Hi there, I am new to the programming scene. I am a Digital Forensic Investigator with the Digital Forensic Laboratory at The Directorate For Priority Crime Investigation; within the South African Police Services.
I was recently assigned to do research and analysis on compromised Verifone POS-devices. On some of the devices we do manage to extract data, which is encrypted. I investigated some of the tools the criminals use in the process.
On the malwr.com site the encryption tool PasswordGenerator.exe was uploaded and can be downloaded from there for analysis. This tool uses MACTripleDES PADRight encryption.
Is there maybe anyone that can assist me to create a tool to decrypt the data from the devices. The PWG creates an init.dat file that is uploaded to the POS device which encrypts the data that is captured and then decrypted after being downloaded with The VeriFoneDownloader.exe and then the .vfd-file is decrypted using the VeryFoneViewDataNew.exe. When the correct password is entered and the file decrypted it is saved as a .dfv-file.
All the .exe files are uploaded at malwr.com. I will upload an encrypted and decrypted file as well. (201404221348.vfd and 201404221348.dfv)
If there is anyone that can assist it would be highly appreciated.

Design and implement a class for binary trees, following the specification at the following URL http://www.cs.colorado.edu/~main/chapter10/bt_class.h
Your design should use a dynamic array to hold the data from the nodes in the same way that a complete binary tree is usually represented. However, these binary trees do not need to be complete. Instead, you should have a second private member variable that is a dynamic array of Boolean values called is_present. The is_present array indicates which nodes actually exist in the tree. For example, if the tree has a root node, then location is_present[0] is true. If the root has a left child, then is_present[1] is true. If the root has a right child, then is_present[2] is true.

Hi
I am used to figuring character formatting from the mainframe world where everything is a byte, towards that and I would like to use courier new in my rich edit.
can I use
EM_SETCHARFORMAT setting courier new
of course I would probably have to use CClientDC to get the device context of the rich edit
and then GetCharABCWidths
Does this make any sense ?

Not really.
Everything on a PC is also a byte (or a word ...). The only time the format of a character has any real relevance is when you display it on some output device. So when writing to your device context, you must first create a font and select it into the DC. See https://msdn.microsoft.com/en-us/library/w6196kz3.aspx[^] for some more details. See also http://www.functionx.com/win32/Lesson15.htm[^] for a sample using Win32, but you should be able to get enough information to use that in MFC.

I think courier new all the characters are the same width I'll read the doc
Thanks

You should use a try/catch block to catch exceptions that occur in such circumstances, and/or check the status of any file access calls.
|
|
|
|
|
1. You should handle the exception.
2. You can write a method to check connection (through ping).

If you share which API you are using for file I/O then you'd get answer more accurately.
Did you used std::fstream or some other API?

I want a code of c code
which can take million integers as input,
sort them (bubble or quick or selection sort).
It should display time taken to sort first 10 integer, then for first 100 integer, then for 10000 and total.
Please help me soon I have very less time to complete my project.

Sorry, CodeProject does not provide code to order, especially for homework questions.

Well then, you'd better hop-to-it and get writing then don't you?
There's countless examples of sorting code on the web. If you cant even be bothered to search for them, and instead ask to be spoon-fed,you're not going to enjoy programming much - it's an occupation that required copious amounts of research.
Also, you might wish to edit your question to remove your email address - you'll get email notifications if someone replies anyway - providing your email just provides opportunity for others to inconvenience you.

Hello,
I am trying to get all available logical drive information using WMI services. If a partition is under extended partition, I am getting wrong startingOffset although getting correct startingoffset in case non extended partition.
Please suggest....
|
|
|
|
|
In the extended partitions the meaning of partition table entries are different from that of standard partitions.
You may want have a look to this[^] MS article.

Hi
My code for Create (of a dialog box fails) in MFC base code specifically the line in bold
when I try to Create for a DialogBox
I have DECLARE_DYNAMIC and IMPLEMENT_DYNAMIC in the respective sources though I don't think that is a issue one way or a other
Don't know why
main_app->myshow_storageptr = new Show_storage();
main_app->myshow_storageptr->AssertValid();
main_app->myshow_storageptr->Create(IDD_DIALOG6,NULL);
MFC code from wincore
void AFXAPI AfxHookWindowCreate(CWnd* pWnd)
{
_AFX_THREAD_STATE* pThreadState = _afxThreadState.GetData();
if (pThreadState->m_pWndInit == pWnd)
return;
<pre>
if (pThreadState->m_hHookOldCbtFilter == NULL)
{
pThreadState->m_hHookOldCbtFilter = ::SetWindowsHookEx(WH_CBT,
_AfxCbtFilterHook, NULL, ::GetCurrentThreadId());
if (pThreadState->m_hHookOldCbtFilter == NULL)
AfxThrowMemoryException();
}
ASSERT(pThreadState->m_hHookOldCbtFilter != NULL);
ASSERT(pWnd != NULL);
ASSERT(pWnd->m_hWnd == NULL); // only do once
ASSERT(pThreadState->m_pWndInit == NULL); // hook not already in progress
pThreadState->m_pWndInit = pWnd;

What type of object is Show_storage?
What does Create() return?
Where is your code called from, or what is it in response to?
"One man's wage rise is another man's price increase." - Harold Wilson

A CDialog
Create never return it aborts causes an an exception
In the assert highlighted in bold
|
|
|
|
|
The assert fails because the CWnd* does not point to an object that contains a valid Window handle. Something in your code has not been initiailised correctly, or you are calling Create from outside of a Window class. What class is Show_storage?
