Modify Web Page Before Display?
Sep 1, 2010
I want to launch an instance of InternetExplorer from my application. I also need to modify contents of specific web pages before the pages are displayed based on user settings (e.g., bold certain phrases within the page and/or include user-specific data on the page).
Public WithEvents IE As SHDocVw.InternetExplorer
Public Sub ShowIE()
Me.IE = DirectCast(Microsoft.VisualBasic.CreateObject("InternetExplorer.Application"), SHDocVw.InternetExplorer)
Me.IE.Visible = True
End Sub

I am writing a VB 2008 program to display and update records from a sql database. This particular form is used to display and modify retail store information records from the database. I am running into an issue with saving the records once they have been changed.The error message I am getting is "Update requires a valid update command when passed DataRow collection with modified rows". I am including all of my code for the form because I am not sure what is relevant. I am getting the error when SaveTheEdit() is called on line 83. [code]

I am working on a text-based game and as your character moves, you get informations such as the room name and below, a description (Lorem ipsum in the example) which is an array of string. I would like to know how to append characters to it. I am actually trying to display a minimap made of ASCII character. See the second bloc code for an example.
From:
code:
Into:
Room Name Here
code;
The game itself is made in VB.NET but a solution in pseudo-code is also welcomed. Also, each line's length is aproximatively the maximum length it must be.
The desired output must be an array of strings because this data is later send to a client connected using sockets.

I make a panel visible that has a tab control on it.
The panel becomes visible - I can see all three tab pages.
But the contents of the tab page is blank - until I actually click a tab heading.

I have a tab control with 4 tabs. At form load time I determine which tab I need to have the focus (which one to select). I have tried using TabControl.TabIndex = 2 to set the desired index and TabControl.SelectedTab = TabControl.TabPages(2) as well as TabControl.SelectTab(SoftwareUpdateTabPage), however, none of these seem to work at load time. The tab enter of the first tab always seems to be called. Is there a way for me to select the tab I want in my form load function?
The second part is how do I disable (so the user cannot change to another tab) the other tabs at form load time?

I am just making the switch from WebForms to MVC and would like to ask what are the best ways of hiding particular fields in the view. Assuming we have a model named WishList that has a list of gifts kids want for Christmas and the child's name. We want the elves to view the list of gifts, but only Santa Claus can view the child's name. Would it be best to have two views for the WishList (one for Santa and one for the elves) or is there another way to handle this? My concern is that the number of views can start piling as high as the snow does in the North Pole by the time I enforce all of the visibility settings required in my application.

I have created a windows form application which goes through Internet Explorer index.dat files and extracts various information (URL's , date they were last accessed etc). I then display this information in a data grid view. From here i would like to be able to click on a URL link and open the web page without activating any active content (such as java script, activex, viruses etc). I have tried to do this using Internet explorer in 'offline mode' with the problem being if the web page requires an online connection it automatically changes Internet Explorer from 'work offline' to online mode. Is there a way around this problem? Or does anyone have any suggestions on a better way to view the web pages with no active content?

A few years ago, I remember seeing an MS Access application where the programmer displayed the first page of a Word document as a thumbnail on a form. I'm guessing that its highly possible that this is well within the limits of .NET - could anybody point me in the right direction to read-up on how I might do this?

Using a session variable in my VB.net site has been figured out just fine. I just need to get my welcome message to stay put on every page. I put the code and text box in my master page to allow the message to stay there, but my label with the user's name disappears when I click on a different page.
The session is still there because I have it set up to display the textbox to enter your code if the session is destroyed or not available for some reason.
my code is not allowing the First_Name and Last_Name of the user's session to show up? The problem is in the Page_Load but I thought I would throw in the whole master.vb file to show everything I have so far.
Partial Class MasterPage
Inherits System.Web.UI.MasterPage
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I have a page that allows users to "upload" a file. The page includes an asp.net fileUpload control. However, all it does is send the byte array to a WSE 2.0 web service. I can't change this. This may be updated in the future, but for now, this is what I have to go with.The page has an animated gif that starts when the user clicks the submit button. And the page should be updated accordingly based on the result returned by the web service call. I'm able to start the gif and consume the WS successfully. However, while the page is hitting the web service, the gif file freezes.
I then tried to use a separate thread to consume the web service. This speeds up the process and does not freeze the gif, but the page is not updated when the web service completes. If I put the main thread to sleep, the page updates, but I'm back to the same issue mentioned above, where the gif freezes. I'm pretty sure I could make the call using javascript and update the page that way, but at this point, I'd really rather do it server side (out of stubbornness if nothing else).

I have a working code that exports the datagrid into XLS. However, the datagrid results does not show on my aspx (html) page. It only shows on the page when I comment out the part that exports it to xls. I am not sure whether it should show by default when exporting.Basically, what I want to have is when I click my export button, it should display the datagrid on the page as well as popup an excel "open, save, cancel" window for the export.
Here is my function for referece:
Public Sub Convert(ByVal ds As DataSet, ByVal Response As HttpResponse)
Dim attachment As String = "attachment; filename= ExportPRFs_" & Today() & ".xls"

I am using VB 2008.I've successfully "scraped" web sites before but I am having a problem now.I use a web browser component.I retrieve the test from the control and then I search the text for the information I am looking for.BUT, when I try to do this a website that displays its information in FRAMES, it does not work.The web browser correctly displays the page, but the text only includes text saying that I need to use a browser that can handle frames.I do not understand how the web browser control can correctly display the web page (including the info that I am looking for, but the text/source/document property of the web browser does not include all of the text on the page.

I have a class and I am trying to randomly select 3 items to display on a page (each item should be unique so that there is no repeating).I have some code that works(ish). The problem is that when I track the random numbers it takes about at least 50 attempts for the application to select a different random number than the one that was chosen the first time (defying the laws of probability).[code]
