• .NET Development FileWatcher Service doesnt watch outiside of debugger!

  I created a FileWatcher Service. There is too much code to paste. When I start the service, then start the debugger, it works perfectly. However when I just run the service, it doesnt do anything! Why would it work when debugging but not on its own If you need to see some code, just let me know what portion you would want to view... thanks all. It was an educated guess. A service is not allowed to interact with the desktop and doesn't have a console window. The debugger provides a 'hook' to display console output to the Output window. Without a debugger or a console window, there is nowhere for the output to go... ...Show All

• .NET Development Delphi BDS 2006 and Visual Studio 2005 Development

  I am looking to see if this can be accomplished and if so, how: 1) Create a .NET application in Delphi BDS 2006, throw on a couple buttons, labels, or whatever (maybe even tie to a DB) 2) Save and run - fine 3) Open the Solution created above in Visual Studio 2005 and be able to a) edit the form in design mode, modify code, recompile and run 4) Be able to go BACK to BDS 2006 and see the modifications made in VS 2005 and also make changes 5) Go back and forth as described. Can this be done How VS 2005 cannot understand Delphi so it cannot parse or compile your Delphi code. So with a pure VS I would say "no go". Maybe someone comes up with an integration add in to make VS "understand" D ...Show All

  Hi; I have a J# app that has two worker threads. One thread is waiting on a MulticastSocket.receive() and the other on a DatagramSocket.receive(). I have a nunit (not junit) test that causes my app to get set up which includes these two worker daemons.

• Software Development for Windows Vista workflow designer

  Hi All, I wonder whether it is possible to host the workflow designer in my app.  I thought it would be cool if I can have the workflow designer as my app's GUI. Thanks, DK Hi Mark, I've been using the Workflow Monitor, but for some reason my workflows only show up in the monitor after my entire workflow has completed. The monitor doesn't show anything while the workflow is running. I'm selecting "ALL" events in the filter... I've even checked the database tables to see whether things are being added in the tracking tables, and they are being populated properly... Is there something else I need to configure Is this expected behavior Thanks, Randy ...Show All

• Software Development for Windows Vista Designer re-hosting and custom activities inside xoml-> NullReferenceException during GetRootActivity()

  Currently I'm trying to re-host the workflow designer, who's not ;) But I'm failling with each mdsn code sample when I try to load a custom xoml workflow. I end up with a NullReferenceException during the GetRootActivity() method or I see an empy diagram showing nothing but emptyness ;( I know that there is TypeLoader service available, I've added my assembly to this typeloader before the WorkflowLoader tries to load (create instance of) the workflow and it's custom written activities. I would like to load a xoml based workflow with custom activites inside the rehosted designer, what am I missing Thanks Hi Kushal, That's not possible due to copyright rules in my company.

• SQL Server Entering Notes/Comments/Remarks to Report

  Hi, there, We intended to create a report that allows users to enter remarks, comments or additional notes in supporting the report. Can it be done in SSRS FYI, we are using SQL Server 2005 Enterprise. Thank you. Regards, Yong Hwee You want to annotate within the report, or you want to add extended properties to the report If it is the first, then there is no way without changing the RDL or annotating the exported format. If it is the second, then you can use SetProperties/GetProperties to write/retrieve extended properties (including your annotations) programmatically. ...Show All

• Visual C# Passing an inherited class as 'T' to a generic container.

  I'm having trouble finding out how to use a general purpose generic container I wrote as a member of another class which wants to hold any class type based on a common base class. The first set of code below shows 4 seperate classes, RNode is a generic class, TreeControl has an RNode<TreeItemBase> member, and a "Root" property to access it, TreeItemBase is a control (not really important to this), and TreeItemHeader is derived from TreeIItemBase...

• Gadgets Another ActiveX/Com Question

  I am trying to interface a gadget with a C++ function in a DLL that needs to send back multiple data values. If I were calling this function from within another C++ program, I would just use reference variables for the function to update, but I don't know how to do anything like that in javascript. I'm sure there's a simple way, but I'm pretty new to javascript, so any help would be great. The language that the DLL is written in shouldn't matter as long as it is a legitimate COM DLL. In that situation, you would establish the ActiveX control as an object within the HTML of the page, give it an ID, and call the method with the syntax "ID.methd(param1,param2)". Here's the oversimplified approach ...Show All
