Wow, it really seems that you like to complicate your life. If you are doing that in a separate thread, why are you using OverlappedIO ? You could simply use a blocking read that returns when data is available.
Anyway, that's not the source of your problem. From your description, it really sounds like you didn't set the comm timeouts. Thus, when you start hyperterminal, the timeout settings are changed and that's why the behavior is different afterwards. To change the comm timeouts, you can use the SetCommTimeouts[^] function.

Hai!
I have following doubts in my Mfc application :
1. I launch sub-application from my main dialog. I implemented shortcut keys(Alt + xx) and tab-order in both main dialog as well as in the sub application. During launch of main dialog, the shortcut keys work. but on returning from the sub-application back to main dialog the shortcut keys are not working! why?
2. I implemented Tab-order in my dialog. My dialog contains 3 radio buttons as well as 2 buttons (all are in enabled manner). On launching the dialog and pressing "Tab" button the cursor moves in between the two buttons only, it doesn't select the Radio buttons. On selecting any one of the radio buttons using mouse , now on pressing "Tab", the cursor moves to both buttons as well as the selected radio button. why does this happen is there any sollution thrugh which i can select Radio buttons using "Tab"?
Thanks!

1/
No solid idea - but I suspect that your first application does not have the keyboard focus. App1.exe has it when it starts. App2.exe gets the focus when it starts later. App2.exe goes away, and NOTHING has the keyboard focus (or maybe the shell does - but not App1.exe).
If you click somewhere on App1.exe, do the keys start working again?
2/
Radio buttons are a bit fiddly for tab order.
a/ Set every control style to TABSTOP.
b/ Set the GROUP style of every control
c/ Set the tab order so the radio buttons are one after each other.
d/ Clear the GROUP style of all but the first in a group of radio buttons.

hi i am a fresher for WinCE and i am using createprocess to run one winceplayer application
once the commandline in the create process gets executed i want another files on the row to be executed
could anyone please help me in this regard
CreateProcess(_T("\\windows\\ceplayer.exe"),_T("c\\folder\\new.wmv"), NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, NULL, &processInfo);
once new is done i want next.wmv to be run
Thanks in Advance

Do you want to play the file one another?
then, createprocess will not help. Bcoz, createprocess WinAPI will trigger the command to the Windows Message Queue and it will come out. Application will not wait to process completed and it will execute next statement

Sorry for the misguide. Mentioned earlier for ShellExecute not for CreateProcess.

Thank u sethuraman.k,
Do you have any idea regarding my issue of playing the files in a row if yes guide me in this regard.
and
could you please tell me how to get the handle to the windows that have been created from createprocess(winceplayer).
so that i can use that handle to close the respective window
|
|
|
|
|
I am not sure but u just try with PROCESS_INFORMATION structure. For you "processInfo".
processInfo.hProcess contains handle to the newly created process.

Just try this:
HWND hwnd;
STARTUPINFO si;
ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
PROCESS_INFORMATION pi;
ZeroMemory( &pi, sizeof(pi) );
if( !CreateProcess(NULL,
"C:\\Program Files\\Windows Media Player\\wmplayer.exe",
NULL,
NULL,
FALSE,
CREATE_SUSPENDED,
NULL,
NULL,
&si,
&pi ) )
{
TRACE("CreateProcess failed");
}
else
{
TRACE("CreateProcess sucess");
}
hwnd = (HWND)pi.hProcess;
ShellExecute(hwnd, "open", "d:\\del\\Dancingbaby.avi", NULL, NULL, SW_SHOWNORMAL);
TRACE("sucess");

#pragma comment(lib,"Shlwapi.lib")
I personly think the code above is to load a "dll" file。Am i right or not?
Any one can help me and explain it to me,
thanks.
Besides, i am not good at English, and if there is any grammar mistake,Please point it out directly.
thanks again.

The following pragma causes the linker to search for the Shlwapi.lib library while linking. The linker searches first in the current working directory and then in the path specified in the LIB environment variable.
|
|
|
|
|
#pragma comment(lib,"Shlwapi.lib")
code will link the lib file at compile time. It never look dll at compile time. This type of linking called static linking.
Instad of this code you can add ur lib file(Shlwapi.lib) into
Project-->Settings-->Link-->Object/Library Modules-->
Shlwapi.lib

Yes, you need it in order to link with the Hammurabi code [^].

I don't think you can, without going the owner draw route, and doing lots of work.
But what can *can* easily do, is use a static control with the SS_NOTIFY style turned on, and handle the WM_COMMAND/STN_CLICKED that it send you.
Same clickability, less graphic goings-on.
Good luck,
Iain.

For Owner draw Chris Maunder has a good article about it(on the codeproject) and I suggest you see it but for buttons Custom Draw Buttons & A Smarter Groupbox[^] (A class to make working with radio buttons easier, and another for custom drawing buttons )

The __FUNCTION__ macro will give you the function name.
