I desided to follow the basic instructions cearfully. I have managed to find my way through the database programming using the odbc class.And I was successfully able to populate records from the database to listviews, treeviews, comboboxs and all sort of controls.Now I am working on phase 2 of my project whitch is writing back to database.... but unfortanilty I did not find a good illustration of how to do that using odbc data adapters.I am trying to send data from textboxs an listviews..
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 have an outer listview and inside its itemtemplate an inner listview. Each has its own SQLDataSource. A Id field from the outerlistview works as a select parameter for the second listview.
When stepping through with the debugger it works perfectly, unfortunately the rendered page only contains data from the outer listview. It appears the databinding of the outer listview fires and renders the page (including the inner listview) before the codebehind can provide a where parameter to the second listview. The aspx page is below.
I am currently making an application manager program that allows users to create application shortcuts which are represented as ListViewItems. One feature that my testers keep suggesting is way to drag a normal desktop shortcut into my application, thus avoiding having to recreate lots of application shortcuts.I am pretty clueless as to how to accomplish this, if it is even possible. However, if it can be done, the information i need to extract from the shortcuts are: The name of the shortcut, The associated icon location/file, A description of the program (if there is one), and the executable file location.Also, in the same boat as shortcut drag and drop, just not as difficult- I also am wondering how i could drag and drop ListViewItems into different orders and/or groups.
I have two listviews that uses drag and drop to pass values, however I can only pass the value of my first column. What I need is to pass the value of my two columns.
I don't know what triggered it, but one moment it was fine, other moment it just went like this. Now if I click the body of a textbox, the window behind the application form gets selected.. What can be the reason?
how to read from the first column but I need to read from both of them. I am using full row select which I need on there.Here is the code I am using to get it for the first column.
Dim I As Integer For I = 0 To ListView1.SelectedItems.Count - 1 MsgBox(ListView1.SelectedItems(I).Text) Next
i have 2 listviews in which folder and files are loaded. i'm trying to make a function that, when "Copy" button is pressed copies files/ folders between listviews (between folders "ex: from "D:path" to "E:pathsubpath"). the codes of file copy and folder copy both work but not if add the file.exists / folder.exists lines. if i put a msgbox instead of the filecopy/ foldercopy it displays "file exists" or "folder exist" etc. .. but if add the file copy / folder copy line doens't do nothing.
I am trying to add an unicode character like this one to lets say listview item. I load character from file to string and from string i create a listview item with text same as string () all I get is charater like box.. interesting is that when I copy that character to program supporting unicode I get original char back ().. I tried everything. Searched a lot on internet and forums.. Question bothers me since yesterday, and my project can not continue without unicode support in basic form controls such as textbox.
I found and am using this code to move items from listview1 to listview2.Private Sub ListView1_ItemDrag(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, ListView1.ItemDrag Dim myItem As ListViewItem

I am planning on having 12 - 14 listviews on my form.Do I have to copy the above code and name each source and destination listview for all combinations that I want to drag to and from? Or, is there code that will 'read' the source listview1 name when clicking an item from the list and 'read' the listview2 name when the cursor is on the listview I am dropping the item into.Been searching but probably not using correct terms.
I built a form that has 3 Listview objects. Each Listview contains items, the user is to select an item from a Listview and click a button that moves the item "up" or "down" to an adjacent Listview.I am having a difficult time "knowing" which Listview item has been selected. The problem arises once a user has clicked items from different Listviews. Even though, visually, only one item is selected in one Listview, the program still detects a selection from other Listviews.
Im trying to tackel a forever complicated process of comparing listviews

I am working on an internet cafe program for the desktops. This is how it works, the login files are stored on a ftp server in the form of txt files (E.G. USERNAMEpassword). The files are opened in the background of the program. Then once the login button is clicked, the two text boxes (passwords and username) will combine together and then in the background will look for the username and password as a single line of code.

In order to re-sort the data received in USB easier, I send the data array received in USB (declared as Byte) to a temporary array (declared as SByte) to re-sort. I declared the temporary array as SByte just for easy sorting. After I compiled, an error message came up "make sure not divided by zero". I tried to use convert.SByte but still didn't help. Is it not allowed to send data to an array with different data type declaration?
