the question says it all, doesn't it? I was just wondering if it was possible to get only the displayed lines of text in a textbox. (Such as line indexes 1-15, to give an example.)

View 6 RepliesI've out an output rich text box called TbxOutput, and I have many different tbxoutput.appendtext("") methods in my program.I don't really know much about how to set rich text box colors, and what I specifically need is for a simple line of code that i can plug in before the tbxoutput.appendtext("" + vbnewline) methods to make that particular line output text of a different color.
For example, when my program normally outputs messages it does it in black, and i want it to remain that way by default. But when it outputs an error message, I want that particular message

I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple
RichTextBox1.LoadFile("C:Documents and SettingsDesktopSigniture.rtf")
I have code that when text fills a main rich textbox beyond the size of its dimensions - the vertical scroll appears and simultaneously vertical scrolls the main rtb and a second subordinate textbox.
If I have a couple lines of text and I scroll down a line(row) of text using the cursor I wish the subordinate rtb respond in the same manner i.e. scrolling down the same line(row) and obviously the lines of text underneath.
I've got myself a CSV file with the following contents:
1,The Compact,1.8GHz,1024MB,160GB,440
2,The Medium,2.4GHz,1024MB,180GB,500
3,The Workhorse,2.4GHz,2048MB,220GB,650
It's a list of computer systems, basically, that the user can purchase.I need to read this file, line-by-line, into an array. Let's call this array csvline().The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on. (I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on.
It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot.So far, I've been able to paste the numbers of each system into an combobox:
Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _
("F:folderprogramnameprogramnameinDebugsystems.csv")
Dim csvalue As String()[code]......
But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message:
"Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'."
If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message:"Error 1 Number of indices is less than the number of dimensions of the indexed array."

Dim name As String[code]............
I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.
On the main form of my application, I have a Rich Text Box which is where the user will be entering information. The text is black. then, i have a button which calls the dialogue "Notes" A dialogue appears, with a rich text box. the user should then be able to enter text into the box, click "OK", and the text entered into the Notes dialogue be inserted to the rich text box on the main form -- with the font colour "Red". The rest of the text in the main rich text box on the main form should remain black.
View 2 RepliesI'm Making a Simple syntax highlighter and I'm Doing the highlighting in the text Changed event of a RTB and for obvious reasons I can't re highlight the whole document each time someone presses a key so i highlight one line each time the text changes. But this creates a Problem. If someone pastes code into the RichTextBox It only highlights the last Line. So is there a way to get if the user typed the text in with his keyboard or pasted it from the clipboard in the text Changed event?

View 5 Replieseveryone! I've been at this for a while, and I'm not sure how this issue can be resolved:I'm working on a project in VB.Net, and I have a form with a rich text box. I have a groupbox with 4 radio buttons inside that are intended to change the font color of the text. Coincidentally, I have to repeat this same functionality for a 2nd set of radio buttons that would change the text font family.
At any rate what I've only been able to do is the following to successfully change the font color of whatever text I highlight in the rich text box:
Private Sub rbtnBlack_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnBlack.CheckedChanged
rtbxTextEditor.SelectionColor = Color.Black
End Sub
Private Sub rbtnRed_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnRed.CheckedChanged
[Code]...
Is there a way that I could write a sub (I'm assuming I would use a sub, since I don't think I need to return anything, thus eliminating the use of a function) that would handle the action of changing the selected text color in the rich text box without having to use a separate sub for each radio button? Mind you, per my teacher's specs, she doesn't use a button handler for any of this.
is it possible to make first 60 characters in a rich text box a different color than the remaining text?
View 25 RepliesI have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

Can I actually do this or will I have to write a dll?
View 1 RepliesI am working on an applictation to scan windows files to check for missing files, i have a couple questions on how to do this.I would like to use the %systemroot%system32 that way that it doesn't matter what drive letter it is, i'm not sure how to do this because when i tried it, it told me the file i was looking for didn't exist (in this case C:windowssystem32 undll32.exe) which does exist. Is there some way to use the %systemroot%?
Also, i am trying to print the resaults to a rich text box such as if rundll32.exe is missing put in the box "rundll32.exe is missing". How do I allow it to write it in the box, I tried the print command, but it didn't work.
I've been wanting to create a look like the attached jpeg Ive been looking around for a few hours for a solution to make text boxes transparent or have a background image. I've found a few projects on this form and elsewhere which include transparent text boxes, but every time I try to use it the way I need to--with the text box over a picture box--there are always various rendering errors. Most of the time, the text box is transparent if its just placed on the form (not over any other controls). But when I place them over other controls (like picture boxes), the 'transparent background' always take on the color of the form background.
This is one that I was trying to use. I found a few others around, but they all had the same render errors more or less.[URL]...I figured transparency or background images would have been supported natively. Anyone have any ideas? Maybe I missed something in my searches. I didn't really see anything which adds background images in text boxes (rich or otherwise). At this point, I'd just like anything that works, so it doesn't really need to have transparency--just a simple background image would be great.
