Dunno, maybe remove the newName) and stick a ) just before the ; ?

//My.Computer.FileSystem.RenameFile((dest), newName:=sheet.Cells(row, 14).value & "_" & sheet.Cells(row, 15).value)
My.Computer.FileSystem.RenameFile((dest), newName) sheet.Cells(row, 1).value;

Your second line isn't the same as the first one. The reason is down to the fact that in the VB line, it's attempting to put sheet.Cells(row,1).value into the optional parameter newName. In your version, you don't do that - so the statement ends after the call to RenameFile.

Using a parameter name followed by a := means that you create that variable on the fly and assign the value to it. Just think of two statements:

string newName = sheet.Cells(row, 14).value + "_" + sheet.Cells(row, 15).value);
My.Computer.FileSystem.RenameFile(dest, newName);

a) don't use bold: it's shouting!
b) what have you already tried for yourself?
c) one question at a time.

To add to that;

It's a lousy subject line; doesn't tell us anything about your problem.
You're not urgent to me. Why would it, just because it's included in the subject?
Don't use text-speak. We're not sms-ing, and you don't pay by the character.

Depends. Read the documentation that comes with the SDK. Yes, it's called "research".

By having each known fingerprint known in a table, and executing a query to verify it's authenticity.

How to prevent multiple button clicks

I have a c# .net project that has a button on the form. When the button is clicked twice, bad things happen. How do I disable the button?

I've tried disabling my button as follows but it doesn't work.

btn_Program.Enabled = false;

I've searched for this online, but every solution seems to reference asp.net. I don't think I have that, do I? I'm fairly new to c# and visual studio, so I may have it and not know it.

I liked the following discussion, but again, it refers to asp.net.
http://stackoverflow.com/questions/8473261/how-to-disable-a-button-after-1st-click[^]

The example I liked had the following code in it, but when I add it to my form class, it gets a compilation problem for ClientScript and Attributes:

static void DisableButtonDuringPostback(Page page, Button control)
{
    StringBuilder sb = new StringBuilder();
    sb.Append("this.disabled = true;");
    sb.Append(page.ClientScript.GetPostBackEventReference(control, control.ID.ToString()));
    sb.Append(";");

    control.Attributes.Add("onclick", sb.ToString());

}

It said to add the following to Page_Load

DisableButtonDuringPostback(this.Page, Button3);

Compilation problems:
1. 'System.Windows.Forms.Button' does not contain a definition for id and no extension method id accepting a first argument of type 'System.Windows.Forms.Button' could be found (are you missing a using directive or an assembly reference?)

2. System.Windows.Forms.Button does not contain a definition for Attributes and no extension method Attributes accepting a first argument of type System.Windows.Forms.Button could be found (are you missing a using directive or an assembly reference?)

Any help would be very much appreciated.

Add a timestamp; if it comes in again, compare the current time to the datestamp you saved earlier. If it is <2 seconds, ignore and cancel execution of the request.

I ran into some issues with the other idea and now I'm using your idea. Works great! Instead of using the timestamp, though, I set a boolean flag, and reset it when I'm ready for a second click.

<quote>

btn_Program.Enabled = false;

Are you sure that btn_Program is the correct button to disable?

Since you aren't sure to have started an ASP.NET project, I will assume you have a Windows Forms project instead. That would mean that you have a button click event handling routine somewhere that looks similar to this:

void btn_Program_Click(object sender, EventArgs e)
{
   // ... your code here ...
}

To definitely disable the correct button, you can use the sender parameter:

void btn_Program_Click(object sender, EventArgs e)
{
   // Disable the button whose Click event started this method
   System.Windows.Forms.Button methodStartingControl = sender as System.Windows.Forms.Button;
   if(methodStartingControl != null)
   {
       methodStartingControl.Enabled = false;
   }

   // ... your code here ...

   // Re-enable the previously-disabled button
   if(methodStartingControl != null)
   {
       methodStartingControl.Enabled = true;
   }
}

Ciao,

luker
