Is there any posibility to load SOS extension in visual studio 2010/2012 (.Net framework 4) for x64 process?
If you install VS2012 and the WDK, you can attach to a 64 bit process via the User Mode Debugger transport protocol (option under the attach to process dialog). If you do that, you can load SOS from the new Debugger Immediate Window. This works for both 32 and 64 bit processes.
It's not possible. For debugging 64 bit applications with SOS, you have to use windbg.

I have a new VM on which I have installed Visual studio.
I created a new SSIS project, and am trying to use the oledb data source task to access an .accdb MS-Access file.
However I cannot see the Provider. So I installed the Access 32 bit runtime. Now I can see the provider. I am reading that since visual studio is a 32-bit tool, we have to install the Access 32bit runtime. Otherwise if we install the 64bit runtime, then we will not be able to see the provider in the list because visual studio is 32bit and only shows 32bit providers.
When I hit the debug button in visual studio SSIS project it can access the MS-Access file. I am now confused and want to ask - when the project is running, does it run in 32 or 64 bit mode? If the answer is 64bit mode, then how can it access the MS-access file using the 32bit provider? Does it mean that project running in 64 bit mode can utilize 32 bit mode runtime/provider?
Assuming no settings are changed, when debug button is pressed, then does the program execute is 32 or 64 bit mode? Does the OS bitness have any impact on this?
You are quite right and quite close here.
Since Visual Studio is x32 bits?
Well, if your project is set to x86 (x32 bits) or set to ANY CPU?
Then hitting F5 to run + debug (or ctrl-F5 to run the .exe without debug), then you will get (have) a x32 bit running program. Some caution here. If you use ANY cpu? then again FROM VS f5 to run - you get a x32 bit process.
But, if you go to the windows commnd line?
Well, if you launch teh windows x64 bit command line (default on most computers), then if the project is ANY cpu? Then your app run will be x64 bits. (and ANY un-manged code such as Access, or any other windows code used for COM autoamtion? it will break.
If you launch the windows x32 bit command line (with any CPU) then you get a x32 bit version running.
So, from VS - F5 - always x32 bits.
From windows command line - depends.
So, what above suggests? Well, if your intention is to have + use x32 bits process? Then FORCE/SET the project to your intentions. That way, no "by chance" will fool you, and your application will ALWAYS run as to the project settings.
So, in such cases, I do avoid ANY CPU.
Now, what happens if you force the project to x64 bits? eg this:
Well, if you pick x64 bits? (and not any cpu, and not x86).
Then hitting f5 (or ctrl-F5), it WILL run the application as a x64 bits in-process. I am not sure quite how VS works, but they have some kind of "bridge" that marshals the x64 bit debugger to talk to VS x32 bits.
So, if you force the project to x64, then it will always run as x64 bit - including from VS.
So, this means:
if you set project to x64 bits - use a connection builder in settings?
You can use the connection builder but since (we assume) that you using
access x64 bits? Then the test connection button in VS will NEVER work.
But, if you run the code as x64, and have access x64, then it will work. So ONLY the test connection button fails - and that's due to VS being x32.
If you have even the wrong version of Access (say x32 bits), and your project is set to x64? Then the connection builders will work and EVEN the test connection will work (because test connection is ALWAYS x32 bits from VS). This has the effect of you building a connection, hitting test connection - it says good!!! But when you run the project (f5, ctrl-f5), the project runs as x64, and it will fail (this example assumes x32 bits).
Now this is building an writing code from VS. I don't' know of a SSIS package built with Visual Studio works different. But we do NOT want to confuse Visual Studio (VS) with that of say sql studio or other systems - they don't have the project "cpu" or "bit" setting options like you do for a VS project.
So, I quite much suggest if your intention is x32 bit operations, then ALWAYS force the VS project to x32 bits, and thus come time to launch that .exe from windows, then it will never run with a wrong or un-expected bit size.
I not tested a SISIS integration project, but if building this from VS? Then once again, force/set the project bit size.
In effect to remove the "chance" of the wrong bit size? Then force the project to the given bit size you as the developer were intending to use here - that way this is not left to chance.
There ARE times when you want to use ANY cpu. A really good example is when you build say class library code to share amoung projects. In that case, ANY cpu is a good choice, since then EVEN projects forced to x32 or x64 can referances those external assemblies and library code.
However, if you force those external assemblies to a given bit size, then only projects running that that correct bit size can consume such libraries.
.net code (managed) is differnt then un-managed code. .net code has the ability to run "either" x32 or x64 if you choose ANY cpu. But un-managed code (external non .net code such as Access) can't change on the fly like .net code can. And I use the term "on the fly lose here". Since ONCE a .net program starts running x32 or x64? It remains that bit size until terminated.
So, ANY CPU is fine for external class library code you write and thus want to include in any project. But the main project .exe program has to use SOME external non .net (non managed) code? Then you would do very well to force the project bit size settings.
And to answer you last question?
If the provider is a .net one, such as sql provider or whatever? Then it is managed code - cpu settings don't matter. it is ONLY when you start using external code systems that are NOT managed and NOT .net code. MS-Access is one such common example. So would be any windows c++ or even a lot of commerial programs.
For example. Sage/Simply accoutning, and Quickbooks accounting? They offer .net SDK's to interface to those accoutning packages. But they only have x32 bit verisons of those desktop programs - and they are not .net prorgrams. So once agian, you do well to force the project to x32 bits.
So, no x64 bit process can consume a x32 bit process. nor can you consume external librares that don't match.
However, if that library code and system is .net (managed code), and was compiled and created with any CPU, then you don't have any restrictions in regards to using ANY cpu, or even consuming those libraires when you force the .net project cpu settings.
So this whole system ONLY breaks down when you introduce or start using external code libraires.
For example, if you use .net ghostscript library? They have two versions - x32 and x64. And thus just like MS-Access you have to match up the bit size of those external libraries.
This actually is a REALLY nasty problem say for Adobe PDF. Their pdf viewers are x32 only. In fact it was only what - last month they started offering x64 bit versions of their PDF adobe reader. And they no doubt started doing this since office is now moving towards being x64 bits and not a x32 bit system/program.
I am trying to run my visual studio (2010) C++ project on an old Windows XP machine that is running VS2010. However, when I run it, I get the error listed in the title of this question. Why is this, and how can I fix it?
Same error was throwing for me when I had Silverlight debugger enabled. To resolve this issue
Open project properties
Under web tab look for Debuggers
Remove the tick mark on "Silverlight"
In general, a debugger should be the same bitness as the debuggee (or at least it must be able to understand the architecture of the target). In any common siutation, an x86-based debugger will not be able to debug an x64 application.
The Visual Studio documentation says:
To debug a 64-bit application that is running on a remote computer,
you need to install the 64-bit remote debugger on the remote computer.
The 64-bit remote debugger is available on the last disc of your
Visual Studio installation set.
my Windows 7 is 64 bit. My Visual Studio project is target to x86. I have installed this:
http://www.microsoft.com/downloads/en/details.aspx?familyid=C06B8369-60DD-4B64-A44B-84B371EDE16D&displaylang=en#Requirements (the x32 version).
I get this error message: The 'Microsoft.ACE.OLEDB.14.0' provider is not registered on the local machine.
What do I wrong?
When you build the project you need to specify that you're specifically targeting x86 CPUs, not Any CPU.
I don't have VS 2010 installed here, so can't tell you exactly what to do, but either . . .
From the drop down that says "Any CPU" select x86.
Or on your project properties page (of the exe project) select "x86" for "Platform Target"
You need to take a look at 32-bit Microsoft ODBC Administrator to register the 32-bit driver. The one under Adminsitrative Tools is 64-bit only. Go to Windows\System32\, the search for odbcad32.exe. Click on System DSN, and register the 32-bit driver.
I'm using "Microsoft Access Database Engine 2010 Redistributable" in Win 7 64 bit without any issue. Try to install 64 bit version of "Access Database Engine".
I've got the following configuration
Win 7 64 bit
VS 2010 32 bit (there is no 64 bit)
Microsoft Access Database Engine 2010 Redistributable 64 bit

