Delphi simple TCP server hangs. The form freezes but the server continues managing the clients.
- by NeoNMD
I'm using a form with an IdTCPServer on it managing strings from the client with a AThread.connection.readln/writeln system. The string handling works and that isn't the problem.
The thing is, the form with the server on it hangs and will not load, but it still managed all the clients connected to it so it IS running but it just doesn't work as a form.
I'll make a guess that its sitting on a readline or something... but I have NO idea how i can fix this at this moment in time.
Please help.
procedure TMonitorFrm.ServerExecute(AThread: TIdPeerThread);
procedure post(PostMessage:string);
begin
try
AThread.Connection.WriteLn(PostMessage);
except
showmessage('Cannot post');
end;
end;
var
ActClient : PClient;
sTemp,
CommBlock,
NewCommBlock,
ReceiverName,
sContent,
sSQL,
sCommand : String;
iCount2,
iCount : Integer;
sldb : TSQLiteDatabase;
sltb : TSQLiteTable;
begin
if not AThread.Terminated and AThread.Connection.Connected then
begin
CommBlock := AThread.Connection.ReadLn();
ActClient := PClient(AThread.Data);
ActClient.LastAction := Now;
sCommand := copy(CommBlock,0,pos(',',CommBlock)-1); {seperate command}
sContent := copy(CommBlock,pos(',',CommBlock)+1,length(CommBlock)-(pos(',',CommBlock)+1)); {seperate data block}
iCount:= 0 ;
if sCommand = 'Announce' then //SPECIAL
begin
{ Do stuff for this command...}
end
else if sCommand = 'CheckSect' then
{Etcetera...}
procedure TMonitorFrm.FormCreate(Sender: TObject);
var
sCompetitionID : string;
sldb : TSQLiteDatabase;
sltb : TSQLiteTable;
begin
Clients := TThreadList.Create;
Server.Active := True;
AreaPnlList := TComponentList.Create;
SectionPnlList := TComponentList.Create;
Repeat until InputQuery('Competition Select', 'Please type the ID of the competition', sCompetitionID);
iCompetitionID:=StrToInt(sCompetitionID);
OpenDatabase(slDb);
sltb:=slDb.GetTable('SELECT * FROM SectionTable WHERE CompetitionID='+sCompetitionID);
Frame31.CreateSections(sltb,Frame31);
sltb.Free;
CloseDatabase(slDb);
{
This section needs to check the SQLite databases for sections and list them in the display window and makes a drag n drop profile...
}
end;
