    Here are some examples for people that want to write programs in C/C++

    Make sure iostream and windows.h are always included by trying any of these examples

    #include
    #include

    Getting Text (Last Line Written)

    int main() {
HWND mywindowclass = FindWindow("DlgGroupChat Window Class", NULL);
HWND wtlsplitterwindow = FindWindowEx(mywindowclass, 0, "wtl_splitterwindow", NULL);
wtlsplitterwindow = FindWindowEx(wtlsplitterwindow, 0, "wtl_splitterwindow", NULL);
wtlsplitterwindow = FindWindowEx(wtlsplitterwindow, 0, "wtl_splitterwindow", NULL);
wtlsplitterwindow = FindWindowEx(wtlsplitterwindow, 0, "wtl_splitterwindow", NULL);
HWND atlfe = GetWindow(wtlsplitterwindow, GW_CHILD);
HWND atlaxwin = FindWindowEx(atlfe, 0, "atlaxwin71", NULL);
atlaxwin = FindWindowEx(atlfe, atlaxwin, "atlaxwin71", NULL);
HWND x = FindWindowEx(atlaxwin, 0, "#32770", NULL);
HWND richedita = FindWindowEx(x, 0, "richedit20a", NULL);

// Error Checking:
if (!mywindowclass) { printf( "E_WINDOW_NOT_FOUND"); }
if (!wtlsplitterwindow) { printf( "E_WINDOW_NOT_FOUND"); }
if (!atlfe) { printf( "E_UNABLE_TO_FIND_PARENT"); }
if (!richedita) { printf( "E_RICHEDIT_NOT_FOUND"); }

long lngCount = SendMessage(richedita, EM_GETLINECOUNT, 0, 0);
long lngLength = SendMessage(richedita, EM_LINELENGTH, lngCount-2, 0);
TCHAR strBuffer[1024]; *(WORD *) strBuffer = 1024;
LRESULT bla = SendMessage(richedita, EM_GETLINE, lngCount-2, (LPARAM)(LPCSTR)strBuffer);
printf(" Text: %s nn", strBuffer);

system("pause"); // Testing blah

return 0;
}

    Sending Text

    int main() {
HWND parent = FindWindow("DlgGroupChat Window Class", NULL);
HWND child = FindWindowEx(parent, 0, "WTL_SplitterWindow", NULL);
child = FindWindowEx(child, 0, "WTL_SplitterWindow", NULL);
child = FindWindowEx(child, 0, "WTL_SplitterWindow", NULL);
child = FindWindowEx(child, 0, "WTL_SplitterWindow", NULL);
HWND alt = GetWindow(child, GW_CHILD);
alt = FindWindowEx(alt, 0, "AtlAxWin71", NULL);
alt = FindWindowEx(alt, 0, "#32770", NULL);
HWND rich20 = FindWindowEx(alt, 0, "RichEdit20A", NULL);
rich20 = FindWindowEx(alt, rich20, "RichEdit20A", NULL);
TCHAR mytext[25] = "Hello World!";

SendMessage(rich20, WM_SETTEXT, strlen(mytext), (LRESULT)(LPCSTR)mytext);
SendMessage(rich20, WM_KEYDOWN, 13, 0);
printf("Text: %s -- has been sent", mytext);
return 3;
}

     

    Lock Microphone

    int main() {
HWND dlggroupchatwindowclass = FindWindow("dlggroupchat window class", NULL);
PostMessage(dlggroupchatwindowclass, WM_COMMAND, 33340, 0);
return 0;
}

    Free Microphone

    int main() {
HWND dlggroupchatwindowclass = FindWindow("dlggroupchat window class", NULL);
PostMessage(dlggroupchatwindowclass, WM_COMMAND, 33343, 0);
return 0;
}

    Raise Hand

    int main() {
HWND dlggroupchatwindowclass = FindWindow("dlggroupchat window class", NULL);
PostMessage(dlggroupchatwindowclass, WM_COMMAND, 901, 0);
return 0;
}

    public static string GetRichTextLine(IntPtr richedita)
{
int nblines = SendMessage(richedita, EM_GETLINECOUNT, 0, 0);
int linelength = SendMessage(richedita, EM_LINELENGTH, nblines - 2, 0);

