Question

Possible duplicate:
Target form1.designer.cs and form1.resx

I understand that the * .designer file is grouped with the window form / file. But not sure what the relevance and use of the attached * .resx file is.

Can I create a form / control with a file attached to it?

Answer 1

The Windows Forms Designer saves the created forms by generating code. Many control properties, however, are difficult to express in code. For example, the Icon property of a form or the ImageBox Image property. Many bytes associated with them. The .resx file format has been optimized to store these property values.
