so i figured out how to save to different lines in a txt file. and how to open it. it opens fine. every label gets the right value, but when i press a "+" button it should add a 1 to it.
e.g: label1 has the value 8 after loading. i press "+" to make it 9. but instead it make label1 to 1. how should i fix that?
here's the [URL]..the code was too long for this forum so i posted the code there.

I am a beginner of VB 2005. I have a few questions on text file editing and hopefully you can point me to the right directions then I can learn more details by myself.

What im try'ing to do is when a ListBox item is selected and the value has been given with a NumericUpDown box and the ''Add to orderlist'' button is clicked that it saved it to a file called "orders.txt", not at startup but when the first order is made.
Some requirements:
U can't order the same thing twice ( only edit it within the editor ).
The "orders.txt" has to open on a TextBox1 at Form2 ( the text editor ).
And the user can only change the order amount in the edit program.
Example:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.Add("7226218; Hemlock; 22.55; 0")

Have it loads it into a text box in the form, to see - but I want another button to randomize all the lines and then show that in the box, and then have a Save button to overwrite the orginal.

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.

View 4 RepliesI 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 know that Deleting a specific line in a sequential text file is impossible but instead copy the needed lines and not copying the unneeded ones to an output file .. killing the old one and renaming the new one with the same.. I can't make this step...
That is my record file
Code:
Input #1, CustomerName, CustomerHomeAddress, CustomerBussAddress, CustomerTel1, CustomerMob1, CustomerID, DateRent, CarRegPin

I made a form that when you put your CustomerID in Text3 Box.. it access the records and make some calculations. now.. The customer will return the car.. Then his data should be deleted.. I want to know how to make that when I enter the CustomerID and press on the Command button .. It copies the other lines to a new output folder and doesn't copy these ... So it appears to be deleted using this way..
what im trying to do and what i have done so far is probably a little backwards not sure sure how to id it any other way.when the user generates an error because a particular file doenst exist ive got my dialoge box to generate an .txt file for each file it errors on, so that the administrator can check and update missing files as an when - shouldnt be many files missing in the first place, should just be new product ranges or item just launched.what im stuck on is:
1. is there a better way
2. how do i open a .txt file and add the extra lines to it, so i re use the file but keeping the previous data.
The code below opens a file in Example 1 and writes on another file only the lines that satisfy the condition If times > 4 to another file. What I want to do is illustrated in example 2

I am attempting to write a playlist for my media player which is already built. I have found a way to build a playlist for it but it would be helpful if I could save the contents of TextBox1 to a text file without using the save as. I am trying to get over a user inputting a file name for the finished text file so is it possible to write the file c: est.txt without using the save as dialog? I have found that I can use a vbs program file which creates a playlist in a folder. I save the vbs file text to the textbox then save it as a vbs file in the playlist directory, then execute the finished file to make the playlist.
View 5 RepliesI have researched the net, youtube, and the msdn DB, and still can not find the working answer I am looking for.

I know how to hardcode a savepoint in, but since there will be multiple users I would like the option to be up to the end-user.
