• .NET Development passing Streams to a MarshalByRef object method

  I have a class that implements the following psuedo-code: public MyStreamReadWrite : MarshalByRefObject { public void ReadWrite(Stream inStream, Stream outStream); } I am hosting this class as a server-activated, SingleCall, object, listening on a Tcp channel. I want clients to be able to invoke the ReadWrite method on the server and pass open streams to files located on the client. I have made this work by doing the following: register a client (for MyStreamReadWrite) and service (for Stream) in the client app, both communicate via TCP on different ports. register a client (for Stream) and service (for MyStreamReadW ...Show All

• Windows Forms Master-Detail Comobox Databinding woes!

  Hi, Im having a problem with a master-detail pair of comboboxes that are bound to a dataset. Let me explain further.... the master combobox allows a user to select a city the detail combobox then displays all suburbs within that city and the user should select one of those. both of these combo's are bound to a single dataset containing the city and suburb tables which have a datarelation. this works fine the thing which has me stumped is that I bind the selectedvalue with the field in another dataset's table(Policyholder) but it seems to not work correctly the binding seems unsynchronized. when navigating amongst different policyholders the ...Show All

• Software Development for Windows Vista TransactionInDoubtException

  Source: System.Transactions.TransactionInDoubtException: mscorlib Text: The transaction is in doubt I'm getting the following error is a very specific circumstance and I don't understand why. I've got a single unavoidably long running transaction (~90mins) that I run from a .net component against a SQL Server 2000 database. If I invoke my component from MMC.exe (COM based root) I'll often (eventually) get the above error message. However, if I invoke the component from a .net based root application it always seems to run without a problem.

• Windows Forms Thread Question

  Hi folks, I've written a small app that processes a list of files in a copy operation. I put the function to do this into a thread so the GUI of my Form wouldn't freeze up during a copy operation. It all works well except that I need to figure out how to signal the GUI thread to update it contents based on the progress of the copy operation - it displays a progress bar and a filename filed that indicates the file it's currently copying. It doesn't need to do updates during a file-copy, just between files (it's ok if there are no updates when copying a large file). How can I get the file info to the GUI Thread so it can update its controls ...Show All

• SQL Server How Do I Start New SQL Server 2005 Database?

  I just installed SQl Server 2005 on my Windows XP Pro system. But I can't figure out how to start the Database Engine. In the MS SQL Server Management Studio I see one Database Engine, but not SQL Servers. If I do "Update Local Server Registration" nothing happens. If I do right-click "New Server Registration" I get a databse icon with a white open circle. If I the try "right-click, Connect, Object Explorer" I get "An error has occurred while establishing a connection to the server...". All this time the right Summary pane is showing "No Server Connection." The tutorials are no help and do ...Show All

• Visual Studio Team System July CTP install of VSTS - Source Control Plug in Missing, Team Explorer missing

  Hi everyone, I recently upgraded from the June CTP of VS2005 to the July CTP, both are the Team Suite edition. Now in my new installation, everything works, but there is no Team Explorer window, I cannot connect to a TFS server, and when I look for Source Control plug-in's, nothing is listed. I can't find any evidence of Team System. I verified over and over in the control panel that I do in fact have the Team Suite edition installed. Any ideas on what could have caused this The installation didn't report any problems. Thanks, Ryan You'll need beta 3, which was released yesterday and is in the process of making its way onto MSDN.   ...Show All

• Visual Studio Local help not available in VS2005 TS RC; please help.

  I am having a (for me) the serious problem that the local help in VS2005 does not display any .NET content. Using VS2005 TS RC1, but the same happend before with VS2005 b2. - only Help on Help and Refactor show up in the index. - dynamic help and F1 help with standard VB code give no results - in Tools, Options, Environment, Help, I have 'try local only' - I cannot use online help, because it's way too slow for me here I suspect that somewhere in some settings or registry the URL to the integration of the VS2005 MSDN help is broken.

• Visual Basic replace listbox item

  Help, I can't figure out how to replace an item a listbox.  I can delete the selected item and add the nw item but there has to be a better way Thanks  Something along these lines may help as it it will allow you to replace Full exact match items or partial matches in items and chnage either just the first occurence or all occurences. As its searching for string matches in the list and not specific index positions your unlikely to generate an exception if trying to reference a specific item in the list which doesn't exist.

• SQL Server My SSIS Presentation.

  I was demonstrating some of SSIS's capabilities to our Software Development Manager and VP of IS. (We are deciding which ETL tool to use for our DW project. So goes this project goes the house).They liked what they saw and were crazy over Fuzzy lookup but commented that SSIS seems very much oriented toward the programmer side of the house. It was, maybe, not the best tool for the Business analysts who are working closely with us on this project. Any comments on their comment I wonder if SSIS "data source views" (which I haven't looked at at all) address their concerns Barkingdog SSIS ...Show All
