i just want to ask for a code of this program wherein you will enter a line of text on the text box and you in the label it will appear the set of words you entered and it will count how many tokens you typed..[URL]..
I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt" edit_input = New StreamReader(user_data_file) Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.
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
Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.
A piece of code that will allow the user of my application, to enter the text "unemployed" into a text box and also allow them to enter numbers for how many years the person had been employed for.
i have 2 forms.in form1: i have 1 combobox in form2: i have 1 textbox and 1 button...I want to make in form2 when i enter some text in the textbox and press the button the text to be added in form1 combobox
I'm trying to enter code into a button to save a text file from a text box.The text box is called txtEditor, I have created an open file button using the openFileDialog1 and have been successful with this I just can't get the saveFileDialog1 to work.
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.
I have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.
Problem: When I tick a button I want text in RichTextBox so I Do the following thing: RichBoxText1.Text "text" But I want an extra line with another text so I do RichBoxText1.Text "Text1" But when I click on the button only the latest Wroted text is comming up (Text1).. How can I get more text with this code? I know you can also do just edit but I want add some other things I wroted in a TextBox.
I recently try to make a text editor, but when I try to save what I entered in "RichTextBox1" to a text file, it will save it as a line only.Mean if the "richtextbox1" like this:
QuoteHello World
What the program save for me is like this:
QuoteHelloWorld
This is my code for saving the file:
Dim sfd As New SaveFileDialog sfd.FileName = "" sfd.Filter = "All Files (*.*)|*.*|Batch Files (*.bat;*.cmd)|*.bat;*.cmd|VBscript (*.vbs)|*.vbs" sfd.ShowDialog()
a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.
Private Sub txtMassTrackingNo_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) _ Handles txtMassTrackingNo.TextChanged
I have a couple of VB6 programs which work 100%, however not under W7, so I need to upgrade them to Visual studio 2008 pro which I own a copy of.The VB6 software used to open a file, read in a line of data and process it then save it in a new file, before going on to the next line input.I need to convert this process to VS2008 pro and can't get my head around it..... getting old you see.I also have a few other needs to do with file handling, but I may be able to sort them myself if I get a start with the above problem....
I am trying to get the enter key to invoke an action from in a textbox. I want it to click a button. In Visual Studio 10, which I am using, the is an "Events" selection in theproperties area. Under this there is an "Enter" which allows you to pick something to invoke. So I choose the button that I wish to invoke. However, when this is selected this way, I run the debug and after i type something and hit enter in the text box, nothing happens and I hear a default sound. Why is this not working as it appears it should? What am I not doing right?
I have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.
I must use streamreader to read text file line by line into array.
Here's what I've got.
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click Dim numbers() As Double = New StreamReader(txtfile.Text) Dim numbersarray() As Double
I just joined this forum as I've been looking for a nice and serious VB forum for a long time
I'm having troubles making a program to search a text file line by line for a specific string.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim objReader As New System.IO.StreamReader("C: est.txt")
[Code]...
as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.
now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost
for a "Readnextline" command or something like that?
I have a list of random numbers in my text file.I read it like this.
Dim FILE_NAME As String = "C: est.txt" Dim TextLine As String If System.IO.File.Exists(FILE_NAME) = True Then

under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file
