I am using the code from hereevelopment/vbnet/code/370426 to sort my listview items. But I want something more 'dynamic': when I click on a header column, I want that it changes the sorting based on the column that has been clicked. here is my code:

how we can sort a listview on column wise in a simple way?
View 2 RepliesIn 2007 I created a program that reads weather data into a listview. When a user clicks on the column header it fires off the column click event handler which calls the Sort Wrapper function. The Sort wrapper will re-order items either in ascending or descending order.
I have never been able to get negative integers to sort properly. I have created a stripped down listview program with a few numbers in the grid for testing. (see attached program zip file).When you run the program, click on the column header that says "Val" and you will see right away that the numbers do not sort correctly.
i used the sorting method at msdn but it isnt nice. it sorts in string format like 1,11,12,2,21,23,3,31,32 etc. is there any other sorting method.

How to do that? I think this involves API Functions calling like "SendMessageA" etc
But I never did programming with Windows API Functions.

View 4 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'm dealing with image files so I need to have the image with the item.
I have an image list which is called img and the open file dialog is ofd1.

first is Username
second is Password
I want the information under those columns to be save as a text file in this style:
username1 : password1
dowpkf : wateverpass
and so on .so basically the items in list view should be saved in this template username..
im trying to do is find out the command to compare itemview items with textbox, so i dont end up with 2 of the same customers when i add a new entry, if anyone could give me some advice i would be greatful just a hobby, bold line is my problem in script, need to try and replace.

View 1 Repliesi have 1 button, 1 listbox and 1 textbox.this is my code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ListBox1.Items.Clear()
Dim finish As Integer = TextBox1.Text
[code]....
if i set the sorted property of listbox1 to true that code will add 0 before the inputted number so that the sorted property in listbox1 will be usefull in sorting integers.
for example i have 1,15,30,36
it will make 001,015,030,036
thats what i think am not sure because i cant edit the code so that it will work in my program.
I need to sort the items in a visual basic listbox numerically, that is, I have a collection of numbers I would like to be sorted increasingly.
I tried to simply use the listbox's Sorted property, but found that it treated the numbers as if they were strings, that is, it would look at the first digit, then the second, etc. to determine the order. That meant that 13 would show before 5, for example.
I thought of dumping all the numbers into an array, soring the array, and then pushing them back to the listbox, but, honestly, I don't know how to go about the sorting. I figured the array would be useless, since the listbox already acts as a pseudo array.
I have a Windows form with a menu strip (the built-in one, nothing custom).I want to add a new list of items to one of the current menu items programmatically (no problem, done that).The new list of items I am adding is unsorted, but I want them to appear on the menu in alphabetical order.
