    分享成果，隨喜正能量】人生就不會事事如意，樣樣隨心，學會寬慰自己，懂得安慰自己。世上就沒有最好，何必要強迫自己，盡心了，無論結果如何都可以。人生難料，難料人生。人吧，融入這個社會很容易，理解這個社會很難，懂這個社會里的人更是難如上青天。??。

    跟我學VBA，我這里專注VBA, 授人以漁。我98年開始，從源碼接觸VBA已經20余年了，隨著年齡的增長，越來越覺得有必要把這項技能傳遞給需要這項技術的職場人員。希望職場和數據打交道的朋友，都來學習VBA,利用VBA,起碼可以提高自己的工作效率，可以有時間多陪陪父母，多陪陪家人，何樂而不為呢？

    這講我們繼續學習64位Office API聲明語句第92講，這些內容是MS的權威資料，看似枯燥，但對于想學習API函數的朋友是非常有用的。

    當學員學習到高級階段，如果引用API，這個資料可以直接查到64位寫法。大多數情況下我們是將低版本的程序文件升級到高版本，這時您就不必為如下的錯誤提示所困擾了：
