This article mainly introduces how to use app.path, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

When the program opens the file, if it does not specify the directory of the file, it will open the file of the "current directory", but the current directory is often changed. If you specify a directory, then when you install the program in the future, the opened file must be installed in the specified directory, which is relatively inflexible. This problem can be resolved using app.path.

Apppath solution

The way to solve the above problems is to open the file by the following methods:

OpenApp.Path+ "\" + "File name" For ┅

And put the opened file in the same directory as the executable file, because App.Path represents the directory where the application is located. However, there is one thing to pay special attention to when using App.Path. When App.Path is in the root directory, the rightmost character of App.Path is "\", such as "c:\", but if App.Path is not in the root directory, the rightmost character of App.Path is not "\", such as "d:\ kj\ app1", so to get the full path name of a file in the directory where the application resides, you should use the following method:

DimfullpathAsString

IfRight (App.Path,1) = "\" Then' if App.Path is the root directory

Fullpath=App.Path+ "File name"

Else

Fullpath=App.Path+ "\" + "File name"

EndIf

'fullpath equals the full path name of the File name

Apppath source

SEO base

When there are multiple identical files under a program, such as "e:\ ksxt" directory, there are multiple files to find the same file, then the system will find the first file in a certain order, and as the need to use the file, so, in this case, it is best to make this directory has only one file. Just like this, students who use future education software to do computer second-level examination questions will always report an error, saying that if the input exceeds the end of the file, it is looking for the wrong file. As long as the complete directory of the file is typed, it will not be wrong.
