So are you saying that i should normalize the http://www.example.com/dir to http://www.example.com/dir/ means i must add a trailing slash to it.
|
|

|

It works either way, but if you know that it's a folder, there is no reason to write the url without the trailing slash.

Thanks

Not being funny but you have even tried to solve this yourself if you had it would have taken 10 minutes.
I suggest you look at this:
http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.imagebutton_members.aspx
and set this www.msdn.com in you favourites it will save you and us a lot of time

Hi Dan,
I suppose to check if the image if it will display or not. And if won't display the image it will be changed programmatically into an image - blank.jpg
Please see my source code below.
ImageButton1.ImageUrl = "~/Images/Item_Thumbs/image1.jpg"
ImageButton2.ImageUrl = "~/Images/Item_Thumbs/image2.jpg"
ImageButton3.ImageUrl = "~/Images/Item_Thumbs/image3.jpg"
If ImageButton1.ImageUrl Is Nothing or String.IsNullOrEmpty(ImageButton1.ImageUrl) Then
ImageButton1.ImageUrl = "~/Images/Item_Thumbs/blank.jpg"
End If
If ImageButton2.ImageUrl Is Nothing or String.IsNullOrEmpty(ImageButton2.ImageUrl) Then
ImageButton2.ImageUrl = "~/Images/Item_Thumbs/blank.jpg"
End If
If ImageButton3.ImageUrl Is Nothing or String.IsNullOrEmpty(ImageButton3.ImageUrl) Then
ImageButton3.ImageUrl = "~/Images/Item_Thumbs/blank.jpg"
End If

Hey
your logic seems fine as does how you are implementing it. The one thing I would consider is rather than loading blank.jpg I would just set the appearance of of the image button to your blank colour as the code will not have an image and it will not rely on an image being there. If the image isnt there it will display funny (possibly) so is not terrible but wont look all that professional.

But how can I do that?
I mean, it can be set to visible = false, but at first is how can I detect if the ImageUrl is not showing the image.
If there's definite code or way on checking the imagebutton.imageurl if the image is not showing then that would be fine.
It's just like doing a code for example:
If ImageButton.ImageUrl = Image not showing then
ImageButton.Visible = false
End If
Something like that. The only thing is how to check the image if it shows
Thank you Dan for sharing your ideas

Ahhh I see. Well if the imagebutton is not showing an image it means that it hasnt found the image or cant read it etc so what you would have to do is check the image file exists. It sounds to me like you are going to a lot of trouble to make sure an image button contains an image - just make sure that the image url always points to a valid image rather than doing all this checking or before each load check the image exists if it doesnt then hide the button.

Just downloaded the Apple Safari web browser and playing around. Two things I am bit stuck. If somebody could help out, it would be great:
1) Any Javascript Debuggers like Venkman for Safari? Neither does Visual Studio integrate nor Venkman for FireFox is able to understand Safari integration!! 
2) And BTW, why is the Proxy: Change Settings always disabled and is not available for configuration?

Hy,
I'm trying to develop a new plugin to Mozilla (etc.) browser, but before writing a single line of code, I've encountered a problem.
Ok, I know that to develop for Mozilla, I should do the coding under GECKO SDK and stuff, but I know nothing about how should I set up de enviroment to work with VS2005.
I've already read quite a lot of google, even mozilla's developer sites, but I'm confused.
Could anyone please provide me a step-by-step tutorial about setting up Gecko, XUL-runner - if needed - and any other things I might use.
Ps: Sorry if my question is offtopic, but I haven't found the proper one.
Thanks in advance :

Try to think this code through, for a value of 32. Both tests actually succeed, and so you'll get your alert ( what a pain, I'd suggest removing it ).
Try this:
function checkIt(event)
{
var charCode = (event.which) ? event.which : event.keyCode;
return (charCode == 32 || charCode == 13 || (charCode >= 48 && charCode <= 57));
}
I assume if you want the alert still, you can rework this code accordingly.

This code works fine...but when i am entering some text in the desired textbox and hitting enter then the page posts itself and return error...
You checked the value of enter key in the function then how can this go wrong...
when i press enter key the control should be in the same textbox...
but it is not working ..other key works fine...
thanks for the reply...

OK, you didn't say that.
You need to make sure there's no default button, so that enter does not cause postback. Your code also is not going to 'work fine'. It will work fine so long as you don't press any other key that has a value between 32 and 46, or whatever it was. The implimentation is plainly flawed, even if you've failed to notice.

I use this PHP class for image manipulation on the server.
www.verot.net[^]
Here is some sample HTML to get the files to the server.
<br />
<fieldset><br />
<legend>Image upload</legend><br />
<p>Pick up an image to upload, and press 'upload' </p><br />
<form name="logo_form" enctype="multipart/form-data" method="post" action="logo.php" /><br />
<p><input type="file" size="32" name="my_field" value="" /></p><br />
<p class="button"><input type="hidden" name="action" value="image" /><br />
<input type="submit" name="Submit" value="upload" /></p><br />
</form><br />
</fieldset><br />

Try this
Image Upload
1) Find name of image
Img1=doc_file.FileName.ToString.Trim()
2) Replace blank space with “_”
Img1=Img1.Replace(“ ”,”_”)
3) Use Substring
Img1=img1.Substring(img1.LastIndexOf("\") + 1, img1.Length - img1.LastIndexOf("\") - 1)
4) Find Extension
ext1 = doc_file.FileName
5) ext1 = ext1.Substring(ext1.LastIndexOf(".") + 1)
6)Check if ext is blank or not.if not then concatenate ext with “.”
If Trim(ext1) = "" Then
ext1 = ""
Else
ext1 = "." & ext1
End If
7)Send ImageName as blank in database
8)Take new String variable
9)ImageNew=”image_” & ret.tostring & ext1
10)Check if ext1 not equal to blank
ImageNew=”image_” & ret.tostring & ext1
Then use update command
update tblImages set ImageName='" & sImg_name_new & "' where ImageId =" & ret
11)Then use Upload Function
