• Visual C++ Problem using #import with ADODB in VS2005

  I have a VS2003 project that I am migrating to VS2005. It currently compiles just fine under VS2003, but when I try to compile it under VS2005, I get a whole slew of C2327 errors. The root cause appears to be the different way that VS2005 handles nested classes. However, the code that the compiler is having a problem with is generated by VS itself as a result of a #import: #import "C:\Program Files\Common Files\System\ado\msado25.tlb" rename( "EOF" , "adoEOF" ) rename( "BOF" , "adoBOF" ) rename_namespace( "ADODB" ) An example of the error that I receive is: error C2327: 'ADODB::_ADO::Properties' : is not a type name, static, or enumerator Has anyone else encoun ...Show All

• SQL Server How to build this expression?

  Greetings friends, I have the following T-SQL CASE statement. I've spent the last 10 minutes trying to convert it to an expression in my derived column component but to no avail. case when f.etypeid < 10 then '000' + cast(f.etypeid as varchar) when f.etypeid > 10 and f.etypeid < 100 then '00' + cast(f.etypeid as varchar) else '0' + cast(f.etypeid as varchar) end Many thanks for your help in advance. Hi again guys, Finally I managed to work it out. Silly me! The solution to the above is as follows : etypeid < 10 "000" + (dt_str,1,1252)etypeid : etypeid > 10 && etypeid < 100 "00" + (dt_str,2,1252)etypeid : "0" + (dt_str,3,1252)etype ...Show All

• Windows Live Developer Forums Is anyone buying VE transactions?

  Hello, I posted something similar to this earlier but no one responded. We want to transition more of our maps to VE but we're not sure how to merge VE into our existing MWS account. Is there something programmatic that we need to do (i.e. proxy the calls through our server so we can affix an account ID to the requests) Currently, we pay about $500 per month for MWS services and just use VE under the "5000 transactions or less per day" for a few of our maps. An associated question is, does MWS dish up the same map style as VE (tiling, etc.) From what I can see, it doesn't. Thanks, Jeff I'm still waiting Jeff. But I have a very different need in my licensing. If you're a current MapPoint customer you should ...Show All

• SQL Server Copy database with encrypted column to new server and decrypt column there

  To do this successfully do I need to backup the Service master, Database master, and database itself from the the Source server, then restore all three of them on the destination server (I'm concerned that restoring the source Service Master key to a new target server with an existing sql 2005 install will screw things up big time.) TIA, Barkingdog It's actually a little easier than that. All you have to do is restore the database and then restore the encryption between the SMK and the DBMK. The database master key should already be in the database so after that you just need to associate the DBMK with the new server's service master key. After restore, you will need to: 1) use <data ...Show All

• Visual Basic Passing things from Form1 to Form2 and back

  Hi everyone ! Imagine this : I have 2 Forms: Form1 and Form2 Form1 is the startupform and holds a button, Button1 , to show Form 2. Code: Dim F2 As New Form2 Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click F2.Show() End Sub On Button1_Click an new Form2 is shown. Form2 holds a button wich should change the text of Form1: Code: Dim F1 As Form1 Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click F1.Text = "hello" End Sub This gives the result : Object reference not set to an instance of an object.

• Game Technologies: DirectX, XNA, XACT, etc. ContentManager questions about device resets

  I am trying to figure out exactly what the content manager does and does not do for you. Here's what I've found. The content manager caches resources http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=886913&SiteID=1 The content manager does not help you load resources in a background thread http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=966705&SiteID=1 And, from what I can tell, though I've not found anything very conclusive, the content manager will take care of device resets. I've not been able to get this to happen though. Right now, I can move my game from one monitor to another and a texure is invalidated.

• Visual C# help with structs and arrays

  Hello, I'm something of a C# neophyte, and I have the following problem. I'm trying to set up two arrays inside a struct: public struct Person { public int[] second; public int[,] response; } Then I want to declare the arrays, second = new int[actionwidth]; response = new int[actionwidth,actionwidth]; but then I get an error saying that response and second "do not exist in the current context". I presume this is because response and second are in the scope of Person. How can I declare these arrays Thanks for any advice. It would help if I knew what you're trying to do so I could have an idea of a possible implementation t ...Show All

• .NET Development disposing/freeing memory for image

  every few seconds (5) I recieve an image from a server. This works fast and well with wireless and usb connection, bluetooth is of course slower, i guess its advantage is that we can catch any possible errors.   now, when I recieve an image, I read the contents into a memory stream until an EOF flag is sent. This all works great. Once fully recieved, I raise an event from my thread (non UI) to the UI, which in turn, raises another event to another form (so UI -> UI). This final event in the UI (picture viewer) then calls a delegate method to show the image recieved by reading it from memorystream: public void DoShowImage( MemoryStream theMemStream) { if ( this .InvokeRequired) { DoHandleSho ...Show All
