Hi guys,
I have a string, for example '1085462900'. I have to convert this string into a CTime / COleDateTime value. How can i do this?
I get this string from a oracle database.

What does that number represent?

This number represents Date and Time. The field on the database is from type int which contains this number.

I figured that much out. Is it the number of seconds since a particular date? Is it the BCD form of a date? Be specific.

Just for the common knowlege. This number is called UTC time and represents the number of seconds ellapsed since 1.1.1970, it is 0+ GMT time zone without day light saving addition

Ok, both CTime and ColeDateTime have constructors for handling such a value.

try
CTime ct = CTime((time_t)(_atoi((const char*)cs)));
and see if it matches the Oracle value

hiho@ll
i have some trouble with a browser helper object
using Internet Explorer is no problem, but if i close IE i get an Error message (somethings reading from space which it isn't allowed)
i traced a bit using MessageBox  and i found that the helper object destroys itself correctly using the WindowProc WM_Destroy event
then i get the error
and then DllCanUnloadNow is called successfully!
so what function is normally between the destroy windowproc and dllcanunloadnow?
thx@ll

Hi all
Wonder if you can help me, we are currently programing in MFC for our app which is dialog based - floating windows with 2 dialogs.
Our plans require more dialogs and a way to manage them on screen. What are are looking to do is create a "docking" architeture simlar to the toobars used in Photoshop (but at teh application top level).
Does anyone know of a component or toolkit that allows / helps build a dialog based UI with docking (allowing multiple dialogs to doc) / rollups etc ... or have any pointers or construction ideas?
All help very gratefully recived...

i used CWinThread.. the error message i'm getting is TrayDialog.obj : error LNK2001: unresolved external symbol "public: __thiscall CTrayDialog::CTrayDialog(void)" (??0CTrayDialog@@QAE@XZ).Please help..
CWinThread *pThread;
UINT Thread(LPVOID lp)
{
while(1)
{
AfxMessageBox("In Thread!");
Sleep(300);
}
return 0;
}
void CTrayDialog::TestThread()
{
CTrayDialog *obj;
obj=new CTrayDialog;
pThread=AfxBeginThread(Thread,obj);
}
thanks,

Hello,
Add the following lines of code to TrayDialog.cpp:
CTrayDialog::CTrayDialog() : CDialog(NULL, CTrayDialog::IDD)
{
}
What you are doing here is add the unresolved external symbol (the default contructor), but I think that you need an other solution: change the following code:
void CTrayDialog::TestThread()
{
CTrayDialog *obj;
obj=new CTrayDialog;
pThread=AfxBeginThread(Thread,obj);
}
to:
void CTrayDialog::TestThread()
{
CTrayDialog *obj;
obj=new CTrayDialog(this);
pThread=AfxBeginThread(Thread,obj);
}
Hope this helps.

Normally, when you use MFC and you create a dialog class, this class has a member called IDD. This is the dialog resource (how the windows looks and what controls are on it).
Since I don't know your classes, I don't know why you don't have them, but you can remove the line: : CDialog(...).

I must have switched the parameters. So the dialog resource comes second instead of first. If you are wondering what the other parameter is, it's the parent window of the dialog.

forget everything.... i'll come with a simpler example.. please wait.

Though it looks primitive.. please dont ignore..
see the class test with its data member "text" and function "disp()"
i wanna access it from the Thread1 and Thread2..
#include <afxwin.h>
#include<afxext.h>
#include<stdio.h>
char fValue[10];
CWinThread *pThread1,*pThread2;
UINT Thread1(LPVOID lp)
{
CClientDC cdc(AfxGetApp()->m_pMainWnd);
int j=250;
for(int i=1;i<=600;i++)
{
cdc.TextOut(i,j,"Thread1");
cdc.SetBkColor(0x0009999);
Sleep(6);
strcpy(fValue,"Thread1");
Text = fValue; ///// I WANT TO ACCESS THE DATA MEMBER "TEXT" FROM CLASS TEST//
cdc.TextOut(500,500,Text);
}
disp();/// HOW TO ACCESS MEMBER FUNCTION "DISP" FROM CLASS TEST//
return 0;
}
UINT Thread2(LPVOID lp)
{
CClientDC cdc(AfxGetApp()->m_pMainWnd);
cdc.SetBkColor(0x0990009);
int j=280;
for(int i=1;i<=600;i++)
{
cdc.TextOut(i,j,"Thread1");
Sleep(5);
strcpy(fValue,"Thread2");
Text = fValue;///// I WANT TO ACCESS THE DATA MEMBER "TEXT" FROM CLASS "TEST"//
cdc.TextOut(500,500,Text);
}
disp();/// HOW TO ACCESS MEMBER FUNCTION "DISP" FROM CLASS TEST//
return 0;
}
class test
{
public:
CString Text;
void disp()
{
AfxMessageBox(Text);
}
};
CMenu cm;
class MyWindow: public CFrameWnd , public test
{
public:
MyWindow()
{
Create(0,"Threads of MFC");
}
void q()
{
PostQuitMessage(0);
}
void Threads()
{
AfxMessageBox("Starting....");
}
DECLARE_MESSAGE_MAP()
};
BEGIN_MESSAGE_MAP(MyWindow,CFrameWnd)
END_MESSAGE_MAP()
class MyWin:public CWinApp
{
public :
BOOL InitInstance()
{
MyWindow *x;
x=new MyWindow;
m_pMainWnd=x;
pThread1=AfxBeginThread(Thread1,x);
pThread2=AfxBeginThread(Thread2,x);
x->ShowWindow(SW_SHOWMAXIMIZED);
return 1;
}
};
MyWin App;
thanks bob,

Hello,
Sorry for this late reply..
A couple of things:
<list> You pass a pointer x, that points to a MyWindow object to the thread as parameter, but you don't use it in either of your threads..
You call AfxGetApp() to get the value of m_pMainWnd
Your main app window is x
MyWindow derives from Test
Thinking about all these things don't ring a bell? Anyway, what you want to achieve can be done in at least the following 2 ways:
static_cast<MyWindow*>(AfxGetApp()->m_pMainWnd)->Text;
static_cast<MyWindow*>(lp)->Text;
Hope this helps

Can you post the header file of your class ? Please use formating tags (the code tag just above the emoticons).

cedric, my program is too complex.. even i'm worn out looking at the code..
can u post a simple program which wil explain it clearly?
should i declare the thread inside the class? just like we do for member functions?
i.e
class test
{
public
UINT Thread(LPVOID lp);
}
??
do we have any alternative for CWinThread?

paul the link u gave is ultimate.. thank u so much. really resourceful.i think i wont be disturbing u guys again.. everything's there 
The Thread Solution
It is almost always the case that you can use threads to do the job more easily. This is not without certain costs and hazards, but it ultimately is the better method.
Here's a solution to handling the invert-everything. Note that we have to move from the pure-C domain (which we interface to via a static method) to the MFC domain.
To the class (in this example, a CView-derived class), add the following declarations:
static UINT run(LPVOID p);
void run();
volatile BOOL running;
To start a thread, your handler does
void CMyView::doInvert()
{
running = TRUE;
AfxBeginThread(run, this);
}
UINT CMyView::run(LPVOID p)
{
CMyView * me = (CMyView *)p;
me->run();
return 0;
}
void CMyView::run()
{
for(int x=y = 0; running && y < image.height; y++)
for(int x = 0; running && x < image.width; x++)
changePixel(x, y);
running = FALSE;
}
The command to stop the thread is very simple:
void CMyView::OnStop()
{
running = FALSE;
}
That's all there is to it!
