Finding The Char Code Of A Character?
Jul 13, 2011
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. Someone has copied and pasted from a Word document and so there appears to be an mdash or ndash in the product title. This results in ─ appearing instead of -
I have tried a Replace(text, Chr(196), Chr(45)) but it isn't working so it can't be 196. Is there a tool or something where I can copy this character and paste it into the tool and it will tell me what char code it is?

What do I use to find the position of a certain character in a string? Lets say I had a number 12345.6789 I want to know how far the decimal point is from the left? Of course the position of the decimal will change as the number will change.

I am developing an application proj on it.. In that, I want to separate charaters of the string which is of following stream, 18 Feb 2011 06:05:24 0601 110218055515,3,26;9948;9948;9947;9951;9956;9954;99 61;9958;9965;9967;125672N0801272E;110218055550; In this I want to separate as, Mail recieved time = 18 Feb 2011 06:05:24 msg recieved time = 110218055515 msg sent time = 110218055550 Position = 125672N0801272E water level 1 = 9948 water level 2 = 9948 water level 3 = 9947 water level 4 = 9951 water level 5 = 9956 water level 6 = 9954 water level 7 = 9961 water level 8 = 9958 water level 9 = 9965 water level 10 = 9967 I am only aware of IndexOf and LastIndexOf methods, and these methods are used to find the index of first and last occurence character position, but I want to split the string in subsequent characters too..

I have a value I am pulling into a string that looks like this:
M'arta
I need to have it to translate the numeric value into an actual value so that the string looks like this:
M'arta
how to accomplish this in VB.NET? Here is the relevant line of code that returns this result:
Dim occupant as String = GridView1.Rows(e.RowIndex).Cells(2).Text

I 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 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.

I 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.

This might be a really easy one but I couldn't seem to find an answer anywhere I'm trying to comment my code as follows
Session("test") = "JAMIE" _
'TEST INFO
& "TEST" _
'ADDRESS INFO
& "ADDRESS = TEST"
With the code above i'm getting the error Syntax error But when I remove the comments like so
Session("test") = "JAMIE" _
& "TEST" _
& "ADDRESS = TEST"
It works fine so my guess is that I cannot comment my code between the _ character.

Is 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
