  • After update, grub is broken.

    - by Bryan Allan
    Some months back I used wubi to install ubuntu on an hp laptop with vista. After not using it for a month or so, I loaded ubuntu and installed many updates (including kernel update). Windows boot manager loads without any problems, and I can boot to vista without problems. However, if I choose ubuntu, the screen briefly flashes Try (hd0,0) : NTFS5 and then goes to black. I never get to the kernel image selection screen.

  • Defining and selecting an area from an image

    - by meth0d_
    I want to create a game, where the world is loaded from an image file, much like Paradox Interactive does it for their games. If I have this image: Then the red, green, blue, cyan, magenta, white, black and grey should be different provinces. I know how to loop through them, and check if it's a new province, the problem is that I don't know how to define the region of the province for selection: I don't know how I can load in data, to make sure you can click anywhere on that province, and make sure it gets selected.

  • Why doesn't InkScape recognize the Ubuntu color palettes?

    - by Octavian Damiean
    InkScape 0.48.2 refuses to show my newly added Ubuntu color palettes in the color palettes selection menu. I have downloaded the Ubuntu color palettes for GIMP/InkScape from design.canonical.com, extracted the files and copied them to /usr/share/inkscape/palettes/ where all the other color palettes are. I've even made sure that all the files have the same rights, just in case. What am I missing?

  • Can't install NetBeans

    - by João Vinholi
    I had never had problems with netbeans installation, but now I am. I have downloaded JDK and JRE properly as I always do and I have started the installation using the terminal as well. When the screen for JDK directory selection comes, I select the JDK folder that I have downloaded, but for some reason the following warning is shown: "An error occurred while validating the path." Do you know what could be?

  • How to have an Arduino wait until it receives data over serial?

    - by SonicDH
    So I've wired up a little robot with a sound shield and some sensors. I'm trying to write a sketch that will let check the sensors. What I'd like for it to do is print out a little menu over serial, wait until the user sends a selection, jump to the function that matches their selection, then (once the function is done) jump back and print the menu again. Here's what I've written, but I'm not a that good of a coder, so it doesn't work. Where am I going wrong? #include <Servo.h> Servo steering; Servo throttle; int pos = 0; int val = 0; void setup(){   Serial.begin(9600);   throttle.write(90);   steering.write(90);   pinMode(A0, INPUT);   pinMode(7, INPUT);   char ch = 0; } void loop(){   Serial.println("Menu");   Serial.println("--------------------");   Serial.println("1. Motion Readout");   Serial.println("2. Distance Readout");   Serial.println("3. SD Directory Listing");   Serial.println("4. Sound Test");   Serial.println("5. Car Test");   Serial.println("--------------------");   Serial.println("Type the number and press enter");   while(char ch = 0){   ch = Serial.read();}   char ch;   switch(ch)   {     case '1':     motion();   }    ch = 0; } //menu over, lets get to work. void motion(){   Serial.println("Haha, it works!"); } I'm pretty sure a While loop is the right thing to do, but I'm probably implementing it wrong. Can anyone shed some light on this?

  • How can I render multiple windows with DirectX 9 in C++?

