well, *something* has to handle the request - if not your custom handler then .NET itself, so as long as you pass it straight back if no editing is required I wouldn't worry too much...
If [condition] Then
' amend image
...Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg)
Else
' send original image straight to browser
context.Response.ContentType = "image/jpeg"
context.Response.WriteFile([FilePath])
End If
Otherwise, if you can separate your images into different folders such that all those that need amending are all in a particular folder then you can re-write the path="*.jpg" attribute in your web.config accordingly...

Can the ASP.NET cache be purged from a HttpModule? I need the code for each page to rerun after I purge certain data that I track in a HttpModule. However when I attempt to get the cache (HttpRuntime.Cache) it doesn't seem to contain anything. However, when debugging it, the code in the page does not get executed the second time through and perfmon asp.net total cache shows there are items. I am using the CommerceAD (IBuySpy.com) for my testing.
Does anyone know what is going on or how to purge this cache so that the page code will run the second time through? I would prefer to just be able to purge the cache when I need torather than disable it entirely.
Thanks.

I have extracted controls such as text boxes, buttons, grids etc from the page and embedded them into a user control (ascx file) which is also placed on the same page! Now I'm presented with a dilemma...i'm not sure when the user clicks the button, lets say located on the page itself, I'm suppose to go inside the user controls (which is also on the same page) and make stuff happen with the controls inside this user control such as put the focus on a text box, or clear the text box's value and things like that. I have asked this question earlier, and someone told me that I can create public properties in the user control and call them from the page by using FindControl method. Well apparently this isn't working for me.
Can someone please tell me how do I use delegates to accomplish this (if possible). or if there's a better and easier way to do this kind of stuff. I'd appreciate it. Thanks

Hi friends,
I am making any saving on any web page. In code block, I am writing Response.Write(Apple.Quantity) after saving code. It turns me previous apple.quantity before recording , not current apple.quantity. How can I solve this problem?

Hi,
Please paste your code and try to check if you are not initializing the value on page load.

Hey guys, as I mentioned in the subject line...I'm having trouble interacting between the page level controls and the User Controls (asxc files) that I have. I have devided the page into five sections
<table>
<tr> General drop downs and buttons are located here</tr>
<tr>
<td>
First User control
<td>
<td>
Second User control
</td>
</td></td></tr>
<tr>
<td>
3rd User control
</td>
<td>
4th User control
</td>
</tr>
</table>
Now ititially I wasn't using these user controls, so all the controls that are now present inside these user controls were directly located on the page. It was easier to pass into around and do things such clear the entire form and other things since all the controls were right there on the page. But now that I have extracted those controls such as text boxes, buttons, grids etc and embedded them into these user controls, I'm presented with a delliema...i'm not sure when the user clicks the button, lets say on the top level (the buttons that are located on the page itself), I'm suppose to go inside the user controls and make stuff happen such as put the focus on a text box, or clear the text box's value and things like that. I have asked this question earlier, and someone told me that I can create public properties in the user control and call them from the page by using FindControl method. Well apparently this isn;t working for me. Can someone tell me how do I use delegates to accomplish this if possible. or if there's a better and easier way to do this kind of stuff. I'd appreciate it

Hello!
The control is a object that is located in the page class.
that is,
you can access methods in the control by referencing them as:
Mycontrol.MyMethod() from the page.
to find buttons and/or other control in the ascx, use Mycontrol.FindControl("MyButton").

Hi Andreas, thanks for the response... I actually tried something similar to this earlier...but it won't find the control when I pass in the ID of, for instance the button FindControl("MyButton").
I was reading somewher that delagates could be used to pass information around in for instance a situation like this. Can someone shed some light on this please.

Hi,
Use the following control to get the control rather than FindContol
public static Control GetControlByID(string id, Control ctl)
{
Control retCotl;
for (int i = 0; i < ctl.Controls.Count; i++)
{
retCotl = ctl.Controls[i].FindControl(id);
if (retCotl != null)
{
return retCotl;
}
else
{
retCotl = GetControlByID(id, ctl.Controls[i]);
if (retCotl != null)
{
return retCotl;
}
}
}
return null;
}
Some how i feel Control.FindControl is buggy and doesnot always get the control. Use this one to avoid the problem

Hi,
If you just need to clear textboxes and put focus on then , you can use javascript to accomplish the task i dont know why you want to clear textbox in a server side event.
If you have to call server side code use reflection to invoke method and properties of the controls.

php or asp.net give me good reaseon i need to know which is best for web development

There's no easy answer to that - it depends on your individual needs. If you want continuity with the .NET framework, or you code well in a language such as C# and would rather do that than learn another language, then ASP.NET is the way to go. However, Windows-based servers (for ASP.NET) are usually more expensive than Linux ones (for PHP) so it depends whether you want to spend more money for an ASP.NET server or not.
This article might help.

i think it depends on what kind of websites u r going to develop.
one reason to chose php, it's opensource u don't need to purchase license for it

Hi,
You may find this question quite absurd but I wonder how a project would be rebuild if a user performs some unexpected actions such as deleting the all files under bin and debug directory including dll files.
If I delete everything under bin directory and debug directory. How could I rebuild the whole project and lets say that I also deleted these files in recyclebin too. If I attempt to build or rebuild the project, I would get plenty of error messages and therefore none of essential files would be reproduced.
Rebuilding a project presumable be able to produce these essential files to create the structure of the project regardless of if there are errors or not in the project. Isn't that right?
Thanks.

It totally depends on the project
Many times i have deleted all the files from bin folder to make sure all dll will get refreshed and it works for me.
If you are referring any dll to ypur project and that dll was in bin folder then you will get n number of errors
Check your references of the application. All refered dll should not be in bin folder create a different folder.
Is it that you wanted ?
Let me know if you have any concerns ?
Thanks and Regards

Thank you for your respond. Here is what I did so far so good.
I removed webconfig file from the project and then reproduced it. I saw that all the errors in all the web pages' gone. The errors was pointing the first line in every page.
However I faced to another problem. The class files in back-end that are associated to pages were still pointing the errors. The reason was because when you crate a new aspx page, VS also creating class files for the page in back-end. However when the root information for the inheritance for the pages get messed up, all this class files are also getting messed up too. I couldn't file any solution for that how to fix it. Basically I decided to create a new project and then transfered all the contents of the pages. Now it is working but the way shouldn't be the solution to how to fix such error.
Thanks again.
Regards.

Why don't you use the Javascript substr function rather than incrementally adding the characters to the variable?
It takes the form:
string.substr(start, n);
where start is the starting character of the substring and n is the number of characters to return after this.
Change your code to:
var n="";
str=document.getElementById("attach").value;
m=str.lastIndexOf("\\");
m++;
n = str.substr(m, str.length-m);
document.getElementById("name").innerHTML = n;
alert(document.getElementById("name").innerHTML);
Tried in FF, Opera and IE and works in all.

The reason it doesn't work in IE is because it doesnt like you doing:
string[i]
to return a character; try something like:
var s = "hello";
alert(s[0]);
and try it in IE and FF and note that it returns undefined in IE. The JavaScript standards are slightly different in IE and Mozilla-based browsers so this is why.
If you wanted to return a character, the safe option would be:
var character = string.substr(i, 1);
where i is the character you want to return from string.
