Using database

[gilseorin]

Hi!
My project is almost done.
But,due to clumsy at using database and subroutine function,
having difficulty in completeing my project.
If anyone help, I would be happy very very much.
Attached file below.
Thank you in advance.

With this code, I could have only 1block inserted, then I erase it and with defalut layer "0" setting, purge all, and another block can be inserted with error message.
How could I have inserted all blocks at once with the command "blf" with no error?
I could not do anything against this.
Any help, I would appreciate it.
Dear, All ! Help me,plz.
Thanks in advance.

I think your problem is with a bug in the API that means the Has method you are using to determine if the block definition exists is returning an erased object. I use the following function to return valid SymbolTableRecords. See the attached text for how I deal with it.

Dear Nathan!
Thanks for help, but I don't know where to add your code for my one. I am novice and this is my first program with .net.
Sorry, but could you help me more?
Thanks.

I have attached your code with modifications commented but I have not tested it.

I should also credit that my original example was derived from a C# example posted by Tony Tanzillo.
