Close window after MessageBox

[PawelR]

Hello group,
In my apps I connection to SQL database.
try
{
//connect to db
}
catch
{
MessageBox("Err or Connect. Close Apps?","Sql
Error",MessageB oxButtons.OKCan cel,MessageBoxI con.Error);

}
When db is connection error apps show messagebox with button OK and Cancel.
My question: How close this application after OK, and continuue apps after
Cancel?


catch
{
MessageBox("Err or Connect","Sql
Error",MessageB oxButtons.OK,Me ssageBoxIcon.Er ror);
Close();
}
Not work.


Thx PawelR

hi Pawel
use the dialogresult object

MessageBoxButto ns.OkCancel)
if (dlr == DialogResult.Ok )
{
close();
}
else
{
do...;
}

Re: Close window after MessageBox

PawelR,

I think that what you want is the static Quit method on the Application
class. It should shut down your application, and as a result, all of the
windows that go with it.

Hope this helps.

Re: Close window after MessageBox

this.Close();

should close the current thread(program) .
However, if you connect to the database as a part of a startup procedure
Close() will be ignored.

A possible solution to this is to throw a new exception after showing the
messagebox, and use a try/catch around Application.Run ();

You put the messagebox in an if statement and compare it with
DialogResult.OK to check if OK was clicked.

[STAThread]
static void Main()
{
try
{
Application.Run (new Form1());
}
catch
{
}
}

(...)

try
{
//connect to db
}
catch
{
if(MessageBox(" Error Connect. Close Apps?", "Sql Error",
MessageBoxButto ns.OKCancel,Mes sageBoxIcon.Err or) == DialogResult.OK )
{
throw new Exception();
}
}
