Hi guys n gals... mega nubie here

completley new to this c~ stuff, kind of feel like i am on the brink of understanding it but keep getting stuck, completley stuck.

i am on a mission to create the best image editor program for an assignment towards my uni degree.

i have created a window, i can open close jpeg/bmp files and rotate them in the x & y. no mean feat but for me its a miricle : )3

anyway i am trying to follow some code that allows me to generate a small window displaying image info, see below, anyway i keep getting error messages, i know to you guys they may be stupid and easy to cure, i got no chance on my own..
please help me find out whats wrong with this code...

private void imagePropertiesToolStripMenuItem_Click(object sender, EventArgs e)

{

string w = memBitmap.Width.ToString();

string h = memBitmap.Height.ToString();

string vRes =memBitmap.VerticalResolution.ToString();

string hRes = memBitmap.HorizontalResolution.ToString();

string pFormat = memBitmap.PixelFormat.ToString();

string phyDim = memBitmap.PhysicalDimension.ToString();

MessageBox.Show(

"Image Width =" +w+ "\n"+

"Image Height =" +h+ "\n"+

"Verticle Resolution =" +vRes+ "\n"+

"Horizontal Resolution =" +hRes+"\n"+

"Pixel Format = "+pFormat+ "\n"+

"Physical Dimension = "+phyDim+"\n"+

"image Information",MessageBoxButtons.OK,MessageBoxIcon.Information);
