Setup.dll => too big, why?

[James Hetfield]

Hello

I'm new to C++.

I am trying to create a setup.dll in VS 2005. The samples in the SDK didnt
work for me:
=> removed the CAB-Project in it, then tried to build the DLL, I got:
1>------ Skipped Build: Project: SetupDLL ------
1>
========== Build: 0 succeeded or up-to-date, 0 failed, 1 skipped ==========

I dont know why, tried from Smartphone WM 5 and PPC WM 5... the same...

So I have created an own project:

1. New Project = > Visual C++ => Smart Device => MFC Smart Device DLL
2. then I proceed like this here:
http://www.pocketpcdn.com/articles/setupdll.html
3. I added in the codeINSTALL_EXIT-Section:
between AFX_MANAGE_STATE(AfxGetStaticModuleState());
and
return codeINSTALL_EXIT_DONE;
the following:
PROCESS_INFORMATION pi = {0};
CreateProcess(TEXT("\\My Documents\\myapp.exe"), TEXT(""), NULL, NULL,
NULL, 0, NULL, NULL, NULL, &pi);

This is working! But: The DLL is 361KB big (!)

Why is this? What have I done wrong?

Thanks

James

The last is likely becuae it's bringing in MFC, which you have no need for -
don't use it.

Hi James,

As Chris mentioned, the filesize got big coz the project uses MFC. If you
statically link MFC it might even be bigger. I found another step by step
example for creating a CE Setup DLL that just uses pure Win32

Here's the link:

Hi

If I turn off Static Linked (set to dynamic), I can build it. but when I
create the cab and install it, it just says "cannot install"....

If I have static linked, it is working (but is big)

I will try your link although it seems to be quite a lot to do for a total
new-to-C++...

Thanks

Hi Chris

Thanks, but how can I turn it off?

I tried to using dynamic link to it, it is building well, but when I then
install my cab, it just says taht installation failed... if I have static
link, then it is working...

Thanks

I have now downloaded eVC++ 4 (+SP4), and created a dll exactly as described
in the link
http://www.pocketpcdn.com/articles/setupdll.html

It did build, only 7.5KB, but when I am trying to install it, it failes...
I'm quite sure that my cab settings are ok, because if I use the big file
with MFC, then it is working...

Now I want use this library in C#, but when I invoke this function

[DllImport("LibWrapper.dll")]
public static extern int summ(int i , int b);
....
public DllWrapper()
{
....
int result =summ(1, 2);
....
}

The emulator throw this exception :

System.MissingMethodException was unhandled
Message="Can't find PInvoke DLL 'LibWrapper.dll'."
StackTrace:

at MyPrimaApp.Program.Main()

I have tryed to copy the LiWrapper.dll everywhere in the project, but no change.


Please Help me.

Are you sure that the DLL is copied to the device?

Hi James,

My guess is that you are still starting with an MFC Project.

If you are starting out with an MFC Project, then your installer will
require MFC.

If MFC is included on the device you are trying to install on, then you can
use the smaller build (doesn't wrap MFC into the file). Since your
executable is failing, I would guess your device does not include MFC. So,
to take advantage of MFC, you will need to include it.

If you do not want to use MFC, you are going to have to create a project
*without* MFC. You said you are new to C++, so you may not want to go this
route because there will be several other steps to create your program when
you start with a "non-MFC" project.

Hope this helps,
~Joe