IntPtr lpLocalBuffer = IntPtr.Zero;
lpLocalBuffer = Marshal.AllocHGlobal(linelength+ 1);
SendMessage(richedita, EM_GETLINE, nblines - 2, lpLocalBuffer);
string retval = Marshal.PtrToStringAnsi(lpLocalBuffer);
if (lpLocalBuffer != IntPtr.Zero)
Marshal.FreeHGlobal(lpLocalBuffer);

return retval;

}

    or turn on your project to accept unsafe code to use this unsafe function

    public static unsafe string GetRichTextLine(IntPtr handle, uint line)
{
int i = 0;
int linelength = SendMessage(handle, EM_LINELENGTH,(int) line, 0);
byte[] buffer = new byte[linelength + 1];
buffer[1] = 1;
fixed (byte* ptr = buffer)
{

i = SendMessage(handle, EM_GETLINE, line, (void*)ptr);
}

if (i == 0)
return null;
ASCIIEncoding ae = new ASCIIEncoding();
buffer[linelength] =13;

string s = ae.GetString(buffer);
buffer = null;
ae = null;
return s;

}

    remember use unsafe function must import api win32 as unsafe like this

    [DllImport("user32.dll")]
static extern unsafe int SendMessage(IntPtr hWndControl, uint msg, uint wParam, void* lParam);

    now you have 2 methods to get the last line of pt text chat
    but I have an other method; I dont like this third method but I will show you also

    static string GetWindowText(IntPtr hwnd)
{
int lgText = SendMessage(hwnd, WM_GETTEXTLENGTH, IntPtr.Zero, IntPtr.Zero) + 1;
#if STRING
string sbTitle = new string('0',lgText);
#else
StringBuilder sbTitle = new StringBuilder(lgText);
#endif
SendMessage(hwnd, WM_GETTEXT, (IntPtr)lgText, sbTitle);
return sbTitle.ToString();
}

    with this you get all the text and use split function to split like this

    String s=GetWindowText( hRich);
String[] s2=s.split('n');
String lastline=s2[s2.length-2);

    I tell you what SassyJasmine, You can’t get any to work because they people just Copy + Paste and these codes are simply faulty ;).

    I wont code it for you, just show u the way. try to do a search yourself on how to interop unmanaged function with managed project. Man when I code it, no one show me a hint like that, so you are lucky than me

    Glactica I think u r the silliest girl or guy on earth lol

    ok I will show the the step by step to get the last line of richtext control pt room

    first import some api const and function.

    to able to use this function

    public static string GetRichTextLine(IntPtr richedita)
{
int nblines = SendMessage(richedita, EM_GETLINECOUNT, 0, 0);
int linelength = SendMessage(richedita, EM_LINELENGTH, nblines - 2, 0);

IntPtr lpLocalBuffer = IntPtr.Zero;
lpLocalBuffer = Marshal.AllocHGlobal(linelength+ 1);
SendMessage(richedita, EM_GETLINE, nblines - 2, lpLocalBuffer);
string retval = Marshal.PtrToStringAnsi(lpLocalBuffer);
if (lpLocalBuffer != IntPtr.Zero)
Marshal.FreeHGlobal(lpLocalBuffer);

return retval;

}

     

    before your form1 class; you will see some code using System; …ect
    after right there you have to do this

    using System.Runtime.InteropServices;

    and in your form1 class public declaration import some api like this

    public const int EM_GETLINE = 196;
public const int EM_GETLINECOUNT = 186;
public const int EM_LINELENGTH = 193;
[DllImport("user32.dll", EntryPoint = "SendMessage")]
public static extern int SendMessage(
IntPtr hwnd, int wMsg, int wParam, int lParam);

[DllImport("user32.dll", EntryPoint = "SendMessage")]
public static extern int SendMessage(IntPtr hwnd, int Msg, int wParam, IntPtr lParam);

    just add this class to your project and here is example to use this class

    String room = Win32ForPaltalk.WIN32PaltalkApi.GetPaltalkRoomName(); //get the active pt room name;

    Win32ForPaltalk.WIN32PaltalkApi.sendPalx(“your text”, room);

    and more… just learn that class
