VS 2008 Update/change Data In Listbox?

Jan 16, 2012

I cannot figure out how to change the data in a listbox. I'm being driven completely mad by vb.net, finding it very very complicated.

Ok I have two list boxes on a form that contain correlated data i.e. the first item in the first list box corresponds to the first item in the second list box.

Under the two list boxes I have two text boxes for data entry.

For Example :
LstTagDatabaseLoop LstTagDatabaseSource
TxtTagDatabaseLoop TxtTagDatabaseSource

I want to Add Update and Remove items from the list. If the user selects an item, I want the selected item in the other list to change to correspond. I also want the two text boxes to be udpated with the currently selected item.

[Code].....

however this invoked the selectedindexChanged sub umpteen dozen times and while in the end it did actually update the data, its obviously not the right way.

I found ListViews which perhaps is more appropriate but I couldn't get my head around it at all so returned to trying to use these listboxes. Is there a different object I should be using.

I'm finding vb.net to be too complicated for a hack programmer like myself...

VS 2010 - Update Data Source When Database Field Definition Change

Nov 11, 2010

I'm using a MS Access 2007 database. I modified the field definition of one of the fields in a table, it a text field and I change the maximum length from 40 to 150. I have a data source in my app that contains this table and many others. I refreshed the data source but the change didn't take affect. I went through configure option but the change still didn't take affect. It gives me this error,
The value violates the MaxLength limit of this column.
If I add/delete a database field the data source is updated when I go through the configure process. I finally just deleted the table from my data source and then added it back.

Formatting Excel - If I Try Using Style.numberformat With The Date And Time Formats, They Don't Change And Are Entered As If Didn't Change The Format?

Mar 11, 2011

I am throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.

Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11

Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM

For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation

BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.

Gridview Doesn't Update Insert/update Commands

Jul 21, 2010

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?

How To Change Update Location Of Program

Apr 27, 2010

An update to my program has been downloaded to a particular folder. The code recognizes that the file is there
(i.e. "If IO.File.Exists(My.Application.Info.DirectoryPath & "UpdatesPQCM.exe) Then),
Sets the update location to that file and initiates the click-once update subroutine. Problem, I don't know how this update feature can be modified this way in run-time. I would set the update location using the solution properties but this program may exist anywhere on the hard drive, or even on a thumb drive (as per its design).

It errors on the da.Update line and by the way if it helps, the text fields are a product of datarowview. that is when you select an item on the listbox the details of that appears on the text fields. and my goal is i could edit those text fields and save them.

DataGridViewComboBoxColumn Change To Automatically Update DataGridView?

Jan 24, 2010

I have a standard DataGridView. One of the columns is a DataGridViewComboBoxColumn. When I select one of the ComboBox items, I want to trap the change and add additional columns based on the item selected in the ComboBox. I've tried using CellValueChanged for the DataGridView column, and a bunch of other events, but none of them is fired when the DataGridViewComboBox value is changed. What event can I trap to make this happen? Right now as I said, I am using CellValueChanged, but of course the event doesn't fire until I click on another cell...
