This is a simplified version of a class that I have in my project. Since the Bonus is figured the exact same way in each function I want to remove the obvious code duplication that appears here and make the three different functions into one. However I am not sure how to provide the argument that this new function would require.
For instance I am currently just passing the argument like this from code
lblVolumeBonus.Content = TestClass.VolumeBonusAmountStore(bonus).
I think I have to basically turn this logic around and call it with something like
lblVolumeBonus.Content = TestClass.VolumeBonusAmountStore(BonusTrackerBO.StoreBonus)
but I am not sure of the correct syntax or whether I am on the right track at all.
Public Class TestClass
Public Shared Function StoreBonus(ByVal bonus As BonusTrackerBO.StoreBonus) As Double
[Code]....
Edit: It may not make a difference but I should have made clear that there are other factors in the equation (I was just trying to keep it simple). So is the answer the same when there are other callbacks to the bonus like bonus.MaximumAmount, bonus.MinimumAmount? There are 5 callbacks to the bonus object and the amounts are different depending on whether it is a Store, District or Company asking.
Am developing a resume data retrieving software where data is stored in one parent table and 4 child tables as such:
Resume_table ----> Parent table
holds ----> Res_ID, Emp_ID, Lang_ID, Task_ID & some other static data
Employee_Table--->which is referenced directly to Resume_Table.Emp_ID similarly ol other 3 tables are referenced to the main parent table Storing and retrieving data is all working fine as long as I am retrieving 1 record for each child tables But some times there might be couple of languages and only single records for other child tables.In dat case as the four child tables are ol in separate subreports whch are called onto the main report whch prints as cv gives redundancy in data i.e by giving duplication of ol records twice which were single records during entry, which i think follows the language table if it consist of 2 records.am using a join query to call these records onto crystal report...

1.Are exceptions used to indicate error rather than returning status or error codes?
2.Are all classes and public methods commented with .NET style comments? Note that <summary> comments should discuss the "what" of public methods. Discussion of "how" should be in <remarks> blocks or in-line with the code in question?
3.Are method arguments validated and rejected with an exception if they are invalid?
4.Are Debug.Asserts used to verify assumptions about the functioning of the code? Comments like, "j will be positive" should be rewritten as Asserts.
5.Do classes that should not be instantiated have a private constructor?
6.Are classes declared as value types only infrequently used as method parameters, returned from methods or stored in Collections?
7.Are classes, methods and events that are specific to an assembly marked as internal?
8.Are singletons that may be accessed by multiple threads instantiated correctly?
9.Are methods that must be overriden by derived classes marked as abstract?
10.Are classes that should not be overriden marked as sealed?
11.Is "as" used for possibly incorrect downcasts?
12.Do classes override ToString instead of defining a Dump method for outputting the object's state?

My datagridview is bound to a data table. I want to filter the datagridview without affecting data table. I know one way is to use bindingsource, but binding source will use column names in its filter. But I want to enable users to enter any string in a textbox to filter. So I pass datagridview by reference to a function PassFilter which removes unwanted rows in datagridview. I can see that it does execute rows removal in datagridview.

My MS-Access database contains 30 "table" files with identical formats (e.g. Composer, Arranger,Lyricist, etc.) and I use a common VB.NET form and DataGridView for displaying and editing any one of the 30 tables. When a user makes a menu choice, the menu program puts the file name and its first field into two global variables and then shows a form that contains an unbound DataGridView. This other form then loads a dataset from the appropriate database table and programatically binds the DataGridView to the DataSet. (I clear the dataset before filling it.)
All goes well and three DataGridView columns are displayed for the first time. However on subsequent operations, the DataGridView retains the columns that were previously generated along with their column headings (but no data) and I get six DataGridView columns. On the third operation I get nine DataGridView columns.
I have unsuccessfully tried to obtain a count of the number of DataGridView columns so that I can remove them from the DataGridView but it always gives me a column count of zero.How can I accomplish the simple task of removing all columns from the DataGridView?

View 3 RepliesI've gone through various thread, posts, classes and walkthroughs on sites but seem to be coming up short either in my understanding or what is/should be going on.I have a very simple data entry tabcontrol (think like microsoft excel but textboxes, labels and the odd combobox rather than a grid). When I click one tab it creates a new tab and names it according the sequence (no problems so far). Here is the crotch kicker (for me at least). I need the first tabpage layout on all additional tabpage so that data can be entered in each separately and stored with constant "processing" (adding and subtracting ).What would be the best approach to doing such a tabpage duplication?
Currently a User control library inheriting from tabpage seems like a good idea but with the 40 or so controls on it is this actually going to function like the first tabpage (as in the one i have now not the one I'd have if i used the user control instead).Do I take the raft of code the designer creates automatically for the tabpage and its controls and simply add them to the click event? Would this create duplication problems with name or would it be ok as they would be tabpage1.lblName and tabpage2.lblName?
