• Visual C# Sharing variables between classes

  Hi all I have the following project.  I would like to have a common property across all classes, i.e. such as skin color in the example below.  Is there a better way of constructing this object and assign the skin color Thanks for the advice, Steve using System; using System.Windows.Forms;   namespace WindowsApplication1 {   public class Class1  {    public static void Main()   {    Person myPerson = new Person();    myPerson.SkinColor = "Purple";      myPerson.myArm.description();    myPerson.myLeg.description();   ...Show All

• Visual Studio Express Editions Database Update Allows Additions but not Deletions?

  Hi, I’ve created some code to add new rows to my database which works fine, and after restarting the program, all new rows are still there. (I’ve modified the database parameter from ‘Do not copy‘ to ‘Copy if newer’.) Another subroutine I’ve created removes certain rows. While the program is running this works fine! However, when I restart the program the deleted rows are back in the database! This seems really strange! I can add new rows which are updated to the database, but deleted rows are not being properly deleted from the database, because when I restart the program they are back. It seems the database is ...Show All

• Visual Studio Team System Web Test Unable to Record

  I have found an issue with the Visual Studio 2005 Web Test which is preventing me from recording any further scripts. Each time I attempt to record a new test it no longer records the URLs visited. The left had pane in IE normally displays information on the Web Test tool and information on URLs visited. This appears as just a grey panel – I’ve also noticed that the PC is running very slowly and the memory usage is maxing-out at 100%. (The PC I’m using is a P4 1.8GHz with 712MB RAM.) I have been able to record several tests in the last week without any issues and this problem has only just arisen. - Things I ...Show All

• Visual C++ VC8, Adding __event to non-CLR code gives error C2712

  In a non-CLR class I have a number of __events defined. When compiling the source code in which the corresponding header file has these __events, I receive the error: error C2712: Cannot use __try in functions that require object unwinding pointing to the last of the __event lines in my header file. When I look at the error message it says: "cannot use __try in functions that require object unwinding". Further it is mentioned that "object unwinding" means "destruction". Needless to say I am not using __try anywhere but perhaps the code being generated by the __event extended keyword is. I have no idea what the function that "requires object ...Show All

• Windows Forms How to improve Listbox performance in ADO.NET 2.0?

  I have a bunch of listboxes on my windows forms with a couple of thousand records in each one of them. It takes almost about a minute to load a form in .NET 1.1 We are migrating the application to .NET 2.0 and was wondering if there is any way to improve the performance in ADO.NET 2.0 so that the listboxes are loaded faster in .NET 2.0 I tried running speed test as per: http://msdn.microsoft.com/msdnmag/issues/05/11/DataPoints/default.aspx fig=true#fig6 and was really satisfied with the promising results. Please let me know if you have general tips / suggestions to improve performance of ADO.NET Windows Forms Application in g ...Show All

• Visual Basic VB6 keywords, language to VB.net

  VB6 Language reference provided all keyword data, language reference data, etc. sometimes with little code snippets. Where is there equivalent information on VB.net that is in simple format like that used for VB6. I find help in vb.net so confusing as to be worthless. Also where can one find an equivalency table VB6 to VB.net. For example, a VB6 keyword not covered in VB.net, should indicate a workaround. For example screen height in VB6 refers to the monitor screen, VB.net indicates an error with screen. Where are the workarounds This is an interesting discussion. The other day, I was looking up del ...Show All

• Visual C++ testing event == nullptr

  With the old syntax you had to test whether there was any handler connected to an event by writing   if (myevent != nullptr) myevent(this, myargs); With the new syntax you no longer have to perform the test, which is good, but what if I really want to know if there are handlers What would be the syntax then Chris. Hi Chris: the feeling of the C++/CLI design team was that an event is an abstraction of add, remove and raise and that users shouldn't really be peeking behind the curtain . If you really want this level of control then I would suggest that you use a raw delegate instead of an ...Show All

• SQL Server Formatting Job Step Commands

  When I create a script for a SQL Agent job I like to format the job step command with tab's and line-feeds using CHAR(9) and CHAR(13) respectively within a string of SQL.  This then gives me a nicely formatted string when you view the job through EM. If I view the same job through 2005 Management Studio the step commands that were so nicely formatted  in 2000 EM are now just one long line, wiht no formatting. Is there a way that I can format the step command string as I creat the job through my SQL script ...Show All

• Visual Basic VS 2005 seems unusable for large VB converted project. How do I turn off the background compiler.

  VS 2005 seems unusable for large VB converted project.  How do I turn off the background compiler. I have a fairly large project that I migrated from VB6 to VS2005.  This is the RTM version of VS2005.  There are many issues that I need to fix up in the code, but every time I change one line of code, my system runs 100% CPU for 30 seconds. This is not even close to usable.  You might think I have a slow machine, but I am running this in a P4 3.5 GHZ with 1GB of RAM, and a SATA 150 hard drive. I will be forced to abandon use of VS 2005 for this project unless I can find a work around for this issue. Please help! ...Show All

• Visual Studio 2008 (Pre-release) AddVisualChild question

  I have a design where I want to load a visual dynamically from an assembly (a plug-in system). I won't know which assembly or namespace ahead of time, so this has to happein in code-behind and not in xaml. I have created a class that derives from FrameworkElement called PluginHost. PluginHost loads the visual from the assembly and creates it just fine, but I can't figure out how to get the visual instance added to the PluginHost. AddVisualChild doesn't seem to do anything. VisualChildrenCount still shows zero and nothing appears after the call. Can someone help To add visuals to your class you need to ...Show All
