I'm a new user of VB.Net. I do have doubt on accessing a user defined Function or Sub. In some place of program, I do see the term "Call" when using the Function/Sub. In some other place without "Call". But both works perfectly. May I know the difference between the two.

How can I access (read, write, create, delete) user-defined fields for single contacts in Outlook directly via the Exchange Web Service? I need to create/name a field and set a value (it should be viewable in the Outlook contact > "All Fields")I've found some code to set extended properties - it worked, so I could set and also read some values. >> but its not listed in "All Fields" of an contact.I'm using Exchange 2007 and Outlook 2007 - but it should also work with other Versions (Exchange 2003, 2007 and Outlook 2003)
View 1 RepliesThe main function receives data, uses additional functions to calculates the result and gives it back. But at one point, the function needs data from the SQL Server. I wrote a second UDF, made it visible and deployed it to the SQL Server. I see now two functions under > programmability > functions > scalar value functions:
1. The main function (IsCalcDay) and
2. The function with the data access (IsHoliday)
If I call directly the second function from VST in the debug mode, it works fine, bur if I call it via the main function, the code stops if the connection will be opened. The error is "Data access in this context is not permitted. The context is a function or method that is not marked with DataAccessKind.Read SystemDataAccessKind.Read or a callback to retrieve data from the FillRow method of a table-valued function or a UDT validation method." (translatet from German, probably slightly differnt in English)
VST (2010 prof) and the SQL Server (2008 R2) are running in my virtual W7 maschine.
Here is the code of the second function:

Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes

Why can I open the connection if I call the function directly, but it fails if the function is called from another function?

Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

View 3 RepliesWell I had a thread going that branched out to this topic, so rather completely veering off the main topic there, I felt creating a new thread was adequate.So as the title says, I'm trying to create a user-defined type. It's not a simple type at that but a user here had showed me a way to fix all my problems. That was to create a type BigDecimal. Which my initial thought was to utilize the BigInteger type. Being that the Integer Part, and Fractional parts would be split off into two variables, both BigIntegers. Which would be combined at the end as a "decimal". However I have many many questions see that this is my first attempt at truly creating a type of my own. So as of right now I'm basically swinging in the dark here.

I have a database of 7 items that I want the user to be able to choose the order in which each is listed for use further along in programming. I'm thinking of using combboxes bound to the database. I found out that each combobox will have to have its own dataset otherwise they will all show whatever the current one that has focus changes to. Is there an easier way to be able to do this or is having 7 datasets bound to the comboboxes the best way? For this purpose I don't need all the contents listed in a DGV, only need the component name for now if this helps. Database programming is new to me and I'm a hobbyist programmer from VB6 days making the transition.

These are all components that I had worked on to get to this point of combining into 1 solution. Now what I have run into is I can not the actual functions in the class libraries. I can get to the class level, but that is it. ere is a sample line of code I need to get working. Once I get this one line, the rest will be obvious: Temperature is on the main form. get for options is "Equals, GetHashCode, GetType", etc... Before this I had bult, compiled, and referenced these classes separately, and it worked fine. I know this is going to be an easy answer, I'm just not seeing it for some reason.
