Hi Folks,
I've recently experienced a major problem with a website I recently uploaded.
The problem is this......
I implemented a pretty standard thumbnail generation utility for uploaded images which works fine when tested on my local machine and also when I browse the website online from my local machine.
It doesn't work when I browse from other machines and also any thumbnails generated on the server when browsed from another machine do not show up on my machine!
I'm at a loss to explain this. Surely the code should be universal since it is processed by the server, not the local machine?
The only thing I can think of is that somehow the browser communicates with the server in a specific way based upon the installed framework that is on the browsing machine causing the server to run the code in a particular way. This goes against my understanding of the browser server relationship though.
My code is the following
<code>
''' <summary>
''' Resizes images to the specified size.
''' </summary>
''' <param name="fileStream">The file stream.</param>
''' <param name="fileName">Name of the file.</param>
''' <param name="finalPath">Where to save the resized image</param>
''' <param name="maxWidth">Maximum Width</param>
''' <param name="maxHeight">Maximum Height</param>
Public Shared Sub ResizeAndSave(ByVal fileStream As IO.FileStream, ByVal fileName As String, ByVal finalPath As String, ByVal maxWidth As Integer, ByVal maxHeight As Integer)
Using originalBMP As New System.Drawing.Bitmap(fileStream)
' Calculate the new image dimensions
Dim width As Integer = originalBMP.Width
'actual width
Dim height As Integer = originalBMP.Height
'actual height
'resize as landscape or portrait based on dimensions.
Dim tempWidth As Integer
If height > width Then
tempWidth = maxHeight
maxHeight = maxWidth
maxWidth = maxHeight
End If
Dim widthDiff As Integer = (width - maxWidth)
'how far off maxWidth?
Dim heightDiff As Integer = (height - maxHeight)
'how far off maxHeight?
'figure out which dimension is further outside the max size
Dim doWidthResize As Boolean = (maxWidth > 0 AndAlso width > maxWidth AndAlso widthDiff > -1 AndAlso (widthDiff > heightDiff OrElse maxHeight.Equals(0)))
Dim doHeightResize As Boolean = (maxHeight > 0 AndAlso height > maxHeight AndAlso heightDiff > -1 AndAlso (heightDiff > widthDiff OrElse maxWidth.Equals(0)))
'only resize if the image is bigger than the max or where image is square, and the diffs are the same
If doWidthResize OrElse doHeightResize OrElse (width.Equals(height) AndAlso widthDiff.Equals(heightDiff)) Then
Dim iStart As Integer
Dim divider As [Decimal]
If doWidthResize Then
iStart = width
divider = Math.Abs(CType(iStart, [Decimal]) / CType(maxWidth, [Decimal]))
width = maxWidth
height = CInt(Math.Round(CType((height / divider), [Decimal])))
Else
iStart = height
divider = Math.Abs(CType(iStart, [Decimal]) / CType(maxHeight, [Decimal]))
height = maxHeight
width = CInt(Math.Round(CType((width / divider), [Decimal])))
End If
End If
Using newBMP As New System.Drawing.Bitmap(originalBMP, width, height)
Using oGraphics As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(newBMP)
oGraphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias
oGraphics.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic
oGraphics.DrawImage(originalBMP, 0, 0, width, height)
newBMP.Save(String.Format("{0}{1}x{2}_{3}", finalPath, maxWidth, maxHeight, fileName))
End Using
End Using
End Using
End Sub
</code>
I'm seriously considering wiping my machine and reinstalling thye operating system, visual studio et al to see if there are bugs in my copy of the Net framework. I'm running a Release Candidate of Windows 7 (daft I know) so I wonder if that is the issue.
Any help would be greatly appreciated.
Thanks in advance

Have you checked the compatibility mode settings on the browsers? I highly doubt that it is a bug in the framework
Also, you may want to review the How to get answers post at the top of this forum. "Cracking up" is not an appropriate or descriptive subject line.

Changed.
Good point. It's been a long night and my brain's not what it should be. 
I'm not saying that there's a bug in the framework. just that maybe somethings got corrupted on my computer. Even that's a shot in the dark.

Without going through all the code, the fact it works on your machine but not others suggests a couple of possible causes.
First, you may have something pointing to a local file, rather than a server version. Since the file exists on your machine, it will work, but not on others. Try renaming the folders you created the original web site in, and see if it still works.
A second possibility is that your thumbnail generation isn't working quite correctly, but having tested it on your mahine, you now have the required thumbnails in your cache, so they load OK. Try clearing your browser cache and trying again.
As mentioned above, it's unlikely to be a framework problem, so I'd view that as a last resort after checking more mundane causes.

Well..... A wee bit of a kip and a coffee later the answer was staring me in the face.
There was a bug in the thumbnail code. I wasn't passing the temporary variable Tempwidth down to MaxWidth so filenames weren't matching saved records.
I was also assigning the filepath for the images a static value rather than returning a dynamic value generated by landscape or portrait images.
I turned it into a function and returned the value back and that fixed everything.
Thanks to you both for your comments. It just takes a few sensible calm words to fix most problems.
Cheers!

You need to read the documentation provided by your web hosting company, as they all have slightly different setups. Check their main web site for anything like a "Support", "Help", "FAQ" or "Forums" link, and look around there for instructions on which folders to use.
Also make sure you have the correct file extension - .htm or .html, and if you're not giving the full path to a file, that you have and index or home file.
If you're really stuck, email their support address, or raise a ticket in their support system, and they should get back to you with an explanation. Most hosting companies are fairly quick to respond (although it's now the weekend so you might have to be patient).

I have a Flash movie on a web page and I want to send parameters to it with JavaScript to have it go to a selected frame. The AS3 code receives its information via an ExternalInterface API. The following code parses the URL argument (?page=x) and I want to send the value (x) to Flash. Unfortunately, when creating the objMovie variable, it is always undefined, therefore getFlashMovie is undefined and Flash never receives the callback.
Thinking that it was because the flash movie is not loaded yet, I created a button to call callToActionscript, and when I click the button, I get the same error. (getFlashMovie("myFlashMovie") is undefined)
I am not seeing what I'm doing wrong (mainly because I'm a newbie...). Please enlighten me.
Also, if (params) always returns true, whether there are parameters or not. I don't understand that, either.
The code follows:
<script type="text/javascript">
$(document).ready(function() {
var params=getQueryParameters();
if(params) {
callToActionscript(params[0]);
}
});
function getFlashMovie(movieName) {
var isIE = navigator.appName.indexOf("Microsoft") != -1;
var objMovie = (isIE) ? window[movieName] : document[movieName];
alert(objMovie);
return objMovie;
}
function callToActionscript(page)
{
var myMovie=getFlashMovie("myFlashMovie").sentToActionscript(page);
}
function getQueryParameters() {
var query = window.location.href.split('?')[1];
if(!query) {
return { };
}
else
{
var param = query.split('=');
}
return param[1];
}
</script>

I'm not excatly sure what you mean by this, but if you subscribe to the onblur event of the textbox you can display an alert window.

hi man , i know that , but how i can allow dialog appear to particular user? for example
i type ur nick in text box and say "Hello!!!"and click submit button , then a dialog warn appear for u

re7et_3esh wrote: allow dialog appear to particular user?
Still not clear here.
1) In the code behind you check which user the page is being rendered for than attached the javascript event to the textbox as appropriate
or
2) Make an Ajax call from the onblur event to determine if the alert box should be displayed or not
