Forms :: Handling More Than One WebBrowser Tool In Same Form?
Apr 6, 2011
I am trying to pull some report details from a website. my home page is having a list of Report IDs, by clicking them i will be navigated to the detailed reports.. Similarly i have so many report IDs in my home page... i have loaded my page in webBrowser1 and capture the link of the first report id by looping through the page. After capturing the link of first report id i am trying to navigate to the link using webBrwoser2 which is placed in the same form. the page loaded sucessfully and i can extract the report to the textbox.
Here is the problem : before complete the navigation action in webbrowser2 the first loop used to get the links of report IDs got completed. So i am not able to loop all the report ID's Link to get all details.
I am not sure i am doing the right way of extracting a data from a web page..

I'm writing a tabbed web browser for someone who is learning VB.NET, and I have got to the point where I can add/remove browser controls into tab pages, controlled by one set of buttons on the main form, but I can't handle events from the WebBrowser objects.I have tried this but it says that 'DocumentTitleChanged' isnt an event of 'Control'...
Dim browser As New ArrayList
browser.Add(New WebBrowser)
browser(0).parent = TabControl1.SelectedTab
browser(0).dock = DockStyle.Fill
AddHandler browser(0).DocumentTitleChanged, TitleChangedHandler()
I want to update the tab title with the web page title when it changes. I started using a timer to update the tabs but there must be a way to add an event handler here.

I have an application that loads a website into a webbrowser control that is on another form (Form2). Unfortunately, during debugging, the contents of the webbrowser does not show. The remainder of my program depends on the information obtained from the loaded website but since it does not show

Just moved a .NET 2.0 App from VS2005 to VS2010 and noticed that now when a window containing a WebBrowser tries to retrieve a pdf it thows out an error (unknown file type System.Byte[]). This would usually indicate that Acrobat Reader has not been installed - but open up IE9 and enter the link into the address bar and the PDF displays in the browser without any incident!
Should point out that the app created in VS2005 and installed on Win 7 (actually Server 2008 R2 in 'Workstation Mode') has the same issue.. All works fine in XP and below... Do seem to remember this on a Vista box, but put that down to Acrobat not being installed!

After I send a post request to a site/forum and successfully logged in,
1) How do I save/read the cookies so that when I visit other sections of the site/forum I remained logged in?
Eg. I want to login to a forum and read a thread that only forum members can read.
Also, when I log in in the web browser tool (GUI) of vb.net, the cookies seems to be saved by the browser. Those cookies are also shared by Internet Explorer browser.
2) Is there a way to get the cookies from the web browser tool or Internet Explorer so I don't have to login and read/save the cookies programmatically?

I am attempting to write a VB.net application which will allow users to create their own widget plugins in html/jscript and i would like to set my own security options in the applications settings allowing users to choose what can run or not eg scripts, flash, activex.I would like to allow activex controls to be used without the windows security dialog in the WebBrowser Control (An ActiveX control is trying to interact with the page...) or what ever it says.
I started customizing the WB Control to suite my needs implementing various interfaces such as IOleClientSite, IDocHostShowUI, IDocHostUIHandler, etc...I can't seem to find anything that will allow me to control the security permissions of the WB Control. I tried to implement IHttpSecurity and IInternetSecurityManager but I'm either barking up the wrong tree or not doing it right.

I'm writing a simple application - address book. User enters new addresses and they are added as an entry to a list visible on the main form (frmStart). I use one form to add and edit (AddContForm). Add button on the frmStart works fine, however I experience some problems with the edit button as when I press it and enter new data they are added as new entry however the previous entry is still there. Logic is handled by Contact.vb class.
Contact.vb
Public Class Contact
Public Contact As String
Public Title As String
[code]....
Update:I really don't care much for whether the data on the AddForm is the old data or the new data. I think the problem now is that when I click edit previous entry on the list is not deleted (what I believe I have indicated in my question) - I tried to delete it (by using the if condition and checking what button was pressed) however it seems it is not working properly for some reason.

I need to be able to add buttons to a tool strip at run time. As of now I've been able to get the buttons to display with a nice little picture just how he wants and some text under it. Just can't figure out how to "enable" the click event for these buttons. Obviously I need them to do something rather than just sit there looking good and this is where I'm stuck. Right now I'd be happy for a message box to come up saying yep I'm working as I could then work with that. This is what I have for code so far... this is just to get it working I'll work on the actual code later.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim btnSomething As New ToolStripButton
btnSomething.Text = "Test 1"
[code]....

