meltedd / hvnc Goto Github PK

Everythin is working, except chrome

tested the hvnc, and its awesome! but i cant seem to launch edge. all the other browsers work fine except edge. please fix it if you can :)

This repo isnt being updated but just letting people know that im getting a black screen, if anyone else is getting this issue.

After one minute or when excuting start chrome, the screen changes to Dodger Blue.

Hi, Thanks a lot for such simple and beautiful code.

It works good in my local network in win7_x86 with DNS 127.0.0.1:6667 .
It also works well when I port forward using portmap.io with DNS like xxxxxxx.portmap.host:6667 and use my own pc as server and client.
It even works, when I use win7_x86 virtualbox as client.

But connection is slow, when using on Microsoft hypervisor.
But its still little faster than qwqdanchun/HVNC.

Do you have any advice on how do I make it fast ?
I don't care for video quality or pixels.

From my experience, when we decrease pixels, its file size decreases.
Also black n white images with colorful images have file size ratio of 2x:3x.
So black n white image is liter and fast.

The port is read from stdin, can you update your server\Main.cpp to support parsing port from command line arguments?

Anybody Explain The Steps How to Run This With all Steps include which files to compile super comfuse !!!

when u send it to another pc and open it its a big black window that if u close disconnects from server how to fix

processes dont spawn except for explorer, powershell, run, and those dont respond to clicks or keyboard inputs

edit: browsers actually do spawn but its unbelievably slow. and unable to be interacted with in any way

I am getting this error while building the server. Which packages should I install?

solved

I'm running hvnc on my windows server 2012 vds but I can't see the clients screen i just see a black screen

hey a tried compiling the server and client by using g++ with the g++ .cpp -o command and it gave me errors. Here are the logs

due to not free the DG on the function BitmapToJpg
fix it：

oid BitmapToJpg(HDC* hDc, HBITMAP* hbmpImage, int width, int height)
{
	ULONG_PTR gdiplusToken;
	GdiplusStartupInput gdiplusStartupInput;
	if (GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL) != Ok) {
		return;
	}
	Funcs::pSelectObject(*hDc, hbmpImage);
	Funcs::pBitBlt(*hDc, 0, 0, width, height, GetDC(0), 0, 0, SRCCOPY);
	
	IStream* jpegStream = NULL;
	if (CreateStreamOnHGlobal(NULL, TRUE, &jpegStream) != S_OK) {
		GdiplusShutdown(gdiplusToken);
		return;
	}


	Bitmap* image = Bitmap::FromHBITMAP(*hbmpImage, NULL);
	if (!image || image->GetLastStatus() != Ok) {
		jpegStream->Release(); 
		GdiplusShutdown(gdiplusToken); 
		delete image; 
		return;
	}


	if (image->Save(jpegStream, &jpegID, NULL) != Ok) {
		jpegStream->Release(); 
		delete image;
		GdiplusShutdown(gdiplusToken); 
		return;
	}

	delete image; 

	LARGE_INTEGER li = { 0 };
	jpegStream->Seek(li, STREAM_SEEK_SET, NULL);

	Bitmap* jpegImage = Bitmap::FromStream(jpegStream, FALSE);
	jpegStream->Release(); 

	if (!jpegImage || jpegImage->GetLastStatus() != Ok) {
		delete jpegImage; 
		GdiplusShutdown(gdiplusToken); 
		return;
	}

	HBITMAP compressedImage = NULL;
	jpegImage->GetHBITMAP(Color::White, &compressedImage);
	Funcs::pGetDIBits(*hDc, compressedImage, 0, height, g_pixels, (BITMAPINFO*)&g_bmpInfo, DIB_RGB_COLORS);
	delete jpegImage; 

	if (compressedImage) {
		DeleteObject(compressedImage);
	}
	
	GdiplusShutdown(gdiplusToken); 
}

.

Is this hvnc still undetectable by windows defender?

is normal ? to get this
i use Microsoft Visual Studio Professional 2019

Thanks for this modification.Stupid cheaters who steal people's code and make their business using this code.I hope their business will go to hell now.If you add some more options.I believe It will be more useful for people who are enthusiast.You can consider to add some options like.

1.start up Enable/Disable
2.Hidden execution mode/ no popup
3.Finally a builder where we can set port and dns / ip

And
Thanks for this nice works.

When I make the hvnc connection, the screen comes up. I can run brave etc applications, but in no way, my clicks and keyboard actions are not reflected on the client. There is only the screen.
