View 6 RepliesOkay so I have decided to upgrade my game from vb5 to vb2008 express edition. When I opened it I was told it needed to be converted so I said ok. However, there are some things in the language syntax that have changed.Obviously. Well here is one of them:

Setting controls to objects allowed me to cut down on typing but it seems you are not allowed to reference things without the "full path". I understand that you now have to set the full path of the object but doesn't setting something to an object already do that? Do I have to just delete the object references on the top and instead of using objCmbGraveU2 I now need to replace it with frmMain.cmbGraveU2?

I've recently decided to switch from VB6 to VB2008 and am looking for some advice for a certain type of book I seek.Already I've aquired several VB2008 books, but the type of reference book I'm seeking I can't find.For VB6 I have a book called "The visual guide to visual basic". It's a very very very very old book but its gold, platinum and diamonds in one.This book basically takes ALL controls, commands, etc, and in alphabetical order as a sort of encyclopedia, explains its purposes, possibilities, properties together with many examples.
If I was uncertain about a control or command I could simply look it up in this book and almost always find what I was looking for.My question, does anybody know of an equivalent for VB2008?

I am new to SQLSever, Visual Studio and Visual Basic. I have read through Microsoft Visual Basic 2008 by Michael Halvorson and Microsoft Visual Studio 2008 by Lars Powers and Mike Snell. These books mention the ability to use SQLServer as the DB but I am not clear on the process. I am not knew to programming an have had training in OO programming but have never done any OO programing professionally. So, you can assume I am new to OO programing.
I have created an SQL DB using the Server Explorer in VS, and created a Windows form with Labels, TextBoxes, and ComboBoxes for the application's user to add the demographic information about a new employee. I created a new query with the Query builder that is in the Employee table of the DB which contains all the field for the record for inserting. I have a few questions to understand the process for inserting into the DB.
The DB fields are defined as numeric(6, 0), nurmeric(5, 2), and char(30) for some examples.
The maxlength on the form windows are in sync with the maxlength of the DB for the various fields.
1. What is the process to update the DB with the fields from the form?
2. Do I need to declare and set the results from the form first? If so, how do I call the function (query) that I created in the Employee table.
3. The emp_num I would like to be a dynamically incrementing number starting from 1000. How do I make this a dynamic? The emp_num is also the key on the Employee table.
4. I have a decimal field on the Employee table to hold emp_rate (pay rate). Does the user enter the decimal on the Form or is this resolved by SQL to take the 7 numbers and insert the decimal beause of the table's field definition?
My pc is a Vista SP1 + VS2008 I try to import a csv file into an existing access database with the following code but I have the message that the database is only in read access and I can't update it with the csv file.I tested the code on an other pc with XP and VS2005 and it works.

I'm writing some VB2008 code to control four 7-seg LEDs I bought from Velleman. They came with some example code in VB 5.0, and with instructions telling me to input 5 bytes at a time in the format Chr$() & Chr$() & etc. for the rest of the 5 bytes. When I try to do this using VB2008, it rejects the $ sign, so I've tried it using the Chr() format, which VB2008 allows. However, it doesn't work. Is Chr() the new version of Chr$() or are they different entities? In sending data to the LEDs, I'm using LiveComPort.WriteLine() as my command. (My serial port is called LiveComPort) I also tried it with LiveComPort.Write() asthe command. I know that my serial port and the LEDs are working, because they respond to the demo program provided by Velleman.
View 7 RepliesI have inherited support for a program written in VB2008
The problem I have is as follows:
Users have a low screen resolution (company policy) and so can't see the bottom of a particular form.
The bottom of the form has buttons that allow them to navigate between its' four pages so they need to be able to see them. This being the case I need to add a scrollbar to the form.
If I try to drag and drop a vscrollbar from the toolbox it just sits there at runtime (you can slide the button on the toolbar up and down but nothing happens regarding scrolling the page.
All the reading I have done seems to point to forms being given scrollbars in accordance to the AutoScroll, AutoScrollMargin and AutoscrollMinSize properties of the Form itself.
By setting these properties I can get scrollbars to appear in the IDE but they are not there at runtime.
I think I'm probably missing something really obvious here but, so far, have been unable to work out what it is.
