Call A CLR User Defined Function Within The Assembly
Feb 14, 2012The 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
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes
[Code]....
Why can I open the connection if I call the function directly, but it fails if the function is called from another function?

Define An Array Inside Of The Sub Call Parentheses?
Mar 22, 2011Is there a way to define an array inside of the sub call parentheses?
Private Sub sub_name(byval sString, arrString)
sub_name("Some Text", array.{"","",""})
What I've been doing is passing a string and using a split on it to break it into an array in the Sub/Function, but I was wondering if there was a way to make the array inside the parentheses. I've looked through Google, but I'm guessing I'm not asking the right questions or it's not possible.

Create An Equivalent To #define From C++ As A Shortcut To A Ridiculously Long DLL Call?
Oct 19, 2010I'm trying to create an equivalent to #define from C++ as a shortcut to a ridiculously long DLL call.

In C++ I could put "#define _GET = TheThingBase.TheSubThing.FurtherSub.TheThingIActuallyNeed(string).I am not seeing this functionality or even a close resemblance anywhere.

Generating User Instances In SQLServer Is Disabled
Apr 18, 2007I am a beginning programmer and am tying to add a database to my visual basic 2005 express program. I have a nice working window but now a database needs to be attached. Following the add items and selecting the sqldatabase icon (and change the name) I get the following message: "Generating user instances in SQLServer is disabled. Use sp-configure 'user instances enabled' to generate user instances". I am trying for 2 days to find out what to do.
Aparently, all the solutions on the internet are for wizards but not for apprentences. I hope to become a computer wizzard but are far from it now. I scanned my computer for the file sp-configure but it does not exist. I tried sp_configure as a DOS command, checked all VB menu options to find etc. On the internet the language is out of my league and jumps too quickly.

View 10 Replies[2008] Make Sure That Each Call To The Function Is Much More Random?

Dim objRandom as New Random

intRoll = objRandom.Next(1,7)
Return intRoll
Everything works as expected as far as generating a random number (1 - 6) is concerned, except for one problem. If I have a series of calls to the function one after another, the numbers come up the same. Is there a way to make sure that each call to the function is much more random?

Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One
Apr 1, 2010I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. 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
Here's my call:

Function Call For Multiple Textboxes Using Visual Basic Studio 2008
Feb 17, 2010I am working to make a function that will update the back color of a text box based on multiple variables values. I can write the code to do the calculation, but I am not sure how to make the function realize which text box to update (as I will have about 30 different boxes). Below is the code that I have for each box so far, but I will have quite a few more, and would rather use a function to reduce the amount of code, and also make it cleaner as well.
If sngPreviousPrimaryPropertyTotal >= sngPrimaryPropertyTotalCost Then
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightGreen
Else
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightRed
End If
[Code] .....
Or is there a way that I can tell the function that it's updating the text box that call the function in the first place? Say if txtBox1 has updated text and calls the function, then the function 'knows' to update txtBox1, but will update txtBox2 when it's called by txtBox2.
Allows The User To Define Text In A Rich Textbox?
Sep 14, 2010I have an application that allows the user to define text in a rich textbox. I would like to give the user the ability to define text for one or more languages. I don't think this will be a problem using the rich textbox as it allows for unicode characters and DBCS (please let me know if this is incorrect). My question is, I display this text throughout the app in other controls as well, such as a listbox, label, etc. by acquiring the RTF's Text property (plain text). Are there problems with other controls displaying unicode/DBCS characters? I realize that I may have to toggle the font of the control in question depending on the language (I will allow the user to specify a default font per language).

The possible actions would be "no action", "run timer", and "stop timer."I could do this with an integer (e.g. 0=no action, 1=run timer, 2=stop timer), but I'd rather create a data type so that the options are more explanatory than a simple integer. Like so....
