.NET Newbe needs help

[RudyL]

Ok.. I am completely new to .NET (but have been doing VBx for years now) so I have what might be a very basic question..

I have created a "Splash Form" that resembles the splash form in VB6. My question is how and where would I put code to populate the labels? I want to do it in the form load event but I do not see one. Is there even an array like in vb6 such as App.Version type of thing?

Thanks,
Rudy

Why do you want to populate the labels at run time? Just change them at design time in the form designer...

and I'm not sure what you're on about with App.Version thing... and there is a load on each form. Don't know why you can't see it

[Mike Hildner]

You can get the version like this:

MessageBox.Show(Application.ProductVersion)

[RudyL]

In Vb I could make a lable reflect the build version of the code by saying:

label.caption = App.Version

By doing this I do not have to remember to change the lable every time I build the program..

Make sense?

[Mike Hildner]

Oh, and if you can't see the Form_Load event, you can get to it in a couple different ways. One, just double click on your form and the IDE will create the method for you and bring you there. Or, if you're already in the code, the drop down box on top and to the left, click that and choose (Form1 Events) - or whatever your form name is, then on the right drop down, choose the Load method.

I think that is exactly what I was looking for.

Two quextions though..

1. How would code in VB6

form1.lblcaption.caption = App.Major & "." & App.Minor & "." & App.Revision

Translate to .NET?
I got part of it:

{Needs the form name here I think} lblVersion.Text = Application.ProductVersion

The other question is that the version displays as 1.0.1671.23823 - However I have not built it that many time.. I don't think so anyways..

sorry, i didn't realise u wanted that

i thought u meant static text, i was wondering why you would want to do it at run time...

Thanks for that, I finally found it. I was in the code for a fram (Group Box).. ooops...

[Mike Hildner]

form1.lblcaption.caption = App.Major & "." & App.Minor & "." & App.Revision

Would be something like

Label1.Text = Application.ProductVersion

I have no idea why the build numbers look like that, never really looked into it. Something to research. FYI check out your AssemblyInfo.vb file if you want to mess with the version. Here's the relevant part:

' Version information for an assembly consists of the following four values:
'
'      Major Version
'      Minor Version 
'      Build Number
'      Revision
'
' You can specify all the values or you can default the Build and Revision Numbers 
' by using the '*' as shown below:
 
<Assembly: AssemblyVersion("1.0.*")>

I usually just change mine to 1.2, 1.3 or 2.0 or whatever.

[RudyL]

Is there no way to access those through the User Interface? Kinda like it is done is VB6 (See attached)..

[Mike Hildner]

Not that I'm aware of, but that doesn't mean much. Also not sure about the auto increment build thing.

About this... You didn't list out the form.. How would I set the label property from another form or module? I need to do something like (vb6) for1.label.caption. However, I can't figure out how to call the [form].what ever...

[Mike Hildner]

If you're doing inside the class (in this case a form) that has the control you want to reference, you don't need to specify the form name, because it's assumed. However you could write it like

Me.Label1.Text = Application.ProductVersion

If you're trying to do it from a different class, then you need a reference to the instance of the class you want to change.

Could you give me an example of this?

Sorry I have so many ?? I feel like I am starting all over again..

In a way you are. It's a different animal, no doubt. But much more fun to play with, IMHO.

Unsolited advice you can choose to ignore - first, try searching around because I know this has been discussed before. Second, make a new thread for a different subject.

That being said, what, exactly do you want to do? Reason I ask is to me that's kind of a general question, but, as you know, there are many way to skin a cat Can you give an overview of the program flow you want to achieve?

Is this what you are looking for?

Yea, I do need to do some more reaserch.. I kind of got off topic here..

I am just making a "First" app. I have not really done anything other than make a form that says Hello before in .NET.. In this particular one I am trying to immitate the Splash form that VB6 supplies as an example since I did not see one in .NET. I thought it would be an easy thing to do and learn..

If I understand this (and I probably don't) I have to inessance create an alias for the form to be accessed out side of the form?


Let me give you a better - simplified example of what I am expecting to be able to do..

(This is in VB6)

' ModMain code
Public Sub Main
 
frmSplash.lblVersion.caption = "Version: " & App.Major & "." & App.Minor & "." & App.Revision ' This is displayed as Version: x.x.x
frmSplash.show
DoEvents
Call Sleep(5000)   ' Wait 5 seconds
DoEvents
Call UnLoad(frmSplash)
DoEvents
 
End Sub
