How to host win32 in wpf?
1. Create win32 Project
2. Modify project properties
Configuration TypeàDynamic Library(.dll)
Common Language Runtime Support àCommon Language Runtime Support(/clr)
Output DirectoryàDebug\
Intermidiate Directory->Debug\
3. Add clr。Must Finish previous step!
PresentationCore
PresentationFramework
WindowsBase
System
4. If vs2008,may be need to add lib
Error : fatal error LNK1104: cannot open file 'MSCOREE.lib'
Solution:Tools->Options->Projects and Solutions->VC++ Directories->Win32/Libraray filesà
add [C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib]
5. Insert Dialog,and modify dialog properties.
Contol->True
Style->Child
if no ,will error:host hwnd must by child window
Open Win32Project.cpp ,and add code:
namespace ManagedCpp
{
using namespace System;
using namespace System::Windows::Interop;
using namespace System::Runtime::InteropServices;
public ref class MyHwndHost : public HwndHost {
private:
HWND dialog;
protected:
virtual HandleRef BuildWindowCore(HandleRef hwndParent) override {
InitializeGlobals();
dialog = CreateDialog(hInstance,
MAKEINTRESOURCE(IDD_DIALOG1),
(HWND) hwndParent.Handle.ToPointer(),
(DLGPROC) About);
return HandleRef(this, IntPtr(dialog));
}
virtual void DestroyWindowCore(HandleRef hwnd) override {
// hwnd will be disposed for us
}
};
}
6. Modify Code:
**replace BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
With void InitializeGlobals()
Add:
bool initialized = false;
void InitializeGlobals() {
if (initialized) return;
initialized = true;
// TODO: Place code here.
MSG msg;
HACCEL hAccelTable;
// Initialize global strings
LoadString(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);
LoadString(hInstance, IDC_TYPICALWIN32DIALOG, szWindowClass, MAX_LOADSTRING);
MyRegisterClass(hInstance);
}
Remove:
BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
HWND hWnd;
hInst = hInstance; // Store instance handle in our global variable
hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);
if (!hWnd)
{
return FALSE;
}
ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);
return TRUE;
}
Replace _tWinMain with dllMain
Add:
#ifdef _MANAGED
#pragma managed(push, off)
#endif
HINSTANCE hInstance; // current instance
BOOL APIENTRY DllMain( HINSTANCE hInst,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
hInstance = hInst;
return TRUE;
}
#ifdef _MANAGED
#pragma managed(pop)
#endif
Remove:
int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
UNREFERENCED_PARAMETER(hPrevInstance);
UNREFERENCED_PARAMETER(lpCmdLine);
// TODO: Place code here.
MSG msg;
HACCEL hAccelTable;
// Initialize global strings
LoadString(hInstance, IDS_APP_TITLE, szTitle, MAX_LOADSTRING);
LoadString(hInstance, IDC_WIN32PROJECT, szWindowClass, MAX_LOADSTRING);
MyRegisterClass(hInstance);
// Perform application initialization:
if (!InitInstance (hInstance, nCmdShow))
{
return FALSE;
}
hAccelTable = LoadAccelerators(hInstance, MAKEINTRESOURCE(IDC_WIN32PROJECT));
// Main message loop:
while (GetMessage(&msg, NULL, 0, 0))
{
if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
return (int) msg.wParam;
}
Mayby have other error,please check it by youre self
Build successed ,continue!
7. Host in wpf
Create wpf application ,and add Reference
8. XAML, care namespace
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:my="clr-namespace:ManagedCpp;assembly=Win32Project"
Title="Window1" Height="310" Width="510">
<Grid>
<my:MyHwndHost Width="200" Height="200" />
</Grid>
</Window>
9. View:
Finish!
