View 9 RepliesI have a form with a ContextMenuStrip Added and a Listview. I set the 'ContextMenuStrip' property on the listview to my newly created ContextMenu.
So, I am creating the Menu items from a database (no problems here). But I cant seem the get certain menu items to a checked status when creating the menu item from the database.
The Code below is a sample of what I am using.

I'm making a video editor program and I'm getting kinda stumped at the save portion, I've worked with openfiledialog so I figured save would be sorta the same. What I'm doing is adding files(music,videos, and pics) to a flowlayoutpanel. I just don't know how to save those controls made at runtime, this code is my import code. It's pretty much the same for music, video and pics with the exception being the format and openfiledialog being used:

View 4 RepliesIs it possible to save into temp data a user made class? I have a class with many structures and each structure contains variables and im trying to add to my program a way to save the data of that class object with its structures and everything is that possible? I tried manually making some sort of save but its taking too long and proving way too hard for me. Is there a way to just convert it into some general object format and save the object? Is that possible can you just save undefined objects without having to create a format manually for that object?

Then skips straight to the Else without performing the two lines in between, regardless of whether the item was checked or not checked. It doesn't crash, doesn't throw any errors, so I am assuming I coded this wrong somehow.
In a listview with check boxes, there are two fields being loaded, ID and Lastname. With this information I want to get the ID of the person whose box is checked with this sub:

I have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)

I'm making a program in Visual Basic 2008, and I want the user to be able to save certain things on the form. Would it be a good idea to save the saves items to a .txt file in C:WINDOWS? The reason I'm wanting to do this is so the user won't easily find the file and it is easily done.
View 5 RepliesI'm a computer science student and I have a project to do where I need to have VB connected to a webcam to take captures of items and then save them according to the item name that stores them into either a dbase or access database. I have knowledge of oledb using vb to retrieve and modify access databse so it might be better to head in that direction, but I have no clue how to get the webcam talking to vb and see the live feed from the cam until you take a picture and save.

View 2 RepliesThis is probably easy as well. But I have this listview which contains exe files I've listed up. Now, I want to execute these exe files in turn from which items are checked or not. So, I've tried this:
For each item in listView1.CheckedItems
Msgbox item.ToString
Next
Cause I noticed that the item in checkedItems doesn't contain much. And if I convert it to a string, it ends up in the msgbox looking like this: ListViewItem: {Filename.exe}
I have a list of options on my site that a user can select. What I want to do is provide functionality to limit the amount of content the user gets based on his selection in a CheckBoxList. Once he's selected what he wants, he'll click Save and his selection will be written to the database. The CheckBoxList is initially populated from the Modules table. This provides a list of modules that the user can select. When he clicks Save, the code needs to loop through this CheckBoxList and "pick out" the values for the CheckBoxes that were checked, disregarding the ones that weren't. The problem is that whether a CheckBox is checked or not, the debugger returns a False value for the CheckBoxList.Items(i).Selected property.
Here's my code:
Private Sub AddUpdateOrg(ByVal OrganizationName As String,
ByVal Action As String, Optional
ByVal Target As Integer = Nothing)
[Code] .....
Its possible that this behavior is the result of a postback from the save button. Upon further examination of the code, I've reconsidered the possibility that this issue is caused by a postback as the CheckBoxList is not bound on page load.

View 1 RepliesIn my Tools/Options box under Projects and Solutions/Build and Run, I have selected: Before building: to "Don't save any Changes."However, after making changes to a form, I would like to run it without saving, but I get a message that forces me to save, unless it runs the version of the program before the changes were made.The VB 2005 edition works the way I want it to allow testing without saving, but VB2008 does not allow this.Is there any way I can change this behavior?

Does anyone know of a control such as a Checked List Box where each item can have a value against it.For example you have a list of fruits and in the listbox it displays Apple, Orange & Banana but the values for those items are A, O & B.
View 3 RepliesWith my CheckedListBox, I am trying to get the text of each item that is checked and add it to a listbox, but it does not get everything currently checked. If I have 3 items checked, it only adds 2 items. If I deselect an item, it appears.

The check box list has an event called "ItemChecked" or something, which triggers when an item is about to change its checked status.
So, it is before the check occurs.I couldn't find an event that occurs after the item has changed.. I want to execute some code only when an item is checked or unchecked.
I want to adding checked item from checkedlistbox to my combobox, but i have a little problem here.Combobox only show 1 item last checked.This is my sample code.

cbCheckedItem.Text = CheckedListBox1.CheckedItems(i).ToString

I remember doing this in a checkboxlist element, but with listview element its giving a hard time.

For index = 0 To Me.ListView1.Items.Count - 1

I have a list of items in a ListView and at the top of the list there is an item that is supposed to select all the items in the ListView. I can get it to select all of the items when it's checked but then I can't deselect any other items. I need the to know which item was checked, when putting the sender into a message box I get "System.Windows.Forms.ListView, Items.Count: 1, Items[0]: ListViewItem: {All}". How do I get the sender's item?
View 6 RepliesI have a checkbox list which is filled with entries from my database on page load. I need to update an entry in my database when a item is checked and when an item is unchecked. Right now I am doing the following:
<asp:CheckBoxList id="check1" AutoPostBack="True" TextAlign="Right" OnSelectedIndexChanged="Check" runat="server">

And the function:
Sub Check(ByVal sender As Object, ByVal e As EventArgs)
Dim sql As String
If check1.SelectedItem.Selected = True Then[code]....
The error is: "Object reference not set to an instance of an object." Is there a better way to check if a list item is checked or unchecked?
