Visual C++ :: How To Tell If Drive Is BitLocker Encrypted Without Admin Privilege

May 24, 2014

For my purpose all I need to know is drive's BitLocker encryption status by its DOS path. Something like this:

Code:
enum DriveEncryptionStatus{
Unprotected,
Protected,
Unknown
};
DriveEncryptionStatus = GetDriveBitlockerEncryptionStatus(L"C:");

I was able to find the Win32_EncryptableVolume class that unfortunately comes with this caveat:

To use the Win32_EncryptableVolume methods, the following conditions must be met:

You must have administrator privileges.

How to do this without running as an administrator?

C++ :: Reduction Of The Flash Footprint

Nov 26, 2014

I'm currently involved in an embedded (cortex M3) C++ project where we're about to run out of flash.

A quick check of the map file give that, in our case, the destructors consume about 10-15% of the available space. Since we're allocating all things that are needed at startup but never delete anything (both a requirement & also impossible due to the lack of a proper memory manager) the thought of getting rid of all destructors in the target build is appealing.

I know that this question is somewhat crazy/desperate but is there a safe way of telling gcc not to emit any code for destructors? If so, can that be made in such a way that a linker error catch for instance mistakes such as creating an object on stack?

C :: Retrieving Values That Are Stored To Compact Flash Card

Sep 19, 2013

My specific request is for retrieving values that are stored to a CompactFlash card. I am able to store values (we call them recipes) to the CompactFlash card as .csv file. I just haven't been able to figure out the code to retrieve this information back to the touchscreen.

Code:
// Create a new folder if it doesn't exist
CreateDirectory("/recipes");
//Create the file if it doesn't exist
CreateFile("/recipes/recipe.csv");
//open the file
hfile = OpenFile("/recipes/recipe.csv", 2);

[Code]....

Now with that said, I would like to retrieve these values from the .csv file.

C++ :: Flash Card Type Console Application - Declaring Array Of Hexadecimals

Dec 26, 2013

I'm making a flash card type console application using visual studios 2013. The flash cards contain character that I can display using unicode. So far I am looking at about 200 characters across 2 unicode blocks which I don't want to hard code into my arrays. I thought of initializing my arrays using a loop. The only problem is I don't know how to add in hexadecimal. So is there a way to initialize my array without having to input 200 values my self? Also is hexadecimal addition possible without me having to write a function for it?

C# :: Using Linq To Get DriveInfo Of ONE Drive

Jul 23, 2014

I want some simple code which will return only the DriveInfo from one drive. I have the below code but it isn't displaying what I expect it to display, I have a feeling i'm using Linq wrong!

var dname = from n in System.IO.DriveInfo.GetDrives() where n.Name == "F" select n.VolumeLabel;
richTextBox2.AppendText(dname.ToString() + "
");

The above should return the devices VolumeLabel which is in port F.

Instead I get the following:

System.Linq.Enumerable+WhereSelectArrayIterator`2[System.IO.DriveInfo,System.String]

C# :: Detecting CD-ROM Drive And Grab Filepath Of Only CSV File

Jul 8, 2014

I would like the user to insert a CD into their computer and click on an button on my application that allows them to read the CD-ROM and find a specific file type, e.g. csv, and then grab the info in the csv file.

I already have my StreamReader setup grabbing a filepath.

Now I am just wondering...how do I detect the CD-ROM and how do I grab the filepath of the only CSV file on the CD-ROM?

What's behind detecting a CD-ROM and grabbing a specific file type from a CD-ROM?

I heard about DriveInfo

However, that only allows me to detect a drive but not look at it's contents.

C# :: Mapped Network Drive - Deleting Or Moving A File

Sep 16, 2014

Currently I'm trying to do something extremely basic: delete or move a file

I have a mapped network drive (Y) where I have a file I need to move from one folder to another

First was doing the obvious:

System.IO.File.Move("Y:TempFile.txt", "Y:Temp2File.txt");

Not much to go wrong here, right? As long as I have the correct permission to write in the folders and the folders exists, this would normally go smooth. But for some reason it only copies the file. The source file still exists, but it has successfully copied the file to the destination folder. No exceptions has been thrown or anything... but the file still exists in the source directory

I then changed the code to the following:

System.IO.File.Copy("Y:TempFile.txt", "Y:Temp2File.txt");
System.IO.File.Delete("Y:TempFile.txt");
Console.WriteLine("See mommy, no Exceptions");

As expected the file copies correctly, but the delete command is completely ignored. The file is not deleted, but the Console.WriteLine command is called

I'm running the application as the logged in user. The user has permission to delete the file. If I try from Windows Explorer, the file is correctly deleted. Unfortunately my application refuses to delete the file and even worse, it will not even throw an Exception.

UINT32 ip_hex;
//code convert ip to hex
return ip_hex;

Visual C++ :: Using COM Without Registering?

Mar 5, 2013

In a C++ project, I need to call a C# created COM object (as a .dll)

Is there a way to use such a COM object without having it be registered in the registry?

The C# COM dll is just a "go between" our C++ code and a .NET library, there's no "COM contract" of any kind, the COM interfaces change each version. The fact it's COM and needs registration is annoying because it makes it hard to have multiple versions of our software installed (needed under some circumstances) and running at the same time.

I'd like a way to not have any registration at all. And just be able to do a LoadLibrary("c:TheRightPathcom.dll") of the right dll and then get going from there.
