You might want to tell us what kind of server your checking this username and password against. We'll need alot more information than this to tell you what you need to do.

Hi all,
Hope this is an easy one...
Here is the problem:
In the code-behind, I have dynamically built a series of tablecells each with a Literal control containing an image.
----------------------------------------------------------------------------
dim litCont as New System.Web.UI.WebControls.Literal()
dim strValue as string = "testString"
dim contStr as string = "<img name='pix1' onMouseDown='doMouseDown("& strValue &")' src='images/pix1.jpg' />"
litCont.text = contStr
objCell.Controls.Add(litCont)
----------------------------------------------------------------------------
When the user clicks on any of the images it fires the JavaScript function doMouseDown() which receives a string parameter.
QUESTION: How could I then pass the value of the str parameter to the Label Control ("legend") in "Form1" so that the label may be updated?
I have simplified the structure of the form
----------------------------------------------------------------------------
<html>
<head>
<script language="javaScript">
<!--
function doMouseDown(str){
// code stuff here
}
-->
</script>
</head>
<body >
<form id="form1" runat="server">
<asp:table id="mainTable" runat="server" >
<asp:tableRow runat="server">
<asp:tableCell runat="server">
<asp:label id="legend" runat="server" />
</asp:tableCell>
</asp:tableRow>
</asp:table>
</form>
</body>
</html>
------------------------------------------------------------------------
Thank you

Your question would be better handled in the ASP.NET Forum[^]. Your question has nothing to do with VB.NET. The solution would be based entirely in JavaScript and the HTML that's generated by the asp tagged controls (Hint, Hint!)

Hello Dada,
Thanks for your help.
<i>document.getElementById('legend').innerHTML = str;</i>
The line above is actually what works for me in this particular situation.
Anyway, thanks a lot for taking the time to help.
Cheers,
Pyb

I implemented a keyboard based tab system in my program. When you are in a control if you press "Enter" then the next control is focused as if you have pressed tab key. What the problem is that when you are in a DateTimePicker or TextControl and press "Enter" a "Dong" sound is heard which is like an error indicatior. How can I get rid of this sound?

Hi
Short time before I had the same problem. This worked for me. The
e.Handled = True
disables the sound.
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
If e.KeyChar = Chr(13) Then
Me.SelectNextControl(Me.TextBox1, True, True, False, True)
End If
e.Handled = True
End Sub

In VB 6, one can easily add in the API Viewer and then load up WIn32 API functions and constants in the viewer, so that it can be easily copy and pasted into our applications.In VB.Net, where can I find the APIs and its constants, so that I can cut and paste into my application.

There is no such app that and database that comes with VB.NET. Your best best for something like this is http://www.pinvoke.net[^].

Ok I've created a class that adds buttons, textboxes, checkboxes etc at runtime. I can move all these objects etc. What I would like to do is make the program smart. Basically what I want to is beable to add many buttons, textboxes etc (already working) and link them up ie.
if I click on button1 it writes to a textbox that I specify, which is on the child form
if I click on button2 it opens up a file dialog
if I click on button3 it creates a new Database
if I click on button4 it opens up another form.
also if I want to change these configurations for the buttons I can do so with in the program. Basically you control what you want to do like in vb.net

I dunno for what reason you want to do so, but here is one way!
first make a string array with dimention of the total commands:
ReDim Action(iButtonsCount)
for each time creating a new button.
then set the array value to some command to be done, e.g.
Action(iButtonsCount)="OpenFileDialog"
then in click button event add:
<br />
Private Sub arrButton_Click(Index as Integer)<br />
Select Case Action(Index)<br />
Case "OpenFileDialog"<br />
'.....<br />
End Select<br />
End Sub<br />
Also if some of your commands need some parameters, you can make the array 2D or more, and set the parameter in the second column in the array.
I hope this will help.
