Following my presentation to the Perth .NET Community of Practice BUY Singulair ONLINE NO PRESCRIPTION, last night I thought that I would start documenting some of the features that I demonstrated. The first of these is handling user access control (UAC) under Vista. This is particularly important if you want your application to request administrative privileges on startup (rather than getting into the application only for it to blow up when it tries to do something that requires admin rights).
Under Visual Studio 2005 dealing with UAC involved a number of steps and a bit of a hack if you are signing your application. Before we get onto how Visual Studio 2008 improves this process I'll go through how to enable your application using VS2005:
Visual Studio 2005
Step 1 - Add a Manifest File
Essentially this step involves creating a text file that is named <application>.exe.manifest and adding it to your project, canada, mexico, india. Singulair over the counter, In fact the file doesn't even need to be part of the project in VS2005 so long as it is in a known location (see Step 2).
The contents of the manifest file should look similar to the following. Basically you are adding information to the assembly that indicates what the required security level for your application is. In this case it is set to "requireAdministator" which will force Vista to prompt the user with the UAC dialog in order for the application to run with Administrative privileges, Singulair pharmacy.

Step 2 - Including the Manifest file in the Build
VS2005 doesn't natively understand how to integrate a manifest file into the build process. As such you have to add this step in as a post-build event using an SDK utility, mt.exe. This can be done using the following macro (just insert this into the post-build events dialog accessible via the project properties dialog):
"$(FrameworkSDKDir).\Bin\mt.exe" -nologo -manifest "$(ProjectDir)$(TargetFileName).manifest" -outputresource:"$(TargetPath);#1"
At this point you should be able to build and run your application. You will note that even if VS2005 is not running as Administrator you will not see any UAC prompts (which you would expect if you were to run an application that requires administrative privileges). This is because this post-build macro only adds the manifest to <application>.exe whereas the debugger (by default) attaches to <application>.vshost.exe. If you disable the VS hosting process (see Project Properties->Debug->"Enable the Visual Studio hosting process") you will get a nasty exception:
"Error while trying to run project: Unable to start program '.....\VistaWithVS2005.exe', rx free Singulair. the requested operation requires elevation."
Step 3 - Resign your application (required if you sign your application)
Unfortunately running mt.exe as a post-build macro modifies the assembly which of course means that if the assembly was signed, it will fail validation when you attempt to run the application. In fact you will get a build warning:
mt.exe : general warning 810100b3: c:\....\VistaWithVS2005.exe is a strong-name signed assembly and embedding a manifest invalidates the signature. You will need to re-sign this file to make it a valid assembly.
To get around this we need to include a second post-build macro that will re-sign our application:
"$(FrameworkSDKDir).\Bin\sn.exe" -q -Ra "$(TargetPath)" "$(ProjectDir).\mykey.snk"
Unfortunately this alone doesn't fix the build warning as the application is still signed during the initial build. To tidy up the build output you just need to tell VS2005 to delay the signing of the application:
With these changes your application should now be ready to run against Vista and because the manifest is simply ignored by earlier versions of Windows you shouldn't see any adverse affects, BUY Singulair ONLINE NO PRESCRIPTION. Austin, Texas, Memphis, Tennessee,
Visual Studio 2008
The process for adding the manifest file to VS2008 is much simpler than for VS2005 as the build process understands how to incorporate an application manifest and how to attach to a process that requires administrative privileges.

If we now attempt to build and run this application we will see that VS2008 detects that we are about to run and attach to an application requiring administrative privileges. The following prompt is raised allowing us to restart VS2008 in administrator mode.
If you agree to the restart VS2008 will not only restart with administrative privileges (it will give you a second Vista UAC prompt that you will have to approve), buy Singulair from canada, Singulair over the counter, it will also reopen your solution including all files you had open.
