Hi Srini,

Are you talking the MissingManifestResourceException? This problem can occur when the resource can not be successfully loaded.

Do you have any custom classes defined before the default Form1 class? Since the compiler use the name of the first class as the default resource name for the form.

For example, you can find similar lines in the assembly's manifest (Note: You can check the compiled assemblies using ildasm.exe utility):

.mresource public WindowsApplication1.Form1.resources
{
}

As you can see, "Form1" is from the name of the first class in the code module. If you put another class, "MyClass" for example, before the "Form1" class, the resource
name will be changed to "WindowsApplication1.MyClass.resources". This makes the call:

System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(Form1));

fail to locate the resource.

If this is not the case, please explain a little bit more about problem, and I'm glad to look into it.

Regards,

Felix Wu
