Memory could not be read? (runtime) [solved]

[DrDonut]

Hi all,

So, I've just compiled a new version of a program that I've written earlier and that used to work just fine.

In this new version however, I've changed a lot of stuff.

It compiles just fine, the only warnings I get are "/* withing comment", so nothing critical.

When I try to run the program, I get the following error:
"The instruction at "0x6a340388" referenced memory at "0x00000001". The memory could not be "read". Click Ok to terminate the program, click cancel to debug the program."

Do you know what I did wrong?

The code is not too complex, it's just one window, no multiple threads, no file access whatsoever.

Here some info:
QT: 4.4.3
compiling: commandline
OS: Microsoft Windows XP Professional SP2

Thanks in advance

Hi,

Compile it as debug and debug it. You will see where is the problem.
We can't tell you where is the problem without the code.
A memory access error refers to a bad pointer access.

Hi, ^NyAw^

Thank you for your reply, and for pointing out that it probably had to do something with pointers, you where right.

Thing was that I tried to add widgets to a grid but had not used the line:

grid = new QGridLayout;

And I also found a connect statement for a timer that didn't exist.

Thanks for your help!
