• .NET Development another timer question

  Hey, I'm developing a program to calculate satellite orbits, and some calculations need to be done each second, others each day. For that I'm using System.Timers.Timer class. This program is going to be running for a long time, sometimes even months. Question: isn't this a bit dangerous I mean, having a timer running for this long time always counting up Any suggestions Thanks I believe you may find some of your objects would be disposed if it is not being used but as well as this, having a timer interval set to every second (1000 ms) would be really bad. If you must, try to make sure the timer interval is set to the true interval you require as close as possible. ...Show All

• Visual Studio Tools for Office Problems with VSTO2005 on Vista

  hi, I just installed VSTO2005 (English version out of the box) + SE (download) on Windows Vista Business (german version). Now I have the following problems: 1) The language of the menu-items in the VSTO-IDE is mixed (english/german). For example I get a "File/Open" menu-item (in English) and a "File/Schliesen" menu-item ("Schliesen" is the german word for "Close"). 2) The local help (although successfully installed) cannot be accessed in the VS-IDE (is always empty). I have seen on Microsoft websites, that there exists a VS2005 SP1 and a VS2005 SP1 Update for Vista (Beta). BUT as VSTO2005 is NOT listed as a valid VS-version for VS2005 SP1, I cannot install it. And therefore I cannot install th ...Show All

• Visual Studio Team System Is Team System just for .NET developers?

  We have both .NET developers, and developers using other platforms at our company. Will the Team System work for everyone, or is it primarily for .NET/Visual Studio developers I haven't been able to locate any specific IDE requirements or info on what development platforms are supported. Bob, Team System is made up of serveral parts. A lot of functionality has been added to Visual Studio 2005 in the various flavours of the Visual Studio Team System. However, the glue that holds the whole team development togther is Visual Studio Team Foundation Server (TFS). As stated, TFS offers services that are useful for collaborative development i.e. Version Control, Work Item Tracking (work items being bugs, requirem ...Show All

• Visual Studio How to add a custom rule that listens on "delete" events?

  How can I add a custom rule (or similar mechanism) that fires custom logic in case I delete a class in the domain model In my example I have a domain model from which I create various ASPs and C# classes (for each domain class various implementation artifacts are being generated). For consistency reasons, I would like to add a “delete” event listener in the domain model. So, whenever a domain class is deleted, I would like to delete the derived implementation artifacts. Traceability is not the issue, only having a listener to a “delete” event. How would I do that Thanks, Alex I rule gets fired after modelelement/connector is deleted, is there anyway to capture it before it is deleted and get all the ...Show All

• SQL Server Relationship between t-Sql and "Set Theory"

  I have always heard that much of t-sql is based on "set theory". I had Set theory in high school and I remember it as being simple Unions, Intersections, Differences of Sets. By a Set I mean a collection such as {2,5,7,8,9, ...) That could well described a single row in a table. By unioning several of these rows we could end up with a table. But how does that relate to t-sql such as select * from <table name> Where <condition 1> Is it simply that the result returned by the query is a Set (if so, a Set is simply being used as a synonym for a Collection. No set theory involved.) TIA, barkingdog This is quite a large subject =;o) Perhaps the best way is ...Show All

• Visual Basic Missing Items....

  Hello everyone, I am hoping someone can help me. I have been working on a small project in VB.Net 2003 and I was doing a good bit of Cut/Copy and pasting some text boxes, labels, etc. Anyway I suddenly have my items on another form with names like TextBox1 and Label3. And the original items are still showing on my Properties Drop down, but they are no where that I can find. How can I get these orphaned items out of the project so I can rename my items correctly Has anyone ever seen this before Thanks man, I really had tried that but I didn't close out and open it back up. I think that was the key because when I did that extra step this time it worked like a charm! ...Show All
