Saving Listview Contents To A Single File?
Nov 17, 2010
using the code below to save and reload the contents (text and images) of a Listview to a single file. The images are about 100x100 pixels.The problem is that if I save the images as JPG (they are already JPG when adding them to the ImageList/Listview), then after saving and reloading the data a dozen times, the images get distorted. When saving/reloading the images as PNG a dozen times, white spots starts to appear on the images. I guess this is because the images are converted over and over again when saving them.Is there a better to way save the contents of the Listview to a single file? I do not want to save the text and images seperately, because then the user has more to tamper with.
vb.net
<Serializable()> Structure TB_INFO
Public stdPic() As Byte

I want to make a button to save the contents of a textbox to a text file.
However, I want to create a popup screen so I can select where to save it and as what file name like the picture below.
Is there an easy way of doing this or do I need to create another form to do this.

I've got 1 form that has the user enter 7 fields of data.When they click my "Save" button those values are stored in a .DAT file.On that first form there is a button that brings up a second form with a listview control.I have all the headers set up but can't figure out how to populate the listview control with the contents of the .DAT file.A friend of mine told me I may need a Do while loop but this is my first time doing this and I am so lost. I don't even know where that loop would go and whether or not I need extra variable for it.

I have a subroutine which saves data from a listview to a txt file which is named "listview.txt". I want the file name to change each time I run the program, by putting the date and the match number into the file name instead of the word listview. I have a global variable called Todayda for the date and one called MatchNum for the match number. Is it possible to have variables in a file name? If so, how can I do it?
Attached is the code, which works fine otherwise.
Sub PermMatchRec()
Dim outputstream As New IO.StreamWriter("c:listview.txt", True)
Dim newstr(10) As String
Dim st As Short
Dim myint As Integer

I have one form which calculates something and displays it into the listview but then when Print button is clicked another form will appear which has a differently layout but same information. And on that print form there is another listview, how I would load the contents from the first listview to the printout lsitview which is on a different form.

I got a string array & I need to show the contents of it to a single label. It acts like a clock. The thing is I tried with everything I could but I failed. This is the code I've been trying. Its in vb.net. And theres a thread running to slow down the loop so I can display the contents in a label for 2 seconds.
Dim j As Integer
For j = 0 To readText.Length
label.text=readText(j)
Thread.Sleep(2000)

make a diary style application where a password must be typed in then when that is typed in it is possible to view and edit the text. I have it all working but the only problem is that I don't know how to save the text box's contents. I have read a few threads and haven't found an appropriate answer. The problem is that since it's supposed to be a diary I would like to save the text so that it may not be read, preferably not by making another file but by storing it in the program?
Here's the code I have for it so far:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Password As String
Password = TextBox1.Text
[code]....
Textbox1 is where the password is entered, Textbox2 is where the actual text for the diary would go, Button1 processes the typed in password, Button2 hides the text and clears password box, Button3 does nothing and has the text "Save" and I would like to use this button to save. Is there also an automatic way of saving?

I've got a textbox using a custom auto complete source, which gathers info from what the user has previously typed. Problem is, I can't figure out how to have that source saved when the application closes and loaded when the application opens.

I have been working on a project which is used by a company's sale team, to combine all the wanted input data in one place allowing the sales team to show customers, where switching to them could save them money.
Basically what i want is a program which can save single records, which can hold data added in other text boxes, or indeed take the data from the list view boxes which is the intended output. I want to be able to save that data, then be able to Open it up again at a later date, and even modify it.
enabled me to save the three ways to identify a single record, the index number, company name and the date it was added. However I now need a way to save the data entered in my other forms to these single records.

I am trying to print the contents of a listview to paper from a toolbar button. In the code below I can get the printer to function and print but cannot get the listview contents to print. I found an old post by Martyr discussing printing listview contents in debugger that was helpful but have not been able to figure out what part of the code to modify for the print sub to recognize the listview contents in the handler. This is what I have so far:
Private Sub PrintToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintToolStripButton.Click
Dim prn As New Printing.PrintDocument
[Code].....
The printer portion of the code that runs on the strip button works without any problems. If I use that button click code above and add something to the PrintHandler Sub like this:
args.Graphics.DrawString("Hello World With A Printer", New Font("Arial", 20, FontStyle.Bold), Brushes.Black, 150, 125)
It prints the "Hello World String" with no problem. The issue is I am not sure what or how to refer to the contents of the listview in the Print Handler Sub or if this is even the correct way to attempt this.

I'd like to go through all the items of a ListView control in order to ... well execute some code. I suppose I have to use the "For i=1 to ..." statement , but I am not familiar at all with this control. As I said , I'd like to check all of the items (the elements in the first column) and for each of them that has "Yes" on the third column , I would like to run the rest of the code .

ok Here is a little code I've been working on, now what I want is for the same icon/image to be shown for each item in my listview box. I want it to work kinda like when you have a group of images in a windows explorer folder and you press 'tiles' they each have the same icon indicating that they are an image. I am trying to do it the same way I produced my thumbnails so to speak but it doesn't work, it still just only shows the file name. I know there is probably something little but i can't figure out what is wrong,ideas?

However I need to interact with a program designed in vb from perl (yes I MUST do it this way....)
The control I need to get text from has a class TL80.C1List32.20 I believe this is a listview. I can get a handle to the control just fine.
I have access to the SendMessage function via a wrapper with this prototype:
SendMessage( $hwnd, $msg, $wParam, $lParam );
(A $ denotes a variable in perl)
The listview also has 2 child windows of class: TL80.C1List32.20_SC
which I believe are scrollbars.
I need to retrieve (but not set) the items in this listview via the wrapped SendMessage function.
I can provide any other information you'd like from Winspy++ or can probably dig it up on my own if you let me know what you need.

I have a listview with three columns: Employee ID, Firstname and Lastname. When the user selects a row in the listview, I would like to have the Firstname and Lastname for the selection chosen to be output to a label. I know how to select a single item from the listview and output it as text. How do I output two items from the listview to a single label? Firstname listview item is: EmployeeListViewSelectedItem(0).SubItems(1) and Lastname is SubItem(2)

I can't claim credit for this code but I think it's cool. It will show the entire contents of an item in a tooltip even when the columns are truncating it. Drop a tooltip and listview container on your form with the default name.
