I posted a little earlier with a sendmessage issue and we came to the conclusion that it would be extremely hard to get the chat window from Xchat. I have now moved to ThrashIRC and using spy++ was able to find the chat window(highlighted):
As you can see it does have a caption which means that it does see the text. Here is the code that I am using to get the HWND's and the text:
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <iostream>
#include <strsafe.h>
using namespace std;
void FindThrash()
{
cout << "[ThrashIRC]" << endl;
cout << "| find ThrashIRC window" << endl;
HWND hwndThrashIRC = FindWindow(L"ThrashIRC", NULL);
if (NULL != hwndThrashIRC)
{
cout << " + found ThrashIRC window" << endl;
cout << "| find MDIClient window" << endl;
HWND hwndMDIClient = FindWindowEx(hwndThrashIRC, NULL, L"MDIClient", NULL);
if (NULL != hwndMDIClient)
{
cout << " + found MDIClient window" << endl;
cout << "| find DefChannel window" << endl;
HWND hwndDefChannel = FindWindowEx(hwndMDIClient, NULL, L"DefChannel", NULL);
if (NULL != hwndDefChannel)
{
cout << " + found MDIClient window" << endl;
cout << "| find RichEdit20W window" << endl;
HWND hwndRichEdit20W = FindWindowEx(hwndDefChannel, NULL, L"RichEdit20W", NULL);
if (NULL != hwndRichEdit20W)
{
cout << " + found RichEdit20W window" << endl << endl;
cout << "- get text " << endl;
const int bufferSize = 32768;
char textBuffer[bufferSize] = "";
SendMessage(hwndRichEdit20W, WM_GETTEXT, (WPARAM)bufferSize, (LPARAM)textBuffer);
cout << "[begin text]" << endl;
cout << textBuffer << endl;
cout << "[end text]" << endl;
}
else
{
cerr << "RichEdit20W not found." << endl;
}
}
else
{
cerr << "DefChannel not found." << endl;
}
}
else
{
cerr << "MDIClient not found." << endl;
}
}
else
{
cerr << "ThrashIRC not open." << endl;
}
}
void ErrorExit(LPTSTR lpszFunction)
{
// Retrieve the system error message for the last-error code
LPVOID lpMsgBuf;
LPVOID lpDisplayBuf;
DWORD dw = GetLastError();
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
dw,
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
(LPTSTR)&lpMsgBuf,
0, NULL);
// Display the error message and exit the process
lpDisplayBuf = (LPVOID)LocalAlloc(LMEM_ZEROINIT,
(lstrlen((LPCTSTR)lpMsgBuf) + lstrlen((LPCTSTR)lpszFunction) + 40)*sizeof(TCHAR));
StringCchPrintf((LPTSTR)lpDisplayBuf,
LocalSize(lpDisplayBuf) / sizeof(TCHAR),
TEXT("%s failed with error %d: %s"),
lpszFunction, dw, lpMsgBuf);
MessageBox(NULL, (LPCTSTR)lpDisplayBuf, TEXT("Error"), MB_OK);
LocalFree(lpMsgBuf);
LocalFree(lpDisplayBuf);
ExitProcess(dw);
}
int main()
{
FindThrash();
if (!GetProcessId(NULL))
ErrorExit(TEXT("GetProcessId"));
return 0;
}
The buffer is only that large because 1: I thought it might have been an error where the buffer was to small, and 2: the buffer is going to have to be large because of the amount of text. Any suggestions / code would be greatly appreciated! Thanks!
