I want to create and write to a text file upon Program Load...this is my code (does not work):
Dim path As String = "C:Documents and SettingsAll UsersDocumentsThe Bible Study Tool est.txt"
My.Computer.FileSystem.CreateDirectory(path)
'create and write to settings file

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 to use a file named Colors.txt
CODE:
So when i click btnNextRecord i need it to show data for first employee when i click btnNextRecord move to the second one and so on. But when i click btnNextRecord it only displays data for last Employee and if i keep clicking it, it will keep displaying the same data for the same amount of employees i had entered data for.

I am making a program that loads, edits and saves 5000 rows x 100 columns of data. The data is stored in a datagridview. I use these commands to write the file:
dim z as integer
dim z1 as integer
fileopen(1,"c:drawermyfile.txt",openmode.output)
for z=0 to datagridview1.rows.count-1
[Code] .....
Every time I issue this command the whole program freezes until the computer is done writing the file. Is there some way I can get it to write this file without freezing up the program? Or, perhaps a better way to write this large data file?
All the code i found for multi-threading is complex and not clear.What i want to do is creating a thread for reading and analyzing a big text file on Form_Load event, so that the form UI building continue without waiting for reading and analyzing the file finish.
View 2 RepliesI've been staring at my code for a few hours, and cannot think of the next part.For my final I need to make a hangman program Pretty much I have a button to load a .txt, a label, a multiline textbox(which will be hidden later), and a normal textbox. I need the program to load the txt file, and randomly select a word. Then have the program put a " - " for every letter in that word The program loads the txt file,to the multiline textbox,but I don't know what to put next. EDIT:After looking at my book i noticed it shows how to make a hangman program, but without loading a text file. So, all I need is the code that will make it select a word randomly from the list, and i think I can do the rest..

View 1 RepliesIm having trouble creating and then writing to a file. First, I check to see if the file exists, if it does not, then I create the file, close it, and then open again for appending text. I am getting an error during debugging saying the file is in use by another process, which is confusing since I am closing the file before opening it to append any further text. Here is my code:

I am trying to create a countdown to a date that the user can enter. I think I got most of the code in the button that saves the date. It gets the date the user entered in comboboxes, creates a txt file, then writes all the information to that txt file. I tested it out, but it didn't work. It created the file, but when it tried to write to it, it errored. The error says "The process cannot access the file 'C:Countdown.txt' because it is being used by another process." This is the code.

I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.
View 14 RepliesI'm making my own ToDo program, and I need to add the ability for the user to create a ToDo item. When they do this, I need to be able to add in an XML element/section in a list file.My XML file looks like this:

<list>
<item>[code].....
Say if a user created an item with the name 'papers' and due date 'Tomorrow', I need to be able to make another list element like above and insert it before the </list> tag. Basically I'm asking how can I write to my XML file at a specific position (at the end before the </list> tag)? Is it possible just to go to the end of the file and go back a line?

View 5 RepliesI am building an application that accepts input entered into textboxes, then checks the input for negative values, etc. before writing it to a file. If the data does not meet the conditions, a message box pops up letting the user know.

How do I make it only write to the file if all the data meets my conditions?

Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt")
Dim dFiles As IO.FileInfo

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.