CpupSyscallStub is what I See for all threads, in Windbg I can switch to 32-bit mode and get the real threads.
How do I do this in VS2010?
I noticed that a 32-bit dump can also be created with the 32-bit task manager ("%systemroot%\syswow64\taskmgr.exe"). Close the existing 64-bit taskmgr first.
How did you take this process dump? via Task Manager (taskmgr)?
If so, it is a 64-bit dump of a 32-bit process and these cannot be debugged with Visual Studio 2010, and there is no way to switch the architecture.
Try retaking the dump using Visual Studio or WinDbg or ADPlus.
You can read more about types of dumps, etc. # MiniDumpWriteDump (http://msdn.microsoft.com/en-us/library/ms680360(VS.85).aspx)
Try using ProcDump. It captures 32-bit processes as 32-bit dumps by default.

I'm wondering if I can still develop 32-bit apps using a 64-bit machine (64-bit Windows Vista with Visual Studio 2008 SP1)? Because I am planning to buy a laptop with 64-bit Vista. Im asking just to make sure. Thanks!
64-bit Windows runs 32-bit Visual Studio just fine. Unless you specify you wish you use the x64 development tools, it will still compile 32-bit applications.
Straight from the page:
Visual Studio uses the 32-bit cross
compiler even on a Windows 64-bit
computer. You can, however, use devenv
commands to create a command line
environment to call 64-bit hosted
tools.

With Visual Studio you are able to target what platform. By default it will run on "Any CPU" (read 32 or 64 bit), but you can specify if you desire. Look under Project>Properties>Build and look for the "Platform Target" property.
Yes. 64-bit vista will run 32-bit executables, so if you have a 32-bit compiler, it will still work.
Within visual studio you can tell it what to compile to under the Configuration Manager - (Build Menu - Configuration manager) - this allows you to target 32 or 64 bit.
64bit of consumer hardwares is usually "amd64" architecture which can run both 32bit apps and 64bit ones natively. Windows Vista 64bit edition supports both 32bit and 64bit system libraries, so basically you can run both type of applications as well. (Note that IA-64 architecture does not allow this.)
Compiling a program in 64bit is not much related to the platform that the compiler runs. But, of course, to run and test the result binary requires the corresponding architecture.
As many mentioned above, VS2008 let you choose the target architecture, so there's no problem.
I've found that just the setup.exe created by Visual Studio 2012 Express won't work on XP, but if you go ahead load MS 4.0 .NET Framework from the Microsoft Website then the *.application will load and install without using the setup.exe at all.
