C++ Simple Window Creation is executing java code for some reason? - c++

Question

I'm following the walkthrough of how to create a simple c++ application window here, and as far as I can tell my code is exactly the same as on the website. However whenever I try to execute the code it throws up this console where it seems to execute some java code and infinitely try to connect to a server. The problem is I have no earthly idea why this could be happening or what could be causing it. On cursory google searches it seems like it might be related to tesseract or some other package but I don't know why some outside package would ever be doing something in my code when I haven't included it. My project is a standard console app from Visual Studio but with my code replacing the default. I imagine this has nothing to do with the actual code but I have included it just in case.
#include <windows.h>
#include <stdio.h>
#include <tchar.h>
static TCHAR szWindowClass[] = _T("DesktopApp");
static TCHAR szTitle[] = _T("Windows Desktop Guided Tour Application");
HINSTANCE hInst;
LRESULT CALLBACK WndProc(_In_ HWND hWnd,_In_ UINT message,_In_ WPARAM wParam,_In_ LPARAM lParam) {
PAINTSTRUCT ps;
HDC hdc;
TCHAR greeting[] = _T("Hello, Windows desktop!");
switch (message){
case WM_PAINT:
hdc = BeginPaint(hWnd, &ps);
// Here your application is laid out.
// For this introduction, we just print out "Hello, Windows desktop!"
// in the top left corner.
TextOut(hdc,
5, 5,
greeting, _tcslen(greeting));
// End application specific layout section.
EndPaint(hWnd, &ps);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hWnd, message, wParam, lParam);
break;
}
return 0;
}
int WINAPI WinMain(_In_ HINSTANCE hInstance, _In_opt_ HINSTANCE hPrevInstance, _In_ LPSTR lpCmdLine, _In_ int nCmdShow) {
WNDCLASSEX wcex;
wcex.cbSize = sizeof(WNDCLASSEX);
wcex.style = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc = WndProc;
wcex.cbClsExtra = 0;
wcex.cbWndExtra = 0;
wcex.hInstance = hInstance;
wcex.hIcon = LoadIcon(wcex.hInstance, IDI_APPLICATION);
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
wcex.lpszMenuName = NULL;
wcex.lpszClassName = szWindowClass;
wcex.hIconSm = LoadIcon(wcex.hInstance, IDI_APPLICATION);
if (!RegisterClassEx(&wcex))
{
MessageBox(NULL,_T("Call to RegisterClassEx failed!"),_T("Windows Desktop Guided Tour"),NULL);
return 1;
}
// Store instance handle in our global variable
hInst = hInstance;
HWND hWnd = CreateWindowEx(
WS_EX_OVERLAPPEDWINDOW,
szWindowClass,
szTitle,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT,
500, 100,
NULL,
NULL,
hInstance,
NULL
);
if (!hWnd)
{
MessageBox(NULL,
_T("Call to CreateWindow failed!"),
_T("Windows Desktop Guided Tour"),
NULL);
return 1;
}
// The parameters to ShowWindow explained:
// hWnd: the value returned from CreateWindow
// nCmdShow: the fourth parameter from WinMain
ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);
// Main message loop:
MSG msg;
while (GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return (int)msg.wParam;
}

The cause of this was from a library by the name of Tesseract, I'm unsure why it was compiling with the code at all, but I can be sure that it was causing this, and a quick uninstall of the library fixed everything.
