• When I compile, I get the error «Value of ‘0’ is not valid for ’emSize’. ’emSize’ should be greater than 0…..parameter name: emSize.

  How have you determined that the parameter is 100?   For instance, when you insert a breakpoint at that line and run your code and the breakpoint is hit, what is the value of ‘x’?

• Acamar,

  I hardcoded the value of 100 into my program for testing.

  However, when I use MsgBox at certain place in my code, say after the conversion to Single from String, the value comes out as 0 at execution before halting.

  Then there is a problem with the conversion.  Show the code where you are actually creating the value for x.

  If you’re using .TryParse and accepting the return value — rather than checking the boolean that’s returned — that would explain it.

  I don’t know that you are but I’ve seen it before.

• Here is a snippet of my code:

  Dim txtUserFontSize As String
  Dim x As Single

  txtUserFontSize = «102»

  x = Convert.ToSingle(txtUserFontSize)

  objFont = New System.Drawing.Font(«Arial», x, FontStyle.Bold)

• I am not using TryParse. I am using the Convert.toSingle function.

• I am not using TryParse. I am using the
  Convert.toSingle function.

  Use
  Single.TryParse and confirm that the result is not zero.

  MsgBox can be useful as a quick and dirty check, but for accuracy you need to use breakpoints and watch variables.

• Here is a snippet of my code:

  Dim txtUserFontSize As String
  Dim x As Single

  txtUserFontSize = «102»

  x = Convert.ToSingle(txtUserFontSize)

  objFont = New System.Drawing.Font(«Arial», x, FontStyle.Bold)

  There’s something else going on:

  Dim txtUserFontSize As String
  Dim x As Single
  txtUserFontSize = "102"
  x = Convert.ToSingle(txtUserFontSize)
  
  Dim f As Font = New System.Drawing.Font("Arial", x, FontStyle.Bold)
  
  With Label1
      .Text = "Test"
      .Font = f
  End With

  

  It should work, although assuming that the user typed in a valid entry isn’t a great idea. TryParse will help, later, but first figure out what’s going on.

• I appreciate everyone’s help, but I think I am making my problem confusing and difficult to solve for everyone if I don’t include all the source code of my PRELIMINARY (no error-exception checking  code added yet !) program.

  My apologizes. So here it the code (a VS 2010 project with just one form).

  Public Class Form1
  
      Private m_objDrawingSurface As Bitmap
      Dim txtMessage As String
      Dim txtUserFontSize As String
  
      Private Sub ParseCommandLineArgs()
  
           If My.Application.CommandLineArgs.Count = 2 Then
              txtMessage = My.Application.CommandLineArgs(0)
              txtUserFontSize = My.Application.CommandLineArgs(1)
          Else
              MsgBox("Needs 2 text strings as a parameter!")
          End If
  
      End Sub
  
      Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
          ParseCommandLineArgs()
          Me.Text = txtMessage
          InitializeSurface()  
      End Sub
  
      
      Private Sub InitializeSurface()
          Dim objGraphics As Graphics
          Dim objFont As Font
          Dim FontSizeSingle As Single
  
          FontSizeSingle = Convert.ToSingle(txtUserFontSize)
          m_objDrawingSurface = New Bitmap(Me.ClientRectangle.Width, Me.ClientRectangle.Height, Drawing.Imaging.PixelFormat.Format24bppRgb)
          objGraphics = Graphics.FromImage(m_objDrawingSurface)
          objGraphics.Clear(System.Drawing.Color.Red)
  
          objFont = New System.Drawing.Font("Arial", FontSizeSingle, FontStyle.Bold)
  
          Dim drawFormat As New StringFormat
          drawFormat.LineAlignment = StringAlignment.Center  
          drawFormat.Alignment = StringAlignment.Center      
          drawFormat.Trimming = StringTrimming.Word          
  
          ' Draw the command line argument’s text
          objGraphics.DrawString(txtMessage, objFont, System.Drawing.Brushes.Black, New RectangleF(0, 0, Me.Width, Me.Height), drawFormat)

•             txtUserFontSize = My.Application.CommandLineArgs(1)

  You can use TryParse with that string.

  But you need to check that the result of the conversion is not zero.   You might also want to check that it’s not something ridiculous, like 0.5

  Use breakpoints and the watch facilities of the debugger to confirm that you are getting the command line arguments correctly.

  I can»t see where you are displaying the image that you create, but perhaps that code will be created after you get the drawing code to compile properly.

• James,

  You have to debug your code by setting break points as Acamar says. This one is a bit tricky.

  When your resize event is being called before the form load. So the reason emsize is zero is the command lines have not been processed. I put checks for that and I made it call resize from form load so the bitmap is sized before the surface is initialized.

  If all you want is to draw the text on the screen you can skip the bitmap altogether. Depends what you want to do exactly. If you want some pointers what is it you are doing exactly?
