Hello,
I create progressbar and process it WM_PAINT and it look fine. However on
the system that doesn't apply "visual styles" the progressbar seem have a
border. And paint does only inside that border.
How to remove that border ?

Could you show a picture ?
Have you checked if the control has border style (WS_BORDER)?

No, the control only have WS_CHILD or WS_VISIBLE style.
I uses CreateWindowExW with "msctls_progress32" class and WS_CHILD or
WS_VISIBLE style, Ex style = 0

preview :

here is the code

#include <windows.h>
#include "commctrl.h"

#pragma comment(lib,"comctl32.lib")

HWND pb1;
HINSTANCE g_hinst;

LRESULT CALLBACK WindowProc (HWND, UINT, WPARAM, LPARAM);

// **********
// Windows Main Function.
// - Here starts our demo program
int WINAPI WinMain ( HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow )
{
HWND hwnd;
MSG msg;

WNDCLASS wc;
g_hinst = hInstance;
wc.style = CS_HREDRAW|CS_VREDRAW;
wc.lpfnWndProc = WindowProc;
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 = L"test";

RegisterClass (&wc);

hwnd = CreateWindow (L"test",L"test",WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,
0,0,hInstance,0);

ShowWindow (hwnd,nCmdShow);
UpdateWindow (hwnd);

while (GetMessage(&msg,0,0,0))
{
TranslateMessage (&msg);
DispatchMessage (&msg);
}

return msg.wParam;
}

void * pb_old_proc;
LRESULT CALLBACK ProgressBarWindowProc
(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
if (message == WM_PAINT)
{
HBRUSH hbr = CreateSolidBrush(RGB(255, 0, 0));
PAINTSTRUCT ps;
HDC dc = BeginPaint(hwnd, &ps);
FillRect(dc, &ps.rcPaint, hbr);
DeleteObject(hbr);
return 0;
}
if (message == WM_ERASEBKGND) return 1;
return CallWindowProcW((WNDPROC)pb_old_proc, hwnd, message, wParam,
lParam);
}
// **********

LRESULT CALLBACK WindowProc

return 0;

EndPaint (hwnd,&ps);
return 0;
case WM_DESTROY:

return 0;
}
return DefWindowProc (hwnd,message,wParam,lParam);
}
