Deleting Items Off Completed List By Checking A Checkbox?
Apr 16, 2012
I have an invoice that lists several items that one person has ordered. I want to take this invoice and every time I check the item it removes one of those from another list i created called item details. I added items to this list using the item collection in the listbox.. I have invoice one that has a pink sock ordered. when i clicked this box next to it I want my total pink socks of 12 to move down to 11... the detail page and the invoice are two separate pages.
I have a checkedlistbox with numbers in it and I'm trying to load a list of numbers from a database and check all of them (they should all be in the checkedlistbox).
I was trying to do this by loading all the values into a separate listbox using my own subroutine (I know that part works) and then finding the corresponding item on the checkedlistbox, like this:
Dim ItemName As String For Each item In ListBox1.Items ItemName = ListBox1.GetItemText(item) If CheckedListBox1.Items.Contains(ItemName) = true Then CheckedListBox1.SetItemChecked(CheckedListBox1.Items.IndexOf(ItemName), True) End If Next End If
But this doesn't work: It never returns a match, even when the item is definitely on the list. How do I make this work?
I want my program to check the pagerank of all string list items, and than add it do a listbox. Now this is my code to open a list and add it to a string list ( itemlist as list(of string)
Dim stream_reader As New IO.StreamReader(OpenFileDialog1.FileName) Dim line As String line = stream_reader.ReadLine() Do While Not (line Is Nothing) line = line.Trim() [Code] .....
I'm using the DLL from this website: [URL]. The problem is that it only checks the first website and the other websites will be 0/10 automatically while they might be 3/10 or something else.
if i pressed the RadioButton .. ENGLISH.. only Teacher's which teach English will be displayed in the listbox and so on. there is in access table called TEACHER which has all these information. i used the following code for displaying the TEACHERS' name in listbox and it worked pefectly but what i want is displaying according to radiobutton checked.
Sub conxn1() Connection.Open() Dim da As New OleDb.OleDbDataAdapter("select * from Teacher ", Connection)
I've never really used the Check List Box in the past, however, for the recent program I am developing, I am using this control rather than individual check boxes scattered across the form.Anyway, I want to be able to program through code which items get checked in this checked list box. Specifically, I have a variable that contains the text of each check box that I want checked.With a normal check box, I can simply say:
Dim strNames As String strNames = "John Doe, Mark Johnson, Mike Brown, Cindy Smith" If strNames.ToString.Contains("Mike Brown") Then[code]....
Could not find this through Google or in SO questions.I have a checkbox listbox on my form. I want to filter my List by the list of selected Ids from that listbox that are checked, in SQL I would have done this like "Where TypeId In (1, 4, 5, 7)"... how do I do that in LINQ?
I feel like I am missing a really obvious answer, but cannot get it.
For argument sake... here is the what I have for sample data:
so im dynamically populating a checkbox list. I have confirmed that my text and values are correct for each checkbox but when I check a few and click my event button when I loop through the items they are all set to select=false...
Dim resource As ListItem Dim SelectedHashTable As New Hashtable For Each resource In chkResources.Items
I have a ListView with Checkboxes in vb.net and what I want to do is when the user check the checkbox, the program ignore the response of the user in checking the checkbox, instead it leaves the checkbox uncheck.
Im doing a small project in visual basic which involves lighting up leds through the parallel port and turning them on and of. each led is controlled by a checkbox on my form and they only come on when the checkbox is checked.
what code do i need to use to have the checkbox checked when a key is pressed but when the key is released the checkbox is unchecked i have already tried keydown which will check the box when a key is pressed but will not uncheck it when the key is released
If e.KeyValue = Keys.A Then CheckPin1.CheckState = CheckState.Checked ElseIf e.KeyValue <> Keys.A Then CheckPin1.CheckState = CheckState.Unchecked End If
I've been going round and round with this and thought maybe someone would know.I've created a program which with process.showdialog calls up a form into which the user enters username and password then is given access to the program itself. If the username and password is incorrect, the program closes.
There is a frmMain and in the form load I've added the process to open this sort of splash login screen. It's not a splash really, it isn't timed to close down.
I fill out the login information, click the save settings checkbox which creates a settings file in MyDocuments. My problem is that in debugging, removing the click closes the login page without the click actually becoming unclicked. The Main program opens before there's been a chance to register the "unclick." Hope this makes sense.
I am trying to detect whether a checkbox is checked and display a message for the ones that are.I am running Visual basic 2010 and The code is as follows: Dim message As String If CheckBox1.Checked = 1 Then 'MsgBox("Checked") message = message & CheckBox1.Checked & vbNewLine MsgBox("You Have Choosen" & vbNewLine & message) question is what is wrong with this code? I get an error that message value has not been declared.
