Get input from textbox

[Serpent]

I created a TextBox in Win32 using the CreateWindowEx function like so:

	// Creating textbox for input
	hwnd_ed_1 = CreateWindowEx(WS_EX_CLIENTEDGE, "edit", "Line one",
                              WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER | ES_LEFT,
                              CW_USEDEFAULT, CW_USEDEFAULT, 200, 24,	// x, y, w, h
                              hwnd, (HMENU)(123),
                              (HINSTANCE) GetWindowLong (hwnd, GWL_HINSTANCE), NULL);

How can I get input from this?

Use the GetDlgItemtext function.

It doesn't look like it. How do I do it?

[Vexer]

char* string;
GetDlgItemText(hwnd, 123,  string);

[Serpent]

Okay thanks, I'll try that out.

This should be in a switch case statement shouldn't it? This is for getting input from MessageBox's anyways. >.<

char* line;

/* ... */

// Creates textbox for input
hwnd_ed_1 = CreateWindowEx(WS_EX_CLIENTEDGE, "edit", "Line one",
	WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER | ES_LEFT,
	CW_USEDEFAULT, CW_USEDEFAULT, 200, 24,	// x, y, w, h
	hwnd, (HMENU)(123),
	(HINSTANCE) GetWindowLong (hwnd, GWL_HINSTANCE), NULL);

GetDlgItemText(hwnd, 123, line, 100);
MessageBox(NULL, line, "Stuff", MB_ICONINFORMATION | MB_OK);

It doesn't matter where it is.

You should check for any change of text in this edit box...

THere is an appropriate WM for this... (I dont remember at the moment - check the msdn)...

[Serpent]

The search would be in the form of... ?

[Incubbus]

Search?... How about looking into the control library and look up for the edit box´s messages?!?...

[Vexer]

There are no messages that are sent when the edit control's data changes. I recommend that you just add a button to your form, then display the message box when you click it.

[Incubbus]

There are messages , that will be sent to the parent window´s window procedure...

[Vexer]

Yes, but there are none that are sent when the text changes. If you don't believe me, look at MSDN.

[Incubbus]

Bet on?!... I don´t want to go to the MSDN again... But since You are willing to do so, check for EN_UPDATE and EN_CHANGE :P...

EDIT: Notifications are Window Messages, too... (EN_xxx)

Got it:

// Creates textbox for input
hwnd_ed_1 = CreateWindowEx(WS_EX_CLIENTEDGE, "edit", "Line one",
	WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER | ES_LEFT,
	CW_USEDEFAULT, CW_USEDEFAULT, 200, 24,	// x, y, w, h
	hwnd, (HMENU)(101),
	HINSTANCE) GetWindowLong (hwnd, GWL_HINSTANCE), NULL);

// char array to hold the text from the textbox
char szInput[MAX_PATH];

// Obtains input from the textbox and puts it into the char array
GetWindowText(GetDlgItem(hwnd, 101), szInput, MAX_PATH);

Thanks everyone for your effort!
