Autoselect Pre-programmed Items In A Listbox When A Form Opens With The Control On It?
Aug 3, 2009
I am trying to autoselect pre-programmed items in a listbox when a form opens with the control on it.but i cannot find a proper method to select all the items in the listbox and hold the resulting text as a string that will later be saved to a text file. i do not need help with saving the text to file but rather selecting the items in the listbox.so, after alot of trial and error and no luck I think I am supposed to use
ListBox.ObjectCollection
propriety. but i have no clue whats so ever in how to manage to select all the items in the listbox when this form opens...if this does not make sence then I will rephraze it.
I am new to these forums. I had a VB.net class several years ago and cant seem to find this info in the text from the book used in the class. Here is what I would like to do. I have a 2 forms. One with three buttons and the other with a listbox. When I click on one of the three buttons (on form1), I want to fill the listbox (on form 2) with one of three arrays. is this possible, it seems like it should be.
I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
I have a form with a Tab Control that has 18 pages. When I click on a tab it opens the page and select a textbox on that page (txtTextbox1. Select() ). This works for the first 8 pages but not for the remaining 10 pages. Although on these pages I can mouse click on the textbox, enter info, save then click my Add button that clears the textboxes and has the code (txtTextbox1. Select() ). The textbox is selected just fine. The code for all my pages is the same except for the tab name and the control names. The tab key will move the selection to the next textbox in order on all pages and the Enter key is coded to do the same. The first 8 pages have a total of 256 labels, buttons, list boxes, textboxes and checkboxes on them.
As far as I know, there is no way to grey out/disable specific items in the ListBox control? I want to make a list of surveys that need to be answered, but grey out/disable those that the user has already answered.Or is there some way to do it with ListBox?
How can you add items to a listbox on a form? Also this needs to be included so if another item is added by user it will be added directly to database.
Reason i am asking that is my project has to work in cojunction with Oracle Plus.
So far if i remember it is something like
.Add("Horror") .Add("Romance")
I'm unsure if that is correct but i want the items to appear so the user can select one from list.
I think you have to include a data reader but don't mind that i can handle that. All i want is to add items to listbox when form loads.
I have two forms with one listbox on each form. How can I show what I have in the listbox on form1 on form2. I have a button on form1 to go to form2.
Private Sub btnform2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnform2.Click Form2.Show() Dim sTemp As String = TextBox1.Text & ":" & textbox2.Text & ":" & textbox3.Text & ":" & textbox4.Text & ":" & textbox5.Text Form2.ListBoxFonts.Items.Add(sTemp) 'add to the listbox End Sub
But when I click the button it goes to the form2 but it only shows one list and nothing else. When I go to form1 to add another list, it comes up with the listbox on form2 with two list, but when I go to my form2, it only shows the latest one I put in, it never shows two or more list, its probably just one line of code.
'Form 1- start a new thread and declare a new second form. Have it invoke before adding an entry. as this apart from "CheckForIllegalCrossThreadCalls = false" is a workaround.
Code: Public Class Form1 Dim t As New Thread(AddressOf startanew) Private Sub startanew()
Our chapter is all on printing, but the teachers example sends the data to a new form, into a listbox. How do I take the contents of a ComboBox from one form and input it into the ListBox on another form, first adding the line "High School List".
I have this much, but then don't know how to read fromt he ComboBox. Not what is highlighted, but the full contents.
FrmPrint.Show() FrmPrint.LstPrint.Items.Add("High School List")
I am using Visual Basic 2010 Express. I have 2 forms. A main form which does all the grunt work and then a small supporting form to get some additional user inputs.
Some program background...I am developing a program to characterize solid rocket motors based on test stand data for a hobby project. I load the time, thrust data into lists via a streamreader from a text box.
However, since the data is raw I would like for the user to select the "start" and "end" of the burn. I am currently trying to do it right after I load the data. As I read the data in, I just put it in the listbox of the supporting form as well. My main issue is, I need two values from the user. A start and end time. the index would probably be easiest, as I will rewrite the data list based on the time increment and delete everything before the first listbox selection and everything after the second selection. I can't get the values from the main form. I have exhaustively searched the internet trying to find something that I can apply. If someone could help with a framework on how to do this.
I understand how to get text from this text box on a different form, but this deals in variables and maybe setting up a class? I am having trouble communicating between the two forms.
