• How to optimize calls to multiple APIs at once and return as one set?

  - by Martin

  I have a web app that searches across 2 APIs right now. I have my own Restful web service that I call, and it does all the work on the backend to asynchronously call the 2 APIs and concatenate them into one result set for my web app to use. I want to scale this out and add as many other APIs as I can (currently looking at about 10 more). But as I add APIs, the call to my service gets (potentially) slower and more complex. How do I handle one API not responding ... and other issues that arise? What would be the best way to approach this? Should I create a service call for each API, that way each one is independent and not coupled to all the other calls? Is there a way on the backend to handle the multiple API calls without all the extra complexity it adds? If I go the route of a service call per API, now my client code gets more complex (and I have a lot of clients)? And it's more work for the client, and since I have mobile apps, it will cost the client more data usage. If I go one service call, is there a way to set up some sort of connection so I can return data as I get it, in case one service call hangs?

• What's the right/standard way of achieving separation of concerns?

  - by Ghanima

  Some background: I want to start developing games, and taking some of the advice given in this site, I've started with something simple and familiar, such as pong, tetris, etc. I want to take as much time as needed to make sure that I have the basics right before moving on to something bigger. I have medium programming experience but I realize making games is a different thing. I find myself wondering many things like should this be in a separate class? Should this module handle this stuff or is it better to let other modules have that kind of functionality? For example, the bouncing of a ball in pong, right now is handled in the ball module, but maybe it's better that some other module did it. Right now I have different modules: one for the graphics, one for the game logic, and others for the objects (depending on the kind of movement required, not all the objects are alike). I know I am asking a lot, any tips you have will be very much appreciated. Short question: What's the right or standard way of separating the modules? What have you found most effective? Is it enough to just keep the drawing (graphics) and the logic separate? Is it necessary to have a lot of classes? (for example for the objects in the game, to handle the movement, etc)

• Designing communications for extensibility

  - by Thomas S.

  I am working on the design stages of an application that will a) collect data from various sources (in my case that's scientific data from serial ports), keeping track of the age of the data, b) generate real-time statistics (e.g. running averages) c) display, record, and otherwise handle the data (and statistics). I anticipate that I will be adding both data producers and consumers over time, and would like to design this application abstractly so that I will be able to trivially add functionality with a small amount of interface code. What I'm stumbling on is deciding what communication infrastructure I should use to handle the interfaces. In particular, how should I make the processed data and statistics available to multiple consumers? Some things I've considered: Writing to several named pipes (variable number). Each consumer reads from one of them. Using FUSE to make a userspace filesystem where a read() returns the latest line of data even if another process has already read it. Making a TCP server, and having consumers connect and request data individually. Simply writing the consumers as part of the same program that aggregates the data. So I would like to hear your all's advice on deciding how to interface these functions in the best way to keep them separate and allow room for extenstions.

• 2D Tile Collision free movement

  - by andrepcg

  I'm coding a 3D game for a project using OpenGL and I'm trying to do tile collision on a surface. The surface plane is split into a grid of 64x64 pixels and I can simply check if the (x,y) tile is empty or not. Besides having a grid for collision, there's still free movement inside a tile. For each entity, in the end of the update function I simply increase the position by the velocity: pos.x += v.x; pos.y += v.y; I already have a collision grid created but my collide function is not great, i'm not sure how to handle it. I can check if the collision occurs but the way I handle is terrible. int leftTile = repelBox.x / grid->cellSize; int topTile = repelBox.y / grid->cellSize; int rightTile = (repelBox.x + repelBox.w) / grid->cellSize; int bottomTile = (repelBox.y + repelBox.h) / grid->cellSize; for (int y = topTile; y <= bottomTile; ++y) { for (int x = leftTile; x <= rightTile; ++x) { if (grid->getCell(x, y) == BLOCKED){ Rect colBox = grid->getCellRectXY(x, y); Rect xAxis = Rect(pos.x - 20 / 2.0f, pos.y - 20 / 4.0f, 20, 10); Rect yAxis = Rect(pos.x - 20 / 4.0f, pos.y - 20 / 2.0f, 10, 20); if (colBox.Intersects(xAxis)) v.x *= -1; if (colBox.Intersects(yAxis)) v.y *= -1; } } } If instead of reversing the direction I set it to false then when the entity tries to get away from the wall it's still intersecting the tile and gets stuck on that position. EDIT: I've worked with Flashpunk and it has a great function for movement and collision called moveBy. Are there any simplified implementations out there so I can check them out?

• Game engine lib and editor

  - by luke

  I would like to know the best way/best practice to handle the following situation. Suppose the project you are working on is split in two sub-projects: game engine lib editor gui. Now, you have a method bool Method( const MethodParams &params ) that will be called during game-level initialization. So it is a method belonging to the game engine lib. Now, the parameters of this method, passed as a reference the structure MethodParams can be decided via the editor, in the level design phase. Suppose the structure is the following: enum Enum1 { E1_VAL1, E1_VAL2, }; enum Enum2 { E2_VAL1, E2_VAL2, E2_VAL3, }; struct MethodParams { float value; Enum1 e1; Enum2 e2; // some other member } The editor should present a dialog that will let the user set the MethodParams struct. A text control for the field value. Furthermore, the editor needs to let the user set the fields e1 and e2 using, for example, two combo boxes (a combo box is a window control that has a list of choices). Obviously, every enum should be mapped to a string, so the user can make an informed selection (i have used E1_VAL1 etc.., but normally the enum would be more meaningful). One could even want to map every enum to a string more informative (E1_VAL1 to "Image union algorithm", E1_VAL2 to "Image intersection algorithm" and so on...). The editor will include all the relevant game egine lib files (.h etc...), but this mapping is not automatic and i am confused on how to handle it in a way that, if in future i add E1_VAL3 and E1_VAL4, the code change will be minimal.

• How to control messages to the same port from different emitters?

  - by Alex In Paris

  Scene: A company has many factories X, each emits a message to the same receive port in a Biztalk server Y; if all messages are processed without much delay, each will trigger an outgoing message to another system Z. Problem: Sometimes a factory loses its connection for a half-day or more and, when the connection is reestablished, thousands of messages get emitted. Now, the messages still get processed well by Y (Biztalk can easily handle the load) but system Z can't handle the flood and may lock up and severely delay the processing of all other messages from the other X. What is the solution? Creating multiple receive locations that permits us to pause one X or another would lose us information if the factory isn't smart enough to know whether the message was received or not. What is the basic pattern to apply in Biztalk for this problem? Would some throttling parameters help to limit the flow from any one X? Or are their techniques on the end part of Y which I should use instead ? I would prefer this last one since I can be confident that the message box will remember any failures, which could then be resumed.

