View 5 RepliesI'm adding the icon image of a process and adding it to a PictureBox. I want the image to be centered, but it's stuck in the Top Corner of the box.
VB.NET
Dim ico As Icon = Icon.ExtractAssociatedIcon(p.MainModule.FileName)
Properties.picProcess.BackgroundImageLayout = ImageLayout.Center
Properties.picProcess.Image = ico.ToBitmap
I'm setting the Layout first and then adding the icon. I've tried the reverse and I still get nothing.

I have made a program that has an image moving across the screen. The image changes its movement direction when the arrows are pressed. Now, I am trying to rotate the image (an arrow) to match the direction. Here is the subroutine to rotate the image. It uses the hidden PictureBox2's image (the original right arrow) as the source, because I couldn't think of any other way.

Just want to know the best method to load a picture in a picture box dynamically. As part of my development, I was supposed to load 4 pictures from network to 4 picturebox controls.
For which, I found, 2 methods.

(or)
2. Piturebox1.ImageLocation="C:\test.jpg"
Which one is more suitable interms of performance.

I have a picturebox and I am trying to create a masking system to use in different graphics projects.Is there a simple way to select an object with pixel precision. For example if I have a picture of an animal, how can I select it by moving the mouse over it with precision instead of selecting an entire rectangle area where the object might be transparent?
Is there a way to do this with the builtin capabilities of gdi+ or is this something that requires code? If it does require code, does anyone have an example of this?

View 11 RepliesI have a form containing a listbox showing a list of image names. It's bound to the database table. When an image name is clicked it shows the image and imagename in a picturebox and textbox respectively. When no image is selected in the listbox, a new record can be inserted by browsing a new image in the picturebox by an openfiledialog, writing the imagename in the textbox and pressing the OK button. When an image is already selected, the record can be updated by pressing the same OK button. The data is saved into MSSQL Server 2005. Corresponding table fields are Keycode int autono, logoname nvarchar(50), logo image.Now the problem, when I insert a new data with an image everything goes fine but whenever I try to update an existing data with an image it throws an exception- 'A generic error occurred in GDI+.' at the following line- 'pic.Image.Save(ms, pic.Image.RawFormat)'. Surprisingly when I update an existing data without any image in the picturebox no exception is generated. I have crossed checked it and seems that the problem is just at one point- 'Updating the image from the picturebox'. My code to insert/update the data by OK button and to populate it by listbox doubleclick follows:
