• .NET Development Get worksheet by name from an excel worksheet

  Howdy, I am working on a project to get data from excel spreadsheets and update an Access database with the new records. The excel spreadsheets are being generated by another department and I have no control over when they are being produced, or how they are being named. I think I have how to access the spreadsheet and extract the data to a DataSet (it seems straightforward). However, to select the data out of the workbook it looks like I need to explicitly name the worksheet that the data is on. Right now there is only ever ONE worksheet in the workbook, but it is NOT named 'Sheet1', the name is automatically generated by the equipment that is outputting the sheets. Here is an excerpt from what I have right now: ' How to get data from ...Show All

• Visual Studio Express Editions Currently Playing Media

  Hi, I'm making a utility that needs to monitor when the audio changes that you are listening to in Media Player, is there anyway to do this What I want is an effect simular to the Media Information option in messenger, where Media Information updates as your song changes, etc. Any thoughts I would be gratefull, thankyou. you would need to use some plugin/interface from that media player into your application. I don't believe there is a direct way of accessing the currently active media file playing since you need to implement that component into your application which then the media player app will alert its subscribers of the file that is playing. Try obtaining some SDK for the application in question and see if it supports ...Show All

• Software Development for Windows Vista Host a statemachine and have multiple client applications receive events

  Hello, I would like to have an application hosting a number of state machine workflows and have a number of client applications post events to update the workflow and receive the events to notify the client applications of these updates. Is this possible and if so can anyone point me in the direction of a sample. TIA Trevor. Lab 1 illustrates  communication between 1 or several client app and the host application : from the client to the server. If I understand, the next problem is: when 1 client update the workflow you want the others apps to be notified; it's not a workflow problem, but just a communication problem from a server (the host) and the other client apps ex client 1 send an event ...Show All

• Visual Studio Team System MSF Documentation: RUP vs. MSF - A comparative study

  L.S., This thesis makes a comparative study of two software engineering processes, namely the commonly used IBM Rational Unified Process and the new Microsoft Solutions Framework for Agile Software Development. Both software engineering processes have the same objective, to create a solution that meets the needs and expectations of the stakeholders. However, they have different approaches to reach their goal. The Rational Unified Process focuses on the time schedules and budget to create a predictable and disciplined software development environment. Microsoft Solutions Framework for Agile Software Development does not believe in predictability, it considers the fact that changes are inevitable and do occur during the software devel ...Show All

• Software Development for Windows Vista Pattern for email approval?

  With a workflow hosted by a desktop application, we want to add an email-based approval to a workflow. It is clear how to send an email as part of a workflow, but what do you recommend for waiting for approval-via email Because the workflow is hosted by a desktop application, the workflow runtime might not be running when the approval email is returned. Michael your service (the workflow host) polls your mail server (if it's exchange your can use CDO or extendedMapi I think; maybe is there a class in .Net framework 2.0 for this) and sends an event to your workflow which is waiting for it. ...Show All

• Visual C# Error handling

  Hi, I'm developing a three tier application, and have some conceptual question about the right way for error handling. the tiers are : 1. Presentation Layers - PL 2. Businnes Logic Layer - BLL 3.
