2 Listviews & 4 Textboxes Giving Error When Double Clicking On Textbox2 Replacing Data Back-listview2
Jan 16, 2012
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.

Here's the function I'm a bit mystified by(Little rusty bitwise operators)
void two_one(unsigned char *in,int in_len,unsigned char *out)
{
unsigned char tmpc;
int i;
[CODE]...
I marked the two places that I don't quite understand. How to convert those pieces to Vb.Net.
Update: So this is what I came up with, but it's not quite giving me back the right data...Anything look wrong here?
Public Function TwoOne(ByVal inp As String) As String
Dim temp As New StringBuilder()
Dim tempc As Char
[code].......

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?
Here's a screenshot -

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'm new to VB 2008 and was wondering how to apply 2 toned back color to my datagridview column headers or listviews. Where the color is lighter at the top of the column header and then becomes darker towards the bottom of the column header. It seems most apps use them these days.

Im trying to effectively, Save a listviews items to A database (after clearing it) then load it all back in to the listbox, would this do it? becuase it just doubles what ever is in the listbox @ the time,
Dim ConnStr As String = "Provider = Microsoft.Jet.OLEDB.4.0; Data Source = " + System.Windows.Forms.Application.StartupPath + "data.mdb"
Dim DT As New DataTable()
Dim SQLStr As String = "DELETE * FROM [keys]"

Someone asked me to add a function when the notifyicon is doublcliked. I figured that'd be easy with the mousedoubleclick event being available. I find out that then both the single and double will then be called. Well that sucks, I want it to only do the one the user requests. So I tried to get it to work:
Private Sub DblClick_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles DblClick.Tick

Using connection As New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=BankAccount.mdb")

I am using MS Visual Studio 2205 Version 8.0.50727.42 and MS.Net Framework Version 2.0.50727 SP2 I created a form that requires the user to enter a date into the textbox.I then use the IsDate function to check if the entry is a valid date. IF Not IsDate(fieldname) then send message back to user on form, otherwise continue.If something like this is enterred - 06/090/10 - It passes the IsDate question and of course fails at the database level when inserting to a datetime field. Although there is a three character day, it still passes.

I am getting very frustrated with how this was set up. When you are trying to navigate and move things on your form and accidentally double-click, it adds a sub procedure On-Click to the form, then you have to waste time and delete that segment and get back to your workspace.Does anyone know is there an option in the UI options somewhere to change this, so that when you double click it doesn't perform that way? I would like to set it to CTRL-Double click if possible, it would make the program a lot more user friendly for m

I have been scratching my head for a while on this, but not sure if it can even be done. Basically I tried the listbox_doubleclick event but that did not suffice. I am looking for something to use that can run my code when an item in the list is double clicked.It works with the listbox_doubleclick as should, but the problem with this is if I double click the listbox anywhere, it will run the code for the selected item.

i have been working on an app, that remains just my preset sizes. recently, i have discovered that by double clicking the form title bar, even w/the formborderstyle being set to fixedtoolwindow, the form still maximizes and all of my controls remain in the top/left corner.. not a good view.. so, i set the maximum size of the form, and now when double clicking it, moves it to the top/left of my desktop.. not a good result. here is a quick sample to start w/.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
how do i permanently block the double click on the title bar, to have no effect on the form? i do not want to end up w/having to create a borderless form just to avoid this..

I'm trying to finish up Visual Basic project for a class to create a playlist of files and to have them played.I have everything working if I single click the item from my list, and then click the play button in the WMP control portion of my form.I then want to add the functionality of double clicking the selection in the list and play with the following code:
[code]...
and nothing seems to happen.Digging into values of the debugger at the time I try to play the file:
[code]...
The sourceURL of the first item in the playlist is correct, but the duration is 0:00 (it should be 0:01). Since it seems there is no duration detected, nothing is played. Any idea what I missed? Again, if I single click the file, which sets the playlist as I want, then click PLAY on the GUI controls, it works fine.Also, is there any way for the program to detect when the song has changed when playing a playlist of multiple songs? I want to have label fields showing "Now Playing" information that would change info as the songs change, and maybe even change the item selected as things are played. I've not yet found a way to detect this change, only when the player starts and stops in general.
