I cannot figure out how to add an item to a listbox with a specific value. I am able to add a text description without any problems, but how can I give it a specific value?
For the last couple of days I been trying to add items to a listbox from another class within a system.timer.
They just don't appear in the listbox. I don't get any errors. The items just don't get added :S.
I have:
Form.vb make object of Control Control.vb Here I have a system.timer
In the Timer_Elapsed method I do this: form.listbox1.items.add("hello")
But it just doesn't work... When I add a new item to the listbox1 from the constructor or another method that has nothing to do with the timer it works...
I have been out of VB since VB 6, but am back into it to write a basic app. I have created a listbox and am able to add data to it from a textbox via a command button. However, I want to give the user the option to simply press the enter key after they have entered the info the textbox, instead of clicking on the command button. I tried calling the function the command button is using from the "ENTER" event on the textbox, but all that does is execute the function when I click on the textbox? I'm sure this is very simple. What am I missing?
How would one go about checking a listbox's items for duplicates? Basically I need to write a program that displays the teams from a text file provided by my instructor, in alphabetical order. I can do that, but what I can't figure out is how to prevent the For loop from adding a duplicate team. What I'm envisioning is:
If teams(i).name is not in lstTeams.Items Then lstTeams.Items.Add(teams(i).name) End If
I have a program that compiles and works so far, except for the above problem and my alphabetical order (which I can probably figure out on my own:
Public Class danbrockteams Structure team Dim name As String
[Code]....
This works except that my listbox is filled with the team every player is in rather than just listing all possible teams. Not exactly looking for someone to just give me the answer, as I understand things best when figuring them out on my own, so I suppose a hint is what I'm really after.
In my application I have a listbox and SelectionMode should be MultiSimple because users need to see which items they selected. In another tab we have another listbox this one should show all the selection users had done in first tab. Private Sub
where to start on making a button on my form to search for records in a database.I know how to do a filter on the navi bar to say search for lastname records,but i want to add the button to the form to do the search.
How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.
Public Class Form1 Const dcmPRICE_STRESS As Decimal = CDec(595.0) Const dcmPRICE_TIME_MANAGMENT As Decimal = 695
removing Listbox item from checked Listview item.The code I tried just errors out.
Private Sub ListView1_ItemCheck(sender As Object, e As System.Windows.Forms.ItemCheckEventArgs) Handles ListView1.ItemCheck If (e.CurrentValue = CheckState.Unchecked) Then ListBox1.Items.Add(Me.ListView1.Items(e.Index).Text) ElseIf (e.CurrentValue = CheckState.Checked) Then
Is it possible to select an item in one listbox and then display the data of another listbox with the same indexed position? I am planning a project and this is something I would like to attempt but I haven't figured out how to do it.[code..]
I tried doing the above code but instead of displaying the listbox text the message box just returned false.
problem that i am facing is i want to add array of object as a single item in listbox. in vb6 i was using this Label1.Caption = Label1.Caption & Mid$ (strInput, intI, 1) & " " List1.AddItem (Label1.Caption) i was using label. caption to store object but not work in vs2008 because label.text only take text and left other values
I have 2 listboxes on my form.Listbox 1 - populated with "available" field namesListbox 2 - populated with "selected" field names.There cannot be the same field name in both listboxes - it's either one of the other.The logic I was going to apply was to populate Listbox 1 with every field name ... and then as I populated Listbox with the field names which the user has already selected, remove the corresponding item from Listbox 1.
Just want to ask this. I have a jQuery that move listbox item to another listbox. An its working fine the item was remove. Sample: I remove item in listbox A and it was added to listbox B. But here is now the problem, when I tried to check each item in listbox A, I noticed that all items that was removed was still there. But i can see in my eyes that it was removed. but when I tried to run a code to check each items - all item that was removed was still there.
I want that clicking the btn1 it shows the OpenFileDialog and read file that it has got this structure: SKI10 1 71 0 0 18 101 19 0 29 101 30 0 40 101 41 0 50 101 51 0 62 101 63 0 81 101 82 0 95 101 2 0 0 95 165 3 0 1072 01 4 2 1 93 15
I want that it reads all Line of the File and it add an Item in ListBox for line.For example the first Item of the ListBox in this case is
SKI1
And the 2th Item is in this case.
0 1 7
I want using the StreamReader classes.And i want that when i click an Item of the ListBox it shows the Text in the TextBox and I can edit the Line and that clicking antoher button the Item will come updated with new Text of the TextBox.I have also another button for saving the Mod.I can use the AppendText and it create a new file writing ListBox1.Items line for line.
If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then Dim file_esistenteD As StreamWriter[code].....
I have a multiple form application with a listbox on each form. I want to be able to select an item in one listbox on one form and then click a button and it show up in a listbox on another form.
I'm trying to make a program that adds a menu item when right clicking files.I got a C# code here:[URL] and converted it to VB. It's working perfectly but the trouble is, it adds a menu item to folders and not files.
These are the registry entries i added:
Private Const MenuName As String = "FoldershellNewMenuOption" Private Const Command As String = "FoldershellNewMenuOptioncommand"
I am using ASP.NET with VB.NET as background code. I have 8 ImageMaps in my webform Estimator.aspx.Each ImageMap represents a car part (Front Bumper, Rear Bumper, Mirror, Hood, Sunroof, DoorShell, Headlights, Tail lights) and I have a dropdownlist ddlChosenParts. When the user clicks on any of the 8 ImageMaps, I add the PostBackValue to the dropdownlist ddlChosenParts.The problem is that if the user clicks on the same ImageMap twice, the PostBackValue is added twice.I want to check if ddlChosenParts contains the ImageMap's PostBackValue and if it already contains it, do not add it again. That means that if the user clicks more than once on the same ImageMap, it's PostBackValue is only added once in ddlChosenParts.I have this code but i'm getting an error: Value of Type String cannot be converted to ListItem. [code]
I have an Access database with a Parts table. I'm using tableadapters in my project. A datagridview on my form is filled manually in code. One column of the DGV contains a columntype of combobox. I've got a bindingsource on my form whose source is the Parts tableadapter. The combobox column is tied to the bindingsource and is displaying fldDescription.
The part descriptions can be changed by the users, but the original part description is saved in another table that is used to fill the grid. If part "widget" gets changed to "widget, large" I can no longer display "widget" in the combobox of the grid. I need to know how to be able to add it to the bindingsource so I can display it in the combobox. I don't want it saved to the Parts table though.
I'm new to databasing. How do you make it so you can add an item to a database on a form, Then follow a link to another form which has the database on, then what you put in on the previous form will be there?
How's it done? Sorry - Haven't been using VB very long >.<
I have made it so that as soon as the form opens it puts an icon in the tray and when you right click the icon it comes up with a contextmenustrip. in the form I have put a button and a textbox. when you click the button, it creates a new item in the contextmenustrip What I wanted to do was add a peice of code to this new item, is this possible?
I have an app that I have made. The application generates 14million combinations of numbers and inserts them into an Access Database. As you can imagine, this takes AGES (whole night) to compute. Is it possible to make the same method call twice so instead of one combination being generated and inserted, two or more are?
i've written a database program which runs fine from the ide (vs 2008). when i install this program, all database operations do not work. i tried running it as an administrator using an admin command prompt, it worked. now for my less tech savvy clients, is it possible that when they right click the programs icon they can use the 'run as administrator' menu item? how can i achieve this. if it's too much to implement, will moving the database from the application path to, say, documents, solve this issue?
In WinForms, is there a way to add an item to the popup menu when you click on the icon in the forms control bar? Apps I can think off that use this is Chrome, and Command Prompt.
