Values in other forms?

Hello,

   I have a program that is not MDI.  I have two forms one called frmMain and one called frmBrowser.  For some reason I can't access values in frmMain from frmBrowser.  For example, on frmMain there are 3 text boxes and 1 list box.  If I try to access the values of these from frmBrowser it doesn't work.  For example, frmMain.txtUsername is blank when I use it in frmBrowser.  If I select the first item in the listbox, frmMain.lstItems.selected(0) is false.  But the weird thing is I can access the properties.  I can get the values like frmMain.txtUsername.height and frmMain.lstItems.listcount.  Whats going on here, do the forms need to be MDI childs to be able to access each others values?

They don't need to be MDI children, but they do need to be loaded at the same time. Otherwise attempting to get the value of a control on another form will Load the other form implicitly (may not show it unless you specify this) and you will then get the default value of each control.

I have tried a simple test of this myself and it seems to work fine.  Is there any other info you could provide?

You do not need to use MDI to do this.  It should work fine.

I assume both of your forms are loaded?

Yes, frmMain loads first, then frmMain calls frmBrowser and frmBrowser is trying to get data from frmMain.

Ok,

I just did a simple test by creating a new project and it works fine.  The application I'm having trouble with was created with the wizard.  Could this have anything to do with it?

if you really can't make it work you can create a couple of public variables in a module and load the values into those before you show the browser form.

You can then reference the global variables on the browser form, rather than referencing the objects on the main form.

It's a work-around, not a solution, and I have no idea why that would be happening...

did you unLoad the frmMain when opening frmBrowser?
if so, change the statement "Unload Me" to "Me.Hide".
also, use "frmMain.txtUsername.Text" (notice the ".Text").

if it still cannot work, declare a public variable in frmMain. (this is what ebosscher suggest)

//put this in Declaration section
Public UserName as String

//put this under subroutine that open your frmBrowser
UserName=txtUserName.Text
frmBrowser.Show

//use the UserName, instead of txtUserName
//in your frmBrowser, eg.
Msgbox frmMain.UserName
