    Get user to input text

    I want to create a hang man game and need some way to have the user input text. Is there some function like MessageBox, but instead of outputting text you receive input, or do I have to make one myself.

    Thanks in advance.

    You most likely want an edit control, which will have to be in a window or dialog of some kind.

    If you aren't familiar with Windows programming this can be quite the challenge...

    You have to make one yourself. The function you want to write is called InputBox. It's not a standard function in C but surprisingly it is in other languages. Check out this code for ideas on how to implement it: C/C++ InputBox win32 implementation

    That is not a stand alone implementation, it is a wrapper on top of WIN32 (like MFC, which is direct from Microsoft and very well tested). It requires understanding of WIN32 apps to use.

    theForger's tutes are a much better starting point for what the OP wants.

    Here is the stand alone implementation that I use:

    Code:
    #include <windows.h>
    #include "resource.h"
    
    //Global variables
    int QueryLen;
    char *QueryCaption, *QueryText, *QueryDst;
    
    
    BOOL CALLBACK QueryDlgProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam) 
    {
    	switch (uMsg)
    	{
    	case WM_INITDIALOG:
    		{
    			SetWindowText(hwndDlg, QueryCaption);
    			SetDlgItemText(hwndDlg, IDC_QUERY_TEXT, QueryText);
    			SetDlgItemText(hwndDlg, IDC_QUERY_EDIT, QueryDst);
    			return TRUE;
    		}
    	case WM_COMMAND:
    		{
    			switch (LOWORD(wParam))
    			{
    			case IDOK:
    				{
    					GetWindowText(GetDlgItem(hwndDlg, IDC_QUERY_EDIT), QueryDst, QueryLen);
    					EndDialog(hwndDlg, IDOK);
    					return TRUE;
    				}
    			case IDCANCEL:
    				{
    					EndDialog(hwndDlg, IDCANCEL);
    					return TRUE;
    				}
    			}
    		}
    	}
    	return FALSE;
    }
    
    bool InputBox(char *caption, char *text, char *dst, int len)
    {
    	QueryCaption = caption;
    	QueryText = text;
    	QueryDst = dst;
    	QueryLen = len;
    	return (DialogBox(0, MAKEINTRESOURCE(IDD_DLG_QUERY), 0, QueryDlgProc) == IDOK);
    }
    This is the code for the dialog:
    Code:
    IDD_DLG_QUERY DIALOGEX 0, 0, 186, 90
    STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_CAPTION | 
        WS_SYSMENU
    CAPTION "Dialog"
    FONT 8, "MS Shell Dlg", 400, 0, 0x1
    BEGIN
        DEFPUSHBUTTON   "OK",IDOK,129,7,50,14
        PUSHBUTTON      "Cancel",IDCANCEL,129,24,50,14
        LTEXT           "Destination:",IDC_QUERY_TEXT,14,22,111,18
        EDITTEXT        IDC_QUERY_EDIT,15,52,155,15,ES_AUTOHSCROLL
    END
    And of course your resource.h should have:
    Code:
    #define IDD_DLG_QUERY                   1
    #define IDC_QUERY_TEXT                  1001
    #define IDC_QUERY_EDIT                  1002
    You can use the function like this:
    Code:
    char caption[MAX_PATH];
    strcpy(caption, "caption text");
    
    if (InputBox("Set Caption", "Title:", caption, sizeof(caption)))
    {
    	MessageBox(0, caption, caption, 0);
    }
