I created a listbox that displays files from a certain directory, and want to know how to actually get information on that file, rather than just the name its self that is displayed in the listbox.
This is what I have:
Dim files() As String = IO.Directory.GetFiles("C:Users" & (System.Environment.UserName) & "Desktop", "*.txt", IO.SearchOption.AllDirectories)
Label9.Text = ListBox1.SelectedItem

problem that i am facing is i want to add array of object as a single item in listbox. in vb6 i was using this Label1.Caption = Label1.Caption & Mid$ (strInput, intI, 1) & " " List1.AddItem (Label1.Caption) i was using label. caption to store object but not work in vs2008 because label.text only take text and left other values
View 18 RepliesI have 2 listboxes on my form.Listbox 1 - populated with "available" field namesListbox 2 - populated with "selected" field names.There cannot be the same field name in both listboxes - it's either one of the other.The logic I was going to apply was to populate Listbox 1 with every field name ... and then as I populated Listbox with the field names which the user has already selected, remove the corresponding item from Listbox 1.

View 3 RepliesI use a simple master-detail form using Visual basic 2005 express edition and ms sql server 2005 express edition, as well.
The master table is dept (deptno int, dname nvarchar(50)) .
The deail table is emp (empno int, deptno int, ename nvarchar(50)).
The primary key for the dept table is deptno and for the emp table is empno.
There is also a foreign key (deptno on emp table).
I created a new project, connected to a db (called test.mdf) and created a data source consisting the two of the above reffered tables.
I dragged and dropped these tables on the form and i noticed the following:
1)When the form opens... the system queries the database and displays the data on each block on the form.
2)I insert and/or update a record on the master table (dept) and everything goes well...
3)I try to insert and/or update a record on the detail table (emp) and nothing is changed on the detail table - without any error.
4)When i try to insert and/or update a record on the detail table (emp) which violates the primary key constraint or foreign key the system complaints...(as expected).
I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code:
Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1
AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID
Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.

View 13 RepliesI've been trying to add to a listbox item from a different thread (thread 2) than the thread in which the form/listbox was created (thread 1).
When I check ListBoxItem.InvokeRequired from within thread 2 it is always false when ApartmentState.STA is set. When set to MTA I get an error. Thread 2 is a unique thread with different ID from thread 1.
What is frustrating is that at one point it was working fine, and then I changed some of the structure of the project and it has now stopped working (and I don't know which change caused this! It was a while ago).

i have a list box which is populated with the sub folders from a user selected folder, so the listbox item count varies from 2 item to 1000 items etc.The list box code i use to do this is:
Dim lb1s As String = Form1.Folder.SelectedPath
Dim di As New IO.DirectoryInfo(lb1s)
Dim mydirInfoArray As IO.DirectoryInfo() = di.GetDirectories
Im trying to make a feature were on a button click the app will create 1 folder for every item on the listbox (named after the list box item)So if theres 3 items on the list box for example:
001
002
band 3
[code]....
And when the user presses the button, the app will create 3 dupe folders (Only the folders, not the contents) in a user selected directory using the same names, ive been tinkering for a little while but cant seem to figure out a way to implement this.
this is going to be hard to explain but ill try. Question 1. Ok i have a list box with a few items, What i want for this example is to click a button and it will start on the first item and do: MsgBox ("this is item blah blah blah") then after that it will go to the next item and do the same and then the next and so on untill all have been done. The "blah blah" should be the item so if item was to say "hello" then the msgbox would say "this item is hello" I know this would be a lot of msgboxes to close, like if 50 items then thats 50 msgboxes to close, this is just for the example.
Question 2. Ok this is where ive tryed to learn but find it really hard (multithreading) Im wanting all to be multithreaded so all work at the same time, ive tryed a few times but the only way i see it is having a **** load of subs, like if i want it to use 10 threads then ill have to add the same code 10 times or somet, im not sure.
i have attempted all this and failed big time as my way was to get the first item and use that then remove it from the listbox BUT... with it being quite fast the 2nd 1 and 3rd 1 used the same item befor it was removed and to be honest i dont really want them removed. so my attempts took like 2-3 days that was a waste of time really. I Know this is a lot to ask but im in real need of it and these 2 things have driven me half mad.
For Each item As Object In ListBox1.Items
If item.ToString.Contains("http://" Or "www." Or ".com" Or ".net" Or ".org" Or ".biz") Then

what im trying to do is loop threw all listbox items until the listbox item contains say "panda" and stop and give me the index of the item that contains "panda"so i would end up with panda`s selected index
