Asp.net - IE Not Catching Enter Key For Form Submission?
Jun 30, 2011
I have a simple form with one text box that pass data to SQL and I want it to submit when the user hits the enter key.
In Firefox, this works great. The user puts a number hits enter gets back the results.
However in IE 8 and IE 9 this is not working.
<form id="form1" runat="server" accept="cmdclick"
style="background-position: center; background-image: url('BG.gif'); background-repeat: no-repeat;">
[Code]....
I am not sure what would cause this. I see a lot of people using JavaScript to go around the problem however I do not know how to write JavaScript code.
How can this be done (preferably without JavaScript)?

I'd like to know if there are other ways to write a submission program (submitting urls or pad xml to directories, submission sites, blogs) other than using the webBrowser. I've evaluated some shareware programs that submit urls or data very quickly, like 100s in a matter of mins. I couldn't write a program using a webBrowser because it might take 15 secs just to load the url. How are they writing the code??

I am automating a javascript web form submission process using webbrowser. I would like to use something without a UI but don't think httpresponse etc would do all that is needed. My code works but I think is not designed correctly. I think I should be breaking each step into its own sub or function. In its current state I think every time a page is refreshed/redrawn all the code is running which makes causes endless looping of clicking a link which is on its own destination page. What that means is click the link and the page refreshes with new information but does not navigate to a new page. So the code looks for the link and selects it over and over and over .... This I think needs to be subbed or done as a function instead.
Here's the code.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Part 1: Load elogging login page in Form_Load event
WebBrowser1.Navigate("[URL]")

I have a little project but ive come to an error. What it does: It goes to a site, fills a form and then submits it. But the submit is too fast. I want it to fill in info, then wait 3 seconds and then submit it.
Here is the
WebBrowser1.Document.All("user[screen_name]").SetAttribute("value", TextBox4.Text & intcount)
For Each element As HtmlElement In WebBrowser1.Document.All
If element.GetAttribute("className") = "submit button promotional" Then
element.InvokeMember("click")
End If
Next
I want it to have a little pause of 3 seconds after the intcount).

I have created a page containing the Wizard control. It's a very simple one. User selects some data on the first page, clicks Next and then has a choice of Previous or Finish. When they click Finish the form is submitted but, for some reason, the font size of all my labels increases. There's nothing in the code of the Finish button that would do that.

is there a way that I can send what my client has submitted via a TextBox to one of my php servers? I googled it, and couldn't really find the answer I was looking for. Or if I did, it was a little too complicated for me. A link to a simple tutorial will do, if you don't feel like wasting your time taki

I've written a JavaScript function which validates form input and highlights the input fields and displays any error messages, which I have tested and all works fine. i have called this function from the OnClientClick attribute of an asp:Button tag. However, if the JavaScript function determines there to be validation errors, I want to stop the form from submitting. How do I do this?

Can you show the coding needed to disable the enter key on a textedit box or at the form level?This form is using multi-line textedit boxes and I would like to prevent the user from pressing the enter key from jumping to the next line in the textedit boxes.

Dim number = TextBox1.Text
If number < 1 Or number > 100 Then
MessageBox.Show("You must enter a value between 1 and 100", "Name Entry Error", _
MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
Exit Sub
End If
Whenever I enter anything other than a numeric value; the form crashes.

I have a form that consists of only a TableLayoutPanel (which fills the entire form) containing a vertical stack of buttons. The resulting app is used in conjunction with another app. What I would like is to have the vb app do something when the mouse enters the form. Unfortunately, all mouse enter/leave events are trapped by the panel or the buttons.
As a quick test I created a form with a tablelayoutpanel (docked to fill the form) containing one button. I added the following code:
Private Sub Form1_MouseEnter(sender As System.Object, e As System.EventArgs) Handles

I currently have a program that allows users to download files into a folder of there choice. I currently have 10 different forms all with a text box to show folder location and a browse button for user to find it, but what I want to do is create a form that will appear at the start where the end user can enter the folder location so that they don't have to enter the folder path for every download they want to do. How would I go about doing this I have a textbox, browse button and an OK button but have no idea what to do next.

When I debug a program my IDE simply does not catch System.NullReferenceException - execution continues as if there were nothing wrong.Moreover, when I go to the menu Debug/Exceptions System.NullReferenceException is not even in the list(Common Language Runtime Exceptions).
I manually add it (there is the Add button) and I put a checkmark in the 'Thrown' and 'User unhandled' column - now IDE catches it, but after I re-load the project the situation re-appears - and NullReferenceException is not on the list again. What may be wrong?
Update:No, when I step through the code the execution does not continue but exits the current block of code (sub or function). There were no Try...Catch blocks and there is a message: A System.NullReferenceException occured in MSCorlib.dll... But why doesn't the debugger stop at this line?

I have two issues. The first is that I want to make a textbox scrolling similar to how credits scroll. I don't want it to move on the form, just to scrolling the text down a line/pixel. I thought I could do it with the "Lines" element, but I'm not exactly sure how to execute it.
The other problem is with my flash screen. Right now I have it set so when a button is click, it goes onto the main form. I don't want to use the button but rather have it so if Enter is pressed at any time, it'll go to the main form. All the solutions I've tried to use involve the "e.Keycode" code, but for some reason its unavailable.

I have a simple function which tries to get a value from an Obout grid filter column, and if the value is empty, ignores it and moves on. For some reason this code ignore my catch block and always shows a System.FormatException when the input string is empty More bizarre, if I use visual studio's debugger and set a breakpoint on that line, the catch block functions normally (after I continue from that line). I have already confirmed that my Debug | Exceptions | CLR are not set to catch when thrown. I have also confirmed this same behavior in the production version.

I have 5 errors that come up every time I run my project They are all "A first chance exception of type 'System.ArgumentException' occurred in System.Drawing.dll"
I have try catch blocks around every piece of code I have written, and it does not seem to catch them, so I opted to catch the appdomain.UnHandledException.
That does not seem to catch them either If I step through the code line by line (several hundred lines so I hold down f8) it does not make the error...
Only when I run full speed.
I can only figure that I am accessing something maybe before an object is completely drawn, however how in the heck would anyone suggest I go about finding it, and why will my global event handler not catch them?

I am using BackgroundWorker to connect asynchronously to a database. Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]...
While my connection is being opened, I have a "Loading" animation show in a lblCalibration. Once it's connected, the animation stops successfully and shows the calibrated record that I am fetching from my db.
However, if there is an error while connecting to my db for any reason, it does not work. My app freezes. The reason is because I am trying to make a cross-thread call while trying to Catch the error in the DoWork event.[URL]..
but still cannot seem to make any progress. Does anyone have any tips or advice on how to properly catch the error and still run BackgroundWorker?
