Typing stuff in GUI

I'm having trouble figuring how to type stuff in the actual GUI window. In console application it was cin but I have no idea how to do it in GUI.

Cout = print to the window

Cin = Get input from use

in console applications, the PDF file I posted tells us how but here is how in my words:

Print text:

I like to first do this at global scope:

UINT GetSizeOf (LPSTR Text)
{
for (int i = 0; i != -1; i++)
{
if (Text [i] == '\0')
{
return 0;
}
}
}

LPSTR Text [] = {
"Hello World";
};

UINT TextSize [] = {
GetSizeOf (Text [0])
};

Then I add this in my window procedure:

case WM_PAINT:
PAINTSTRUCT ps;
HDC hdc = BeginPaint (hwnd, &ps); // hwnd = Window handle so use what you used for that
TextOut (hdc, 10, 10, Text [0], TextSize [0]);
//10 = x coord to print to
//next 10 = y
//then we got the string to print out
//then we got the size of the string, I made a function to get the size for us (GetSizeOf)
EndPaint (hwnd, &ps);
break;

Now here is how you get input (You will need to read a lot to get this, it requires creating a new window:

Form1.h:

Code:: http://Form1.h
#define IDC_EDIT 2000
#define IDC_BUTTON 2005

typedef struct WindowsEventArguments
{
HWND hWnd;
WPARAM wParam;
LPARAM lParam;
HINSTANCE hIns;
}WndEventArgs, *lpWndEventArgs;

struct EVENTHANDLER
{
unsigned int Code;
long (*fnPtr)(lpWndEventArgs);
};

Main.cpp:

Code:: http://Main.cpp
#include <windows.h>
#include <tchar.h>
#include "Form1.h"
EVENTHANDLER EventHandler[3];

long fnWndProc_OnCreate(lpWndEventArgs Wea)
{
HWND hCtrl;

Wea->hIns=((LPCREATESTRUCT)Wea->lParam)->hInstance;
hCtrl=
CreateWindowEx(WS_EX_CLIENTEDGE,
"edit","",WS_CHILD|WS_VISIBLE,
10,30,270,30,
Wea->hWnd,
(HMENU)IDC_EDIT,
Wea->hIns,
0);
hCtrl = CreateWindow("button",
"Click Me",
WS_CHILD|WS_VISIBLE,
70,80,150,30,
Wea->hWnd,
(HMENU)IDC_BUTTON,
Wea->hIns,
0);

return 0;
}

long fnWndProc_OnCommand(lpWndEventArgs Wea)
{
switch(LOWORD(Wea->wParam))
{
case IDC_BUTTON:
{
TCHAR szBuffer[256];
GetWindowText(GetDlgItem(Wea->hWnd,IDC_EDIT),szBuffer,256);
MessageBox(Wea->hWnd,
szBuffer,
_T("Here Is The Text You Entered"),
MB_OK);
}
}

return 0;
}

long fnWndProc_OnClose(lpWndEventArgs Wea)
{
DestroyWindow(Wea->hWnd);
PostQuitMessage(0);
return 0;
}

void AttachEventHandlers(void)
{
EventHandler[0].Code=WM_CREATE;
EventHandler[0].fnPtr=fnWndProc_OnCreate;
EventHandler[1].Code=WM_COMMAND;
EventHandler[1].fnPtr=fnWndProc_OnCommand;
EventHandler[2].Code=WM_CLOSE;
EventHandler[2].fnPtr=fnWndProc_OnClose;
}

long __stdcall fnWndProc(HWND hwnd, unsigned int msg, WPARAM wParam,LPARAM lParam)
{
WndEventArgs Wea;

for(unsigned int i=0; i<3; i++)
{
if(EventHandler[i].Code==msg)
{
Wea.hWnd=hwnd, Wea.lParam=lParam, Wea.wParam=wParam;
return (*EventHandler[i].fnPtr)(&Wea);
}
}

return (DefWindowProc(hwnd, msg, wParam, lParam));
}

int __stdcall WinMain(HINSTANCE hIns, HINSTANCE hPrevIns, LPSTR lpszArgument, int iShow)
{
TCHAR szClassName[]=_T("Form1");
WNDCLASSEX wc;
MSG messages;
HWND hWnd;

AttachEventHandlers();
wc.lpszClassName=szClassName;
wc.lpfnWndProc=fnWndProc;
wc.cbSize=sizeof (WNDCLASSEX);
wc.style=CS_DBLCLKS;
wc.hIcon=LoadIcon(NULL,IDI_APPLICATION);
wc.hInstance=hIns;
wc.hIconSm=LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor=LoadCursor(NULL,IDC_ARROW);
wc.hbrBackground=(HBRUSH)COLOR_BTNSHADOW;
wc.cbWndExtra=0;
wc.cbClsExtra=0;
wc.lpszMenuName=NULL;
RegisterClassEx(&wc);
hWnd=CreateWindowEx(0,szClassName,_T("Enter Text In Text Box"),WS_OVERLAPPEDWINDOW,100,100,300,175,HWND_DESKTOP,0,hIns,0);
ShowWindow(hWnd,iShow);
while(GetMessage(&messages,NULL,0,0))
{
TranslateMessage(&messages);
DispatchMessage(&messages);
}

return messages.wParam;
}

I didn't make the input one.

lmao good luck, you WILL need it Very Happy
