• Visual Basic Encryption - Storing Private keys

  Hi, I'm building an application to handle licensing some software i'm writing. I'm using the RijndaelManaged cryptography objects to encrypt an decrypt the license codes and database login info etc. At present i have the Key and Initialisation vector values stored as byte arrays private to my cryptography class. The code works fine. The problem is that when i use a decompiler on my dll the Key value byte array is fully visible, along with my Encryption and Decryption methods, thus rendering the security useless. My question is how do people actually store the Key value so that no one has access to it. I can't find any mention of how people actually do this, only how to use crytography once you have the key. I'm almost tempted to g ...Show All

• Visual Studio 2008 (Pre-release) How to get the Datacontract Serializer to ignore whitespace

  Is there a way to tell the Datacontract serializer to ignore whitespace in incoming messages I am getting values like "\n1234\n" instead of "1234" when receiving messages from a non-WCF service. If it is not possible with the Datacontract serializer, is it possible when using the XmlSerializer I know how to do it using the WhitespaceHandling property of an XML text reader, but I am trying to use the higher level features of WCF. Thanks, Kevin I discovered later that the issue was something like this coming from the device: <blah>\r\n 1234\r\n </blah> So, nothing wrong with the serializer, it was just delivering what was inside the element. Sorry, I forgot this question was still o ...Show All

• Visual Studio 2008 (Pre-release) Marker at each Point of a polyline?

  Hi, i have a polyline element with me, is it possible to have a "small vertical Line" or a small circle at each point of a polyline. More, is it possible to prgram which point should have this "Marker" and which sould not Thanks and Regards, brij There's no automatic way to do this, but it's actually pretty straightforward to write code to do. Basically, you need to draw two Polyline Elements at the same location with the same points. One, the "line" you simply stroke as normal. The second, you stroke with a thicker pen and a dash array constructed based on the Points such that there is one 0-length dash at each joint and you turn on round dash caps. Here's ...Show All

• Visual Studio Express Editions Image Transitions / Fades

  Hi Everyone, I am pretty new to VB, and have spent hours looking for a solution before posting here. What I want to do is create a screensaver that has transitions between image changes, rather than having one image disappear then the next image appear. I am absolutely certain this was possible with VB6 (see http://www.vbkeys.com/ctl18.aspx ), but I cannot find any support for VB 2005 Express. Does anyone have any ideas Is it even possible to do this with the new VB Cheers, Pat. one way would be to create a form which has the image control. Then on a timer tick event, fade the form via the opacity value. Then stop the timer. Once done, then load the next image, start the timer ...Show All

• Visual Studio 2008 (Pre-release) Multiple encodings on one EndPoint

  Is it posible to make single server EndPoint use multiple MessageEncodingBindingElements with the same transport If yes, than how can I do it Or it's better to use new EndPoint for each diferent MessageEncoder If I understood your problem I think that you should create MessageContracts instead of DataContracts and add MessageHeader inside Message that will represent compression algorithm. You could set comppression alg in write message method by accessing the messageHeader. On the server side inside Read method you could take first byte and just check is it starting xml character '<' which is byte 60 public override Message ReadMessage( ArraySegment < byte > buffer, BufferManager b ...Show All
