VS 2010 Combobox Selection Alters Checkedlistbox Contents

Feb 23, 2012

I am new to the forum and to VB, and not great at coding in general.I am learning, and this site as well as others have helped me get farther than I ever imagined. Second, my project is purely for my benefit, so I can learn.There is no corporate or school related goal here, just trying to learn.So the title is a summary of what I want to do. I have a form with a combo box that has five different choices, and below it, a checked list box. What I want is the collection inside the checked list box to change depending on what I select in the combo box above it.For instance, I have room 1 - 5 in the combo box, and the the checked list box below it, I have the furniture associated with that room.The eventual goal is to have this form populate a database, that allows the checked furniture to be recorded in a record.

I assume I need to use a db, such as access, to list the "furniture" in each room, and have a different table for each room, where the combo box selection will populate the checkedlistbox from the appropriate tables contents.I need a step by step on this, because I am a bit of a brick. Most tutorials are also done in VB 6 or VB 2008, and there have been steps missing in association to VB 2010.

Make Selection In CheckedListBox Exclusive?

Apr 29, 2009

In an application I build a list of CheckedListBox and display it to the user. I want to make the selection exclusive to only one. I noticed that you can check more that one item in the CheckedListBox. How can I stop that and as the user check the second box I uncheck his/her first selection.

SForm.ChkBoxPts.Items.Add("Paarsa")
SForm.ChkBoxPts.Items.Add("Jeff")

I.e. If I display the above two items or may be even more, I would like to force the user only select one and only one.

Multi-selection Is Not Supported On CheckedListBox?

Oct 21, 2009

I am creating a Windows Form exe using VB2008. The documentation for VB2008 says "Multi-selection is not supported on CheckedListBox". But it works very well in debug mode. I cannot change the properties of the control in the IDE but I can run the following statement (clbProj is a CheckedListBox control) in the load event and it implements the multi-selection on the control.

clbProj.SelectionMode = SelectionMode.MultiSimple

I run many tests in debug mode with this option and it works every time. The program processes every checked item in the list and works as expected.

However, when I compile the program and start the exe, it throws an error saying "Multi-selection is not supported on CheckedListBox".

VS 2010 Combobox Changing Selection Disables Button Again?

Nov 19, 2009

Ok so i'm trying to set up my program so that when I choose WinRar it opens a new window asking which architecture to use. I have a combobox set up with both architectures in it. I have the accept button disabled so that you have to choose an architecture and I figured out how to make it so that when you select one architecture it will enable the accept button but if you choose the other architecture it disables the button.

Private Sub cmbx_rar_wdw_arch_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbx_rar_wdw_arch.SelectedIndexChanged
If cmbx_rar_wdw_arch.SelectedItem = ("32-Bit (x86)") Then

Make Checkedlistbox Value Change By Selection Of Combox Value?

Nov 3, 2011

I know that sounds strange but I came across this website today that uses this ability and I've been going nuts trying to figure out how they do it.

The website is [URL]

Also here is a screenshot of the options I am speaking of

There is a combolistbox that has a list of topics.

Depending on what topic you choose will determine what checklistbox option will appear in the check list box.

What are they doing there to create that option? I was thinking that maybe they created 20 checkedlistboxes and then if the selection of the combolistbox is "THIS" then they set the getfocus to that checkedlistbox but that didn't quite work for me.

VS 2010 Populate Textbox With Excel Data Based On Combobox Selection?

Nov 29, 2011

Visual Basic 2010 Express: I have a form with a combobox that is populated with the names of locations from a datagrid which in turn was imported at run-time (Form_Load) from an Excel database. The Excel database (and the datagrid) also stores the information for addresses and phone numbers for their respective locations.

What I would like to do is have the phone number and address text boxes automatically be updated with the proper corresponding data when the user selects a location from the combobox. Whether the text boxes are updated from the datagrid or Excel database is not a concern; I'm mainly looking for whichever way is simpler.

Unwanted Selection Of All Contents In Textbox

Feb 10, 2011

I'm using VB 2005 and MS Access 2000. I have a process that does some "stuff" with the data, re-queries the database, re-populates the form then displays a messagebox indicating that the process has completed. My issue is that after clicking OK in the messagebox, that whatever textbox the cursor was in prior to starting the process, now has all the text in it highlighted. If I don't show the messagebox then this doesn't happen. And if I don't call the process that repopulates the form controls, this doesn't happen. There's no code in the app that selects the contents of the textbox so is there a property somewhere that controls this?

