vb.net - Empty row doing insert -


I have tried to enter a record with a new table and show the message below:

"Input String was not in a correct format."

This is my code: 

  dim max_like string = "maximum of the table (reference_number) Select "slow outputs" as the new datativus dim dsi is in the form of new data. Dataset obj_ Populate_dataset_Access_accdb_test (ds_, max_) Integer = Convert as Egg Ref. ToInt32 (ds_.Tables (0). Roov (0) .emem (0) .ostring) Ref = ref <1
< P> The table columns are intact with zero.

If the table is empty then the MAX taps will be returned. This means that your Dataraova will have DBNull.Value, whose toasting method gives the string. The empty, which can not be clearly converted into integers, test for the first tap, using Datarou's own isole method.

Of course, you can always do as many thousands of developers around the world and make the database sequential id for you.

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
