Proper Update And Delete Code For SQL Express In 2008 Express Edition?

Oct 3, 2011

I'm just using the default SQL Server Express in my vb 2008 express edition as my database server for my database operation. When I tried to update the records on my table I got a runtime error which indicates the error on this line 'myCommand.ExecuteNonQuery()'and it highlights a yellow background on it. The runtime error says "SqlException was unhandled: An expression of non-boolean type specified in a context where a condition is expected, near 'Number'. ".

Imports System.Data.SqlClient
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

Unhandled SqlException In VB 2010 Express Thta Does Not Occur In VB 2008 Express?

Oct 16, 2010

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error  "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."

I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).

Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.

INSERT Or Update In SQL Server 2008 R2 Express In VB 2010 Express

I am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

COM Object Handling Differences Between 2008 Express And VB 2008?

Jul 15, 2009

I recently created a very simple project in VB express 2008 to interface with a COM object from an external vendor. I then downloaded the VS2008 90 day trial and found that the identical code in a VS2008 project results in a COMException error "Object is out of scope".  Is anyone aware of any differences in how the two packages handle COM object interfaces as I have run out of ideas. Both projects have identical code and all the references are the same. The CreateObject() method correctly creates the object, but any attempt to access methods inside the COM object result in that error. I can even open the VB 2008 Express project inside VS and it still generates the same error.

Here is the code - the vendor dll in question is from Siebel v8.0.0, you'll notice that I have commented out most of the code that comes after the error. Creating a watch in the debugger on the siebApp variable sees it correctly created as {System.__ComObject}type SiebelHTMLApplication. I first tried this by creating the Property Service for variable siebSvcs, but after I started experiencing the COMExceptions, I reverted to using the most basic method inside the COM object I was creating.

VS 2008 Connect VB 2008 Express To A Database File

Jan 12, 2012

I am using VB 2008 express and SQL Server 2008 express on a test basis and I used to connect VB express to a SQL database (created in SQL Server 2008 Express management studio) file and it work perfectly until my hard drive packed up and I had to get a new one, so I had to reinstall both of these again and copied my old databases from a backup I had. Now when I try to connect to the database file it cannot connect. Network related error or the instance name is incorrect. When I look at the advanced options in the connect dialog it shows my instance as .SQLExpress and my correct instance name is .SQL2008Express. I clicked OK on the connect dialog and manually changed my connection string to the correct instance and that worked but whenever I run the application in debug mode it give me the same error as above.

Use .next (random Numbers) To Randomly Select Something From A List Of Numbers But It Can't Repeat The Number?

Aug 16, 2009

So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:

dim num as integer
dim r as new random
num =,5)
if num = 1 then
elseif num = 2 then

That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.

Example:This is in a label.

Dim number as Integer
number = 0

Then in the button do

Label.number = 0

How would I do something like that? I want to use that a lot as I did in a different language.

Box - Conversion Error - User Enters 6 Numbers In 6 Different Text Boxes - Displays The Larger Of Those 6 Numbers

Oct 4, 2011

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.

Here is my code Example


This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.


Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.


And do this with variable number 2, 3, 4, 5.

I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

Program To Randomly Select Numbers For A Bingo Caller - Prevent Reversed Numbers Being Selected

Mar 6, 2011

I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.

One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.

So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.

So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.

Sum Numbers In Listbox - Add All Numbers Together And Display The Result In A Label

Jan 10, 2010

I'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.

This is the code that I have that i think should work.

Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
lblTotal = FormatCurrency(sum)

When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.

This is my revised code:

Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
lbl_Total.Text = sum

Just some suttle changes made the difference
