• Visual C# Callback from C++ .dll fails with "The memory could not be written"

  Hi, I'm having serious problems getting code that used to work in Visual Studio 2003, to work in .NET 3.0. I'm using Microsoft Expression Interactive Designer, but I figure my question is not really related to that product at all. I have a dll that controls a USB device (an ArtLebedev Mini 3). I can call bits of the dll fine and correctly set up my USB device. The problem is using a method within my c# code for the callback when a button on the device is pressed. After setting up the callback, pressing a button on the USB device causes the whole application to crash with a "The memory could not be written" error. Which i'm assuming means the dll is trying to call my method in c# but for some reason can't (memory address has chang ...Show All

• SQL Server How to control caption for the bit attribute?

  Hi Gurus, Have anybody idea how to control the caption of bit attribute The default is True/False. 1. How to force the AS to show Y/N or Yes/Now t . 2. How to force the AS to show localized bool string (Wahr/Falsch, / ). I can create table like ID Caption 0 Yes 1 No Or calculated fields in UDM but all it awkward. I have about 50 bit attributes in all my dimensions. It would be too expensive to devote so much attension to every bit attributes. If you have a table as described, with a bit column (ID in your example) and a character column with the value you want displayed (Caption in your example), then you can create the attribute in your dimension so that ...Show All

• Visual Basic Multithreading cancellation Methode

  Hi All, Lately I explore about multi threading,because there is a urgent need to implement this feature.I came up with a case of multi threading cancellation. There is two kind of multi threading we have. 1. threading in the program itself. ex.

• SQL Server How to script Role Memebers

  Is there any way to script Databse Role(s) and Role Memeber(s) using SQL-SMO The workaround i am using here is, set the server connection execution mode to CaptureSQL and and use AddMemeber method while looping through Server.Database.Roles.EnumMemebers. This creates a string collection of sp_addrolemembers. (let me know if someone wants to have a look at this code) I couldn't even figureout how to do this using SQL Server Management Studion. When i script the entire database using SQL Server Mangement Studio, i dont see sp_addrolemember statements. Am I missing something Try something like this: Dim scrDBScript As Scripter Dim objSMOObjects(100) As SqlSmoObject Dim intObjCount As Integer intObjCount = ...Show All

• Visual C# Question about objects

  I am a novice c# programmer and have a rudamentary question. I have a class to handle permissions, so to check permission you have to open an object.

• Visual Studio Progammatically reload document from disk

  Hi Is there a way to reload a file from disk I'm looking for something similar to what the IDE does when it detects that a file has changed on disk and asks you if you want to reload it. Currently I'm looking for a way to do this from a macro. We haven't tried to do this as a proper add-in yet. Thanks Riko Hi Riko, The IVsPersistDocData(2) interface has a ReloadDocData method, that is typically used for this purpose. From the perspective on an addin, you'd have to get figure out how to get at this interface on the specific document you were interested in. You could enumerate through the IVsRunningDocumentTable documents, and use IVsRunningDocumentTable to retrieve the DocData object (basically the I ...Show All

  Hi all,   In the report I am working on, I have a "textbox39" in a table which has groups.

• Game Technologies: DirectX, XNA, XACT, etc. Game loop and update

  I find that the update mechanism of XNA is not completely right usually the order in the update makes sense because it's expected to be like this: UpdateInput (it can be from gamepad, netowrk ...) UpdateAI UpdatePhysic (or simulation) Using the GameServices collection it ca be reached if: GameServices.GetService<>() return a collection of services of type T and not just only one in this way you can write something like: inputservice[] inputs = GameServices.GetServices<inputservice>(); Foreach (inputservice is in inputs) { inputs.Update();} AiService[] ai = GameServices<AiService>() foreach( AiService ais in ai) { ais.Update(); } Otherwise now you can support extremly simple g ...Show All
