I have a .txt file, with five columns - each column is seperated by a space " "
What I'm trying to do is, 1, Add column headers and 2, align the columns to make them look presentable.
For the first part all I know is how to append lines to a text file, my problem is that whenever I append to the textfile it always gets appended to the bottom.
Using SW As New IO.StreamWriter("d:\temp\test.txt", True)
SW.WriteLine("The Headers Should Go Here")
End Using
I have to create a textbox which will list down one column of datas from textfile which is separate by delimiters.But as I have to filter alt.Row from the text file, what can i do?
I'm trying to write a jukebox application as part of my undergraduate coursework at university, and have hit a brick wall. Using while loops, I'm trying to display tracks/songs under particular genres, as listed in a simple text file, from which the programme reads.The issue is, although I can get the columns to be named after the appropriate genres, as stated in the text file, the songs are read, and placed in the first column, regardless. I can't seem to get them to move to the next column, when the previous genre is finished.[code]
I have a program that searches a textfile for whatever I wrote in the textbox. If he finds it I want it to insert into label1 the text that's on the same row as the word I searched for but only the sentence between column 2 and 14 on that row.
I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???
Dim pathdir As String = "C:workingdir est.txt" If System.IO.File.Exists(pathdir) = True Then Dim objWriter As New StreamWriter(pathdir)
I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have
I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.
I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.
I wonder if anyone knows a macro developed in Visual Basic to separate the first part "F-001" to a different column example:
Column A = F001 Column B = Sep138-13, 8kV
The spreadsheet is quite wide, going up to about F-220 I could only get to it:
StringElement Function (str As String, chr As String, ind As Integer) As Variant Dim arr_str arr_str = Split (str, chr) StringElement arr_str = (ind - 1) end Function
is very simple, just separates into single column and not the entire worksheet?
I have a few forms that have a lot of really intensive updating along with a great deal of user interface (text boxes, button clicking etc) Is it possible to open a separate form as a separate UI thread from the start up form that called it to "show" or open or whatever the new method might be?

just another little problem here! Trying to write a quiz for a college portfolio and having trouble with writing to a .txt textfile. On one form(form4.vb), I have a listbox that picks up the information held within a notepad textfile called "usernames" which contains names of quiz users. When written in manually to this textfile, my listbox picks it up fine, however, on a different form(form3.vb), I have a textbox where a user inputs their name, this is supposed to go to the "usernames.txt" textfile to be picked up by the listbox on the other form but instead, it does not write anything at all and if there is already text on this textfile, it wipes it all out.I also have to use the application.startup path instead of the usual C:my documentents etc so i would have to begin with something like this: (Note: code is a little mixed up due to messing around with different variations but this is just a example)
Private Sub btnOk_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOk.Click Me.SaveData("testing")

I have a textfile with timestamps and the amount of minutes my machine has run.
To keep the size of the file in check, I would like to delete the first half of the text file, once the textfile exceeds 1 MB... I have a check in place to determine the file size.
What is the best way to go about deleting the first half of my textfile log?
Do you recommend storing the second half in a temp file, and transfering it to the original log?
Is there a simple way to remove the first few lines of a textfile?
I'm building a program to read a text file and display and find the min and max values within the textfile and display them in text boxes (txtMac, TxtMin) for the user. The program also needs to count the number of items in the text file and put the number in a textbox called count.
So far i've made the code to find the max value (below) but have no idea how to get min value and count.
I'm making a personal program (So it doesn't have to look nice or be super sleek) that is basically an alarm clock. I set the time and date, it writes it to a text document then it reads it from the text document back into another textbox that is hidden and compares it to label1.text which is my system time and date.the problem is, I have it so that I can add multiple dates in one document so when I enter one it'll do as so [code]how can I make the program read 1 line, wait for it to match the label, (I already make it display a message box) and then after that is all done, go to the next line and wait for it to match. etc etc.
I'm making a function that is supposed to delete a line from a textfile "test.txt". I'm having no problems with finding what line i want to delete. The basic idea is this: read the whole file with streamreaderdelete the linerewrite the file with streamwriter. My problem is the last, how can i completely remove the file content, and write another string in it, writer.writeline just appends a line.
