Integrating SQL Query Into Excel?
May 29, 2009I have a SQL query that I want to integrate into a VBA subroutine in Excel. I have had some success using the Macro Recorder to call up the SQL query (throuh Microsoft Query) in the past. However, the SQL code that I have for this query is significantly larger than previous attempts.When I record this one through the Macro Recorder is trips up because there are too many line breaks integrated into the recorded code. To get around this I have tried to manually update previous (successful) queries with the larger SQL code that I want to use, but without success.I was hoping that someone out there has some experience in integrating the standard SQL query code (SELECT xxxx, yyyy, zzzz, *nnnn FROM aaaa, bbbb, cccc, *nnnn WHERE 1111, 2222, 3333, *nnnn) into VBA.

Integrating Java Class To Be Used In Application
Apr 13, 2012I have been asked to create a project in vb.net which needs to integrate a java class created by Apple (Autoingestion.class) to pull sales records and so on.I found out a couple of questions here on stackoverflow but none of the answers given worked for me when trying to integrate this java class in my .net application.For example this question seemed to be what I really needed but when trying to compile this java class (I decompiled it first using Java Decompiler), it generally throws some errors.All I need is to use this class in my application to invoke a method.Does anyone know how to pull this out without much ninja-ing?

View 18 Replies.net - Integrating ASP.NET Repeater Control Into Current Page?
Feb 7, 2011So I currently have a aspx page that shows details for any single staff member, and the page is setup with mostly ASP labels. I have a subroutine called "getstaffdata" that populates the page on load (via subroutine).
I would like to convert this to a page that shows details on one staff member, or many staff members, one after another. So I thought of using the repeater control, but I'm not sure how to convert the page over. The staff userids are passed via query string, but I'm just confused on how to do the datasource for the repeater control.

View 2 RepliesVS 2010 Structure Classes So That The User Interfaces Though A Single Class While The Supporting Classes Are Hidden From Their View?
Jun 13, 2012How can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
interface.Economic.MyMethod
interface.Currency.MyMethod
etc
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.

View 1 RepliesIntegrating ASP.NET C# Website As Subsite To A VB Website?
Jan 25, 2011I have a ASP.NET 2.0 website created in C# that acts as a completely independent site and I am looking to integrate this into an existing ASP.NET 2.0 website created in VB.NET. Unfortunately I just don't know much about the server management side of ASP.NET yet so too much I'm unaware of when it comes to IIS configuration etc. Does anyone have any advice as to how I can go about integrating this? Basically I want to host it in a subdirectory from root so when you hit example.com/myindependantsite/ it will pull up my C# site.
One possible solution I came across mentioned just dropping the project folder into the root directory and setting up that directory as an application virtual directory in IIS? A few other random questions were small things like would my application relative links (~/for-example.aspx) stay relative to my root subdirectory if it's made into an application virtual directory? Just trying to get this running on their site but like I said it's completely independent so want to preserve my websites environment.

Best Pratice In Inheritance - Three Classes Employee, Manager And Salesman. Manager And Salesman Classes Inherits Employee Class
Jul 27, 2010I have three classes Employee, Manager and Salesman. Manager and Salesman classes inherits Employee class.
Employee :
Public MustInherit Class Employee
' Field data.
Protected empName As String
Protected empID As Integer
Protected currPay As Single
[CODE]...
Manager :
Public Class Manager
Inherits Employee
[CODE]...
Salesman :
Public Class Salesman
Inherits Employee
[CODE]...
Now I have created a object of salesman and manager using the following code:
Dim objSalesMan as Employee=new Salesman("xyz",1,2000,5000)
Dim objManager as Employee=new Manager("abx",2,5000,"production")
Is this a good programming pratice or should I use:
Dim objSalesMan as new Salesman("xyz",1,2000,5000)
Dim objManager as new Manager("abx",2,5000,"production")
.net - Events In Classes?
Jun 17, 2010I find that I write a lot of code within my classes to keep properties in sync with each other. I've read about Events in Classes, but have not been able to wrap my head around how to make them work for what I'm looking for.For example, in this one I always want to keep myColor up to date with any change whatsoever in any or all of the Red, Green or Blue properties.
Class myColors
Private Property Red As Byte
Private Property Green As Byte
[code]....
If one or more of those changes, I want myColor to be updated. Easy enough as above, but is there a way to work with events that would automatically do this so I don't have to put myColor = Color.FromArgb(Red, Green, Blue) in every sub routine?

Can Sub Routines Be Placed Into Classes For Later Use
Feb 6, 2011I have a slew of sub routines that I need to use in my software because each website that I will be accessing don't all use the same methods.....go here...click that...go here...click that...etc etc
So I've divided them into sub routines and call them when I need them but the coding is getting so long that it's becoming confusing to keep up with each sub.
Is it possible to place the sub routines into an independent file like a class and then call them from the file when I need them so I can free up some space to code?
Classes And Objects?
Aug 29, 2010The 1st part of the code required me to write a class definition for a class(Worker). The class should include Private variables and Property procedures for a worker object's name and salary.
The salary may contain a decimal place. The class should also contain two constructors:a default and a parameterized.
The second part for the code indicates that I need add a method named GetNewSalary to the Worker class.The method should calculate a Worker objects new salary, which is based on a raise percentage provided by the application using the object.
Before calculating the new salary, the method should verify that the raise percentage is greater than or equal to zero. If the raise percentage is less than zero the method should assign the number zero as the new salary
There are three text boxes which allows the user to enter the employees name current salary and raise percentage....the calculate button will display the new salary in the new salary label box...so far here is what I have for the worker class.
The Class for the code had to be written from scratch. Can you please look over the class code and see if I need to chang anything....that will allow the program to run.[code...]
