By building a permissions system, and by dynamically building your menu, or having set menus for different classes of user.

Your pages need to reject users that don't have permission, in case the page is entered manually or bookmarked.

Your .NET controls are given names that are different to the names you give them on the server side. So you need to add script like this:

var myControlId = '<%=myControl.ClientID%>';

Then you can write code that uses document.getElementById with the myControlId variable, and work from there.

If you are using asp.net 2.0 you can use its fileupload control.

hi i am currently trying to use a gridview control to view data from the database.
however one of the field is an image.

the format i need to display is: id(labelbox),image(imagebox)

but in the database my data is saved as id(text),pic(text,image name only like asd.jpg)
however my image is all in the image folder...

meaning i am trying to configure the imagebox in the gridview control to add the "image/" in front of the now image name.

<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("Pic") %>' Height="100px" Width="100px" />

this is what i got after changing the coulum to a template

now the imageurl is like imageurl="asd.jpg" how ever i need it to be imageurl="image/asd.jpg"
is there anyway to do this without on the below code?

<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("Pic") %>' Height="100px" Width="100px" />

you need to do this in the eval statement (from memory):

ImageUrl='<%# "image/" + Eval("Pic") %>'

Have a look in IIS to make sure it's got an ASP.NET tab in the properties for the default site. If you've run regiis, I'd have to wonder if IIS is even running.

No, it's not possible to run ASP.NET if ASP.NET is not registered, and .NET installed.

System.Drawing.Color doesn't implement IEnumarable

You will have to do something like this.

System.Drawing.Color c;
string[] colors = Enum.GetNames(typeof(System.Drawing.KnownColor));
foreach (string color in colors)
{
    c = System.Drawing.Color.FromName(color);
}

Hi everybody,

I was developing an Windows Application that uses a USB device. To communicate with this device I needed a Handle to my application. That was fairly simple, I just used this.Handle in the Windows Form!

Now I want to build a web service that connects to the same USB device. Therefore, I need a Handle to my web service, but there is no such thing as this.Handle in HttpApplication! There must be a way of getting it, but I can't find it! Can anybody please help me?

Thanks!

You should probably double check the value that is in URL when you pass it to Create and make sure that it's the proper value that you think. Also you should make sure that there isn't a firewall that might be blocking the server.

This Exception is rarely encountered, usually when sync is initiated with either 'Upload, Synchronize with Outlook precedence or Synchronize with Google precedence' operations, for certain recurring events.

This exception is thrown by the Google server when it is not successful in updating or adding certain recurring events in the Google calendar. This intermittent issue has been confirmed by Google and the Google team is working to resolve it.

Being intermittent, mostly this exception disappears when sync is initiated multiple times. Therefore, all the SyncMyCal users who are getting this exception are requested to initiate sync multiple times and see if sync is successful.

Getting changes to the data from a repeater control

Senseicads30-May-07 3:03

I have a repeater control that is populated with values from a database every minute. This was done using an AJAX timer and update panel. This all works. What I would like to do is when a new row is added to the repeater control(presumably from someone adding a new row on a copy of the app elsewhere) and it is displayed in the repeater. To find someway of highlighting that row to show it is new.

Breaking it down I need to find someway of recognising that the data in the repeater has been changed, then I need a way of highlighting it. Can anyone help??

I was thinking of possibly attempting to populate a dataset from the data contained in the repeater, then databinding the repeater then reloading the dataset with the changes and calling get changes. But I dunno what I am doing and I can’t get this to work and the only way I know how to use a dataset is with a datadapter which I don’t think will work? I have never used datasets before and I can’t really find much help for it on the msdn. If anyone can tell me how to do this it would be most appreciated.

Cheers

Ian

Assuming you have control over the database, I'd be tempted to look at adding a "LastUpdated" datetime field to the database table, and then using the OnItemDataBound event to check for this during binding, and highlighting rows that have been updated in the past X mins/hours/whatewver....
