Hello everybody,
I'm sure many of you have noticed that the doubleclick event of a datagrid object does not respond when clicking on a cell.
I googled and found that it's because the first click selects the textbox and the second click raises the Click event of that textbox.
now the obvious question is: how can I make the doubleclick event work? is there a way to make the datagrid control less complicated, or use a simple class of it's own instead of a textbox?

hi,
you can call the grid's double click event whithin the textbox's double click event.
that's all

Hello Hassan,
right I could point the two at the same procedure, but this will enforce a triple click to raise the double click event(1click =select +2clicks=dblckick) which is not what I want to achieve

Hi
I downloded motion detection in vedio from this link
http://www.codeproject.com/csharp/Motion_Detection.asp
But i want to adjust the motion detection sensitivity means if set sensitivity to large then it will detect the motion only in large scale,if it is set to small scale then it will detect small motion also.
Please give me solution related to that.
Otherwise give me an idea where can i adjust detection rate.
Please send me solution to mail2mamathak@yahoo.com
Thanks in advance.

"'"+ this.txtColumn1.Text + "'" + ","+
"'" + this.txtColumn2.Text + "'" + "," +
"'" + this.txtColumn3.Text + "'" + "," +
"'" + this.txtColumns4.Text + ")";
SqlConnection stringuu = new SqlConnection( "workstation id=mypc;packet size=4096;integrated security=SSPI;data source=mydatabase;persist security info=False;initial catalog=");
SqlDataAdapter daa = new SqlDataAdapter();
DataSet dss = new DataSet();

1. "'" is superfluous, you could just put them in with the other text.
2. None of your variable names are remotely meaningful, in your code or ( far worse ) in your database
3. You didn't tell us what the error message was
4. Why aren't you using stored procedures, if you can ?

Your first problem comes after your this.txtColumns4.Text. You forgot the ending "'".
Like I said, that is your first problem and actually your smallest. Your biggest problem is that you are open for Sql Injection errors. You should really be using paramterized queries to prevent this.

Just show here the code that gives the error.

this.picSnow.Image = ((System.Drawing.Image)(resources.GetObject("picMove.Image")));
//cboSnow
private void cboSnow_SelectedIndexChanged(object sender, System.EventArgs e)
{
switch (cboSnow.Text)
{
case "move" : picSnow.Image = picMove.Image;
MessageBox.Show ("move the snow");
break;
default: picSnow.Image = picSnow.Image;
break;
}//end switch
}//end cboSnow event
i paste a few code..the switch has 3 cases..move,throw and make..when i compile the event handler highlight the this.picSnow.Image ....
and before it's said there is no debug folder..and i should make one..how??

Sounds like you defined an event handler, then deleted the code, but the code in InitialiseComponent is still trying to hook up an event handler to the method that you deleted.
And you can't debug until your program compiles, a program that can't compile is one the compiler doesn't know how to turn into something that runs.

When I try to call Console.KeyAvailable I get the error measage:
Can not see if a key has been pressed when either application does not have a console or when console input has been redirected from a file. Try Console.In.Peek.
Why?
I haven't redirected it from a file or anyting.

No - no-one will do your homework for you, and they would not be helping you if they did.
Try to do it yourself, and then ask SPECIFIC questions. You'll find we're keen to help if people are willing to try it themselves.
Also, no-one will give you an email address, if you want to communicate, do it here. We get enough spam.

If you can't narrow down which bit of code is causing the error, to post it here, then you need to look at it closer yourself.

I *can* help you, I answer at least 20 questions a day. However, it's generally rude to appear on a forum, and ask people for email contact. The forum is here for you to contact us. If you have worked out where the problem is, by all means post the code so we can try and help.

Hi all,
I am intending to encrypt my C# application exe file by wrapping it in another exe file. Thereafter, at run-time, I want to decrypt this exe file and then run it. Now, my question is as under:
Is it possible to create the decrypted exe file ONLY IN MEMORY (i.e., without decrypting it in the form of a physical file on the disk) and then run it from there on the user machine? Secondly, will it be a stable process if I try to run the application in this manner ONLY FROM MEMORY.
Regards and thanks in advance.
