Below is my formula for a field in my report. All fields are of value type 'Number'. When I try to save the formula it gives me error "The result of selection formula must be a boolean." Why is this? Sometimes it does not catch it as an error, but when I actually run the rwport with real data, it shows the error again. Sigh.

I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

I am using Crystal Report 10.5.3700.0. I have created a report which is using stored procedure. Now from vb.net code (in VS2005) I set the selection formula like: proSaleByPerson;1.PersonsId=1
But when the report load its giving following error "Query Engine Error 'ADO Error Code:0x'", Failed to open a rowset. Keep in mind that all other reports are working fine only that reports creat problem which are using stored procedure, when setting the selection formula.

In my asp.net application I am running a script to generate a new project my code at the top level looks like this:
Dim ok As Boolean = True
ok = createFolderStructure()
If ok Then ok = createMDB()
[Code]....
I create a boolean and each function returns a boolean result, the next function in this chain will only run if the previous one was successful. I do this because an asp.net application will continue to run through the page life cycle unless there is an unhandled exception and I don't want my whole application to be screwed up if something in the chain goes wrong (there is a lot of copying and deleting of files etc.. in this example).

In the Customer or Contacts tbl?

So in keeping with this convention I am trying to name a method in my program with this prefix but I am running Specifically I have a class called Day. It is a simple class with a few data members and one method that returns a boolean value of true or false. The name of the boolean variable is isSpecialDay. This class has a method called isSpecialDay which takes the date of the day, applies some criteria to the date and then sets the variable isSpecialDay to true or false. My problem is that the boolean variable is named isSpecialDay and so it the method. What should I do?

I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?
Found this:
Sub SurroundWithAppendTag()
DTE.ActiveDocument.Selection.Text = ".Append(""" + DTE.ActiveDocument.Selection.Text + """)"
End Sub
But I can't seem to figure out how to loop through each line of text in the selection.
