• .NET Development asynchronous operations issues....

  Hi guys, I have a problem with FileStream object!!! By using something like; processHandle = OpenProcess( ProcessAccessRights .PROCESS_DUP_HANDLE, false , processId); if ( DuplicateHandle(processHandle.DangerousGetHandle(), handle, currentProcess, out objectHandle, 0, false , DuplicateHandleOptions .DUPLICATE_SAME_ACCESS)) { handle = objectHandle.DangerousGetHandle(); } FileStream s = new FileStream (objectHandle.DangerousGetHandle(), FileAccess .Read, true ,128, true ); First time I run it it works without problems but second, third,.... time when I fire it it gives the following error; Handle does not support asynchronous operations.

• Visual Studio Crystal Report help needed

  I m using C# and Crystal report for some sort of reporting. I have visual studio .net installed. My application working fine in my PC and crystal report also working. But in another PC (where visual studio in not installed) I first install .net framework. Then I run my application, it works fine, but exception raised when I tried to view crystal report viewer. The exception is (I don't remember exactly) "Could not start CrystalDesigner. _________ .Engine" Hi, It sounds like you did not include the Crystal merge modules with your project.

• Windows Networking Development TDI client/protocol interaction

  Hi, I am trying to write a TDI client driver and Protocol driver on Windows Server 2003. I want my protocol driver to report NIC binding ADD/DEL events to the TDI client. I registered for TdiRegisterPnPHandlers in my client . When a NIC binding is added (or deleted) , I call TdiRegisterDeviceObject ( or DeRegister) in my protocol driver. But I dont see my clients ClientPnPBindingChange routine being called with TDI_PNP_OP_ADD (or TDI_PNP_OP_DEL). Another problem is that I am able to receive ClientPnPAddNetAddress (or ClientPnPDelNetAddress) from the TCPIP module when network address changes occur, but I am not able to do the same from my protocol driver. I call TdiRegisterNetAddress (or TdiDeregisterNetAddress) from the protocol driver bu ...Show All

• Visual Basic Locate mouse position of hovered tabpage

  I'm creating a tabbed browser app where each page is dynamically created and named. I need to use the mousehover event but don't know how to determine which tabpage is in the hover state. VB.NET documentation mentions the MouseEventArgs class but when I try to add a new mousehover delegate, VB will not accept this signiture in place of the required System.EventArgs. Bottom line: the app contains a main form with a 'New Tab' checkbox. If checked and address bar URL is navigated, a new tabpage is dynamically added to the tabcontrol and named "wbTabPage" & << the new tab's index >>. I want to raise the mousehover event whenever this new dynamically created tabpage is hovered. I searched for three days for infor ...Show All

• Visual Studio 2008 (Pre-release) WPF application makes call to server through WCF and hangs

  Hi, OK, this is what we did: Created two console applications, one server, one client. Implemented an server interface and callback. After setting the config files on server and client (using named pipes and WCF) we got everything to work. We are making a call to the server, and within this call, the server calls the client back [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single,ConcurrencyMode=ConcurrencyMode.Reentrant)] Then we switched the client to a WPF (STAThreading). When the WPF app calls the server, the call makes it to the server, but never comes back. The client just times out... The really weird thing is that this only happens if we create the service in the Button handler, code looks like this: [Button handler c ...Show All

• Visual Studio Namespace-level comments in Sandcastle?

  Hi Anand, We have been using NamespaceDoc.cs to supply namespace-level comments to NDoc. Does Sandcastle allow for namespace-level comments If not, is there a plan to incorporate them at some point Thanks, Richard Hi Anand, I tried including a comment at the namespace level, and it doesn't show up in my XML file. Here is what I did (I have changed the actual namespace and class names, which are internal): using System; ... using System.Xml.Xsl; /// This is the namespace namespace the.namespace { /// This is the class public sealed class TheClass: BaseClass { ...

• SQL Server Integration Services won't install

• Visual Studio MSBuild + AssemblyInfoTask + InstallShield

  So I have been having some trouble coming up with a good solution to manage the version numbers in my automated build process. Here's what I've got going so far: I have the AssemblyInfoTask updating all the AssemblyInfo.cs files appropriately. Once all my code is compiled I would then like to build the InstallShield installer for my application. InstallShield takes a product version parameter which is accessible in the InstallShield project file. So I'm wanting to update the version number in the InstallShield project to that which was generated by the AssemblyInfoTask. However, there does not appear to be a way to retreive the version number that was generated. I statically assign the major and minor version numbers for the Assem ...Show All

• Visual Basic HELP! Getting nothing reading/writing to COM1

  I downloaded "UsingTheSerialPort" as part of the VB 101 samples. When I run it, I do not get any sort of reply or indication that my text is being sent to the device I have attached to COM1 via an RS232 Null Modem cable. Stepping through the code with Debug shows that the ReadLine() code in the sample never gets executed and I'm not getting any error messages or warnings. I added displays and code to verfiy that the port is open: ComVal = SerialPort1.IsOpen MessageBox.Show( "Com1 Open:" & ComVal) I set ComVal to False when it is declared and it displays as True after the open on COM1. I'm fairly new to Visual Studio and VB 2005 so I'm hoping that someone has some good suggestions. ======= ...Show All

• SQL Server compression in SP2

  Hi there. I heard Paul Flessner at PASS talk about compression in SP2 for SS05 and results that showed like 40% compression on some SAP tables -- so that made me happy! When I looked around SP2 I think I"m seeing compression is a new data type that would act like a varying data type for numerics. Is this correct, or am I am I missing something (I asked folks at PASS, but not too many people seemed to know about this). Can you let me know how this works. 40% seems worth it, what do I have to do to get it going Should I use it Thanks... This feature is called "vardecimal".  For information, see this blog post by Kalen Delaney:   http://sqlblog.com/blogs/kalen ...Show All
