  • Current tasks count at Appengine Task Queue

    - by splix
    Are there any ways to get count of current unfinished tasks at Google Appengine development server? I need it for making my integration test. I found a way to get this when running it local (just in mem), as described at appengine docs. But when i'm running it as a standalone server, from maven, this doesn't work. Just because library appengine-testing conflicts with Appengine SDK classes, and i can't use those classes together, when running sdk dev server.

  • GetAcceptExSockaddrs returns garbage! Does anyone know why?

    - by David
    Hello, I'm trying to write a quick/dirty echoserver in Delphi, but I notice that GetAcceptExSockaddrs seems to be writing to only the first 4 bytes of the structure I pass it. USES SysUtils; TYPE BOOL = LongBool; DWORD = Cardinal; LPDWORD = ^DWORD; short = SmallInt; ushort = Word; uint16 = Word; uint = Cardinal; ulong = Cardinal; SOCKET = uint; PVOID = Pointer; _HANDLE = DWORD; _in_addr = packed record s_addr : ulong; end; _sockaddr_in = packed record sin_family : short; sin_port : uint16; sin_addr : _in_addr; sin_zero : array[0..7] of Char; end; P_sockaddr_in = ^_sockaddr_in; _Overlapped = packed record Internal : Int64; Offset : Int64; hEvent : _HANDLE; end; LP_Overlapped = ^_Overlapped; IMPORTS function _AcceptEx (sListenSocket, sAcceptSocket : SOCKET; lpOutputBuffer : PVOID; dwReceiveDataLength, dwLocalAddressLength, dwRemoteAddressLength : DWORD; lpdwBytesReceived : LPDWORD; lpOverlapped : LP_OVERLAPPED) : BOOL; stdcall; external MSWinsock name 'AcceptEx'; procedure _GetAcceptExSockaddrs (lpOutputBuffer : PVOID; dwReceiveDataLength, dwLocalAddressLength, dwRemoteAddressLength : DWORD; LocalSockaddr : P_Sockaddr_in; LocalSockaddrLength : LPINT; RemoteSockaddr : P_Sockaddr_in; RemoteSockaddrLength : LPINT); stdcall; external MSWinsock name 'GetAcceptExSockaddrs'; CONST BufDataSize = 8192; BufAddrSize = SizeOf (_sockaddr_in) + 16; VAR ListenSock, AcceptSock : SOCKET; Addr, LocalAddr, RemoteAddr : _sockaddr_in; LocalAddrSize, RemoteAddrSize : INT; Buf : array[1..BufDataSize + BufAddrSize * 2] of Byte; BytesReceived : DWORD; Ov : _Overlapped; BEGIN //WSAStartup, create listen socket, bind to port 1066 on any interface, listen //Create event for overlapped (autoreset, initally not signalled) //Create accept socket if _AcceptEx (ListenSock, AcceptSock, @Buf, BufDataSize, BufAddrSize, BufAddrSize, @BytesReceived, @Ov) then WinCheck ('SetEvent', _SetEvent (Ov.hEvent)) else if GetLastError <> ERROR_IO_PENDING then WinCheck ('AcceptEx', GetLastError); {do WaitForMultipleObjects} _GetAcceptExSockaddrs (@Buf, BufDataSize, BufAddrSize, BufAddrSize, @LocalAddr, @LocalAddrSize, @RemoteAddr, @RemoteAddrSize); So if I run this, connect to it with Telnet (on same computer, connecting to localhost) and then type a key, WaitForMultipleObjects will unblock and GetAcceptExSockaddrs will run. But the result is garbage! RemoteAddr.sin_family = -13894 RemoteAddr.sin_port = 64 and the rest is zeroes. What gives? Thanks in advance!

