Loading Resources in Win Forms App

[Paul Cheetham]

Hi,

I have several cursors which I have added to my project (c#) and set the
build action to 'Embedded Resource'.

I am now having problems trying to load these, and so I was trying to
find the resource file and check their names, to make sure I was using
the right one.
The cursors don't appear to be in any of the resource files.

Since I am trying to use the Win32 LoadImage function to load these from
the resource file, the name needs to be correct, but I can't even be
sure they are being included in the executable.

Can anyone tell me how I can be sure they are being included, and
determine their names, or perhaps someone has a working example of this?
(I am using LoadImage because I am trying to load colour cursors)


Thankyou.

Paul Cheetham.

You can check the names in the resources by putting this couple of lines in
your constructor. It's debug code so take it out once you've made a note of
the names.

foreach(string s in this.GetType().Assembly.GetManifestResourceNames())
System.Diagnostics.Trace.WriteLine(s);

Thanks Bob, That worked great.
(Sorry for the delay replying, been away for a couple of days)

Only problem now is even though I know the resource names are correct,
it is still failing to load my cursor.

The code I am using follows:


public static Cursor LoadCursor (string CursorName)
{
Cursor myCursor = null;
String Name;
IntPtr HCursor=IntPtr.Zero, HInst=IntPtr.Zero;

//Name = "Prologic." + CursorName + ".CUR";
Name = "ProLogic.Cursors.IRON.CUR";

HInst = Win32.GetModuleHandleW(null);

HCursor = Win32.LoadImage(HInst, Name, Win32.IMAGE_CURSOR, 0, 0,
Win32.LR_DEFAULTCOLOR | Win32.LR_DEFAULTSIZE | Win32.LR_SHARED);
//HCursor = Win32.LoadCursor (HInst, Name);
if (HCursor.ToInt32() > 0)
myCursor = new Cursor (HCursor);

return (myCursor);
}


public class Win32
{
public const uint IMAGE_BITMAP = 0;
public const uint IMAGE_ICON = 1;
public const uint IMAGE_CURSOR = 2;

public const uint LR_DEFAULTCOLOR = 0x0000;
public const uint LR_MONOCHROME = 0x0001;
public const uint LR_COLOR = 0x0002;
public const uint LR_COPYRETURNORG = 0x0004;
public const uint LR_COPYDELETEORG = 0x0008;
public const uint LR_LOADFROMFILE = 0x0010;
public const uint LR_LOADTRANSPARENT = 0x0020;
public const uint LR_DEFAULTSIZE = 0x0040;
public const uint LR_VGACOLOR = 0x0080;
public const uint LR_LOADMAP3DCOLORS = 0x1000;
public const uint LR_CREATEDIBSECTION = 0x2000;
public const uint LR_COPYFROMRESOURCE = 0x4000;
public const uint LR_SHARED = 0x8000;


[DllImport("User32.dll")]
public static extern IntPtr LoadImage(IntPtr hinst,

[MarshalAs(UnmanagedType.LPTStr)] string lpszName,
uint uType,
int cxDesired,
int cyDesired,
uint fuLoad);

[DllImport("User32.dll")]
public static extern IntPtr LoadCursor(IntPtr hinst,
[MarshalAs(UnmanagedType.LPTStr)] string lpszName);

[DllImport( "kernel32.dll" )]
public extern static IntPtr
GetModuleHandleW([MarshalAs(UnmanagedType.LPStr)] string lpModuleName );

}



Any insights?



Thankyou.
