• Software Development for Windows Vista Using smartcards in a service - SCardAccessStartedEvent

  Dear all, Migrating our core development platform to Windows Vista, one of our Windows services using smartcards is failing. We have debugged the problem and found that the event provided by the function ScardAccessStartedEvent does not receive notification. This event is supposed to signal when the SmartCard Resource Manager starts. As we have a WaitForSingleObject(event,INFINITE), the service hungs. Testing the same service as an ordinary executable ( registering with -regserver ) I can see it works properly. In XP it works properly both as an executable and service. I have read something about Service Hardening in Vista and I guess it may be caused by privilege reduction. So, I've created some code to enumerate the existing ...Show All

• Windows Forms How to handle errors?

  Hello, If some programming state is not okay (like finding that a SerialPort is not open prior to sending data) I would like to show some error message. I would like to handle all error messages-displaying in a central place by a single function. How do I achieve this (As a newby in C#, in Borland C++ I was used to use a global string for storing the error messgae which is displayed when all nested functions return false). But C# does not allow a global string( ), or what other mechanism is usually applied for this purpose All tips and hints are welcome. regards, Henk Okay thanks, but what should I use if a user-handling-error has occurred that is detec ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. World to screen conversion.

  Hi. Something weird when trying to covert world to screen coordinates. Vector3 res = Vector3.Transform(worldPoint, Camera.View * Projection); I get the result vector with values greater than 1. Aren't the values post projection supposed to be clamped Both the view and projection matrices are valid (and are used to display on screen). Cheers googling for that will totally turn you away from 3D drawing. if you have a 4D, or homogeneous, point, you simply need to divide the first 3 coordinates by the 4th coordinate. Then you get the usual 3 coordinates. You're only interested in the first 2 coords, but after dividing they're in the [-1, 1] region, so you need to divide by 2 and add +0.5 to get them in the [0, 1] region. A ...Show All

• Visual Studio Express Editions String Format

  Does anyone know how to re-arrange characters in a String For example: change Smith, John to John Smith and remove the comma. Also, can this be done for any name length and not just for John Smith Thanks! Lookup the split () and the Trim () methods for a string which returns an array of strings and trims characters respectively, for example: Dim fullName As String = "Freddy Fourfingers" Dim names() As String = fullName. Split (" "c) Debug.WriteLine( String .Format( "{1}, {0}" , names(0), names(1))) Or the other way: Dim fullName As String = "Fourfingers, Freddy" Dim names() As String = fullName.Split(" "c) Debug.WriteLine( String .Format( "{1} {0}" , names(0).Trim(","c), names(1).Trim(", ...Show All

• Software Development for Windows Vista When will calling Release() after calling CoUninitialize() not result in an AV?

  (can you redirect me if this is not the right forum for this question) Should this sequence cause an AV I made the fairly common mistake highlighted in yellow, and fixed it, but I was surprised that it resulted in an AV only if COM had not been initialized on Thread A. I would like to understand why or why not I should expect an AV in this case. Thread A calls CoInitializeEx Thread A creates Thread B Thread B calls CoInitializeEx Thread B creates and uses some COM objects Thread B calls CoUninitialize Thread B releases COM objects <--Bug Thread A calls CoUninitialize Here is an answer from my colleague, Axel: “If both A and B are in an MTA, the CoInitializeEx ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Animating Billboards Using A Single Texture

  I just finished a basic billboard class that is capable of reading in multiple textures and animating. However, I would like to read in a single texture file and be able to simply change texture coordinates to change the appearance of the billboard. Now, I could recreate my VertexBuffer each frame, but that would be a lot of wasted processing. Is there a way to dynamically alter the texture coordinates for VertexBuffer objects each frame Edit: As a bonus question, how do I enable the alpha channels in my textures Right now it shows up white. I am using the BasicEffect. Would I have to write my own effect just for that Seems rather silly but I will if I have to. Edit 2: As bonus question 2, how can I disable antialiasing of my textures I'm ...Show All

• Visual Studio Tools for Office Question re the CRM Integration Add-In Sample For Outlook 2003 (2)

  Earlier on I was questioning the UI/Data separation logic and John Durrant pointed me to the "CRM Integration Add-In Sample" - thankyou it is very useful. There are four custom items in this sample: Accounts, Activities, Opportunities, Contacts. As far as I can see, for each item stored inside an MSSQL database, an item is also created within the default Outlook store. I have deduced this because there is an 'OutlookID' column within each of the database tables. My question is this. What if I wanted to take the data/UI separation one step further for this model for an Outlook 2007 add-in What if I wanted to avoid the synchronisation issue between the Outlook and MSSQL data by saving only to the database. To achieve this I could ov ...Show All

• Visual Studio Team System Grouping Query Clauses

  Hi all, Maybe this is a really stupid question but I have been trying to create a work items query such as this one (Team Project = @Project) AND ((Priority=3 AND State=Proposed) OR (Priority=1 AND State=Active)) and I cannot work it out. I thought the "grouping" feature would help me but it doesn't work as I would expect it. The problem is with operators. How to put them outside the brackets The query in VSTS looks like this Team Project = @Project ((AND Priority=3 AND State=Proposed) (OR Priority=1 AND State=Active)) which does not return the expected results. What am I doing wrong It seems impossible that this cannot be done. -Clara. Clara, Though in the UI it ...Show All

• .NET Development About Cryptography.RSACryptoServiceProvider's behavior

  Hi, every one. I have searched/used Cryptography.RSACryptoServiceProvider for a while and found a interesting behavior: When you create a pair of keys(private+public, short for "private", obtained by ToXmlString(true); public only, short for "public", obtained by ToXmlString(false) ), then you can encrypt/decrypt data. I found that if I encrypt with public, then decrypt with private, no error pop up. But when I encrypt with private, decrypt with public, then error popup, said "bad key". I saw some articles said: if you encrypt data with one key, you have to decrypt with other key. and my test shows one direction result. Maybe what I thought is wrong Any one has similar experiences ...Show All