Adding CheckedListBox To ComboBox?

Jun 9, 2009

I'm trying to implement a combobox that will drop down and give a list of things that the user can select via checkbox so that they can have all, none, or some of the items selected/implemented in the program. Through some research, I've come up empty handed. I found a few tutorials that dealt with tons of class files, which I'm not really familiar with, didn't understand much, and then didn't work. Who would've thunk it right?Anyway, i tried just adding the checkedListBox as a control to the comboBox and it would disappear from the form as if it had been added, but wouldn't show up from the comboBox drop down menu..can anyone tell me how I can go about doing that?

I have a combobox which contains a sample of names selected from a table.Currently the default name displayed in the box is the 1st name found in the table. What I would like to do is display the name of the person who is doing the selection as the default.

Combobox - When Select A Value From The Combobox The Selection Won't Validate?

Feb 22, 2012

I'm having a problem with combo boxes. I usually use Java and it's been awhile since I used VB but I never remember having this much difficulty.My application is using an SDF file. From Data Sources, I drag the details on one of my Tables to my Form to get all of the fields. Three of them are comboboxes. Each of the three is an INT64 and each corresponds to a primary key in a different table. I click the tasks button on a combobox and for data source I select the appropriate table that has the data to go with the combobox, for display member I select the field that I want users to see, and for value member I select the primary key. Then I run a quick test and start the app, open the form, and add a new record. When I select a value from the combobox the selection won't validate because it doesn't think it's an INT64 like it should be. It seems to be using the display member as the actual value instead because if I change display member to the primary everything works great.

Filter Combobox Contents By Text In Another Combobox

Jun 22, 2010

Brand new to VB 2008 Express, but have done some work in VB 6. Not sure what I'm missing, but here goes. I have two comboboxes linked to an Access 2007 database. One box lists the names of the States in the US.

This is what I used for the Table Adapter Configuration Wizard for the combobox "State" SELECT ST_UID, ST_NAME FROM STATE

For the combobox County I used: SELECT ST_UID, CTY_NAME FROM COUNTY ST_UID is an Integer.

I created a label with a bound value to STATE.ST_UID so that when a user selects the name of a state from the State box the appropriate ST_UID populates the label, (i.e, California has an ST_UID = 5).

The problem is when a state is selected, I only want the Counties for that state to appear in the County box, i.e, COUNTY.ST_UID = 5 if California is the selected state.

I then tried to convert the value in the st_uid label to an integer:

CODE:

This is what I last tried when again using the Table Adapter Configuration Wizard for the table that populates the County box: SELECT ST_UID, CNTY_NAME FROM COUNTY Where ST_UID = 'StUID' Order By st_uid, cnty_name

What I'm getting is a "Data type mismatch in criteria expression." I'm sure my error is something so simple.

Populate Combobox From Selection Of Another Combobox?

Jan 1, 2012

I currently have a form with two comboxes. The first cbo is being populated with a project number, which is being pulled from the first column of a spreadsheet. I now want the second cbo to read the first cbo and then find that project number on the spreadsheet; when it finds that project number, I then need it to copy data from the row the project number is on. I have converted to vb from vba. Below is the code I used in vba (which obviously does not work). I only need certain cells from the project row.

Dim proj_num, rng As Range
Dim data, i As Long, j As Long

Databound Combobox Selection Retention

Apr 20, 2009

On my form I have three fields and a datagrid view.One field is a combo box.All fields are databound.The datagridview is a detail grid, bound in the "normal" way. Scrolling through records, etc., all work fine.What doesn't work is when a selection is made using the combo box.The underlying table has a self-join of one-to-many: ParentID, ChildID. ChildID is the main ID for the underlying table.Children may have a parent This is just by way of example.So, the combo box's Value is bound to ChildID, and the SelectedValue is bound to the ParentID.On the form one chooses the Parent with this combo box.When I test this arrangement, I select a Parent, then click Save (using the default toolbar actions). However, the combobox seems to "reset" the selection to the first in the list.