• How should VertexBuffers be used with Multiple Monitors in DirectX 9

  - by Joshua C

  I am currently using DirectX 9 on a machine with two GPUs and three monitors. I am currently trying to draw a triangle on each monitor using vertexbuffers; A directx helloworld with multiple monitors if you will. I am familiar with some DirectX coding, but new to multiple monitor DirectX coding. I may be going about this the wrong way, so please do correct me if I'm doing something wrong. I have created a Direct3D Device for each enumerated adapter sharing the same Form handle. This allows me to successfully use all three monitors in full-screen mode. For Each Adapter In Direct3D.Adapters Dim PresentParameters As New PresentParameters 'Setup PresentParameters PresentParameters.Windowed = False PresentParameters.DeviceWindowHandle = MainForm.Handle Dim Device as New Device(Direct3D, Adapter.Adapter, DeviceType.Hardware, PresentParameters.DeviceWindowHandle, CreateFlags.HardwareVertexProcessing, PresentParameters) Device.SetRenderState(RenderState.Lighting, False) Devices.Add(Device) Next I can also draw text to each device successfully using a different Font for each Device. When I render a triangle using a different VertexBuffer for each Device, only two monitors display the triangle. One of the two monitors on the same GPU, and the monitor on it's own GPU display properly. VertexBuffer = New VertexBuffer(Device, 4 * Marshal.SizeOf(GetType(ColoredVertex)), Usage.WriteOnly, VertexFormat.None, Pool.Managed) Dim Verts = VertexBuffer.Lock(0, 0, LockFlags.None) Verts.WriteRange({ New ColoredVertex(-.5, -.5, 1, ForeColor), New ColoredVertex(0, .5, 1, ForeColor), New ColoredVertex(.5, -.5, 1, ForeColor) }) VertexBuffer.Unlock() VertexDeclaration = New VertexDeclaration(Device, { New VertexElement(0, 0, DeclarationType.Float3, DeclarationMethod.Default, DeclarationUsage.Position, 0), New VertexElement(0, 12, DeclarationType.Color, DeclarationMethod.Default, DeclarationUsage.Color, 0), VertexElement.VertexDeclarationEnd }) Render Code: Device.SetStreamSource(0, VertexBuffer, 0, Marshal.SizeOf(GetType(ColoredVertex))) Device.VertexDeclaration = VertexDeclaration Device.DrawPrimitives(PrimitiveType.TriangleList, 0, 1) I have to assume the fact that they share the same physical card comes into play. Should I use multiple buffers on the same card, and if so, how? Or what is the way I should access the VertexBuffer across Devices? Another thought I had was the non working monitor acts like there are no lights. Is turning off lighting on each device on the same card causing issues somehow?

• kSOAP2 and SOAPAction on Android

  - by Matze

  Hi everyone, I am trying to access a Webservice with kSOAP2 on an Android Phone. I think the connection is being established, but the server won't answer my request since I'm not providing a SOAP Action Header which seems to be required in SOAP Version 1.1(please correct me if I'm wrong here) which I have to use since the server does not support Version 1.2 . The concrete Faultcode which is returning in the request looks like this: faultactor null faultcode "S:Server" (id=830064966432) faultstring "String index out of range: -11" (id=830064966736) The errorcode which is generated on the server (I'm running it on a localhost) looks like this: 4.05.2010 20:20:29 com.sun.xml.internal.ws.transport.http.HttpAdapter fixQuotesAroundSoapAction WARNUNG: Received WS-I BP non-conformant Unquoted SoapAction HTTP header: http://server.contextlayer.bscwi.de/createContext 24.05.2010 20:20:29 com.sun.xml.internal.ws.server.sei.EndpointMethodHandler invoke SCHWERWIEGEND: String index out of range: -11 java.lang.StringIndexOutOfBoundsException: String index out of range: -11 at java.lang.String.substring(Unknown Source) at de.bscwi.contextlayer.xml.XmlValidator.isValid(XmlValidator.java:41) at de.bscwi.contextlayer.server.ContextWS.createContext(ContextWS.java:45) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.sun.xml.internal.ws.api.server.InstanceResolver$1.invoke(Unknown Source) at com.sun.xml.internal.ws.server.InvokerTube$2.invoke(Unknown Source) at com.sun.xml.internal.ws.server.sei.EndpointMethodHandler.invoke(Unknown Source) at com.sun.xml.internal.ws.server.sei.SEIInvokerTube.processRequest(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.__doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber._doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.doRun(Unknown Source) at com.sun.xml.internal.ws.api.pipe.Fiber.runSync(Unknown Source) at com.sun.xml.internal.ws.server.WSEndpointImpl$2.process(Unknown Source) at com.sun.xml.internal.ws.transport.http.HttpAdapter$HttpToolkit.handle(Unknown Source) at com.sun.xml.internal.ws.transport.http.HttpAdapter.handle(Unknown Source) at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handleExchange(Unknown Source) at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handle(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.AuthFilter.doFilter(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.ServerImpl$Exchange$LinkHandler.handle(Unknown Source) at com.sun.net.httpserver.Filter$Chain.doFilter(Unknown Source) at sun.net.httpserver.ServerImpl$Exchange.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) The relevant part of the WSDL (at least that's what I'm thinking) looks like this: <operation name="createContext"> <soap:operation soapAction=""/> - <input> <soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> </input> - <output> <soap:body use="literal" namespace="http://server.contextlayer.bscwi.de/"/> </output> </operation> In my code I'm adding a Header, but it seems like I'm doing it wrong: private static final String SOAP_ACTION = ""; //... SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope (SoapEnvelope.VER11); soapEnvelope.setOutputSoapObject(Request); AndroidHttpTransport aht = new AndroidHttpTransport (URL); //... aht.call(SOAP_ACTION, soapEnvelope); SoapPrimitive resultString = (SoapPrimitive) soapEnvelope.getResponse(); Any advice would be great since I'm running out of ideas.. Thanks folks!

