• Software Development for Windows Vista How to pass parameters from one workflow to another?

  I have one workflow (workflow1) defined, and it contains a property isAuthorized. Then I have defined Workflow2 and used the invoke workflow activity to invoke workflow1 in workflow2. When the workflow1, which is a part of workflow2, is completed, I need to read the value of isAuthorized property to determine which activity in workflow2 should be invoked. How can I read that value (isAuthorized) in workflow2 Thanks, Marko Vuksanovic. Marko, the InvokeWorkflowActivity will start workflow1 asynchronously. Passing parameters (via binding) is easy, but retrieving them when you need them is another story; that's why Jon has developed his custom activity & WorkflowRuntime Service. Serge ...Show All

• Software Development for Windows Vista Errors in winnt.h file using visual c++ 2005 express edition and mar. 15 sdk

  Hello. I get the following errors when I try to include winnt.h in my code. I tried using the newest sdk as well as the previous release, and both files seem to generate the same errors. This must be a common problem, but I haven't seen the answer. I'm including stdio.h, xlcall.h, windef.h and winnt.h in my code. Maybe I need to include another header. Any help would be greatly appreciated. Thanks.

• SQL Server How to stop PAD_INDEX being scripted

  Our team checks SQL scripts into version control. On my machine, however, the generated script always differs slightly. When I generate a create table script, the primary key part always has PAD_INDEX = OFF. Nobody else's server generates this. Does anyone know what option or setting I need to change to prevent PAD_INDEX = OFF from being output WITH ( PAD_INDEX = OFF , IGNORE_DUP_KEY = OFF ) ON [PRIMARY] BOL specifies When creating indexed views or manipulating rows in tables participating in an indexed view, seven SET options must be assigned specific values. The SET options ARITHABORT, CONCAT_NULL_YIELDS_NULL, QUOTED_IDENTIFIER, ANSI_NULLS, ANSI_PADDING, and ANSI_WARNINGS must be ON. T ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. C# Performance Problems

  Hi, I recognized, that my framerate is very bad in comparison with some C++ examples. After removing all "catchs" in the render-methods i got 100 FPS instead of 20. Exceptions seems to be really, really slow. Are there some other performace problems in C# which i have to have in mind Exceptions are very slow. When they are thrown. However the try/catch construct adds very little overhead by its self, of course even a little overhead adds up if you're processing 100's every render pass. What did your code look like ...Show All

• .NET Development SerializationException on Sending Data Back to Serviced Component Via Remoting

  I've developed a distributed app in C#. The various components of the application are as follows: A SQL Server database. Data Access Layer - Hosted in COM+ as Library application. Business Logic Layer - Hosted in COM+ as Server application. User Interface (Windows-based). Types - Exposes various typed DataSet objects used by DAL, BLL, and UI. ServerHost - A Console app that exposes the BLL objects via remoting. The application is hosted on a machine running Windows XP SP2. The DAL and BLL are both hosted in COM+ on the same server that hosts the SQL Server database. Both of these projects and the UI project reference the Types library that, among other things, has strongly typed DataSet objects that are used by the ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Game.Tick

  Rather than using Game.Run, I need to manually handle the game loop. Sort of like this equivalent scenario using winforms: someForm.Show(); while(someForm.Created) { //Insert rendering stuff here Application.DoEvents(); } So, how would I use Game.Tick() to accomplish the same thing I see that there's a Game.IsActive property, but it returns false when I try the following: while(myGame.IsActive) { //Insert rendering stuff here myGame.Tick(); } This of course exits immediately. I assume I need to get the game active before calling Tick; can I do that without Game.Run() Exactly, if you create your graphics engine using the gamecomponent model (and the gameservices for allowing access to it from other ...Show All

• Visual Studio 2008 (Pre-release) namespace declared at Envelope Level are not taken into account...

  The problem occurs with .NET3 RC1 when trying to deserialize a DataContract which has a DataMember of type System.Object (xs:anytype) If the namespaces "xsi" and "xs" are defined at the Envelope level, they are NOT taken into account while deserializing the FaultContract. For example : in the following XML message, the namespaces "xsi" and "xs" are defined at Envelope level and are used in the "paramValue" dataMember of the CreateAddressFailedException FaultContract. When trying to deserialize using a DataContractSerializer, we get the following exception : Server stack trace: at System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime operation, ProxyRpc& rpc) at System.ServiceModel.Channe ...Show All

• Windows Forms How to get or read the last letter from a text box? - Vb.net or VS 2005

  Hi I have a TextBox in a windows form to enter 10 digit number followed by 2 letters. (Ex: 304528929 GH ) I have a code (got from my other thread) to calculate the total of the above digits(3+0+4+....) and dividing the total by someother value to get the reminder . IT ALL WORKS FINE Also I have list of alphabets with equivalant value like below A = 3 B = 7 C = 1 H = 12 ........ ........ Z = 22 My question: If the reminder matches one of the above list , for example reminder from the above calculation is 12. So it matches with H = 12 . So If H is the last letter of 304528929 GH , then the user input is right. In Short : HOW DO I GET THE LAST LETTER (ex. 'H' in the above case) From the textbox and check w ...Show All

• Software Development for Windows Vista Custom Activity and DependencyProperty problem

  Hi, I'm currently developing some activities to implement some human workflows with microsoft workflow foundation but i've got two problems with the "Dependency Properties". 1 - the [ DefaultValue (maValue )] works only if my property is a enum or a bool. If my property is a string or a int, the defaultvalue display is respectively set to "" or 0. 2 - If i try to use a custom activity A, which have a output propery, inside a more complex one B, i can't retrieve the output property of activity A to get to the activity B: the property A is always set to null value. This problem doesn't occur if i try to use my activity A directly in a SequentialWorkflow. Thx in advance for your help. Pat. A sample of a P ...Show All

• Visual Studio Express Editions DVD player

  is it possiable to make DVD software to play movies , like the software you can buy...Like intervideo and programs like that . not exactly. in order to use your software created in .NET 2.0, the other computers also need to have .NET Framework 2.0 to run your software, without it it will not run you would need to create your own filters/parsers/codecs to play DVD files which may not be possible in .NET 2.0 (but dont quote me) to play the DVD. You can however embed a WMP Control in your application and use that to play your DVD/audio files but in terms of redistributing it you would need to contact Microsoft for the licensing portion about it. Another way would be to use perhaps some 3rd p ...Show All
