I would like it to check if the text file (myfile.txt) contains anything. [Code] but if I changed the myfile.txt with a value of "hello" and save it. I still get the "msgbox("myfile.txt does not contain any information")" What am I doing wrong?
View 24 RepliesI have a text file with user names in them on separate lines. I want to check to see if any of the lines doesn't match the exact text im checking for. It doesn't matter what line the text is on, as long as it is in there. If it's not, alert me. Previously i tried .contains() but obviously if a user name is "hello" and another's is "helloworld" it will match both of them.So basically i need to read all the lines in the txt file and if none of them lines contains the specific text im looking for then alert me.

View 1 RepliesI'm making a program in which a couple of txt files will be used for reading and writing (streamreader/writer). Incidentally, these txt files might be in use by another program, although never more than 1 or 2 seconds each time.
Suppose, I have the following
Dim Input As New System.IO.StreamReader("c:data.txt")
Data = Input.ReadLine
...more code...
[Code].....
This doesn't work though. When I open c:data.txt in another process and run my VB application, I still get the IOException.
I'm trying to make a small program that will check if the lines repeat.

I'm trying to make my app check for updates by reading a text file and comparing it to a 'currentversion' setting in my application (or if checking the executable file version is easy, that would be good).
Here are the basic steps: -Read text file hosted on [URL]..-Check if the version number (eg '1.1') is higher than the number in the 'currentversion' setting or the executable file version (whichever is easier).
-If the text file version number is the same, change form background colour to green, if it is higher, change the background colour to red.

i'm working in VB.net to create a program that checks the text in a remote text/html file against a local text file, and if the do not match, the program then does something. I keep getting an exception and i can't figure it out.

I'm not at all used to working in VB, and i'm not sure if i did that HTML right either, so that could be the problem.
The only logical way is reading the file and creating Try and Catch?
View 4 RepliesIts been requested that my project has a way to limit number of users logged in at one time. I have that figured out but there is a problem. What I have done is that when a user logins in the application creates a .usr file in a directory on the network. If the number of users (value in the database) is less than the number of .usr files another user can log in, otherwise they can not(the file gets deleted at logout or application close). Now the problem is I need to create a way that if the .usr file get deleted the application will close. Is there a way to keep a watch on file and if it gets removed close the application.

I have a text file with some call records in it. Each call record states a line in that text file. And what I want to do is that parsing to database with a 100% success rate. Due to sometimes the SQL connection might get buggy or stop or w/e so it came to my mind that I should make some function or maybe a stored procedure to check whether the requested/selected or whole lines in that text file have been successfully added or not to the database. Let's assume I have 10 lines in a text file called "log.txt" like:
call line 1
call line 2
call line 3
call line 4
[code]....
And assuming that the SQL connection to the database got stuck somehow(buggy) and it stopped inserting those lines to their respectively columns. Let's say it parsed lines from 1-6 and it stopped there, that's where I need the app to tell me that it stopped and continue inserting immediately where it stopped at to the end from 6-10th line. What am I supposed to do? The smoothest way so that the processor doesn't get overwhelmed (in case there are like hundreds of thousands lines). And should it be written in SQL as a stored procedure or written as a function from VB side.Toolkit : Microsoft Visual Studio 2010 Ultimate - VB.Net language & Microsoft SQL Management Studio 2005 - SQL Database.
Having no real experience with updater-style applications, basically I want a secondary EXE to be bundled with my application which will update the program file. Its a one file application - so its a simple process. Its just for the PC's inside the business.Currently, I think it will be easiest to get the updater to check a text file uploaded onto our server, and determine whether the running version number is above or below that. The new application will then be downloaded from a simple http link.
-I have an interface designed, so that will be attached to my request.
-Is it possible for the updater to update itself? How could I request that?
-Is there any way I can ask that the link which the updated file will be downloaded from is definitely hidden from the user?
-Will the developer incorporate error handling for if the program is running when the updater runs? How do I ask for that?
Is there a better way for the updating process to run? What other things should I ask the developer to include?
Is it possible to check a location for a file and if a file exists then create a new file (+1) in the file name? For example if there is no test file in the C:Temp folder then create a test.txt file and if there is one there then create C:Temp est1.txt and if there is a C:Temp est1.txt file then create C:Temp est2.txt and so on?
I was thinking
If Not IO.File.Exists("C:Temp est.txt") Then
IO.File.WriteAllLines("C:Temp est.txt" + 1, vbCrLf)
End If

Im trying to make a program which would check for users from text file on a certain website I can populate the list box, and loop through it's items here is the code i came up with so far and it doesnt work properly, it pops out first item in the listbox, and last item only, even though that they shouldnt be popped out
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
If Not ListBox1.Items.Count < 2 Then

(this is supposed to check every user, and if user doesnt exist, website will return page not found, else user exists and his name is added to listbox2)
I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.
How do you pick a random piece of text from a text file in this manner....

I need to pick a random answer, not including the question. let it be the simplest solution. I am only a beginner.
My application is like this : i have to search my data from database with some check box and text box when user select check box specific function go on and then when user enters some range of value in textbox then the result will shown in data grid view after that i can print it by selecting data

Imports System.Data.SqlClient
Public Class XtraForm1

I m also pasting the demo picture.
I first want my program to get the text from a text file(I know how that's done), but once it gets it, I want to somehow save it that it won't need to get the text again(for example, if you restart the application, it won't need to get the text from the file because the text is already saved).
