Native x86 Android runtime will enable Android apps on Windows

2011 May 26, 1:28This was on my todo list. I'll scratch it off knowing far more funded folks are doing this: "A startup called BlueStacks has developed an Android runtime environment for the Windows operating system. It will enable users to run Android applications alongside conventional Windows software on Microsoft's operating system." "One example would be a convertible netbook tablet that normally runs Windows but switches to an Android interface for greater touch-friendliness when the screen is flipped.
Such a product would offer the full power and multitasking capabilities of Windows but also benefit from having access to Android's broad touch-enabled software ecosystem."PermalinkCommentswindows programming android java technical

_opt Mnemonic

2011 May 24, 11:00

​I always have trouble remembering where the opt goes in SAL in the __deref_out case. The mnemonic is pretty simple: the _opt at the start of the SAL is for the pointer value at the start of the function. And the _opt at the end of the SAL is for the dereferenced pointer value at the end of the function.






SAL foo == nullptr allowed at function start? *foo == nullptr allowed at function end?
__deref_out void **foo No No
__deref_opt_out void **foo Yes No
__deref_out_opt void **foo No Yes
__deref_opt_out_opt void **foo Yes Yes

PowerShell Script Batch File Wrapper

2011 May 22, 7:20

I'm trying to learn and use PowerShell more, but plenty of other folks I know don't use PowerShell. To allow them to use my scripts I use the following cmd.exe batch file to make it easy to call PowerShell scripts. To use, just name the batch file name the same as the corresponding PowerShell script filename and put it in the same directory.

@echo off
if "%1"=="/?" goto help
if "%1"=="/h" goto help
if "%1"=="-?" goto help
if "%1"=="-h" goto help

%systemroot%\system32\windowspowershell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned -Command . %~dpn0.ps1 %*
goto end

:help
%systemroot%\system32\windowspowershell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned -Command help %~dpn0.ps1 -full
goto end

:end

Additionally for PowerShell scripts that modify the current working directory I use the following batch file:

@echo off
if "%1"=="/?" goto help
if "%1"=="/h" goto help
if "%1"=="-?" goto help
if "%1"=="-h" goto help

%systemroot%\system32\windowspowershell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned -Command . %~dpn0.ps1 %*;(pwd).Path 1> %temp%\%~n0.tmp 2> nul
set /p newdir=

Patterns for using the InitOnce functions - The Old New Thing - Site Home - MSDN Blogs

2011 Apr 8, 2:32"Since writing lock-free code is issuch a headache-inducer,you're probably best off making some other people suffer the headachesfor you. And those other people are the kernel folks, who have developedquite a few lock-free building blocks so you don't have to. For example, there's a collection of functions for manipulatinginterlocked lists.But today we're going to look at theone-time initialization functions."PermalinkCommentstechnical windows programming raymond-chen lock thread-safety

Capturing HTTPS with FiddlerCore

2011 Apr 6, 10:00

I used FiddlerCore in GeolocMock to edit HTTPS responses and ran into two stumbling blocks that I'll document here. The first is that I didn't check if the Fiddler root cert existed or was installed, which of course is necessary to edit HTTPS traffic. The following is my code where I check for the certs.

    if (!Fiddler.CertMaker.rootCertExists())
{
if (!Fiddler.CertMaker.createRootCert())
{
throw new Exception("Unable to create cert for FiddlerCore.");
}
}

if (!Fiddler.CertMaker.rootCertIsTrusted())
{
if (!Fiddler.CertMaker.trustRootCert())
{
throw new Exception("Unable to install FiddlerCore's cert.");
}
}

The second problem I had (which would have been solved had I read all the sample code first) was that my changes weren't being applied. In my app I only need the BeforeResponse but in order to modify the response I must also sign up for the BeforeRequest event and mark the bBufferResponse flag on the session before the response comes back. For example:

    Fiddler.FiddlerApplication.BeforeRequest += new SessionStateHandler(FiddlerApplication_BeforeRequest);
Fiddler.FiddlerApplication.BeforeResponse += new SessionStateHandler(FiddlerApplication_BeforeResponse);
...
private void FiddlerApplication_BeforeRequest(Session oSession)
{
if (IsInterestingSession(oSession))
{
oSession.bBufferResponse = true;
}
}
