I need to make a javascript keyboard, as I am making a web app for touch screens. Is there a way that I can check which of the textboxes on my form had the focus when the button corresponding to the letter is clicked?

Set the onfocus event for each textbox to assign a variable to reference the box. When a textbox is focused the varible will then hold a reference for it so you could then alter the textboxe's value through the variable.

For example
Setting the current field:
<input type="text" onfocus="selected_field = this;" />

and a key board button could alter the field like this:
<input type="button" value="A" onclick="selected_field.value+='a';" />

Hi, thanks so much for this, it works perfectly. Out of interest, do you know of a way to prevent firing the event when a textbox is not selected? I have only just started working with Javascript, so I am not certain.

How could I install a application which is packed under .msi to client server?
I have read about .cab file too... what is the differences between the two?
I wish to make a silence install so should I go with .msi or is it possible to do it with .cab since it seem much less troublesome.

Common functions

Hi guys,

I've used PHP quite a bit before, and I'm now moving over to ASP.

In PHP, I would create a common functions file called functions.php, and use require('functions.php') at the top of every page.

I am having trouble trying to replicate this in ASP.

In a single page scenario, I have this code, which queries a database:

<br />
Dim Conn 	'Create the ADOBD connection object<br />
Dim rs		'Create the recordset object<br />
<br />
set conn = server.CreateObject ("ADODB.Connection")		<br />
Conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & server.MapPath ("Rental.mdb")<br />
<br />
set rs = server.CreateObject ("ADODB.Recordset")<br />
<br />
<br />
rs.Open "SELECT [BALANCE] FROM [MEMBER] WHERE [MEMBERID] = " & session("memberID") &"", Conn

So, I created a functions.asp page, and placed all code EXCEPT the rs.open line, into it. That page looks like this:

<%<br />
Function SetupConnection()<br />
<br />
	Dim Conn 	'Create the ADOBD connection object<br />
	Dim rs		'Create the recordset object<br />
<br />
	set conn = server.CreateObject ("ADODB.Connection")		<br />
	Conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & server.MapPath ("Rental.mdb")<br />
<br />
	<br />
	set rs = server.CreateObject ("ADODB.Recordset")<br />
<br />
End Function<br />
%>

I then placed this in the original page, above the rs.open line...

SetupConnection()

When calling the original page, I get:

Object required: ''
/account_main.asp, line 11

Line 11 is the rs.open line.

Am I completely missing the point here? The only thing I can assume is that it's something to do with the scope of variables.

ViewState problem...

In one form I save a variable in a view state like so:
ViewState["Color"] = "red";

I then call Response.Redirect(nextPage.aspx)

In the page load function of nextPage.aspx I try and read the variable using this:
string sColor=(string) ViewState["Color"];
but there is nothing there!

What am I doing wrong?

thanks

Brian

Hi Brian. ViewState is maintained for one page and its postbacks. When you redirect to another page, a new ViewState is generated.

In your context, you may want to set a cookie rather than use ViewState, or use a Session variable: Session["Color"] = "red";

Thanks Mike.

I did just that and things are working.

Perhaps you can answer this question for me

If I defne an aspx page with html controls, can I use code behined file to handle the code for those controls? This would mean that the controls are handled client side...

Hi Brian. The code-behind file (and the .aspx file for that matter) is compiled and executed server-side only. You can declare standard <html> controls with the runat="server" attribute to access them server-side. Here's a simple example:

<%@ Page Language="C#" %>

<script runat="server">

  void Page_Load(object o, EventArgs e)
  {
    myHeading.InnerHtml = "This is the Heading";
    myText.Value = "Default Value";
  } 

</script>


<html>
  <head>
    <title></title>
  </head>
  
  <body>
    <form runat="server">
    
      <h3 id="myHeading" runat="server" />
      
      Here is a standard HTML text box:
      <input type="text" id="myText" runat="server" />
    
    </form>
  </body>
  
</html>

If you want to manipulate html controls client-side, you'll need to look at javascript for that.

Are you using a third party COM component todo the uploading? I'm assuming this is classic ASP (not asp.net). Usually the component doing the uploading has methods to get access to the form variables.

If I understand you correctly you need to use the Server.MapPath method.
This will turn your relative path into an absoulte path.

I think you need to set the expiration (which is a header) on the page. I think something like Response.Expires = 0 is what you are after.

You can use client-side script to set the focus - look here for an example: http://support.microsoft.com/default.aspx?scid=kb;EN-US;316719[^]

You might consider, instead of using document.all('txtInput1').focus() in the example, try document.getElementById("txtInput1").focus().

JavaScript variable from ASP form?

tantiboh30-Apr-05 6:53

30-Apr-05 6:53

Here's my situation. I've got an ASPX page that needs to be refreshed with new content every few seconds, but that amount of time is variable. I'm sending that variable to the page from the server-side application on every refresh. That way, theoretically, the page can automatically refresh when that variable amount of time is elapsed and thereby get a new amount of time to count down.

Setting up a JavaScript reload function is easy enough, but I can't find a way to get that ASP variable into the Javascript, as the JavaScript seems to be able to only access HTML form components and not ASP form objects.

So, I either need a way to get an ASP variable into the JavaScript, or I need a different client-side script that can actually get that variable from an ASP control and is still capable of causing a PostBack like JavaScript can. Any ideas?

Thanks for your help!

Well if you think about it, all the server is doing is outputting text, whether that text is HTML, javascript etc.
So you could output something like this:

<javascript block="">

setTimeOut(<%= Some Variable calculated on the server%>);

<javascript block="">

This would be sent to the client like:

<javascript block="">

setTimeOut(500);

<javascript block="">

Of course this is oversimplified, you could create custom controls that are a little more elegant and reusable.

1-> by using request("variablename").