• JSF: Cannot catch ViewExpiredException

  - by ifischer

  I'm developing a JSF 2.0 application on Glassfish v3 and i'm trying to handle the ViewExpiredException. But whatever i do, i always get a Glassfish error report instead of my own error page. To simulate the occurrence of the VEE, i inserted the following function into my backing bean, which fires the VEE. I'm triggering this function from my JSF page through a commandLink. The Code: @Named public class PersonHome { (...) public void throwVEE() { throw new ViewExpiredException(); } } At first i tried it by simply adding an error-page to my web.xml: <error-page> <exception-type>javax.faces.application.ViewExpiredException</exception-type> <location>/error.xhtml</location> </error-page> But this doesn't work, i'm not redirected to error but i'm shown the Glassfish errorpage, which shows a HTTP Status 500 page with the following content: description:The server encountered an internal error () that prevented it from fulfilling this request. exception: javax.servlet.ServletException: javax.faces.application.ViewExpiredException root cause: javax.faces.el.EvaluationException:javax.faces.application.ViewExpiredException root cause:javax.faces.application.ViewExpiredException Next thing i tried was to write ExceptionHandlerFactory and a CustomExceptionHandler, as described in JavaServerFaces 2.0 - The Complete Reference. So i inserted the following tag into faces-config.xml: <factory> <exception-handler-factory> exceptions.ExceptionHandlerFactory </exception-handler-factory> </factory> And added these classes: The factory: package exceptions; import javax.faces.context.ExceptionHandler; public class ExceptionHandlerFactory extends javax.faces.context.ExceptionHandlerFactory { private javax.faces.context.ExceptionHandlerFactory parent; public ExceptionHandlerFactory(javax.faces.context.ExceptionHandlerFactory parent) { this.parent = parent; } @Override public ExceptionHandler getExceptionHandler() { ExceptionHandler result = parent.getExceptionHandler(); result = new CustomExceptionHandler(result); return result; } } The custom exception handler: package exceptions; import java.util.Iterator; import javax.faces.FacesException; import javax.faces.application.NavigationHandler; import javax.faces.application.ViewExpiredException; import javax.faces.context.ExceptionHandler; import javax.faces.context.ExceptionHandlerWrapper; import javax.faces.context.FacesContext; import javax.faces.event.ExceptionQueuedEvent; import javax.faces.event.ExceptionQueuedEventContext; class CustomExceptionHandler extends ExceptionHandlerWrapper { private ExceptionHandler parent; public CustomExceptionHandler(ExceptionHandler parent) { this.parent = parent; } @Override public ExceptionHandler getWrapped() { return this.parent; } @Override public void handle() throws FacesException { for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) { ExceptionQueuedEvent event = i.next(); System.out.println("Iterating over ExceptionQueuedEvents. Current:" + event.toString()); ExceptionQueuedEventContext context = (ExceptionQueuedEventContext) event.getSource(); Throwable t = context.getException(); if (t instanceof ViewExpiredException) { ViewExpiredException vee = (ViewExpiredException) t; FacesContext fc = FacesContext.getCurrentInstance(); NavigationHandler nav = fc.getApplication().getNavigationHandler(); try { // Push some useful stuff to the flash scope for // use in the page fc.getExternalContext().getFlash().put("expiredViewId", vee.getViewId()); nav.handleNavigation(fc, null, "/login?faces-redirect=true"); fc.renderResponse(); } finally { i.remove(); } } } // At this point, the queue will not contain any ViewExpiredEvents. // Therefore, let the parent handle them. getWrapped().handle(); } } But STILL i'm NOT redirected to my error page - i'm getting the same HTTP 500 error like above. What am i doing wrong, what could be missing in my implementation so that the exception is handled correctly?

• c# SendMessage and Skype woes

  - by Xcelled194

  I'm trying to create an add-on to Skype with C#. I don't want to use Skype4COM, as I'd like the experience with messages and such. Unfortunately, the messages are tripping me up. I've got the pumps and such set up. They all work, and my app successfully sends the "APIDiscover" message to Skype, gets a "PendingAuth" response and then the "AttachSuccess" message. However, when I try to send "ping" to Skype (to which it should reply "pong") nothing happens. The return code from SendMessage is 0 but Marshall.GetLastWin32Error is 1400 (Invalid handle). The handle was returned with the AttachSuccess method. The equivalent C++ code does work, so I'm at a loss. First is the C++ code I'm using as a guide: Here's the (cut down) message pump. You can ignore everything but where I put the //<---- static LRESULT APIENTRY SkypeAPITest_Windows_WindowProc( HWND hWindow, UINT uiMessage, WPARAM uiParam, LPARAM ulParam) { LRESULT lReturnCode; bool fIssueDefProc; lReturnCode=0; fIssueDefProc=false; switch(uiMessage) { case WM_COPYDATA: if( hGlobal_SkypeAPIWindowHandle==(HWND)uiParam ) { PCOPYDATASTRUCT poCopyData=(PCOPYDATASTRUCT)ulParam; printf( "Message from Skype(%u): %.*s\n", poCopyData->dwData, poCopyData->cbData, poCopyData->lpData); lReturnCode=1; } break; default: if( uiMessage==uiGlobal_MsgID_SkypeControlAPIAttach ) { switch(ulParam) { case SKYPECONTROLAPI_ATTACH_SUCCESS: printf("!!! Connected; to terminate issue #disconnect\n"); hGlobal_SkypeAPIWindowHandle=(HWND)uiParam;//<---- Right here is where we receive the handle from Skype. break; } if( fIssueDefProc ) lReturnCode=DefWindowProc( hWindow, uiMessage, uiParam, ulParam); return(lReturnCode); } and this is the (again dumbed down) "sending message" code void __cdecl Global_InputProcessingThread(void *) { static char acInputRow[1024]; bool fProcessed; if( SendMessageTimeout( HWND_BROADCAST, uiGlobal_MsgID_SkypeControlAPIDiscover, (WPARAM)hInit_MainWindowHandle, 0, SMTO_ABORTIFHUNG, 1000, NULL)!=0 ) { while(Global_Console_ReadRow( acInputRow, sizeof(acInputRow)-1)) { if( fProcessed==false && hGlobal_SkypeAPIWindowHandle!=NULL ) { COPYDATASTRUCT oCopyData; // send command to skype oCopyData.dwData=0; oCopyData.lpData=acInputRow; oCopyData.cbData=strlen(acInputRow)+1; if( oCopyData.cbData!=1 ) { if( SendMessage( hGlobal_SkypeAPIWindowHandle, WM_COPYDATA, (WPARAM)hInit_MainWindowHandle, (LPARAM)&oCopyData)==FALSE ) { hGlobal_SkypeAPIWindowHandle=NULL; printf("!!! Disconnected\n"); } } } } } SendMessage( hInit_MainWindowHandle, WM_CLOSE, 0, 0); SetEvent(hGlobal_ThreadShutdownEvent); fGlobal_ThreadRunning=false; } And now here's my C# public bool PreFilterMessage(ref Message m) { Console.WriteLine(m.ToString()); if (m.Msg == WM_COPYDATA && SkypeAPIWindowHandle == m.WParam) { SkypeMessage(m); return true; } if (m.Msg == MsgApiAttach) { switch (m.LParam.ToInt32()) { case (int)SkypeControlAPIAttach.SUCCESS: SkypeAPIWindowHandle = m.WParam; //Here's where we set the Skype Handle AttachSuccess(m); return true; } } return false; //Defer all other messages } And here is my DLL import and Sending code [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = false)] static extern IntPtr SendMessageA(IntPtr hWnd, UInt32 Msg, IntPtr wParam, ref MsgHelper.COPYDATASTRUCT lParam); public static void Command(string c) { if (c.Last() != '\0') c += "\0"; //Make string null terminated Console.WriteLine(); MsgHelper.COPYDATASTRUCT cda = new MsgHelper.COPYDATASTRUCT(); cda.dwData = new IntPtr(0); cda.lpData = c; cda.cbData = c.Length + 1; Marshal.GetLastWin32Error(); //Clear last error Console.WriteLine(SendMessageA(mHelper.SkypeAPIWindowHandle, MsgHelper.WM_COPYDATA, IntPtr.Zero, ref cda)); Console.WriteLine(Marshal.GetLastWin32Error()); } COPYDATASTRUCT is: public struct COPYDATASTRUCT { public IntPtr dwData; public int cbData; [MarshalAs(UnmanagedType.LPStr)] public string lpData; } I think that's everything. Let me know if I forgot something. Any ideas why I'm getting the 1400?

