Jun 9, 2010
I am making a program that reads a file. Csv,and information to a textbox.
After he demand on the Csv file, the same information he writes what is in the same row forward in the same textbox.
A-dos-Francos;39.346246,-9.031105
A-dos-Negros No;39.366089,-9.090929
A-dos-Negros PV;39.366886,-9.131098
[CODE]...
Example: If "A-dos-Francos" is written in the textbox I want that it be replaced by "39.346246,-9.031105"
But in the same textbox.

I have to make a program that reads a txt file after reading it, show it in a richtext box and in another tab make the average of the grades the input received sort it by the student id and then in the same rtb sort it by the average of their grades, and finally save it on a new text file.
The text file input is something like this
12 3 10.0 6.9 7.3
19 2 6.7 9.3
10 3 4.5 9.3 4.5
[Code]...
As you noticed in the input the first number is the student ID, the second number is the number of tests made by the student, and the other 3 numbers are grades, in the output the first number is the student ID, the second number is the average of the tests, and the other 3 numbers are grades, I don't have a problem opening and saving a text file and neither creating a tab with 2 RTB , my problem is how do I tokenize or read the input line by line, i guess that i need to use the split function but I don't know how to implement it into the program.

I have a program that needs to display a playlist of songs, for a band performing someplace, from a .txt file. The songs in the file are listed as follows:
All You Need is Love-Beatles
Rock
4.25
[code]....
The first line is the song's title and group name. The second is the songs genre. The third line is the songs length, 4.25 is 4 minutes and 25 seconds.upon clicking a button, I need to display a playlist from this .txt file based on the number of minutes the band has to play, minutes entered into a TextBox, and the songs genre, selected from a ComboBox. The songs cannot repeat and must be random.I have already coded the program to read the .txt file but have not clue where to start with the rest.

Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties

I'm trying to create a program which reads a text file into an array.
[Code]...
But that's just silly so how can I fix this? Lines isn't being assigned a null value it's being assigned the first line of text in the file which has text in it so I'm confused.

My application reads information from an Excel spreadsheet into a DataSet (ds1) which is then filtered into another DataSet (ds2) based on user-specified criteria. The information is basically telephone call logs that reflects when a phone call was made,what extension it was made one, how long the call was, what number was called, etc.When the user's "search" criteria is matched in ds1 above, the application adds the number called to a ListBox on the form. When the ListBox Item is selected, additional information (call duration and such) is displayed to the right of the ListBox. My problem is that a single phone number could have been called multiple times on an extension within the date range the user specifies and for each occurrence of that number in the ListBox, the "expanded" info only reflects the information for the 1st call to that number listed in the DataSet.
The only unique identifier I have is the DateTime field for the row (as this goes up to the second). I thought about putting it into the ListBox item, but I'd prefer that this date not be visible until the user selects the ListBox item to view the details for that call. [code]

I am developing an application that reads an MDI applications child window and grabs the information from a control such as a textbox or listbox. I have tried to use Findwindow in order to accomplish this. I have gotten all the way to the control, but once I get there it returns blank. Can anyone point me in the right direction to accomplish this.I am able to read the window title and get the control title but when I send a message to the window it returns 0. Now I am just experimenting so I have no concrete code, but here is a snippet. [code]

I have a win form with three textboxes that lets the user input information using VB.net 2008. I am wanting the program to send me the information entered (when they hit the send button) as an email and also drop the information entered into an access database.I have the program sending the textbox information as an email.What I am having trouble with is saving the three textboxes to access database. I have an access database set up with a table and three fields for the three textboxes.
All I need to do is each time a user uses the program, it adds the information they enter into the three textboxes to the three different fields in the database. I don't need to let the user view or edit the database in any way.

I'm looking for a solution for making the program response to the enter/return key inside a textbox. After browsing the forum I end up with this
Private Sub TextBox1_KeyPress(ByVal Keyasii As Integer)
If Keyasii = 13 Then
Label1.Text = TextBox1.Text
End If
End Sub
As this seems to be the answer to the problem, I still can't make it work. I just get a 'beep' and nothing happens.

