摘　　要：在应用程序设计中文件的保存及打开常采用文件对话框的形式。LabVIEW提供了丰富的文件处理函数,其中就包括文件对话框;但该文件对话框无法进行取消操作,这给应用程序带来了一些隐患。针对此问题,分析了LabVIEW文件对话框函数的功能及特性,对LabVIEW文件对话框无法进行取消操作进行了阐述。在编程实践中设计开发了保存文件对话框子VI,解决了LabVIEW文件对话框无法进行取消操作的缺陷。The document dialog box is often adopted when saves or opens documents in applied program design. The LabVIEW provides abundant documents processing function, and a document dialog box is included among them. But the document dialog box can not be canceled, this brings some problems in applications. The function and characteristic of the LabVIEW document dialog box were analyzed, the document dialog box sub Ⅵ that saves the files was designed in program practice, which solves the bug that the document dialog box in the LabVIEW can not be canceled.
