• Visual Studio 2008 (Pre-release) ReceiveTimeout: What is the price?

  I've been playing with the value of ReceiveTimeout in order to eliminate MessageSecurityException that we are getting after 10 minutes of inactivity. Increasing the value seems to work, and I tested 10 minutes, 1 hour, and even "Infinite". Now, I was thinking about how scalable increasing the ReceiveTimeout is. What runtime resources does the server dedicate in order to maintain higher timeout values What would the ramifications be for, say, 1000 users that may be "connected" to the server A related question: are there hard WCF timeouts that supersede config settings I've heard somewhere that there is 24 hours timeout that is imposed by the WCF (but this can be completely wrong). Thank you. ...Show All

• Visual Basic filling a bitvector32 in a loop

  Dear all, I can fill a bitvector32 like this: Dim InBytes As Int32 dim i for i = 1 to 1000000 InBytes = i 'for example Dim InBitVector As New System.Collections.Specialized.BitVector32(InBytes) next i and then I can read out the individual bits (need this for a graphics conversion). Problem: this gets VERY slow, and I trailed that to the Dim InBitVector statement. Is there ANY way to assign an Int32 number to the InBitVector WITHOUT using the dim statement Thanks, Kees Hmm, odd. It shouldn't make any difference and it didn't when I tried it. There is however a huge difference between running the release mode or debugging with the IDE, I ...Show All

• Visual C# Having only one process running

  Basically, this is what I am trying to do: When a user runs the app, the first process is created, however, when a user then attempts to run the app again, rather then a new process be created, I want the the new process to recognoize that there is a process already running, and to tell the existing process to spawn a new window (form) and then die. At this point the existing process spawns a new window (form) and life goes on. I believe the basics of spawning the windows (forms) are through the use of Threads, and I have the basics of the forms being created correctly, and the and keeping the process alive through the life of the different threads, but, I can't figure out what I need to do to get the 2nd process to not run and instead use ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. alpha channel in xna

  I was wondering, how can i set the alpha channel in xna game studio i have a 2d image and i want to set the transparancy of the image manually on run-time and from what i read in the documentation, the alpha channel mentioned there are only for the bmp or png files with transparant background while i need to set the transparancy to the whole image. Any help would be welcomed.. Use the Color parameter of the Draw method of the SpriteBatch class to set the transparency.

• Visual Basic Sub Main in Mainform.vb never getting called.

  If I create a Sub Main in my app, the app never calls it. No breakpoint hit, no Messagbox shown. Thanks for any ideas. -greg MainForm.vb Friend Class MainForm Inherits System.Windows.Forms.Form Sub Main (ByVal cmdArgs() As String) MessageBox.Show("main") End Sub End Class MainForm.Designer.vb Partial Class MainForm Inherits System.Windows.Forms.Form You DMan.  That makes perfect sense. The reason why why want to use sub main it is to put control instantiation code prior to the forms initializecomponent.

• Windows Search Technologies WDS 3.0 Final: Exception occured while trying to run "shell32.dll,Control_RunDLL "srchadmin.dll""

  Hi again, I got this, too! I've seen a few threads here relating to this issue, although the thread starters often used the Beta versions. I get this problem when I click on the File Types tab in the "Advanced Options" I tried: REGSVR32 SHELL32.DLL and sfc /scannow No dice. I uninstalled the program, and reinstalled it. Same problem. And even worse, all my SIX taskbars disappeared! Argh, I have four rows of icons on my taskbar, and now I have to set up everything again. This will set me back an hour.

• Visual Studio Team System Trouble With Web Deployment Project and Team Build

  I'm trying to deploy a simple web site using Team Build and the Web Deployment Project. The web site builds fine on its own. On the property pages for the Web Deployment Project, under the Deployment section checked the box for "Create an IIS virtual directory for the output folder" and entered a name for the virtual directory. Every build from then on failed with the error stating "Error Virtual Director 'x' already set to path c:\documents and settings\..._deploy\Debug".

• Visual C++ Create a dialog box in a COM dll without CWinApp

  Hello! I try to build a COM dll addin which is designed to work together with an external application.. an exe. The dll is not using CWinApp. In the same time, I can’t add DIRECTLY a resoursce - a dialog window in this dll. From the addin point of view I just can obtain almost everything i need from the exe: the application, view, or document objects of executable. It is still possible to insert a dialog box in this addin, which need to communicate with the exe, and put some buttons, and other stuff in it For exemple i need a simple dialog box created inside the dll which has one button, and allow me to selected some screen entities from exe working area.

• Visual Studio Tools for Office Debugging VSTO2007 for Outlook addins...

  Hello all, I have an existing addin that runs/installs fine in Outlook2003 with VSTO2005. I have migrated it over to Outlook2007 with VSTO2007 and it runs in the debugger fine. However when I create the setup project and install the addin, it will not get loaded when Outlook is launched. Is there a way to debug or get more information about why the addin is not getting loaded I tried to set the VSTO_SUPPRESSDISPLAYALERTS=0 and that does not seem to show the more information box like in Outlook2003. Thanks in advance, ~Joe There are actually several questions here. First, add-ins registered in HKLM have in the past sometimes posed a security concern - as these are not visible in the UI so the ...Show All

• Software Development for Windows Vista Is there any wat to get the GUID for the underlying DirectSound device out of a DirectShow DirectSound audio renderer?

  I have an application that needs to be able to play sounds of all different types, and that needs to support different libraries. It's sound configuration uses DirectSoundEnumerate() to run through the list of DirectSound devices, and uses the GUID of the DirectSound device to uniquely identify it. (This GUID gets saved into configuration files and persists between app restarts) Some of the audio that my application plays is run through DirectShow, however, and I want to guarantee that the DirectShow audio comes out of the same audio device as the rest of the system (which uses DirectSound directly). DirectShow offers a DirectSound Renderer filter for each DirectSound device in my system, but I haven't been able to find a reliable ...Show All

• Visual Studio Looking Up Values In Other Fields

  Good Morning, Just can not get my head around the following and am sure there is a simple way around this. In Crystal reports, I just want to create a lookup-type formula which will display a certain value from the same table. Example: Ref Value IF R ---- ------- ------ 10 ￡100 ￡500 11 ￡200 ￡0 12 ￡300 ￡600 R10 ￡500 ￡0 R12 ￡600 ￡0 So simply, at each line, the 'IF R' formula would in turn look at the ref fields and display the Value if there is an existance of an R** ref. Would I have to create a subreport to achive this Thank you in advance for your response. Paul Carruthers If the "R" is always in front, you could use a formula if left({usp_rptReport;1.Ref},1)="r" th ...Show All
