HI,
Thanks In Advance.

I am creating a Dialog Based Application for getting the current Time and displaying the time in the Edit Box. I got it using COleDateTime class. But i want to get the seconds Edit Box to be Updated continuously.I mean the application to be in running state.

void CTimeDlg::OnTime()
{
COleDateTime d,t;
d = t.GetCurrentTime();
m_hour = d.GetHour();
m_min = d.GetMinute();
m_sec = d.GetSecond();
UpdateData(FALSE);

// I tried the below line but in vain.
// I realized that OnTime() method is BN_CLICKED event
OnTime();
}

Here i want to call the OnTime() method repeatedly. Is it possible to do so?

Look up the SetTimer API - It should do the trick.

I think you want to display the current time in a EditBox

Use SetTimer to Set a Timer preferable in OnInitDialog

SetTimer(2500,1000,NULL);

this is fire WM_TIMER every second

Use ClassWizard to handle WM_TIMER message

.....::OnTimer(UINT nIDEvent)<br />
{<br />
     //Calculate the current time<br />
     //Use SetWindowText instead of UpdateData for Performance reasons<br />
<br />
     CDialog::OnTimer(nIdEvent);<br />
}

This is probably not the best way (cause of the delays) but will work

Hope it helps

Dont ask plain when you talk about simulators. it has a *wide* meaning. In what context you wanna know about simulator?? a Mobile device??

I dont even know that. When i start my system two simulators called Clinical and NonClinical are getting activated. (I guessed that)With that only I am able to get data for Clinical and Non clinical data.

Question label in caption bar?

Hello snprani,

A simple meaning of simulator is virtual world.

In simulater you can create a real environment effect virtualy.

It is use for testing of device, Training & many more places.

Hi,
under VC6 in a SDI project i want to have the question label (for context help) in the caption bar (in neighbourhood to min/max/close-Button) *but* in the main program window (not in normal dialog boxes .. that's easy). I tried much code with ModifyStyleEx() but nothing worked. Is it possible without writing complete new classes? Has anyone a sugguestion for a simple solution???
Thanx!!!

The WS_EX_CONTEXTHELP extended window style is not compatible with the WS_MINIMIZEBOX or WS_MAXIMIZEBOX styles. The context help icon isn't displayed on the caption as long as one or both of the minimize or maximize boxes is displayed. The same thing happens with dialog boxes using the DS_CONTEXTHELP and the WS_MINIMIZEBOX or WS_MAXIMIZEBOX styles.

Note that the window must have the WS_SYSMENU style.

Make sure the windows has the WS_EX_CONTEXTHELP style. This is an extended style. If you use ModifyStyleEx you may need to add code as follows to make the change take effect:

SetWindowPos(hWnd, NULL, 0, 0, 0, 0, SWP_NOZORDER|SWP_NOMOVE|SWP_NOSIZE|SWP_FRAMECHANGED);

Inside OnCreate

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
  ....
  ModifyStyle(WS_MINIMIZEBOX|WS_MAXIMIZEBOX, WS_SYSMENU);
  ModifyStyleEx(0,WS_EX_CONTEXTHELP, 0);  
  ...

I'd like to know how I can programmatically play an old Fast Tracker 2 XM module? Thus, where can I find a set of source code that shows how to play these files without DLLs or LIBs...

Thanks for the help.
