Hello!
I'm working with an MFC dialog based app and am using:
SendMessage(GetDlgItem(hDlg, IDC_EDIT_CHATLOG),
EM_EXSETSEL, 0, (LPARAM)&ch);
But I don't have a way to get the hDlg parameter which is the handle to the window.
Anyone know how to get the handle to an mfc dialog box win?
thanks in advance,
jay

That depends on where that code is. Is it in a member function of the dialog? If so, just use the CWnd wrapper:
SendDlgItemMessage(IDC_EDIT_CHATLOG, EM_EXSETSEL, 0, (LPARAM)&ch); Otherwise, use AfxGetMainWnd() to get a pointer to the main window:
AfxGetMainWnd()->SendDlgItemMessage(...);

Hi,
you can use one of the following 3 methods to retreive the handle of a control
1. insinde the dialog you can get a window object of the control:
CWnd* pWnd = GetDlgItem(IDC_EDIT1);
HWND hWnd = pWnd->GetSafeHwnd();
2. insinde the dialog you can get the handle of the control:
HWND hWnd2 = NULL;
GetDlgItem(IDC_EDIT1, &hWnd2);
3. from anywhere you can get a handle of a control by using:
HWND hWnd3 = ::GetDlgItem(pDlg->GetSafeHwnd(), IDC_EDIT1);
if you need to get a unknown window you'v got to find it using the following code:
HWND hwndThis = ::FindWindow(NULL, _T("DlgTest"));where _T("DlgTest") is the caption of the window you are looking for

Awesome except I need the handle to the MFC dialog window!

What do you mean with the MFC dialog window!
codito ergo sum

The HWND handle to the MFC dialog box, I think AfxGetMainWnd() will work but for some reason I've been having a bit of trouble trying to implement it in a small UDP voice chat server app.

Hi,
can you be a little specific of the location in code from where did you try to
get the handle of the dialog?
Is it from a thread handling the UDP connection and is the dialog you reffer to the main
dialog of a dialog base application. In that case you should give the handle to the window/dialog
via a paramter to the thread when constructing the thread.
Or could you tell me a little more of the design of your application so that i can spot
your problem

Yea I'm sorry guys I should have been more descriptive.
I've figured it out now, but basically all I was trying to do was log messages to an edit box control inside an mfc dialog based app in a CString. Now initially I was trying to do this from inside the server's functions, which I then realized all I needed was to either it global or pass it to each server's functions. Then I couldnt figure out why the strings weren't being added to the log window correctly, then I saw I needed to go inside the Dialog's Timer function where I handle my updating for my server and refresh the window every 60th of a second.
All in all it was more of the fact I forgot where I needed to call what, exactly as you said. I'll remember to be more specific next time, but the help was much much appreciate and used!

Im using MS VS 2005. I made a solution, built a solution in realease, and tested on my computer. My program worked well. But when I copied the realease to another computer, it didnt run ( an error and advice "reinstall your application "!!!). I checked all the dll (in my solution, just 1), and test in many computers, but it still broken. But It still run well on my computer. What's the problem ???

I found function online that some how manipulates the byte order of a program and writing a jmp, where its not ariginally at http://www.devx.com/Intel/Article/21023/2046[^]
but what id like to know is how to get a function like this to skip a process calls like, TerminateProcess() or ExitProcess().
*or simply how would i get a remote application from closing or maybe just filterring the wm_close to reach that window in c++?

I am trying to output to the console and trying to center words on the screen. I realize that I cold assume 80 characters can be displayed across - its pretty much the absolute standard these days - but I was wondering if anyone knows a function to get the character width of the console output so that I can use that to be a little more universal in my centering function. Anyone know?

I found the code that you want in here.
http://www.koders.com/c/fidD1457B7594BFF764B76CFFDBCD7E2EDE2E4188C3.aspx?s=telnet
And I tested it like below, and I could get the result;
// consoletest.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <windows.h>
#include <conio.h>
void SetConsoleSize(HANDLE hConsole, SHORT xSize, SHORT ySize)
{
CONSOLE_SCREEN_BUFFER_INFO csbi; /* hold current console buffer info */
BOOL bSuccess;
SMALL_RECT srWindowRect; /* hold the new console size */
COORD coordScreen;
bSuccess = GetConsoleScreenBufferInfo(hConsole, &csbi);
/* get the largest size we can size the console window to */
coordScreen = GetLargestConsoleWindowSize(hConsole);
/* define the new console window size and scroll position */
srWindowRect.Right = (SHORT) (min(xSize, coordScreen.X) - 1);
srWindowRect.Bottom = (SHORT) (min(ySize, coordScreen.Y) - 1);
srWindowRect.Left = srWindowRect.Top = (SHORT) 0;
/* define the new console buffer size */
coordScreen.X = xSize;
coordScreen.Y = ySize;
/* if the current buffer is larger than what we want, resize the */
/* console window first, then the buffer */
if ((DWORD) csbi.dwSize.X * csbi.dwSize.Y > (DWORD) xSize * ySize)
{
bSuccess = SetConsoleWindowInfo(hConsole, TRUE, &srWindowRect);
bSuccess = SetConsoleScreenBufferSize(hConsole, coordScreen);
}
/* if the current buffer is smaller than what we want, resize the */
/* buffer first, then the console window */
if ((DWORD) csbi.dwSize.X * csbi.dwSize.Y < (DWORD) xSize * ySize)
{
bSuccess = SetConsoleScreenBufferSize(hConsole, coordScreen);
bSuccess = SetConsoleWindowInfo(hConsole, TRUE, &srWindowRect);
}
/* if the current buffer *is* the size we want, don't do anything! */
return;
}
int main(int argc, char* argv[])
{
HANDLE hStdout;
hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleSize(hStdout, 100, 100);
printf("1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890\n");
getch();
return 0;
}

Did you download latest SDK in here[^]?
But I didn't try to test the func so it's not exactly for the problem.