What would be the syntax to check inside a visual basic form panel for checkboxes and find which are checked? I understand how I Could use a for loop and an if statement, but I'm confused as to the syntax to check for each checkbox. for example:
Dim i As Integer For i = 1 To 10 'Here is where my code would go. 'I could have ten checkboxes named in sequence (cb1, cb2, etc), 'but how could I put i inside the name to test each checkbox? Next
I have a question regarding the checkbox. Here is the scenario: I have three groupboxes which I have initially set as invisible. I have three checkboxes out to the side. If I check a checkbox, is it possible to have one of the groupboxes become visible just by checking the checkbox and nothing else. (I mean without clicking a button or anything, just clicking the checkbox and then having a groupbox become visible).
I have agroupbox control and on this groupbox control there is upto 10 checkboxes, if any of them are unchecked i was going to throw a warning "No checkboxes selected" i'm not sure how to go about it so far i have:
For Each ctrl As Control In GroupBox10.Controls 'Not sure what to do here... Next
OK, to make a long story short, programmatically generated data is taken back to the original page and the goal is to have this information cause checkboxes (hard coded into the aspx page) become checked.
Using feedback, the exclamation below confirms that I want the found control ctl to be checked:Dim ctl As Control For Each ctl In form1.Controls

I'm not sure what to put for XXX and my gut feeling is this is really easy. ading my question. I went through pages of search results on "VB Programmatically check checkbox" and found pages that should have had an answer that worked
How do I put webbrowser1 put checkbox checked pressing button. Checkbox <input type="Checkbox" name="n10" value="3685551"> Note! Website what is showing in webbrowser WEBSITE's Checkbox.
I have 5 checkboxes in total.I want to check how many checkboxes have been checked.I dont want to write checkbox1.checkstate,checkbox2.checkstate and so on...How do I accomplish this effectively?
I have two checkboxes in a windows form, one is called New Assumption the second is called Edit Assumption. What I want to do is that if either of these checkboxes are checked then the other should be unchecked.
I have tried using the CheckedChanges event, CheckStateChanged event and Click Event for each of these checkboxes and these events dont seem to be activated anytime I click the checkboxes.
What event and code should I use to uncheck and check checkboxes programatically based on which checkbox a user clicks on?
There's a combobox with questions and a listbox with questions of the chosen answer(s).I have already to add and show the questions, answers.Now I wan't to delete the answer(s) (in the listbox) of the chosen questions I have this already
con = New OleDbConnection(providerStr & dbLoc) con.Open() Dim command As New OleDb.OleDbCommand("DELETE FROM Answers WHERE questionId= " & 0 & " AND answer='" & lstAnswers.SelectedIndex.ToString & "')", con)
My program takes a checkboxed item and depending on the serial number that is present on the item on the invoice, subtracts one from the amount list I have the following in a listview on a details page which I added with the following code:
Right now it doesn't look like it does anything. I have tried changing my index's on my subitems to 1 and 3 instead of 0 and 2 but i figured because they are subitems that they need to be subitem index 0 and subitem index 2 since there is one item and three subitems to that one item.
i am running into some difficulty with the .NET garbage collector. i have a custom control that i need to dispose and reallocate depending on user interactions. calling ctrl.dispose() and then instantiating a new control accomplishes what i want, with the nasty exception that the garbage collector (at least, i am presuming this is the GC, since this exception will happen on it's own after the application has been idle in the background for several minutes) will then periodically throw an exception: "cannot access disposed object
basically i had this problem before which i fixed with this code!
'REMOVE TIME If ListBox1.SelectedIndex <> -1 Then Dim Box As MsgBoxResult = MsgBox("Are you sure you want to remove this time?", MsgBoxStyle.YesNo)
[Code]....
It worked perfectly, all ive done to my code since is change the way the listboc is loaded / saved, it now comes from a .txt in My Documents rather than the C drive.
It now only deleted the top value of the group selected int he listbox and not all of them as it did before.
OK so I did a noob screw up, I was cleaning my application and delting unused data sources and unused data bindings. Now my form is blank! All code shows up for the form and all items still show in the mainFrm.Designer.VB
I have this code to check if an item from a textbox is in a listbox and its giving me the error at the bottom.I copied it from another part of my project and it was working for that part so I cant see whats wrong.
If LocationsSearchTextBox.Text <> "" And LocationListBox.Items.Count > 0 Then tempInt = 0 While (tempInt < ClientListBox.Items.Count)[code]......
I have a CheckBoxList where one of the options includes a textbox to fill in your own value. So I need to have that textbox become enabled when its checkbox (a ListItem in the CheckBoxList) is checked.This is the code behind, I'm not sure what to put in my If statement to test if that certain ListItem is checked.
Protected Sub CheckBoxList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBoxList1.SelectedIndexChanged If ___ Then[code]......
If Form1.ListBox1.Items.Count = 0 Then Else Dim classSS3 As New StringSift3 Dim ReturnVal As Single
[code]....
What im trying to do is the returnval works its a compare percentage, dont worry about that. lb1 is the index of listbox1.selecteditem which is the first item, im trying to make it check the childnode for each root node in the treeview.but i get an error on.Form1.TreeView1.Nodes(Form1.lb1).Nodes(classItem).checked = True saying..Object variable or With block variable not set.
