• .NET Development Protecting against characters that interfere with insert/update stmts

  I have an app in vb.2005/sql2005 that stores snippets of code, free form text, parts of web pages, anything. That's the problem. Some of the text that is dropped in as input to the table.column (nvarchar(max)), causes havoc with the insert or update stmts. error: "incorrect syntax near" usually followed by some random letter that when I track it down has some quotes around it. Particularly web source or lone sql stmts, (developers use this to store pieces of code they like). How can I encapsulate the input text in such a way as to not interfere with the finalized insert/update sql stmts A well managed text entry has no issues. Insert stmt : strSQL = "INSERT into Entries (myText, myDate, mySeq, keyWords, catalog, Path, p ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. RTS Camera

  Hi, I've went through any XNA game component, tutorial or forum thread out there and still can't find an example for what I need. Maybe someone could enlighten me or point me in the right direction! Trying to create a basic RTS style camera. The thing is when doing composite rotations no matter which axis I feed to the Rotate() method, eventually "yaw" and "pitch" rotations composite into a "roll".

• Internet Explorer Development Javascript focus() doesn't function well in IE7 with Tab feature using

  My problem is that: I can't use focus() to focus the tabs I have opened Example: On Opener Window, var tab = window.open(" www.microsoft.com ", "Child_Tab", "<LIST_OF_FEATURES>"); then call tab.focus() can't focus the opend tab "Child_Tab" Guessed Reason: May be IE 7 assume that all tabs in the same browser is in the same window.

• Windows Forms Is visual studio bootstrapper and clickonce bootstrapper the same thing?

  Is visual studio bootstrapper and clickonce bootstrapper the same thing Well, let me qualify that... There is a Visual Studio Bootstrapper associated with the Express SKUs of VS that is unrelated to ClickOnce bootstrapping. But you will also see in many places the Bootstrapper for ClickOnce referred to as the Visual Studio 2005 Bootstrapper. The official name for the ClickOnce related Bootstrapper is the Generic Bootstrapper, but that is not very descriptive either... ...Show All
