• Visual C# How do you change the value of an already created cookie?

  Below is the code I'm currently using on my login page to save the username and password. I'm going to later encrypt it but for now I'm simply setting it.  HttpCookie UNcookie = new HttpCookie("TheUsername",txtUsername.Text); UNcookie.Expires = DateTime.Now.AddYears(1); HttpCookie PWcookie = new HttpCookie("ThePassword",txtpass.Value); PWcookie.Expires = DateTime.Now.AddYears(1); Response.SetCookie(UNcookie); Response.SetCookie(PWcookie); The code works great the first time I run it. If I go back to the page I am presented with the information that was saved.  If a new user logs in on the same machine and acct, the ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. pixel shader computation: precision problem?

  Hi, I do the following computation in a pixel shader:   const float texel = 1.0 / 128.0; result = floor(In.texcoord.w / 16.0) / 64.0 + texel   In.texcoord.w containes an integer value between 0 and 299, stored as a float, interpolated over the triangle, where each vertex stores the same value, so in practice there shouldn't be any interpolation happening.  When I output result as a color, I notice distortions over the triangle and a flickering when I move the mouse, for some values of In.texcoord.w. But actually the result should be constant for each of the triangles pixels because the computation use ...Show All

• Windows Forms ClickOnce fails only on first time launch

  Hi, I've successfully deployed an app. to my website using ClickOnce (VS2005 beta 2).

• SQL Server Could Not Bulk Copy

• .NET Development custom marshalling of System::Object* to VARIANT and back again in IJW assembly

  I have two native C++ functions: One takes a VARIANT as its argument and the other returns one. I'm compiling these functions using the Managed C++ compiler to create an IJW assembly, and I want to provide real managed functions that take and return System::Object* instead. They would just marshal the arguments and call the VARIANT version to do the real work. I know that this must be possible without too much magic involved because the P/Invoke automatic marshaller can do this, but I'm unfortunately not using P/Invoke here... Actually... I finally got it to compile, but I still don't know if it's ...Show All

• .NET Development SmtpClient.Send() problem results in "An established connection was aborted by the software in your host machine"

  Hi, I'm having problems with SmtpClient.Send() where I end with an "An established connection was aborted by the software in your host machine" type error. My infrastructure people tell me that I should have access to the Smtp server so things should just work. I've been googling and searching forums but have yet to see a complete answer to what this error is trying to tell me. Oh and I've tried this in both a Web and a WinForm app on .Net framework 2.0 running on a clean install of XP Pro. Any opinions Thanks Scott.

• SQL Server Upgrade Advisor does not detect SQL Server on IA64 stand alone or cluster

  When using the upgrade advisor remotely from a Windows 2003 server sp1 with SQL 2005 installed on it, the advisor only recognizes DTS on our Itanium stand alone and clustered SQL 2000 servers. I tried running the upgrade advisor locally on the stand alone and it does not even see DTS locally, (it detects no SQL Server components). When I select the components, the next window prompts me for an instance name even though both the stand alone and the cluster are default instances. Has anyone else experineced this running the upgrade advisor against IA64 stand alones or clusters Hello, The detection logic ...Show All

• Smart Device Development TextOut() in Smart Device Application (VS2005)

  It doesn't working... Help please, I'm a beginner. Hi Riven, The TextOut function is not implemented in Windows CE (the base OS on which Pocket PCs are built), there are two possible replacements: DrawText and ExtTextOut. Windows CE doesn't have the full API set that you are used to on the desktop, which can be inconvenient at times, but allows CE to run on very hardware constrained devices. I found the information on TextOut in an article by Paul Yao: http://www.microsoft.com/msj/0598/wince.aspx . Windows CE 5.0 (Windows Mobile v5.0 for Pocket PC is based on this version of the OS, Pocket PC 2003 is based o ...Show All
