View 6 RepliesI think we can just draw an image that resemble the grid using this article : drawing in a datagridview Currently creating a way to make the image drawn in tile mode. Each time I develop a datacentric application using VB.NET regardless of how much the data displayed in the datagrid, I always want the grid to display full row of empty data, not just blank panel. Can we achieve this using VB.NET design time property? And also, we must not trigger the display of vertical scrollbar this way..

I am making some kind of calendar where I can add tasks, so I can easily organise my tasks. For it to complete, I have 3 things I can't figure out how to do it:
1. When I launch the program, I want the items in my listbox to be sorted alphabeticly.
2. I want to save the items in the listbox, so if I close the program and reopen it the items are still saved in the listbox.
3. The items in the listbox all start with a date, fe. "13-4" for today. If that date already passed I want that item to be deleted.
Next listbox value:
1
2
3
4
5
6
7
8
9
10
11
I want to remove the first 9 lines remain in listbox:

I am writing a click event to delete an item selected from a list view which will utlimately be deleted from the csv file the information is coming from.Currently I am having streamreader read each line and then replace the selected line with a blank line.

How can I use VB to loop through the textbox, deleting Lines 1, 2, and 3, skipping the fourth, and repeat? Or, rather, record every fourth line into a new textarea?
Using this [URL] to retrieve both address and place name at the same time ("//span[@class='listingTitle']|//div[@class='address']/text()[normalize-space(.)]"), I can get a list of placenames and addresses like this in a richtextbox:
jh ryder machinery limited
convenience storage ltd 3344 rideau
rd, gloucester, on, k1g3n4
kitchen interiors 146 colonnade rd,
nepean, on, k2e7y1
The first line is bad, it doesnt have an address. Line 2 and 4 are good, they have addresses. So what I could do is:Check each line,if the following line doesnt contain "numbers + ON" then delete line. This will leave me with PlaceNames followed by addresses, which I will then split every other line into a new textbox, (so I have one textbox with placenames, and another with addresses).

how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.
i want to delete an item on a listview, this is my code
If ListView1.SelectedItems.Count > 0 AndAlso MessageBox.Show("Do you want to delete this item?", "Confirm", MessageBoxButtons.YesNo) = Windows.Forms.DialogResult.Yes Then 'make sure there is a selected item to delete
ListView1.SelectedItems(0).Remove()
End If
now my problem is i want to delete that item on the text file line
( using streamreader and streamwriter)
I've seen posts on deleting the lines from a text file that are specified as a function parameter, but I only need to delete the first and last lines from the file.
I'm still a newbie when it comes to working in files, but it seems that it should be simple to delete the first line... Just delete all text from BOF to the first CrLf character. Am I right?
As for the last line, I understand that I'll have to get a count of the lines in the text file to find it (as the file won't always be x amount of lines long).
I need to know if there is a way to remove any items from a listbox if they contain no text. Like if there are three items(Blah, ,Blah) listed in the listbox like so (remove the middle line that is empty so the listbox now contains two items(Blah, Blah) listed like so Or if there is a way to do this to a textbox that would work too. I'm working in VB 2010
