Hi, everyone!

In the parent page, I want to pop up a child page at the
specified location of the parent page and have a specified
width and height.

How to use JSP to do it?

Cheers,
George

George,

I the result you want can be achieved by using javascript on the client.

Have a look at the window object: showModalDialog and showModelessDialog and using an IFrame in the pop-up child window. (I recommend the IFrame because it allows you to treat the content like a regular web page but the entire child window can be made modal to the parent window...

I hope this helps.

Hi, everyone!

I noticed that in java.sun.com, for each type
of OS, there are two materials deals with Java
to download, they are JRE and JDK.

My question is, what is the difference between
JRE and JDK?

If I just want to Programming with Java, I think
I only need to download JDK. Am I correct?

Cheers,
George

The JRE is the Java Runtime Environment and the JDK is the Java Development Kit.

You would use the JDK to write and run software and you would use the JRE to run it.

JDK (Java Development Kit) is what is needed to develop and deploy java application i.e. a kind-of-interpreter/compiler for Java since it contains the compilers and debuggers. Its needed by the Java Developer/programmer.
JRE(Java Runtime Environment is to be used by the Java application user and consists of the Java Virtual Machine, the Java platform core classes, and supporting files - hence JRE is neede d to run Java Application

If it is applied to Windows and VC++, it is even better.

Any suggestion ?

calling a subprocedure

Re: calling a subprocedure

19-Sep-02 2:04

i am coding for an online survey (in VBScript). on the click of the submit button, i wish for a function to be called which will check to see have all fields been filled out and if not, a message box to appear. here is a snippet of the code:
...survey....
<%
Sub Validate_onClick
'ERROR CATCHING
'question 2
If (Request("People") <> "") AND (Request.Form("Specify") <> "") Then
MsgBox "Please enter value for Q2"

End if

End Sub
%>

however, the code is not working as the message box is not appearing...what am i doing wrong?
thank you!

You are confusing client side with server side.

When you use the <% and %> block declarations you are specifying that all code within that block is processed on the server and NOT sent to the client as is.

So in fact when you have the onclick="Validate()"> code firing off there is not function Validate to call because it was "left" behind on the server. Also you cannot get server side code to show an alert box on the client side directly.

So, this is how you do what you want to do.

<script language="javascript>
function Validate()
{
//ERROR CATCHING
//question 2
if (document.People == "" || AND document.Specify == "")
{
    alert("Please enter value for Q2");
    return false;
}else{ return true;}
}
</script>

<input TYPE=RESET name="btnAdd" value="Reset" onclick="return confirm('Are you sure you wish to reset?');"><input TYPE="submit" name="btnAdd" value="Submit" onclick = "Validate()">

So basically you are mixing up your client side code (JavaScript) and your server side code (ASP.)

IHTMLAnchorElement --- Help please

Gegzy19-Sep-02 0:55

Hi
Scenario:
I have a web page which is updated at very regular intervals. This page contains various links which change throughout the course of the day. My project is using MFC.

Problem:
I am using IHTMLElementCollection to get a list of anchors (<a>) which is working OK. I can obtain each anchor from this collection by assigning to IHTMLAnchorElement.

I need two bits of information. Firstly, the HREF from each anchor (which I can easily obtain by calling GetHref()).

The second piece of info I need is the text that the HREF is associated with...

For Example
.
.
<a href="www.sample-link.com">CLICK ME NOW!!!</a>

A call to GetHref() returns me "www.sample-link.com". What I'm also after is the text "CLICK ME NOW!!!"

Any ideas on how to do this?

Thanks In Advance

Tiz OK!

I've sorted it out (I think)

When getting the anchor to the current element using IHTMLAnchorElement, I needed to use IHTMLElement::GetInnerText() of the same element.

Worked a treat!

Would like some advice to see if this is the correct way or if there is a better way.

Thanks!

Hi
I'm running the SQL Desktop engine, and I'm try to fill a dataset with some data.

Now I get this error.

Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'LEPPIE\ASPNET'.

Source Error:

Line 29: {
Line 30: // Put user code to initialize the page here
Line 31: sqlDataAdapter1.Fill(userDataSet1);
Line 32: DataGrid1.DataSource = userDataSet1;
Line 33: DataGrid1.DataMember = "Users";

Source File: d:\inetpub\wwwroot\XXXXX\webform1.aspx.cs Line: 31

This I do in the PageLoad Event.

How do I give the necesary right to the ASPNET user to access SQL? Or is this a no-no? I'm very new to the web side of .NET and I'm not sure if this is the correct way to do it either Confused | :confused:

Any help appreciated Smile | :)

Re: error handling and message boxes

i am coding in VBScript. i am coding for an online survey. for error handling (eg if the user forgets to fill out a field), is it possible to ensure all fields have been filled out BEFORE clicking the submit button? i wish for the user to be notified via a MESSAGE BOX, how would i go about this(using VBScript)?
thank you!

This doesn't work very well using VBScript - I've been down this rocky path before. However, contrary to popular opinion, VBScript & good ol' pain in the butt Javascript work very nicely on the same page.

Don't kill yourself trying to do something we all believe should have been integrated nicely into VBScript but wasn't. Just build your whole page in VBScript, but get your submit button to call a traditional javascript validation function.

You will sleep better this way Cool | :cool:

Re: retaining state for checkboxes and radio buttons

17-Sep-02 23:03

i have a series of checkboxes and radio buttons. when the user submits the information it goes to another page, where it is validated. however, if there is a mistake in the data, a hyperlink brings the user back to the original page. however, the checkboxes and radio buttons are back to their default state - how do i fix this? (i have used the session variable for the text boxes). here is an example of the checkboxes and radio buttons:

Instead of going back, make your script generate html output containing a new form with the previously entered data filled in. That way you can also easily highlight the fields that contained errors
