Dim testCBX As Excel.CheckBox
testCBX = wb.Worksheets(1).checkboxes("CheckBox123")
I have created a spreadsheet with multiple worksheets. I would like, after checking one of several checkboxes (which I could change to another button I really dont care) taking me to another of the worksheets within the same file. What I don't want to happen is the original sheet to disapear so that I can't return to it via the tab at the bottom of the page if I need to.

Interesting problem. I have a datagrid with several columns which are bound to an Access database. Here's the situation...I'm concerned with the 3rd column.This is what I'd like to happen... when the 3rd column(is a checkbox) is checked then column 4(TIME_USER) would be populated with the current time
Basically, this application is meant to keep track of tasks that the user has to do at a certain time of the day. When the user checks the checkbox it would record the time in the database for that task as to when they did it. I found some code from a forum that i changed to fit my needs, but it's not working.

I have a pre-existing database which I am coding to, so I can't change the data stored in the SQL-Server 2005 database. My application uses the DataGridView to maintain the data. There is a yes/no field that I would like to bind a checkbox to. The field is a character field in the database, and holds either Y or N. So, here's the question. I know how to set the column to be a checkbox, I think, but I don't know how to map it so that it reads/stores a "Y" value as checked and a "N" value as unchecked.
View 1 Repliesthis gonna sound like a really basic problem but would some1 be able to tell how me to get a checkbox selection to be displayed as a peice of a text in a listbox or a text box.
View 13 RepliesI am trying to enable/disable a checkbox depending on whether or not a match is found on the checkbox name and a list of controls. When I step through the code and pass the line "ChkBox.Enabled = pbEnable", the Enabled value does not change. In this case the state before the change is False. pbEnable is True.[code]

i have a checkbox bound to a column with datatype character to my database... the column uses values Y and N.also, just like to add that i have tried changing the column into character of 5 byte so that it can hold the values "True" and "False" when the property bound is the property Checked. this works okay but there are some columns that doesn't use True and False like in my statement above.is there a way that i can set my checkbox to checked when the column value it is bound to is Y and vice versa.. i noticed that in the checkbox inside a datagridview has the properties TrueValue and FalseValue but i dont see this anywhere in the checkbox not in the datagridview.

I have a Infragistics ultragrid with a checkbox column (no binding on the checkbox column) need the user to only have one check box selected at a time. If a checkbox is checked and the user checks another row I need the first checkbox to uncheck. I am new to infragistic controls, so I apologize if this is a simple property that I have not found. But I have searched the forum and KB to no avail. Do I have to rip through the rows and uncheck all rows but the active one?
View 1 RepliesThe GridView is bound to an Access Table, but I want to update the checkbox using the asp:ButtonField. The best I've been able to do is replace the checkbox with a string value. Below is the code I have now:

I have a checkbox in my application,when the checkbox is checked then i want to fetch the data from the database and add it to the dropdownlist of the combobox.Again when the checkbox is unchecked then i want to ramove all the data from the dropdownlist of the combobox.
I did this
Private Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
If CheckBox1.Checked = True Then
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=Etech.mdb")

When the checkbox is checked then the data is added from the database to the dropdownlist of the combobox but when i uncheck it then the data is not removed from the dropdownlist of the combobox. In the above code i think i need to add an else condition to remove the data from the dropdownlist of the combobox and make it empty when the checkbox is unchecked.......but i cant give the proper else condition in the above code.
I have the following update command which needs to be amended, I want before the query to check if chkactive checkbox is checked or Not, if checked then True value to be added to the tblProjects otherwise if unchecked False to be added.

I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
I've got a form with parent-child setup. The parent displays name and other demographic info.The child displays multiple addresses, one row at a time. There can only be one primary address for a name and this is designated by a checkbox at the top of the child form.If the user wants to change the primary address to another address,then they find the other address and click on the checkbox.The form checks the other addresses and if one is found that is designated as primary,the user is warned that one already exists and prompts them to change it.
So for example, a name has 2 addresses, the 2nd being the primary address.The user wants to change the 1st address to be primary.They click on the Primary Address checkbox for the 1st address.A warning displays that there is already an address listed as primary.The user then answers the prompt to change the 1st address to the primary address.The checkbox for the 2nd address will be unchecked and the checkbox will be checked for the 1st address.My problem is getting the checkbox unchecked for the 2nd address.If I close the form and reopen, then the checkbox is unchecked.How do I refresh the checkbox for the 2nd address?Here is the code I'm using to find if an address has already been marked as primary:[code]......
