It is not a problem in the source code but with project files.
I have found a backup and it compiles well.
This time I had not copied an existing project but started with an empty one.
I don't like Pelle's editor and now I don't like Pelle's Project manager.
I think I am going to create a cmd file to build the program and use it under Notepad++
There is an include file "Ressources.inc" that I cannot add to the project.
There are others *.inc file into the project.
When programming in assembler it is not strange to have *.inc files!
Some weeks ago I had a similar problem, I resolve it adding an other include file in the source code.
The include had nothing to see with my problem.
The problem was I cannot create a toolbar and I included sqlite3.inc!
That means you have to do many backups of the project.
When my project was at a point I could reuse its code I copied into an other project and made an other Skeleton project.
What a good idea I had, Now for each step I make 7zp backup.
I would appreciate this problem to be resolve by PO.
Now you know why my avatar is GRUMPY
