I am making a dice game, and just wondered why this doesn't work:'If dcpic1.ImageLocation = "D:Documents and SettingsAdministratorDesktopVBYaktzis in progressDicesone.gif" Then'
how else can I check the location of an image ?[code]...
'ImageLocation not a member of windows.form.picturebox'
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frmMain As New Form3()

I am a little bit confused about PictureBox.ImageLocation and PictureBox.Image = Image.FromFile().
The problem: If I use PictureBox.Image = Image.FromFile() then I am not able to do something with the file unless I dispose the PictureBox (which I most likely don't want to do).
If I use PictureBox.ImageLocation instead, I get the same result but I am still able to delete / move / overwrite the picture file.
So, just to get confused entirely: What are the differences between PictureBox.ImageLocation and Image.FromFile? When should I use the first, when should I use the second?Listing SPEC's is not a review !!! :-)
I'd like to hide the contents of a picturebox while still preserving it's imagelocation, width, height, borderstyle, top, left, and sizemod properties. Is this possible?

how to check if a picturebox is inside a form?
View 7 RepliesI am trying to check if an image has been changed from a picturebox in a if statement. If I cant check if a image has been changed then can I check if a picturebox been clicked.
View 8 RepliesI have a form which contains a tab control with three tabs on it. On a second tab there is a PictureBox. The problem is I can't figure out how to check if the PictureBox is completely loaded.I can't put "pictureBox.CreateGraphics.DrawRectangle(Pens.Aqua, 100, 100, 100, 100)" into a form load event because picturebox is not active until I click on the tab2. It neither works with tab2.enter event nor any other events I have tried so far. However it works through the button.click event and it works briefly with the picturebox.paint event before its wiped out. So I presume it will work with a timer event as well.But the question is how to to make it work without a button or a timer?
View 3 RepliesLet's say I have a PictureBox with an image of a house, for example, and I want to know if the user clicked on the roof, the door, the window, or the walls.
Is there some way to, maybe, set up an If statement so that it checks what the coordinates of the mouse click was and compares it to a set of pre-determined graphed points to decide what object was clicked?[code]....

View 2 RepliesI 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 have a program I'm working on that, for one of the features, allows the user to drag an image from a picturebox, into the main form space, anywhere they want. [code]...

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?
