On the CBitmapButton, of course

I know what you are trying to say, that the focus is stealing by CMainFrame, but I must say that CBitmapButton react on "SPACE" key, so that is the prove that the button had th focus ...

Actually, I was not trying to say anything, merely asking the obvious question. I had a good root through the documentation for this control and cannot find anything in MSDN that explains what is supposed to happen. I know that in a normal dialog it will work this way, but I don't have MFC so cannot make a sample to test what you are trying to do.

Ok, I understand. Thank you for your concern.

hi all,
I am get window text like this in my function it works fine for multibyte data but fails in case of Unicode data.
HWND hWnd;
char string [256]={_T('\0')};
::SendMessage(hWnd, WM_GETTEXT, 255, (LPARAM)string);
and
TCHAR szBuffer[MAX_PATH] = {_T('\0')};
SendMessage(hWnd, WM_GETTEXT, sizeof(szBuffer) / sizeof(TCHAR), (LPARAM)szBuffer);
please help me to get the Unicode data.
thank in advance.

I have used the same code as you have above to receive the Unicode text from a window. Are you sure you set the project options to select a UNICODE build?

Hi all,
I am getting a weird stack overflow after calling the MFC function SetLocalTime. There is no code to step into and no call stack. I am using Visual Studio 2008 on Windows CE.
Here is my code:
void OnBnClickedButtonSet()
{
SYSTEMTIME time, new_time;
GetLocalTime(&time);
//get the date info
time.wYear = static_cast<WORD>(i_year);
time.wMonth = static_cast<WORD>(i_month);
time.wDay = static_cast<WORD>(i_day);
//get the time info
DWORD ret = m_Time.GetTime(&new_time);
if (ret == GDT_VALID)
{
time.wHour = new_time.wHour;
time.wMinute = new_time.wMinute;
time.wSecond = new_time.wSecond;
time.wMilliseconds = 0;
}
else
{
TRACE(_T("not a time format\n"));
return;
}
CString str(_T(""));
//set the date and time
if (!SetLocalTime(&time))
{
str.Format(_T("system time error = %d. \n"), GetLastError());
TRACE(str);
return;
}//here the stack overflow message shows up; it only happens the first time i turn the unit on and if the user chooses new values only for the date (no stack overflow when setting the time).
}
SetLocalTime doesn't return an error and sets the chosen values for date/time, even if WindowsCE crashes and it needs restarting. After restarting, the date and time can be set again without any problems...
The Disassembly Window points here: "40060198 stmdb sp!, {r0, r4, r5, lr}". I don't know if this is helpful or not...
I tried SecureZeroMemory(&time, sizeof(time)) before GetLocalTime(&time) but no change.
Thanks in advance for your help.

Sounds like a possible recursion issue. What happens if you comment out the call to SetLocalTime()?

The stack overflow message doesn't appear but the new date doesn't get set.

After SetLocalTime() is called, how many times does OnBnClickedButtonSet() get called?

Only one time..The user inputs the day, month and year and/or time and then presses on Set button which calls SetLocalTime().
|
|
|
|

Yes,I know... I was thinking that maybe SetLocalTime() calles a hidden WM_something that gives the recursion issue? Do you know if this could be the case? I couldn't find anything by searching on google or reading the function description on microsoft help page...

Set a breakpoint and find out.

The problem was calling a delete function on a timer in my base class... I have removed that function and Set button works all the time. If I put the function back on timer, the stack overflow message shows up again.
Thanks everyone for your suggestions.

This just about points to passing bad data to SetLocalTime(), any way you can check it prior to sending it to SetLocalTime()?
Are you sure m_Time.GetTime(&new_time) is returning a valid time every time (keep in mind the debugger will initialize uninitialized data but this won't be the case in the release version)?
|

Thanks.
Stack overflow happens in release mode as well.
Yes, I was thinking of that too. I checked with a breakpoint and all the values for time were all right - no weird looking data...I will run in in Debug and put a TRACE with all the time values to make sure. Also maybe calling UpdateData before SetLocalTime might help? ...I will try that too.

 You can't break and look at values on a release version (data will be bogus).

Are you sure? I've debugged a release build before. All it needed was the PDB file.

Not completely sure... I know you can break, but the values it shows you won't always be accurate (at least that's what I've found). So I don't do it at all anymore... I only use breaks in debug builds.
|
|
|
|

There is OutputDebugString() function I can use to display the values in Release mode. I will try it...

Helloo..
Help me plz............
I have two different applications (SDI).
I want to call the second application from the button click of the first (without calling the EXE).
Let me know how I can call?????

Then you need to convert it to a DLL, or a COM server.

thanks for your reply..
if i dont want to use the DLL or COM as well as the EXE, is there is any other way to execute the application???
as we know that application will open by calling the "CreateWindow" and "ShowWindow" function.
can we call such function from another application??????????

sachanratnesh wrote: can we call such function from another application
Short answer: No. Longer answer: You can use the CreateProcess[^] function, but that seems not to be what you want. Perhaps you could explain in better detail exactly what you are trying to do.
