VS 2010 Can't Populate Listview2 A Second Time
Aug 5, 2011
Trying to build a file compare utility to compare two files and visually show the differences in the rows. I have a form with two panels and a listview in each one and a vertical scrollbar in between that will control both listviews.First listview1 inside panel1 will load during form load depending on what is selected on my mainform grid. 2nd Listview2 inside panel2 will load from btn1, this only works once.The compare is done with btn2 and it works okay also.The problem I have is after I have both files loaded up in the form, and I do the compare, everythign works fine but I can't figure out why I can't seem to re-use btn1 to open up another file.It seems to go through during debugging but the listview2 will be blank. Only does this after it was first used.[code]

Basically what I want is when a person clicks on an Item that ends in "Mp3" in Listview1 to then Create that same File on Listview2 So far It will create the File, not show its name. and it gives the directory, but not all the way.
Heres the Code for Moving the file to listview2.
If ListView1.FocusedItem.Name.EndsWith(".mp3") Then
ListView2.Items.Add(ListView1.FocusedItem.Name.ToString, 4)
'Add SubItem Information.
Dim li As New ListViewItem
li.ImageIndex = 4
[Code] .....
I wont get anything to pop out on Listview2, even if I click anything on listview1. I have to group (left click and hold, and go over multiple items.) And if I am lucky I will get some stuff on Listview2. I got 1 item to move to listview2 but it has no name (it does not appear). Now if we move the scroll bar to the right, we will see another error, (next picture). The Directory Does not end with the Music's Name.mp3. And It does not even end in the same directory as the textbox on the bottom right corner?

I am building a program where for part of it the user can enter a parameter which will then query a database and populate a DataTable with the results if the number of results is greater than 1 it will call a "lookup" form to popuate a DataGridView with the DataTable, from this the user can select a row and the result is passed back to the main form or if the result is not there the "lookup" can be closed.
This works fine the first time the parameter is used to query and opens the "lookup" form and populates the DGV, but if the user returns the the main program after using the lookup form and enters a new parameter and the lookup form opens again the DataGridView is not created and populated. But i am 99% sure the DateTable is being populated as if the row count is 1 it will automatically return the single value and this is happening even after the lookup form has been used.
So it is just when the Lookup form is being used a second time the DataGridView is not being popuated or the DataTable is not being passed.

I have an ArgumentException was unhandled message: Cannot add or insert the item '1' in more than one place. You must first remove it from its current location or close it. Parameter name item. Note: Have 2 listboxes 4 textboxes double click listbox2 and it fills in the four texboxes (now it needs to put it back into listbox2 in the same place it came from but crashes. I marked the area and underlined where the error message was coming up. So double click a selection in listview2 (fills 4 textboxes) then double click textbox2 (should return text data back to listview2 in same spot) but crashes. See code below.

I'm writing a report scheduler that is somewhat of a clone to the backupexec scheduler and the layout can be seen in post #10 here: [URL]..It works great and saves/edits/deletes records just fine, but now i need to compare those records one at a time in a windows service that i'm writing in order to trigger automated report creation and emailing - i already have the report and i already have the code for the emailing, i'm just looking for the most efficient way to loop through the table (that i've pulled in to a dataset) and compare its records with the current date and time - if true, the event fires.
[Code]...
1stSun, 2ndSun etc are bit fields, time is a datetime, and the remainder are varchar. My service checks the database every thirty seconds.The english version of what i'm trying to do is "Connect to the database, grab the entire table (it will always only have 5-6 entries max, so i felt 30 second sweeps was okay), and If today is the 1st Sunday of the month, and it is currently 11:00:00 a.m. (could be any day or time, this is just an example) - loop through the dataset to identify if any records match the time field or greater - if they do, fire the report

I'd like to have a backgroundworker process data that will eventually populate a gridview in my windows form. I need to use a backgroundworker because the process takes a little while, normally causing the program to slow/freeze until it's opening and streaming connections.. So, I'm using a background worker to perform these methods.How can I take the data from the background worker (on a separate thread than the UI) and use it to populate controls in the UI?

