I save data from datagridview to text file. I also load the same data from text file into datagridview for edit and update the same thing to text file. Let say this text file i called as Drill.txt. I have another text file called header.txt which need to match its value with the value of Drill.txt file then overwrite value from Drill.txt to header.txt. Now i want to make my Drill.txt in encrypted format to prevent anyone to open that file and modify out of program. They only can modify it through the program

I have a question because in my I.O.File. I use this to save the data in the listview in a c: est.txt but the problem is that it only save one data and every time I click the save the previous data that I save is deleted and it change the new one that I save. And also when I click the remove in the listview it will also delete the data that save in the c: est.txt and the format should like this
First name | lastname | address |
rae alanah new york
john smith los angeles
Here the code that I did...
Dim myFile As String = "C: est.txt" '//file location
System.IO.File.WriteAllText(myFile, TextBox1.Text & " " & ComboBox1.Text & " " & TextBox4.Text & " " & ComboBox2.Text & " " & TextBox3.Text & " " & TextBox2.Text & " " & TextBox5.Text)
Or you can also create new code base on ur understanding. This is the first time I use the I.O file or file stream in vb.net because my crystal report does not detect my database that's why I need to do this.

I'd like to save data to a text file on a remote server I have. There are no security issues here, just the method.
Dim FILE_NAME As String = "123.456.789.012/variables.txt"
If System.IO.File.Exists(FILE_NAME) = True Then
Dim objWriter As New System.IO.StreamWriter(FILE_NAME)
[Code].....
I know it's not the most secure way of doing things, but the end data has to be in the txt format, otherwise I'd have used MySQL.
Im new here and hoping that I post this in the right forum. I am SLOWLY learning VB, and have run into a problem that I cant figure out.

I am making a small tool that require some calculation. I am using hashtable to store values that I need to calculate. This tool continuously extract data on specific time interval(30 seconds) from webpage and add those data into the hashtable. Now the problem is I need to store the previous extraction data and when new extraction occurs, I need to deduct the previous data from new data.
[Code]...
On first run it shows the result of Data3 = 100 which is currect. But on second run I need to redefine the value of Data2 = Data1 . So I need a result of Data3 = 0 on second run. This may not be the proper way to do this sort of operation. I have also tried using listbox, listview and even textfile to store the Data2 and recall that on second run. But could not make it possible.
This is the last phase of my tool and I am stuck with it.

I have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:
Phillip Frank
3/19/1990
3
999-555-8618[code].......
I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.
how to save data (for example some text that user type [as password etc]) and save that password on same location where is application. After saving I want to have also Load option so we can load saved data.
View 7 RepliesI have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.
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.
View 3 RepliesI have to save the text boxe values of a form to a text file almost like a data record. I will be saving an Employee First Name, Last Name, Dept Number, and Phone Number. This I know how to do using streamwriter.
next form which we have to use stream reader to load one record at a time. The form has a next button to load the next record. How do I seperate each record (I am sorry for calling it a record if this is inappropriate) when use streamreader and how do I load a record at a time.
I know how to open a file and use streamreader, I just don't know how to read one record at a time and move to the next one.
I need to to able to save multiple text-boxes and a combo-box to a text file. the thing is, when I go to save, I check out the .txt file manually and its saved all in one line, no spaces. when I go to "read" it with the 2nd part (<-----this is a 2 part Challenge) it even reads all from that one line in the text file. What i'm asking is how can I make my text-boxes saved in the text file on different lines. [Code]
