The ListView control has a property called GridLines .It's supposed that , once this property is set to True , the control will display its grid lines among its rows and columns . However , I can't do that ! I mean I changed the property to True but still no grid lines ! Of course the View property is set to Details so the grid lines should be activated , but I can't do it ...

I have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?
I wanted to change the style, width and color of the grid lines for my X/Y scatter graph.Basically, I want to distinguish the minor grid lines and the major grid lines.
View 1 RepliesI have a usercontrol that contains a datagridview and a toolstrip. When creating a windows form that contains 2 of the mentioned usercontrol i gate for example c1 and c2 where both contains for sure the datagridview and the toolstrip hving the same control name for example G and t. in my case i want to apply the security on each form, i do this by reading the access of each control inside the windows form and if the control on the form was a user control then i dont consider it as one entity instead but as a grid alone and a toolstrip alone in order to be able to apply its security accordingly. but in ma case, if i want to disable the first grid and enable the 2nd i wont be able to do so since both grids have the same name. is there any solution for the above.

In my problem, I have a world of 200 x 200 units divided into 4 x 4 grids (Each of 50 units).
There is a line crosses some areas has the coordinates of Point A (Starting Point) of (XA = 12.43, BA = 159.48) and Point B coordinates (Ending Point) of (XB = 112.95, YB = 20.95).
The question is, how can find the length of (A to C1), (C1 to C2), (C2 to C3), (C3 to C4), (C4 to C5) and finally (C5 to B)?
In addition, how can I indicate the square in which the line is inside?
note that the method should work for all conditions (-ve and +ve line slopes) and for different A and coordinates.

View 2 RepliesI have a FlexGrid control in my Windows application that contains a row of data. The data in this row is related to even more data that won't all fit on the same row. For Example:The main data row contains Username, Last Name, First Name, Middle Name, E-mail Address, Phone Number, etcA secondary row to this might contain user permissions to certain resources, such as File Server Access, FTP Access, Remote Access, etc.Now, I can use the subtotal and outline capabilities of the VSFlexGrid to make a second row, but the column widths are still bound by those set for the main data row. Additionally, I can't put real "headers" on the supplemental data. I have to fake it by creating an additional row, setting the background color of that row to gray, putting the header strings into those fields, and then adding the next row with the actual details.
What I would like to do is create separate grids for these secondary rows and "embed" them in a blank row of the existing FlexGrid control directly under the related main data row. This would give me the ability to use a different number of columns, to format these columns independently of the "parent" FlexGrid settings, as well as put a new header row for the new grid that identifies its data.In other words, I'd like to somehow make a "child" grid that's related to a particular row of the "parent" grid (not the entire grid itself). I don't know if this is possible, and if there is another way for me to accomplish this goal, I'm all ears. However, if it IS possible, I'd love some advice on how to implement it.
I would like my program to list files from a specific directory using the listview control. For an example, listing .temp files from (C:Documents and SettingsDefault UserLocal SettingsTemp) and (C:Documents and SettingsDefault UserRecent), how would I list all the files within the listview control?

View 4 Replieshow 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.

I have a table in the database called tblChannels that I would like to draw the information from and populate the ListView control in VB, in the form of a column. I currently am unsure about how to go about doing this. Previously I have created combo boxes that draw the information from the database, but trying this method for the ListView does not work how I want it to.

View 2 RepliesI was just wandering if we could possibly export the contents of the listview control that we can select in the visual basic 2008 application. I tried to set its properties to 'true' on FullRowSelect, HoverSelection and the MultiSelect. I want to copy and paste the content of the listvew control when being highlighted. It highlights all the items inside the listview control and when you use the command ctrl+c for copy and paste it in another application like MS Excel, it only paste one item which is the first item in the row and the rest were not.
However, in the datagridview, it ables to paste all the contents inside of the control but the listview control can't. Why is it so? do i need to add codes on it or it is just the Windows OS
is not capable of doing it? How do I copy the selected items from the listview control and paste it into another application? Same as the label control which I want to highlight or select the text of the label in order for me to paste into the other application but unable to do so. These are the two controls that I'm trying to find out on how to export their contents to another windows application.
