I have a fixed percentage 0.3% I need to multiply this by a number of months which varies 1 to 12
Having done this I need to add the percentage to a pre-determined number
so as an example
£300 + (0.3 * 10)
I can get the 3% (0.3 * 10)
But when I add this to the existing number (£300) it equals £303 not £309 which is what it should equal.
Can anyone advise the way of adding a percentage as appose to just another number? This also need to allow for -percentages i.e. -3%
The equation I am using is below and I appreciate there is nothing to set decTotalPercentage as an actual percentage but that's because I am stumped...
decTotalPercentage = decPercentage * intMonths
decFinalPercentage = decMoney + decTotalPercentage
I have a dataset that is being populated from a text file.
OrderNumber,Name,Model,Cost
123,john doe,product1,20.99
123,john doe,product2,10.75
There can be multiple of the same order number. In the dataset, I want to have a column "line number" and I want to put in it the value of the linenumber (in this case 1 and 2) per order. In sql , I was able to accomplish this by inserting rownumber() and grouping by order number. Can this be done in .net?

View 1 RepliesI have an Access table which has an auto-number primary key. When I add a new record to it I want to be able to get the value of this field.
The relevant code I have is:
dsNewRow.Item("FullName") = NewStudentFields(0)
dsNewRow.Item("FirstName") = NewStudentFields(1)
dsNewRow.Item("LastName") = NewStudentFields(2)

I want to be able to access the value of the primary key immediately after the Update (if that's possible without having to search the dataset for the new record - cumbersome!) or, even better, just before the Update, if that's possible.
How do you add an arbitrary number of controls to a form at run time? With indexed controls I could define the 'seed' control at design time and reference 'clones' of the 'seed' control at run time via the index. Now I must declare each additional instance of the control at run time then set each individual property that differs from the default for that control for each instance. Then I must add the newly declared control to the appropriate container controls collection. I'd like to do this in a loop but how can I get away from using a fixed control name in the declaration:
Dim controlname As New Control
I can't use a string that I can manipulate the contents of for controlname because it sees it as a double declaration. I can't use an array such as Control(index) for controlname. Dim Control(maxindex) As New Control doesn't work. Dim Control(maxindex) As Control works but any assignment based on this such as Control(indexvalue).Name = "ControlName" fails. It didn't address the issue of handling the declaration of new controls in a loop with some kind of variable name for the control.
I'm trying to write a function which obtains the sequence_number by counting the records in a table that fit a particular criteria and if the result is 0 or nothing sets a variable to 1 but if the result is 1 for instance, the variable will be set to 1 + 1.
This is the code i'm using but i'm not getting the correct result when results are actually returned. For instance, if the result of count is 1, i want "seq" to equal 1 and total (which represents the sequence # assigned to the next record which is entered with the same plan and date) would therefore be 2 which is the result of seq + 1 (i.e. 1 + 1)
