Reading from an embedded resource stream

Question

I've been trying to access an image resource named "IndexPointer.jpg" in an embedded RESX file called "Images.resx". GetManifestResourceNames() returns a single value - SCtor.Images.resources".

Assembly::GetExecutingAssembly()->GetManifestResourceStream("SCtor.Images.resources.IndexPointer.jpg")

only returns a nullptr. Obviously, I've got the manifest name wrong. What would be the correct one ?

Answer 1

Open the assembly with Reflector to find out the correct resource name.

Answer 2

Well, I finally figured it out. Strangely, I recall coming across (and trying out) the working solution and disregarding it. In any case, I instantiated a ResourceManager object with my assembly's resource and used its GetObject method to extract the embedded image.

ResourceManager^ resources = gcnew ResourceManager("<rootNamespace>.<resourceName>", Assembly::GetExecutingAssembly());
Bitmap^ Image1 = gcnew Bitmap(dynamic_cast<Image^>(resources->GetObject("<nameOfTheImageResourceWithoutItsExtension>")));
