The current time is showing 03.00pm

but after 1 minute the current time should be 03.01pm

i cant compare

help me

Since it is (by OP's admission) a buggy algorithm, hence yes, I can implement it. Poke tongue | ;-P

Hi..
here code.

CurrTime = COleDateTime::GetCurrentTime();
CurTime.Format("%02d:%02d:%02d",CurrTime.GetHour(),CurrTime.GetMinute(),CurrTime.GetSecond());
COleDateTimeSpan ts(0,0,cDuration,0);
EndTime = StartTime + ts;
StTime.Format("%02d:%02d:%02d",EndTime.GetHour(),EndTime.GetMinute(),EndTime.GetSecond());

if(linfo->bServerConnected==false)

What a mess!
(1) use <pre> tags to surround code snippets.
(2) You should never use ExitThread.
(3) What is the purpose of _endthread()
(4) What is the purpose of the following lines?

CurTime.Format("%02d:%02d:%02d",CurrTime.GetHour(),CurrTime.GetMinute(),CurrTime.GetSecond());
StTime.Format("%02d:%02d:%02d",EndTime.GetHour(),EndTime.GetMinute(),EndTime.GetSecond());

(BTW how are CurTime, StTime declared?)
(5) A far a I can see CurTime is never updated.
(6) Probably an equality test on times is not appropriate (maybe better >=).

IMHO we're a bit far from the target.

That means it is updated inside the thread routine. Could you please post that code (maybe the variable declaration will be helpful too)?

Well, code needs a bit refactoring I suppose. We could help.

Dear Friends,

i m working on an VC++ application and using oracle as a backend. Through my application i m writing some data to Oracle database. After certain number of iterations i m getting Commit error (8197). Can anybody help me with this? What might be the reason for the same.

have you googled for that error number ?

also, have you checked Oracle documentation ?

because this is a VC++ forum, we are not Oracle experts.

How to invoke application/service on another computer

Hello experts,

I have a project that drive me crazy. I would appreciate if any bony can help/guide me
I have 2 computers both running XP Pro SP2 called PC-A and PC-B.
PC-A is an embedded computer. It has an application to do some specific task. Right now, I have to run it manually and save the results for my other tasks. I do have source for this application.

I have another application on computer PC-B. This application is relying on the results from PC-A which right now I have to enter manually.
These 2 computers are connected via ethernet cable. I do have source for this application as well

I would like to modify the application on PC-B to tell PC-A to run its application and return results to PC-B so PC-B can perform its task automatically.

I don't know where to start.
Please help me out with some direction/links. Example would be perfect

Thanks in advance

install PsService[^] on the calling machine, then use it like this :

psservice \\192.168.0.15 -u the_user -p the_pwd start the_service

which data ?

have you tested it ?

here, we use it in all our servers architecture, so, it works well !

if you want more detail about it, maybe you should have a look at the API used by its author :

How it Works
PsService uses the Service Control Manager APIs that are documented in the Platform SDK.

Dialog application

When my MFC application is run, it invokes a dialog. Though I have removed the OK and the cancel button from the dialog my dialog can be dismissed by pressing the esc key. is there a way to prevent the default behaviour of the escape key to be overwritten.
Also i like to dismiss the dialog by posting a message after some time. how to I post a destroy message to the dialog.

Hmm, have forgotten how to do they escape key bit, there's a function in one of the MFC classes your Dialog is deriving from that turns Esc into a WM_CLOSE, you need to override that or prevent it being called, a PreTranslateMessage override might be able to do it.
When it comes to closing the Dialog your best bet is probably to use a timer, MFCs timers are fine and when it goes off use PostMessage to have the dialog send itself a WM_CLOSE. Don't use SendMessage or things may go horribly wrong when you return to run code in a deleted dialog. Smile | :)

If the dialog closing is conditional then set your timer to a short period, like a 10/th of a second and check the condition. If it's not met just set the timer again.

Override PreTranslateMessage, for instance

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg)
{
  if ( pMsg->message == WM_KEYDOWN )
  {
    if (pMsg->wParam == VK_ESCAPE)
    {
      return TRUE;
    }
  }
  return CDialog::PreTranslateMessage(pMsg);
}

BTW probably you'll have also to handle RETURN key.
