I'm working on a little program that uses a ListView box. I'd like to know if you can arrange the list by dragging the items within the ListView box. Example: I'd like to be able to just drag the bottom item to the top, or the middle item to the bottom, and so on. I guess I'm just wondering if I can move items around using the mouse by dragging them around within the ListView box.
View 3 RepliesI know how to drag a file to a listview, my question is regarding folders... How can I add a folder to the listview? I know a folder is not a file, but, is there a way to "recognize" it as a folder and then add any icon in its place?

The below code is not working as expected. each row has 5 items. When the user drags to right in the first row, It is giving the TargetIndex as 5. It is giving the same value for targetindex, when the user drags the item in 2nd row to left end.

View 4 RepliesI am looking for the best way to dynamically arrange the location of labels (or any control for that matter) during runtime in a Windows Forms application using VB.net or C# in VS2008.I have a control that displays messages created by users.This control has a panel docked at the top which holds the header information for each message, called pnlHeader There are 8 labels: 4 of them display static descriptions (e.g. "To", "From", "Created Date", "Completed Date")And the other 4 display the relevant data for those descriptions. (Passed in during runtime from a MS SQL 2005 DB).Static labels are named: lblCreatedDateLbl and dynamic ones: lblCreatedDate The application runs on monitors of various size and resolution, therefor I would like for all of the labels to arrange themselves with equal spacing in pnlHeader, based on the current width of the panel.
At first, I had simply created the labels in the Designer and used Anchors (half of the lables were set to (Top, Left) and the other half to (Top, Right)). This solution worked for most scenarios, but did not always provide a consistent solution, so I decided to add the controls in code instead.
I thought it would be easier to work with the labels by creating a panel for each corresponding pair. So pnlCreatedDate would hold lblCreatedDateLbl and lblCreatedDate I wrote 2 methods: 1 to define each label and add it to the relevant panel: Sub AddLabels
and another to determine the width of the panels and set the correct location: Sub SetLoc Currently, AddLabels runs in the constructor after InitializeComponent() and SetLoc is called after the data has been passed in from the database.
I've tried making minor changes and tweaks to the width and size parameters, enabling and disabling AutoSize, but nothing returns a consistent solution, instead either all the description labels are misplaced, or do not appear at all or completely whack locations come up.
Private Sub AddLabels()
'Label Created By:'
lblCreatedByLbl.Location = New Point(0, 0)

Is it possible to take an Excel spreadsheet and move some columns around? Basically I receive spreadsheets that need to be re-formatted and have the columns shifted, some also need to be deleted. I have no idea how to go about this, is it even possible? It's always the same columns so it's not like it changes from file to file. I know it probably makes more sense to just create a macro but I thought I'd see what was involved in it anyway.
View 1 RepliesI got a list of objects. Each object has a property called Z (integer).There will come a point during run-time I will want to re-arrange such objects in my list depending on their Z property. The objects with lower Z go first in the list, and the ones with higher will go last.I have thought of a couple things, like making a new List, then loop through each object in the original list as many times as the amount of objects such list has (so if it has 10 objects, I would loop 100 times), and each iteration will check the Z values. When a cycle is done (for every 10 iterations), I will remove the object with the lowest Z number in cycle and add it to the new List. And so on until the 100 iterations are done.

Issue : Is there any efficient way to arrange many independent Windows Forms in .Net? I have to display many forms at the same time in my application. It is a graphic charting application, and the number of forms depends of what the user wants, so it has to be dynamic. Is it possible to arrange it like with MDI Layout ?
Example: For example, if user chooses 12 output chart forms, I would like to have them auto-arranged 4x3 on the default screen. Ideally, User could even choose many target screens among the monitors he has.
Why not use MDI: I do NOT want MDI, since my application is multi-screen and I want to leave the opportunity to the user to put his external output chart windows scattered over different screens wherever he wants. But I would though like to have a default arrangement of output windows, without calculating manually screen and forms width/heights by dividing and stuff (Already doing this, it's a real pain). I would like to spare myself this ant-work and focus on business logic.
What I am looking for: If somebody knows an open source library or tool or cool method that could be great. By the way, I found a very useful and handy tool that could help people having the same needs I am formulating here: It is named AquaSnap, but unfortunately code is not Open Source. PS: Again, I Know how to do it "by hand" and assign monitors to forms. It is not the kind of answers I am looking for.
I am working in vb2008. The auto sort for the treeview doesn't sort the way I need. For example:

1

10

I'm using mscharts, but my question might not need to be chart related to be answered.My chart contains 5 XY data points that will be shown in a spline (line graph). The X values are from text boxes 1-5, my Y values are from textboxes 6-10. I'm adding them to my chart by code.
[Code]...
My issue is I have to enter the data in order to make my line proper. Is there a way to first arrange the points, then add them to the chart. Otherwise if I add a lesser point in the middle, it "z's" the line.
I have a line like this
18N694 P321 117461, 50374 50MIL;
XTAL_X1 P253 116711, 66524 39MIL;
HR_ICH_HUB_CLK66_R P1567 109761, 68424 39MIL;

V3_3_MGMT_PWR_RST# P3482 4711, 90024 100MIL;
From the above line I have to look the last word MIL. Then I need to arrange the line in ascending orders according to 30MIL,50MIL, 75MIL and 100MIL. Can I use IComparer? Because here I dont know how I can reach the word MIL and sort.

How can I get items in listview? I know how to get the current item if selected but I am trying to put it in a loop where I need to get my three row items there. I have 3 columns and I want to get there items and insert it in entry string.
This code is wrong
Dim a As Integer = 0
For a = 0 To ListView1.Items.Count
columname.Text = ListView1.FocusedItem.Text(a)
columntype.Text = ListView1.Items(a).SubItems(1).Text
columnscale.Text = ListView1.SelectedItems(a).SubItems(2).Text
entry = entry + columname.Text + " " + columntype.Text + "(" + columnscale.Text + ")" + vbNewLine + "" & _
""
Next
If I look at all the options for
me.ListView1.Items(index)
one of them is for Name.
So instead of coding
Me.ListView1.Items(index)
I can use
Me.ListView1.Items("Name")
But if I go into the properties of the ListView1 and look at the collection for the Items there is no place to set the Name.I can code Me.ListView1.Items(1).Name = "Name" and then I can code Me.ListView1.Items("Name")Where can you set the "Name" of the Items in a ListView?
Can someone help me about the following code? how can i get the sum total to the label.[code]
