FULL代码： PASTEBIN - LINK [ ^ ]



我不知道发生了什么

我已经尝试将try语句放在每个代码上的子代码:(

请大家帮帮忙。

FULL CODE: PASTEBIN - LINK[^]

I don't know what is happening
I already try to put try statement on every sub on the code :(
Please help guys.

推荐答案

我对VB.Net并不是很熟悉 - 但是查看代码，你有3个interops声明 - 我会在调用/使用这些interop之前立即对你的程序进行一些跟踪，这样你就可以检查传递的值



显然你可以使用断点，跟踪，将其缩小到特定的代码行，你的生活会更容易

Im not really familiar with VB.Net - but looking at the code, you have 3 interops declared - I would put some tracing into your program immediately before these interops are called/used so you can check the values being passed

Obviously if you could use breakpoints, tracing, to narrow it down to a specific line of code a bit your life would be easier

来吧，问题究竟在哪里，你现在尝试了什么？当我在Google上搜索System.Number.StringToNumber和FormatException时，我得到了很多结果。例如。 http://support.microsoft.com/kb/942460 [ ^ ]描述了一个错误。但是：您确定用户以您所在地区可接受的格式输入数字（葡萄牙语或巴西语左右 - 在任何情况下：不是美国英语）设置？

Come on, where is the problem exactly, what did you try upto now? When I do a Google search for System.Number.StringToNumber and FormatException, I get many results. E.g. http://support.microsoft.com/kb/942460[^] describes a bug. But: are you sure that the user entered numbers in a format which is acceptable for your regional (Portugese or Brasilian or so - in any case: not US English) settings?
