View 4 RepliesI have a listview that I add items to by loading from a file, and that works fine. I then edit the items or add new ones, and on form dispose, the file is supposed to be saved containing the listview items, but when I step through this process, mylistview.items.count is said to be zero, which I know is not true because I can see the items right on my screen, I added them myself.[code]I use this same method for saving and loading to and from listboxes, and it works fine.

View 7 RepliesI'm making an app on wpf.Basically, I have a list view with 6 columns,For each item of the listview, its details are displayed are displayed in each of the columns, except the first.Basically I want the listview to automatically display a count of the items for the 1st column.[code]I have sorting and other weird stuff happening in the app, and I want to keep the first column constant. All that is needed from the column is that it counts the items.[code]I just realised this isn't vb .net so to speak.I code only on vb .net, but having trouble with that xaml bit atm. Would rather not use vb codes for solving this particular matter if possible
View 1 RepliesWhen changing selecteditems (the items themselves, not which ones are selected) in a multiselect listbox, sometimes the operation does not happen and items are deselected. Here is a simple example of what I mean, just a form with a multiselect listbox.

I need to display the selecteditems in a label I am using VB 2005 I set the selection mode to multi-extended It did work selecting only one item with the following code:
me.xresultslabel.text= me.xlisttextbox.text.selectedItem.tostring
But when I tried to display more than one item using the following code:
me.resultlabel.text= me.xlisttextbox.text.selectedItems,
I get the following string on the label:
system.windows.forms.listbox+selectedobjetcollections.
How would i get this to work on a listview to count the total in the header colums called Cost.
This is a code for DataGridView how do i get it to work in listview?.

int val = lstvRecordsCus.SelectedItems[0].SubItems[0];
The returned value is an int in a string datatype. I need the right hand side to return the value in int instead of string.
I tried Convert.ToInt32, it didn't work.
All the values that comes from SelectedItems[0].SubItems[0] is of type int.
I was testing to get the values from the ListView which works fine when double-clicking a row in the MouseDoubleClick_event, but in the SelectedIndexChange_event it crashes. I get an error that the value of "0" is not valid for the index.

I am designing an clock-in/clock-out program as a learning exercise. So far I can type the name of an employee and add them to my timeclock database in a row called "EMPNAME". The issue I'm having now is that I need each of those employees in column of EMPNAME to appear in a combobox when I hit "GET LIST". Is there a simple way to do this using a SELECT statement for the commandtext? I've tried to google but cant find exactly what im looking for.

View 4 RepliesI've a got a homework assignment that chooses one of four values in a list box, stores it in a text file. Secondly, on the display click event it should access the text file, read the line, store it in a variable and then display the totals in a text box. Works sort of fine except that it doesn't display the totals correctly. Code for both buttons is below. The variable are assigned in the mainform (Tried also in the display button and didn't change anything). The save button works fine and stores fine in the text file, it's just the reading that's the problem.