I have a webbrowser I'm making, and my listbox items for form2 disappear once I close form2 and reopen form 2. However, once I restart the program (Close everything) and re-enter, the data is saved. But once I reopen the selected form, the listbox items are lost. Here is my code (It's long)
i have two forms, one form is for accepting the details of the customer and other form is to export the customer details to excel. In the second form i have a listbox which contains all the names(rather captions) of the controls on the form1. like Items In Listbox -> Map onto control of Form1 customer Name -> txtcustomerName Address -> TxtAddress. What i want to ask is what is the best way to get the values from the form1 based on the selection(s) of listbox in form2
I have some info in a listbox on another form. I want that information parsed to another form, and I would like to, for how ever many items there are in a listbox, create a button for every item and obviously parse the name to another label. I guess I would do this via an array.
I need the user to choose one on a group of RadioButton controls. The problem is that on form load, one RadioButton is automatically selected. I does not want one selected, unless the user checks it, but cannot find how to disable automatic selection.
I have a form set up with a few text boxes for first name last name and job title and i got the class for EditDialog. vb. The question is I have to drop some controls onto the form to make a generic add and edit employee dialog. Now would I use the listbox or drag and drop control?
I'm trying to add a code,so that I when an item in a listbox an apllication will be run.A user inputs a name for the listbox eg "hello"Then the user specifies the path of the file to be run. The name will be fixed.eg : test.exeIf the user then says the file test.exe is locted in C:mygame, he will point to that path.NameGame = textbox name where user inputs the name that should appear in the listboxSearchbox = textbox to allow users to search through the listboxEntryBox = box where the path appears, just for checkingI know I can load a folder with this :
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadFolder.Click Dim FolderBrowserDialog1 As New FolderBrowserDialog
I'm just starting to write a program to manipulate some intranet based databases using the web browser control, but have a problem with one specific database.I can log in from the start page of this database from my browser but it then opens in a new instance of IE (I think it's the java code (not java script) which does this when the page loads).How do I get it to open in my browser?OK, I can manipluate it with a doc object, but would prefer to do it in my browser for consistency, as the other databases open fine in my brower.I can't be more specific but could post the html text if necessary.Currently using the built in web control with VS2005 running on XP.
I have 10 textboxes on a windows form. Each textbox has the same contextmenu. Say they are named textbox1 - textbox10. What I need is when I right click in one of the textboxes I need to capture the name of the textbox in which the contextmenu was called. So if I am over textbox2 and right click for contextmenu then select menu item #2 in the click event I need to capturethe textbox control I called the contextmenu from (textbox2) so I can send that name to a function to process my other code.
I have a form ( call it NewForm ) that can be opened from many other forms, but I don't want to have the user to run into the problem of having many windows/forms open.I want to close the calling form and open NewForm.NewForm will prompt the user for information, but if the user doesn't find what they are looking for I want to have a "Cancel" button on the form. With the "Cancel" button I want to go to the previous form.is there a way to tell which form called NewForm so I can just reopen/unhide that form/window.
When I initialize a new form to open, the subroutine in the new form starts before the new form is shown on the screen and so when the subroutine finishes and the MsgBox comes up, the form isn't showing.
Is there a way to make the form pop up first before the subroutine starts?
I am using VS 2008, Windows XP R3, and Visual Basic.When I open some forms in the form designer, (In Solution Explorer, right click on the form, then select View Designer) the form always opens as Edited. An Asterisk "*" appears after the form name in the open window tabs. If I open the form to just view the code (In Solution Explorer, right click on the form, then select View Code), the form opens normally. This happens for just some forms.
It always happens for the same forms, and never happens for the other forms. What I am missing in those forms where the designer always thinks the form has been edited?
When opening a button and opening a new form as soon as it opens it close for some reason but its not giving any errors as to why its doing this now I've checked the linked linking it to the next form that's fine.
Private Sub PrintPerscription_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Login.con.Open() sql = "SELECT Patient.* FROM Patient where Patient.Wardno = " & Login.WardNo.ToString da = New OleDb.OleDbDataAdapter(sql, Login.con) noOfRows = da.Fill(dsPatient, "Patient") [Code] .....
I am trying to populate a a listview control with items and subitems that a user enters into a group of textboxes on a form. It looks as if some of the code to do this has changed since VB6 and I am confused again. Here is the current code I am using without success:
lvSurgProcedure is the name of my listview control Private Sub btnAddSurgeProcedure(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddSurgProcedure.Click Dim lvItem As New ListViewItem
