dialog bar on LEft side of the MainFrame.
Ex if i want to draw 10 buttons with respect to the Size of the CDialogBar in a mainframe.
Then it should exactly fit to the screen.

Don't "draw" them yourself. Simply create them dynamically using CreateWindow.

I hope you mean wide characters(UNICODE) and multi byte characters. Try the IsTextUnicode() function.

I was going to suggest him that, but this API is not guaranteed to work all the time.

How ever I doubt if we test only IS_TEXT_UNICODE_ASCII16 or IS_TEXT_UNICODE_REVERSE_ASCII16 using this function, it will work fine. isn't it?

It should, but I do not know it for sure. As Kaplan says, we cannot expect something that was built ages ago to work flawlessly with a dynamic standard. Smile | :)

I don't have an alternative suggestion at the moment, my post was merely a hint to make you aware of the downsides of it. I am not sure if any substantial amount of efforts were put in lately to make the discussed API more reliable. I'm glad it worked fine for you. Smile | :)

Hi,

We are making changes in our application. Instead of writing in ini we writing in a local file. So we wrote a wrapper for GetProfileInt and GetProfileString.

But this piece of code is giving error.

bAllowDeleteSystemVars =
        WWGetProfileInt("test",
            "test123"/* "AllowDeleteSystemVars" */
            NULL);

where bAllowDeleteSystemVars is a BOOL variable. I am getting the following error
error C2120: 'void' illegal with all types
