How Do I Display Application's Version Info?

[James Graham]

In VB6, it was easy to display the app's version information (major, minor,
revision) in a textbox or a label.

All I had to do (if I recall correctly) is the following:

Let's say I want to display major version info in a label called "label1":

label1.caption=app.major

Likewise, I could concatenate the version info strings (major, minor, etc)
into one string and display it just as easily.

I have yet to figure out how to do this with VB.NET.

Suppose I have a label called "lblVersion".

How would I display all of the available application version information
within this label?

All I want is a line of text displayed on my app's form that looks similar
to the following:

"Version 1.0.0.1"

Thanks,
Jim Graham

lblVersion.Text = "Version " & Application.ProductVersion

Should do the trick.. . .

Jacob, thanks for the reply.

Actually, I tried this but it causes the Microsoft Development Environment
to popup a message box stating the following:

"The following exception has occurred:
BadImageFormatException: The format of the file 'devenv.exe' is invalid."

In fact, a reference to ANY "Application.xxxxxxxxx" causes this.

Thanks,
Jim Graham

James-

I do believe that this error is indicative of a bad install.

Unless you are doing something with a Managed C++ app?

Not that I can tell.
I've installed vs.net on a different machine just to see if there was a "bad
install". I get the same symptoms.

However, I've observed some new behavior which I (being new to VB.net) certainly
cannot explain.

The code:
lblVersion.text=Application.ProductVersion

actually works, reporting the information requested and with no errors.

However, this only true for a project developed using the "Windows Application"
template. What I'm developing is a project using the "Windows Control Library"
template. THIS is where the problem occurs.

I'm developing a control to display a virtual "LED" indicator. The control
has a number of custom properties defined by me. One of those properties
is to display an "About" window. It is on this "About" window from that
I'm trying to display the version of the usercontrol.

To test, I have brought in a "test" form on which I can place my new control.
I drop a control onto the form, then I double-click on the control's "About"
property and up pops my "About" window, but shortly prior to that, I get
the devenv.exe error.

I mentioned earlier that the "Application.ProductVersion" works in a normal
windows application form. However, it bombs if I try to place my custom
control on the application's main form, but textbox, label and other Microsoft
controls seem to be happy when I invoke the above. This tells me it's something
I'm doing wrong with my custom control...at design-time. Maybe it's simple.
Maybe I'm not supposed to use the "Application.ProductVersion" call from
a usercontrol????

Thanks,
Jim Graham

James-

Okay, that helps narrow down the problem a bit. The Application class is
really only applicable in a situation where a MessageLoop is being created.
This occurs with Windows Applications, not Class/Control libraries or
UserControls. UserControls (Control libraries) versioning info exists in
the AssemblyInfo.vb file. I am not sure how to retreive this information at
runtime. Perhaps someone else can chime in with their expertise.

AssemblyVersionAttribute is a pseudo-custom attribute that ends up
being part of the assembly name. It can be retrieved with

System.Reflection.Assembly.GetExecutingAssembly().GetName().Version

Other Assembly* attributes can be retrieved with

System.Reflection.Assembly.GetExecutingAssembly().GetCustomAttributes()

Mattias,
Thank you for your help.

I've got it all working now. I had to massage your suggestion to get it
to work. In particular, I had to be more explicit in terms of getting the
version information.

In particular, I had to do the following....
----------------------
Dim strMajorVersion, strMinorVersion, strBuildVersion, strRevisionVersion_
As String

strMajorVersion = System.Reflection.Assembly.GetExecutingAssembly_().GetName().Version.Major()
strMinorVersion = System.Reflection.Assembly.GetExecutingAssembly_().GetName().Version.Minor()
strBuildVersion = System.Reflection.Assembly.GetExecutingAssembly_().GetName().Version.Build()
strRevisionVersion=System.Reflection.Assembly.GetExecutingAssembly_().GetName().Version.Re vision()

lblVersion.Text = "Version - " & strMajorVersion & "." & strMinorVersion_
& "." & strBuildVersion & "." & strRevisionVersion

--------------------------------------------------
Again, I wish to thank both you and Jacob for your help!

Regards,
Jim Graham

I believe you can shorten that to

lblVersion.Text = "Version - " & _

System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString()
