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.

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

hi all ,
i am facing a problem while displaying 2 byte japanese characters in web page.
actually what i m doing is reading the japanese string as a string and then writting it to xml file and then use the xml file to fill the web page .
so what i m getting is single byte characters corresponding to the the japanese chracters.
If anyone has any answer then please reply

Actually the constraint is that we should not mention any encoding in the XML file
Surendra Vishwkarma

He is referring to the header of the XML which generally indicates that the XML is encoded using UTF-8. When writing the XML, you probably need to convert the native UNICODE string to UTF-8.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Anyone know the reason why the WS_MAXIMIZE style bit isn't taking effect when I don't also specify the WS_POPUP for the window's style? MSDN doesn't suggest it's ignored, although a quick Google leads me to believe it could be for overlapped windows.
I need to initially maximize a window during the app startup. I've always used ShowWindow() in the past when maximizing a window without much headache, but now I need to control the order in which this happens moreso to avoid unsightly drawing issues as I need to perform quite a few tasks during the startup (working on my first 3D game). As such, I'd rather have it maximized before the window is shown rather than after and don't want to go through the trouble of screwing around with the message queue to deal with it.
Surely there must be a simple way for an overlapped window?
TIA

That doesn't work either (just tested, it's still ignored), unless I use it after the window has been shown, which means I still get the flickering during startup.
[edit] Ok, I made a couple changes with the queue and got it to maximize, but I still get the drawing issues that I do with ShowWindow(). Now, pardon me while I beat my head against the wall.  [/edit]
Thanks for the reply though.

I got rid of the flicker by adding a couple of painting ops (hope it doesn't mess me up down the read as I'm new to OGL).
But, if anyone knows why CreateWindow() doesn't honor WS_MAXMIMIZE for anything but a popup, you'd be my new hero for the day. Either way, thanks for watching me whine.
