Add correct identification of the relative file path of the Access database to the vtemplate

Vtemplate was recently used in the project. Its datareadertag TAG provides the ability to directly access the database. Its internal parsing provides encapsulation of database connection operations. However, when accessing access, the relative path cannot be used. Therefore, locate the database operation file and find the getdatasource () method in the datareadertag class.

Add

String STR, str2, str3;
STR = str2 = str3 = Setting. connectionstring;
If (setting. providername = "system. Data. oledb ")
{
System. Web. UI. Page page = new system. Web. UI. Page ();
Str2 = Str. substring (Str. indexof ("app_data "));
STR = page. server. mappath (str2 );
Str3 = str3.replace (str2, STR );
Dbconnection. connectionstring = str3;
}
Else
{
Dbconnection. connectionstring = Setting. connectionstring;
}

In this way, you can use the relative path in the configuration file for normal access.
