Borland C++ Builder using Delphi Forms question
Hi All ,
I am damn new to C++ and delphi and am asked to do this little project. I need help. I am using a web browser(CppWebBrowswer1) and call the navigate method , CppWebBrowser1->navigate(url).This url is an exception page(html page) on a mobile vehicle and is accessed as the vehicle comes in range of the access point. This HTML page is generated bu software running ont he vehicle. MY PROBLEM -- I print the page directly CppWebBrowser1->ExecWB(Shdocvw_tlb::OLECMDID_PRINT,Shdocvw_tlb::OLECMDEXECOPT_DONTPROMPTUSER); onDocumentComplete(..or OnNavigateComplete2). The problem is I need to check if there is a HTML page because, at times , i get this HTTP 404(page not found print out).That is the application tries to print a page faster than it is generated by the software on the mobile vehicle. I need to be able to some how check to see if the page exists( if the server on the mobile vehicle returns HTTP 404), and if not, not to print.

The DocumentComplete event never worked correctly for me. I use the ProgressChange event instead:
Code:
procedure TfrmMain.WebBrowserProgressChange(Sender: TObject; Progress, ProgressMax: Integer); begin if Progress = -1 then bReadPage := true; end; Elsewhere in the code, I have: Code:
bReadPage := false;
WebBrowser.Navigate('http://www.foo.com/');
while not bReadPage do
Application.ProcessMessages;
This has always worked for me.