The below code is a sample code that is supposed to display the months in a combobox.
Dim months() As String = _
{"Select a month...",
"January", "February", "March"}
[code]....
But what am I supposed to do with this code? I have created and named the combobox "cboExpirationMonth", but where do I put this code? I tried to put it as a click event of the combobox, but that doesn't work. I created a button and tried to put the code in the button's click event, but that still doesn't populate the combobox.

In this windows forms app, I have a form with six comboboxes. Two are parents, one with a single child and the other with three children. All of these work beautifully except for one of the children. The code for each one is identical, and I've verified the query against the database a dozen times. I even have another of the children that is in the very same block of code. One works beautifully, the other one refuses to populate any data. Below is the code for the one that doesn't work. I would tell you on what line the error occurs, but it doesn't throw any errors. Try catches show nothing, and I have VS 2010 set to throw all errors, but I get nothing, just an empty combo box where there should be a list of names.

I have a procedure that populates a ListView, but it does a lot of work and it takes too much time to display all it's items (about 100-200 items). I want to use a thread to display the items as it's extracting data (real-time).

on the form I use one combobox with Data Bound items, Data source, Display member & Value member. Besides this combobox I have textbox with multiline turned ON. My code should write values from specific table in Textbox when I sellect ID on the combobox. Actually this code works but not in a way I want Me.TextBox2.Text = ComboBox2.SelectedValue
I would like to populate texbox from other columns as well. For my app I need one texbox in which I can see five lines of data, Company name, Address line1 & Address line2 & Address line3 & Address line4 . It's important to get data from different columns and each column in a new line.

i have a Userform that I created in MS Word that automates almost half my job. I'm just looking to re-create this form in VB.Net so that I can keep up with the trends.What I did previously was load a listbox based on the contents of a data table in another word document. I've searched for other methods of creating a datasource in VB 2010 Express but I'm unsure how to load the contents of a dataset or datatable as opposed to a table from MS Word. Ideally, I'd like to abandon using Word tables and create a dataset in VB and load a listbox based on that. I do not have a copy of MS Access and I'm unfamiliar with MySql, which I'm guessing would are the easiest methods of loading a dataset. I also thought that maybe if I could create a seperate form (let's just call it form1) specifically for entering new data and saving the form as data is added, then linking the datasource from that form to a second form (form2) that has the listbox that will populate with the contents from the data in form1.

I have a very simple program which simply populates a listbox with a list of files stored in a directory.
Try
lvScripts.View = View.Details
lvScripts.Items.Clear()
lvScripts.Columns.Clear()
[Code]...
However, I'd like to embed these files into the application itself and open them from there rather than from looking at the directory.To this end I've added each of the files as a resource but I don't know how to populate the list view with a list of the text files in the my.resources rather than a list of the text files in the directory.

Part 1 of what i want to do is on the Load Event of my form i want to look at an excel worksheet and populate a data table with the data found in the first two columns of the worksheet.
Essentially column 1 is Descriptions and column 2 is pricing
Part 2 of what i need to do is that when a user selects a description from the combo box it populates a text box with the appropriate pricing.
After doing some reading into this all i have seen is some threads on how to use Jet4.0 to link and grab the data but it is my understanding that Jet doesnt work with 64 bit OS.
Nonetheless I need to figure out a way to accomplish my end goal and make it as universal a solution as possible (ie. i do not want it to only run on 64 bit or 32 bit machines)

I want to display (DataGridView's) selected row contents (each cell value on appropriate text box) on text boxes on the form. This should be fairly simple task for experienced i am sure.So far i haven't been able to find a single working solution to accomplish that as most of the articles are written for VB / VB 2005/ VB 2008 and not VB 2010.
Here is what i have already tried. (I tried putting an image but i can't due to my privileges over flow) TextBox1.Text =DoctorsDataGridView.CurrentRow.Cells(0).Value.ToString It strangely works for first 4 selected rows and populate text boxes but fails for the rest of the DataGridView.

I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have

It is really only the last part of the If.. Then statement that I need help with. I was thinking that a loop would accomplish what I am trying but I am still pretty new to VB and do not know the correct code.
