When the executable file are executed there are several steps: for example,
first run to line 34, then line 55-78 are executed, after this a function block are executed, ..., at last the window is destroyed. Of course, there maybe are some messages to be handled during the time.

I want to know the function's inter-calling way. Blush | :O

Registry problems

Hi All,

I am developing an application for Windows 2000/XP using VC++.I want to make a complete copy of

"Current Controls Set" in my application. (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet) to

another key in HKEY_LOCAL_MACHINE.

For copying the key I referred http://www.codeproject.com/system/registrykeycopy.asp code.

The program is working perfectly fine. But when i try to copy the CurrentControlSet key, it

copies all the keys except the "Enum key".

I think there is some security reason behind this. If this is so, then can anybody please suggest

a way to copy this key also.

Or alternatively is there any other way to copy this whole key including Enum key.

Please suggest!

What is the XP Accessibility Wizard doing?

On many XP machines, our software is displayed with its view’s truncated. I have looked at the Control Panel / Accessibility Options and everything seems correct. (No vision related properties are checked.)

I can correct the problem by running the Accessibility Wizard. I just run the Wizard, clicking on NEXT for everything – I change no options. This process fixes the problem 100% of the time.

My guess is this process of running the Accessibility Wizard is doing something to the registry. But what is it doing? How can I find out what the Wizard does?

Thanks

problem using CDialog::Create, assert error

Hello everybody,
Here is my problem.
I'm trying to display a dialog and in the Create() function I'm getting an assert error. I dig up through the debugger and I found out where I'm getting the assert error is in AfxGetResourceHandle(). Here is my code:

int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
 	// TODO: Place code here.
	CMainDlg *mainDlg = new CMainDlg(); //Base class is a CDialog
	BOOL bRet = mainDlg->Create(IDD_MAIN_DIALOG, NULL); //-->I'm getting the assertion error here!
	if (bRet != 0)
	{
		mainDlg->ShowWindow(SW_SHOW);
	}
	else if(bRet == 0)
	{
		AfxMessageBox("Error Creating Dialog");
	}

	return 0;
}

As you noticed, all I'm trying to do is to display a dialog. Is there anything that I have to set in advance before I create the dialog and display it? Any answer is more than welcome.

Best regards,

It has been a long time since I have done MFC, but since you have replaced MFCs WinMain, it has been unable to initialize.

What you should have done is display your dialog from the InitInstance method of your CApplication class.

I'm going to patent thought. I have yet to see any prior art.

Have you stepped through the Create() code to see why afxCurrentResourceHandle is still NULL?

Luis E. Cuadrado11-Jun-03 4:13

Hi DavidCrow,
Yes, I stepped through the Create() code. The assertion is comming in the AfxFindResourceHandle() function. I included the portion of the code where the assert error comes and I pointed out where the assert error occurs. Aparently the value pModuleState->m_bSystem returned by AfxGetModuleState() is causing the assert error. Here is the code.

HINSTANCE AFXAPI AfxFindResourceHandle(LPCTSTR lpszName, LPCTSTR lpszType)
{
	ASSERT(lpszName != NULL);
	ASSERT(lpszType != NULL);

	HINSTANCE hInst;

	// first check the main module state
	AFX_MODULE_STATE* pModuleState = AfxGetModuleState();
	if (!pModuleState->m_bSystem)
	{
		hInst = AfxGetResourceHandle(); //-->ASSERT OCCURS HERE!!!
		if (::FindResource(hInst, lpszName, lpszType) != NULL)
			return hInst;
	}
.
.
.

I hope this helps. Before I forget, thanks for your reply David

Technically, the assertion is being fired within the inline function AfxGetResourceHandle(), which, in this case, is being called by AfxFindResourceHandle(). Have you tried Tim's suggestion? I've never tried creating an MFC application without the other supporting pieces in place.

I'm going to try Tim's suggestion. As soon as I find something, I will post back the results.

SHChangeNotifyRegister Questions!!!

Ryan Binns11-Jun-03 5:03

Simple. In order to use MFC you must initialise it first.

if(!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
    // MFC failed to initialise properly
    return 1;
}

Then your MFC operations will work as normal Smile | :)

. You don't need to call any cleanup functions at the end.

I use SHChangeNotifyRegister api to monitor the filesystem notification.
But I find when I copy a lot of files(>=20),The number of the posted notification: SHCNE_CREATE not equals to the number of the files. the Shell allways post about 10 SHCNE_CREATE notification, then follow a SHCNE_UPDATEITEM notification, This is not the acion I need.
Does anything wrong. But If the number of files to copy is less than 10,All is right.
How to do? help!!!

any wrong?

David Crow11-Jun-03 4:42

11-Jun-03 4:42

Looks fine. The shell also only has a 10-item event buffer, and may replace some events with a generic SHCNE_UPDATEDIR in case of an overflow. In short: don't depend on these notifications for any mission-critical applications.

How do you know this? How can you tell that it is receiving more than 10 notifications?

how to add icon to system imagelist?

11-Jun-03 5:28

I copy files to a folder, there are thousands files in that folder.
If flush the display of this folder, it will take mostly 2 second and cpu usage maybe nearly 100%.
But I find the cpu usage of explorer is only 10%, and last no more than 1 second, and the display is right, how do you thant about it?
