The error is Value of type System.Drawing.Image cannot be converted to System.Drawing.Icon Is it even possible to make the favicon be the icon of the form?

I am making a web browser using geckofx. I have put the favicon in a picture box but I have changed my mind and now I want it as the form's icon. The code for the favicon is:[code...]
The favicon works fine in the picture box but i think it will look better as an icon. If i change the line Me.PictureBox1.Image = favicon to Form1.icon = favicon I get the error Value of type 'System.Drawing.Image' cannot be converted to 'System.Drawing.Icon'. How can I get this to work?

When I try and compile code in vb.net 2008 I get an error that says "value of type 'system.drawing.image' cannot be converted to integer. The error happens at piccolor.image
GetDIBits(Form1.PictureBox1.Handle,
picColor.Image , _
0, Form1.PictureBox1.Height, pixels(1, 1, 1), _
bitmap_info, DIB_RGB_COLORS)
Here's the code that explains what piccolor.image is, it's a picturebox on form1 that has an image
readpic(Form1.PictureBox1)
Public Function readpic(ByVal picColor As PictureBox)
GetDIBits(Form1.PictureBox1.Handle,
picColor.Image , _
0, Form1.PictureBox1.Height, pixels(1, 1, 1), _
[Code] .....
And Imports System.Runtime.InteropServices is on the top of the module, if u need more code then let me know. Also I wonder if there is a way to bitblt directly to a pixel array.

I have a program that creates a Treeview from information procured through an ODBC query and dumped into a dataset. I have three such queries set up via radial buttons as well as a refresh button that triggers whatever radial button is active at the time it's clicked. The purpose of this program is to allow drag-and-drop of selected nodes, ending with a post to the database that officially makes that change of assignment to the new node.

I', working on a program where there are several projects within a solution. The solution contains a forms application, a couple of class libraries, and a public interface.I'm running into a strange problem where I can access the system.drawing.bitmap namespace from the main form and from one of the class libraries, but when I try to access it from the other class library or the interface, it tells me it is not defined. I've tried importing it, and calling it directly with no luck.

If i wanted to crop an image in VB.net, how would I go about doing it? I am trying to let the user drag out the box they want (system.drawing.rectangle), and it will automatically remove the edges surrounding the box.
My first problem is primarily the fact that I cannot make the system.drawing.rectangle visible. It is not displaying at all, I am setting its location and height programmatically, but nothing is showing up. I know there is probably something fairly obvious I am missing...but I cannot seem to find it.
My larger issue, however, lies with the cropping itself. I cannot find any crop methods, at all. Is there a hidden one I am missing? Or must I code it myself? How would I go about doing this? It ought to be able to output to a bitmap image object.

I have a VB.NET Windows Forms app with a logo image on the form as a System.Drawing.Bitmap inside a PictureBox.I used the Visual Studio Designer to add the logo .bmp image so I don't currently have any VB code doing anything with it.I'd like to make the current logo a clickable object/button so when I click on it a file browser dialog opens and I can select a new image to replace the current image.The current image is a local resource and is set in a PictureBox as a System.Drawing.Bitmap.How would I replace that System.Drawing.Bitmap with a file selected from the file browser dialog?

I made a program with Visual Basic Express 2008. I got this error message when I try to close my program after running it. (PS: It is a simple code that can login into Microsoft SQL Server)The error message shows the error was caused by the "system.drawing" (Parameter is not valid). Also, I have been trying the code in VBA (Excel). When I tried to close Excel after running my code, I got the same problem (Microsoft Excel has encountered a problem and need to be closed.....) and the error report shows the error was caused by "system.drawing" as well.

I want to pass an optional parameter to a function of type System.Drawing.Color. The problem I am having is that when I declare the function it says "Constant expression is required" but I have tried variations of the following, including integers, full qualified indentifiers, even old vbWhite constants to no avail.
