Hello,

I need to do following. If object was not initialized then assign variable to it like code below.
Right now it throws an error becouse MyCert is not initialized when compared to null. How do I do what I need to do?



X509ChainElement MyCert;
foreach (X509ChainElement cert in chain.ChainElements)
{
if ( MyCert == null)
{
MyCert = (X509ChainElement) cert;
continue;
}
else
{
.....;
}
}

Hello,

I am loading a file within my app and the way I am refering to it is something like that:


this.richTextBox1.LoadFile("c:\\tmp\\Document.rtf");

However if I want to deploy the application on some other machine, obviously the file will not be there. So, if I want to include the file in my application how do I refer to the file then?

Thank you.

try 
{
  this.richTextBox1.LoadFile("c:\\tmp\\Document.rtf");  //of course point to where you think it is
}
catch
{
  OpenFileDialog ofd = new OpenFileDialog();
  ofd.Title = "Please locate Document.rtf";  //or whatever title you want
  ofd.Filter = "RTF File|*.rft";
  ofd.ShowDialog();

  if ( ofd.FileName != "" ) { this.richTextBox1.LoadFile( ofd.FileName ); }
  else { // do something to handle the error }
}

the application starts with about 6mb memory.
when the last messagebox is displayed, everything should be disposed and the memory should return nearly to 6mb. but it doesn't.

has anyone any idea how to get the GC to collect this unused (but reserved?) memory?
i have to engineer a little application which will run on a terminalserver for each user. (50users x 10mb unneccessary memory is not very good...)

My only idea is to send another message to the form when the label recives it, but this seems a little long winded.