• Issue with Silverlight interop with JBoss WebService

  - by Hadi Eskandari

  I have a simple JAXWS webservice deployed in JBoss. It runs fine with a java client but I'm trying to connect using a Silverlight 3.0 application. I've changed the webservice to use Soap 1.1: @BindingType(value = "http://schemas.xmlsoap.org/wsdl/soap/http") public class UserSessionBean implements UserSessionRemote { ... } I'm using BasicHttpBinding on the Silverlight client. There are two issues: 1- When I connect from VisualStudio (2008 and 2010) to create the webservice proxies, the following exception is thrown, but the proxy is generated successfully. This also happens when I try to update the existing web service reference (but it also updates fine). com.sun.xml.ws.server.UnsupportedMediaException: Unsupported Content-Type: application/soap+xml; charset=utf-8 Supported ones are: [text/xml] at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:291) at com.sun.xml.ws.encoding.StreamSOAPCodec.decode(StreamSOAPCodec.java:128) at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:287) at com.sun.xml.ws.transport.http.HttpAdapter.decodePacket(HttpAdapter.java:276) at com.sun.xml.ws.transport.http.HttpAdapter.access$500(HttpAdapter.java:93) at com.sun.xml.ws.transport.http.HttpAdapter$HttpToolkit.handle(HttpAdapter.java:432) at com.sun.xml.ws.transport.http.HttpAdapter.handle(HttpAdapter.java:244) at com.sun.xml.ws.transport.http.servlet.ServletAdapter.handle(ServletAdapter.java:135) at org.jboss.wsf.stack.metro.RequestHandlerImpl.doPost(RequestHandlerImpl.java:225) at org.jboss.wsf.stack.metro.RequestHandlerImpl.handleHttpRequest(RequestHandlerImpl.java:82) at org.jboss.wsf.common.servlet.AbstractEndpointServlet.service(AbstractEndpointServlet.java:85) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:182) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Thread.java:619) 2- When I use the proxy to fetch some data from the webservice (even methods with primitive types), I get the following error on Silverlight client: "An error occurred while trying to make a request to URI 'http://localhost:9090/admintool/UserSessionEJB'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details." Setting a breakpoint on my java code, I can see that it is not hit when I run the silverlight client, so it is probably a cross domain issue, but I'm not sure how to handle it (I've already created a crossdomain.xml file and put it beside my HTML page hosting the silverlight client). I appreciate any help!

• I finished coding my program. What's next? what are the steps I should take that would enable me to

  - by Luay

  Hi, I finished developing a program and would like to sell it online. However, I am not really sure of what to do next. Here is my current plan (in-order): 1- Add a 'deployment' project (i'm using visual studio) to my project so I can create a setup file for my program. 2- Use visual studio 'testing' add ons to test the program. I have no idea how to do it, but will teach myself. 3- When all is done, install the program on my wife's, parents and in-laws computer to further test it under different environments. 3- Setup a small Ltd. company. ( I might start this earlier as it might take a few weeks to complete). 4- Build / finish building a website (actually I started on this step a few weeks ago but haven't devoted enough time for it to complete yet). 5- Find a software / service to protect my program from piracy. I know it is impossible to protect the program from piracy. I understand that fully. But I still want to implement some sort of solution that wouldn't harm or deter honest customers. 6- Set up a business paypal account. 7- Find a software / service to handle payments on my website 8- Find a software / service to handle issuing license codes 9- Set up all of the above and go 'live'. However, I have zero experience in this sort of thing and would like your guidance on some points. 1- Is it necessary to setup a company? Can I sell as an individual? Will selling as an individual deter persons or companies from buying my software? 2- What is a decent choice for as a software / service to protect my program from my piracy. I have done a quick search and found something called Quick License Manager by Interactive Studios. Is this the sort of thing I am looking for? Is it any good? At which stage do I use or implement their service (or any similar service you might point me too? I guess I am really asking: how does this work? Would they give me a file I just add to my project, rebuild it and that's it? 3- What should I implement to handle payments online and how complicated is it? could you point me to any such services, please? 4- What should I implement to handle issuing license codes and how will that software / service coordinate with the software / service that handles the anti-piracy stuff? could you point me to such services, please? 5- In a different Stack Overflow question (by another user) someone suggested a cms system called Software Droid (http://www.softwaredroid.com). Is this what I am after. Will it help? 6- If the steps i'm following are incorrect in order or logic could you please advise me on what I should actually do? I guess these are question for those of you who have 'been there and done that'. So any guidance will be vary much appreciated. Many thanks in advance for your help.

• php/dos : How do you parse a regedit export file?

