About Stephen Jackson Expertise I can help with questions regarding VB.NET syntax and object references, with data interfaces and with the design and creation of robust, data aware object classes. I can also be very helpful with creating distributable applications and provide tricks and tips on .msi creation. I also have extensive experience in designing SQL Server Databases and interfacing them with VB.NET. I try to avoid web specific questions, as that is an area of expertise all its own.
Experience
Experience in the Area: I have been a programmer in Visual Basic since version 1.0 and have worked with VB.NET (which is infinitely more powerful than previous versions) since its initial release and SQL Server, both as a corporate IT professional and professional consultant. I first wrote Basic in 1976 on a TRS 80 and have worked in Visual Basic 1.0 and every subsequent release of Microsoft Visual Basic. I worked for over 7 years as a Senior Level Consultant in the area and currently hold a Project Manager position in IT.
Education and Credentials: MBA in Econometrics, 1983, University of Memphis.
BBA in Financial Management, 1982, Fogelman College of Business and Economics, University of Memphis. Microsoft Certified Professional
Areas of Special Expertise:
My specialty is the design of Object Oriented Solutions with robust, data aware object classes. I generally avoid the classic ‘Three Tier’ model as I find it redundant and cumbersome to maintain. I also specialize in the creation of ‘User Friendly’ User Interfaces which help lessen the need for user training and help prevent user error. I work best with Windows Forms based applications, and while I do work in C# as well, I prefer to limit my questions here to Windows Forms based applications created in Visual Basic.NET and SQL Server. I wil also address questions relating to the distribution and installation of Windows Forms based applications created in VB.NET.
Expert: Stephen Jackson Date: 3/26/2008 Subject: vb.net - adding/averaging numbers in listboxes
Question I know there are a lot of resources out there but I just figured there has to be some one here that can help...
My user chooses a number between 1 and 10.
He then gets to choose that amount of random numbers
example - user chooses 5, he/she is prompted by an input box to enter 5 random numbers 1 at a time.
the 5 numbers are stored in a listbox.
How can I average the numbers the user has chosen?
I am a beginner and you can probably tell. I'm not sure how to convert them and if I need a loop or not?
Answer Tim,
Luckily, VB.NET makes this easy!
Have your users separate their values with a delimiter (we will say a comma here). Create a string variable and assign it the value of the text property of the text box. Then create a string array ... and use the 'Split' method of the String Class ... that puts your values into an array .. then just loop through them!
Dim strEntered as String
Dim strStringArray as String()
strEntered = txtYourTextBox.Text
strStringArray = strEntered.Split(",")
