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...]

Floodfill With A System.Drawing.Graphics() Object

Jun 7, 2011

I need to make a basic drawing program in VB that can do three things:

"Draw" with a brush of some sort
Clear the screen
Perform a flood-fill (paintbucket action)

I decided to do the first two tasks first, and got them to work, but the third task completely eludes me. Every way I try seems to pile on exceptions, and every flood-fill algorithm I find seems to require a bitmap, rather than a Graphics() object. Is there any way to accomplish a flood-fill using a Graphics object, or must I restart the project using a bitmap?

Source code for reference:

Value Of Type System Drawing Image Cannot Be Converted To Integer

Nov 26, 2010

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.

Using System.Drawing To Make A Selection Tool, And Cropping An Image In .net?

Sep 4, 2009

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.

Interface And Graphics :: Making A Custom Class That Mocks The System.Drawing.Rectangle Class?

So I changed the _onPaint event but nothing is working out when I run the program?
