i have a picturebox with a background image...above it are drawn images and shapes.... i want to save this as a jpeg image.. i use the following code
SavefileDialog1.ShowDialog()
PBoxf.Image.Save(SavefileDialog1.FileName, System.Drawing.Imaging.ImageFormat.Jpeg)
where pboxf is the picture box. but the image saved always has a black background..
After pressing a button Private Sub btn1_Click(sender As System.Object, e As System.EventArgs) Handles btn1.Click
[Code]...
It works, just that there is any "white flash" when the appearance of the form .... I also tried on another computer (both powerful processor and graphics) ... It 'can be improved?
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'm doing a simple form tat could add picturebox during runtime and i could add several picture into it.

View 10 Repliesclick on a picturebox and get a 'mark' to appear. (This currently works just fine using the code below.)I would like to have only one mark on the picture box at a time, i.e., I need to remove the previous mark on each mousedown event and I am unsure of how to get this done.Once the user has placed the mark correctly on the picturebox they will fill out a few extraneous textboxes of information and press a 'save' button. This will update a table (currently access) with that extraneous data plus the x and y of the mouse position when it was clicked.What I would like to do at this point in the process is remove the mark from the picture box and in it's place add a premade 'pin'. Sort of the thing you do in google earth. This would be a jpg or bmp or png file. The type does not matter.

I'm studying Visual Basic (using Visual Studio 2008) as part of an all-round IT foundation degree...I must confess that programming is becoming my weak spot! Unlike the C++ I was taught last year, I'm not finding VB too easy...probably becasue I've never programmed this way before and I've missed a couple of lessons.

1. is it possible to have a picture in a picturebox and then drag it to another so it gets placed there? if so, how? 2. can you assign a picture a name? because if i move it a cant use a code like this: picturebox1... = whatever. if so, how?

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?

Hey I am making a GDI++ game in vb.net. Now what I want is the monster(picturebox) to go after the player(picturebox). There Are No Vertical Walls. Only The Edge of map barriers. For example to get to the player the AI would have to go to the end of the ledge and either jump off and fall to the lower ledge or take the ladder down. There is no jumping, only falling and going up and down ladders and across the horizontal ledges. So How Can I make this pathfinding system?

I need to plot some analog values read from the serial port.I plot them in a picturebox starting from left. When I reach the end of the control at the right side I shift all values to the left of a point and I plot the new point at the right, (I have some flickering but it could be acceptable). This is my plotting control.My problem is that I have to clear the control (picturebox) in order to plot the shifted graph, but the method Clear of the Graphics class clears everything inside the picturebox, even my grid.How can i make always visible a grid "in" my picturebox?
1.a transparent image with a grid over the PB? (the clear method cannot remove it)
2.an image with a grid below the picturebox that must be with a transparent background to make visible the grid?
3.multiple layers on the same picturebox?
