I know that you can create routes in asp.net web forms, but how do I go about creating one that handles all my pages like [URL]? I do have a file called page.aspx that will process all the requests for the CMS. I think it's a root handler I need.
View 2 RepliesI have inherited a really awful webforms application that is all kinds of bad--an untestable hairy mess of datasets and Page_Load events. Object oriented? N-tier? Unit tests? source control? All academic niceties to the team that built this mess.
It started life as an asp classic app, got mostly ported to VB.NET. Management denied my request to "nuke the entire site from orbit" and start over.

I know we might be able to interoperate between the legacy webforms and mvc. The question is, can we leave the legacy code in VB and build the new stuff in C#? I want to force the conversion to C# so the team doesn't fall back into bad habits.
Is there an MVC 2 Areas strategy that we could use here?

i'm planning on creating an application that uses both winforms and webforms and i have a few concerns before i proceed.1. is it possible to pass data between winforms and webforms?2. how about passing objects like connections, datatables, dataadapters etc. between webforms and winforms?3. i want a centralized authentication for all forms and webpages... meaning if i'm authenticated in a winform, i should also be authenticated when i launch a webform thru the winform and vice versa.
View 9 RepliesI am trying to write an onclick event for textbox but VB.net does not seem to support textbox1.click(). I want to open a new form every time someone clicks on the textbox. Opening a new form is no problem, but I cant detect the click. Is there any event for textbox that detects click event? I saw something like TextboxBase that has Click but I am able to use it well.
This is how my class looks :
Partial Public Class TextBoxClick
Inherits System.Web.UI.Page
End Class
It has some basic load and init events. I am trying to write a Sub like this :
Private Sub incident_clicked(ByVal sender As Object, ByVal e As System.EventArgs) Handles Incident.OnClick
Incident.Click does not work either.
I am guessing I need to import some class to access the Click event but I am not sure which.

I have been searching all morning for a sample showing a simple "find" example for an ASP.NET Webform, where a "find" button is used to find a string in a Textbox, and then Highlight it, like Word does. The following VB6 code worked perfectly, but I couldn't find .Selstart or .SelLength properties in the Text property of the ASP.NET textbox.
'find the first instance
Private Sub Command14_Click()
Command36.Visible = True
[Code]...
Is there a way to Select the Length and Start of the string in ASP.NET. The Winforms code is very similar to the VB6 code, so maybe I'm just missing something simple.

My problem in the Combo Box and SQL query .. I have three comboboxes linked to an Access 2007 database
[Code]...
I'm not 100% sure where to post this, as I'm making the program in VB.net, however It is linked to access and is getting the information / saving it into there.
I have a customers page and a jobsheet page,
the customers page is where the information on the customer is stored e.g. "Company" ,"First name" and "Last name".
When I Go into jobsheet, I have made it in so that company searches for the record from access so there is a list e.g. "Big W" , "Bunnings" etc, and tied up to the company is a name of the person in that company.
My question (after all the babble) is how can I make it so when I choose "Big W" from the list, it auto fills in the "First name" with 'John' and last name with 'Smith' , and if I choose Bunnings it uses the name associated with that and etc for the other companies.

Ok basically I want to select a point on a bitmap and then fill all of the color that is the same as the color at that point touching that color with a different color. If that sounds confusing, just think of the paint bucket tool in mspaint or photoshop. Currently I do this by starting with the point selected and then check all the points around it in an ever expanding box until at last no new contiguous points of the color to replace are found.The bad news: This is slow as heck =(I remember my windows 98 computer could handle this just fine with no noticeable delay. So I'm either missing something algorithmically (is there a better approach) or VB.net is just too slow to accomplish this without some sort of different approach/optimization.
[Code]...
As you can see, right now I just select the middle point as where I want to start filling from, and I fill with the color aquamarine. later I want to make this more flexible, but right now I just need this to be faster.
My general algorithm works like this:Start with a 3x3 pixel box with the first pixel (already changed to your new color, with the old color stored) as your start point.Check if each pixel is the color you stored (the one you're replacing) If it is, check if it's next to the new color you're replacing the old color with. If it is, replace it and increase the size of the box.The process ends when no new pixels are replaced.
i have a combo box that i'm trying to fill from a database, managed to get it working through the wizard and the form view method but could do the next bit that way. I then started to try it the coded way, got the database linked but it only shows the first name in the database, how do i get it to show all the names in the database?
this is the code for the form

I'm trying to get a combo box to fill itself from a MS access database field but I can't get it to work. I can get it to work at school but not at home. Also can't get a program that worked at school to work here so I'm guessing that somewhere there is something blocking the connection to the database. I've gone into the MS access trust center and looked at the settings there but I can't see anything that would be stopping it. I just need to find that setting (if it is indeed a setting) wherever it is and fix it so that I can access my database. I am not using visual basic from access I am accessing access through visual basic.
I can't get it to work with an ADO connection, either. Also when preview data via clicking smart arrow on the combo box then going to preview data I can see the data just fine. Also I just noticed I get two lines in my output after the file is run that say "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll" I don't get these lines if I comment out all the code for the combo box.
I am trying to fill a combo box using a dataset and data adapt. I am struggling too work out how to do it. I thought it would have been easy but I was wrong. i can set the text to read the first line of the colomn but nothing else. I was wondering if anyone could help me out with what I have to do. I think I have to increment inc and add a line underneath but I don't know how to do that
comboMaps.Text = datSet.Tables("TheLastShot").Rows(inc).Item("Maps")

I have a combo box in a form, I want to fill it with names I have stored in a database.I know I have to use the fill command, but I am not sure what code I need to use.I imagine I need to place this code in the form load event, where I wrote my code to connect to the database.Tell me if I am wrong, but, do I need to create a sql fill command, select Names From Users, then execute that command in the combo box object.
