It could be but ... CryptAcquireContext() does not raise this error, it succeeded. It's CryptDecrypt() which fails.

Naturally this function tries (would?) to decrypt data using the AT_KEYEXCHANGE key obtained with CryptGetUserKey() from the context acquired from the smart card.

According to MSDN:

"The CryptGetUserKey function retrieves a handle of one of a user's two public/private key pairs..."

If I'm not wrong CryptoAPI CryptEncrypt()/CryptDecrypt() should use the public key to encrypt and the private key to decrypt, but decrypting with the private key from the smart card fails.

Changhing the key type to AT_SIGNING when retrieving the key pair with CryptGetUserKey() has no effects (and it has not sense for me. I don't want to sign a piece of data with the private key. I want decrypt a piece of data with it ).

Compression algorithms using MMX extensions

I am looking for a compression algorithm library (zlib or similar) which uses the Intel MMX extensions in order to get the best performance. Any suggestions?

I'd take a pretty big guess that the limiting factor on compression performance is how fast the data can be pulled in from and written to the disk, and on the performance of the memory buses, not on the core processing performance of the CPU. ZIP deflate isn't a particularly CPU-intensive algorithm.

2. I created a new Button in the -works-

What I want is to fill the EditBox whith values calculated in the Doc.h by clicking the fill button (Btn with the green point).
Every click on the Fill button another value in the EditBix !
The On Fill function is in the Doc.cpp !
But this isn't working !

Pleeese help me, this prob. is really drivin' me crazy ;(

Many, Many Thanx for your help.
Best regards

Yes, many people could help you. All that Nelek's asking is that you clean up your post (not by creating a separate post) by removing all but the relevant lines of code. Folks here help for the fun of it so asking them to read through pages of unnecessary code is a sure way to get ignored.

then i included the MainFrm.h in doc.cpp now i get :
: error C2660: 'GetParent' : Funktion akzeptiert keine 0 Parameter
: error C2227: Der linke Teil von '->SetMyToolBarEditText' muss auf Klasse/Struktur/Union zeigen

GetParent needs a hwnd but how can i get one ?

Best regards

P.S.: Are there tuts our there which explain the Prob whith an edit in a toolBat ? I can only find 1 or 2 tuts which discribe the usage of comboboxes. Or are ther perhaps sources / code snippets ???

That depends on which version you are using. To access the frame from within your CDocument-derived class, then you would need to use:

((CMainFrame *) AfxGetMainWnd())->SetMyToolBarEditText("blabla");
