Any Way To Center Drawing String?
Oct 18, 2010
Working in visual basic 2008
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
MyBase.OnPaint(e)
For Each kb As KeyboardButton In _buttons
e.Graphics.FillRectangle(Brushes.White, kb.Bounds)
e.Graphics.DrawRectangle(Pens.DarkSlateBlue, kb.Bounds)
e.Graphics.DrawString(kb.KeyString, Font, Brushes.Blue, kb.Bounds)
Next
End Sub
How would I go about centering the drawing string. In this case the string is the letter "a".

When I call this Messagebox, is it possible to center the Messagebox on the parent form rather than centering it on the center of the screen?

I assume that this will be an easy one for you guys. I have never dabbled with drawing in VB.NET. I have searched the forum and Google already, but have turned up nothing to help me. Here is my problem. I have an image that is in an image box. I would like to draw a string of text on it, centered vertically and horizontally. Here is what I am using to draw the text.

changing the text alignment property. If I change it from left, center to right, you can see all three remain painted. It's as though nothing is being cleared before the next draw.(A screen shot of this is also attached)My best guess is it's the ControlStyles.Opaque(only thing I've changed between when it worked, and when I started to notice it wasn't)... But unfortunately I need this particular style for the transparency effect I'm looking for.

I'm saving the font of a label to a text file, and when I open the text file with my program, I want the label to have the same font that is listed within the text file. Now, the only problem I am having is that when I try to write the code for opening the text file, I can't set the font property of the label to a string. Label1.Font=[Font: Name=Microsoft Sans Serif, Size=9.75, Units=3, GdiCharSet=0, GdiVerticalFont= False]Here is what the code to open the text file and set the font of the label looks like:[code]The problem for the code happens at line 6. The error is: "Value of type 'String' cannot be converted to 'System.Drawing.Font'"ing each part of the font in the text file(i.e. Writing Font.Name and Font.Size properties in separate lines and then setting the label's font properties to each line accordingly), but I still get hit with the same error.

I have a question about drawing a string on a picturebox in the form load event. So I have a picturebox on a form and in the form load event of this form I have this code:
Dim gx As Graphics = PictureX.CreateGraphics
Dim f As Font = New Font("Arial", 8)
Dim brr As Brush = New SolidBrush(Color.Black)
' Add the copyright text
gx.DrawString("1", f, brr, 2, 5)
But when I load the program nothing is drawn in the picturebox. Is there something wrong with the code or should I use the paint event of the picturebox?
By the way I also used this code in another program and there it works flawlessly, everything is drawn in the right place there when i load the program.

I 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

Say I have 3 Buttons, labelled: Unit 1, Unit 2 and Unit 3. When I click on any button I want a drawing of that unit to appear on screen at a pre-specified starting point. Thereafter when I press any other one of the buttons the unit drawings appear alongside each other in a line. So I could end up with:

I am making a web browser using geckofx. I have put the favicon in a picture box but I have changed my mind and now I want it as the form's icon. The code for the favicon is:[code...]
The favicon works fine in the picture box but i think it will look better as an icon. If i change the line Me.PictureBox1.Image = favicon to Form1.icon = favicon I get the error Value of type 'System.Drawing.Image' cannot be converted to 'System.Drawing.Icon'. How can I get this to work?

how to center an external app on the screen, an example would be Adobe Reader, using either Process.Start or Shell. I've 'attempted' both but haven't found anything to control the position. I've also found some code using Api32 functions, FindWindow, MoveWindow, etc, but have not been successful at those either.
