           string search=txtbox_clotho.Text;
           if (txtbox_clotho.Text != "")
           {
               string[] licfiles = Directory.GetFiles(@"\\192.168.5.10\fbar\TOOLS\ProbingApps\ProbingSystem\Clotho_License", "*" + txtbox_clotho.Text + "*.lic", SearchOption.AllDirectories);
               foreach (string file in licfiles)
               {
                   lstbox_clotho.Items.Add(new ListItem(Path.GetFileName(file), file));
               }

            }
            
           }

You must be more specific than, "it's not working."

What is it doing wrong? Is there an error message? If yes, what's the message and on what line of code does it happen?

The difficult we do right away...
...the impossible takes slightly longer.

There is no error. It is not showing any messages..

Show the entire HTML document as it is passed to the client.

You do know that you can't just send that script snippet as the whole document, right?

Many problems! Let me dissect and show them to you:

First of all, why did you create a variable to hold the text, when you are again going to use the same object's Text property?

string search=txtbox_clotho.Text;
if (txtbox_clotho.Text != "")

Either remove the variable, or use the variable here. Tip: Remove the variable.

Secondly, if you have a look at the block where your alert-dialog's code is present?

else 
{
    Response.Write("<script>alert('For this Wafer ID Report is Not Generated');</script>");
}

How would you expected it execute when your condition is so wrong? "if (txtbox_clotho.Text != "")". The condition tells that the script would only be written, if the search term is empty; not invalid. Also, it doesn't work with the search result, it is applied to the search term (if I understand correctly).

Solution to this is, to re-write the code. Who wrote the code, so back? Where he was creating extra scopes (inside the if block), writing an entirely opposite condition and implement a very bad design, writing the script based on a Response.Write is always recommended not to be done. The code seriously needs some rewriting.

Explain the scenario, we can help you put some effort in it. Smile | :)

Only the language being used is C#, the framework that you are using is ASP.NET Web Forms. So, consider looking for an answer in ASP.NET Web Forms framework, not C#. In C# there are many ways to show a dialog,

// .NET
new MessageBox("Hello").Show();

// Windows Runtime
new MessageDialog("Hello").ShowAsync();

// etc

The one you are looking for is ASP.NET based, which is for sure, alert('hello'). The thing is that you are sending the alert box to the client, do not do this. Alerts must be shown once the page has been loaded, in case if there is an error. Do not show a popup as soon as the page loads.

Try this:

Send an ajax request to the web page, to find the files.
Send a response, if that response fails
- Show the alert box.

This way you will implement what you want, it would allow you to use plain-JavaScript to do this.

The choice will depend entirely on your requirements and business case (and funds). Most beginners will choose MySQL based on cost while others will choose SQL Server based on support resources.

Both will probably do the job you require.

I have a form. I added 2 usercontrol1 name: usercontrol1a and usercontrol1b, interval of usercontrol1a = 60ms, inter of usercontrol1b = 1000ms.
on usercontrola I draw something, on usercontrol1b I also draw something.
My problem is I want to know what happen while drawing usercontrolb come to the cycle draw of usercontrol1a.

Nothing untoward will happen as long as you aren't sharing state between the two user controls.

Why do you have tamper with the hardware?

There's a .NET location service.

Write a wrapper for it. If the service (or other resource) is not available, return your own values.

Sounds like you might be able to make use of a "location simulator"; based on your link.

The trick may be to keep the simulator running in "normal" mode.

You seem adverse to writing a device driver (probably the "normal" solution); I was suggesting the simulator as the seed for some other solution. My fault if I did not state that explicitly (sigh).

If you want to reject it outright, that's up to you. I never suggested it be used "as is".
