an event should be fired when clicking next page. Implement an eventhandler for the event, you can there alter the page of your datagrid. More info on MSDN.

Good luck.

I have created an event.

private void DataGrid1_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
DataGrid1.CurrentPageIndex = e.NewPageIndex;
DataGrid1.DataBind();
}
but when running the site, the event does not execute???

you 're using ASP.NET? not winforms?
In that case you should look into the lifecycle of the page. Try to bind the eventhandler sooner then the Load event (init eg.)

The lifecycle of asp.net pages is, in my opinion, not so easy to understand, but it is quite important.

good luck!

The easiest way is to create one base form, add the panel to that form. All the 5 forms should then inherit from the base form.

Make a user control (search panel) and make a MyForm class which inherits Form. Then add the user control to the MyForm.

When u need a Form with a search panel, just make add a new Form class and substitute the Form inheritance with MyForm.

public class SearchForm1 : MyForm
{

}

I'm in the high-fidelity first class traveling set.
And I think I need a Lear jet.

{
EventLog.CreateEventSource("CFirstLog","CFirstLog");
}
evLog = new EventLog("CFirstLog");
evLog.Source = "CFirstLog";
}

static void Main()
{
System.ServiceProcess.ServiceBase[] ServicesToRun;
ServicesToRun = new System.ServiceProcess.ServiceBase[] { new CFirst(),new CSecond()};

Preserving details of trial peiod in C#

Anonymous3-May-05 19:36

I am writing a C# program which will store the date of installation of the program on user machine along with the Disk Volume ID in an encrypted form, for trial period authentication. This information is generated by the program at the time of the first run. The problem is where to store this information on the user machine so that the user (including the administrator) cannot delete the same. Because if the user could find out where the information is stored (in a file or otherwise), he can simply delete the same and install the program again, which would re-initialize the date of installation. This will defeat the purpose.

So, some cross-check is required to be built so that if the user deletes this file or information, still on re-installation of the program, the cross-check can give the "true" information to the program about the installation date.

Any suggestions or ideas as to where this "cross-check" could be stored in a "safe" manner?

I would do it by installing a second copy of the same key somewhere else, so that if the first one is deleted, the second one can be checked. If you can encode this info into a file that you write to the hard drive, and call something.dll, or some other obsfucated name, that would be perfect.

No protection is fool proof, though.

When typing text into arich text box and I hit enter no new line is created. Is there a property to change to allow the user to create as many new lines as they would like?

thanks

Yes, there is a MultiLine property, which you have to assign True.

Happy Coding!!! Smile | :)

Thanks Ali. I have set that property to true and it is still the same.

Re: Rich text box

Please re-check your code.
The multiline property is the only one responsible for this effect and is set to true by default, so Ali's reply is absolutely correct.

Are you handling any key events yourself?

Same way you'd create a folder anywhere, the only issue is making sure you have the permission to do so, as the user you're logged in as within the site.

Treeview

With the standard treeview when a user right clicks a node to show a context menu the selected item does not change. I want to force this change. Is it possible and if so how?

Thanks for any help.

Re: Treeview

Christian Graus3-May-05 15:08

If there's an event you can catch for the right click, then a tree view has a method for finding the item under the mouse ( assuming it's not passed into the event handler ) and you can select it there.

You can subscribe to the MouseDown event and use the following piece of code.

if (e.Button == MouseButtons.Right)
{
    TreeNode node = treeView.GetNodeAt(e.X, e.Y);
    if (node != null)
       treeView.SelectedNode = node;
}

Parrallism in .NET

I came up with what I think Smile | :)

is a good idea for making multithreading programming easier in any .NET language. .NET 2.0 adds the capability to write anonymous functions, it would be nice if there was a "parallel" statement, that could simplify writing threadprocs

<br />
public void DoSomeParallelStuff() {<br />
  parallel<br />
  {<br />
    {<br />
       // do some network stuff<br />
         // this is an anonymous ThreadProc<br />
    }<br />
    {<br />
     // do some IO stuff<br />
    }<br />
    {<br />
   // do some DB stuff<br />
  }<br />
 }<br />
<br />
  // do other stuff, on caller thread<br />
}<br />

behind the scenes the compiler could create the anonymous functions, add them to the ThreadPool by calling ThreadPool.QueueUserWorkItem. in some cases it would be nice to automatically block the caller thread, maybe a sister statement "parallel-blocked"

<br />
parrallel-blocked {<br />
 {<br />
  // read from drive c:<br />
  StreamReader rd = new StreamReader("C:\test.txt");<br />
  ...<br />
 }<br />
 {<br />
  // read from drive d: (done in parallel)<br />
  StreamReader rd = new StreamReader("D:\test.txt");<br />
  ...<br />
 }<br />
}<br />
<br />
// thread blocks until all parallel anonymous functions complete<br />
Console.WriteLine("Tasks complete");<br />

I think this would make it much easier to write multithread capable code. I've actually added this feature to a compiler I'm working on and it works quite nicely.
