View 2 RepliesI download a file into access. One field contains one to many numbers always separated by a colon and a space: I have no control over the download. TheNumbers have a 1 to many relationship to a customer. Each number must then be verified against two separate reference files, and if the numbers match the description related to the number will be displayed.I'm just learning visual basic. I've made the changes manually (yuk-this took forever); I've tried various string/conversion commands; I've taken the data and placed it into excel and tried to manipulate it, without success.In this case is always numeric. In another field, similar problem, it's a combination of text and numbers.
Example: Cust# TheNumbers
99 1234; 12345678; 123123; etc...
88 87654321, 345654, 98989898. etc..
The numbers can vary in length and quantity. For each customer each number must be loaded into one field.
Example outcome:
Cust# TheNumber
99 1234
99 12345678

I'm using VB2005 and I got a message error in a runtime: Abstract does not belong to table tblBooks. I don't think that the problem is its datatype. I'm currently using MEMO datatype because I need to load it more than the capacity of string. Is it possible to use this code in order to accomplish it? txtAbstractInfo.Text = MyTable.Tables(0).Rows(Counter)("Abstract").ToString
txtAbstractInfo is the name of my textbox and my field's name is Abstract.
I have a table in an access db that is viewed via a datagrid view in a vb.net front end.The primary keys for this table are PKJobNo & PKProcessNo I need to allow the user to change the order of the processeses which means changing the PKProcessNo field value and then re-ordering the grid by PKProcessNo In the example below
proc 3 becomes proc 2
proc 4 becomes proc 3
and
proc 2 becomes proc 4
I can't just change for instance process 2 to 4 as these are unique values.
PKJobNo ProcessID PKProcessNo Note

I am having a problem with something seemingly basic and typical. However, I have tried and searched for many hours, I could not find a solution. I am using Visual Basic in Visual Studio 2008. I tried to bind a textbox to a numeric field in an MS Access table. When I enter an number to the textbox, sometimes it would be converted to another number when I tab out of the textbox. For example, if I type '123456.78', it would be automatically changed to '123456.781', '123456789' would be changed to '123456792'. The wrong numbers are stored in the database too. For smaller number, it seems to be OK. For example, '1234.56' is O
