how do i include OnInitDialog()?

Add a message handler for WM_INITDIALOG message using class wizard. the u will get the OnInitDialog function.

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

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?

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

A.exe use createprocess to start up B.exe,
B.exe must read a local file in its folder,
i found i only click B.exe, B.exe can open the local file,
when A.exe start up B.exe using createprocess,
B.exe fails to open the local file always.
Why?
Just relax
|
|
|
|
|
how do u try to open the file? Try opening the the file using the full path not relative.
I doubt the problem happens because of the change in the working directory of the b.exe.

I have try both full path and relative,
but have the same problem.
Just relax

Can you show how to use.

Main process:
STARTUPINFO si;
ZeroMemory(&si, sizeof(si));
si.cb = sizeof STARTUPINFO;
PROCESS_INFORMATION pi;
CreateProcess("A.exe",
NULL,
NULL,
NULL,
FALSE,
0,
NULL,
NULL,
&si,
&pi);
Sub Process:
GetModuleFileName(NULL,read,1000);
printf("%s\n",read);
int len = strlen(read);
strcpy(read+len-4,".tmp");
printf("%s\n",read);
FILE *f = fopen(read,"rb");
if (f==NULL) {
printf("Hello world\n");
}
Just relax

u try opening the file in write mode.
if that too failes, u can conclude one of the following
1. A file already exist in that path and is been opened by another process
2. Path is invalid
3. Don't have privilage
and let me know the results

If fopen() fails, what is the value of errno?

You should be telling us why.  If you are opening the file via CreateFile() and it's failing, what does GetLastError() return?

It's too strange!!!
STARTUPINFO si;
ZeroMemory(&si, sizeof(si));
si.cb = sizeof STARTUPINFO;
CHAR szFolderWhereFileIsLocated[250]={0};
strcpy(szFolderWhereFileIsLocated ,"put path here");
PROCESS_INFORMATION pi;
CreateProcess("A.exe",
NULL,
NULL,
NULL,
FALSE,
0,
NULL,
szFolderWhereFileIsLocated,
&si,
π);
when i put these code in a console program, the sub process can open correctly. Then in my windows program, the sub process can't open file firstly, then start up the sub process again (my program will start up the sub process every 20 sec) , it's OK.
Just relax
