  1. In Topic: Error when compacting .accdb database in VB.NET

    Posted 9 Jan 2015

    Make a copy of your database.

    Open Access without a database

    Run compact and repair on your copy from there and see if the error gives a more meaningful description

    I've often found that the actual software produces more verbose error messages and sometimes point you to the actual reason whereas the error that vb.net returns does not.

    If, from this, you discover the reason, correct the problem and try to execute your compact command again inside vb.
  2. In Topic: Put checkbox in any listview cell

    Posted 28 Dec 2014

    A datagridview would be easy to set up to do this

    It would have a Textbox column and 4 checkbox columns

  3. In Topic: Updated dataset to access database

    Posted 28 Dec 2014

    Can you give us an example of what you tried using what andrewsw linked.

    In your code you are filling a dataset from a table in an access database, deleting the contents of the table and then merging a second dataset filled with data from a spreadsheet.

    His example skips the deletion process by just taking in the data from the spreadsheet and inserting it into the table. Which is essentially what it appears you're trying to achieve.

    This can be done using an OledbCommand and using the second dbProvider string you have in your code


    So basically:
    Create the connectionstring
    Create the connection
    create the sql statement (basically provided with only changes that reflect to your setup)
    Create the command passing it the sql and connection to use
    open the connection
    execute the command

    This should give you a table that has what it previously had plus what you pulled from the spreadsheet.
  4. In Topic: Use variable from textbox and run command line

    Posted 21 Dec 2014

    have you tried using " base" instead of "base"?

    Since base is a string you're concatenating, just add the space to the beginning of the string.

    alternatively, you would typically include a space between 2 quotes

    Textbox1.Text & " " & "base"
  5. In Topic: Generating receipt number and save to mysql database using vb.net

    Posted 19 Dec 2014

    There is nothing here that will insert a record into a database. The code you supplied only pulls the maximum id and adds 1 to it and then returns that values with your prefix.

    I would assume you would want to take this return value. Use it in a record that you are getting ready to create but you have shown no code which creates that record.

    Question: Why do you care what the maximum number is? This should be nothing more than an ID that is autogenerated against the row to keep it unique. As another person pointed out, displaying a prefix to the record on the printed/shown receipt is only cosmetic as far as the database is concerned. Externally you may have a receipt number of BSP000001 but internally 1 is your unique id and would be used to determine that you are working with the correct row.

    So in closing, until you create a statement that executes and INSERT a new row into a table, the code above will always show the same result
