• Visual C# Refresh Start Menu

  Hi Everone, I'm going nuts on this one!! I'm trying to refresh the Start Menu and the Favorites folder after deleted the MenuOrder key in the registry, forcing it to reorder folders and icons alphabetically. The code below really doesn't do anything and I can't figure out how to take next troubleshooting step. Could some one please help a poor man ;-) using System; using System.Collections.Generic; using System.Text; using System.Runtime.InteropServices; namespace ReOrder { class Program { [ Flags ] public enum SHCNE : uint { SHCNE_RENAMEITEM = 0x00000001, SHCNE_CREATE = ...Show All

• Windows Forms Design Time Reflection

  Hello. I'm creating a custom control with desing time support. For a property MyItems that is a collection of BaseItem's, I need to allow the user to add as many items he wish on a form I created (all in design time). The problem: I have a number of classes that derived from BaseItem, and I want that the user will be able to select from a combobox all optional elements by using reflection of some sort, so that we I create a new BaseItem derived class, I don't want to change the combobox. How can I do it Hey Eli, You can iterate over all the types in an assembly and check inheritance and all with IsAssignableFrom and IsSu ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Converting a ray into object space

  Hello, I have been stuck on trying to convert a ray into object space, for simple collision detection, I have tried multiplying the coordinates of the ray with the objects inverse matrix ( x = x*_11 + y*_12 + z*_13, y = etc..) but that does not seem to work. There should not be any problems with detecting the collision as I am usuing the D3DXIntersect() function with this ray and the objects mesh. The current code I am using is: D3DXVECTOR3 vPos = pGlobal_Game->pData->objData[iID].Pos3d - pGlobal_Game->pData->objData .Pos3d , vDirPos = pos3d - pGlobal_Game->pData->objData .Pos3d, vDir; iID being for the object th ...Show All

• SQL Server Starting job on remote server

  I've read that you can run a job on another server as long as you have a link server from the source to the destination server. I've search for hours online and read nearly everything in SQL Server Books Online pertaining to the sp_start_job function without success. I can't find one example on how to accomplish this. I want to run a job called Job1 on Server1 from Server2 with a link server on Server2 to Server1 called ServerConn. The link server works fine grabbing data from Server1; so I know the link server works. I am having problems on the server part of the sp_start_job function. use msdb exec sp_start_job @job_name = ' ...Show All

• Windows Forms Determine Source Control of Drag Drop Operation

  Hello: I have a MainForm with 2 treeViews and 1 listView. I allow drags from treeView1 and the listView1. TreeView2 only allow drops. I would like to determine the source control from where the drag started in the DragDrop eventhandler. Is this possible basically: after drop if treeView1 is the sourceControl > do this if listView2 is the sourceControl > do this Thanks in advance. {C# VS2005} I found a little work around but I would still like to know if there is a method to do a definite test of who the originating control is.

• Visual Studio 2008 (Pre-release) Use of unassigned local variable 'fact'

  We can't write this: Func<Decimal, Decimal> fact = n => n == 0 1 : n * fact(n-1); because the compiler says: "Use of unassigned local variable 'fact'". Should it be possible I guess. Currently we have to write this instead: Func<Decimal, Decimal> fact = null; fact = n => n == 0 1 : n * fact(n-1); Then we are able to call fact(5). Single word - exceptions. Expression after equals sign can throw in middle of contruction while reference to fact was not assigned yet. ...Show All

• Visual Studio Team System Connecting to a datasource that is a very, very large database with many tables

  In our setup we would like to connect to an IBM DB2 datasource. We do have an OleDB for DB2 installed and we can connect just fine. But then the datasource connection tool goes after the DB2 datadictionary to show all the tables and it dies after having been busy with this for a really long time. The problem is that our data dictionary contains all the tables in all the databases and we have easily several thousand tables per database. So this is not working. I know my database name and I know my database table, but I have no way of setting this up through the "Add Data Source" facility. Is there another way I can do this ...Show All

• .NET Development Creating Lazy Collections

  I'm working on writing generic lazy collections, but I'm stuck on how to best do this. It seems inheriting from List<> or Dictionary<> is not a good option, as none of the relevant methods are virtual. I don't see any abstract generic collections, so it seems that my best bet is to wrap a List<> or Dictionary<> in my LazyList and LazyDictionary, while implementing the same interfaces that bout List<> and Dictionary<> implement. Does this make sense, or am I missing something Google didn't turn up much of anything in terms of code examples; neither did codefetch{. Have a ...Show All
