12-21-2007, 11:44 cricket Joined on 06-22-2007 Posts 11 CoCreateInstance fails (Class not registered) I am using ePrint API (4.5.0.025) to set the "Global Printer Options" (Paper Size). When I am trying to create an "ILEADGlobalPrinterOptions" instance, using "CoCreateInstance", it fails saying "Class not regsitered". HRESULT hRes = CoCreateInstance(CLSID_LEADGlobalPrinterOptions, NULL, CLSCTX_ALL, IID_ILEADGlobalPrinterOptions, (void**)&m_pGlobalPrinterOptions); However, I have NO problem in creating "ILEADGlobalSettings" instance with the following call HRESULT hRes = CoCreateInstance(CLSID_LEADGlobalSettings, NULL, CLSCTX_ALL, IID_ILEADGlobalSettings, (void**)&m_pGlobalSettings); Am I missing something here? Or, is there any other way to set the "Paper Size" and "Page Orientation"? Thanks in advance and Awaiting for an early reply/help.    Report

It is a member of the LEADGlobalSettings object exposed through the GlobalPrinterOptions property. Please see our help code sample for C++, which uses is like this: pGlobalSettings->GetGlobalPrinterOptions()->PaperSize Adnan Ismail LEADTOOLS Technical Support    Report

But, How do we set the "Page Orientation" (Landscape or Portrait)? I don't see any method! Thanks in advance.    Report

You should be able to control the paper properties, including orientation, using the printing application. In version 5 of ePrint, new features that allow you to create custom printers were added. You can control the paper properties of the added printer, including paper size and orientation. Adnan Ismail LEADTOOLS Technical Support    Report
