• Visual Studio 2008 (Pre-release) Child table not updating correctly?

  I have a person object, which has via a foreign key an address table attached to it in the LINQ designer. The address table has an addresstype which comes from a types table via a Foreign Key as well. When I create an instance of a person, and check the first address typeID I get a value of 4. Via my interface I change the value to 6 (a valid value in the types table), I can query the Address object and it will tell me it's set to 6. However, once I commit the changes via DBContext.SubmitChanges() the value rolls back to 4 in my local instance. I see not Exceptions being thrown.. and I'm just wondering if there is a bug somewhere in LINQ that isn't allowing the sub-tables for a given object to be updated properly Thanks. Jim ...Show All

• .NET Development Browse image's pixel

  Hi, I have to get the value of each pixel of an image to do some comparaison. I used the class Bitmap and i loaded a 800x600 image. It takes me 20s to browse all pixel. (i used the method getpixel in a double for statement) I want to know if there is a class, or an other method to do this faster (around 1s would be perfect) Thanks David Unfortunately J# doesn’t support unsafe code on its own... is there any chance that you could build a C# class (in a separate assembly) to do the unsafe work you need and then access it from your J# code ...Show All

• .NET Development Loading an Xml Document from a string variable

  My application saves an entire Xml document content in a database field declared as Nvarchar(MAX). I attempt to a load a new Xml document using the string stored in a database. The field containing the Xml string is returned by a stored procedure: string xmlField = (string)returnedData["dbXmlField"]; XmlDocument xdDoc = new XmlDocument(); xdDoc.Load(xmlField) xdDoc.Save("C:\Test.Xml") If I attempt to save the Xml document (xdDoc) I come up with ' Unrecognized escape sequence ' error message. None of the XPath queries work either. The reason for this problem (I suspect) is that all doubles quotes in the string have been escaped by "\" such as: "< xml version=\"1.0\" encod ...Show All

• Visual Basic Please make the VB.NET class public

  Hi All, I have a peculiar kind of issue after converting VC and VB code from Visual studio 6.0 to Visual Studio 2005. We have the business logic in the VC code which uses the ATL framework and implements a COM server. VB code gives the GUI part of the project, For reporting custom errors like invalid login, we use AtlReportError method to report error from the VC code side. While utilising the built VC dlls(unmanaged code), using VB 6.0 applications, we get the Error message text( like in the case of failed login), exactly as we require. But while utilising the VC dlls in a VB 2005 application, instead of getting a error message we see "Exception from HRESULT : 0x8004B411". I do not know the reason cause for dis ...Show All

Note: there should not be difference in the visibility of items . thnaks and regards ranadheer Hi, There are multiple possibilities. You could keep track of the items from the registry by using an external data structure: List< string > m_fromRegistry = new List< string >(); if (m_fromRegistry.Contains( listbox.SelectedItem ) ) { //from registry } else { //not from reg } You could also create a ListBoxItem class: class ListBoxItem { private strin ...Show All

• SQL Server Use an ActiveX module from a view/stored procedure?

  I was wondering if it is possible to use an ActiveX module from a stored procedure or view I have a table that contains some biochemistry, in particular, glucose and insulin as floating-point values.  I have an ActiveX module (as a DLL) that takes these two values and returns some measures of insulin resistance.  (I didn't write the module - it is available (without source code) from a university). The university provided a spreadsheet that does what I want to do.  I am wondering if I can use the ActiveX module and the function in the spreadsheet in a view in my database instead. Here's how you'd convert glucose and insulin in the spreadsheet: =HOMA2_Insulin(A1,B1) And here's the source code of the function th ...Show All
