• Software Development for Windows Vista Problems with state persistence and timer services

  Hi, I've experimented with adding the SQL state, timer and tracking services to the Lab1 sample step 4 (the expense report approval workflow). The tracking service works fine, but it seems that the state and timer services get the engine stuck on the ListenForManagerApproval activity. If I disable the state and timer services the workflow unfolds as expected. I use the (really cool) Workflow Monitor sample to view the results, and the progress is evident every time: With the state and/or timer service enabled, the flow gets stuck on ListenForManagerApproval  and then after a while the workflow gets the status "aborted". Any ideas why ...Show All

• Visual Basic sharing data

  Howdy, i want to have 2 or more ComboBox's sharing the same pool of data. ie i dont want to have to retype the whole lot 4 or five times, the data will contains peoples names. I have played around a little by having a MS Access Table with a list of names, but this seems inefficient. I also want to be able to ADD more names to this list by pressing a "button" etc. Any help would be appreciated.

• Visual Studio Really Frustrated With VS 2005

  I posted earlier about the fact you cannot get a copy of VS 2005 Pro even though the "launch" was 11/7. I have a Windows app I built using the VS 2005 Beta 2 that I need to update but since I downloaded the new Express editions (thinking they would work - wrong!) all the Beta 2 stuff is gone. OK, I went to my other system (Win XP SP2) and figured I'd install the VS 2005 Beta 2 there and use that until someone decides to "really" release VS 2005 Pro. No Joy. The install completed saying that it couldn't install all componets - it listed some like J# (which I never use) as failed installs. I deided to do a Repair/Reinstall - that al ...Show All

• .NET Development Query with Distinc Values

  Hi, Another problem, hehe.  I have an orders table with order_number, customer, item_number as composite primary key.  The table also has date_of_order and quantity.

• SQL Server Server: Msg 107 - The column prefix xx does not match with a table name or alias name used in the query

  Can anyone help me with why SQL server returns this error when executing the following query. I have read the online help on this and I am correctly using the alias in the subquery. The error is caused by the reference to the table alias FD in the subquery for fundvalues which gives me reason to believe that the subquery is being parsed or evaluated before the outer query. I don't know how to avoid this behaviour and I do not want to have to rewrite the process completely. The error is returned both when executed through the query analyzer and also when executed through the vb program. ( Note : This is a subsection of a much large ...Show All

• Visual C++ Poor Program Design?

  Hi Griffonbait! My experience with Borland C++ Builder is that BCB puts a declaration in the form's header file and opens up the coding window in the .cpp file ready for coding. My understanding of programming, and the way I have taught it, is that the header file is primarily for declarations not for a project's ("solution" as VC++ calls it) code. 1. Headers files are not needed for OOP-Design 2. The reason why the implementation of the managed-windows-forms C++/CLI is in the header file is, that the windows-forms designer can work probably (that means you can either change in the designer or ...Show All

• SQL Server Report Models using Islookup and expandinline
