[2008] Rotate a label How?

[morkie]

Anyone have on how to rotate a label it in to vertical?

[jmcilhinney]

You can't. If you want to orient your text differently then you'll need to draw it using GDI+. GDI+ drawing is done on the Paint event of the control you want to draw on. This will draw text vertically on a form:

Public Class Form1
 
    Private Sub Form1_Paint(ByVal sender As Object, _
                            ByVal e As PaintEventArgs) Handles Me.Paint
        e.Graphics.DrawString("Hello World", _
                              Me.Font, _
                              Brushes.Black, _
                              10, _
                              10, _
                              New StringFormat(StringFormatFlags.DirectionVertical))
    End Sub
 
End Class

You should read the documentation for the Graphics class, it's DrawString method and the StringFormat class, then experiment to see what else you can do.

I could quite easily answer your question but I'm not going to. It's my intention by posting here to help people become better developers. Handing people solutions on a plate that they could find for themselves relatively easily is not conducive to that end, as it doesn't develop people's investigative and problem solving skills. So, I'm going to reiterate my advice from my previous post:

You should read the documentation for the Graphics class, it's DrawString method and the StringFormat class, then experiment to see what else you can do.

If you do that then you'll have the answer to your question. In my example code I have passed six arguments to DrawString. What is each of those values for? If you don't know then you haven't read the documentation. Here's where you should start:

http://msdn.microsoft.com/en-us/libr....graphics.aspx

That's the documentation for the Graphics class. Once you've read that you can follow the link provided for the member listing. You can then follow the link from there to the topic for the DrawString method. You can then see the different ways it can be called and what each argument represents. Once you've done that you'll be able to answer your own question and you'll (hopefully) have learned more besides, including how to find information in the future. That will be far more beneficial to you as a developer than my simply answering your question.

another thing....what if i want to rotate progress bar or other controls like picturebox...
do i have to do that as your code below?

[jmcilhinney]

You cannot rotate controls. The ProgressBar control supports horizontal orientation only in Windows Forms. In Windows Presentation Foundation (WPF) it supports vertical too.

With regards to images, again, PictureBoxes cannot be rotated. If you want to display an image rotated then you must either rotate the Image object itself, which you can do in increments of 90 degrees with the RotateFlip method, or else you use GDI+ as for the text to draw the Image directly onto the form or another control. You call DrawImage to draw an Image but rotating one is a little more complex. Check out the following threads for examples.

if i not to rotate a progress bar...
so i need to draw it right?
But how i can do that...

[jmcilhinney]

There are definitely third party progress bar controls available that can be displayed vertically, although they may not look like the standard control.

To draw one yourself you have a few options. You could just use a Label or Panel and set its BackColor, changing the Height as the progress changes. You could also use GDI+ again and call FillRectangle. Finally, you could use the RectangleShape (I think it's called) from the VB PowerPacks, which gets added to the Toolbox with SP1.
