• .NET Development Object List in C#

  Hello, coming from C++ and using a lot of MFC stuff, I wonder what object exists in C# which does the job of a CObList in C++ I mean being serializable and being able to stock different types of runtime class objects. Thanks for any further information ... Best regards MMM Binary Serialization is effeicient way to serialize some object. Its fast and a serialized object takes lesser space in memory on the other hand XMl Serialization / Soap Serialization takes more memory and is not much efficient like Binary Serialization. One other thing, Binary Serialization is preferred one your system is .Net based, both serialization and deserialization because you not to have same assembly to serialize and deserialize the obje ...Show All

• Visual Studio Express Editions Issues using the keydown event

  I am new to visual basic 2005 Express Edition (I learned in Visual Basic 6.0). I have been creating a tetris game for fun to learn the new modifications on the visual basic language. I have run into a problem concerning how to use the key down event to register when the user presses an arrow key. I used the help function and came up with this: Private Sub frmTetris_KeyDown( ByVal sender As Object , ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me .KeyDown Select Case e.KeyCode Case keys.right etc etc. End Case End Sub (I left code out) I cannot get it to respond to my keystrokes, and i cannot figure out why. At one point it did respond, but i corrected an error in my ...Show All

• .NET Development .NET security and network drives - how to turn it OFF?

  How do I TURN OFF .NET security so I can run applications on network drives without getting SecurityException's I dont think you can really - you may need to strong name your assemblies to be trusted to run (I think) Take a look at this: http://west-wind.com/weblog/posts/275.aspx http://support.microsoft.com/ kbid=832742 (the last part will be the most useful) http://www.c-sharpcorner.com/Code/2003/March/StrongNamedAssemblies.asp http://msdn2.microsoft.com/en-us/library/zdc263t0.aspx http://msdn.microsoft.com/library/default.asp url=/library/en-us/dv_vstechart/html/vbtchSecurityConcernsForVisualBasicNETProgrammers.asp ...Show All

• .NET Development Share the first authenticated Token

  Hi,all I have got an authenticated UserNameToken using UserNamePasswordValidator.Also I've already established the security conversation. My answer is that how can all of my web servises can share this Token, in other words every single service needn't be validated at the first time. Thank you in advance! Hi Noel, Are you using WCF or WSE . Both frameworks keep the authenticated SecureContextToken in the service proxy instance (In WCF, the proxy instance is the channel). So, if you want to reuse the same token, the easiest way is to reuse the same proxy instance. Reusing the token in different proxy instances requires more work, and both framework have completely different ways to impleme ...Show All

• Visual Studio Express Editions Compiling Boost in VC++ 6.0

  I would like to know how to compile Boost Library in VC++ as there are only header files(.h files) provided and no implementation files (.cpp files). As almost all of the Boost library is template based it is usually just defined in header files. So all you need to do is to just include the header file you need. Note: trying to use Boost with Visual C++ 6.0 can be a real pain as the support for templates in Visual C++ 6.0 is poor. If you wish to use Boost I would upgrade to at least Visual C++ .NET 2003. ...Show All

• SQL Server How to transfer or export dbf file to SQL server 2005 express edition?

Like polling every 5 to 10 seconds transfer data to sql server 2005 ex edition. Is it recommend to do it visual basic program , how to do it. pls help Hi Stephen, In SQL 2005 you can set up a linked server, a stored procedure, and a recurring job to run the stored procedure. I'm assuming you want to import only new or changed rows from the DBF and the stored procedure would allow you to do this before you update your main table. I don't usually work with SQL Express, and I see that you can set up a linked server, but SQL Server Agent is not available to s ...Show All

• Visual FoxPro rounding bug in vfp8?

  I have found what seems to be a rounding bug in VFP8. Any ideas how I can get around this please I was doing some testing when I found that I was a penny out on digging deeper it seems that when lnValue = 0.57500000000000, Round(lnValue,2) gives 0.57!!!!! when it should give 0.58. This is causing my validation to fail. Is this a bug The strange thing is that Round(.575000000000,2) gives 0.58 but the extra 0's in the scenario above are causing the difference. Thank you Andy for your full explanation and suggestions. In case anyone else is following this thread I think In practice you might be able to get away with shortening that slightly by removing the round altogether as the STR & VAL combi ...Show All

• Visual C# TreeView.NodeMouseHover question

  This is really puzzling. I copied this code from the VS Online Help. It will display the TreeView.Node Path when the mouse hovers over a node. But, the display won't appear until I move the cursor over another node, when I do that , the information shown is for the first node. For example, my TreeView is a list of members in a group as shown below. When I hover the mouse over a node, nothing happens until I click then move the mouse to another node. In this case, I've just clicked on node "C" to open it and then moved the cursor to hover over node "B"; when that happens, the information for node "C" is displayed. What did I miss from the Online Help site + Name List + A + B - C ...Show All
