I used a picturebox to allow user draw lines by mouse. I used this code in mouse down:
Dim D As New System.Drawing.Pen(DrawingColor, 2)
Dim g As Graphics = PB.CreateGraphics()
g.DrawLine(D, X1, Y1, X2, Y2)
but when a window appear on front of picturebox... its seams that picturebox redraw itself, so drawn lines erased.
So I have this code to make a "windows taskbar". When you click on an item, it's supposed to bring that window to the front. The only problem is that's not happening. When I use Debug.WriteLine, it has the right window title, except it doesn't come to the front. What's wrong? There is no EntryPointNotFoundException or anything, it just doesn't bring the window to the front.

Form 1. I have 1 picturebox with image how to make when they move the mouse to the picturebox to show in right or left a new window (to read from form2) and when they moveout the mouse from the picturebox auto to close the window
View 4 RepliesI need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

Ok, so I have a new challenge for the D.I.C. Heads. I'm making a simple little game using VB controls. I know it's not the best idea in the world but it'll have to do for now!
Here is whats happening. I've created a class that inherits the PictureBox control that I want to use to place my game pieces on the playing field.
Dim pbArmyUnit(0) As ArmyUnit ' ArmyUnit is a Class that inherits Picturebox now I create the playing pieces at runtime as needed and append them to the array. Player currently buys the units and places them on the playing field.
[Code]...
On a side note how can I look at a stack of pictureboxes all created at runtime to determine whats at a particular location? Example. I move my army unit over top of the picturebox that shows my forest. How can I tell what picturebox I just moved on top of? does that make sense? I don't need code for this just directions on looking at the right info so I can figure it out.
I am creating my terrain at runtime as well since it's randomly generated. and I'm basically making an array of 192 pictureboxes with the appropriate terrain image as well as some other modifiers. Just like with my armies above I've inherited picturebox and created a terrain class array, this way I'm able to add my movement modifiers etc, directly to the picturebox I place on the screen. It's these pieces of terrain that I want to be able to check before allowing the unit to move into them! to get movement costs etc.
I have made a program in which a small space ship rotates, with some tutorials I found, then when i tried to move it I realized that .location does not work for bitmaps..

View 2 RepliesMy Front end is VB.net 2008.I have a form. In this form, I have a menu control, this menu control has four buttons.On clicking the first three buttons, open the window with Show() event. and the fourth button open the screen with ShowDialog().Now, One by one I am clicking the button , so finally i have now four windows of this application.(Three with Show() and one with ShowDialog())Right?
Now I am minimizing all the windows with the help of Window + D Button.After this, If I use the keyboard(Alt+ Tab) keys. This is opening the showDialog window on top because , Show dialog's TopMost = True.Now I come back to my problem. That's why I cannot use the show/Showdialog overloaded menthod to pass the Me/form-id .Again, I use the keyboard(Alt+ Tab) keys, to minimized all windows. In the taskbar and Startmenu properties ,I have selected the Group Similar Taskbar buttons.This resulted in the heap of my application windows, one on the other.Now i click on one of my application window , and If I click the window other then the Show Dialog opened Window, this is not bringing the show dialog window to topMost.
Note:- There is no parent child window requirement. That's why I can't use the Show/Show Dialog overloaded method to pass the Me/Form-id
I've looked and tried.. and for some reason just don't seem to be getting right now.

I am new to vb.net, from VB6. Trying to understand drawing a simple line graph into a picturebox, which was so simple in VB6 ! From code snippets, I can see the basic idea using an bitimage to draw the lines and then showing it in a picturebox. I don't understand how to (simulate) scaling of the bitmap's x/y scales like you could do with VB6's .Scale.