I'm trying to figure out how to make dragable controls like the ones in paint.net. see the attachment. they look like forms kind of because they have the red x at the top like a form does, but it kind of looks like a custom control too. Is it possible to make these types of controls in VB.Net 2008.

The Parent has a Tool Strip and on the tool strip is a button that when clicked loads the child, this works fine.But when I set the child form to maximize its title-bar jumps over the Parent tool strip. Pushing it down a bit. I do what this. I would like the child to be completely contained within the Parent including the Parent forms tool strip.

I am trying to create a form where depending on what the user selects, they are shown a collection of images from the web. Depending on what they select there will be a different amount of images so each picture will need to be added dynamically.
I am able to create PictureBoxes dynamically however I'm stumped how to create event handling in order for each control to give a unique response.This is what I originally tried but I got an error..
Private Sub Form1_Load
For i=0 To 10
Dim picBox As PictureBox
[code]....
The error I got was
'AddressOf' operand must be the name of a method (without parentheses)
How ridiculous that you can't include arguments in your AddressOf! Can anyone shed some light on my situation (or knows a better way of carrying out my goal)?

I have tried most thing like setting the form border style to none on the child form but still I get two tool bars. I would like to remove the tool bar in the black square

In old VB6, I could set all txtBox controls when members of the same index eg.txtBox(0),txtBox(1) etc., to all do certain things in a couple of lines of code, eg.
Private Sub txtBox_GotFocus(Index As Integer)
txtBox(Index).SelStart = 0
txtBox(Index).SelLength = Len(txtBox(Index))

I have a form called BaseReportForm that handles drawing some stuff to in a panel to create a template for a bunch of reports. The drawing all takes place in the Panel's Paint event and this form will always be inherited. In the inherited forms, I draw the specific details of the report in the inherited form's Panel Paint event. So I am drawing to the same panel from the base form and from the inherited form. It all works fine, but when I try to open the design view for the inherited forms, I get the following error..
Quote:
The event Paint is read-only and cannot be changed.
I'm not sure I am handling my paint events correctly. Is there a different way I should be handling the drawing of these reports?

I am just for learning purposes trying to develop a one player text based game.
I have a rich text box (GameWindow)
I have a text box (InputWindow)
I have a button (InputButton)
and a bunch of labels that aren't really important
I have two questions first is easy probably. How do i get InputWindow to respond to me hitting enter when text is in it?
[Code]...
But if i plan to have more that is only going to increase the size and code needed and im sure there is an easier way i just don't know how to do it.

I have a delete button in a datagridview. The button works fine however when there is nothing to delete it throws an index out of range exception. Now I know for a fact people are going to click that button even though there is nothing the I am presuming the best course of action is going to be a try/catch but I am not sure how to do it. My code is as follows,
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
If e.ColumnIndex <> 7 Then

I hope I got all that in this question title. Let me explain. We are starting on small desktop app that will snowball into a big app with many forms. The database is SQL Server. It will have classic stored procs/functions performing classic CRUD functions. Given a table or stored proc in SQL Server what is the quickest way to create a form with all the hooks to maintain a table.
For e.g. lets assume I have table like this (most code below is pseudo code)
Table Employee
{
Name varchar(30)
DOB Datetime
Address varchar(100)
}
From this as source I want to create my Target which is form with 3 labels and 3 textboxes with add delete modify buttons (or OK button to add if not exists or modify if exists)
[Code]..
The code generation tool or technique that will be used should generate the correct db hooks (create SQL parameters, SqlCommand, execute sql.. basic try catch etc. Is there any open source tool to do this ? Some trick or templated approach via VS 2010 ? Worst case any third party tool ?

I am developing a windows based application in VB 2005, the main form of the application is of fixed border style (i.e. user cannot resize the form), but in certain cases I am resizing my form through code. Intially the form has a fixed height i.e. 350 for normal height and 400 for extended height. But in this case the problem could not be solved effectively as the user can have different DPI setting e.g. 120, 144, 192 etc.The logic I implemented is to divide my form (vertically) into 3 parts
