How do I get text from a Win2 rich edit

[MsPhelix]

Hi,

I have a rich edit displaying just fine on my Win32 app; it is created as follows

	LoadLibrary(TEXT("Msftedit.dll"));

	g_hRichEdit = CreateWindowEx(WS_EX_CLIENTEDGE,
		_T("RICHEDIT50W"),
		_T("My Rich Edit"),
		WS_BORDER | WS_CHILD | WS_VISIBLE | ES_MULTILINE,
		2, 2,
		500, 300,
		hWnd,
		(HMENU)IDC_RICHEDIT,
		hInstance,
		NULL);

I think I need to use GetDlgItemText()get the text, but then I have an issue with the id param

GetDlgItemText(hWnd, WHAT GOES HERE?, g_szInput, MAXCHAR);

I put in IDC_RICHEDIT from the CreateWindowEXx() call; I didn't think that would work and it didn't: the app built and ran but after the GetDlgItemText() call, g_szInput was NULL or the value I initialized it to.

How am I suppose to do this? Once again the examples and discussions simple say use GetDlgItemText() but don't explain how.

Do I need to put the rich edit in a .rc file so it has an id? If so, how?
Please give complete code.

Thank you for responding but your answer is useless.

I looked at that page and it says nothing about how to get text from the rich edit. If you can show me on that page or any page it leads to that I am wrong and the answer IS there, I will apologize abjectly.

I'm sorry if I'm being overly snippy, but from several posts I've put on this forum, far too many responders (not all by any means) toss out a quick link to some page without knowing whether it actually answers the question. A further beef I have is responders who say do this or that and don't give the needed headers for the functions or variables they are telling you to use.

you can use GetWindowTextLength and then GetWindowText.

i changed code from your other topic:

#include <windows.h>
#include <tchar.h>
#include <Richedit.h>

// Global variables
static TCHAR szWindowClass[] = _T("win32app");
static TCHAR szTitle[] = _T("Test Rich Edit Control");

// THE RICH EDIT CONTROL
HWND g_hRichEdit = NULL;

// Forward declarations of functions
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,

	wc.style = 0;
	wc.lpfnWndProc = WndProc;

	wc.hInstance = hInstance;
	wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
	wc.hCursor = LoadCursor(NULL, IDC_ARROW);

	wc.lpszMenuName = NULL;
	wc.lpszClassName = (LPWSTR)szWindowClass;

	if(!RegisterClassEx(&wc))
	{

	hWnd = CreateWindowEx(

                        nLen = GetWindowTextLength( g_hRichEdit);

                            delete [] buffer;

Thank you, that is what I needed :)
