Internet Explorer Development keep System.Security.SecurityException from coming up
When I use this HTML : <a href="http://members.bex.net/commonmcd/downloads/PainterTest.exe"> <h3>Click here to download Drawing Program.</h3></a> users get this pop-up message : An exception 'System.Security.SecurityException' has occurred in IEExec.exe. What I want is for users to be able to download PainterTest.exe without changing the default settings in IE. They should get a pop-up box with a security warning asking them if they want to download PainterTest.exe. Not a cryptic security exception. The workaround is to right-click and click on "Save Target As..". It would be nice if they didn't have to do this, since a lot of users don't know how to do that. Thi ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Help me on How to fire a sprite to a mouse position from another Sprite
Hi again, this time i need some major help. I'm creating a shooter arcade, and the biggest problem i ran into so far was getting the sprite to fire towards my mouse positioned reticule. Could I please get some information on how to tell the game code that i want the sprite to move towards the mouse x,y from it's fixed positions. Thx for your help. One way to make one object "follow" another. 1) Create a new 'direction' vector as the difference between the two object's positions (object1 - object2) 2) Normalize the resulting 'direction' vector. This will create a 'unit' vector with no magnitude. 3) Negate the direction vector. This will set the direction of object1 to face towards ...Show All
Visual Studio Express Editions RichTextBox, Mouse Cursor issues.
Dear all, I have two questions and need to get some hints from u. :0) 1. Editor with the syntax functionality. In my ongoing editor, when the user types the word, e.g. "ABC", the word "ABC" will appear in the RichTextBox with the changed color red. Afterwards, when the furhter action is taking on, e.g. user gives the input directly in the RichTextBox or types the other word, the color will be back to default one, black. I made some basic implementations. E.g. add one richTextBox TextChanged event, and change it color afterwards. However, all the text in richTextBox will be changed, not as I wish. E.g. some specific ones will be changed, whilst the rest will be in the default color. 2. Mouse cursor. I designed one key w ...Show All

Visual Basic Setting properties differently in child Class.
How can i Set() properties differently in my base class. Cos i want to validate the values parsed in differently. I felt that overriding the Get() is not very good, its copy and paste. any better way to do this SJWhiteley wrote: Additionally, you don't need to copy the code in your sub new() functions if it's the same functionality. Just call the appropriate base function MyBase.New(...) (didn't we already do this in another thread ) Ya, i remembered, but didn't quite understand, so just to clarify, if in MyBaseClass, i have the Sub New() with code already, i just need to put Sub New() with no code in MyChildClass sorry i just a bit confused. ...Show All
Visual Studio 2008 (Pre-release) AssertNotDisposed Blows Chunks
ADO Orcas Team: It really sucks that you added invocations of AssertNotDisposed in ObjectContext. I don't remember anything implicit in the Dispose pattern that suggests that access to members of disposed objects should be restricted. Are you re-interpreting the idiomatic expectations of the semantics of the Dispose pattern by putting in arbitrary restrictions to state access on disposed instances of ObjectContext I can understand that you might wanna do something special for objects on the finalization queue, but the current implementation seems like a bit of overkill. It looks like more safety measures for clumsy people. It would be much nicer if you would simply let the chips fall where they may in regards to accessing state on a di ...Show All
Visual C++ missing msvcr80.dll
Hi, I made a small program (consoll) because I'm learning C++. I use Visual C++ Express Eition 2005. When all is done and I want to compile I get the warning that msvcr80. dll is missing and I can't run the program. Anyone know how to solve this issue. The file is on my HD, and I also repaired V_C++ through the net. But still the same problem. There are two other possibilities: 1) Are you using ZoneAlarm on your machine I've heard it has been known to interfere with files in the WinSxS. Uninstalling may solve the problem. 2) Are you compiling on a FAT32 drive (as opposed to NTFS formatted drive ) If so then try the FAT32 work-around (search the forum for other messages that will give further instructions ...Show All
.NET Development Force XML escape characters
I have to generate XML for some outside people. They want all escapable characters escaped. I am using Xml Serialisation because it is returned by a web service. .NET will only escape &<>, but not " or '. How can I force the escaping of all escapable characters Thanks guys for your help and your intentions. However, neither of your answers have solved my problem. I am using XmlSerializer to serialize an object into Xml. The people who will be consuming this Xml insist that all five of the characters specifically mentioned in the Xml specification are escaped. These characters are: & = & < = < > = > " = " ' = ' ...Show All
Visual Studio 2008 (Pre-release) endpoint certificate encodedValue
Hi How exactly do you create the value for the endpoint identity certificate in the config of the client side : < identity > < certificate encodedValue = " " This is generated for you by svcutil.exe when you generate a proxy/config for a service that provides service credentials for service authentication. The client must encrypt values using the service public key. This encoded value is that public key value base64 encoded. You could access that by exporting the public key from the certificate store, and opening the file in notepad, then running a base64 encoding on it...but svcutil.exe does this for you. If you didn't provide an encoded value, the service security set ...Show All
SQL Server New to IS -- please help me!!
Hi i am new to IS and I have been trying to use conditional split but cannot get the syntax to work. Can someone please tell me where i can find a syntax guide or samples especially on how to make the datetime funnction and maths function work. And, am I correct that the syntax is not as simple as they look in the conditional split transformation editor thanks!!! thank you darren. ok basically i am looking for the logic of the syntax. For example when i typed SUBSTRING(firstname,1,1) == "A" into the conditional split editor column, the parser can recognize this because the syntax itself is correct. Now, what is the syntax logic behind date / time and math functions Do ...Show All
