Maybe instead of
strcpy((char*)p, (const char*)pNewContact);
you should have
strcpy(pNewContact, p);
Hope it helps.

the effective assembley lanuage for this will be as shown below
004010F8 mov eax,0<br />
004010FD mov dword ptr [ebp-4],eax
the $ is replace with 0.
why u use $ there?

the value of $ is 0 when uses marco.
if direct use,
ex:
<br />
int main()<br />
{<br />
int n<br />
_x:<br />
__asm mov [n], $<br />
printf("%d", n);<br />
}<br />
_x == n is true!!
(sorry, my engish is poor, maybe...)

hey guys.......
am here with one more...
am trying to send a packet to the serial device (rabbit300 -am 8bit microcontroller). my program is written such that is event driven/programmed.
On teh formviewpage, I update the packet on clicking a send button and have this update code inside the OnButtonSend() function. this is inside prjview.cpp file.
I also created the #define WM_SEND WM_USER + 10
And I have this member function OnSend(WPARAM wParam, LPARAM lParam) inside mainframe.cpp file and I have the code to send the packet to the serial device in it.
by what i understand on clicking send button on the formview page , i should have my packet sent automatically.
but it doesnt work.. am i suppose to do smthing...like indicate from teh prjview.cpp file to the mainframe.cpp file that send button is activated ??
how to do this?

Try to debug your program.
Set breakpoints at the interesting source code lines (like the first code line in OnButtonSend() and the first code line in OnSend()). Single-step the code. Then you will know what happens, and hopefully why.

Firstly, I set the scroll bar info:
info.nMin = 0;
info.nMax = 41;
info.nPage = 10;
info.nPos = 0;
but when I scroll the bar, the scroll bar goes to end when info.nPos = 32, why is this?
|
|
|
|
|
nMax is the maximum scroll value at the bottom of the scroll bar. nPos is the position at the top of the window. nPage is the number of items that can be displayed in the window. Therefore, the maximum nPos = nMax - nPage + 1, ie. nPos is the position at the top of the window such that the maximum item (nMax) is at the bottom of the window.

hey I have created CEdit member variable for my control. But I dont find OnInitDialog() method in my dialog.cpp file. Isnt OnInitDialog() automatically generated by classwizard?
how do i include OnInitDialog()?
-- modified at 23:22 Wednesday 28th June, 2006
I create the dialog using DoModal()
|
|
|
|
|
Add a message handler for WM_INITDIALOG message using class wizard. the u will get the OnInitDialog function.
nave
|
|
|
|
|
goto page property then click in overriders then click OnInitDialog

As long as OP wrote "classwizard" word, he/she uses VS 6.0 or older, so no "page property" to go.

so how do i do it?
can u please explain?
i receive the values in mainframe.cpp and i need to get these values and display in the dialog page that i open.
i want the edit controls in the opened dialog page to be updated with these values once i open the dialog page.

Like Naveen R already said: "Add a message handler for WM_INITDIALOG message using class wizard".
Need more details?
- select "View/ClassWizard..." menu item or press Ctrl+W.
- select your dialog class from "Class Name" combo.
- from "Messages" list select WM_INITDIALOG.
- click "Add function" then "OK" or "Edit Code".
That's all.

How to do the change using IHTML**** interface?
-- modified at 23:24 Wednesday 28th June, 2006
|
|
|
|
|
I think first you have to locate your A element.
If it contained an id or name attribute, then you would use the getElementById or getElementsByName functions of IHTMLDocument2.
Otherwise you can obtain all of A elements with getEmentsByTagName function, and then perhaps organize a loop and find your element by the value of href attribute.
After you found the element and got IHTMLElement interface, change its content using put_innerText or put_innerHTML functions.
Hope it helps.

Hi Guys,
Thanks for answering my earlier post about socket trouble. The trouble is my server stopped listening for new connections (Connrefused error when client connects) but old connections are alive & still receiving handshakes.
Clients couldn't get connected even hr's after. I've found the reason, my server works fine if connections arrives one by one, but when simultaneous connections arrive, the events(WSAWaitForMultipleEvents) which i used in loop stops triggering. Without events the server works fine (accepts simultaneous connections).
I'm posting crtical section of my code, could some one give me a possible solutions...
//code starts
s = socket(AF_INET,SOCK_STREAM,0); //created
bind(s,...) == SOCKET_ERROR ) //bind
listen(s,SOMAXCONN) == SOCKET_ERROR ) //listen
CClientThread *newclient;
//The following lines are causing truble when many connections arrive simultaneously, suspect WSAWaitForMultipleEvents
WSAEVENT hEvent1 = WSACreateEvent();
WSAEventSelect (server_socket, hEvent1, FD_ACCEPT);
WSAEVENT pEvents[2];
pEvents[0] = hEvent1; // Socket event
pEvents[1] = GetStopEvent(); // Thread teminate event
BOOL bDone = false;
while ( !bDone)
{
int nRetVal = ::WSAWaitForMultipleEvents(2, pEvents, FALSE, 0, FALSE);
switch (nRetVal)
{ //when too many connections arrive at a time, this case never triggers
case WSA_WAIT_EVENT_0:
// Connection to accept
SOCKET client_socket;
client_socket = accept(s,,...);
if ( client_socket == INVALID_SOCKET )
closesocket(client_socket);
return(0);
}
newclient = new CClientThread(this,client_socket,client_ip, iPort);
newclient->StartThread();
WSAResetEvent (hEvent1);
break;
case WSA_WAIT_EVENT_0+1:
bDone = TRUE; // Thread requested to stop
break;
case WSA_WAIT_TIMEOUT:
break; // Timeout
}
}
WSACloseEvent (hEvent1);
//Code ends
Thank you
Rove