I have a hardware which sends out packets containing 17 bytes to the comport in bursts of 3. the little test VB that I have written receives and displays the bytes in a line of 17 bytes long and works fine until it gets to around 170th packet, then it starts to mix up (looks like shifting the data left) the bytes shift mostly by one digit sometimes by two. then it will continue to give almost a packet correct and a packet shifted for about 50 packets. Then it will correct itself for a long while, but then the speed at which it receives drops. All the packets are sent 3 times, and before things go wrong (within the first 170 packets) the packet counter shows that it receives 3 packet each time but after the problem it goes to 2 packet per burst and then to one.
If i close my VB monitoring program say at packet 165 and immediately open it again, it wont go wrong for another 170 packets, this points the finger at VB. I have check my hardware, there is no problem with that.The program reads port - waits for 17 bytes - once 17 has been received it will go and buffer the packet in an array. In fact they are 2 arrays but printing fro either results in the same problem.I have tried whatever i could think of but to no avail, i am wondering if some kind of house keeping needs to be done to clear something... I am sorry the program is a bit messy but I have been making many changes to find out what the problem is - my code below:[code]

I'm making a program that displays information for a dungeons and dragons game. i have a main form that displays all the information from a .txt file. I've made a new form that creates a new character. on this forum there are currently 7 text boxes and 6 combo boxes all containing different information for the new character.
The problem is now i want to save the new text file with each line of the text boxes and combo boxes on separate lines in the text file. My current plan was to put all the text from the 7 text boxes and combo boxes into one "main" text box then save that text box.

How do I make the data in the TextBox1 into a string, which will then become the data added to the text file after the button is clicked
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
IO.File.AppendAllText("C:UsersPublic est.txt", TextBox1)
End Sub
And yes, I realize that I have no idea how to use the insert code feature.

I am making trying to make a program that can read the file information directly from a specified file, but I am having a lot of difficulty reading things like file comments.An example of this can be found in windows XP when you alternate / right click on any file and click on properties. You'll get a lot of extra information.Now I have a few questions about this.
1.Can this information even be read in VB.NET
2.If so how
3.If not do I need to create some kind of data file to store the file information
Here is what I did so far

am explaining this stupidly, but I'm still very much a VB newbie. This is a question about uni work, but it's not an assignment/test, just a little optional extension task.I have three text boxes, the first one is where the person's name is entered and the next two are where you enter the (same) person's score for two tests they have completed.

I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?
Private Sub txtDestPayRate1_KeyDown1(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtDestPayRate1.KeyDown
If e.KeyCode = Keys.Enter Then

I'm trying to make a Lottery program on visual basic 2008, but there's one thing that I am stuck with.Note: My explanation may be hard to understand, so if you would rather have me send you my code and see how it works, I'm fine with that. My code is pretty long so far, so I didn't know if i should post it on here.
My program has 6 picture boxes lined up horizontally, and has one text box underneath each one. There is a play and stop button on the bottom left corner.I've altered my program to have animations for the picture boxes. Instead of having a random picture picked, I have it so that each picture box scrolls through a series of 10 numbers when the user presses play.
When the player presses stop, the picture boxes stops scrolling, and random pictures are displayed in each box. (The picture is really just a black circle with a number in it).The text boxes below the picture boxes are for the user to put numbers in. These are the numbers they select for the lottery. Now this is my predicament. Since the picture boxes decides what the winning lotto numbers are, how can I compare the numbers in the text box to the pictures?

The duplicates need to stay as they are in the text file. I just want the duplicates deleted from the listbox when viewed. How would I do that? Say there are two orders made by the same user. I only want the user to show up once in the listbox...

Write a program that makes change for amounts less than one dollar. Input to the program should be an integer less than 100. Output should be the original amount together with the proper set of coins that add up to that number. The program should produce change consisting of the minimum amount of coins possible. The output should be printed in such a way as to avoid unnecessary amounts.For example:
32 cents should be printed as:32 requires 1 quarter, 1 nickel, and 2 cents Rather than� 32 requires 1 quarter(s), 0 dime(s), 1 nickel(s), and 2 cent(s)

The projects I've made in VS 2008 and VB6 are pretty basic. I use VS 2008 now, and I was wondering how I could accomplish something like this:Let's say I want to make a toolbar and in the toolbar (under Options...) I want to open up a dialog box that will allow users to change preferences to the software I've made. Let's say, for instance, they can set the background color of the main form to customize their software a bit.
