append to file

[ok~forward]

往文件中写数据,每次都要覆盖前面数据，所以
append to file选择false
每次运行结束会弹出对话框问是replace还是cancle
怎样才能不让它弹出对话框而直接覆盖？

which write function are you using?

[ok~forward]

write characters to file

[ian_fung · Accepted solution]

For Write Characters To File.vi, you may save it as another copy (without updating the caller vi).

After that, open it and modify it by wiring advisory dialog? (display:T) to append to file? (new file:F)

That means, when append to file? is set false, advisory dialog will not be prompted. 

PS: you may try download it at my site too under File IO

不好意思，不是很明白

是说把程序另存一下然后再打开，连线 advisory dialog? (display:T) to append to file? (new file:F)吗？

能否截个图？谢谢

Precisely!

[ok~forward]

我试过这种方法，但是刚开始它还是会弹出保存文件的提示框，如图，不知道是不是您的意思。

我是想让它不要弹出任何提示框自动覆盖保存的

You have to ensure that the file path is valid (not empty) even for the first time...
