View 1 RepliesI ran into another speedbump with loading a rich text format file to a rich text box. In the program the text file is supposed to load when an listbox item is clicked. I believe that the code is correct, however, the file is not loading or not displaying. After the code was changed to this I saved the program and moved it do the approperate directory and added RFT Troubleshooting Docs folder. Running Visual Basic Studio 2008.
Private Sub btnOne_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOne.Click
lstOne.Items.Add("Template")

visual basic 2008
I am pretty good with visual basic and visual studio, but the one problem I have is saving... I am currently creating a game, and it has a lot of variables, I want o be able to save all those variables to a text file and then re-open it later. When it is open, i want the variables to have the original value from the text document.
To sum it up: I need variables to be saved in a text file, and then be able to open the text file back and have the variables have the proper values from the text file.
I have been searching around google, and I found ideas, but I have no idea how to use them. Like using XML or saving a table with " TextFile.WriteFromTable" "TextFile.ReadToTable" but I don't exactly get how to use those (the posts weren't too clear)

I'm having a problem with loading two text boxes from a saved text file. I've built a log in form that saves the user-name and password on separate lines in a text file.I have a save button and a load button. My problem is that I'm new to Visual Basics and I can't figure out how to get the two lines from the file to load into their separate boxes on the form.The code that I have loads both lines from the text file into the User Name Box.Oh the username is on the first line in the text file, and the password is on the second line of the text file. Could someone please help! My Loading code is:
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click
If File.Exists("Login Config.txt") Then
Dim ioFile As New StreamReader("Login Config.txt")
Dim ioLine As String ' Going to hold one line at a time

I am trying to create a program which reads data from a text file and insert the data in to a SQL 2005 table, but unfortunately it only reads the first line and insert correctly but not the rest of the lines on the text file
The text file looks like this

Micke, Gulm, 39, 07/08/1970

sort out this issue as I need read the entire text file which in reality will be about 5000-10000 lines and insert them in to the SQL DB line by line.

View 11 RepliesI made a text file (.txt) in my project by going to Add New Item and then Text File. I want to have my text file be loaded into the rich text box i have on my form but it doesn't work. It says it can find the file. This is my code:

I am new here and just started visual basic 2008. I want to load a BIG file to edit the text. It is 24MB So whenever I load it in the richtextbox it shows : 7@
:/ Regular text files load fine.
Here is the
CommonDialog1Open.Filter = ("EXE [*.exe*]|*.exe|All Files [*.*]|*.*")
CommonDialog1Open.ShowDialog()
rt1.Text = (My.Computer.FileSystem.ReadAllText(CommonDialog1Open.FileName))
I know I am trying to load .exe! It will load if I save it through the program but will only show 7@.
So i have a text file that is created in the program which can be loaded back into the program(game save)
Whatever is in the text file "stats" should be listed in listbox1 in the same order it is in the text file. The same with "items" in listbox2. And then "quests" will be in listbox3.
The problem is when i load it instead of what is in the text file it says...
note that box3 is correct that it has nothing in it.

Getting a vibe that my VB is cursed. All I want to do is load a textfile and have the text appear in TextBox1 But no. I have looked at 3 different tutorials and I have tried copying their code word to word but still!
