Major unsolvable problem

[Winston]

wow its rite!!!! thats how i wanted it

 

 

thx

 

 

im not getting how u get the _parent thing and _selected font tow rokwhere u declare it?

[Cywizz]

look under the region "Class Variables". I've declared it there.

[Winston]

hmm i copied the class variables in

and the little code for the apply button in my project

it aint working too well

:S

i get object reference error

[Cywizz]

I assume you're getting the error on the click event of the apply button..... Have you created the new constructer with the parent reference, and did you set the passed in form to the local _parent variable?

Try to understand what I did, rather than copying the code....Once you understand these concepts(constructors/overloading/object refs) you will find it a lot of fun, and you never will want to go back to vb6 :o

[Winston]

i still am not understanding it too well read it over and over

 

tried to replicate it first to get it working

 

didnt work

 

copied region constructor

 

and class variables and also bounded it by the region events

[Cywizz]

You cant just copy the example code and expect it to work. Understand my example in context of yours, and apply the best solution based on that.

 

btw, you can't just copy the events, because I'm using my own control names... It looks like the events isn't firing... try to step through your code

[Winston]

im confused in terms of regions and stuff..

[Cywizz]

Ok, forget about regions... regions are just a way of grouping your code (part of documentation...)

Step through your code... that is the ONLY way you can determine where and what the problem is...

[Winston]

i see zero errors wrong with my code

 

 

 

stepped through it all

went through the windows generated form code

 

 

 

this is the code for the font form

 

 

#Region "Constructor"
   Public Sub New(ByVal parent As Form)
       'fire other constructor
       Me.New()
       'set the module level variable
       _parent = parent
   End Sub

#End Region
#Region "Class Variables"

   Private _parent As Form
   Private _selectedFont As Font

#End Region

#Region "Events"
   Private Sub btnCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCancel.Click

       Me.Close()

   End Sub

   Private Sub btnBrowse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBrowse.Click


       fntAppBase.ShowDialog()
       _selectedFont = fntAppBase.Font
       lblPreviewBox.Font = _selectedFont
       txtFontSel.Text = _selectedFont.Name


       btnApply.Enabled = True


   End Sub

   Private Sub btnApply_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnApply.Click


       _parent.Font = _selectedFont



   End Sub

   Private Sub frmAppBaseFont_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

   End Sub

   Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
       _parent.Font = _selectedFont
       Me.Close()
   End Sub
#End Region

End Class

:S

i get object reference error

so where does the error occur? The only problem I see is when the cancel button was clicked on the fontdialogbox (_selectedFont will be nothing)

[Winston]

it occurs wen i click on the apply button

 

 

 

object reference not set to an instance of an object

[Winston]

ok i finally got it

 

it was all the main forms fault

 

 

the dim frmfnt as new frmfont ()

 

 

i missed the (me) out

 

 

wat does that do? the me

[Cywizz]

It passes the mainforms reference (me) into the fontform (via the constructor). This reference is then set to the variable: _parent.

Read up on constructors and overloading, it will explain it better.

Cheers!

[Winston]

thanks i got most of the box underway one last error free thing i need to do is

checking the cancel button

 

 

say the font form is loaded

 

and the user opens the font dialog they selected a font and then clicked cancel and clicked on OK it applied still

 

:S....

 

 

how do i control the cancel button so it does nothing

[Cywizz]

I'm going to draw the line here... this problem should be solved by even the novice of vb6 developers.

I do suggest, as divil did, to get yourselve a proper vb.net book. I used, and recommend, Professional VB.NET - ISBN 1-861004-97-4

Cheers!
