Hey good input.... couple of followups

1) So if I want to install my application to be accessible for *ALL* users, and specify that changes should be made once per user, and then effect ALL USERS, I'd put it in HKEY_LOCAL_MACHINE, but if I wanted user specific settings, I'd install it in CURRENT_USER, correct?
2) Does each user have their own 'Program Files' directory?

Thanks!

Ok, so when one user installs an application is it available to everyone on the WinXP machine? If not, does WinXP set the permsisions somehow to only allow the user who installed it?

If one user downloads & installs app A, then another user logs in and downloads & installs app A, what happens?

Sometimes yes, other times no. It all depends on the application's installation program.

It all depends on app A's installation and what it does.

Generally, Windows from NT family were designed according to access rights. Every user has got his permissions for perform specific operations e.g. users from Users group don't have permission to (de)/installation.

It's lies in Administrator hands to configure operating system correctly.

I've never seen this API before but the documentation states that the last three parameters are [in, out] parameters. You treat them as out only parameters.

Can you publish the fix? Message board etiquette dictates you should so others can benefit from the thread.

Correct it very simply.

CoInitialize(NULL);
CComPtr spMLang;

DetectEncodingInfo lpInfo[1000];
INT pnScores;//Incorrect code inmust be specify as size of lpInfo (INT pnScore=1000)

wchar_t * wzContent;
if (SUCCEEDED(hr = spMLang.CoCreateInstance(CLSID_CMultiLanguage)))
{
spMLang->DetectInputCodepage(MLDETECTCP_NONE, 0, szContent, &nlen, lpInfo,
npScore); // app crash here
}

CoUninitialize();

I am new to MFC programming. Iam trying to create a dialog box that has to hold data that would run to 3 to 4 pages. I should be able to access all of them by scrolling(horizontal and vertical) the dialog window. I am trying this in a SDI application using VC++ 6.0 Can anyone help / guide me in this regard?
Thanks

Hi,

I would suggest you to use FormView instead of dialog. you can add controls to the view like a dialog and since its derived from scroll view, scrolling is added by default.

Simply derive the view from CFormView. It's one of the last things that AppWizard prompts you with.
