View 7 RepliesI have the same problem that Niphoet had in this thread: vb .net overwrite a specific line in a text file
I am trying to implement the code that Axarydax showed in C# that I am trying to translate to use into vb.net. My problem is that the code will make my new text file but will not write any of the lines from the other text file to it and just leaves it blank. I think my problem is with the while loop statement but I am not sure.

Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.

I am creating a basic programme in VB as a piece of coursework. Most is going fine however I am having problems saving text to a text file. Let me start by saying I know how to save the text to a text file, but I cannot save it how I want to. as you will see from the code below currently it saves to a file called OrderInfo.txt on the D: drive (which works fine).
However as I will be submitting the code via its VB state (i.e. just in the test mode and not published as an exe or anything) I want the file to save in folder \Assignement\Orders\OrderInfo.txt. I dont want it to be drive specific as I dot know where the lecturer will decide to put the file so it may be on D;, E: C:\Documents and settings etc....
Is there a way I can set it so that it will just look in the local folder where the VB is being run from much like you can with html? So instead of assigning a letter I can just type \Orders\OrderInfo.txt.
Private Sub cmdConfirm_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdConfirm.Click
frmSummary.iOrderNo = frmSummary.iOrderNo + 1
Dim FILE_NAME As String = "D:\OrderInfo.txt"

We have some information that we need to write (about 18KB) to a .txt file stored in one of our network drives. The file is re-written about once every 15 minutes but is read practically at least every second. We are currently using StreamWriter to write file.The file server is in remote location and the round trip ping varies from <1ms to 15ms.
The problem is, sometimes it takes as long as 6 seconds to write the contents to the file, which is definitely way too long even after we take consideration of the network speed. therefore, I am just wondering if there is any efficient way to write the file using VB.Net to improve the performance? Java has a very good tool named BufferedOutputStream, which unfortunately is not available in VB.Net (or I just have not found it).
Application log file have been created to monitor the process and following code has been used to write the log information into text file.

Im working on an assignment for school and i have to write my schedule to a file using input boxes, also i have to use a structured array on the assignment. Both of these i have working fine.I just have one problem, my formatting such like when i write to the file it doesnt look all nice and straight and when i read from the file its uneven also. I know its because the classnames/teachernames are different lengths but i was wondering if anyone could explain to me how to format it to make it look nicer in the text file, and when its displayed on the form in the label

How would a person read a line of a text file by the number of the line. In other words, if I wanted to get the 3rd line of the file, how could I store that third line in a variable. While I'm at it, I might as well also ask how to do the opposite, or write text to a specific line (in this case, writing over the other information on the chosen line).

My application is a text parser that scans a txt file, removes punctuation, and then stores the individual words in another txt file for later analysis. My end aim is to process txt for semantic similarities.
