The scenario is the following
I have a shared storage pointer with my console application Hercules it is defined as LPVOID most of it is displayable characters but some are just hex characters
When try to construct the string with the following CString constructer
CString mystr((LPCTSTR) mysharedptr,34); tracing it in the visual studio debugger
The code goes off into some MFC code that had an assertion specifically ASSERT(FALSE)
Thanks

Show the function and the ASSERT where it goes.
The difficult we do right away...
...the impossible takes slightly longer.

Sorry but you are still not giving us any useful information. What exactly is the content of mysharedptr, and what assertion are you getting? It may well be that a CString is just the wrong class for whatever problem you are trying to solve.

I had a religious holiday over the last 2 days
I do have non display hex characters in the CString
I am begining to think that even though there is a constructer for CString that takes a length it Still is just that a Csting a C type string

CString holds strings. C-type strings.
if you need a container to hold chunks of data which might contain a NULL, CString is the wrong container. you can use a std::vector< BYTE > (or a CByteArray, if you like MFC). or you can roll your own.

As Chris mentioned, think you're trying to use CString for something it's not intended to do. If you need a random byte container (that isn't a string), use something else.
STL has a quite a few to choose from[^].
Additionally, other libraries have other choices...

I am begining to see that CString is a "C" string
Thanks

Well, most data comes down to being bytes... strings just are some set of bytes that are expected to mean something (whether according to ASCII or some other wide character standard)... if you need a generic container, you can't just use something that expects what we'd refer to as a "string".

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

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.