  • Can we still develop Silverlight 2 applications

    - by TobyEvans
    Hi there, I've inherited a set of Silverlight 2 applications (new job), one of which needs upgrading. We can do the updates in code without problems, but the available dev machines all appear to be running Silverlight 3. I can't seem to find Silverlight 2 tools for download any more - is there a way to multi-target Silverlight the same way we can multi-target older versions of the main CLR? thanks Toby

  • WPF: Binding to ListBoxItem.IsSelected doesn't work for off-screen items

    - by Qwertie
    In my program I have a set of view-model objects to represent items in a ListBox (multi-select is allowed). The viewmodel has an IsSelected property that I would like to bind to the ListBox so that selection state is managed in the viewmodel rather than in the listbox itself. However, apparently the ListBox doesn't maintain bindings for most of the off-screen items, so in general the IsSelected property is not synchronized correctly. Here is some code that demonstrates the problem. First XAML: <StackPanel> <StackPanel Orientation="Horizontal"> <TextBlock>Number of selected items: </TextBlock> <TextBlock Text="{Binding NumItemsSelected}"/> </StackPanel> <ListBox ItemsSource="{Binding Items}" Height="200" SelectionMode="Extended"> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="IsSelected" Value="{Binding IsSelected}"/> </Style> </ListBox.ItemContainerStyle> </ListBox> <Button Name="TestSelectAll" Click="TestSelectAll_Click">Select all</Button> </StackPanel> C# Select All handler: private void TestSelectAll_Click(object sender, RoutedEventArgs e) { foreach (var item in _dataContext.Items) item.IsSelected = true; } C# viewmodel: public class TestItem : NPCHelper { TestDataContext _c; string _text; public TestItem(TestDataContext c, string text) { _c = c; _text = text; } public override string ToString() { return _text; } bool _isSelected; public bool IsSelected { get { return _isSelected; } set { _isSelected = value; FirePropertyChanged("IsSelected"); _c.FirePropertyChanged("NumItemsSelected"); } } } public class TestDataContext : NPCHelper { public TestDataContext() { for (int i = 0; i < 200; i++) _items.Add(new TestItem(this, i.ToString())); } ObservableCollection<TestItem> _items = new ObservableCollection<TestItem>(); public ObservableCollection<TestItem> Items { get { return _items; } } public int NumItemsSelected { get { return _items.Where(it => it.IsSelected).Count(); } } } public class NPCHelper : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public void FirePropertyChanged(string prop) { if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(prop)); } } Two separate problems can be observed. If you click the first item and then press Shift+End, all 200 items should be selected; however, the heading reports that only 21 items are selected. If you click "Select all" then all items are indeed selected. If you then click an item in the ListBox you would expect the other 199 items to be deselected, but this does not happen. Instead, only the items that are on the screen (and a few others) are deselected. All 199 items will not be deselected unless you first scroll through the list from beginning to end (and even then, oddly enough, it doesn't work if you perform scrolling with the little scroll box). My questions are: Can someone explain precisely why this occurs? Can I avoid or work around the problem?

  • Delay garbage collection?

    - by GeoffreyF67
    I'm using chrome (the dev version for my mac). I was looking at the timeline for my page loading and I saw that there is a 150ms delay due to some garbage collection taking place while loading the page. http://cl.ly/cce10619c698a5b276e2 It's the yellow line. I was curious if there's any way to stop this, delay it, whatever so I get the page to load faster? G-Man

  • GCC compiling a dll with __stdcall

    - by Chad
    When we compile a dll using __stdcall inside visual studio 2008 the compiled function names inside the dll are. FunctionName Though when we compile the same dll using GCC using wx-dev-cpp GCC appends the number of paramers the function has, so the name of the function using Dependency walker looks like. FunctionName@numberOfParameters or == FunctionName@8 How do you tell GCC compiler to remove @nn from exported symbols in the dll?

  • Lua for Wireshark: Tvp.new_real() doesn't exist?

    - by Jon Watte
    The documentation for Lua for Wireshark claims that the Tvp class has a new_real() method. However, this method seems to not exist when I try to use it in my Lua script. I'm using Wireshark 1.3.5 (latest dev version) for Windows x64. Did the method get renamed? If so, to what? Is there a better support forum for this particular question?

  • ios App Disclaimer

    - by Max
    I am writing an application for iPhone and had some questions regarding eula :- If I do not include any disclaimer/ eula in my app, then would Apple's standard EULA http://www.apple.com/legal/internet-services/itunes/appstore/dev/stdeula/ automatically apply to my app ? If I include a small disclaimer inside my application (as a popup on initial screen), then would Apple's EULA still cover my app ? I tried downloading few apps on my ipad and did not see Apple's standard EULA. So, where can I actually see the EULA before downloading something ?

