View 3 RepliesIn my Windows Form I have a ComboBox that is filled by a Stored Procedure with a list of names. I have the Combobox set for AutoComplete to "Suggest" and From "ListItems". When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?

A couple of questions about check list boxes:
How to check/decheck all the item in the list How do you copy or delete all checked items in the list
Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.
EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.
Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck

i am using this code to uzip a file: [code] i am trying to figure out how to get the name of the file that was extracted so i can use it in my program. Can I do that using .FastZip?
View 3 RepliesI have the following code which works fine;
For Each myFile As String In IO.Directory.GetFiles(Label1.Text, "*.zip")
Dim fi As New System.IO.FileInfo(myFile)
sFilename = fi.Name
Col_Prac_no = sFilename.Substring(1, sFilename.IndexOf("_") - 1)
For example: I have filename as:
I00018_20120329042035_111
The col_prac_no = 00018
Now, I want to update the for statement to have another value extracted from the filename.
The first letter of the filename. In the example:
I00018_20120329042035_111
The first letter of the filename in above example is I.
So if we have:
S00018_20120329042035_192
the value will be - S.
i wanted to ask how to make picturebox1 ,to which functions are already assigned, perform the same function as picturebox2 ,to which no functions are assigned.For example:I have already made picturebox1 and have assigned it alot of function like when play button is pressed then picturebox1.visible = true and when we press pause button picturebox1.visible = false. So now i decided to make a theme and have to remove the picturebox1 and want to allow the picturebox2 to havefunction of picturebox1.But when i disable the theme the function of picturebox1 should go back to picturebox1.

I have been on MSDN about this and searched but it's not quite telling me what I'm after. I've extracted a list of file names from an Excel spreadsheet and want to check whether they all exist in a directory which a user can select in a text box. It feels like I'm nearly there with it but currently my listbox is displaying everything, I want it to just show the files that are missing. I'm a beginner so I'm not exactly sure if I'm even telling it to compare the two things properly, I've tried a couple of ways of checking if a file exists but neither seem to work.[code]

Now normally LINQ would give a nice clean answer here, but as I am using .NET 2.0 I can't use that.If there a nicer way to do this or am I going to have to do a for each loop and break out on finding a false?

There is a boolean property on this object called Processed.I need to check that all objects in the list are processed.So in LINQ I'd do:if (from o in list where o.processed = false select o).count = 0 then....

I have a listbox, textbox, and a button. every time I push the button, an item from the listbox is put into the textbox. when the button is pushed again, it grabs the next item in order and puts it into the textbox. so on and so on until it gets to the last item. once I get to the last item it keeps repeating the last item over and over again. SO what I was wondering is how do I get a messagebox or some sort of checker to tell me when it has moved the last item from my listbox to the textbox?? PS textbox2.text=0 and every time the button is pushed another number is added to the value of textbox2.text. so basically if I could figure out how to grab the value of lines at any given time in listbox I could call a msgbox up!! here is the code I am currently using[code]...
View 3 RepliesI have this issue right now. I have a listview with checkbox. Now what I want to achieve is get all the id (hidden column) of all check items and pass it to arraylist so that I can pass it to SQL like this:
dim intProductID as new arraylist
For i = 0 To lv_list_products.Items.Count - 1
If lv_list_products.Items(i).Checked = True Then
[Code].....
"DELETE * from t_products WHERE f_product_id in(" & intProductID & ")" The reason I do this is to have only one time open of database connection, One of the member suggested it is not good to open and close database specially if it is within the loop. One more issue is the command within the array I need to separate all id with commas so I will not have error on SQL.
ok in vb6 i would use this to check all items in a listview.

Now Here's my confusion. And i spotted at least one other person on here who was asking the same thing about this.But got no real clear answer that i could see. as a test to compare i tried his suggestion and loaded the same listview up in both a vb6 app and a vb.net app..The list i used was quit large so the comparison would be very through..my list was in the 80,000 lines range tho..yeah talk about overkill The vb6 app checked/unchecked the items within a matter of milliseconds..the vb.net took an extremely long time tho..well not extreme but was very noticeably slower about doing the loops.
