1- If you want to resize the image just for display then you can set the width and height of the image as required.
2- If you want it be interactive, so that client can resize the image then I will prefer some jquery plugin to do this task. Check this out http://plugins.jquery.com/taxonomy/term/2532[^]
3- If you want to do this at server side then using the GDI+ you can resize the image. Check this Resizing a Photographic image with GDI+ for .NET[^]

I need to resize and want to save in disc so pixel quality will be maintained.

You get the best out of others when you give the best of yourself.

Then explore the 3rd option, you will find some example in the article which scales the image by fixed size of percentage.

This Function Can help you! 
Public Function ResizePicture(ByVal sourceImage As Bitmap, ByVal newSize As Size) As Bitmap
Dim Result_image As New Bitmap(sourceImage, newSize.Width, newSize.Height)
Dim Gr As Graphics
Gr = Graphics.FromImage(Result_image)
Gr.DrawImage(Result_image, 0, 0, newSize.Width, newSize.Height)
Gr.Save()
Return Result_image
End Function
Then you can save the output of this Function By using ResizePicture(MyBitmap, New Size(100, 100)).Save(MapPath("/") & "/Images/MyImage.png", Imaging.ImageFormat.Png)
Note: These codes are in VB.NET Language, but you can simply convert it to C# or any .NET language

just 2 questions:
1) is there such a thing as a default httphandler? for example, the handler that is invoked when the extension of a requested resource is not assigned to a handler within the .config file?
2) a related question is a handler that is invoked for any resourcetype requested?

Yes there is. DefaultHttpHandler renders every request when no custom HttpHandler is configured.
See
http://msdn.microsoft.com/en-us/library/system.web.defaulthttphandler.aspx
Yes for every request to a resource too there is an httphandler. WebResource.axd is configured in Web.Config which requests resource embedded in your dll.

“Unable to establish secure connection with the server” seems to be due to Authorization failure.
You are using forms authentication, and account on which the application is running is not having access to the Active Directory. Try doing one of the two things.
1- Change the authentication mode to Windows and set the < Identity Impersonate="true" > in the configuration file.
2- If its not possible to change the authentication mode then try to impersonate a AD user dynamically before establishing the connection to ADSI and undo the impersonation once you are done.

Are there any other information that you can gather, other than the "Unable to establish secure connection with the server."? Can you check at runtime if you code is actually connecting to sdmcet.sdmcet.cse and negotiating with authentication? This error can be due to the fact that sdmcet.sdmcet.cse cannot be found. You may opt to use IP address instead of sdmcet.sdmcet.cse. Also, "secure" connection usually means your URI should include S (LDAPS://) instead of plain LDAP://.

I have a table row tag with three td blocks, and below a tr with two td blocks.
On the second tr, I want the td blocks to run all the way across the screen, but it stops level with the end of the end of the second td block in the preceeding tr.
?
Am I being dim?

Hy,
i have to open a page and remove its tool bar at runtime.is there any way i can do it while using response.redirect as i cannot ue window.open
|
|
|
|
|
You can always set the visibility of a control, either from the code-behind or via javascript. Response.Redirect has nothing to do with it.

you need to use JavaScript and it will only work for a popup window. - else you cant do it "Security Issues".
It is Good to be Important but!

It is not possible to programmatically hide the menubar or toolbar on a window that is already open. I found similar JS from the net but it is for Netscape:
function showmenu()
{
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
window.menubar.visible=true;
window.directories.visible=true;
window.statusbar.visible=true;
...
and I do not know if it works. (who's using Netscape anyway? Official support for Netscape ended on March 1st, 2008.)

I am using the asp.net mvc framework and like it so far, however there are times that I need to use a code behind page. mainly for my gridview events and such. MVC does not use or recommend using code behind pages. So my question is, how would I put the events for my gridview, or any code that is in my code behine, in my usercontrol and aspx pages?
Would it be as simple as this:
UserControl sample:
<br />
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ai_dcs_isets.Models.dcs_users>" ><br><br />
<%@ Register Src="PopUpBox.ascx" TagName="PopUpBox" TagPrefix="uc1" ><Br><br />
<uc1:PopUpBox ID="PopUpBox" runat="server" ShowCloseButton="true" /><br><br />
<br />
<script language="C#" runat="server"><br><br />
void page_load(Object sender, EventArgs args)<br><br />
{<br />
<br />
<br />
}<br />
<br />
</script><br />
if so, what is going to keep these events in order if my user control is apart of a page that has it's own page_load or other events? Would my gridview events be a mere copy and paste from code behind to the script area?
Sorry if this is a basic question, web development has never really been my main development.
Thanks for the help.

MVC does not include code-behind for a good reason; asking to use it violates the concepts and principles of the pattern.
What events are you trying to use?

I agree, which is why I need to put what code I was going to use in code behind, in my usercontrol and aspx pages.
The code right now that I need to use:
<br />
void Page_Load(object sender, EventArgs e)<br />
{<br />
<br />
}<br />
<br />
void GridView1_SelectedIndexChanged(object sender, EventArgs e)<br />
{<br />
<br />
}<br />
<br />
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)<br />
{<br />
<br />
}<br />
<br />
And possibly RowCreated event.<br />
Right now it is just this. Some of my code I could move to the Controller and also most can be handled in the Model itself, but events like this I am not sure what to do with.
Thanks for the time.
