フォームにテキスト ボックスがあり、ウィンドウの高さ/幅に合わせて設定したいと考えています。Cでこれを行う方法はありますか?明確にするために、これは C-Sharp (C#) ではなく C です。DevC++ を使用しています
TextBox を作成する必要があるコード:
HWND hwndText = CreateWindow(
TEXT("edit"),
TEXT(""),
WS_VISIBLE | WS_CHILD | WS_BORDER | WS_HSCROLL | WS_VSCROLL| ES_MULTILINE | ES_AUTOHSCROLL,
0,0,
630,470, //Height & Width
hwnd,
(HMENU)ID_MYTEXT,
hInstance,
NULL
);
完全なソース:
#include <windows.h>
const char g_szClassName[] = "myWindowClass";
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc;
HWND hwnd;
HMENU ID_MYTEXT;
MSG Msg;
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName = NULL;
wc.lpszClassName = g_szClassName;
wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
if(!RegisterClassEx(&wc))
{
MessageBox(NULL, "Window Registration Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
hwnd = CreateWindowEx(
WS_EX_CLIENTEDGE,
g_szClassName,
"Title",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, 640, 480,
NULL, NULL, hInstance, NULL
);
HWND hwndText = CreateWindow(
TEXT("edit"),
TEXT(""),
WS_VISIBLE | WS_CHILD | WS_BORDER | WS_HSCROLL | WS_VSCROLL| ES_MULTILINE | ES_AUTOHSCROLL,
0,0,
630,470,
hwnd,

NULL
);
if(hwnd == NULL)
{
MessageBox(NULL, "Window Creation Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
SendMessage(hwndText, WM_SETTEXT, 0, (LPARAM)"");
while(GetMessage(&Msg, NULL, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}
