The length of the previous words is exactly the same but the "truth length" it is not. I want to know if there is any way to find the truth length of a text string with different fonts The reason why I want the "truth length" is I want to make an rss scroll bar and when the first label "hiding all" in the right to send the next rss it in the left.

what is the code for finding the shortest,average and longest sentence form the text box
View 4 RepliesI need to go line by line through a text file as well as a listbox and remove lines over x amount of characters as well as adding the number of skipped lines to a label. I am trying to use a listbox in this example but it is not working correctly. What I am I doing wrong? First it will only remove an item when it is highlighted (focused) how can I make it so that is not required?[code]...
View 7 RepliesIs there any function similar to string range in vb.net 2.0? What I am try to achieve here is to extract some text from a string with unknown length. eg. given string = text text text mytext1 text text text text mytext2 text text text text expected string = mytext1 text text text text mytext2 So I have the indexes for "mytext1" and "mytext2". I am looking for a way to get the text that wrapped in between those two strings or indexes.

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.

How can I find out the length of particular row of array?
Label1.Text = array.Length
This shows the length of whole array.
e.g. 30
0 1 2 3 4 5 6 7 8 9
0 1 2 3 4 5 6 7 8 9
0 1 2 3 4 5 6 7 8 9
I would like to get the length of 0 row.
0 1 2 3 4 5 6 7 8 9

I was just adding some neat features to my program, and now I realize that they've caused problems with my formatting features. In my program, you can bold, underline, italicize, and strikethrough the text you select. You can also change the color and font of the text. After adding in the ability to change the font of the selected text, I noticed that there was a problem when you tried highlighting the entire word, with some characters in the word having different fonts, and then formatting (bolding, underlining, etc.) the text. The error I get is[code]...
Notice how the "Ma" is in the Comic Sans MS font and that the "th" is in the Arial font. If I were to highlight this word on my program and try bolding it, the error would pop up.
Anyone can give the coding for finding the longest & average length?(displayed in a messagebox)

I just started with VB.net yesterday I want to search through a text string, and then count how many times a word appears. How do i do this? Is there some sort of function that i can use together with a loop of a kind?Something like the inStr(), just something i can use with mulitble appearences!
View 4 RepliesI have to find a string in a huge text file ( ~ 50MB) and then replace it.Since it's quite huge I tend to open the file and then read line by line, and then replace the necessary line(s) (rather than "readall" the file of course).My question is how to replace the whole line?Let's say I found the line that should be replaced . I know I can create a copy file and copy all lines into there ... but I'd prefer to replace the line in the original file rather than creating a copy instance.

I would like to step through each *.txt file in a given directory, open it, find and replace all, perhaps a thousand, occurances of a given string (e.g. "00/00/00"), then close and save file, and step to next one in the directory to do the same find and replace. I've been looking at filestream classes and regular expressions but don't see a clear way to do this.

View 3 RepliesUsing XP and VB 2008 Express for development of Widows Forms App.I am setting a button's .text to "" and then assigning a bitmap with some text written on it to the button's .image. Everything looks great on the development compter, but is almost unreadable on test computers using Vista and Windows 7. This despite trying a number of different combinations of (standard?) font family and size (including Arial, Verdana, Microsoft Sans Serif). Why?
Details....I have a button on a form (32 pixels x 32 pixels).I set the button.text field to "". I create a bitmap a little smaller than the button, and DrawText on it (I can't simply use the button.text field because I want to place text in different areas of the button and draw special characters.I use the following code to create the bitmap:
m_bmpDrawingSurface = New Bitmap(30, 30, Drawing.Imaging.PixelFormat.Format32bppArgb)
Dim objGraphics As Graphics
objGraphics = Graphics.FromImage(m_bmpDrawingSurface)[code]...
I wonder if somehow fonts are being anti-aliased or otherwise cleaned up by the system on the development computer, but not on the other computers. I also wonder if I should be creating just a simple 30 pixel x 30 pixel bitmaps, or perhaps should be trying somehow to get the buttons 'device context' or something. Or, is there an alternative to DrawString that draws text more intelligently than just setting the nearest pixel either black or transparent, which is what seems to be happening (ie, no anti-aliasing or creation of shades of gray). Maybe another pen? Is there an "anti-aliasing" pen?

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

I'm working on a program (Under Visual Basic .NET 2008) that draws text on a PictureBox using a font that is already installed (registered) in system fonts. I'm wondering how can I perform the same but with a font that is not already installed on system, by adding this font file (*.ttf usually) to my solution explorer and use it in my program, given that this font file must be included in exe file.
