I want to show web report by TCppWebBrowser, the report will be changed any 
time.  So, once I Navigated the page and the report changed, the next 
Navigate will always show the old report (It obviously read from cache). 
How to show the latest report (bypass cache)?

I tried the following methods but failed:
Method 1: Add Refresh() before or after Navigate()
Method 2: set Flags (in Navigate argument) to navNoReadFromCache + 
navNoWriteToCache by the following statement:
                TVariant flags = 4 + 8;
                CppWebBrowser1->Navigate(url, &flags, NULL, NULL, NULL);
Anything wrong?

Thx
Eric

You just mean that a html page has different contents now and a different date ?

Don't know why that does not work.

But think that you have to look in the setings for IE. There
you can order the browser to look everytime for an update.
