read the file in binary mode, otherwise, you'll have to parser the string to recreate your own binary parsing (as C/C++ cannot handle binary directly).
be aware also that you cannot assign an integer (whatever type - char, short, long, int, __int64) with less of 8 bits...

From what I understood, the binary number is written litteraly (so you will have something like 00100101 in the file, not binary data).

Yes, the best way (IMO) is to read the number in a string and make a conversion function that returns an integer.
The conversion should be quite easy: start from the end of the string and add 1<<Pos to the result if there is a 1 at the position Pos (Pos is 0 at the end of the string)

There is already sush a function.
char szBuffer[80];
sprintf_s(szBuffer, 80, "1011");
int iBinValue = strtoul(szBuffer,
NULL,
2);
codito ergo sum

Yes, that's true ! I always forget about this one  . Why reinventing the wheel ? 
|

|
|

The only reason for reinventing the wheel is ...
when yours is rounder 
codito ergo sum
|
|
|
|
|
Yes but in general is rarely the case because this code has been tested by a lot of people before you.
Another reason is that you want to learn how the wheel turns

Possibly it's no rounder but lighter...

Hi
If u r using MFC, the AfxBeginthread function have a parameter to send a parameter to thread from calling function.
U can send the dialog's pointer to thread and by the dialog's pointer u can change the edit box value.
syntex:
AfxBeginThread(threadname, stacksize, void_parameter);
For exam,
void CMyDlg::OnBtnClick()
{
AfxBeginThread(MyThread, 0, this);
}
UINT MyThread(void *param)
{
CMyDlg *dlg= (CMyDlg )param;
.........
dlg->m_MyEdit.SetWindowText(text);
.........
return 0;
}
U can refer the sterday's message

Hi Parthiban
you are right but as i think, your code will work fine if CMyDlg is the main dialog of my application. But in my case, the dialog is not main dialog. It added that dialog from resoures. This dialog is a pop up dialog. In my case, that dialog is not initiating the thread. Thread is being initiated by main dialog.
Sorry i forgot to mention it before. Please help me.
Thank you.

Hi
Wat ever be the Dialog. if u can able to get the pointer of the dialog then u can change any values in the dialog.
Aqueel wrote: Thread is being initiated by main dialog.
Can u explain when u r initiating thread from main dialog? is any event from pop-up dialog?
|

In fact it is a timer. In main dialog, when user presses a button, a small dialog appears that counts time remaining and displays this time in an edit box.
I used your method. But how will i use UpdateData(false) here because to display changed value i will have to call this function.
Thank you.

I have to programatically simulate toolbar button click for all toolbar buttons present in a window. I cld successfully get the toolbar handle, and controlid of each toolbar button on the window so i use SendMessage with TB_PRESSBUTTON to simulate toolbar button click but button click does not happen and window attached to a toolbar button is not launched?
Currently am using EnumChildWindows() to get handle of the toolbar control attached to the window.
i use SendMessage(hwnd, TB_PRESSBUTTON, ibuttonid, TRUE) with TB_PRESSBUTTON having got the toolbar handle and each toolbar button controlid, to click each toolbar button but button click does not happen and the window attached to the toolbar button does not get launched.
with TB_PRESSBUTTON i see the effect of each button being greyed only but not clicked.
Am i missing something. Pls suggest how do i programatically simulate each toolbar button click to launch the window associated with resp toolbar button?
Waiting for a response.
Thanks.
Sincerely
Giftsana

Sorry, I was wrong about TB_PRESSBUTTON earlier. I saw the message and thought it was similar to the property sheet/wizard message that actually does simulate a button press.
I don't see anything in MSDN about simulating clicks. If you know the command IDs, you can just send the main window WM_COMMAND messages, which is what the toolbar would do anyway.

Hello Michael
Thanks for the reply.
I got it working using
SendMessage(hWnd,WM_COMMAND,IDC_QUOTE,MAKELPARAM(GetDlgItem(hWnd,IDC_QUOTE),BN_CLICKED));
Thanks again for the suggestion.

Hi freinds,
Why C++ constructor's does not have address ?
above question may be iterative..the answers I have got from internet/subordintaes are very generic like
1) They are special functions implemented by compiler
2) compiler may optimize constructors based on platform achitecture
3) Constructor call special memory routines so can not be exposed with address
4) constructor address is not needed at all, so why bother?
5)Any function which has return types must have address. and constrctor is not having return type and so the address.
I am not convinced by this generic statments. Experts can u please help me to have some precise/practical answers or with examples?
