Easiest way would be to add a PictureBox control at runtime and load the picture from the file, e.g.

void LoadPicture()
{
  PictureBox picBox = new PictureBox();
  picBox.Dock = DockStyle.Fill;
  picBox.Image = Image.FromFile(filename);
  this.Controls.Add(picBox);
}

when im using the from file it displays the error like this. 'System.Drawing.Image' does not contain a definition for 'FromFile'

Try:

.BackgroundImage = new Bitmap(filename);

stil it gives the same error. and there is no property called "BackgroundImage".

Sorry it's the Image property on the PictureBox control.

after using image property also,it gives the same error.
In FromFile we have to give the filename or the path of the image.

They're the same thing aren't they, you can use a relative path or an absolute one as long as the image is somewhere on the filesystem.

Check the documentation for the Image object and see which methods are supported by the CF (I don't use the compact framework so I'm guessing (intuitively) here).

The reason you get this compilation error is that you method declares that it will return an instance of DataSet, but not all paths return such an instance. Look at what happens if an exception is raised.

To solve this, you need only to put this line:

outside of the try{}catch{} block.

In the Main method there will be a line like this:

Application.Run(new StartUpForm());

Change the form that is instantiated.

Vipin Venugopal31-Jul-06 17:58

31-Jul-06 17:58

ok i got u now. What u have to do is from the print application u have developed remove the code. and paste it in the other form. the code u have to remove is

[STAThread]
static void Main()
{
Application.Run(new Form1());
}
and since u have developed the print application and other application differently. u might have to remove the code only form the print application. there is no need to do anything else on the other form ok. even after doing this if its still not working then u just right click the solution of the project take properties there in the general tab u will see StartUp object there u set the form which u want to run first. ok do let me if it works ok.
