Notes:
C++/CLI: This solution allows you to load an image from an unmanaged resource in the assembly. In my case I added a .cur file to my .rc. The cursor had an ID of 101. After loading the cursor I assigned it to the Forms::Cursor.
Tips & Tricks:
To use integer resource ID instead of string, and avoid using MAKEINTRESOURCE, prepend the integer with '#'. For example, to use resource ID 32512, enter "#32512" for lpszName.
To load application icons of different sizes, use cxDesired and cyDesired (see the example).
Sample Code:
Please add some!
C++/CLI Example
using namespace System::Runtime::InteropServices;
using namespace System::Windows::Forms;
using namespace System::Reflection;
int a = LoadImage(Marshal::GetHINSTANCE(Assembly::GetExecutingAssembly()->GetModules()[0]).ToInt32(),101,2,0,0,0);
this->Cursor = gcnew ::Cursor(IntPtr(a));
Alternative Managed API:
- or to load an image from a managed resource (dll):
System.Drawing.Bitmap.FromResource
