I am very new to Visual Basic, and I need to add items from my database to the ListView control. I have a table in the database called tblChannels that I would like to draw the information from and populate the ListView control in VB, in the form of a column. I currently am unsure about how to go about doing this. Previously I have created combo boxes that draw the information from the database, but trying this method for the ListView does not work how I want it to.

View 4 RepliesVS2010 Professional crashes when I select Choose Items from the toolbox context menu (right click). All has been working well since it was installed in March but just suddenly started with this behaviour. I had an issue with one of my apps which caused a total VS freeze at about the same time this issue started but the app is now working correctly.It had stopped me from using VS2010 and I reverted to vs2008 but that has developed a bug which prevents me from creating / accessing any data connections. A bit stuck now.I have removed and installed VS2010. Initial reinstall attempts failed due to unverified msi file (??). However, I have now successfully installed VS2010 back on the machine. Crash problem still remains.

how to update fields in an Access database through VB. What I'm supposed to do subtract the quantity of the daily orders from the inventory quantity. My textbook is a little bit vague at this point, because the only way it describes updating the DB is manually through the BindingSourceNavigator. I don't want to enter it manually, I want it to subtract the quantity from the orders table.

View 3 RepliesI am trying to pass some information from a VB form to my MySQL database. i have named all the textbox's the same as the field in the database and checked all my database fields and textbox names which are all correct. When i try to enter information into a form I sometimes get an error at the .executeNonQuery section of the code.
To test, I outputted the SQLStatement string to a textbox ( which pulled through all the fields from the textboxes correctly) then manually inputted the completed SQL query into the database and it worked. But when I try to do this in one go it seems to fail if there is too much text ( if i enter 'a' into each field it works). Are they limits to the size of the SQL query that can be passed from VB?? all the MySql database fields are set to text with no size limits.

View 2 RepliesI'm learning how to add items from a list box to a combo box. I'm trying to follow what's going on in the function loop and comparing a boolean and selected index. I can see that it's comparing the item chosen to each item already in the combo box to make sure that it's not already there. If function finds that it's not in the list it sends back that it is true that the item is not in the list.
It then continues to the statement that adds item to the list. The code for the double click event is working fine and items are getting added to combo box. However, the code for the add button isn't functional. I'm not seeing why it doesn't work? I coded out the original code, and replaced with something I thought might work but it still isn't functional. [Code]

I have some code that adds items to a List(of Object).

Dim BeaconStoryList as New List(Of My.StoryType)
Dim BeaconStory as New My.StoryType

But as soon as the code assigned "Chicken" to BeaconStory.Title, then BeaconStoryList(0).Title would also change to "Chicken".
With my second version of the code this did not happen.
It's as though it was placing pointers into the elements of the array rather than values. If that is the case, however, then why does my second version of the code work - I'm still passing in the same thing - aren't I?
