Hello everybody! This is my first project using U++. I want to build a program to solve the TRANSPORT PROBLEM, it's just then beginning, but I dont understand the error description. Details are below:
Source:
Tranmission.h

}
GUI_APP_MAIN
{
//int m,n;
Tranmission().Run();
}
In addition, there are 2 files: Tranmission.lay and Tranmission.iml, but they aren't involved with the problem (I think so  ). The parts of source code that are after "//" and covered by /*....*/ are just be add to source afterwards. And these are error descriptions:

There were errors. (0:00.60)
Please, help me. I dont know what happen. It's just the start to make interface, even I have not yet go to the main part of program. When I build any examples contained with U++, it's good.

But when I built it first, it was correct. After I added the parts that cover by /* ... */ and after //..., it was fail, and I've tried to solve by deleting them,..., I have not solved it yet. I think they're not involved with these bugs.
PS: Please replace Tranmission by Transport, it's new name. But these errors have presented.

Well, those errors you have listed are 100% caused by those two lines commented.
If uncommenting then produces another set of errors, it is another issue - I do not have enought information to resolve errors I am not aware of 
However, consider packing your package (dir that contains those files) using zip (all files!) and uploading to the forum. Then I can easily check it/fix it... post back
