View 2 RepliesHow To Call A Codebehind Function And Return Data To The Client
Nov 5, 2010When I click on the following div:
<div id="Result">Click here for the time.</div>
I need the following codebehind function to run:
<WebMethod()> _
Public Shared Function GetDate() As String
Return DateTime.Now.ToString()
End Function
I need this to populate the inside of the div with the string returned by the GetDate() function. I think this should use code similar to this:
[Code]....
I've pulled this example from this site: [Code]....
However, I simply cannot get it to work. Nothing happens. This is just a regular asp.net web project. I haven't done any sort of Ajax-enabling business other than including script tags in my markup to reference jquery.
Here's what the firebug console tells me when I click on the div:
POST http://admin/Default.aspx GetDate 404 Not Found -18ms
Edit: Note: test.aspx/GetDate must match your aspx page name and function name!

View 4 RepliesSetting Image Width / Height In Codebehind?
Jul 27, 2010I am trying to set the width and height of images in a datalist in the codebehind.
The plan is to do something more complex than this based on the width/height, so setting width and height in the aspx file to 50% is not an option.
For some reason I always get 0 for width and height. Image1.ImageUrl is what i would expect though. Image is the System.Web.UI.Webcontrols.Image, not a System.Drawing.Image.

C# - Show And Position An Image Initialized In The Codebehind On Page?
Apr 30, 2010I have created a simple method to check if an image has been approved and finally returns it as an control. But how do i call and show it on the page? I've tried something like this in the aspx-file:
<% SendImage("DKBygMiniLogo.gif", "True"); %>
Here is the simple method:
protected Image SendImage(object Image, object Approved)
{
bool approved = Convert.ToBoolean(Approved);
Image img = new Image();
if (approved)
{
img.ImageUrl = "~/images/Ads/" + Image.ToString();
img.Visible = true;
}
else
{
img.ImageUrl = "~/images/Ads/" + Image.ToString();
img.Visible = false;
}
return img;
}
How do I actually show the image?
Return Image From .aspx Link?

C# - Can Call An Aspx Page And Have It Return An Image
Oct 6, 2010I have two files. The first file is called FinalImage.aspx and here is the code for that page:
<html>
<body>
<img src="newpage.aspx" />
</body>
</html>
newpage.aspx has the following code, based on Jason's sample in the comments below:
<%@ Page Language="C#" %>
<script runat="server" language="c#">
protected void Page_Load(object sender, EventArgs e)
{
Response.ContentType = "image/png";
byte[] data = System.IO.File.ReadAllBytes("http://mystatus.skype.com/smallclassic/eric-greenberg");
Response.OutputStream.Write(data, 0, data.Length);
Response.OutputStream.Flush();
Response.End();
}
</script>
If I call FinalImage.aspx I see a broken image.
If I call newpage.aspx directly, I get a "URI Formats are not supported error"
I think its close, though. this solution is needed to get around the fact that skype does not have an https option for its skype buttons which tell the status of the skype user. Creating this proxy page will allow this to work without causing a 'mixed' security alert in the browser.
SQL Server :: DAL Doesn't Return The Return Value Of Stored Procedure?
Nov 8, 2010I have an update function in my data layer which is defined as:
public int UpdateRBTable(parameters ...) This calls a SQL Server Stored Procedure to perform an update function on the database.
The process does its job for updating the table. However, the stored procedure has a return value (which indicates how many rows were updated), but this return value is not returned to the application. The application always shows that a zero was returned from the stored procedure.
