can someone pls help me!!

I am tring to diplay all file in a directory into a text box, but i am getting nothing i dont know what i am doing wrong..I mae a new project and got it to display a txt box, and tried to display fils in it but didnt work

void PlayerDlg::DoDataExchange(CDataExchange* pDX)
{
DDX_Text(pDX, IDC_AUDIOLIST,m_AudioList);
}

BOOL PlayerDlg::OnInitDialog()
{
CDialog::OnInitDialog();

CFileFind finder;
bool bFound;
CListBox *m_AudioList = (CListBox*)this;

static const TCHAR szFileToFine[] = _T("d:\\songs\\*.mp3");
bFound = finder.FindFile(szFileToFine);
if(bFound) {

bFound = finder.FindNextFile();
m_AudioList->AddString(finder.GetFileName());
while(bFound) {
bFound = finder.FindNextFile();
if(bFound) {
m_AudioList-> Frown | :(

AddString(finder.GetFileName());

}
}}}

void PlayerDlg::DoDataExchange(CDataExchange* pDX)
{
DDX_Text(pDX, IDC_AUDIOLIST,m_AudioList); <-- what is m_AudioList?? Calling DDX_Text()? Why?
}

BOOL PlayerDlg::OnInitDialog()
{
CDialog::OnInitDialog();

CFileFind finder;
bool bFound;
CListBox *m_AudioList = (CListBox*)this; <-- Casting a dialog pointer to a CListBox pointer...bad

static const TCHAR szFileToFine[] = _T("d:\\songs\\*.mp3");
bFound = finder.FindFile(szFileToFine);
if(bFound) {

bFound = finder.FindNextFile();
m_AudioList->AddString(finder.GetFileName());
while(bFound) {
bFound = finder.FindNextFile();
if(bFound) {
m_AudioList-> AddString(finder.GetFileName());

}
}}}

Maybe try making m_AudioList a member variable of the dialog class:

CListBox m_AudioList;

Then use it something like this:

void PlayerDlg::DoDataExchange(CDataExchange* pDX)
{
    DDX_Control(pDX, IDC_AUDIOLIST, m_AudioList);
}

BOOL PlayerDlg::OnInitDialog()
{
    CDialog::OnInitDialog();

    static const TCHAR szFileToFine[] = _T("d:\\songs\\*.mp3");

    CFileFind finder;
    bool bFound = finder.FindFile(szFileToFine);
    while (bFound)
    {
        bFound = finder.FindNextFile();
        m_AudioList->AddString(finder.GetFileName());
    } 
}

It has problem.

And also this line.
How did you make listbox control why you dont declare a variable for it and use of it?

Restricting security in web browser control

drummer14-Dec-07 11:35

14-Dec-07 11:35

Hello everyone,

I have an application that uses the web browser ActiveX control that displays content from other users. For security, I would like to restrict the control to only displaying the content by disabling scripting, embedded controls, etc. I'm sure this is possible, but I have not figured out how to do this.

Thanks!

Unable to load dll on computers which do not have Visual Studio installed

Member 408492814-Dec-07 9:46

Member 4084928

14-Dec-07 9:46

I created a program using visual basic. For some functions the program accesses a dll which was created using visual c++. When the program is run on a computer that does not have visual studio installed, functions which make calls to the dll generate an error:

Unable to load DLL 'filename.dll': This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1).

Reinstalling the application does not help, and when the program is run on a computer that does have visual studio installed, calls to the dll work as expected without generating any type of error. I even attached and installed all the latest Visual C++ Runtime Libraries, and still no luck.

Is there some component that is installed with Visual Studio that I need to attach to my program installation? Is there some way I can create or access the dll such that it does not need this component?

You're probably missing the CRT. You could statically link

CryptoAPI: Send a challenge to a smart card

Nyarlatotep14-Dec-07 5:28

Various smart card certificates are imported into the system store. When a smart card is inserted into the reader, the user have to select his certificate from the list of certificates in the sistem and then insert the PIN.
To verify that the certificate selected from the system store correspond to the smart card currently in the reader I try to send a challenge to the smart card (GemPlus CSP)

- A crypto context from the certificate selected from the system store is acquired.
- A crypto context from the smart card in the reader is acquired.
- A challenge is created with random data (CryptGenRandom()).
- The public/private key pair is obtained from the certificate in the system. (CryptGetUserKey(AT_KEYEXCHANGE)).
- The challenge is encrypted with the previous public key from the certificate in the system store (CryptEncrypt()).
- The public/private key pair is obtained from the smart card (CryptGetUserKey(AT_KEYEXCHANGE)).
- The encrypted challenge is decrypted with the smart card (CryptDecrypt(AT_KEYEXCHANGE)) which should use his private key.

But when CryptDecrypt() with the crypto context of the smart card is called, error NTE_PROVIDER_DLL_FAIL (0x8009001D) is obtained.

Where is the error ? NTE_PROVIDER_DLL_FAIL is an error raised when a context is acquired, according to the documentation, but it seems to have no relation with Crypt/Decrypt !

Thanks

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 ).

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.

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.

But what is not working? Have you used the debugger to step through the code? What happens in SetMyToolBarEditText()?

Hi,

first i get a not declared identifier at ((CMainFrame*)GetParent())->SetMyToolBarEditText("blabla");

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
Croc

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");
