1 Variable - 2 Formswhat I am reading in the helps. Its gotta be so simple but I just cant figure out what im reading. ( vb 2003 ) Lets say i have Form1 and Form2. Each form is blank. ( no text boxes or anything ) Very Simple Example: ( i just need a start and then i can modify it and learn from it to do what i need to do ) On form1_Load 'I have a variable called cHello Dim cHello As String = "Hello World" ' I call form two. Dim frmSecondForm As Form = New Form2() frmSecondForm .ShowDialog() EndSub On form 2's load, I want to MsgBox( cHello ,MsgBoxStyle.OKOnly, "Title Of Box") close() EndSub How do I Properly pass the variable to form2 ? Thanks, Miro Miro napisal(a):

So if want access objects property, method... you have to specify this object like it was done here: Form1._text If you have problems working with multiple forms read this articles: http://www.devcity.net/Articles/94/multipleforms.aspx http://www.devcity.net/Articles/100/multipleforms2.aspx http://www.devcity.net/Articles/102/multipleforms3.aspx http://www.devcity.net/Articles/117/1/multipleforms4.aspx And by the way, msgbox() is clasic vb function. In vb.net it is recommended to use: messagebox.show(text, caption, buttons, icon) Hope this helps. Regardsm sweet_dreams pass it on Form2 thru constructor parameter wen calling form2
pseudo code: dim myString as string="hello world" dim f2 as new form2(myString) ----- now in form 2 dim myvar as string sub new (byval x as string) myvar=x end sub now on load event put the msgbox n display myvar you could also make one variable Public so everything can see it, (VB 2005) ex:
Public str As String Private Sub Form1_Load(..) Dim frm As New Form2 str = "Hello" frm.Show() End Sub '''form 2 Private Sub Form2_Load(...) me.text = My.Forms.Form1.str end Sub '''''''''''''''''''''''' or you could make the variable reflect a property on form1 just my 2 cents, hope this helps -- -iwdu15 Thank you all,
I was soo close.

It didnt work, I had my variable declared as Public myText As String but it didnt recognize it on the second form until I put Public Shared myText as String Is this a vb 2005 to vb 2003 difference or did you just miss that in the example ? Thank you for your example though... the links on the bottom, I actually read the night before, but in my case I was always missing the "shared" property.

But using Shared is also good. So use Shared. Regards, sweet_dreams Im 2003 and It does not recognize the formname.value if the "Shared"
property is not there. So that looks like it is a difference in 2k3 and 2k5 version. Thanks Sweet_Dreams ps. "napisal(a)" is that Czech or Slovak ? - "Miro Wrote" :) thanks agian.

My god, it's like the blind leading the blind.. Lets set things straight. First, The new form instantiation shortcuts in 05 suck ass. M$: Take this crap OUT. M$ made it possible to reference a "default instance" of a form without explicitly instantiating it, in 2005. This is more VB6 style than .NET, and it is misleading and confusing to newbies. TAKE IT OUT. So.. While you can simply do Form2.Show, and Form1.SomeField in 05, in 03 you must have explicit instances of Form1 and Form2 (you do in 05 also, but the language hides the details from you). This is also why Miro noticed that adding the Shared keyword to the field made things work. Ya'll need to read up on variable scope. Proper way to do this: in Form2.vb: Add a private field (sSomeText), and a public property (SomeText) in Form1.vb: Add to the Load event handler: Dim tForm as Form2 = New Form2 tForm.SomeText = "blah blah" tForm.Show in Form2.vb: Add to Load event handler: msgbox(me.SomeText) Also, as stated earlier, you could overload the ctor for Form2 and pass in the text there.

- If i understand your example. The proplem is using a straight variable that I run some calculations on and have random outcom and then pass it to another form. Everywhere on the net they use a textbox.text example... nowhere do they have a Dim myVariable as String = "X" and now pass that between forms. M.

Variable, Property.. whatever.. it doesnt matter.. How about this example: on form2 create a new sub: Public Sub MyGodItsHideous(byval tCreatureName as string) msgbox("When " & tCreatureName & " was a child we had to hang a chunk of meat around its neck just to get the dog to play with it!") End Sub on Form1: Dim tForm as Form2 = New Form2 tForm.MyGodItsHideous("Jennifer Lopez") The point is, a form is just like any other class. -Boo Show quoteHide quote > The problem wasnt with a text box > - If i understand your example. > The proplem is using a straight variable that I run some calculations > on and > have random outcom and then pass it to another form. > Everywhere on the net they use a textbox.text example... > nowhere do they have a Dim myVariable as String = "X" and now pass > that between forms. > > M. > > "GhostInAK" <ghosti***@gmail.com> wrote in message > news:c71747b42b0688c8856ab6d26c6d@news.microsoft.com... > >> Hello Miro, >> >> My god, it's like the blind leading the blind..
