On the project property's 'Configuration' tab, specify 'use MFC in a static library'. This will remove dependencies on the MFC dlls; you won't have to redistribute those with your .exe. Any third-party dlls you might use will still have to be distributed with the app. Place them in the same directory as the .exe when distributing.

If you want to get a little more professional, you can put together an installation package (.msi) that can create shortcuts to the user's Programs directory, creates any necessary registry entries, etc. VS05 supports this - it's pretty straightforward.

Hello

The best is to use a PDF Printer Driver.
it is a virtual printer that you install on your computer and you call when you want to print your document.

Somes are free .. and somes not.

(PDF995, PDFCreator, Amyuni, ...).

dynamic_cast fails

There is an Edit control on the dialog. The ID is IDC_EDIT.

In CMyDialog::OnInitDialog(), I do this ...

CEdit* pEdit = dynamic_cast<CEdit*>(GetDlgItem(IDC_EDIT) /* = some valid address */);
if(!pEdit) {
  // Error;
}

The CWnd* returned from GetDlgItem failed to convert to a CEdit*. But isn't CEdit derived from CWnd? Confused | :confused:

Hi Maxwell,

Yes, but GetDlgItem does not always return a CEdit pointer so the dynamic_cast runtime check fails. Have a look at the following document:

Inside MFC: Handle Maps and Temporary Objects[^]

Essentially... when GetDlgItem cannot find a permanent object in the MFC CHandleMap it will return a pointer to a CTempWnd object. So your code fails to dynamic_cast from CTempWnd to CEdit.

As an experiment you should add a CEdit member variable to your class for IDC_EDIT. This will cause the CHandleMap to have a permanent handle. Now your code will magically work. Smile | :)

You get the size information for "DWORDSample" and then try to retrieve the value of "StringSample"! What is the correct name of your value variable?

First of all, your variable "dw" is not initialized when you're calling RegQueryValueEx. Also, you set the address for the data buffer to NULL.

I think that is the correct call to obtain the size of the variable before getting its value.
