D2D/GDI+ Interop Problem

I have recently read an article about Direct2D and GDI Interop from MSDN and I just wanted to make an attempt on that.

The problem with my code is that there is no (D2D) red rectangles at the output file but it does not produce any compile-time or runtime errors.

That really makes me frustrated as I have already spent my valuable weekend for that without any progress. Cry | :((

Any help is appreciated. Rose | [Rose]

Ref. article: Direct2D and GDI Interoperability Overview (Windows)[^]

Code block:

C++

#include<d2d1_2.h>
#include<gdiplus.h>
#include<iostream>
#include<wincodec.h>

#pragma comment(lib, "d2d1.lib")
#pragma comment(lib, "GdiPlus.lib")
#pragma comment(lib, "Windowscodecs.lib")

using namespace std;

void main()
{
	HRESULT hr;
	ID2D1Factory* factory;
	ID2D1DCRenderTarget* target;
	ID2D1SolidColorBrush* brush;

	D2D1CreateFactory(D2D1_FACTORY_TYPE_SINGLE_THREADED, &factory);

	// initialize GDI+
	ULONG_PTR token;
	Gdiplus::GdiplusStartup(&token, new Gdiplus::GdiplusStartupInput(), nullptr);


	auto image = new Gdiplus::Image(L"C:\\temp\\test.jpg");

	auto g = Gdiplus::Graphics::FromImage(image);

	auto prop = D2D1_RENDER_TARGET_PROPERTIES{
		D2D1_RENDER_TARGET_TYPE_HARDWARE ,
		D2D1_PIXEL_FORMAT{ DXGI_FORMAT_B8G8R8A8_UNORM , D2D1_ALPHA_MODE_PREMULTIPLIED },
		144.0f,
		144.0f,
		D2D1_RENDER_TARGET_USAGE_GDI_COMPATIBLE,
		D2D1_FEATURE_LEVEL_DEFAULT
	};


	hr = factory->CreateDCRenderTarget(&prop, &target);

	auto rect = RECT{ 0L,0L,800L, 600L };

	cout << boolalpha << (image == nullptr) << boolalpha << (g == nullptr) << endl;

	HDC deviceContext = g->GetHDC();

	// binds D2D device context to GDI+ device context.
	target->BindDC(deviceContext, &rect);

	// DrawRectangle using D2d
	target->BeginDraw();

	target->CreateSolidColorBrush(D2D1::ColorF(D2D1::ColorF::Red, 1.0f), &brush);
	target->DrawRectangle(D2D1_RECT_F{ 5.0f,5.0f,10.0f,10.0f }, brush);
	target->DrawRectangle(D2D1_RECT_F{ 10.0f,10.0f,30.0f,30.0f }, brush);

	hr = target->EndDraw();

	cout << boolalpha << SUCCEEDED(hr) << endl;

	CLSID pngEncoderClsId = { 0x557cf406, 0x1a04, 0x11d3,{ 0x9a,0x73,0x00,0x00,0xf8,0x1e,0xf3,0x2e } };

	// Transcode and save as PNG image file
	image->Save(L"C:\\temp\\output.png", &pngEncoderClsId);

	Gdiplus::GdiplusShutdown(token);
}

You are trying to do this in a console application. I do not think that will work since you have no Window to draw on. You need to create a Windows app to do it.

Direct3d Game programming error

Hi
I use the following link for starting an application with direct3d:
file:///D:/SoftwareProjects/Help/A%20Primer%20of%20DirectX%20Basics%20and%20the%20DirectX3D%20API%20-%20CodeProject.htm

I use this book too: Introduction to 3D Game Programming, written by Frank Luna

I use Microsoft Visual Studio 2012 C++ and Microsoft DirectX SDK (June 2010).

I have the following errors during debug of my application.

in the file DirectInput.cpp at the following lines:

HR(mKeyboard->Acquire());
HR(mMouse->Acquire());

The error is: one box appears with the following text:
Unexpected error encountered.
X Error
with buttons: YES/ NO

I don't know how to attach a screenshot of the error to the message.

Could you please help me to resolve the problem.

Also in DirectInput.h

I changed the declaration of the following:
extern DirectInput* gDInput;
in static DirectInput* gDInput;

Regards