  - by phill

  My objective is to look for Company key-value in the registry hive and then pull the corresponding Guid and other keys and values following it. So I figured i would run the regedit export command and then parse the file with php for the keys I need. So after running the dos batch command >regedit /E "output.txt" "HKLM\System....\Company1" The output textfile seems to be in some kind of UNICODE format which isn't regex friendly. I'm using php to parse the file and pull the keys. Here is the php code i'm using to parse the file <?php $regfile = "output.txt"; $handle = fopen ("c:\\\\" . $regfile,"r"); //echo "handle: " . $file . "<br>"; $row = 1; while ((($data = fgets($handle, 1024)) !== FALSE) ) { $num = count($data); echo "$num fields in line $row: \n"; $reg_section = $data; //$reg_section = "[HKEY_LOCAL_MACHINE\SOFTWARE\TECHNOLOGIES\MEDIUS\CONFIG MANAGER\SYSTEM\COMPANIES\RECORD11]"; $pattern = "/^(\[HKEY_LOCAL_MACHINE\\\SOFTWARE\\\TECHNOLOGIES\\\MEDIUS\\\CONFIG MANAGER\\\SYSTEM\\\COMPANIES\\\RECORD(\d+)\])$/"; if ( preg_match($pattern, $reg_section )) { echo "<font color=red>Found</font><br>"; } else { echo "not found<br>"; echo $data . "<br>"; } $row++; } //end while fclose($handle); ?> and the output looks like this.... 1 fields in line 1: not found ÿþW?i?n?d?o?w?s? ?R?e?g?i?s?t?r?y? ?E?d?i?t?o?r? ?V?e?r?s?i?o?n? ?5?.?0?0? ? 1 fields in line 2: not found 1 fields in line 3: not found [?H?K?E?Y??L?O?C?A?L??M?A?C?H?I?N?E?\?S?O?F?T?W?A?R?E?\?I?N?T?E?R?S?T?A?R? ?T?E?C?H?N?O?L?O?G?I?E?S?\?X?M?E?D?I?U?S?\?C?O?N?F?I?G? ?M?A?N?A?G?E?R?\?S?Y?S?T?E?M?\?C?O?M?P?A?N?I?E?S?]? ? 1 fields in line 4: not found "?N?e?x?t? ?R?e?c?o?r?d? ?I?D?"?=?"?4?1?"? ? 1 fields in line 5: not found Any ideas how to approach this? thanks in advance

• Adjust parameters of serial port reading

  - by clinisbut

  Hello. I'm facing a particular issue that regards serial communication under win32. I'm communicating with a device can only accept frames when it is not already communicating. So I must find a valid frame and then inmediatelly send my request. I developed a class named Serial that handles basic operations on serial port (open, close, read, write) and then a Thread calls inside a loop read and write functions. Thread loop //Device is an object of class Serial while( device->isOpen() && !terminate ) { unsigned int readed = 0; unsigned long error = ERROR_SUCCESS; unsigned char* data = device->read( &readed, &error ); if( error==ERROR_SUCCESS ) { //If data received, deliver to upper level if( readed>0 ) { QByteArray output( (const char*)data, (signed int)readed ); emit dataArrived( output, readed ); } } else { //unrelated stuff } //Here I manage the writting issue //Only when nothing is received, and Upper layer wants to send a frame //(Upper layer only will mark as something to send when it detects a valid frame) if( readed==0 ) { out_lock.lock(); //If something to send... if( something_to_send > 0 ) { if( device->write( output_buffer, output_size, &error ) ) { //things... } } } } The Thread basically keeps reading, and when nothing is received, sees if somebody has signaled to send a frame (this means that a valid frame is just received). When this happens, it writes the frame through serial port. Here comes my problem. Inside the Serial::read() function: I use the overlapped way of reading: ::ClearCommError( handle, &dwErrors, &stat); if( stat.cbInQue ) { //If there's something to read, read it, please note the bytes to read parameter, here 1. bool ok = ::ReadFile( handle, buffer_in, 1, &bytes_read, &ov_reader ); if( !ok ) { DWORD _error = ::GetLastError(); if( _error == ERROR_IO_PENDING ) { DWORD result = ::WaitForMultipleObjects( 2, waiters, FALSE,INFINITE ); switch( result ) { //Eventshutdown case WAIT_OBJECT_0: /*code omitted*/break; case WAIT_OBJECT_0+1: ok = ::GetOverlappedResult( handle, &ov_reader, &bytes_read, true ); //check ok value omitted break; } } } } if( bytes_read>0 ) { *size = bytes_read; } Here starts my problem. When device sends me small frames (around 30 bytes) everything works fine, but when larger frames are sent, the code is not able to find any free time between frames causing the thread to never be able send any frame because readed is never 0. If I increase the number of bytes to read inside the read() function, lose the ability to detect when the device "listens": bool ok = ::ReadFile(handle, buffer_in, 50, &bytes_read, &ov_reader ); This happens because my app can receive the end of a frame together with the start of the next one. This behaviour is very common. In the other hand, if I change the INFINITE argument by a valid timeout in the WaitForMultipleObjects function, I lose data. So my question basically is... what I'm doing wrong? Why when reading 1 byte each time I don't find any free time to send my own frames? Thank you