    - by Friso1990
    I'm trying to render multiple windows, using DirectX 9 and swap chains, but even though I create 2 windows, I only see the first one that I've created. My RendererDX9 header is this: #include <d3d9.h> #include <Windows.h> #include <vector> #include "RAT_Renderer.h" namespace RAT_ENGINE { class RAT_RendererDX9 : public RAT_Renderer { public: RAT_RendererDX9(); ~RAT_RendererDX9(); void Init(RAT_WindowManager* argWMan); void CleanUp(); void ShowWin(); private: LPDIRECT3D9 renderInterface; // Used to create the D3DDevice LPDIRECT3DDEVICE9 renderDevice; // Our rendering device LPDIRECT3DSWAPCHAIN9* swapChain; // Swapchain to make multi-window rendering possible WNDCLASSEX wc; std::vector<HWND> hwindows; void Render(int argI); }; } And my .cpp file is this: #include "RAT_RendererDX9.h" static LRESULT CALLBACK MsgProc( HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam ); namespace RAT_ENGINE { RAT_RendererDX9::RAT_RendererDX9() : renderInterface(NULL), renderDevice(NULL) { } RAT_RendererDX9::~RAT_RendererDX9() { } void RAT_RendererDX9::Init(RAT_WindowManager* argWMan) { wMan = argWMan; // Register the window class WNDCLASSEX windowClass = { sizeof( WNDCLASSEX ), CS_CLASSDC, MsgProc, 0, 0, GetModuleHandle( NULL ), NULL, NULL, NULL, NULL, "foo", NULL }; wc = windowClass; RegisterClassEx( &wc ); for (int i = 0; i< wMan->getWindows().size(); ++i) { HWND hWnd = CreateWindow( "foo", argWMan->getWindow(i)->getName().c_str(), WS_OVERLAPPEDWINDOW, argWMan->getWindow(i)->getX(), argWMan->getWindow(i)->getY(), argWMan->getWindow(i)->getWidth(), argWMan->getWindow(i)->getHeight(), NULL, NULL, wc.hInstance, NULL ); hwindows.push_back(hWnd); } // Create the D3D object, which is needed to create the D3DDevice. renderInterface = (LPDIRECT3D9)Direct3DCreate9( D3D_SDK_VERSION ); // Set up the structure used to create the D3DDevice. Most parameters are // zeroed out. We set Windowed to TRUE, since we want to do D3D in a // window, and then set the SwapEffect to "discard", which is the most // efficient method of presenting the back buffer to the display. And // we request a back buffer format that matches the current desktop display // format. D3DPRESENT_PARAMETERS deviceConfig; ZeroMemory( &deviceConfig, sizeof( deviceConfig ) ); deviceConfig.Windowed = TRUE; deviceConfig.SwapEffect = D3DSWAPEFFECT_DISCARD; deviceConfig.BackBufferFormat = D3DFMT_UNKNOWN; deviceConfig.BackBufferHeight = 1024; deviceConfig.BackBufferWidth = 768; deviceConfig.EnableAutoDepthStencil = TRUE; deviceConfig.AutoDepthStencilFormat = D3DFMT_D16; // Create the Direct3D device. Here we are using the default adapter (most // systems only have one, unless they have multiple graphics hardware cards // installed) and requesting the HAL (which is saying we want the hardware // device rather than a software one). Software vertex processing is // specified since we know it will work on all cards. On cards that support // hardware vertex processing, though, we would see a big performance gain // by specifying hardware vertex processing. renderInterface->CreateDevice( D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hwindows[0], D3DCREATE_SOFTWARE_VERTEXPROCESSING, &deviceConfig, &renderDevice ); this->swapChain = new LPDIRECT3DSWAPCHAIN9[wMan->getWindows().size()]; this->renderDevice->GetSwapChain(0, &swapChain[0]); for (int i = 0; i < wMan->getWindows().size(); ++i) { renderDevice->CreateAdditionalSwapChain(&deviceConfig, &swapChain[i]); } renderDevice->SetRenderState(D3DRS_CULLMODE, D3DCULL_CCW); // Set cullmode to counterclockwise culling to save resources renderDevice->SetRenderState(D3DRS_AMBIENT, 0xffffffff); // Turn on ambient lighting renderDevice->SetRenderState(D3DRS_ZENABLE, TRUE); // Turn on the zbuffer } void RAT_RendererDX9::CleanUp() { renderDevice->Release(); renderInterface->Release(); } void RAT_RendererDX9::Render(int argI) { // Clear the backbuffer to a blue color renderDevice->Clear( 0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB( 0, 0, 255 ), 1.0f, 0 ); LPDIRECT3DSURFACE9 backBuffer = NULL; // Set draw target this->swapChain[argI]->GetBackBuffer(0, D3DBACKBUFFER_TYPE_MONO, &backBuffer); this->renderDevice->SetRenderTarget(0, backBuffer); // Begin the scene renderDevice->BeginScene(); // End the scene renderDevice->EndScene(); swapChain[argI]->Present(NULL, NULL, hwindows[argI], NULL, 0); } void RAT_RendererDX9::ShowWin() { for (int i = 0; i < wMan->getWindows().size(); ++i) { ShowWindow( hwindows[i], SW_SHOWDEFAULT ); UpdateWindow( hwindows[i] ); // Enter the message loop MSG msg; while( GetMessage( &msg, NULL, 0, 0 ) ) { if (PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ) ) { TranslateMessage( &msg ); DispatchMessage( &msg ); } else { Render(i); } } } } } LRESULT CALLBACK MsgProc( HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam ) { switch( msg ) { case WM_DESTROY: //CleanUp(); PostQuitMessage( 0 ); return 0; case WM_PAINT: //Render(); ValidateRect( hWnd, NULL ); return 0; } return DefWindowProc( hWnd, msg, wParam, lParam ); } I've made a sample function to make multiple windows: void RunSample1() { //Create the window manager. RAT_ENGINE::RAT_WindowManager* wMan = new RAT_ENGINE::RAT_WindowManager(); //Create the render manager. RAT_ENGINE::RAT_RenderManager* rMan = new RAT_ENGINE::RAT_RenderManager(); //Create a window. //This is currently needed to initialize the render manager and create a renderer. wMan->CreateRATWindow("Sample 1 - 1", 10, 20, 640, 480); wMan->CreateRATWindow("Sample 1 - 2", 150, 100, 480, 640); //Initialize the render manager. rMan->Init(wMan); //Show the window. rMan->getRenderer()->ShowWin(); } How do I get the multiple windows to work?

  • Syntax error in Maya Python Script [on hold]

    - by Enchanter
    Ok this error is immensly frustrating as it is obviously a simple syntax issue. Basically I've written two lines of maya script in python designed to create a list of the names of all the joints of a model currently selected in the model viewer. Here are the two lines of script: import maya.cmds joints = ls(selection = true, type = 'joint') Upon compiling the code the script editor is saying there is a syntax error in the second line, but I do not see any reason why this code should not execute?

  • User Interface expected behavior

    - by Sn3akyP3t3
    I've encountered more than a few instances where a question arose from a desired change in a website page went against what I would describe as "expected behavior". One such recent request was to convert tab selection from what a tab typically does into a url redirect. I'm looking for guidance on where to turn to when these sorts of problems arise. Does the W3C cover these topics or are they left to the imagination of the web designer?
