C2664 Cannot convert parameter 1 from 'int' to 'hwnd' - winapi

Question

Im trying to make a simple program for a old pocketpc application.
Want it to get the time and show it when i use the pushbutton.
With the code below, i get two compiler errors:
error C2664: 'SetWindowTextW' : cannot convert parameter 1 from 'int' to 'HWND' Line: 201
error C2664: 'CreateWindowExW' : cannot convert parameter 2 from 'const char [7]' to 'LPCWSTR' Line: 233
Ive tried to search, seems to be a common misunderstanding this, but i cant see an explanation that fits..
_strdate( dateStr);
SetWindowText(1003, dateStr);
Also this:
hwndLabel = CreateWindow("STATIC","Time",
WS_VISIBLE | WS_CHILD | SS_RIGHT,
10,200,75,35,hWnd,NULL,1003,NULL);
Edit:
After Xearinox suggestions, i get three new faults.
These:
error C2664: '_wstrdate' : cannot convert parameter 1 from 'char [9]' to 'wchar_t *' 199
error C2664: 'SetDlgItemTextW' : cannot convert parameter 3 from 'char [9]' to 'LPCWSTR' 201
error C2440: '=' : cannot convert from 'HWND' to 'int' 233
if i remove (HMENU) from the static, i get another last error:
error C2664: 'CreateWindowExW' : cannot convert parameter 10 from 'int' to 'HMENU' 233

Answer 1

First parameter of SetWindowText is hwnd, not control identifier.
Try this:
SetDlgItemTextW(hWnd, 1003, dateStr);
Use this for retrieve date:
WCHAR dateStr[256] = {0};
_wstrdate(dateStr);
Also use wide string parameters for CreateWindow:
hwndLabel = CreateWindowW(L"STATIC",L"Time",
WS_VISIBLE | WS_CHILD | SS_RIGHT,
10,200,75,35,hWnd, (HMENU)1003, NULL, NULL);