• Dynamic loaded libraries and shared global symbols

  Since I observed some strange behavior of global variables in my dynamically loaded libraries, I wrote the following test. At first we need a statically linked library: The header test.hpp #ifndef __BASE_HPP #define __BASE_HPP #include <iostream> class test { private: int value; public: test(int value) : value(value) { std::cout << "test::test(int) : value = " << value << std::endl; } ~test() { std::cout << "test::~test() : value = " << value << std::endl; } int get_value() const { return value; } void set_value(int new_value) { value = new_value; } }; extern test global_test; #endif // __BASE_HPP and the source test.cpp #include "base.hpp" test global_test = test(1); Then I wrote a dynamically loaded library: library.cpp #include "base.hpp" extern "C" { test* get_global_test() { return &global_test; } } and a client program loading this library: client.cpp #include <iostream> #include <dlfcn.h> #include "base.hpp" typedef test* get_global_test_t(); int main() { global_test.set_value(2); // global_test from libbase.a std::cout << "client: " << global_test.get_value() << std::endl; void* handle = dlopen("./liblibrary.so", RTLD_LAZY); if (handle == NULL) { std::cout << dlerror() << std::endl; return 1; } get_global_test_t* get_global_test = NULL; void* func = dlsym(handle, "get_global_test"); if (func == NULL) { std::cout << dlerror() << std::endl; return 1; } else get_global_test = reinterpret_cast<get_global_test_t*>(func); test* t = get_global_test(); // global_test from liblibrary.so std::cout << "liblibrary.so: " << t->get_value() << std::endl; std::cout << "client: " << global_test.get_value() << std::endl; dlclose(handle); return 0; } Now I compile the statically loaded library with g++ -Wall -g -c base.cpp ar rcs libbase.a base.o the dynamically loaded library g++ -Wall -g -fPIC -shared library.cpp libbase.a -o liblibrary.so and the client g++ -Wall -g -ldl client.cpp libbase.a -o client Now I observe: The client and the dynamically loaded library possess a different version of the variable global_test. But in my project I'm using cmake. The build script looks like this: CMAKE_MINIMUM_REQUIRED(VERSION 2.6) PROJECT(globaltest) ADD_LIBRARY(base STATIC base.cpp) ADD_LIBRARY(library MODULE library.cpp) TARGET_LINK_LIBRARIES(library base) ADD_EXECUTABLE(client client.cpp) TARGET_LINK_LIBRARIES(client base dl) analyzing the created makefiles I found that cmake builds the client with g++ -Wall -g -ldl -rdynamic client.cpp libbase.a -o client This ends up in a slightly different but fatal behavior: The global_test of the client and the dynamically loaded library are the same but will be destroyed two times at the end of the program. Am I using cmake in a wrong way? Is it possible that the client and the dynamically loaded library use the same global_test but without this double destruction problem?

• COM port read - Thread remains alive after timeout occurs

  - by Sna

  Hello to all. I have a dll which includes a function called ReadPort that reads data from serial COM port, written in c/c++. This function is called within an extra thread from another WINAPI function using the _beginthreadex. When COM port has data to be read, the worker thread returns the data, ends normaly, the calling thread closes the worker's thread handle and the dll works fine. However, if ReadPort is called without data pending on the COM port, when timeout occurs then WaitForSingleObject returns WAIT_TIMEOUT but the worker thread never ends. As a result, virtual memory grows at about 1 MB every time, physical memory grows some KBs and the application that calls the dll becomes unstable. I also tryied to use TerminateThread() but i got the same results. I have to admit that although i have enough developing experience, i am not familiar with c/c++. I did a lot of research before posting but unfortunately i didn't manage to solve my problem. Does anyone have a clue on how could i solve this problem? However, I really want to stick to this kind of solution. Also, i want to mention that i think i can't use any global variables to use some kind of extra events, because each dll's functions may be called many times for every COM port. I post some parts of my code below: The Worker Thread: unsigned int __stdcall ReadPort(void* readstr){ DWORD dwError; int rres;DWORD dwCommModemStatus, dwBytesTransferred; int ret; char szBuff[64] = ""; ReadParams* params = (ReadParams*)readstr; ret = SetCommMask(params->param2, EV_RXCHAR | EV_CTS | EV_DSR | EV_RLSD | EV_RING); if (ret == 0) { _endthreadex(0); return -1; } ret = WaitCommEvent(params->param2, &dwCommModemStatus, 0); if (ret == 0) { _endthreadex(0); return -2; } ret = SetCommMask(params->param2, EV_RXCHAR | EV_CTS | EV_DSR | EV_RLSD| EV_RING); if (ret == 0) { _endthreadex(0); return -3; } if (dwCommModemStatus & EV_RXCHAR||dwCommModemStatus & EV_RLSD) { rres = ReadFile(params->param2, szBuff, 64, &dwBytesTransferred,NULL); if (rres == 0) { switch (dwError = GetLastError()) { case ERROR_HANDLE_EOF: _endthreadex(0); return -4; } _endthreadex(0); return -5; } else { strcpy(params->param1,szBuff); _endthreadex(0); return 0; } } else { _endthreadex(0); return 0; } _endthreadex(0); return 0;} The Calling Thread: int WINAPI StartReadThread(HANDLE porthandle, HWND windowhandle){ HANDLE hThread; unsigned threadID; ReadParams readstr; DWORD ret, ret2; readstr.param2 = porthandle; hThread = (HANDLE)_beginthreadex( NULL, 0, ReadPort, &readstr, 0, &threadID ); ret = WaitForSingleObject(hThread, 500); if (ret == WAIT_OBJECT_0) { CloseHandle(hThread); if (readstr.param1 != NULL) // Send message to GUI return 0; } else if (ret == WAIT_TIMEOUT) { ret2 = CloseHandle(hThread); return -1; } else { ret2 = CloseHandle(hThread); if (ret2 == 0) return -2; }} Thank you in advance, Sna.

• Usage of IcmpSendEcho2 with an asynchronous callback

  - by Ben Voigt

  I've been reading the MSDN documentation for IcmpSendEcho2 and it raises more questions than it answers. I'm familiar with asynchronous callbacks from other Win32 APIs such as ReadFileEx... I provide a buffer which I guarantee will be reserved for the driver's use until the operation completes with any result other than IO_PENDING, I get my callback in case of either success or failure (and call GetCompletionStatus to find out which). Timeouts are my responsibility and I can call CancelIo to abort processing, but the buffer is still reserved until the driver cancels the operation and calls my completion routine with a status of CANCELLED. And there's an OVERLAPPED structure which uniquely identifies the request through all of this. IcmpSendEcho2 doesn't use an OVERLAPPED context structure for asynchronous requests. And the documentation is unclear excessively minimalist about what happens if the ping times out or fails (failure would be lack of a network connection, a missing ARP entry for local peers, ICMP destination unreachable response from an intervening router for remote peers, etc). Does anyone know whether the callback occurs on timeout and/or failure? And especially, if no response comes, can I reuse the buffer for another call to IcmpSendEcho2 or is it forever reserved in case a reply comes in late? I'm wanting to use this function from a Win32 service, which means I have to get the error-handling cases right and I can't just leak buffers (or if the API does leak buffers, I have to use a helper process so I have a way to abandon requests). There's also an ugly incompatibility in the way the callback is made. It looks like the first parameter is consistent between the two signatures, so I should be able to use the newer PIO_APC_ROUTINE as long as I only use the second parameter if an OS version check returns Vista or newer? Although MSDN says "don't do a Windows version check", it seems like I need to, because the set of versions with the new argument aren't the same as the set of versions where the function exists in iphlpapi.dll. Pointers to additional documentation or working code which uses this function and an APC would be much appreciated. Please also let me know if this is completely the wrong approach -- i.e. if either using raw sockets or some combination of IcmpCreateFile+WriteFileEx+ReadFileEx would be more robust.

