Project PMainForm.exe raised exception class EAccessViolation with message 'Access violation at address 00000000. Read of address 00000000'.Process stopped. Use Step or Run to continue.
我单步跟踪了,出现如下提示:Project PMainForm.exe raised exception class EDBEngineError with message'Table does not exist.
File or directory does not exist.
file:F:\by\tsyhb.db
file:F:\by\tsyhb.dbf
file:F:\by\tsyhb.text
file:F:\by\tsyhb'.process stopped.Use step or Run to continue.
这提示的 意思是不是数据库文件不 存在或者打不开?我是用Database Desktop创建数据库的,打开file->open->table时,老是提示unable to open table.
