First of all, thank you Michael for helping me resolve my problem.
For the benefit of those who may have a similar problem, this is what I did to resolve it:
I created a new directory for my project files:
C:\CodeBlocks
No white spaces in the path as per Michael's advice.
I downloaded the latest Nightly build and extracted it to:
C:\Program Files\CodeBlocks\CBNB
I then added mingwm10.dll and wxmsw26u_gcc_cb.dll to the above directory.
Afterwards, I launched the Code::Blocks application from within:
C:\Program Files\CodeBlocks\CBNB
Everything loaded fine.
Finally I created a new "Hello World" console project, compiled it, and runed it.
Everything went well and my code executed as it was supposed to.
Now, as this is the first time I use the Nightly builds, should I copy the lib folder and other folders or files from the initial Code::Blocks folder:
C:\Program Files\CodeBlocks\
to the Nightly build folder?:
C:\Program Files\CodeBlocks\CBNB
Thanks again for your help!
Chris
