In Menu "Project Options"->"Version Info" you are able to specify a version of your program.
Is it possible to show this version to the user in runtime of my program? (Maybe in a wxStaticText field?)

Yes, although not by using wxWidgets. This is a platform issue as the version info is placed in the resources of your app. Only on Windows you can use these.
Have a look here for a nice class that can help you to get the info:
http://www.codeguru.com/cpp/misc/misc/v ... .php/c319/
It's MFC but should be easily portable. If you have problems with that, say so and I'll see what I can do and place it in the code dump.

Looks nice, but I DO HAVE PROBLEMS with that.
My compiler can not find the stdafx.h. I had to download it, but I am not sure if it fits into wxDevCPP?
Then I must change all the CString into wxString, right?
Then it will not find the ASSERT function. Do I have to replace this with a wxDevCPP function? Which one, what should this function do?

And then how to call it?
I tried something like

Code: Select all

    FileVersion *FCCM = new FileVersion;
    WxEdit1->SetValue(FCCM.GetFileVersion());

I think I have to open the module first. But what is the module? If it is the complete filename, how to get it? (User can change it...)

So many problems, sorry...

there is a header file which contains the informations about the version.
<projectname>_private.h
include it to your project and compile it, then you can use the version information.

Nope, it doesn't. VC/MFC only stuff you don't need and want

Tobi wrote:Then I must change all the CString into wxString, right?

In a way, yes. You'd have to change some other things too.

Tobi wrote:Then it will not find the ASSERT function. Do I have to replace this with a wxDevCPP function? Which one, what should this function do?

wxASSERT is the way to go

Code: Select all

char szExeName[MAX_PATH];
GetModuleFileName(NULL, szExeName, sizeof (szExeName));

This would give you the name of the current running module.

Anyway, I created a small converted version called wxFileVersion.
I tested it with VC and it works. I suppose it should work with gcc, too. Note that when compiling you'll need to add version.lib ( libversion.a, or -lversion for gcc) in the linker list.

wxFileVersion.h

Hi HeReSY,

thats a very simple and working solution. So much thanks to you. This forum is great!

THANKS!!!!!

And of course a big thanks to upCASE, who helps with his very descriptive answers to understand the background much better. Sorry you had so much work, although there was an easy way. THANKS.

Found this code very helpful, but had to adapt it a bit for wxWidgets 3.0.2 & Unicode

wxFileVersion.h stays the same.

Great, that you post this piece of code that helps to retrieve all the version information!

It maybe mentioned additionally, that you have to link with "version.lib".
