Ok,

We are trying to move a project from a folder called 'proj2' to a folder called 'proj'. Both folders are in the exact same root folder.

The project worked just fine under 'proj2', but has met the max number of build errors in the 'proj' folder.

Here are some examples:

alpha(10) = Chr(10 + 64) <-- "Name 'Chr' is not declared."
Dim blue = RGB(219, 229, 253) <-- "Name 'RGB' is not declared."
"Name 'vbCrLf' is not declared."

There are more including DataSet having an error.

The weird thing is that we have a reference to System.Data in the project!

The next weird thing is all these things worked no hitch before.

Any ideas?
