Receive Upper Bound And Lower Bound Of A Range
Sep 20, 2010Is there anyone who can tell me the code for the below? Receive a lower bound and an upper bound of a range. Also receive a number of random numbers to generate. You must validate
1) the numbers are integers
2) the lower bound is less than or equal to the upper bound
3) the number to generate is positive (i.e., > 0).
Generate this many numbers in the specified range and keep track of how many of each are generated in an array of counters. Once all the numbers have been generated, display in a List Box the number, the raw count data, and the percentage of how many times the number was generated displayed with two decimal places of precision.

View 1 RepliesBound Datagridview Not Bound?
Jul 9, 2010There is something strange going on with my datagridview.
I've a data adapter that fills the underlying data table from a database. Then I assign this datatable as datasource to the datagridview Then I add a row to the datagridview and immediately I need to update the table in my database (as soon as user leaves the newly created row).
At this moment I have more rows (+2, not +1) in my datagridview than in the underlying datatable (the new row doesn't exists yet in it so the data adapter .Update method doesn't write anything to the database).
When DataGridView's .RowLeave event fires the undelying datatable is not yet updated. I've a question - is this behavior normal?

View 39 RepliesDataGridViewComboBoxColumn Cell Value Is Not Valid
Jul 11, 2010I get the DataGridViewComboBoxColumn cell value is not valid only when the record in the ComboBox table does not exist. I have done quite a bit of searching on this and I can't find this particular situation mentioned.
I have a datagridview with a comboboxcolumn on it, both generated entirely in oledbdataadapter code. The datagridview is created, then the combobox is created, then the combobox is added to the datagridview, then the datasource of the datagridview is set. It works just fine. Except if there is no matching record in the combobox table I get the "DataGridViewComboBoxColumn cell value is not valid" error popup. I could trap the error but it seems to me a beter way would be to prevent it from happening. Is there some property I can set or something I could do to compensate for the situation where there is no match in the combobox?
