Raptor数据库异常错误? [英] Raptor Database Exception Error?

问题描述

好吧，我尝试了代码，但起初似乎没有错误，直到尝试调试它为止.也许您可以看到我哪里出问题了?

Ok I have tried the code and at first it seems error free until I try to debug it. Maybe you can see where I have went wrong?

Imports RaptorDB 

Public Class Form1 
Dim rap As RaptorDB.RaptorDB = RaptorDB.RaptorDB.Open("storage", 255, False, INDEXTYPE.HASH) 

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 rap.Set("A1", "123456789") ' to set like a dictionary 
 Dim val As String = "" 
If rap.Get("A1", val) Then 
TextBox1.Text = val 
End If 
End Sub 
End Class

我收到的错误消息是:未处理

The error message I get is:

System.InvalidOperationException was unhandled Message=An error occurred creating the form. See Exception.InnerException for details. The error is: Path cannot be the empty string or all whitespace.

See Exception.InnerException for details. 

错误是:路径不能为空字符串或所有空格.

有人能解决这个问题吗?


提前谢谢！！

The error is: Path cannot be the empty string or all whitespace.

Does anyone have a solution to this problem?


Thank you in advance!!

推荐答案

根据异常的详细情况，以下行

C:\ Users \ Admin \ AppData \ Local \ Temporary Projects \ RaptorDatabase Test \ Form1.vb:第3行

反映异常指针. RaptorDB.Open函数中的第一个参数应该是文件路径，我相信这可能是这里的问题.

As per the exception details the following line

C:\Users\Admin\AppData\Local\Temporary Projects\RaptorDatabase Test\Form1.vb:line 3

reflects the exception pointer. The first parameter in the RaptorDB.Open function should be file path, I believe that could be the issue here.
