I have been given the following piece of code which allows a checkbox selection to be made and an associated piece of text be printed in a textbox.
How would i be able to do exactly the same thing but for a listbox?
Also how would i be able to get something to clear from the listbox when then checkbox is unchecked without getting to complicated?
I've wondered if i can make it so when i click on a checkbox you may not beable to check another. And i do not want to use radio buttons

I've been making a scheduling program using the calendar object.I can manage to select any date with a single click with a message box pop up entering a memo for the date selected. After pressing ok, the memo is displayed in a list box, with date.
1.Unfortunately the date is being displayed twice - perhaps because i used .selectedrange in the handler ? i would like it to be listed only once
2. the memo comes up on a separate line, ideally id like it to be displayed on the same line as the date.i tried ListBox1.Items.Add(whendate, memo) but it cant compile, so ive had to put each line in seperately
3. I would like to mark the sundays and national holidays in red color (the calendar is only set for a year so i dont mind doing them by hand, however the only tool i can find in the Monthcalendar1 properties is MonthlyBoldedDates, and no color assignment [code]
I am doing a lab where you have to connect to the database using the Database Configuration Wizard in Visual Basic (Visual Studio 2008). The database connection is there since the form will display the records.The problem is the user is supposed to be able to click on the combobox arrow to select a stock rating (high, low, etc) and then the listbox will display only the stocks with that rating. I thought this would work but nothing is showing up in the listbox.
' strSql is a SQL statement which selects all the fields from the Team database.

View 39 RepliesI am creating a program with multiple Forms designed to track multiple projects.The first form is designed to setup new projects and obtain previous projects, from there the other forms open to be filled in with information.For new projects the next forms open blank but I then need these later forms to be tied to this project name so that it can be selected from a combobox and the information will be already populated.tieing the information on the later forms to the projects populated in the combobox so that it appears when a specific project is selected.Is this able to be done without creating databases?
As an example, say I create a new project then a new form opens and I add some information to a textbox.I would then like to be able to save the information so that the project name moves to the combobox on the first form (I can handle this) and the information input in to the textbox is tied to the project name so that when the program is reopened and the project name is selected the second form opens with the textbox populated.
i am working on a program that has a randomize button that can already randomize the selection of a listbox. Now i wanted to make it also randomize the selection of a listview, but i can seem to find out how to do this. Ive tried using the same code, but it said that add isnt part of listview.

ive just registered but ive been reading this forum before.I have a medium problem and an easy problem.
My project adds dates in runtime to a listbox.It can be any date inputed by the user so theres no way to know which date is at which position thats why the listbox index stuff for me is totally useless.Problem 1: if lets say a user types in a date into a textbox "27-03-2001, and press an "OK" button, i want to select that date automatically in the listbox if it exists.the only way ive found so far to programatically select an item is to use the index stuff which as i said is worthless for my situation as the comparison is a string,So, how can i select an item from the listbox using a string to item comparison?
Problem 2: Dates in the listbox are dd-mm-yyyy format so they dont arrange properly, is there anyway i can make the listbox sort the items counting from right to left instead of left to right? because that would solve my problem as it would be like inverting the date itself while sorting.
if you can answear any of these 2 problems please dont hesitate to comment about it, if its possible or not and if it is how i can do it.Both problems are at the same importance for me
I have a question regarding Databound listbox (Item selection)I have not used the listbox much so I am very uncurrent in it's use:What I am wanting to to is connect to a database, select from the database (lastname) then display the list of names in the listbox, also have a datagrid on the same form, so that when I click on a name on the listbox the datagrid moves to that same record.
View 5 RepliesBasically I have a list box with a collection of strings. The way it works is you select an item from the list box then enter an integer into a text box and it calculates, straight forward.Where I'm getting tripped up is I'm trying to implement a 'Reset' button to reset the list box and text box. The text box is straight forward as is clearing the selection in the listbox:[code]I understand that since there is nothing selected the index is getting tripped up or whatever but I don't know how to stop this. I'm new to VB and programming in general and have been googling for days trying to get this fixed to no avail.

I've already got the code to populate the listbox by a button click from the user and am just trying to figure out how exactly to alter the text of a label based on what the user selects in the listbox.
