thank you, It worked, but now I'm having trouble in referring to the file. I loaded file 'security.png' to folder 'texture' under the 'Content'. It now has a asset name 'security'. i try to load it with :
myTexture = this.content.Load<Texture2D>(@"Content\textures\security");
but it doesn't seem to be able to found the file... I've also tried 'textures\security' , and several other trial referral to the file. Is there any setting that must be made?
Edited : sorry.. No need to reply, I've solved the problem by setting compile action in properties to 'Compile' Thank you everyone!! :D
