Form And Webbrowser Creation
Jul 25, 2009
ok so heres what im trying to do. I have one form with a textbox and a button. im trying to make it so that when you type in the word "internet" a new form will be created and it will have the following components inserted onto it;
one webbrowser
one textbox
eight buttons
im not really having a problem making a new form so much as having a problem putting the tools on it, heres what i have
Dim screensaver As New Form
Dim back As New Button
Dim forward As New Button
[Code].....
vb doesnt say i have an error or anything like that, but i cant create "internet". i can create the form but cant put any of the components on it.

I need some input refactoring an asp.net (c#) application that is basically a framework for creating dynamic forms (any forms). From a high level point of view, there is a table that has the forms, and then there is a table that has all the form fields, where it is one to many between the two. There is a validation table, where each field can have multiple types of validation, and it is a one to many from the form fields table to the validation table.
So the issue is that this application has been sold as the be-all-end-all customizable solution to all the clients. So, the idea is whatever form they want, we can build it jsut using DB configurations. The thing is, that is not always possible, because there is complex relationship between the fields, and complex relationship between the forms themselves. Also, there is only once codebase, and this is for multiple clients - all of whom host it on their own. There is very specific logic for each of the clients, and they are ALL in the same codebase, with no real separation. Sometimes it was too difficult to make it generic, so there are instances where it has hard coded logic (as in if formID = XXX then do _). You can also have nested forms, as in, one set of fields on its own within each form.
So usually, when one client requests a change, we make the change and deploy it to that client - but then another client requests a different change, and we make the change and deploy it for THAT client, but the change from the earlier client breaks it, and its a headache trying to debug, because EVERYTHING is dynamic. There is no way we can rollback the earlier change, because then the other client would be screwed.
Its not done in a real 3-tier architecture - its a web site with references to a DB class, and a class library. There is business logic in the web site itself, in the class library, and the database stored procs (Validation is done in the stored procs).
I think this is a bad model in general, because one of the things I heard one of the developers say is that anytime any client makes a change, we should deploy to everybody - but that is not realistic, if we have say 20 clients - there will need to be regression testing on EVERYTHING, since we don't know the impact...There are about 100 forms in total, and their is some similarity in them (not much). But I think the idea that a dynamic engine can solve ALL form requests was not realistic as well. Clients come up with the most weird requests. For example, they have this engine doing a regular data entry form AND a search form.
There is a lot of preserving state between pages, and it is all done using session variables, which is ok, except that it is not really tracked, and so sessions from the same user keep getting overwritten, and I think sessions should be got rid of.Should I really just rewrite the whole thing? This app is about 3 years old, and there has been lots of testing and things done, and serious business logic implemented, so I hate to get rid of all that (joel's advice). But its really a mess of a sphagetti code, and everything takes forever to do, and things break all the time because of minor changes.
I've been reading Martin Fowlers "Refactoring" and Michael Feathers "working effectively with legacy code" - and they are good, but I feel they were written for an application that was 'slightly' better architected, where it is still a 3-tiered architecture, and there is 'some' resemblance of logic..

I'm trying to build a form which generates itself as it is used. I have created a really simplistic example, loosely related to what I'm trying to do below, but which demonstrates the problem.The user types a word in the text box, clicks the Button and a new TextBox is loaded into a Panel, with the value in the original TextBox that the user has entered. The user should then be able to type something else/the same and create another text box with that in it by clicking the button, basically permitting 0,1,..,n textboxes appearing above the "txtFeeder" TextBox on the form.The problem is that everytime you click the button, it doesn't add a new control, it seems to just update the one that has already been created with the new (incremental) ID. I'm not sure if I'm doing something wrong, or if what I'm trying to do can't be done (which I find hard to believe)?Here's the .aspx...
<form id="frmMain" runat="server">
<asp:Panel ID="pnlAdded" runat="server"></asp:Panel>
<asp:TextBox ID="txtFeeder" runat="server"></asp:TextBox>[code].....

I have an assignment I need to make and I have to make an app where the user can create a map/floorplan.So basically they open up the program go to create or edit and they should get a blank or already made floor plan.After that they should be able to add new icons/components to the floorplan or change them location wise on the floor plan.I have been searching into custom user controls and a few post I found on the internet about dynamically creating buttons.The dynamically creating buttons could do if the users can modify their locations and if it could save the whole form after being altered.However I want to be pointed in the right directions and know if any of these will work before I start doing more research and going more in depth.

Does anyone know if it is possible to open a firefox webbrowser in a form.Or does it take you default web browser as the webbrowser to open in form.
Eg - My Default Browser is Firefox - so does that mean the webbrowser control would be a firefox based one.

I am writing a little application for our end users. I am trying to perform a search, which takes 1 input and clicking a button.I have tried a couple attempts but have failed. I'm not sure where to start, because debugging it doesn't help me see what's going on.
source code:
<form action="" onsubmit="return false;">
<p>Enter SKU or Mfg Part #: <input name="ProductID" id="ProductID" type="text" size="30" /> <input type="button" name="btnSubmit "value="Go" onclick="loadProductID();" /></p>
</form>
attempts:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Dim theElementCollection As HtmlElementCollection = Me.WebBrowser1.document.GetElementsByTagName("input")
'For Each curElement As HtmlElement In theElementCollection

I have a Form that has some Labels and Buttons on the left side and a WebBrowser on the right. I would like to let the WebBrowser fill the rest of the Form when it is resized. Resizing of the Form works, but the WebBrowser always has a distance of approximatel 150-200 pixels from the border of the Form. I'd prefer it to fill the form up straight to the borders of it. Can anyone give me a hint on how to change that behavior?
Another thing I couldn't figure yet is how to get the form to show a Scrollbar when it gets so small that the labels and buttons on the left get out of the form.

I'm using Visual Studio 2005, net framework 2.0, Microsoft Internet Explorer ver 7.0.5730.13. Create a form with the webbrowser control and two buttons. Use the code that i provided at the end of this question to understand the scenario. As far as i know, this behaviour happens only on the myspace.com web site. 1. Navigate to your myspace.com inbox page, read a message and click on the reply button to reply to the message. The page will show correctly in the web browser.2. Then click on Button1, repeat the same process (read a message in the myspace.com inbox, click on the reply button), and the textboxes where you have to enter your reply will be gone.3. Then click on Button2, repeat the same process, and the page will show correctly in the web browser.4. Then comment out or remove the oDoc_MouseDown event, click on Button1, repeat the same process, and the page will show correctly.Why does the page shows correctly when the oDoc_MouseDown event is removed? The same behaviour happens if you use any other event of the oDoc variable.I desperately need the page on myspace to be shown correctly with the oDoc_MouseDown event and other events of the oDoc variable. Please provide a solution to this
problem.RegardsPublic Class Form1 Private WithEvents oDoc As HtmlDocument Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load wb.Navigate(" ") End Sub Private Sub Button1_Click(

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..

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!
