Hi
I am using a rih edit control in my SDK app. So when i was executing the app i got the "Cannot find window class" error when i tried to call CreateDialog(..).
So i did the following
INITCOMMONCONTROLSEX init;
memset(&init, 0, sizeof(init));
init.dwSize = sizeof(INITCOMMONCONTROLSEX);
init.dwICC = ICC_STANDARD_CLASSES;
InitCommonControlsEx(&init);
Now i get an error that 'ICC_STANDARD_CLASSES' : undeclared identifier even when commctrl.h and comctl32.lib are properly used.

Per MSDN, ICC_STANDARD_CLASSES is not a valid option.
Prior to creating the control, I think you might need to call LoadLibrary("riched20.dll") .

The rich edit control is initialized differently than other controls. You need to load either riched32.dll or riched20.dll in your app's init code, depending on which rich edit version you need.

Hi all,
Can we declare constructor in private section?

Yes you can. But if you want to create an object of that class, you will need a public static member function in the class to create the object for you.

If I want to create an object of that class whose constructor is private and dont want a static member function to create an object then?

you can create a factory class and declare it as a friend of your class. what exactly are you trying to achieve?
|
|
|
|
|
Trying to achieve nothing. Just finding out the answers, these questions are asked generally everywhere in interviews. Can you do that without a friend class also?

the purpose of private constructors is to make it impossible for clients to call them as they wish. 2 ways to do it should be quite enough, it wouldn't make sense to make them private and provide ten other ways to call them.
|
|
|
|
|
yes you can (why couldn't you ?), but the only reason you might want to do this is to let it do some common initializations ; then you could call it from another constructor of the same class...

Hello..
I am using MCI for recording sound.. I am using the sample code given in MSDN for recording.. This allows me to record sound only for specified amount of time.. I want to generalise it so that, recording stops when i click on the stop button..
At present what i am doing is as follows:
void CCNPhoneAdapterDlg::OnRecord()
{
RecordWaveFile(10000);
}
DWORD CCNPhoneAdapterDlg::RecordWaveFile(DWORD dwMilliSeconds)
{
// Begin recording and record for the specified number of
// milliseconds. Wait for recording to complete before continuing.
// Assume the default time format for the waveform-audio device
// (milliseconds).
mciRecordParms.dwTo = dwMilliSeconds;
if (dwReturn = mciSendCommand(wDeviceID, MCI_RECORD,
MCI_TO | MCI_WAIT, (DWORD)(LPVOID) &mciRecordParms))
{
mciSendCommand(wDeviceID, MCI_CLOSE, 0, NULL);
return (dwReturn);
}
// Save the recording to a file named TEMPFILE.WAV. Wait for
// the operation to complete before continuing.
mciSaveParms.lpfilename = "tempfile.wav";
if (dwReturn = mciSendCommand(wDeviceID, MCI_SAVE,
MCI_SAVE_FILE | MCI_WAIT, (DWORD)(LPVOID) &mciSaveParms))
{
mciSendCommand(wDeviceID, MCI_CLOSE, 0, NULL);
return (dwReturn);
}
return (0L);
}
................
Also i want to allow the user to specify the location and file name to store the recorded sound.
Can anyone help me?

Friends,
I've made an application which is automating MS-Word. I run MS-WORD from my application and my application receives events happening in that instance of MS-Word.
I want to detect keyboard events in that instance of MS word inside my application. Actually i want user to type some string in Word and press some key like Ctrl-A. As such i want MS-Word no notify my application. Is it possible with automation ?? If not then what is the solution.

if the button is not on border (NC area), just move it to there by MoveWindow(). otherwise, u need to draw NC area urself to prevent the button from being painted (covered) by default NC drawing.

I created a modal dialog box which is a third level child.
I override the CDialog DoModal function and made the first level child as the owner of this modal dialog, so that this dialog will be modal only up to first level. Hence the main dialog can be activated. Before main dialog is getting destroyed, I'm destroying all the child dialogs.
While modal dialog is displaying, if I destroy the main dialog, I'm getting assertion. The problem is modal loop is still valid.
I called the function EndModalLoop() before destroying the dialog window, still the problem exist.
How to stop/exit modal loop ?
|
|
|
|
|
|
EndDilaog() also closes the dialog window but not stop the modal loop.
The combination of EndModalState() and EndModalLoop(ID_CANCEL)will solve this issue.
Is this right way of handling this problem ?
Is any other way we can solve this issue ?

Hi,
Thanks for the reply.
I have the toolbar data in my application which is generally stored in the Registry.I want to store the Docking and floating information of the tool bars to be stored in the xml file rather than the registry and when i try to start my application it should be able to load that info from the xml file.Usually CDockState is a an MFC class which is used to store the info reg the docking and floating of the toolbar to the registry.
