Yes PROV_RSA_FULL is supported on W2K. But there were changes to the default encryption method in XP. XP now uses Strong RSA encryption and 128 bit key length. Windows 2000 used (Not Strong) RSA encryption and 40 bit key length.

The string is encrypted on XP but needs to be decrypted on Windows 2000. W2K will try to decrypt using PROV_RSA_FULL but only using a 40 bit key and this is why it fails.

Does anyone know how to force the Crypto API to use standard (NOT Strong) encryption and 40 bit encryption?

Thanks

Property Sheet Problem

Hi All

I have a property page with a tabbed property sheet, which works fine but im a bit stuck on how you get
the values back from each of the property sheets

property sheet is based on the CPropertySheet class, which is not based on CDialog but it provides the same functionality as a dialog.

i wanted to do something like the below, but when ok is called m_c_check doesnt have a value

can anyone point me in the right direction

CEmplSheet EmpSheet("Employment Application");

CEmploymentDlg Empl;
CExperienceDlg Exp;
CEducationDlg Educ;

EmpSheet.AddPage(&Empl);
EmpSheet.AddPage(&Exp);
EmpSheet.AddPage(&Educ);

EmpSheet.EnableStackedTabs(TRUE);

m_pMainWnd = &EmpSheet;

int nResponse = EmpSheet.DoModal();

if (nResponse == IDOK)
{
int i= Educ.m_c_check1.GetCheck();
}
else if (nResponse == IDCANCEL)
{
}

If you are not going to bother to ask a correct question, you mustn't complain about the answers provided. To say that a property page contains property sheets is just nonsensical.

Setting mask for bitmap for CButton

19-Apr-06 12:50

I've added some bitmaps to my resources which I would like to display in buttons, but no matter if I use a CBitmap and SetBitmap or an Icon, a CImageList, I can't set the background transparent.

CImageList::Add says for crMask, "Color used to generate the mask. Each pixel of this color in the given bitmap is changed to black and the corresponding bit in the mask is set to one."

If I use that the background is really black. SetBkColor to CLR_NONE also doesn't work.

I haven't found an example on CP where the mask color is set for a button, maybe someone can help?

Thanks
Andre

Make sure you are both creating the image list with a mask (ILC_MASK) and drawing it with the proper flags (ILD_TRANSPARENT). AFAIK, SetBkColor() only applies when you're drawing non-transparently (ILD_NORMAL) or blending (ILD_BLEND50).

Now taking suggestions for the next release of CPhog...

Which means nothing if you don't tell us which part did not work. Your code has no error checking. What does the Send() method return?

Do you mean it was written using managed code? Then no, you can't use VC 6.
If you mean it was written in native code using VS.NET, then you'll have to change the code so it doesn't use classes that were added after VC 6.

Resizing CButton to fit label

MDI and FormViews

masnu19-Apr-06 10:08

19-Apr-06 10:08

I know how to display a CFormView object by calling it from another view. I need, however, to display a form from an "empty" MDI main frame. The application also contains other types of views.

For example, I would like the user to start the application and then open a data file. The data will then be displayed graphically and used to populate a form.

What is the best way to show a form from the main frame window?

Thanks in advance for your help.
