我有一个奇怪的问题，我试图从控制台应用程序打印 microsoft word 中的特定页面范围，我看到奇怪的结果，我假设这是我在指定页面范围时做错的事情。

看来，在我打印一个页面范围并获取 word 文档中的总页数之后，这个数字在我打印特定范围后会有所不同。另一个奇怪的事情是，这在调试模式下有效，但在发布模式下无效。

前任。Word 文档由 2 页组成 打印第 1-1 页。获取页数返回2

打印第2-2页获取页数返回1

下面的代码用于打印一系列页面：

int CWordComm::PrintAndCloseActiveDocument(int iNumOfCopies, short nTray, int pageNumber)
{
    // Convenient values declared as ColeVariants.
    COleVariant covTrue((short)TRUE), covFalse((short)FALSE), covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);

    _Document oActiveDoc = m_oWord.GetActiveDocument();

    if(!this->m_szOutputFilename.IsEmpty())
    {
        //If we are outputting the document to a file then we need to print a single page at a time
        //This is because of a limitation on the ikonprinter/requisition printer side that can only handle
        //one page at a time
        // Print out to file
        CString szCurrentPage, szPrintRange;
        szCurrentPage.Format("%d", pageNumber);
        szPrintRange.Format("%d", PRINT_FROM_TO);  //PRINT_FROM_TO is #define PRINT_FROM_TO 3

        COleVariant printRange(szPrintRange, VT_BSTR);
        COleVariant currentPage(szCurrentPage, VT_BSTR);

        sprintf(m_szLogMessage, "Printing page %d of requisition", pageNumber);
        LogMessage(m_szLogMessage);

        oActiveDoc.PrintOut(covFalse,          // Background.
            covOptional,           // Append.
            printRange,             // Range.
            COleVariant(szFileName,VT_BSTR),  // OutputFileName.
            currentPage,           // From.
            currentPage,           // To.
            covOptional,           // Item.
            COleVariant((long)1),  // Copies.
            covOptional,           // Pages.
            covOptional,           // PageType.
            covTrue,               // PrintToFile.
            covOptional,           // Collate.
            covOptional,           // ActivePrinterMacGX.
            covOptional            // ManualDuplexPrint.
            );
    }
    else
    {
        // Print out to file
        oActiveDoc.PrintOut(covFalse,          // Background.
            covOptional,           // Append.
            covOptional,           // Range.
            COleVariant(szFileName,VT_BSTR),  // OutputFileName.
            covOptional,           // From.
            covOptional,           // To.
            covOptional,           // Item.
            COleVariant((long)1),  // Copies.
            covOptional,           // Pages.
            covOptional,           // PageType.
            covTrue,               // PrintToFile.
            covOptional,           // Collate.
            covOptional,           // ActivePrinterMacGX.
            covOptional            // ManualDuplexPrint.
            );
    }

    //Get the number of pages in the word document
    iNumPages=GetActiveDocPageCount();

    //omitted code
}

        return atoi(sPropValue);

    }
    catch(...)

    }
}

问题

有什么明显的我做错了吗？如果我想打印一系列页面，我应该以不同的方式与 word 交互吗？

如果它在调试模式下工作正常，我建议您将值（例如页数、正在打印的页面等）写入文本文件。将调试日志输出与发布日志输出进行比较。这是一个可能对您有所帮助的链接。该链接不在 C++ 中，但可能会以正确的方式指导您。

事实证明这是某种时间问题。我在打印文档之后和计算页数之前休眠了 500 毫秒，现在我一直得到正确的结果。

当我调试时，它基本上是在做同样的事情。