• Large Object Heap Fragmentation

  - by Paul Ruane

  The C#/.NET application I am working on is suffering from a slow memory leak. I have used CDB with SOS to try to determine what is happening but the data does not seem to make any sense so I was hoping one of you may have experienced this before. The application is running on the 64 bit framework. It is continuously calculating and serialising data to a remote host and is hitting the Large Object Heap (LOH) a fair bit. However, most of the LOH objects I expect to be transient: once the calculation is complete and has been sent to the remote host, the memory should be freed. What I am seeing, however, is a large number of (live) object arrays interleaved with free blocks of memory, e.g., taking a random segment from the LOH: 0:000> !DumpHeap 000000005b5b1000 000000006351da10 Address MT Size ... 000000005d4f92e0 0000064280c7c970 16147872 000000005e45f880 00000000001661d0 1901752 Free 000000005e62fd38 00000642788d8ba8 1056 <-- 000000005e630158 00000000001661d0 5988848 Free 000000005ebe6348 00000642788d8ba8 1056 000000005ebe6768 00000000001661d0 6481336 Free 000000005f214d20 00000642788d8ba8 1056 000000005f215140 00000000001661d0 7346016 Free 000000005f9168a0 00000642788d8ba8 1056 000000005f916cc0 00000000001661d0 7611648 Free 00000000600591c0 00000642788d8ba8 1056 00000000600595e0 00000000001661d0 264808 Free ... Obviously I would expect this to be the case if my application were creating long-lived, large objects during each calculation. (It does do this and I accept there will be a degree of LOH fragmentation but that is not the problem here.) The problem is the very small (1056 byte) object arrays you can see in the above dump which I cannot see in code being created and which are remaining rooted somehow. Also note that CDB is not reporting the type when the heap segment is dumped: I am not sure if this is related or not. If I dump the marked (<--) object, CDB/SOS reports it fine: 0:015> !DumpObj 000000005e62fd38 Name: System.Object[] MethodTable: 00000642788d8ba8 EEClass: 00000642789d7660 Size: 1056(0x420) bytes Array: Rank 1, Number of elements 128, Type CLASS Element Type: System.Object Fields: None The elements of the object array are all strings and the strings are recognisable as from our application code. Also, I am unable to find their GC roots as the !GCRoot command hangs and never comes back (I have even tried leaving it overnight). So, I would very much appreciate it if anyone could shed any light as to why these small (<85k) object arrays are ending up on the LOH: what situations will .NET put a small object array in there? Also, does anyone happen to know of an alternative way of ascertaining the roots of these objects? Thanks in advance. Update 1 Another theory I came up with late yesterday is that these object arrays started out large but have been shrunk leaving the blocks of free memory that are evident in the memory dumps. What makes me suspicious is that the object arrays always appear to be 1056 bytes long (128 elements), 128 * 8 for the references and 32 bytes of overhead. The idea is that perhaps some unsafe code in a library or in the CLR is corrupting the number of elements field in the array header. Bit of a long shot I know... Update 2 Thanks to Brian Rasmussen (see accepted answer) the problem has been identified as fragmentation of the LOH caused by the string intern table! I wrote a quick test application to confirm this: static void Main() { const int ITERATIONS = 100000; for (int index = 0; index < ITERATIONS; ++index) { string str = "NonInterned" + index; Console.Out.WriteLine(str); } Console.Out.WriteLine("Continue."); Console.In.ReadLine(); for (int index = 0; index < ITERATIONS; ++index) { string str = string.Intern("Interned" + index); Console.Out.WriteLine(str); } Console.Out.WriteLine("Continue?"); Console.In.ReadLine(); } The application first creates and dereferences unique strings in a loop. This is just to prove that the memory does not leak in this scenario. Obviously it should not and it does not. In the second loop, unique strings are created and interned. This action roots them in the intern table. What I did not realise is how the intern table is represented. It appears it consists of a set of pages -- object arrays of 128 string elements -- that are created in the LOH. This is more evident in CDB/SOS: 0:000> .loadby sos mscorwks 0:000> !EEHeap -gc Number of GC Heaps: 1 generation 0 starts at 0x00f7a9b0 generation 1 starts at 0x00e79c3c generation 2 starts at 0x00b21000 ephemeral segment allocation context: none segment begin allocated size 00b20000 00b21000 010029bc 0x004e19bc(5118396) Large object heap starts at 0x01b21000 segment begin allocated size 01b20000 01b21000 01b8ade0 0x00069de0(433632) Total Size 0x54b79c(5552028) ------------------------------ GC Heap Size 0x54b79c(5552028) Taking a dump of the LOH segment reveals the pattern I saw in the leaking application: 0:000> !DumpHeap 01b21000 01b8ade0 ... 01b8a120 793040bc 528 01b8a330 00175e88 16 Free 01b8a340 793040bc 528 01b8a550 00175e88 16 Free 01b8a560 793040bc 528 01b8a770 00175e88 16 Free 01b8a780 793040bc 528 01b8a990 00175e88 16 Free 01b8a9a0 793040bc 528 01b8abb0 00175e88 16 Free 01b8abc0 793040bc 528 01b8add0 00175e88 16 Free total 1568 objects Statistics: MT Count TotalSize Class Name 00175e88 784 12544 Free 793040bc 784 421088 System.Object[] Total 1568 objects Note that the object array size is 528 (rather than 1056) because my workstation is 32 bit and the application server is 64 bit. The object arrays are still 128 elements long. So the moral to this story is to be very careful interning. If the string you are interning is not known to be a member of a finite set then your application will leak due to fragmentation of the LOH, at least in version 2 of the CLR. In our application's case, there is general code in the deserialisation code path that interns entity identifiers during unmarshalling: I now strongly suspect this is the culprit. However, the developer's intentions were obviously good as they wanted to make sure that if the same entity is deserialised multiple times then only one instance of the identifier string will be maintained in memory.

• FastMM log to file without FullDebugMode

  - by dmauric.mp

  I'd like to get FastMM memory leak report that shows up on app shutdown, but in a file instead of the dialog box. The idea is to use it in a release build as I have trouble reproducing the leaks. I would however prefer to not use the FullDebugMode which seems to be required for logging to a file. Am I missing anything or is this not supported ?

