I'm running an ipad project on XCode. My project builds and runs successfully. But the logger messages (cout/printf statements) are not getting printed. It was working fine. I don't know what I did.
This is how the debugger screen looks when the project is running.
Help please..

Works after restarting Xcode. Should be a glitch.

Try to quit and restart the simulator.
If that still doesn't work then put a break point right before and after your print statements and see if your program is reaching that point.
If it doesn't reach the print statement, then put a break point in your viewDidLoad function and check if your program is running at all or not.

My code was converted to these random characters at some point after I saved my program using Vi. I did this project for a grade in one of my college courses and didn’t get any credit, despite the fact that I spent hours working on my code for this to happen. If anyone knows how to convert it back to C++ I would be thankful.
Turns out I had saved my file under the wrong folder and I was able to recover my original file. Thanks to all for helping out with this! It seems like it always tends to be something so simple...

Whenever I start my command line, debug executable, whether using the debugger within visual studio or on its own, it always restarts once. It is the weirdest thing: I start it, it seems to be running and I can interact with it, but then a few seconds later it just restarts on its own. And this happens only once; the .exe that opens the second time is stable and will keep on running until I stop it. Any ideas on what is going on here? I tried googling the issue but not sure exactly what to search for!
As #drescherjm commented, the issue was my antivirus. Disabling it fixed the issue.

double testpower;
testpower = pow(400,-9);
testpower giving me 3.8146972656250003e-024 which is different calculator output of 4E-7
Anyone have any idea why??
calculator output of 4E-7
You entered the wrong calculation into your calculator.
You entered 400×10-9, instead of 400-9.
These are absolutely not the same thing!
The C++ program is correct: pow(400, -9) calculates 400-9, which is approximately 3.815×10-24.
Here is some further reading for you:
http://en.wikipedia.org/wiki/Scientific_notation#E_notation
4E-7 seems like you accidentally input 400 * 10^-9 or 400E-9.
You're looking for 400^-9, which should give 3.8146972656250003e-024.
The result you are getting 3.8146972656250003e-024 is completely correct. Maybe your calculator does not have that precission and that is why you are getting that error. Try to do 1/400^9.
I just tested 400^(-9) on the Windows calculator tool and I got the same output as your program. I think the program is fine, it may be your manual calculation that is the problem here.

I have error when I try qmake my project in release mode. In debug mode everything is ok, but when I change to release - 'magic' starts. I have no clue what is wrong. Before I could several times qmake release version. What am I doing wrong? (below some output - sorry for partly polish information)
ASSERT: "fileName.isEmpty() || isAbsolutePath(fileName)" in file Q:\qt5_workdir\w\s\qtbase\qmake\library\ioutils.cpp, line 61
20:20:45: Proces "C:\Qt\Qt5.1.1\5.1.1\msvc2010_opengl\bin\qmake.exe" zakończył się kodem wyjściowym 1.
(translate: 20:20:45: Process "C:\Qt\Qt5.1.1\5.1.1\msvc2010_opengl\bin\qmake.exe" finish with return code 1.)
This is not quite magical. You either used back slashes, etc, a.k.a. wrong input path or were simply facing this already fixed bug in later versions:
qmake is crashing with "Qwt 6.1 rc3" and Qt 5
As you can see, this was fixed in 5.2.0 when wrong path is supplied. Based on your comment that Q:\ was unknown for you, it could also be the reason for the crash.

I am loading a Gdk.Pixbuf from bytes:
_pixbuf = new Gdk.Pixbuf(bytes);
Then, I'd like to read the _pixbuf data. But, it appears that the data is actually loading in the background because the data doesn't exist for a while. If I wait, all is fine.
How can I either know when it is finished, or force the update?
It turns out that this code was fine... I was executing it in the graphics thread, and returning before it was done. Once I executed it so that it blocked until it was complete, then all was fine.
