Crystal Report報表開發(八)_The maximum report processing jobs limit configured by your system administrator has been reached.

 

最近由於需要在大量rpt檔案中去search是否有要替換的關鍵字

簽名字有一些人員職務調整就更換人員名稱

但尷尬的是報表檔裡面人名是直接寫死的.....>~<

而誕生需要寫這段程式的小需求

為何要寫程式盤點?

因為rpt檔案數量大概有300個吧每一個都一個個打開來盤點大概2~3天就過去了

而且下次又有類似需求

你要花一樣多時間甚至更久......

在此用vs2008來開發 水晶報表的小程式

創建好的winform專案

直接跑

那突然有報一個錯誤

The maximum report processing jobs limit configured by your system administrator has been reached.

機上就是記得ReportDocument物件doc

迴圈尾端記得.Close()跟.Dispose() 把記憶體資源給釋放乾淨即可。

太久沒用又稍微忘記了
