Hi All,

I'm new to Visual c# 2008 and need to ask a question regarding images.

I have set up a window with an 'Image'. I have added an 'OpenFileDialog' component and can display images into the 'Image'.
My question is how can I reposition/move this image around the window?
There doesn't appear to be any x/y positions in the properties for an 'Image'.
Is using an 'Image' the correct way?

Thanks for any help

I'm confused, have you used a PictureBox, or are you drawing the Image object manually??

If you're using a PictureBox, simply create a new Point for the .Location attribute on the PictureBox. If you're drawing it manually, just change the co-ordinates.

Hi RudiVisser,

Thanks for your interest! - I'm using an 'Image' manually. I tried to add a PictureBox but get an error

"The type or namespace name 'PictureBox' could not be found (are you missing a using directive or an assembly reference?)"

Which namespace is PictureBox in? I can't find it anywhere.

Thanks very much

An Image is not a control, you didn't put that on your form.

You need to add using System.Windows.Forms; at the top of your code file to use PictureBox, and if you didn't create a WinForms application, you need to add a reference to that DLL.

I'm curious to see what code you're using?

namespace Ink_Pad

	public partial class Window1 : Window
	{
	  ...
	  ...
	  ...other code...
	  ...
	  
	private void button4_Click(object sender, RoutedEventArgs e)
		{
			//browse
			OpenFileDialog dlg = new OpenFileDialog();
			dlg.InitialDirectory = "c:\\users";
			dlg.Filter = "Image files (*.jpg)|*.jpg|All Files (*.*)|*.*";
			dlg.RestoreDirectory = true;

			Nullable<bool> result = dlg.ShowDialog();
			if( result == true )
			//if( dlg.ShowDialog() == Microsoft.Win32.DialogResult.OK )
			{
				string selectedFileName = dlg.FileName;
				//FileNameLabel.Content = selectedFileName;
				BitmapImage bitmap = new BitmapImage();
				bitmap.BeginInit();
				bitmap.UriSource = new Uri(selectedFileName);
				bitmap.EndInit();
				image1.Source = bitmap; //added in designer
			}
   }
}

Hi Rudi, just to clarify the project I am using was set up as a WPF project.
In the above image1 is an Image added with the designer.
This works (I can load/display a Jpeg etc).
At this point I got stuck as I couldn't find the positional properties for Image...

Thanks

OH WPF!!! I'm sorry, never properly worked with WPF, can get much better effects with custom WinForms IMO

Was just about to ask what a Window was

I would love to be able to offer help, but the last time I attempted to work with WPF, I also couldn't position anything via code, so I gave up trying.

Sorry.

Lol - no worries - Thanks very much for trying to help me though.

I did some googling, and eugh, I couldn't live with this rubbish.

Turns out that......

There is no absolute positioning in WPF. Instead, controls are automatically placed and sized according to their margins, the margins of adjacent controls, and the padding of their container. The system is very similar to that used in web pages.

Taken from here.

I don't understand how he compares that to web pages.. They're not meant to be APPLICATIONS. I stand by my good old "WPF is stupid" argument

EDIT: Might be best to post it here.. If it is possible you could get a better response -> http://www.dreaminco...howforum121.htm

Hi Rudi,

Bang goes my Quake beater in WPF then!!!
Maybe I should stick to WinForms. In your opinion would this be better for games?
I come from a C++ background and am not used to all this 'designer' rubbish!

Thanks

For games, I'd look into XNA if you want DirectX accelleration.

I managed to get a simple Panel control that will pump out about 90FPS, but this is all based on the users' CPU thanks to GDI+'s unaccelerated nature.

It really depends what you want to do.. C++ could well be the better option if you're making an "advanced" game (talking 3D n stuff)..

Thanks for the advice Rudi.
