I am new to VB.net
I have a simple form with two textboxes, I want Textbox1 to write to a file named C:VALUE1.txt and
Textbox2 to write its value to a file named C:VALUE2.txt
Any text that is already in the text file MUST be over written.
I have a small database from which I need to select specific data for my Windows Form Textbox.I have a table in a database with a few columns: "ID,Date,Val1,Vla2,Val3,OK" (int, date, int, int, int, bool). There are several rows, but only one of the rows has the boolean value as 1 (or 'True').I would like to select all of the information from that row and write it to different TextBoxes.[code]

View 9 RepliesReading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?
I've been asked to re-write an application that was written sometime ago by another programmer. This application reads data from a database table, massages it, and then writes out the results to a text file that is later shipped off to another company. When I run my new application, it generates a file that, according to the byte count, is twice the size of the file output from the old application. However, to look at the two files with note-pad they look identical. I found that by using 'Ultra-edit' that the new records have a low-value byte hex '00' between each real character.
View 4 RepliesI need to write values, mostly doubles into a text file in VB.NET. I ported the code from VB6, but the performance of the VB6 write#fileID, vars) in VB.NET, is very bad, it introduces a delay of about one hour. I have tried out the streamwrite, and its performance is good; it's actually faster than VB6 write.
I am using the write(string) method for the streamwriter, and I am concatenating the values using variable names as follows: streamwriter.write(var1 &","& var2 &","&....&","& var n &","). This version of write enables me to have more than one variable written to file per statement. The problem that I have is that the content of the file is incorrect, unlike the one produced by the slow VB6 write in VB.NET.
Is there a better way of achieving this requirement; preferably using the streamwriter? I cannot use the streamwriter.write(double), becuase I'll have to use multiple lines as I am writing about 800 vars in convergence test loops resulting in a total of just over 2 million writes.

I'm trying to write a program that detects the contents inside a textbox, and if empty displays a warning, and does not input anything into a rich text box. However, if something is detected, it would not display the warning and input the textbox's text into the rtb.

Been trying to get somewhere with this in another thread, but no such look, just keep getting reffered back to the same documentation... If I understood the documentation, I would have fixed it by now:

View 3 RepliesI tried to write a text written in my textbox to file.(a .txt). I scanned it to see if it contained any illegal characters, the program said that it did not. However, when I went to save it it said that the program performed an illegal operation.

It created the text file but did not write the content of the textbox to the file.I can save the text in Microsoft word without a problem. Is there something wrong with the encoding for the textbox and how do I set the encoding for the characters so I can write it to a text file.
