TCppWebBrowser print functionaliy
Luca Picello
The only help I've found googling and in the online help is:

Any further?
Thank you,

I did find some other good pieces of code however they do not work >:(
// DO NOTHING
CppWebBrowser1->ExecWB(::OLECMDID_PRINT, ::OLECMDEXECOPT_DONTPROMPTUSER);
// FROM http://www.codeproject.com/miscctrl/wbp.asp

LPDISPATCH lpDispApp = CppWebBrowser1->Application;
if(lpDispApp)

// Get the HTMLDocument interface.
LPDISPATCH lpDispDoc = CppWebBrowser1->Document;
if (lpDispDoc != NULL)
{
// Get the IOleCommandTarget interface so that
// we can dispatch the command.
LPOLECOMMANDTARGET lpTarget = NULL;
if (SUCCEEDED(lpDispDoc->
QueryInterface(IID_IOleCommandTarget,
(LPVOID*) &lpTarget)))

Prntr->EndDoc();

compiling the whole project at http://www.codeproject.com/miscctrl/wbp.asp with
Visual Studio 2003 it runs perfectly. Then I tried to create a DLL to import
functions capabilities to my borland application. Unfortunately I've got no
results :-(
Any help is REALLY appreciated

Then use the code that I suggested.

Ah... Strange. Here it works ok. What are the problems ?
Errormessages ?

Using:
TVariant outvar;
CppWebBrowser1->ExecWB(OLECMDID_PRINT, 0, NULL, outvar);
I'd like to understand outvar's meaning but there is no documentation.
I'm using Borland C++ Builder 6 with service pack 4 on WindowsXP pro (with
latest updates).
I believe to a bug not in my code... >:(
What environment do you use?
thanks,

The Small example. All successfully work, but does not print footline(only headline). Why, I do not know. Where there is mistake?
Code:
void __fastcall TForm1::PrintButtonClick(TObject *Sender)
{
SAFEARRAYBOUND psabBounds[1];
SAFEARRAY *psaHeadFoot;
// Initialize header and footer parameters to send to ExecWB().
psabBounds[0].lLbound = 0;
psabBounds[0].cElements = 2;
psaHeadFoot = SafeArrayCreate(VT_VARIANT, 1, psabBounds);
VARIANT vHeadStr, vFootStr;
long rgIndices;
VariantInit(&vHeadStr);
VariantInit(&vFootStr);
// Argument 1: Header
vHeadStr.vt = VT_BSTR;
vHeadStr.bstrVal = SysAllocString(L"This is my header string.");
// Argument 2: Footer
vFootStr.vt = VT_BSTR;
vFootStr.bstrVal = SysAllocString(L"This is my footer string.");
rgIndices = 0;
SafeArrayPutElement(psaHeadFoot, &rgIndices, static_cast<void *>(&vHeadStr));
rgIndices = 1;
SafeArrayPutElement(psaHeadFoot, &rgIndices, static_cast<void *>(&vFootStr));
// SAFEARRAY must be passed ByRef or else MSHTML transforms it into NULL.
TVariant vArg;
VariantInit(&vArg);
vArg.vt = VT_ARRAY | VT_BYREF;
vArg.parray = psaHeadFoot;
WB->ExecWB(Shdocvw_tlb::OLECMDID_PRINT, Shdocvw_tlb::OLECMDEXECOPT_DONTPROMPTUSER, &vArg, NULL);
VariantClear(&vHeadStr);
VariantClear(&vFootStr);
if (psaHeadFoot) {
SafeArrayDestroy(psaHeadFoot);
}
}

With copy and paste of your source it does not work too.
No pages are printed :-(
Maybe there are some registry settings to check.

it is related to the webpage I am trying to load.
using any website (like www.microsoft.com) it works perfectly.
thank you all for your good suggestions

It does not print. just update the page in CppWebBrowser1 control.
Neither calling ChDir before.
ChDir( "z:/report/" );
CppWebBrowser1->Navigate("file://z:\\report\\report2.html");

What would ChDir() have to do with printing ?

> CppWebBrowser1->Navigate("file://z:\\report\\report2.html");
Why would the contents of the html file have to do something with printing?

What happens when you do proper forward slashes?
CppWebBrowser1->Navigate("file://z:/report/report2.html");

Luca, you need to wait for the Document complete event after any call to
navigate!
void __fastcall TmainForm::CppWebBrowser1DocumentComplete(TObject *Sender,
LPDISPATCH pDisp, VARIANT *URL)
{
if (Printing)
{
CppWebBrowser1->ExecWB( Shdocvw_tlb::OLECMDID_PRINT,
Shdocvw_tlb::OLECMDEXECOPT_DONTPROMPTUSER);
}
}

My error was not using CppWebBrowser1DocumentComplete method but:
CppWebBrowser1->Navigate(file://z:\\report\\report2.html);
while(CppWebBrowser1->Busy)
Application->ProcessMessages();
but now I know it is obviously wrong!
Thank you very and very much Martin.

and store its configuration in the registry.
Or in any way the printer configuration can be stored/restored from the application.
Any suggestion is really appreciated
Thank you,

Have a look at the keys in \\Software\\Microsoft\\Internet
Explorer\\PageSetup. I usually save these settings, apply what I need for my
app, then restore the old values.

are there no way to get/set it only for the application?
thanks

And if your user is running any other application - well, good luck to
them.
I really hope there's a better solution than this.

Yes, that may be a problem. Actually I do this after my user clicks on the
print button:
... OnPrintClick()
{
SaveOldRegSettings();
ApplyMySettings();
Print();
RestoreOldSettings();
}
So the chance for a collision of two apps is very small.
If anybody knows a better way, please let me know.

No, these are per user global settings for Internet Explorer. The key is in
HKEY_CURRENT_USER. I don't know of any other way and it worked well for my
application.

The first way:
Show the standard window of the dialogue, install the global hook, install their own parameters, move dialog off screen and print.
The second way:
PrintTemplates
