Handling Errors when SimConnect is not Present

[scruffyduck]

I am finding that if Simconnect is not present or the wrong version there is no way to catch the error. A program like ADE should work even when FSX is not present although without the Simconnect functions. However I am finding that the crash occurs very early and I can't put any error trapping round it at the moment.

Using C#.

Thanks in advance for any pointers.

I tested in the setup package.

Using inno setup the script is something like this:

function InitializeSetup(): Boolean;
var
  ErrorCode: Integer;
  NetFrameWorkInstalled : Boolean;
  SimConnectInstalled : Boolean;
  Result1 : Boolean;
  sRet: string;
begin

  NetFrameWorkInstalled := RegKeyExists(HKLM,'SOFTWARE\Microsoft\.NETFramework\policy\v2.0');
  if NetFrameWorkInstalled =true then
  begin
    Result := true;
  end
  else
  begin
    Result1 := MsgBox('This setup requires the .NET 2.0 Framework. Please download and install the .NET Framework and run this setup again. Do you want to download the framework now?',
      mbConfirmation, MB_YESNO) = idYes;
    Result:=false;
    if Result1 =true then
    begin
      ShellExec('open', 'http://www.microsoft.com/downloads/details.aspx?familyid=0856EACB-4362-4B0D-8EDD-AAB15C5E04F5&displaylang=en','','',SW_SHOWNORMAL,ewNoWait,ErrorCode);
    end;
    exit;
  end;

  SimConnectInstalled := RegValueExists(HKCR,'Installer\Assemblies\Global','Microsoft.FlightSimulator.SimConnect,publicKeyToken="31BF3856AD364E35",version="10.0.61242.0",processorArchitecture="x86",culture="neutral"');
  if SimConnectInstalled =true then
  begin
    Result := true;
  end
  else
  begin
      MsgBox('This setup requires SP1 Simconnect . Please Install it',mbInformation, MB_OK);
      Result:=false;
  end;

BTW inno setup is free and IMO the best package available. You can't complain about the price

Hi Jose

Thanks - I am not using an installer at the moment - I guess I need to

Hi Jon.

private void button_Connect_Click(object sender, EventArgs e)
{
if (my_simconnect == null)
{
try
{
my_simconnect = new Microsoft.FlightSimulator.SimConnect.SimConnect("Managed Data Request", base.Handle, 0x402, null, 0);
setButtons(false, true);
initDataRequest();
timer1.Enabled = true;
}
catch (COMException)
{
label_status.Text = "Unable to connect to FSX";
}
}
else
{
label_status.Text = "Error - try again";
closeConnection();
setButtons(true, false);
timer1.Enabled = false;
}
}

This gives TCalcX a way to handle the error.
