I'm storing a multi-line text file (in .dir format) in the directory the user chooses, and what I need to do, is when they import it (which my program can already do) I need it to find the end of the file (line) and then read that line, that line will be a number which corresponds with a number system. Basically, the file looks like this

I am a newbie when it comes to programming. Right now I am trying to create a program that will read in a .txt file that consists of different integers on each line. For example, the .txt file looks something like this:
[Code]...
I loaded a text file to a text box, and I want the program to find a certain line containing only the strings I specify. But the text file will likely contain many of them, so I want it to pause scanning at the first line I'm looking for until I tell it to continue, then the second line, and so on. So the questions are:
1. What's the method for finding the exact line I want in a text file?
2. How do you start, pause, and resume scanning a text file line by line?
I need to find certain text in a text file or text box and copy next line. How can I do it?

View 8 RepliesI am working on a little small 10 question quiz. The quiz is just for fun for a work thing I'm doing. I'm using VB.net. I'd like to put in one of the questions something like "what's your favorite baseball team?" Then list 3 radio buttons for 3 possible answers. But I'd like to make 2 of the radio buttons move away when a person tries to mouse over it to click on it. So only the answer I want them to use would be possible. I can creat it all but the code to make the raido buttons move when moused over. I've been searching but having trouble finding anything on how to do this.
I don't have my actual quiz code in front of me. But can post the form code for that question later tonight when I get home if needed. But the form is very basic. just has the question in a lable, Then the 3 answers below it as radio buttons. I have a next button that goes to the next form and closes the previous one, and an exit button that closes down the whole application.

I am trying to write a VB function to strip unwanted characters from a string. It is for generating a 'clean' url from data that has been inputted into a CMS.

I have a vb.net / ado.net application for distributors that queries a sql server db, converts the records to tab delimited text format file. After building the file, the user goes to the website of the manufacturer, logs in to a private area and uploads the txt file.
I would like to add a function to my vb.net code that would launch a browser in a form, load the manufacturer's login screen, load the user id, password and then let the user log in by clicking the login button. Then when the next page loads, I'd like to have the text file I just created pop into the web page text box for file name, choose a couple of radio button options properly and then let the user click the submit button.
I must admit it's been a few years since my RegEx class and since then, I have done little with them. So I turn to the brain power of SO. . . I have an Excel spreadsheet (2007) with some data. I want to search one of the columns for a pattern (here's the RegEx part). When I find a match I want to copy a portion of the found match to another column in the same row.

View 1 RepliesI have the following code for finding factorials:
Private Shared Function Factorial(ByVal Number As Long) As Long
If Number = 0 Then
Return 1
Else
Return Number * Factorial(Number - 1)
End If
End Function
It usually results in an overflow. It only works if I start with something small like 4. I have to work with starting numbers such as 30-60. I thought changing the value type to LONG would prevent this problem. This is VB.net just for reference.
There may be times when it would be useful for your code to be able to find and close modal dialogs displayed by an application. Perhaps you do not want to have to wait indefinitely for your user's input, or are using the COM Web browser control to automatically navigate Web page and would like to interactively close alert messages that pop up.Digging into our Interop toolbox, we find that this is a relatively simple process using a few core Win32API calls. Starting with the handle of the main window associated with the dialog (this is the form from which the messagebox was shown, whether from your code or from a Web page hosted in a Web browser control on the form), the GetWindow function can be used to retrieve a handle to a dialog windows (called a popup by the Windows API) being displayed (if any). The same function can then be used to enumerate the child windows of the dialog to find a button on the dialog to click in order to close it, and the SendMessage API function can be used to simulate that click, effectlvely closing the dialog window.
NOTE: At the top of whatever code file you put this code, be sure to include the following line (thanks poiygon for pointing this out):Code:Imports System.Runtime.InteropServices this allows for the shortcuts to the DllImport attributes.[code]This sample can be easily modified to close a dialog in another application (by using the MainWindowHandle of that application in the LookForAndCloseIEPopup function, instead of "Me.Handle") or to close any other type of modal dialog message being displayed to your user.
I need to find .MP3 format URLS in a HTML source code.So how could i do that?Lets say i have:
Dim wcClient As New System.Net.WebClient
Dim data As System.IO.Stream = wcClient.OpenRead(inbox.ToString)
Dim reader As System.IO.StreamReader = New System.IO.StreamReader(data)
reader = reader.ReadToEnd()
reader.Close()
so how could i find all the .MP3 urls which are in the source code?
I've found some examples using RegEx but im not really sure how to use the RegEx pattern to find MP3 urls in the source code.

View 14 RepliesIs there any way I can find the exact reason a form is closing ? To be more specific , I'd like to find when a form is closing :1) because the user pressed the X button on the upper right corner2) due to code (Me.Close , MyForm.Close etc)I know I can use the FormClosing event and use this code :If e.CloseReason = CloseReason.UserClosing Thenhowever it seems that the CloseReason.UserClosing catches both cases (closed by te X button or by code) . So , is there any way I can find exactly the reason a form is closing ?Back in VB6 , the correspondent UnloadMode variable of the Form_Unload event could be "vbFormCode" which indicated specifically that the form was closed by code
View 4 RepliesI'm using vb.net. Basically, I have a drop down list, text box and a submit button. You choose a movie director from a drop down list, then type in a movie, click button and it adds the data to my database.There's another button which hides/shows drop down list, text box and submit button using Visible = True and Visible = False, but what I don't like about it is when it hides the things I said before, it leaves some white/empty space like if they are still there, but not visible.Is there anyway to put some kind of holder/container and place a button which when clicked could add my drop down list, text box and submit buttons to that place?
