Здравствуйте, я просто пытаюсь сделать доску с каждой плиткой с полем в 5px, но даже при том, что в главном окне я предоставляю достаточно клиентской области, некоторые из дочерних элементов windows переполняются.

Я создаю дочерний элемент windows таким образом внутри LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
:
RECT rect;
//RECT clientRect;
HDC hdc;
static int iSelection = ID_BOARDSIZE_SMALL;
HMENU hMenu;
switch (message)
{
case WM_CREATE:
{
//Intiates with small checked
static HWND hWndChild[BIG_COUNT][BIG_COUNT];
hMenu = GetMenu(hWnd);
CheckMenuItem(hMenu, iSelection, MF_CHECKED);
hdc = GetDC(hWnd);
xClient = currentTileCount*(currentTileSize+10);
yClient = currentTileCount * (currentTileSize + 10);
SystemParametersInfo(SPI_GETWORKAREA, 0, &rect, 0);
int cxWork = (rect.left + rect.right + 1) / 2;
int cyWork = (rect.top + rect.bottom + 1) / 2;
MoveWindow(hWnd, cxWork - xClient/2, cyWork - yClient/2, xClient, yClient, TRUE);
//Creating Child Windows
for (int i = 0; i < currentTileCount; i++)
for (int j = 0; j < currentTileCount; j++)
{
hWndChild[i][j] = CreateWindow(szChildClass, NULL,
WS_CLIPCHILDREN|WS_CHILDWINDOW | WS_VISIBLE,
5+(currentTileSize+10)*i, 5 + (currentTileSize + 10)*j,
currentTileSize, currentTileSize, hWnd, NULL,
(HINSTANCE)GetWindowLong(hWnd,GWL_HINSTANCE), NULL);
}
ReleaseDC(hWnd, hdc);
}
break;
Я думаю, что мои вычисления для клиентской области и вычисления для определения местоположения каждой плитки правильные но как-то это переполняет, я довольно новичок в Windows API, поэтому, если этот вопрос носит элементарный характер, извините, мне кажется, что ребенок windows занимает больше места, чем ожидалось, и попытался найти то, что занимает это дополнительное место но не мог понять. Ждем ваших ответов спасибо
