• .NET Development Send directly to MAC address over Ethernet

  I Need to connect to some hardware device (a lab instrument), which is connected via Ethernet to the PC and which has an unknown IP address or no IP address at all. This situation may occur, if the system is started up the first time and no DHCP server is on LAN. I thought it would be a good idea to implement some communication with ARP protocol, but I couldn’t find any .NET class helping me. I found a system DLL (iphlpapi.dll) which gets the MAC address from any client, if I know the IP address , but no method to send to a MAC address. My Questions: 1) Is there a way to communicate with ARP in .NET 2) Is there a plan B, which solves my pro ...Show All

• Software Development for Windows Vista Embedding Explorer window inside an application

  The Shell in Vista build 5270 is great: it lets the user sort and search/filter by metadata like keywords, rating, creation date, and an application can add custom metadata for new file types. It's so perfect for my app, I want to use the existing Explorer UI and not have to develop my own! Is there a way to use a Vista Explorer window as a control or otherwise use it as a child window inside my application Is it possible to change the look of it ("skin" it) in any way Opening up an old topic again. I have implemented the CLSID_ExplorerBrowser and have successfully made it look just ...Show All

• SQL Server Execute a SSIS master package through an ASP.NET web app

  I am trying to execute a SSIS package via a web application built in c#.  I found a sample to read the output of a data flow task, but I'm stuck.  If I build the command line syntax for the package, create a DtsConnection object and set the connection string to the syntax, what else do I need to do   Thanks. Clay Well, the critical step is to create a DtsCommand whose CommandText = the name of the DataReader Destination in the package, then to execute that command to retrieve the DataReader [contents].

• SQL Server ReportingService2005.CreateReport() warning...

  I am using Reporting Services 2005 on SQL Express with Advanced Services... I am dipping into the SOAP API and trying to add DataSources and Reports dynamically, as is how I would like to be able to deploy them... My problem is this: I have a shared datasource and a report that were deployed to the server via the 'Deploy' method in VSTS...I can access that report just fine, and it obviously uses the shared datasource... Next, I copy the .rdl file of the report I already deployed and give it another name ("NewReport.rdl"). What I want to do is add this report to the server (it's an exact copy of the functioning report wi ...Show All

• Visual Studio 2008 (Pre-release) DLINQ Queries and observations

  I have the following queries/Observations about DLINQ. 1. I could not find any direct way of handling many to many relations. Suppose if User and Role are related by a join table UserRole then I should be able to have a collection of Roles in User and vice versa. Which i think is not possible in DLINQ. (Please correct me if I am wrong) 2. State management is handle outside entities. In scenareos where a client grabs a entity from a WS , makes some changes and post it back to the ws for updation, how is the DLINQ framework handle optimistic locking Why can't state be maintained in the entity itself maybe by a base class, we already c ...Show All

• SQL Server oledb source issues with parameters

  Hi, I been having issues trying to use the OLE DB Source in the DataFlowTask.  If I use the SQL Command to build a SQL Statement, i.e. "select * from tablea a join tableb b on a.column1 = b.column1 where column2 = ", I can't get the query to parse and it won't allow me to set a value to the parameter.  It seems to be a bug as the only way I can see to get around it is to use a variable to place my sql statement into and use the "SQLCommand with Variable" option in the OLEDB Source.  This seems pretty clunky to me as I should be able to just put my select statement in the SQL Command window, right   Is this going to b ...Show All

• Windows Forms DataGridView Columns Changes Lost

  I am having a problem with changes that I make to the DataGridView columns using the Designer being lost. The DataGridView is bound to a binding source object and is not changed and no other changes are made to the data grid. The designer automatically regenerates the code sometime during a recompile and does not keep the changes that were previously made. I have not been able to pinpoint the exact sequence of events to consistently reproduce the problem. This problem is preventing me from relying on the Designer to setup my columns. Has anyone experienced this behavior Thanks in advance Jorge ...Show All

• Windows Forms How do I get the dimensions of the TRUE Drawable area of a form?

  I am writing a DirectX app that uses windows form menus and controls. I want to get the TRUE drawable area of a form excluding menus and things like panels and other controls like that that cannot be drawn on.. I know about the Form.ClientSize property but that does not take into account any menus/status bars within the form. Only the size of the window minus the borders. I thought it wasn't possible for the Form to directly know its drawable area without manually calculating it until I started using the MouseEnter and MouseLeave events. These events trigger when the mouse leave the TRUE drawable area (eg if my mouse goes over them men ...Show All
