I'm trying to use a resource file (.res) I created when working with VB6. I googled a bit, and found some code examples. But I keep getting the following error:

Code:
System.Resources.MissingManifestResourceException:

Could not find any resources appropriate for the specified culture (or the neutral culture) in the given assembly.
Make sure "Cards01.data.resources" was correctly embedded or linked into assembly "Cards01".
Cards01 is my project name, Data is the name of the .res file.

The code is as following:

Code:
resourceManager = New ResourceManager("Cards01.data", System.Reflection.Assembly.GetExecutingAssembly)
Code:
picStatus.Image = resourceManager.GetObject("601.bmp")
Basicly the program can't find the damn thing. But I tried all sorts of different syntaxes for parameters, with and without extensions. (eg. "Cards01.data.res", "data.res", "data")
The .res file is added to my project by clicking on "add existing item..."

Can anybody see what I'm doing wrong?
