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

Thanks Rajesh, for the link and tip.

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 | :)

So what is your suggestion pal. At the time IsTextUnicode is working fine.

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 | :)

c2120 error

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

Regards

Does WWGetProfileInt() returns a value???

yes, the prototype is this

Yet your previous code showed WWGetProfileInt(). Which is it?

Because you are missing a comma after "test123"?

If you remove the bAllowDeleteSystemVars =, does the error persist?

Just double-click the key/value you wish to edit. The registry editor (regedit) is not that difficult.
