sir,
    I am doing the Project VB with MsAccess. i am having error message "object variable or with block variable not set" When executing an query with the connection Object of Created Exe. But the same error is not coming in the VB Project. Please send me the solution as early as possible

You need to provide enough details for someone to identify the point of the problem.
What is the actual statement that throws the error?
What have you done up to that point to set up the context in which the error-throwing statement is to run?
(And so on. Try to put yourself in the position of those you are asking for help, then provide everything that you think you would need to give an answer.)