  • How to XML escaping with Apache Velocity?

    - by Jan Algermissen
    I am generating XML using Apache Velocity. What is the best (most straight-forward) way to XML-escape the output? (I saw there is an escape tool, but could not figure out it's dev state. I also think that XML escaping is something that is very likely supported by Velocity directly.)

  • OpenGL texture misaligned on quad

    - by user308226
    I've been having trouble with this for a while now, and I haven't gotten any solutions that work yet. Here is the problem, and the specifics: I am loading a 256x256 uncompressed TGA into a simple OpenGL program that draws a quad on the screen, but when it shows up, it is shifted about two pixels to the left, with the cropped part appearing on the right side. It has been baffling me for the longest time, people have suggested clamping and such, but somehow I think my problem is probably something really simple, but I just can't figure out what it is! Here is a screenshot comparing the TGA (left) and how it appears running in the program (right) for clarity. Also take note that there's a tiny black pixel on the upper right corner, I'm hoping that's related to the same problem. Here's the code for the loader, I'm convinced that my problem lies in the way that I'm loading the texture. Thanks in advance to anyone who can fix my problem. bool TGA::LoadUncompressedTGA(char *filename,ifstream &texturestream) { cout << "G position status:" << texturestream.tellg() << endl; texturestream.read((char*)header, sizeof(header)); //read 6 bytes into the file to get the tga header width = (GLuint)header[1] * 256 + (GLuint)header[0]; //read and calculate width and save height = (GLuint)header[3] * 256 + (GLuint)header[2]; //read and calculate height and save bpp = (GLuint)header[4]; //read bpp and save cout << bpp << endl; if((width <= 0) || (height <= 0) || ((bpp != 24) && (bpp !=32))) //check to make sure the height, width, and bpp are valid { return false; } if(bpp == 24) { type = GL_RGB; } else { type = GL_RGBA; } imagesize = ((bpp/8) * width * height); //determine size in bytes of the image cout << imagesize << endl; imagedata = new GLubyte[imagesize]; //allocate memory for our imagedata variable texturestream.read((char*)imagedata,imagesize); //read according the the size of the image and save into imagedata for(GLuint cswap = 0; cswap < (GLuint)imagesize; cswap += (bpp/8)) //loop through and reverse the tga's BGR format to RGB { imagedata[cswap] ^= imagedata[cswap+2] ^= //1st Byte XOR 3rd Byte XOR 1st Byte XOR 3rd Byte imagedata[cswap] ^= imagedata[cswap+2]; } texturestream.close(); //close ifstream because we're done with it cout << "image loaded" << endl; glGenTextures(1, &texID); // Generate OpenGL texture IDs glBindTexture(GL_TEXTURE_2D, texID); glPixelStorei(GL_UNPACK_ALIGNMENT, 1); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); glTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE); glTexImage2D(GL_TEXTURE_2D, 0, type, width, height, 0, type, GL_UNSIGNED_BYTE, imagedata); delete imagedata; return true; } //Public loading function for TGA images. Opens TGA file and determines //its type, if any, then loads it and calls the appropriate function. //Returns: TRUE on success, FALSE on failure bool TGA::loadTGA(char *filename) { cout << width << endl; ifstream texturestream; texturestream.open(filename,ios::binary); texturestream.read((char*)header,sizeof(header)); //read 6 bytes into the file, its the header. //if it matches the uncompressed header's first 6 bytes, load it as uncompressed LoadUncompressedTGA(filename,texturestream); return true; }

  • Silverlight penetration rate

    - by sthg
    Duplicate of: Silverlight Install Base - How big is it? Hi, Anyone knows the penetration rate (in %) for all North-American internet users with the Silverlight plugin installed? Been looking all around, but couldn't find any comprehensive numbers. I'm looking for General Public penetration rates, not only within the dev community. Something close to Adobe's flash version penetration stats would be great.
