I have a textbox and a submit button. The textbox is a date-entry field. Attached to it, I have a compare validator with the type set to "date". It does validate and show an error message.
Problem is, the user can still click on the submit button. I'd like to prevent that. If the user has entered something like 03/hello/2011, he or she should not be able to submit the form.
I have a form in my MVC application that in theory should submit data back to my database using a Repository class. However, when I submit the form ([URL]), the URL changes to where the form should be submitting to, which is fine ([URL]), but once it has been submitted, it should send the user to a confirmation page. From what I can tell, I'm moving through all my pages correctly until it comes to the submit, where it displays the form again but under /Admin/NewUser/Submit and the data is not inserted into the database.

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 am having trouble submitting a form with my program which is using the WebBrowser control.
WebBrowser.Document.All("follow").InvokeMember("click")
I tried this but it did not work. The result is that the WebBrowser displays "This program cannot display the webpage" error page. The problem I think, is that the page is using javascript when it comes to submitting the form.This is the code for the submit button:
<input type="button" onclick="submitIt()" value="Follow" name="follow"/>
And this is the javascript for the onclick="submitIt()"
function submitIt(){
document.formx.submit();
}
Is there any way to invoke that javascript submitIt() method through VB.net?
My compare validator is firing always even if it is greater and even if it is less.

I'm attempting to make an application which, upon entry of Amount to spend, Vendor, Employee, etc., a Purchase Order number is returned. My thought is that I'll simply let SQL pick the PO Number by setting it as an identity field. What I'm curious about, though, is how to directly query the database as opposed to using DataGridView or bound controls.Note that I have the following setup at this point.
DataSet --> BindingSource --> TableAdapterManager --> TableAdapter --> DataGridView
Where along that list would I inject my queries and how would I go about doing it?
My below code has to copy a table from access in to temp dataset and then i need to select some datas from the dataset... its workign fine up to copying in to dataset..but in the second part the query is not submitted.. im a beginner

My first thought was something odd with the date format, but we're using UK dates, last error was on 18th July, so the ValueToCompare gets set to 18/07/2011. I've set this manually using the debugger, and it worked fine.

I want to fill out forms, and I dont want to submit a POST url.
Instead, I need to access directly the DOM object, and somehow click or interact it programmatically.
should I use WebBrowser class ?
Can you show a sample code where text is entered into an input box, and the submit button is clicked ? ex) google.com
if I want to submit a large amount of text to my asp web page, do I need to worry about the text itself such as containing "&a=" that would mean another variable is being assigned for submitting data? Any way of not worrying about this? Or do I need to replace the & symbol everywhere in the test first if used?

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 have a tool window that I want to stay above the main application form, but not stay on top of all windows forms. Similar to the floating properties window for visual studio - it always stays on top of the main VS window, but if I select another program, like internet explorer, the floating properties window will be behind internet explorer.
What I have is an application that has several forms that may be displayed at the same time. I have a Messages form that displays messages generated by the code in the form, that gives the status of the application. Obviously, the user would not normally be working on this form, but they may want it to be visible to see the status messages from the program (File saved confirmations, etc). So, my two options right now are I can set the form to be on top of all other windows forms or, when the user clicks on the main application form, the messages form would be hidden by the main form.