• Marshalling to a native library in C#

  - by Daniel Baulig

  I'm having trouble calling functions of a native library from within managed C# code. I am developing for the 3.5 compact framework (Windows Mobile 6.x) just in case this would make any difference. I am working with the waveIn* functions from coredll.dll (these are in winmm.dll in regular Windows I believe). This is what I came up with: // namespace winmm; class winmm [StructLayout(LayoutKind.Sequential)] public struct WAVEFORMAT { public ushort wFormatTag; public ushort nChannels; public uint nSamplesPerSec; public uint nAvgBytesPerSec; public ushort nBlockAlign; public ushort wBitsPerSample; public ushort cbSize; } [StructLayout(LayoutKind.Sequential)] public struct WAVEHDR { public IntPtr lpData; public uint dwBufferLength; public uint dwBytesRecorded; public IntPtr dwUser; public uint dwFlags; public uint dwLoops; public IntPtr lpNext; public IntPtr reserved; } public delegate void AudioRecordingDelegate(IntPtr deviceHandle, uint message, IntPtr instance, ref WAVEHDR wavehdr, IntPtr reserved2); [DllImport("coredll.dll")] public static extern int waveInAddBuffer(IntPtr hWaveIn, ref WAVEHDR lpWaveHdr, uint cWaveHdrSize); [DllImport("coredll.dll")] public static extern int waveInPrepareHeader(IntPtr hWaveIn, ref WAVEHDR lpWaveHdr, uint Size); [DllImport("coredll.dll")] public static extern int waveInStart(IntPtr hWaveIn); // some other class private WinMM.WinMM.AudioRecordingDelegate waveIn; private IntPtr handle; private uint bufferLength; private void setupBuffer() { byte[] buffer = new byte[bufferLength]; GCHandle bufferPin = GCHandle.Alloc(buffer, GCHandleType.Pinned); WinMM.WinMM.WAVEHDR hdr = new WinMM.WinMM.WAVEHDR(); hdr.lpData = bufferPin.AddrOfPinnedObject(); hdr.dwBufferLength = this.bufferLength; hdr.dwFlags = 0; int i = WinMM.WinMM.waveInPrepareHeader(this.handle, ref hdr, Convert.ToUInt32(Marshal.SizeOf(hdr))); if (i != WinMM.WinMM.MMSYSERR_NOERROR) { this.Text = "Error: waveInPrepare"; return; } i = WinMM.WinMM.waveInAddBuffer(this.handle, ref hdr, Convert.ToUInt32(Marshal.SizeOf(hdr))); if (i != WinMM.WinMM.MMSYSERR_NOERROR) { this.Text = "Error: waveInAddrBuffer"; return; } } private void setupWaveIn() { WinMM.WinMM.WAVEFORMAT format = new WinMM.WinMM.WAVEFORMAT(); format.wFormatTag = WinMM.WinMM.WAVE_FORMAT_PCM; format.nChannels = 1; format.nSamplesPerSec = 8000; format.wBitsPerSample = 8; format.nBlockAlign = Convert.ToUInt16(format.nChannels * format.wBitsPerSample); format.nAvgBytesPerSec = format.nSamplesPerSec * format.nBlockAlign; this.bufferLength = format.nAvgBytesPerSec; format.cbSize = 0; int i = WinMM.WinMM.waveInOpen(out this.handle, WinMM.WinMM.WAVE_MAPPER, ref format, Marshal.GetFunctionPointerForDelegate(waveIn), 0, WinMM.WinMM.CALLBACK_FUNCTION); if (i != WinMM.WinMM.MMSYSERR_NOERROR) { this.Text = "Error: waveInOpen"; return; } setupBuffer(); WinMM.WinMM.waveInStart(this.handle); } I read alot about marshalling the last few days, nevertheless I do not get this code working. When my callback function is called (waveIn) when the buffer is full, the hdr structure passed back in wavehdr is obviously corrupted. Here is an examlpe of how the structure looks like at that point: - wavehdr {WinMM.WinMM.WAVEHDR} WinMM.WinMM.WAVEHDR dwBufferLength 0x19904c00 uint dwBytesRecorded 0x0000fa00 uint dwFlags 0x00000003 uint dwLoops 0x1990f6a4 uint + dwUser 0x00000000 System.IntPtr + lpData 0x00000000 System.IntPtr + lpNext 0x00000000 System.IntPtr + reserved 0x7c07c9a0 System.IntPtr This obiously is not what I expected to get passed. I am clearly concerned about the order of the fields in the view. I do not know if Visual Studio .NET cares about actual memory order when displaying the record in the "local"-view, but they are obviously not displayed in the order I speciefied in the struct. Then theres no data pointer and the bufferLength field is far to high. Interestingly the bytesRecorded field is exactly 64000 - bufferLength and bytesRecorded I'd expect both to be 64000 though. I do not know what exactly is going wrong, maybe someone can help me out on this. I'm an absolute noob to managed code programming and marshalling so please don't be too harsh to me for all the stupid things I've propably done. Oh here's the C code definition for WAVEHDR which I found here, I believe I might have done something wrong in the C# struct definition: /* wave data block header */ typedef struct wavehdr_tag { LPSTR lpData; /* pointer to locked data buffer */ DWORD dwBufferLength; /* length of data buffer */ DWORD dwBytesRecorded; /* used for input only */ DWORD_PTR dwUser; /* for client's use */ DWORD dwFlags; /* assorted flags (see defines) */ DWORD dwLoops; /* loop control counter */ struct wavehdr_tag FAR *lpNext; /* reserved for driver */ DWORD_PTR reserved; /* reserved for driver */ } WAVEHDR, *PWAVEHDR, NEAR *NPWAVEHDR, FAR *LPWAVEHDR; If you are used to work with all those low level tools like pointer-arithmetic, casts, etc starting writing managed code is a pain in the ass. It's like trying to learn how to swim with your hands tied on your back. Some things I tried (to no effect): .NET compact framework does not seem to support the Pack = 2^x directive in [StructLayout]. I tried [StructLayout(LayoutKind.Explicit)] and used 4 bytes and 8 bytes alignment. 4 bytes alignmentgave me the same result as the above code and 8 bytes alignment only made things worse - but that's what I expected. Interestingly if I move the code from setupBuffer into the setupWaveIn and do not declare the GCHandle in the context of the class but in a local context of setupWaveIn the struct returned by the callback function does not seem to be corrupted. I am not sure however why this is the case and how I can use this knowledge to fix my code. I'd really appreciate any good links on marshalling, calling unmanaged code from C#, etc. Then I'd be very happy if someone could point out my mistakes. What am I doing wrong? Why do I not get what I'd expect.
