• Windows Forms How to Northwind Databind to Customers and Orders row at once

(also setting the foreign key (order_row or customer_row) does not work!) Thanks Peter ...Show All

• .NET Development Best Practices: Generating Serial Numbers which contain informations?

  Hello Forum Users, i am working on a Software which can be registered by people and companies for variable period like 3 months, 6 months or one year and so on. For example, we receive the order from company X, purchasing the software license for 6 Months. Now we would like to use our own Serial number generator and pass in the name of the company and the period and generate a serial number, which will be delivered to the customer by e-mail, phone, fax, letter etc. We would like to be able to show the information on the customers screen (so that he hardly would like to use someone else key), and be able to disa ...Show All

• Visual Studio Tools for Office VSTO install balks at VS 2005 beta

  Sorry for the cross-post; I posted this in the VS forum as well. A few months ago, like everyone else, I installed the release version of VS 2005 Professional after having gone through the uninstall of the beta version. I recently downloaded the VSTO install, but it seems to think I still have betas for VS 2005 and VSS 2005 installed. I get the following message when I run setup.exe: Thanks you for particiapting in the beta program. You must uninstall pre-release products in a specific order before you can continue with setup.

• Smart Device Development Do any communication libraries exsist in the CF?

  Does any of the .NET TCP/IP classes exsist in the .NET Compact Framework (1 or 2) I want to mess around with some NNTP stuff (Where I was using a regular C# class for reference) and it uses these. Are there any networking protocals in the CF Thanks! Easiest is to add a reference to all the netcf assemblies and then let intellisense be your guide. I would not trust the documentation at this beta stage but it will have good clues (msdn library at msdn2). Also look at the Object Browser which in VS2005 has additional filtering.

• .NET Development Error adding web service reference

  The wsdl file is legitimate. I verified it on Mozilla, but not on IIS6.0. When I try to create a client, I try the utility to get the web reference. At this point, I get this message.

• Visual Basic Good coding practice -> Multiple platforms project

  Hi, Being new to VS 2005 I face a project which targets PC, PPC and SmartPhones. Basically all the code is the same, just a few changes due to CF for Smart Devices. Only the forms are different due to the difference on the screens. Right now I have three different projects, one for each platform, so if I make some change in the code I need to copy and paste in the others. I suppose this is a bad practice and should be a better way to do this. Any help will be very welcome. TIA, Jose Adell Put common code into a Single class Library which can be called from 3 projects which deal with UI etc ...Show All

• Visual Studio Team System Code Coverage not worknig properly during a team build

  Hello I have a problem with the team builds. In my proj file I have specified to build my solution, to run tests without specifying any test list. All my tests run correctly.
