Printing HTML progmatically

[Darroll Walsh]

I wrote an app that creates a web page. Now they want to print it out. The problem comes that the settings for everyones printing is set differently, ie margins, header/footer, and if print background is selected. Is there a way to send IE the paramiters I want to print for this page? Thanks in advance. Darroll

I've got a control derived from the browser. My printing code looks like this -

HRESULT hr;

BSTR        header\_BSTR = ::SysAllocString(L"&w&b&b&p");
VARIANT     header\_variant;

VariantInit(&header\_variant);
V\_VT(&header\_variant)   = VT\_BSTR;
V\_BSTR(&header\_variant) = header\_BSTR;

BSTR        footer\_BSTR = ::SysAllocString(L"&d &t");
VARIANT     footer\_variant;

VariantInit(&footer\_variant);
V\_VT(&footer\_variant)   = VT\_BSTR;
V\_BSTR(&footer\_variant) = footer\_BSTR;

long index;

SAFEARRAYBOUND  parameter\_array\_bound\[1\];
SAFEARRAY       \*parameter\_array = NULL;

parameter\_array\_bound\[0\].cElements = 2;
parameter\_array\_bound\[0\].lLbound   = 0;

parameter\_array = SafeArrayCreate(VT\_VARIANT,1,parameter\_array\_bound);

index = 0;
hr = SafeArrayPutElement(parameter\_array,&index,&header\_variant);

index = 1;
hr = SafeArrayPutElement(parameter\_array,&index,&footer\_variant);

VARIANT parameter;
VariantInit(&parameter);
V\_VT(&parameter)    = VT\_ARRAY | VT\_BYREF;
V\_ARRAY(&parameter) = parameter\_array;

hr = \_Browser->ExecWB(OLECMDID\_PRINT,OLECMDEXECOPT\_DONTPROMPTUSER,&parameter,NULL);

if (!SUCCEEDED(hr)) {
    VariantClear(&header\_variant);
    VariantClear(&footer\_variant);
    if (parameter\_array != NULL) {
        SafeArrayDestroy(parameter\_array);
    }
}

This code sets the header and footer for the page and then prints it. The _Browser value points to the IWebBrowser2 interface for the control. If I remember correctly, I found this stuff in an example in the MSDN.
