I 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]...
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
I want to remove all the line which contain [Txxxxx..] and place it in another file. i want to be do like cut and past. Is that possible. Can we remove lines in text files?
I am trying to automate the removal of lines in a text box with no characters or numbers. I have the following code, but it is not working.
Code: Private Sub RemoveBlankToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RemoveBlankToolStripMenuItem.Click Dim tmp() As String = RTB_01.Text.Split(CChar(vbNewLine))
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.
remove blank lines from listbox?And remove specified text from listbox (text line that i can specify in form code(But if i specify to remove line something like [URL] it will remove the line [URL] but doesn't remove line [URL].
My code for adding items to listbox is:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim PageElements As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("img") For Each CurElement As HtmlElement In PageElements
I have a text file that I'm reading into a listbox. I want to skip a line if it's blank. The following code works if I leave out the check for the line being blank. It puts the file in the listbox with no errors. However, when I include the If statement that checks for the line being blank, I get an ArgumentNullException in the Items.Add line when It gets to the end of the file.
'Read Multiline File Dim FILE_NAME As String = "C: empliz-etsy.txt" ' If System.IO.File.Exists(FILE_NAME) = True Then
I'm trying to remove the first and last lines from a text file. Obviously the last line will be at an undetermined position (i.e. line 50 or 5000). I couldn't figure how to remove the lines, so I wrote code that would rewrite every other line:
I know it may be quite easily for you. i have a text which contains 40 lines, I want to remove lines which starts with a constant text. check below data.
When I used (?mn)[+CMGL:].*($) it removes the whole text , when I use (?mn)[+CMGL:].*( ) , it only leaves the first line. +CMGL: 0,1,,159 07910201956905F0440B910201532762F20008709021225282808 +CMGL: 1,1,,159
I have a program that will read a text file and put information from the text file into multiple text boxes. What I am trying to do now is be able to change the values in the textboxes and be able to write the specifc changes back to the text file. One way I though of doing that was using a while loop and copy the lines of the text file to another text file, then when it finds the line that has the specific change from the text box, make the change and continue writing the line until it reaches the end of the file. Then I was going to copy the file and overwrite the original, escientally making the change to the new file. Right now it will make the new file but will just make a blank text file. I think the problem is in the while loop statement but I am not sure. Here is the code below:
Code: Private Sub submitButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles submitButton.Click Dim trackname As String
I was working on editing a code for a simple text program, but when running the program for multiple lines, the text being read gets too long or too many lines, the computer slows down alot and almost stops functioning. I am using standard integers like document.lines.length or listbox.lines.count. I think these are standard integers and I need to know how to enable them as Long of Float Integers.
I'm assuming I just change Dim X as integer to Dim X as long or Dim X as int16
But I'm not sure as everytime I change something I get cannot convert to double. The code I'm interested in changing is ... For i As Int16 = 0 To ListBox1.Items.Count - 2
The list box will only get to about 3000 items or so. and For iPos = 1 To xy If Mid(sString, iPos, Len(Text1)) = Text1 Or Mid(sString, iPos, Len(Text2)) = Text2 Then JJ = TextBox1.GetLineFromCharIndex(iPos) This read box will read documents above 32,000 lines, which is the reason for not wanting to use Integer.
I have a notify icon and I use the 'Text' property instead of 'BallonTipText' because I just like it better and it fits well with my application. The only thing wrong with that is the 64 character limit. How can I determine the length of a string, remove all characters after the 61st character, then add three periods at the end of the new string? I've looked around and can't find any solution to removing all characters after the first X characters.
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 have an array in my application and I don't know how many values there will be in the array because it gets the data from a webpage. Filling the array with information from the webpage works except for the length, it always returns 999. This is my dim Array() as string Array = GBA(source, "<b>", "</b>") Count = Ubound(Array) How can I find out the length of my array?
So me and a friend started a project in school and we decided that i'll do most of the design part and he'll do most of the coding. I wanted to change the design on my buttons and changed the button image background and changed flatstyle to flat. Now there's this thin white line around every button instead. how can i get rid of it? Check attachment.
