Finding The Webpage Manipulation Code?
Jan 21, 2012
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 need to be able to find a piece of the webpage source. It always starts the same, but as a random number behind it.
So sometimes it could be...
Example.com/123345
And Sometimes...
Example.com/098765
But will always start the same. I only need part of the source, not all.

I can now navigate to pages, fill forms, submit forms, click elements etc.My next big step will be collecting html element ID's which are constantly different each time I navigate to a page.On the webpage I am working on, each page contains 10 of these ID's.
ill_btn_20234518
ill_btn_20534538
ill_btn_20174048
Now I am just looking to click on one of them at random for right now. It doesn't matter which one. Or perhaps the first one to appear on the webpage.Here is the code that I tried first........it works fine for clicking static buttons (without the random id #'s at the end)
Dim ill As HtmlElement = WebBrowser1.Document.GetElementById("ill_btn_")
ill.InvokeMember("click")
End Sub
I guess what I am looking for here is some sort of partial id tag, to let it know to search for the first ID that begins with ill_btn_ ?

I need help to form a code for a small arrays manipulation. The input data are known: they are two integers "N" and "s". An integer "N" is always divisible by 4.I need to create an array of "N" members, by repeating (N/4 times) this sub-array: 1,2,2,1 (always is the same). In the picture, this is shown in blue. Then I need to add the same array to the existing array, but shifted for "s" places (red array). The result is "yes" if each sum in new columns is always the same (3). Otherwise the result is "no." note there is no need to draw or display something (DGV, table ...). The required result is only "yes" or "no".

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 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?

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.

I need to make a super simple web-page monitoring tool in VB.Net that checks FieldNation.com every few minutes for new work orders. To do that, I need to log in to their page. I think I can figure out how to read the page once I'm logged in, but how can I actually log in? I heard it had something to do with WebClient.

I am developing an intranet site using VB.net 2005. I have a list of reports and their URL's located in a table. The list is displayed to the user using a Gridview control with select turned on. when the user selects one , the selected index changed event triggers looking up the URL from the table and stores it in a session variable. the problem i have is that i now need to open a new web browser window and display the page.
I tried using the envDTE.ItemOperations.Navigate but all of the information provided for this process is written in VB6 and VB2003. In 2005 the DTE proces is not native and when you assigned the ENVDTE.Itemoperatiosn to a shared variable (or any type) and
then try to navigate you get the following error: Object reference not set to an instance of an object.
so i tried to create an instance but when i try:
ItemOp = DTE.ItemOperations or
ItemOp = EnvDTE.ItemOperations
it gives me an error indicating that this is not possible. My quesion is, does anyone have the correct syntax for using the envDTE.ItemOperations.Navigate instruction from Visual Basic.Net 2005? None of the microsoft pages or microsoft books provide correct syntax. Or does anyone have any substitute code that can navigate a user from a protected sub in one page to a new web page?

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

Would it be possible to basically make a full web page appear in a windows form application as an image? Sort of like a print screen command, but just for the web page itself. I need this to show any web page in overview as a image in my program, but I have no idea how to go about this. I suppose it would be almost like a web browser; other then that you can't click links or interact with the page at all, as it is an image. Preferably without loading the web page then converting it, but having it as in image as you load any given page - not sure if it's possible with just VB. Even a rudimentary method would be much appreciated.Note: I'm not to great with VB, so if you don't mind, please provide as much detail as you can with any given code,
