• Visual Studio Express Editions unit testing & Express editions

  What options are available for unit testing with the Express editions While you can certainly use standalone unit testers like NUnit to test Express-built code, you can't attach to NUnit's process to enable debugging NUnit tests, and the unit test frameworks that install as add-ins are out, given no add-in capability with Express. Jamie Cansdale had a solution that involved hooking the Express process to install TestDriven.NET, but some sort of dispute with Microsoft seems to have killed that option too. What does that leave You may argue that hobbyists, novices, and students, teh primary audience for Express, don't need unit testing, but I beg to differ. This is actually a big issue for me, as I'm working on an introductory-level book ...Show All

• SQL Server Reporting Service vs UDM

  I am new to both technologies and would has been reading UDM on how to create a cube. My orginal intention is to create cubes for efficient retrieval of data which ends up in reports managment in an application. Can anyone elaborates on how the reporting service differs from UDM ( or what reporting services are )I thought they are mutually exclusive Thanks. Regards Alu Does it mean that the report service generates reports from OLTP database if the UDM is not created Does it mean UDM can work with reporting serivce which theortically speaking making the best of both if implemented Thanks.

• Visual Studio Team System Using Excel data source with a Load test - works for 1 user but not for 10 users

  Hello, I have a webtest that uses an Excel sheet data source. (The same row is used 4-5 times in the course of the test. There are 2 columns in the sheet.) When I run this in a load test with 1 user, it works fine. When I run it with 10 users at constant load, only about 25% of the tests are completed successfully. Could this be because the users are simultaneously trying to access the same Excel file and running into conflicts Or it might go like this: user 1 accesses row 1, then user 2 goes to row 2, and when user 1 comes back he hits row 3 instead of row 1 again. Another one of my webtests worked great with 10 concurrent users. This test only accesses the data source once per test, which is why I'm thinking there might be some ...Show All

• Visual Basic OCR - Optical Character Recognition

• Game Technologies: DirectX, XNA, XACT, etc. Locking of Managed Texture

  I'm currently developing an application which will use managed textures. Part of the code needs to create the texture data in a seperate thread. I will be locking the texture and passing the data pointer to a function. My question is will the video memory texture continue to render while the texture is locked Or should I copy out the existing data to a temp buffer for editing, then copy it back into the managed texture GrkEngineer Vite Falcon wrote: "I will be locking the texture and passing the data pointer to a function." I believe that u cannot lock a managed texture. Try using texture created in system memory. This is incorrect. All textures are lockable except those in D3DPOOL_ ...Show All

• Visual Studio Express Editions Can we redistribute VB express on our product CD?

  I know SQL Server Express can be redistributed with applications. I'm wondering if there is a way to license VB Express to redistribute with our application I don't think you will get legal hassles for doing so: you aren't exactly 'distributing' it, even though legally it's not right. I suppose theoretically, you could download another version and transfer the license to the person you are giving it to - it appears to be allowable, but I think you start getting into a gray area. Professionally, I wouldn't do it. ...Show All

• Visual Basic Formula construction

  I have a big problem here, I am writing an application that requires that the user have the ability to construct their own pricing formula for different items and have managed to store that formula in the database, the problem is... How can I read a resulting formula string as a formula I.e: (BuyingPrice * (100 + VATpercent) + 10) BuyingPrice = 40 VATpercent = 17.5 I can return the string "40/100*(100+17.5)+10" but can't find a way to process it and return the result (57). Any ideas will be greatly appreciated guys. The following is the VB implementation of this code, you'll need to add the reference to Microsoft.jscript.dll and there is a obselete warning which is generated fo ...Show All

• Windows Live Developer Forums Virtual Earth is so slow!

  Am I crazy, or is VE tremendously slower than it's competitor, Google Local As a Microsoft developer I am all for evangelizing the Live platform. However every time I tell people about the cool features in Virtual Earth, they all inevitably come back saying they were frustrated with the very slow performance and preferred to keep using Google Local. Is anyone else finding this Well, some of what you're saying might be true (about the caching). However, isn't it the job of the VE team to make sure the application's user experience is as good (or better) than the competition I told some friends of mine to mind their browser's settings for caching and, though it made some difference in perceptions, ...Show All
