  • How would I set up this enum to return the image I want?

    - by Justen
    I'm trying to set up this enum so that it has the ability to return the correct image, though I'm struggling with a way to incorporate the context since it is in a separate class. public enum CubeType { GREEN { public Drawable getImage() { return Context.getResources().getDrawable( R.drawable.cube_green ); } }; abstract public Drawable getImage(); } The error I'm getting is: Cannot make a static reference to the non-static method getResources() from the type Context

  • MYSQL: how to search for fields that hold values sep. by commas?

    - by andufo
    hi. i have 2 tables: tags (id_tag,name) news (id,title,data,tags) The field newstags is a varchar(255). Im planning to put data like this in that field: "1,7,34" That means that a particular row in news is linked to tags 1, 7 and 34 from the tags table. Then, how can i search for ALL news records that have the 34 value (among others) in the tags field? Is there a better way to do this?

  • How do I get javascript-generated image maps to work with internet explorer?

    - by schwerwolf
    I'm using javascript to generate a high resolution grid for an image that I generated on a web server. The high-resolution grid is composed of a 'map' element with hundreds of 'area' child elements. Each 'area' element has onmouseover attribute that causes the display of a popup box. After assigning the map to the img (via the usemap attribute), Internet explorer ignores the 'onmouseover' attribute of the area elements that I added via javascript. The behavior is not caused by syntactical variations between IE and other browsers. A static map behaves correctly. Only the elements that I add dynamically to an existing image map fail to fire their corresponding mouse-over events. How can I get IE to fire the mouse-over event for the added 'area' elements? function generate_image_map ( img ) { var tile_width = 8; var tile_height = 10; var plotarea_left = 40; var plotarea_top = 45; var column_count = 100; var row_count = 120; var img_id = YAHOO.util.Dom.getAttribute(img, "id"); var img_map_id = YAHOO.util.Dom.getAttribute(img, "usemap"); var original_map = YAHOO.util.Selector.query(img_map_id)[0]; var area_nodes = YAHOO.util.Selector.query("area", original_map); var last_node = area_nodes[area_nodes.length - 1]; for (var y = 0; y < row_count; y++) { var top = Math.round(plotarea_top + (y * tile_height)); var bottom = Math.round(plotarea_top + (y * tile_height) + tile_height); for (var x = 0; x < column_count; x++) { var left = Math.round(plotarea_left + (x * tile_width)); var right = Math.round(plotarea_left + (x * tile_width) + tile_width); var area = document.createElement("area"); YAHOO.util.Dom.setAttribute(area, "shape", "rect"); YAHOO.util.Dom.setAttribute(area, "onmouseover", "alert('This does not appear in IE')" ); var coords = [ left, top, right, bottom ]; YAHOO.util.Dom.setAttribute(area, "coords", coords.join(",")); YAHOO.util.Dom.insertBefore(area, last_node); } } }

  • How can I use a PathGeometry as a mask for a BitmapSource (or any image data)?

    - by Jedidja
    Assuming I have a BitmapSource (actually I have access to the raw pixels as well if necessary), how can I use a PathGeometry as a mask to cut out certain parts of the image? 01234567890123456789 0 -------------------- 1 | + + | 2 | * | 3 | * ) | 4 | * | 5 | ( | 6 -------------------- Assuming I have a PathGeometry that describes a rectangle that goes from (0, 0) to (8, 3), I would like to be able to get one of the following two images: 01234567890123456789 0 -------------------- 1 | + | 2 | * | 3 | | 4 | | 5 | | 6 -------------------- or 012345678 0 --------- 1 | + | 2 | *| 3 ---------

  • How can I search on a list of values using Solr/Lucene?

    - by Mike
    Given the following query: (field:value1 OR field:value2 OR field:value3 OR ... OR field:value50) Can this be broken down into something less verbose? Basically I have hundreds of category IDs, and I need to search for items under large groups of category IDs (20-50 at a time). In MySQL, I'd just use field IN(value1, value2, value3) rather than (field = value1 OR field = value2 etc...). Is there a simpler way for Solr/Lucene?

  • How to change button's image in visual c++ at run time?

    - by karikari
    After trying and error for many times, I decided to ask here. My objective is I wanted to change the feature of my IE toolbar button. The button is firstly setup by IE at IE startup using the function CRebarHandler::onSetRedraw and CRebarHandler::setButtonMenu2(). And then, I create a call from another cpp file, to call CRebarHandler::setButtonMenu2(). I intent to change just the button's image. I assigned the ID of the image correctly. But somehow it does not work. When I put other code inside this function,like a code for writing to file, it is proven work. Means, it is properly being called from the other file. But the thing is, the code for the button inside CRebarHandler::setButtonMenu2() seems does not work. Need help. Here is the code I am working on (I modify John Lister's button code): LRESULT CRebarHandler::onSetRedraw(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled){ bHandled=false; if (m_ieVer==6){ if (!m_hWndToolbar) scanForToolbarSlow(); if (m_hWndToolbar){ findButton(m_hWndToolbar); if (m_buttonID>0) setButtonMenu(); } } return S_OK; } void CRebarHandler::setButtonMenu(){ HIMAGELIST hImageList = ImageList_Create(32, 32,ILC_COLOR16 | ILC_MASK,1, 0); HINSTANCE module = _AtlBaseModule.GetResourceInstance(); TBBUTTONINFO inf; inf.cbSize=sizeof(inf); inf.dwMask = TBIF_IMAGE; char psBuffer[128]; FILE *pPipe; float f = 0; pPipe = _popen("javaw -jar c:\\simmetrics.jar c:\\chtml.txt c:\\thtml.txt", "rt" ); char* p = fgets(psBuffer, 128, pPipe); std::istringstream iss(p); iss >> f; if (f > 0.9) { inf.iImage = 1; SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); iss.clear(); f = 0; } else { inf.iImage = 2; SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); iss.clear(); f = 0; } iss.clear(); f = 0; } void CRebarHandler::setButtonMenu2(){ TBBUTTONINFO inf; inf.cbSize=sizeof(inf); inf.dwMask = TBIF_IMAGE; inf.iImage = 1; //green SendMessage(NULL, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); }
