• Software Development for Windows Vista CallExternalMethod in Code-Only and Code-Beside Workflows

  I have created two identical workflows that use a CallExternalMethod activity. I'm using .NET 3.0. One workflow is code-only and the other is code-beside. When I configure the CallExternalMethod activity, I see that the Data field in the Properties pane works differently for the two workflows. On the code-only workflow I can specify a member of my workflow class as the data to be passed. I see "Name" and "Path" sub-fields in the Properties pane. On the code-beside workflow I cannot seem to specify a member of my workflow class as the Data to be sent. Also, I do not see the Name and Path sub-fields in the Properties pane. I have checked the help and searched the forums and I can't find any documentation fo ...Show All

• Software Development for Windows Vista Standard User Analyzer causes COM and ActiveX to fail

  We have a legacy application programmed in C++ and MFC that runs on Windows 2000 and XP but has problems with COM and ActiveX when run on VISTA. This app is built with Visual Studio 2003. I remotely debugged this app running on Vista from my development machine and found that the COM and ActiveX problems is the app trying to instantiate the COM components but they return E_ACCESSDENIED. I have checked the following: 1. The COM components on both my development machine (XP) and the test machine (VISTA) have the same ACL’s. 2. The access denied problem occurs if I am logged into the test machine (VISTA) as a local user or an administrator (Admin Approval Mode). 3. I added: HRESULT hr ...Show All

• Windows Forms Implicit Error Provider

  Is there an implicit error provider on every windows form and user control I am trying to understand how .NET knows to show the default error provider while binding to objects that implement IDataErrorInfo, without us having to explicitly create an error provider. Is this default error provider accessible from code Thanks, Naveen System.Data.DataRowView implements IDataErrorInfo. The DataGrid and DataGridView controls use that interface in their Paint methods and display an "error" bitmap and initialize a tooltip if the row has an error. ErrorProvider is not involved. ...Show All

• Software Development for Windows Vista TransactionScopeOption.Suppress questions

  I know you can use Suppress to exclude operations from an ambient transaction. What happens if there is no ambient transaction present Does any sort of transaction get created Will Suppress override a Required or RequiresNew further down in the call stack Or will each be treated as an atomic transaction, since there is no ambient present due to the Suppress Do you need to call Scope.Complete() at the end of a Suppress scope Assuming you understand the logical implications of doing so in terms of data concurrency, is there any sort of overhead in wrapping all your read-only DAL methods in a Suppress scope Thanks! 1. No, a transaction will not be created in this case. 2. Suppress will suppress the ...Show All

• Software Development for Windows Vista ASP.NET And a State Machine Workflow

  I recently read the MSDN magazine article, Windows Workflow Foundation, Part 2 (http://msdn.microsoft.com/msdnmag/issues/06/04/CuttingEdge/), where Dino Esposito demonstrates how to work with workflows in ASP.NET. Dinos' demonstration provides a helpful solution to working with Sequential workflows; however, it left me a little confused with how to work with a State Machine workflow. In the article, Dino demonstrates how to pass parameters to a Sequential workflow by using a Dictionary object, which is then passed as a parameter to the CreateWorkflow() method. The problem is that State Machine workflows pass parameters through event arguments. Using the OrderWorkflows (beta 2, lab 4) example as a starting point, is it pos ...Show All

• .NET Development Microsoft.Office.Interop.Excel.dll

  Hi again I am still having problems with this Excel Interop ... I did a little sample application. It just opens a excel file and than closes it.

• .NET Development Xpath Expression with XpathNavigator.Select vs XmlDocument.SelectSingleNode

  Hi. I have an xml file with proper namespace and schema. I have an xpath expression that I have tested on the document in xmlspy (xpath 1.0 or 2.0) which returns a single node element. If I load the file into an XmlDocument and apply the expression with SelectSingleNode, I get the proper element value back. If I use XpathNavigator.Select on this file, which I understand, returns a node set, (even though the expression can only match a single node), I get the inner xml of all the nodes in the file (3 values). I am properly using the XmlNamespaceManager in each case. With the Xpath navigator, I have moved to root initially, before doing the select. Does anyone have any ideas why the XpathNavigator is returning strange resu ...Show All

• SQL Server Excel Destination appends the excel file everytime a package is executed

  i have an SSIS package that exports to an excel file. This works fine. the problem is that it appends the data instead of overwriting the file. Is there any way to overwrite the file like you can with a flat file I have to email the file everyweek and don't want to have to clear it out manually. Any help would be appreciated Pamela, You could also use a Execute SQL task to create a new excel file on every execution of the package. I have posted an step by step guide on that: http://rafael-salas.blogspot.com/2006/12/import-header-line-tables-_116683388696570741.html I hope you find it helpful ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. from Static to Instances?

  Hi, I have come to a point where I want to change my code from using alot of static stuff to use instances instead. I read the thread on Best coding practices with ContentManager and GraphicsDeviceManager on this forum and decided that it's time to rewrite alot of code.
