Hi,
My application requires that the system does not go to
sleep mode. That can be achieved by calling
UpdateSystemActivity() from an NSTimer. That prevents
the system from going to sleep when my application is
running.
However, if user manually put computer to sleep from
Apple Menu->Sleep, then

If a combo box is using a Data Source, then how do i

My question is,

Hi,
I am having a problem with the way my application displays text. In my
application, i have some NSTextFields (static text) on a custom window of mine.
But the static text is not readable when application is launched. It is too
blurred. At first i thought it was because the text size is smal

Hi,
My scenario is a little different than what you have described. I don't have
images on buttons. I have my custom window (which is a black colored image) and
on it are the static texts. These texts are displaying blurred. Although i have
not been able to figure out why is this happening, but

Hi,
I am encountering a small problem. I am using a simple NSTextField in my
application. This textfield is editable. When user starts entering some text,
the auto complete is by default ON, so on pressing escape key a list of
suggestions is displayed. I don't want this feature. How can i turn
Thank you, implementing the delegate method and returning nothing from it
worked.
By the way, this is pretty basic stuff. I think there should have been a line

Thank you.

I am getting a strange error that i am unable to understand.

But why would it round 863.6 ? I mean there is only 1 digit after the decimal.
It should not have the range problem with a value this small.
