So I'm developing a Windows Forms Application in Visual Basic 2010. The user searches for data and fetches results, updates fields and some other CRUD operations. I want to provide a user input validation. Usual stuff i.e. some fields need to be always numbers>0, others need to be non-empty in order to avoid Null access on some objects and others just need to be some fixed strings.

I have a webbrowser and on a form I need it to fill text. The problem is, in order for the submit button to activate, you have to atleast type in 1 letter for it to update and make it send. The problem is when I do document.getElementById("p1").innerHTML= "SSSS" it works but it wont update the submit button to allow me to submit the form. What should I do?
View 2 RepliesI have a view with a few checkboxes that can be selected or unselected. I'd like to always register any change in a checkbox, without the use of a submit button (the user could forget to do it, and it would waste time). So, is there a way to handle this inside the view? Up to now, I've only used the controller to do that job.

I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.

I am working on my new server now. I have created very simple page which has a for loop on code behind. If i dont define "i" as integer before the loop, i got this error

But, i can use for loops without declaration of "i" before loop.
For i = 1 To 10

Hi everyone. I havent used VB for about 4 years so I am trying to refresh my memory for a project I am doing. I want to link it to an Access database and have the following code:
[
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTest.Click
Dim sqlstring As String
Dim conconnection As New ADODB.Connection
Dim cmdCommand As New ADODB.Command
Dim rstrecordset As New ADODB.Recordset
conconnection.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _
App.Path & "" & "database1.accdb;Mode=Read|Write"
conconnection.CursorLocation = adUseClient
conconnection.Open()
With cmdCommand
.ActiveConnection = conconnection
.CommandText = "SELECT * FROM tblRegister;"
.CommandType = adCmdText
End With
With rstrecordset
.CursorType = adOpenStatic
.CursorLocation = adUseClient
.LockType = adLockOptimistic
.Open(cmdCommand)
End With
]
However when I run the program I get the following error messages:
error BC30451: Name 'App' is not declared.
error BC30451: Name 'adUseClient' is not declared.
error BC30451: Name 'adCmdText' is not declared.
error BC30451: Name 'adOpenStatic' is not declared.
error BC30451: Name 'adUseClient' is not declared.
error BC30451: Name 'adLockOptimistic' is not declared.
Is there some sort of Add-In or reference I need to add? I can't remember how I did it last time!
Thank you
Amy

View 1 RepliesIn my .NET porject, I have to run a lot of validation on 4/5 fields. This validation checks if certain fields have errors, for example: the name field is not allowed to have numbers or symbols. If all these checks are passed, I need to execute a SQL query to pull some data out of the database. I could have it with a lot of nested IFs, and run the function at the end once it passes them all, but this will translate into about 12 nested IFs, and it seems a really bulky way to do it. I have also thought about setting a boolean value after every check, and if the value is 1 then don't run the function, else do. But of course this gets overwritten by other checks that pass.

I have a form containing a date textbox and a submit button and a close window button. The date textbox onblur calls a javascript function which checks for date validation and some other logic and displays some alert messages. The date on the textbox is always selected and onfocus. My problem is when I try to click the close window button with/without changing the date the alert messages from the onblur logic are displaying and I am unable to close the window. I tried using onchange instead of onblur but onchange too works when a control looses focus. it works fine when I donot change the date but when I change the date and hit the close window button it too displays the alert messages and the window does not close. Please suggest me what will be my best option.
