Software Development for Windows Vista Architectural question about WWF
Hi there, I'm just investigation the possibility to use WWF in an Orderrouting System. The system has relatively huge number of different routing objects (orders and group of orders) (about 100k objects). The system works in PUSH mode, means every workflow state transition is forced by event (like insert, update, delete of objects). My question is. What is the best use of the WWF components in this case 1. Having a stand-alone Workflow server, listening for user events. In this case, middle-tier will notify Workflow server that an order is changed and force workflow to continue. Is it possible to have 100K workflow instances ( ...Show All
Architecture Spcification of web services you need from third-party company
I want third-party company to implement bunch of web services. I wonder what it is the best way to specify them. I can create wsdl for them, is it ok Interoperability is very important because services will run on non-windows machine and clients will run on windows boxes. thanks in advance for any info Pawel, Are you saying that you want them to use web services that you have implemented We have toyed with this question ourselves. There are, basically, two avenues of approach: Deploy your wsdl in a public or client-accessible arena, point them to it, and wish them luck. Or, what we have considered, and begun doing, is creat ...Show All
Windows Live Developer Forums Connection problems in game/app
Hi I've been testing my game since it got approved and I've found that I cannot play with my contacts. My game is hosted in my own web server running in the same subnet as the computer from where I'm connected. I could play with my contacts using msgrp2p.xml file, but from the page it never calls the Channel_OnRemoteAppLoaded function. I think it has something to do with connectio speed to the server, since I can get faster from here to it. I've tried to delay the Initialize function call 1 or 2 seconds when the user comes from the subnet but it doesn't work. Any idea Thanks L I've got it. It was a prob ...Show All
.NET Development Returning a pdf-file from a webservice
I am returning a pdf-file from a webservice. I am thinking of just returning it as a byte array, but I am wondering whether there is a better way to return it. Speed is an issue and the pdf-file is quite small, so I have to avoid a solution which requires returning much more data. Treat PDF as binary, i.e., byte array, is the fastest way to get it from web service. If you want faster than web service, you can write a Http handler, ashx, and an ashx client to invoke the ashx, to get it as binary, not base64 string as in SOAP. Web method uses base64 string for binary data. Base64 encoding turns 3 bytes ...Show All

Visual Studio 'Unable to find the report in the manifest resources' - Build Action is missing??!
Hello, I have just upgraded my VS2003 project to VS2005. Had a million things to fix, but I'm finally down to the last few. The biggest remaining problem is my Crystal Reports don't work. The error message is below... On googling it the answer seems to be I have to include the *.rpt's as an embedded resource. However, and this is the really odd bit, the properties that should show up in VS2005 to allow me to do that are simply missing! No matter how I fool around with it, there is no Build Action property when I select a file in the Solution Explorer. I notice that if I create a Windows application in VS, the Build Action property ( ...Show All
SQL Server deleting records
I have a couple SQL tables that have been appended to daily over the last two years. There is now about 50,000,000 records in the table. Does anyone know the fastest way to delete records before a certain date to shorten these tables Delete queries and everything else I've tried is taking way too long. Since this is the first time you are deleting from the table - yes, you are just going to have to let the thing run - deleting many rows (and logging) just plain takes time. In the future, as this becomes a regular process (perhaps monthly) the index will help a great deal. .....gtr ...Show All
