Determine The Length Of A String To Print Using PrintDocument
Oct 19, 2010
Do you know of a way of knowing the lenght a string will ocupy on a .DrawString using PrintDocument?
What I want to do is to break up a string in case it won't fit on the page, do not sugest to search for the lenght of the string itself because I am not interested in the number of characters, as you may know, PrintDocument "draws" the text on the page so on proportionate fonts, the number of characters is independent on the lenght of the output.
this is the line that prints the text:
vb.net
e.Graphics.DrawString(strText, New Font("Arial", 12), Brushes.Black, 10,10)
Of course I could use monospaced fonts like courier or the like but... well, I don't want to.

I am trying to determine the length of a string in pixels.
I created a little test program for myself and placed three labels on it, each with the same font in a different size. I set the width of the label to 1024, the screenwidth. I used the same test text for each label, cutting it off at the last character that shows, so there is not hidden text running off the label to be included in the string width count.
What I have found is that the width of the string is being reported as wider than the label, even though, as I just mentioned, there are no characters running off the edge of the label. So, something's awry. Does anyone know how to get an accurate width?
Here follows the whole test code. You can drop three labels on a form and run it to see what I mean.
Code:
Option Explicit On
Option Strict On
Public Class frmMain

I try to determine the lenght of a string variable, but get the wrong outcome when using: testje = Len(testSTR). When I insert the following line of code: testje = testSTR.Length the answer is still wrong but when I click "Length" I see the correct value. How to get at that value, so I can use it?

When I print to the printer, using the PrintDocument, I want it to be able to throw an exception if there is a problem. Currently, if I print to a printer that has a jam, is offline, or doesn't even exist, VB still thinks it printed fine. I never get an error. How can I have the printer report back to my program so that if I print to a printer that doesn't even exist, it wont let me do it? I just tried adding a LPT1 printer to my computer (and there is no local printer). I called it some random printer and installed some random driver. Then used my program to print to that printer and never got an error.

determine the length of the value/string returned from a regular expression and convert it to a different string layout Alternate:replace the . with a / in the regular expression?replace a character with another character in a regular expression AND determine the length of that expression to replace it with a string output using that regular expression?IE if the regular expression returns 3.0.4.u1, i need this to read c3/0/4 up 1 instead.Below is the code I have so far (cut from the total program)
' original text
Dim myText As String = rawData
' capture the interface pattern (first # in string)
Dim interfaceUS As String = "s(d.d.d.ud)|(d.d.ud)"

This is a scratchy rough copy (Published as Version 1.1.0 because there was a huge logic error in 1.0.0), and I was wondering if anyone could give me pointers on how to make the code better. The heart of the program is here. I don't have the code for the SplashScreen, AboutBox, and the InstructionsForm because that is unnecessary. The main issue that I have is with the large EndSalesButton_Click event. The big block there is driving my eyes and brain crazy while trying to test the logic. So, to sum up everything, can anyone make that look nicer and easier on the mind? If you would like to run my program to better understand how it works, feel free to contact me at either of the two emails in the beginning declarations (lines 2 and 3)of the code below.

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.

I'm writing some code that takes a report from the mainframe and converts it to a spreadsheet. They can't edit the code on the MF to give me a delimited file, so I'm stuck dealing with it as fixed width. It's working okay now, but I need to get it more stable before I release it for testing. My problem is that in any given line of data, say it could have three columns of numbers, each five chars wide at positions 10, 16, and 22. If on this one particular row, there's no data for the last two cols, it won't be padded with spaces; rather, the length of the string will be only 14. So, I can't just blindly have

But for some reason if there is no file in the current folder it will not go to the windowsmedia folder, do I have something wrong?

I've created some classes that will be used to provide data to stored procedures in my database. The varchar parameters in the stored procs have length specifications (e.g. varchar(6) and I'd like to validate the length of all string properties before passing them on to the stored procedures.
Is there a simple, declarative way to do this?
I have two conceptual ideas so far:
Attributes
public class MyDataClass
{
[MaxStringLength = 50]
[Code]....
This seems like a lot of work and will really make my currently-simple classes look pretty ugly, but I suppose it will get the job done. It will also take a lot of copying and pasting to get this right.

I am working on a program that will take in a string of length 7 containing either R,G or B for the colours. The program will then check that the string if 7 in length and if it contains any other characters than R, G or B then it will be invalid. I created this code but when I enter the right string length and characters it always gives me the error for not having the right string length.
