View 1 RepliesI am trying to develop a recipe manager that allows a user to create a shopping list. I've already determined that I want to use a list view for this job. I want to be able to group the items in the shopping list by the appropriate grocery aisle (i.e. Dairy, Bread, Canned Goods, etc.) I'm not sure how to assign the items to the appropriate group as the user selects each item.
I haven't started actually building the application yet as i'm still in the development stage, but i have been testing the list view out to figure out how it works. i've figured out how to add items. i just don't know how to specify the group that each item should belong to.

View 4 RepliesI started working on a product list with an array of products, these products are in a list view. You click the item and it is added to another list view and removed from the one it is curently in. I had it suggested to me and it sounded neater. I had no problems tinkering with codes and getting it opperating properly. But, What I am having trouble with is putting a cost to the product.
The idea is that the user would select products from the list and then they will be totalled together which is why it is important to be able to get the cost in there but not actually visable.Athiest advised me of a method used in combo boxes, because i was originally working with combo boxes. So I tried using that for my needs in a list view. Turns out to be a little more awkward than I thought. I get an error while trieing to add the item to my list box because I havent "declared" it.

I am creating a program that allows a user to view a list of foods in a combo box, add that food unto a list box, and adds all of the calories of that food together. When the user highlights their select food, the program automatically shows the amount of calories for that particular food in a text box. The program is getting the food and calorie information from an access database. I managed to get all of the food calories to add up properly, however, I ran into a problem. Sometimes, well, most of the time, when I select certain foods from the combo box, the program automatically reselects another random food, usually a food that begins with either an A, B, or C. Also, the other random food that the program chooses usually has the same amount of calories as the food I originally wanted to choose. I have over 6,000 items in the database. I don't understand why this is happening. This is what my code looks like for the button that adds each food to the list box:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
Foods_Selected.Items.Add(ComboBox1.Text)
Static i As Single
[CODE]...
And this is what my code looks like for the button that adds all of the foods together:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim x As Single
Dim TotalCalories As Single
[CODE]...
I have no idea what to try. It's like the program just skips over random foods, even though all of the information for them is in the database.
I've got a TCP Listener running on a separate thread. I want to have it log the incoming and outgoing messages in a list on the form instead of in message boxes. I've been reading about multiple threads, and I know there's something extra I need to do because form controls are not thread safe.
Unfortunately I've tried several tutorials on delegates and invoking but it still doesn't seem to insert the log items to the list. I even spent $60 on this Mastering Visual Basic 2010 book to "Build Rich Client and Web Applications with Visual Basic", but there isn't a single chapter on how to handle multiple threads.
I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

View 5 RepliesI have been working on an app that was basically a vb6 app but had to be changed and I did it all using VB 2008. works well, great. One of the problems that I had was to work on different groupboxes or frames. Since they are layered on top of each other, working on one frame would mess up the others. Eventually it all went okay. but now if i want to add another item in the menu and hence add another groupbox (or frame) in the same app - it would definitely be a nightmare.

I get some very generik trouble need to implement List View with Image in SubItem. All can be very fine ....But I need to use Virtual Mode. Whatever I search I haven't still found working solution's.

View 2 RepliesI have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

View 1 RepliesI have a listview (details) with owner draw set to true (so i could make rows alternate in color, looks cooler) which basically contains items and subitems whose texts reflect status info that updates constantly
the problem is, sometimes (if the task runs quickly) the status changes really quickly, and as a result, listview items "flicker" for a millisecond no error, no real problem, its just really annoying and makes the program look less professional.
Is there a way to make the listview not flicker? Or maybe there is a way to make it so that the listview doesn't process too many drawsubitem calls during the same time interval? or maybe there is some customized list view out there that does the trick better?
NOTE: i tried with owner draw set to false. it flickers less, but still flickers. same problem :S
Also NOTE: i am not making cross-thread calls. i have 50 items in the listview and 4 colums, mainly the last 2 subitems change.
I got my code to read a txt file and import it to a list view. (that is on the form2)so on my form i I want to grab the value of listview1 line 1 in form2 so I tried

But I get an error then I added .tostring in the end and with luck I got something like listviewritem {Jhon}but I only want jhon. Dont want to add trim or delete?
