I dont know what you mean?
Sorry i'm a little bit new with visual c++.
is this what are you talking about?
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CPractica6Dlg)
DDX_Text(pDX, IDC_NUMA, m_numA);
DDX_Text(pDX, IDC_NUMB, m_numB);
DDX_Text(pDX, IDC_RESUL, m_result);
//}}AFX_DATA_MAP

Situation out of control. Cease Fire!. But check the values of m_numA, m_numB & m_result by displaying in a message box jsut before the multiplication and just after the multiplication.

Values
m_a=1
m_b=2
pick radiobuton +
pick solution
m_result=3
then I change values
m_a=3
m_b=4
radiobuton + activated
pick solution
m_result=3 and m_a and m_b changed to
m_a=1
m_b=2
but if i do this it works
m_a=3
m_b=4
radiobuton + activated but i pick it another time
pick solution
m_result=7

This is the problem with UpdateData(). If not used 100% correctly, it causes more problems than it solves.

I discover that if i push twice in the radio button it works. i thinks that is because when you change the radio button it dont reload the new values so if you pick twice in the same radio button satrt to work.
Any ideas to solve this???

How you r reading the values of the radio button, and which event you have trapped, is it double click.

Is it possible to create an Event within a Service (running under LocalSystem), and then signal that same event from another process (i.e. a normal process)?
I tried setting the security descriptor for the event to enable 'all access' to 'everyone', but it doesn't seem to work - GetLastError returns '5: access is denied'.
Is it the case that the event object is exclusively reserved for the service?
|
|
|
|
|
1. Yes, you can.
2. Perhaps you created the security data incorrectly.
3. No - we do this all the time.
|
|
|
|
|
|
Create a named event. then any process can open that event and signal or detect it.

Of course. The easiest way is to use SetWindowText(). But since you have a hangup with it, you'll need to use ReplaceSel(). To keep the insertion point at the "end" of the control, use SetSel().

Hi,
I am using the below two line to execute an crystal report file from VC++. I can't able to see my report(Report is not displayed). i also specified the destination to window in the crystal control properties.
m_CrystalReport.SetWindowTitle("Trucks Loaded Report");
m_CrystalReport.PrintReport();
How can it invoked in other ways.. Urgent
Give me a touch... Regards,

how to change background color of CRichEditCtrl?
includeh10
|
|
|
|
|

For other controls, the correct way would be with OnCtlColor(). However, I do not see a CTLCOLOR_xxx value for rich-edit controls.

there are 3 std* handles: stdin,stdout,stderr;
we can use GetStdHandle() with STD_INPUT_HANDLE,STD_OUTPUT_HANDLE,STD_ERROR_HANDLE as param to get 3 handles also.
what are differences between the 2 group handles?
i.e. between stdin and GetStdHandle(STD_INPUT_HANDLE)?
in my dos program, GetStdHandle(*)s work well but stdin, stdout and stderr do not work. do u know why?
thx

Which indicates that you are possibly using them incorrectly. Please post the code snippet that is not working.

Hi,
this dos app is an interface between other 2 apps, it is very short, here is all code:
1.if relacing GetStdHandle() with std*, the program is not working.
2. it works on win98, but doesn't work on XP, what is wrong?

This is one of those situations where stdin/stdout and a HANDLE type cannot be interchanged. Remember that stdin/stdout are derived from the _iobuf structure, and the handles returned from GetStdHandle() are true handles (void* types).
