Project/Parameters/Add Library or Object:
"../Dev-Cpp/New Folder/lib/libcomctl32.a"
Correct?
Well, it shows a sucessful compilation, so why are you worried!?
Why have you changes the default library path to "C:/Dev-Cpp/New Folder/lib"? It should not need changing, and it should not contain spaces.
Because "../Dev-Cpp/New Folder/lib/libcomctl32.a" is a relative path, it will only work if your project folder is correctly located in relation to the Dev-Cpp folder. It is just a bad idea.
When you explicitly link a file, it must exist, even if your project references nothing from it, so it is a bad idea to link general OS libraries like that. Because you ill-advisedly modified the default library path, the -lcomctl32 option will link "C:/Dev-Cpp/New Folder/lib/libcomctl32.a" in any case, the explicit link is unnecessary and should be removed.
Since the code linked I have no idea why you are asking the question, or why you chose to screw with default library paths.

You can specify an absolute or relative path. Your relative path will only work if your project is is a first-level subfolder of c:\ (assuming you installed Dev-C++ in c:\dev-cpp).
Avoid paths with spaces.
I would also avoid adding third-party libraries to the Dev-C++ installation folder, unless it was installed by a devpak.
Why are you adding this file in any case? It already exists in c:\dev-cpp\lib. It is part of teh Win32 API.
If the path to libcomctl32.a is added to the library search list (c:\dev-cpp\lib already is), then just -lcomctl32 will do. Post the build log, that will tell us if you have it set up correctly or not.
