How long can this postback actually take? A postback should just be a quick flash on the screen. You would not have time to show the user a message.

Unless there is a file upload....
Well you said you're using vbscripting. I don't know if you ment "vbscript" or actual "vb".
Regardles, that kind of popup message would be handled with client side script (javascript/vbscript) and not in the backend.
Just make a div with the "please wait message" and mark it hidden. Then when you want, set the z-index and make it visible.
It doesnt take long to refresh the page, but meanwhile, I do not want the users to input the data in the form. There would like to post a "please wait" message.
If you have any samples, kindly let me know. And Yes I am using VB with ASP.net.
Thanks you both.

As Mentione before try to this way
<body bottomMargin="0" onbeforeunload="busyBox.Show();" leftMargin="0" topMargin="0" rightMargin="0">
<iframe id="BusyBoxIFrame" ondrop="return false;" style="WIDTH: 500px; HEIGHT: 8px" name="BusyBoxIFrame"
frameBorder="0" scrolling="no"></iframe>
<SCRIPT>
var imagePath = "../images/";
// Instantiate our BusyBox object
var busyBox = new BusyBox("BusyBoxIFrame", "busyBox", 4, imagePath + "imagename", ".gif", 125, 255, 185);
</SCRIPT>
Forgot this function....
Change it as per requirement
function BusyBox(id, varName, imageCount, imageNamePrefix, imageNameSuffix, imageDelay, width, height, url)
{
// Initialize object
this.id = id;
this.ImageCount = imageCount;
this.CurrentImageIndex = 0;
this.ImageWidth = 0;
this.ImageHeight = 0;
this.ImageNamePrefix = imageNamePrefix;
this.ImageNameSuffix = imageNameSuffix;
this.ImageDelay = imageDelay;
this.DivID = "BusyBoxDiv";
this.ImgID = "BusyBoxImg";
this.Enabled = true;
this.Width = width;
this.Height = height;
// Retain the name of the instantiated object variable so that we can animate
// using the setTimeout statement
this.VarName = varName;
// Allows us to stop the animation with clearTimeout(), should we ever want to
this.timeout_id = null;
// Cache (pre-load) images
this.CacheImages();
// Url to the page containing the busy box.
this.BusyBoxUrl = url;
// Get reference to the IFrame object
this.IFrame = document.getElementById(this.id);
// Hide the busy box
this.Hide();
if( this.BusyBoxUrl )
// Load the busy box contents using a custom layout page.
this.LoadUrl(this.BusyBoxUrl);
else
// Load the busy box contents using the internally defined layout.
this.RenderContent();
// If this browser does not support IFRAME tags then disable this control. The
// next version will implement the use of a DIV instead of the IFRAME tag;
// even though there are a couple minor issues with using DIV tags.
if( !frames[this.id] )
this.Enabled = false;
}
Well here is a quick example:
Create a DIV: (You should probably give it height/width/spacing and all that good style stuff too) -
<div id="WaitingMessage" style="display:inline; visibility: hidden; z-index:0;"> Please wait for server to respond </div>
-
-
function WaitMessage(boolval)
-
{
-
if(boolval)
-
{//set visibilty to "visible" (you may need to adjust z-index as well)
-
var obj= document.getElementById("WaitingMessage");
-
obj.style.visibility = "visible";
-
obj.style.zindex=5000;//make it aboveeverything
-
}
-
else
-
{//set visibility to "hidden" (you may need to adjust z-index as well)
-
var obj= document.getElementById("WaitingMessage");
-
obj.style.visibility = "hidden";
-
obj.style.zindex=0;//make it below everything
-
}
-
}
-
Call WaitMessage(true); to show it and WaitMessage(false); to hide it
