• Windows Forms ListBox Drag-n-Drop Change Background Color of just one item

  Is there a way to change the background color of just one item in a listbox and still allow drag-n-drop In my code I am using a list where there is only one entry that can be TRUE (or activated) and I would like to change it's background color in the listbox. I want to change the item once the user selects another item as the activated one. Here is a example: the following DrawItem event handler that will put a yellow background on the second item. Set the DrawMode to OwnerDrawFixed and do something similar in your DrawItem event-handler. Hope this helps.

• SQL Server Rushi Activated Stored Proc blocking?

  Hi There I was wondering, i have experienced alot of stored procedure blocking where you have a stored procedure that get executed very frequently and is complex, when the sp has to recompile it is locked and cannot be executed by other processes. How will this work with an activated stored procedure, our activated stored procedure will probably not be too complex but it may exec complex ones base on the message type. Now lets say that a message is recieved by the activated sp he in turn executes a complex sp to process the message this causes the complex sp to recompile, during this time another activated sp is spawned by the queue with the same message type he execs the same complex sp that is busy recompiling, i presume that th ...Show All

• .NET Development Executing query with parameters in VB

  I appologize in advance if this question seems simplistic, but I'm fairly new to the whole data access thing. I have an access database witha query that requires a text parameter. I put it as a query into the tabel adapter for the table it went with and it gave me the error "unable to parse query text." The query work just fine in access, but for some reason VB does not like the PARAMETERS section. I want a query that requires a paramater (the name of a person) and retireves an integer value for that person in the database so I can store it in a variable. Basically how do I do this: PARAMETERS [Person] Text ( 255 ); SELECT [Table].Value FROM [Table] WHERE [Table].Person=[Person]; In Visual Basic ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 360 controller

  Hi there, Quick question about the 360 controller. Are there drivers that I need to install When I plug it into my machine it does not find drivers. Or can I not use it on my PC Thanks! I didn't get a CD with my wired controller (came with Xbox), but I just plugged it in, and Windows detected it and installed the drivers (might've connected to Windows Update for that). I didn't download or install anything, it was seamless :-) ...Show All

• Windows Forms problem with dates

  Hi again people i have this problem with the subtraction of dates used in my program. What i am trying to do is find the difference between two dates in the format of 25.5.2007 for example. The 2 dates are taken from a database and displayed in textboxes. If TextBox1 contains the above date 25.5.2007 and TextBox2 contains (lets say) 27.05.2007 the difference is 2 days but i cannot display this result in a third TextBox.

• Visual C# Unable to delete folder - being used by another process

  When I try to delete a directory I get an IOException because it is being used by another process. The only process that is using it is the one trying to delete it. To prove this I created a folder and added a txt file to it. I started the app, used an OpenFileDialog object to get the string of the selected file. I then try to delete the file but get the exception - I also get the error if I try to delete the file through Windows Explorer. When I close the app I can delete the directory in windows explorer. I don't understand why this is happening as I have disposed of the object. Is the OS holding onto something that I need to clean up Here is a simple example of the problem. try { OpenFileDialog openFileDialog1 = new ...Show All

• Connected Services Framework Is CSF Mature? Does it support other industries?

  We are a major media/content company, which offers content through cable, broadband, web, mobile device and print.   We are thinking about implementing CSF.   Is CSF ready for a non-telecom company Everything I read is telecom centric.   We do have many disparate systems that generate content that we need to merge into many different interfaces.   We currently do not have many media partners but this could change over the next year.   We currently do not have much of a BSS/OSS backend, or any clearinghouse operations.   We currently do not charge for our content.   We are   making limited use of web services, could we just continue doing our SOA that way. ...Show All

• Software Development for Windows Vista Endless state workflow, performance problem, Very common problem in real system

  We use state WF to handle our order processing. Usually an order has 5 states: (1)Script (2)Approved (3)shipping (4)Closed (5)Canceled The following actions move the state transforming between the above states. Approve (1) a (2); undo approve (2) a (1);Cancel (1),(2) a (5); close (2),(3) a closed; undo close (4) a (3) Let’s have a look at action “undo close”. It exists in a real world system. Because user some time still need undo-close an closed order to ship again. (Maybe because he just regret). My question is: which one is completed state of this workflow (4) Closed or (5) Canceled It seems there are no completed state of this workflow. If so ,when can I delete the persistence state If I set closed-state( ...Show All
