When I check one or more checkboxes then loop through to find which ones were checked if I didnt move the selected cell before clicking go it will not detect the last checkbox checked. However if I change selection it does. Problem is I dont want to change selection, I tried unsBelow is the code I'm using to find which checkbox is checked. This will msgbox me the text in the second column of all the rows checked except the last one I checked

this is the wrong forum because I am quite new to this :S and I am actually unsure what this fits under. I am using Visual Studio 2008 windows form in .vb so I am taking a guess at it being Visual Basic 6.0Well the question is this. On a form I have 3 Datagrids. The first one shows information about a case including client name and ID. The second shows a table that contains all the jobs registered to the company by the clients. lient can have up to 8 Jobs. The third is a list of all case numbers that clients have

on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

I've created a Datagridview bound to a Datatable. This Datatable is updated by a event to reflect statistical information as it changes (sub second resolution). I have a checkbox to determine if a row is available for other functions and can be toggled on and off normally if my eventhandler is not receiving my updates.
If my bound Datatable is changed, the checkbox returns to its previous state as soon as the cursor or focus leaves the checkbox glyph (not the cell).
How do I toggle the checkboxes without them reseting without disconnecting my eventhandler?

I've got a simple Visual Basic 2008 Express Edition form which looks like this:[link Screenshot of simple form][1]I need some help with a skeleton script, which checks to see if each checkbox is checked or not. I've got a set of Word templates which all contain a macro.And I want to run the macro of each template, if the template exists.[code] know this pseudocode isn't correct at all, because I'm kind of a beginner, and designer over a programmer. But I've just started learning and I know this is pretty basic.it's just getting an overview of the logics in programming. And I think that getting to learn how to do this will help me with other things as well.

I am using a BindingSource to fill all the textboxes on my form. It is working for all the textboxes but for some reason it is not working for my check boxes. The value from the database is a boolean and I am setting the property like this.
SG.IsBifocal = CType(.Item(CN_IsBifocal), Boolean)
Is there anything special that needs to be done to bind to a check box?

I have a form that creates a row of checkboxes depending on the type of analysis the user wants to perform on the incoming file. I need to be able to determine if the checkbox is "checked" but I don't know how to do that when the controls are created at runtime.So right now I have a loop going through all the controls on the form and selecting the appropriate case: for instance chkbox1, combobox1, etc. Now I can access the values of the control by using Me.Controls.Item(chkbox1) but after that the only thing resemebling checked is .Text which wouldn't be accurate. how do you workaround the .Checked property of a checkbox when it is created at runtime?

What would be the syntax to check inside a visual basic form panel for checkboxes and find which are checked? I understand how I Could use a for loop and an if statement, but I'm confused as to the syntax to check for each checkbox. for example:
Dim i As Integer
For i = 1 To 10
'Here is where my code would go.
'I could have ten checkboxes named in sequence (cb1, cb2, etc),
'but how could I put i inside the name to test each checkbox?
