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.

How to exit from ModalLoop ?

Gopakumar4-May-05 20:28

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.

I am trying to receive the TV remote signal using the ipaq 3115.

The IR port on the pocket pc is Port 3. Its opened and configured. No errors there.

I constantly poll the port for any data. But I am getting none.

Here's my code -

BYTE rx;
int rcd[30];
int i=0;
DWORD dwbytesTransferred=0;
long one;

while(1)
{

one = ReadFile(m_irport, &rx, 1, &dwbytesTransferred, NULL);

if (dwbytesTransferred > 0)
{
rcd[i]=rx;
m_rcv="Data In";
UpdateData(FALSE);
i++;

}
else
{
m_rcv="No Data";
UpdateData(FALSE);
}

}

Any help would be greatly appreciated. Thanks.

4-May-05 18:05

hi all
i wrote the following function to append one project's accelerators to another because i thought there was no function doing that. but it has a problem, +10 (something more than 2) is required. why?

status appendAcceleratorsTable(HACCEL &hAccel,LPCTSTR lpszResourceName)<br />
{<br />
	// locate and load new accelerators<br />
	HINSTANCE hInst=AfxFindResourceHandle(lpszResourceName,RT_ACCELERATOR);<br />
	ASSERT(hInst);<br />
	HACCEL hNewAccel=LoadAccelerators(hInst,lpszResourceName);<br />
	ASSERT(hNewAccel);<br />
<br />
	// calculate number of accelerators in both tables<br />
	int numAccel=CopyAcceleratorTable(hAccel,NULL,NP);<br />
	int numNewAccel=CopyAcceleratorTable(hNewAccel,NULL,NP);<br />
<br />
	// allocate a global space to hold both accelerator tables<br />
	LPACCEL lpAccel=(LPACCEL)GlobalAlloc(GPTR,(numAccel+numNewAccel+10)*sizeof(ACCEL));<br />
	ASSERT(!lpAccel);<br />
<br />
	// copy both tables in it<br />
	VERIFY(CopyAcceleratorTable(hAccel,lpAccel,numAccel)==numAccel);<br />
	VERIFY(CopyAcceleratorTable(hNewAccel,lpAccel+numAccel,numNewAccel)==numNewAccel);<br />
<br />
	// remove the previous ones and finalize<br />
	DestroyAcceleratorTable(hNewAccel);<br />
	hNewAccel=CreateAcceleratorTable(lpAccel,numAccel+numNewAccel);<br />
	ASSERT(hNewAccel);<br />
	VERIFY(CopyAcceleratorTable(hNewAccel,NULL,NP)==numAccel+numNewAccel);<br />
	DestroyAcceleratorTable(hAccel);<br />
	hAccel=hNewAccel;<br />

Assembly questions

I'm interested in doing some work with Assembly. Does anyone know any good resources on the web for learning Win32 assembly from start to finish (coding to compiling)?

Additionally, I have a dll module that I want to decompile, modify, and recompile. Does anyone know how to do this, or know of resource through which to do it? (This is a module that I will NOT be redistributing, it's for my own tinkering pleasure)

Thanks for the help. Sorry if this is OT.

Can you elaborate on your function details?
It's much better if you could post your function definition (function body).

This makes no sense at all. Technically speaking, exceptions are thrown. Please provide a code snippet of what you are trying to do, the value(s) that you are getting, and the value(s) you want instead. Provide as much pertinent details as necessary.
