Nevermind, I figured it out!

ok,im trying to work with António Feijão,Remote Library
ContextRemoteExecute, to execute code into an remote process(on windows 2000 SP4).I would post the code but its rather long winded,but basically here is what im doing
1-open remote process
2-allocate memory with VirtualAllocateEx
3-write my code to allocated spot
4-suspend thread
5-get threads context registers
6-change the threads Eip to my allocated mem (0x00C7001C)
7-resume thread,and it crashes.
here is the disassembly of the remote process(location returned by VirtualAllocateEx and where my injected code lies)
00C6FFFF ?? ???
00C70000 55 push ebp
00C70001 8B EC mov ebp,esp
00C70003 83 EC 40 sub esp,40h
00C70006 53 push ebx
00C70007 56 push esi
00C70008 57 push edi
00C70009 B8 B8 0B 00 00 mov eax,0BB8h
00C7000E 50 push eax
00C7000F FF 15 A0 88 4F 00 call dword ptr ds:[4F88A0h]
00C70015 5F pop edi
00C70016 5E pop esi
00C70017 5B pop ebx
00C70018 8B E5 mov esp,ebp
00C7001A 5D pop ebp
00C7001B C3 ret
00C7001C E8 00 00 C7 00 call 018E0021 //here is the problem
00C70021 EB FE jmp 00C70021
00C70023 00 00 add byte ptr [eax],al
00C70025 00 00 add byte ptr [eax],al
now i dont understand why "E8 00 00 C7 00" is calling 018E0021 ?? shouldnt it "call 00C70000" like its suppose to?

I read on the web that you can add a COleDateTimeSpan to
a COleDateTime. How can I do this?
I want to put together a function that adds days to a current
date. Im really having a hard time with this. The algorithm
works for awhile, and then I start getting -1/-1/-1 for the
dates.
Please, any response any one can give me will be greatly
appreciated.
Sincerely,
Danielle Brina (an overworked graduate student)

Something like:
COleDateTime today = COleDateTime::GetCurrentTime();
COleDateTimeSpan oneDay(1, 0, 0, 0);
COleDateTime tomorrow = today + oneDay;

Is there any easy way to add a month, a half-year or a year to
the current date using COleDateTimeSpan?

Sure there is. Given that you know what month it is, just add the number of days in the current month and you'll get the same date in the next month. For example, today is June 14th. June has 30 days. Add 30 days to June 14th and we get July 14th. Make sense?

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

Thank you guys
it works fine

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.

what to do now bob? what's that IDD?

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.

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).
