Hi Experts.

I had created a system driver, which is successfully installed in x86 system. But when i try to install in x64 it gives error, Unsigned Driver Installation Unsupported

Is there any logical work around so that unsigned driver can be installed in x64 system.

I am a individual developer, so i am unable to get code signing certificate.

please guide..

Regards,
Vishal

You can test sign a driver during development.
You can use some tools that come along with the WDK to do this.

Basically you first create a test certificate using MakeCert.exe.
You then install the certificate using CertMgr.exe.
Then sign the driver binaries using SignTool.exe.

The above method is use to sign the driver binaries.
You can also use Inf2Cat.exe to create a CAT file if your driver has an INF based package.

Another important step is that you must first put the system into Test Mode to install test signed drivers.
This applies to both steps mentioned above.

You can do this by executing the command bcdedit -set testsigning on from an elevated command prompt.

Thanx, can this method be used in the production environment..

Definitely not.
Because the test certificate is not strong enough and customers will not appreciate going into test mode.

sorry for late reply. Thanx for your valuable suggestion. I am considering Code Signing Certificate for Individual developer, I had talked to few providers, but they replied that only a business entity can get this certificate.

I found a couple of organizations that issue individual certificates -
http://www.globalsign.com/code-signing/[^]
http://forums.comodo.com/code_signing_certificate/code_signing_certificate_for_individuals-t34101.0.html[^]
You could also check with GoDaddy.
I believe they also issue individual certificates - http://www.godaddy.com/ssl/code-signing-certificate.aspx?ci=13314[^]

Hi Experts,

Is there any way I can get all logical drives information with follwing attribtes:

1. Active Partition
2. Start Sector number
3. End Sector Number

I never used these so i don't know much either, i just thought it might give you some pointers in the right direction. Anyways, could this[^] be what you are looking for?

Class is there to get sector number but its very confusing to get that.
Can you help to get the start sector of logical drive?

As said, i never used these so this is "new land" to me too, but the example on the site seems to be usefull, try to check that out, particularry, try to change this line:

hres = pclsObj2->Get( _bstr_t(L"DeviceID"), 0, &vtProp2, 0, 0 );

into something like this:

hres = pclsObj2->Get( _bstr_t(L"StartingAddress"), 0, &vtProp2, 0, 0 );

and this:

printf("%ls : %ls\n", vtProp.bstrVal, vtProp2.bstrVal);

to this:

printf("%ls : %i64\n", vtProp.bstrVal, vtProp2.ullVal);

or somesuch. Good luck.

Thanks for your help but could not get the address...I will try google to find something like you suggested.

Again Thanks.

In addition to my previous suggestion, take a look at the DeviceIoControl()[^] function and the FSCTL_GET_NTFS_VOLUME_DATA[^] control request.

I'm ready to start my SQL Server part of my program, but can't decide which version to use.

There is the native SQL Server sqlncli.h which I think uses SQLOLEDB. Sounds like the way to go, but some caveats exist. If the customer does not have the client installed, I have to download the client and install it for them.

I was looking for something more portable.

There is a sqloledb.h that comes up when I add the include, seems builtin, comes from microsoft sdk's in program files.

I don't want to start writing code, and have to start again.

What do you think?

This isn't really a coding question (has nothing to do with C/C++/MFC), it's more of a design or tools question, so another forum may be more appropriate.

With that said, I would compare databases available and pick one that has all the features your customer needs, don't worry as much about installation, worry about meeting the requirements (installation can be dealt with documentation). For example, some databases are going to be more appropriate for certain applications (i.e. maximum database size, type of data stored, types of queries, platforms supported, interfaces, security), so I would start by compiling a list of requirements, then do a comparison of databases available and pick whatever suits the overall application best.

I apologize for not phrasing the question right.

I already have an established database using Microsoft SQL Server 2008 Express Edition RTM 10.500.1601. that was written for a asp.net application.

Now I want to connect to the same database server using c++.

Oh, I see.. sorry... I'd choose something that doesn't require installation of another component. Supporting interactions with yet another "middle-ware" when you don't have to can become a pain.

Cool Thanks,

It's hard too find stuff on that, I've been looking for awhile. I'll going to try SQLOLEDB first and see how that works. I just needed a reference to get started.
