I've rotate pictures using code like this vb.net Picture.Image.RotateFlip(RotateFlipType.Rotate90FlipNone)
How can I remove any rotation? I have a code which rotates images but and saves the roation to a database.For example I save a value such as
1 = 90
2 = 180
3= 270
4 = 0 (no roation)
Now looking at the MSDN on this topic if I wanted a user to rotate the image by clicking a button i could rotate 90 or 180 or 270. However, If I load the image location and rotation from a DB and the rotation is "2" I want it to roate 180. But using the same code If a user clicks a button (which goes through the options 1-4) and they are on "1" then click it and it goes to 2 i would only want to roate another 90. As at one it's already moved 90 so another 180 would mean it's rotated 270 in total.
For this reason I can not load a image and move it 180, I thought okay if I'm at "1" going to "2" I'll move it back 90 then forward 180 but if a image loads at 4 what does it do? does it go back thinking it's come from 3 or load at 4?
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.
how to rotate an image inside a picture box. Saw many for VB6 etc, but when tried it in vb 2008 nothing worked and got lots of weird errors.My project is to read a compass (electronic) send to the PC then create a nice compass image to rotate accordingly. All the rest of my stuff works, GPS reading and parsing etc..But cannot for the life of me, get that image to rotate.

Is there a way to rotate a label such that it reads vertically? I've checked all of the label properties but there doesn't seem to be one that will do the trick.
For using you will need this two dll, I'm sure everybody knows that, but its probably the best. [URLs] (this example use itextsharp-4.1.6 )
My Question THe following Code will make a Graph, create a Bitmap, and start Adobe-Reade to present the Graph inside. The whole code works fine. I only have trouble, when I use this line: Dim Doc As New iTextSharp.text.Document (iTextSharp.text.PageSize.A4.Rotate())
Instead of this line: Dim Doc As New iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 10, 10, 10, 10)
The quality of of the whole Picture is not good then. Eventhough when I change width and hight for the Rectangle. Then I tried to change the Bitmap width and hight, but in that case nothing happends? Any way, to handle the quality for using why nothing happens, when I change height or width in this line: Dim Doc As New iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 10, 10, 10, 10)
I have a PaintEventHandler connected to a picturebox via AddHandler.
In PaintEventHandler I have coded this for writing the drawing to PictureBox1.Image:
Dim PictureBox1 As PictureBox = CType(sender, PictureBox) PictureBox1.Image = New Bitmap(PictureBox1.Width, PictureBox1.Height) Dim bmp As Image = PictureBox1.Image Dim g As Graphics = Graphics.FromImage(bmp)
... drawing something ...
PictureBox1.Image = bmp
Everything works fine but after running through the paint event handler and showing the picture on the screen it calls the painthandler again and again. It does not stop.
Replacing the code above with
Dim g As Graphics = e.Graphics
Makes it running. But then I cant save the Image to a file.

I am writing an application that I am going to roll out in a few days. But I would like to play a prank on a coworker so that when the app runs it rotates on his screen.I am not sure this is possible, but if you have any neat little tricks to annoy a co worker Id love to hear them. Especially since the app relies on button clicks.

Is it possible to rotate the whole form and all the controls on it at once. If not a form then a panel with all the controls on it. It sounds like a strange thing to need. I can't find mention of it anywhere. Lots of stuff on rotating a picturebox or text. Right now I'm wanting to know if its possible or not and maybe a push in the right direction. The reason I need this is for the following idea.
A large touch screen laying flat on a table with people all around it (say something similar to MS Surface). Each person would have their own form oriented in the proper direction for where they are sitting so they could read it.
