View 7 RepliesI am using the e.graphics.drawstring to print labels and textboxes. One of the labels is "#". Whenever I print, although it is centered in its label on the screen, the text in the label aligns to the left. Is there a way to get it to center? This is happening with all my textboxes and labels.

I was unhappy with the kerning in one of the installed fonts on my system, so I re-defined the kerning in a font editor and installed the revised font (under a new name) on my system. When I use the new font in Microsoft Word or Adobe Photoshop, my new kerning works fine - but when I use Drawstring in a VB program, although the new font is used, the kerning instructions are ignored.Does anyone know if this a feature of the Graphics.Drawstring method, or am I failing to set a switch somewhere? If it's a feature, is there another method which kerns correctly?

I am trying to use DrawString to write text as an image and then rotate it 90 degrees. It works fine with both a bitmap or directly on a PictureBox, but the big difference is in the quality. The PictureBox text drawn has great quality and looks nice. When I draw it on an image it looks horrible and blocky. I've made a few changes to try and get it to look nicer, but it doesn't look nearly as nice as it should.

I'm making a class to basically print the screen. I'm going through each field and doing a drawstring, but things aren't lining up correctly. I tracked the problem down and don't know why it's happening.Take this line of code as an example:
Me.CreateGraphics.DrawString(Label1.Text, Label1.Font, Brushes.Black, Label1.Left, Label1.Top + 30)
This should draw the same text that is in label1 directly below label1 on the form. However, the drawn text is a different length than the label's text. Courier draws shorter, Sans Serif draws longer. It's doing the same thing going to a print document; it isn't matching how the label is being rendered.
I have a treeview containg a hierarchy of fire stations with child nodes being the trucks in the stations. I drag and drop trucks into listboxes that represent incidents. All this has a SQL Server DB behind it. As the trucks are logged into the incident a SQL notification returns the update and I use recursive call code through the nodes to set the backcolor of the truck node to red, (not available). When the truck is released from the incident the same process sets the backcolor back to empty,(now available). The code works just fine until. If you exit the screen and then return back to the screen suddenly the setting of the backcolor no longer works. The code runs as I have stepped through it and the line setting the backcolor is processed but the display in the treeview does not change.I have tried, after finding the node making it the selected node and using the afterselect event to change the color. That worked until exiting and reentering the screen I found that the afterselect event did not fire after setting the selected node.When you enter the form with the tree view the tree view is rebuilt each time taking data from the database and presetting the backcolor for any trucks already involved in an incident.If you completely exit the application and start up again there is no problem with backcolor settings, the problem is only if you stay in the application and exit and reenter the form with the treeview.I am using VS2008 and I have tried the application on Windows SBS 2003 R2, Vista Premium and XP Professional all with the same result.

View 5 RepliesI'm a VB beginner.I've been playing with Graphics.DrawString by watermarking a picture with a text string. The picture below to the left comes from PictureBox with a text string drawn with Graphics.DrawString. The font style used is Arial 48 points, regular, I think. The picture in PictureBox shows just as I configure. Great... The resolution of the original Terri Hatcher picture is 300 dpi (300 x 300). Exporting this picture with Graphics.DrawString, I get the picture below to the right. The text string appears a lot bigger than previously shown in PictureBox. It turns out that the text size varies, depending on the resolution of the original picture. That's kind of odd. I develop several graphics applications in a different environment and have never seen this sort of graphics.drawstring thing. Anyway,
my sample application seems to draw a text string at an image resolution of

I have noticed that when I use drawstring to only print numbers, it just prints nothing. However if I put a letter in the string, it prints. So, "12345" will not work, however
"a12345" will work.
Example:
Dim g As Graphics = e.Graphics
g.DrawString("12345", myFont, getBrush(Color), X, Y)
Is there a transformation function that can be applied to the Graphics.DrawString to output text on an angle?
