• Visual C# DataTable.Select (string) problem

  I am trying to use DataTable.Select (string) to filter out rows on two columns: the first column is type string, the second: DateTime. This is how the string looks: string sql = "symbol = #" + ( string )arrL1[ii] + "# AND dateTime = #" + Convert.ToString (dated) + "#"; symbol is a column name of System.String Type and dateTime is a column name with DateTime Type; dated is a variable type DateTime with a specific date and time. I verified its value. It is a valid, non null value. I get this error: The string was not recognized as a valid DateTime Type There is an unknown word starting at index 0. In other words the first character is unacceptable. I tried to remove '#', then I replaced '#' with ...Show All

• Windows Forms User Control with radio button

  Hi, I have a user control having table layout (two column). One column has radio button and another column has text control.

• Software Development for Windows Vista CardSpace Use Case - Lost or Stolen Cards

  This may be in the documentation and I just have not found it yet. As we consider using Identity 2.0 for our IdM services (so we would be a relying party or resource website), we are reviewing our use cases that were based on the 1.0 model. We plan on supporting OpenId URLs and the self-asserted Cards in CardSpace from a client's machine. One of our analysts asked what happens in the case of lost or stolen Cards So the laptop is stolen or the hard drive crashes. With OpenId we don't see a lost or stolen problem as the OpenId is stored on a website. I suppose there is the possibility that that website would close its doors. We could see a client calling our support line and telling us they had lost their CardSpace on their Vista ...Show All

• Visual Studio Express Editions MSXML XMLReader trouble

  II have run into a problem in the following line of code. xmlReaderPtr->parse(_variant_t(&bstrDirectoryTreeXML); xmlReaderPtr is a 'ISAXXMLReader *' data type.  As best I can tell the parse function requires a 'const _variant_t&'.  bstrDirectoryTreeXML is a BSTR data type.  I checked on the MS website and it say's that the parse function can accept a VT_BSTR.  I don't really know what that means I took it to mean a variant with a BSTR inside but I guess I was wrong because that's what I sent it and it gave me an invalid argument exception.  If anybody can help me in any way please help I am stuck here. _variant_t dirXML = (bstr_t)bstrResponseText; hr = xmlR ...Show All

• Visual Studio Documenting overloaded methods and Sandcastle

  I'm a bit of a newbie using Sandcastle, so please bear with me. I'm at a lost. I cannot find out how to document the collection of overloaded methods. For instance. Say I have four overloaded Add() methods: public void Add( string name) public void Add(string name, Socket socket) public void Add( Socket socket, RobotPart robotpart) public void Add(string name, Socket socket, RobotPart robotpart) It looks to me as though Sandcastle, by default creates a folder for all of these Add() methods, and randomly chooses one of the headers as the folder name (again please bear with me about the names I am using) Now, within a summary tag for another method, say GetSomething(), I want to place a tag which wil ...Show All

• Windows Forms app control using only keyboard

  Hi! I'm working on an windows form application that has to be controlled only with keyboard. I have a form on which a have some controls (2 rows of 3 controls) similar to buttons. What i would like to do, is to move with cursor keys between these controls and when a cotrol is currently selected it should highlight and when i press enter it should execute a piece of code. The problem is that i can't capture the cursor keys. It seem that i can only move between controls by their tab property. It seems like the form is handling the cursor keys by it self Best regards, Nec Private Function FocusedControl () As Control Dim TheControl As Control = Nothing For Each c ...Show All

• Visual C# Method(new Object), when is the object released/disposed?

  Since there are quite a few .NET Framework methods that have a 'Method(new Object)' syntax, when is the Object get released/disposed How is the previous Object instance handled when you do this; Loop:   Method(new Object); EndLoop. Same question for 'Property = new Value' syntax. Loop:   Property = new Value; EndLoop. The object will go out of scope after the last reference to it in the called method. At this point it will be eligible for garbage collection, however there are no guarantees about when this will occur as it is not a deterministic process. The object will not be disposed even if it implements IDisposable as the Dispose() method is never called on it, however if it does ...Show All

• SQL Server Simple query chooses clustered index scan instead of clustered index seek

  the query: SELECT a . AssetGuid , a . Name , a . LocationGuid FROM Asset a WHERE a . AssociationGuid IN ( SELECT ada . DataAssociationGuid FROM AssociationDataAssociation ada WHERE ada . AssociationGuid = '568B40AD-5133-4237-9F3C-F8EA9D472662' ) takes 30-60 seconds to run on my machine, due to a clustered index scan on our an index on asset [about half a million rows].  For this particular association less than 50 rows are returned.  expanding the inner select into a list of guids the query runs instantly: SELECT a . AssetGuid , a . Name , a . LocationGuid FROM Asset a WHERE a . AssociationGuid IN ( '0F9C1654-9FAC-45FC-9997-5EBDAD21A4B4' , '52C616C0-C4C5-45F4-B691-7FA83462CA3 ...Show All
