Hi Lancaster,
Thanks for your reply! I've research the essay you posted, and I can encrypt & decrypt a CString like:
[Head file]
CCrypto crypto;
CByteArray arBytes;
[cpp file]
void CEncryptionDlg::OnBnClickedButton_Encrypt()
{
crypto.DeriveKey(_T("ABCD"));
CString sPassword=_T("Hello");
crypto.Encrypt(sPassword,arBytes);
}
void CEncryptionDlg::OnBnClickedButton_Decrypt()
{
CString strDecrypted;
crypto.Decrypt(arBytes, strDecrypted);
MessageBox(strDecrypted, _T("Notify"), MB_OK);
}

And then, I want to save the sPassword but the type of data is CByteArray between the encrypt() and decrypt().
If I want to save the CByteArray in a txt file, I gotta transform into CString.
It failed it...

my code:
[Head file]
CCrypto crypto;
CString sContent;
[cpp file]
void CEncryptionDlg::OnBnClickedButton_EncryptString()
{
crypto.DeriveKey(_T("ABCDEF"));
CString sPassword=_T("Hi");
CByteArray arBytes2;
crypto.Encrypt(sPassword,arBytes2);
CString str2(arBytes2.GetData()); //CByteArray to CString
sTest=str2;
}
void CEncryptionDlg::OnBnClickedButton_DecryptString()
{
CByteArray byteArr;
//CString to CByteArray --- start
BYTE *pByteArray = (PBYTE)(LPCTSTR)sTest.GetBuffer();
byteArr.SetSize(sTest.GetLength());
memcpy(byteArr.GetData(), pByteArray, sTest.GetLength());
//CString to CByteArray --- end

CString sDecrypted;
crypto.Decrypt(byteArr, sDecrypted);
MessageBox(sDecrypted, _T("Notify"), MB_OK);
}

But the sDecryprted is NOT "Hi" I want to get :(
Could someone give me some suggestions?
Thanks!!!

Thanks for your suggestion! I finds my question!! So appreciated for your help!!!

Thanks for your reply!
Sorry! I don't specify exactly.
In local machine, I can download the correct file from the server first time.
If the file changes the content, I CAN'T update the correct file again in local machine.
in local machine, it will produce the oldest file which is I first download, if I press the GetFile button afterwards.
Thanks!

I think whether I can call a existing program through lpName(in my case, it's the "Test program")?
But I cannot find the relative functions...

Dear du[DE]:
Thanks for your response, but I still don't have a idea...
Would you specify it concretely?
Thank you!!

I'm so sorry for spending your a lot of time.
I have tried what you taught me. However, it's similar like the SetRedraw().
Furthermore, I find a new thing(maybe it's the real problem for this case) when the application run and I opened the explorer.exe(ex. any folder), the application became abnormal display, too.
Is there any notification can retrieve the event?
In addition, if you will, I can sent my code for you.
Thank you!

I try it:

void TabDlg::OnActivate(UINT nState,CWnd* pWndOther,BOOL bMinimized )
{
switch(nState)
{
case WA_CLICKACTIVE:
case WA_ACTIVE:
case WA_INACTIVE:
{
m_tab.SetRedraw(true);
}
break;
default:
break;
}
CDialog::OnActivate(nState,pWndOther,bMinimized);
}

, but the abnormal display was still alive :(
Only when I clicked the application anywhere, the display became normal
(by WA_CLICKACTIVE).
Did I miss something@@?
thanks!!

I have read the WM_ACTIVATE form your link, but I still don't understand how to use it...
Would you teach me how to use it, maybe a easy example, please.
Thanks for your help!!

Thank you, SA!! there methods can solve the abnormal Tab.
Because I don't know when the user redraw the desktop of OS(I guessed what causes the abnormal), I scanned the application by OnTimer function (0.5 sec),
but it let my application glistened.
I only wanted to redraw the Tab Page, so I used the SetRedraw() to reduce the redraw area,
but it still glistened obviously T_T
I think if there is a function that could judge the desktop of OS has redraw, and then I can SetRedraw() if the OS has redraw.
Thanks a lot!!

Yes, you are right!
That situation happened in my application!
How can I solve this problem?
Thank you!

thanks for your reply again!
Sorry, I don't know what the "half-hide" is,
so I can't understand what you said in step2.
Could you illustrate clearly?
Appreciation!!

I tried the test which you said, and it's normal. The abnormal display appears only if I press Ctrl+Alt+Del or opened the another application with UAC. I don't know why...

thanks for your reply, Kryukov! I have tried the way which you said, and I found it will happen in Ctrl+Alt+Del, too... But the other cases didn't abnormal@@

Thank you,merano.
I will study it!!

Very thank you, Beyer!!
I can change the color by your method!
But the style became very traditional@@
Like this image http://ppt.cc/iAUU
(I compared the ProgressBar before and after Using the SetWindowTheme)

Is it normal?
I want to know whether or not I can keep the normal style, and just change the color.
I'm so sorry that it spent you so much time >_<
Thanks AGAIN!!

Mr.nv3, you let me learn a lot about that!
Thank you, too!!

Thanks for your reply, Beyer!
I have linked the uxtheme.lib and include the uxtheme.h in my xxxDlg.cpp,
and want to add the SetWindowTheme funtion in CxxxDlg::OnInitDialog().
but I created the ProgressControl by Wizard. There was not handle.
How can I create the handle about ProgressControl?
Thank you :)

Thanks for your reply, merano!
I have added the code you wrote in my code,
and in the CMyApp::InitInstance(), I use your code instead of the original code:

INITCOMMONCONTROLSEX InitCtrls;
InitCtrls.dwSize = sizeof(InitCtrls);
InitCtrls.dwICC = ICC_WIN95_CLASSES;
InitCommonControlsEx(&InitCtrls);

But the bar is still green... Did I miss something?
Thank you!!

Thanks for your reply, Beyer!
So the manner cannot use in MFC, right?
>_<

Thanks for your reply again!

Thanks for your reply, Wombaticus!
But I don't know where the Application.EnableVisualStyles is.
Is it a code or attribute of Progress Control?
Thank you!!
