View 6 Replieswhat i am trying to do is that i have a textbox like this which is a muticolume
[Code]...
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?

View 12 RepliesI currently have a line of text in my listview that is too long for the current width of my
listview, without increasing the width of my listview, is there a way to add a newline within the
listview line item so that it's 2 or 3 lines long so there's no need to have the user scroll to see
the text?
The code below selects all items in a listview control,fine,but I was wondering how I could code to select all but the very last line in the array.[code]

How can I drew Different colors per line in a ListView ?
If e.CommandLine.Count > 0 Then
Dim IncomingCommand As String = e.CommandLine.Item(0).ToString
If IncomingCommand.Substring(0, 2) = "-1" Then
form1.close()
End If
End If
I am trying to make the program close if the -1 string is sent with the program. See my installer allows for me to run certain programs before it actually installs, but it doesn't shut down copies of the program itself. So I have a next startup instance set to shut the program down if the -1 is received. But if the program is not running it starts up instead. This is not desired. form1.close doesn't work. e.cancel = true doesn't work, etc etc. What can I do to make the program not start during this instance.
This is going to be a lot to ask, but I'd like to convert my old GW-BASIC program to a command line program with arguments. I'd like it to operate as follows:

20 WHILE NOT EOF(1): INPUT #1, A$, B$

It even indicates if the string I'm seeking is in the middle of a line. But what I would like is for the routine to highlight the line that that string is in and ensure visible. I can do that with another routine that uses an integer, but then the whole string(line) has to be the searchString. I've tried combining the two and even calling a Private Sub but with no success:(What is the best way to do this? Also, how do you get around doing it when the searchWord in in several lines?
There's a thread that i'd read wherein you reply regarding on shortcut on populating a listview with databatable or dataset, but i forgot it. How did you populate a listview with datatable or dataset with just one line.

View 3 RepliesMy goal is to display a list of tasks with checkboxes. Checking the checkbox for a task will update the display of the task so a line-through text decoration will appear. Everythign is working great, except I can't figure out how to initially show the list of tasks with a line-through if they are completed, or normal if the task is not completed. Here's code excerpts:
<asp:Listview .../>
...
<ItemTemplate>
<asp:HiddenField ID="TaskCompleted" runat="server"
[Code]....
So this works great, when I click on a checkbox the lable gets a line-through or none based on the checkbox. Only problem is when I initially load the page, I can't figure out how to update the style of TaskLabel to show a line-through or not. I've tried some various routes, but nothing is panning out.
i am using a webclient.downloadstring to get the string lets say this is this
Item1
Item2
Item3
Item4
and i wanta send each line to its own specific item...
I want to make the text in column of ListView control to be 2 lines. So I use the codes below to test. The result is bad. The "vbcrlf" in str2 doesnot work at all. Dim str1 As String = "Job Number12345" Dim str2 As String = "Job Number" + vbCrLf + "12345" ListView1.Columns.Add(str1, 100, HorizontalAlignment.Center) ListView1.Columns.Add(str2, 100, HorizontalAlignment.Center)

I want to drag-drop single text items from ListView-A to ListView-B (both are in Details mode), but can't see how to read (and hence highlight) the index of the line in ListView-B when the mouse is hovering over it. Easy in a ListBox, but the PointToClient > IndexFromPoint features don't work with ListView controls and I just can't see another way .
View 6 Repliesthe first is validating numeric input in a textbox to make sure it's got two decimal places.

View 5 RepliesI'm a bioinformaticist, I'm trying to teach myself how to develop programs that are easy for everyday users to automate programs used in biological research. I thought VB would be great for helping people be more familiar with bioinformatics. Unfortunately, I'm brand new to VB and am stuck with my first program.
All I want to do is have a window pop up where the user then selects a file from an OpenFileDialog box, and pass the filename to a bioinformatics program names msconvert. What I've been doing keeps giving me a message that seems to says, "Unhandled exception has occurreed in your application. . . . File not found."
However, as you can see in my code (below) I have a MsgBox that shows that the correct file HAS been selected, and I can get the whole thing to run from command line.[code]....
how can i make my own program must run with command line? if the program run without command line, it show some error msgbox..
View 4 RepliesI have an Excel file I need to leave undisturbed. I can loop through it and populate a ListView with columns during form load. After that I want to repopulate the ListView, changing column headers and presenting the same data in a different order or with some columns absent. If I created my Excel application As Object when loading the form it is obviously no longer available from a new button as the button is Private. What is the convention for doing this? Does ADO.NET work with Excel? I want to keep the data source invisible (.visible = False) yet manipulate it for the ListView. I could create a text fiile from the Excel and loop through that in each button code. That seems a poor way to do it. There will be no input from the user, just reading from 22 columns displaying only 3 or 4 of them at a time in ListView.
