I am looking to add individual lines of user inputed text into a rich text box. I've been working with .text and .appendtext however I can't assign individual lines of text.[code]...
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.)
I'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 2 panels set up, one contains the rich text box the other one contains a single label. The am currently using the following code however it is not working.
Dim line_count As Integer = mainEditor.Lines.Length Dim linecounter As Integer = line_count linecounter += 1 line_count = 0
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.
How can I pull individual lines out of a multiline textbox when wordwrap=true?
For example I have a long string in a textbox and it wordwraps to create 3 seperate lines. How can I get the text of the 2nd line? The control thinks that there is only 1 line since it wordwrapped and there are no CRLFs in the string.
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

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 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.
I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then EnglishForm.Show() ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
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.
I'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?
So I have a code atm that has 2 combo boxes, one to select the make, then it will enable the model, I have 3 model choices, here's code: [code] Once I have selected my model of the car, it takes me to that specific form with a picture of that model, I then want to display individual parts, with individual prices that will add up in a text box above.
everyone! 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.
I'm not getting this at all I suppose. I've tried so many variations to split the lines into individual fields and I still cannot get it to do what I want.
I have to get lines from a sequential file which read like:
CODE:
And load them to a listbox like this:
CODE:
With the ID # padleft(10, "0") and the commas eliminated, and only the Last Name, First Name and Middle Initial showing.
This is my mess of a code (it is just one of many variations)
CODE:
I've got the ID field right but the rest just shows up as it is in the file commas and all.
I 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.
I will show 3 columns of text in rich text box. i want show the column border with color.i can separate the texts with tabs or spaces but showing data in columns and cells will improve the visual of my program .
Okay, so what I want to do is directly output formatted RTF text to a Rich Text Box control in VB.NET. I don't want to find the text, select it and color it as it is not practical for what I'm doing. I've tried outputting RTF code but that isn't working either. Can I actually do this or will I have to write a dll?
I 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.
I have an SQL database, and 50 text files, and Visual Basic 2010 Premimum,I need to find a specific line of text in the text files and then take the next 37 lines of text and save them in my database. I need advice as to point me in the right direction
