Can't PInvoke function "OpenStore" in WinCE 5.0

Hi All!
I've tried to PInvoke function "OpenStore", "DismountStore" and so on, but unfortunately I've got message like this "Can't find PInvoke DLL 'storeapi'."

code snippet

C#

[DllImport("storeapi")]
        public static extern IntPtr OpenStore(string szDeviceName);

Could someone help me?

I closed this question!!!
Reason:
I made wrapper around storeapi.lib through C++. It compiles great! But if I invoke functions from there I get error 120!
It means "This function is not valid on this platform."

What you need to do is create an unmanaged DLL (using C++) by linking the storeapi.lib file to it. At that point, you can PInvoke to your newly created DLL. I believe it's the best/only way.

Thanks for your response

Summary:
He cannot find the DLL or required API in this DLL.
After finding LIB asks question if he can convert it to DLL (which is impossible, and the lib is just a link to DLL). After I answered, he added a separate question about conversion of LIB to DLL.
I think my advice is ignored.

Solution 1

Must be "storeapi.dll" or "coredll.dll".

OP commented:

It doesn't matter.
I can't find this file in Windows Mobile.

Sergey Alexandrovich Kryukov 13-Mar-11 22:10pm

1) It does matter.
2) Answer updated: could be coredll.dll, depending on you version.
3) Before doing P/Invoke, run dump of dll and see what exactly exported (use "dumpbin.exe", for example)

I tried to P/Invoke with storeapi.dll but it doesn't work still :(. I think My WinCE doesn't have storeapi.dll. I need this file. Where can I get it?

Sergey Alexandrovich Kryukov 13-Mar-11 23:53pm

You already told that. What do you mean "I think"? You could perform a global search. I don't know... How about "codedll.dll"? You suppose to have "storeapi.lib". Do you have it? You can dump it as well. You can also try native code, just to see if the DLL is there and find out which dll.

I can't find storeapi.dll anywhere. I tried to find this file in google but didn't have any result.

Sergey Alexandrovich Kryukov 14-Mar-11 1:45am

Did you pay attention to what I suggested?!! How about coredll.dll?!!!
--SA

_Ares!!! 14-Mar-11 1:49am

I downloaded storeapi.lib from this link :

Sergey Alexandrovich Kryukov 14-Mar-11 2:09am

Did it work? Could be from different OS version, so...

Can't find entry point in coredll.dll error if I use coredll.dll

Sergey Alexandrovich Kryukov 14-Mar-11 2:07am

Did you use dumpbin?
--SA

_Ares!!! 14-Mar-11 2:21am

Yes, I did! This lib file contains all necessary functions (I mean storeapi.lib)... But unfortunately [DllImport("MyTest\\storeapi.lib")] doesn't find this lib file. I don't understand why?

Sergey Alexandrovich Kryukov 14-Mar-11 2:28am

This is because DLLImport does not work with lib files. Did you find out a DLL?
--SA

_Ares!!! 14-Mar-11 2:35am

I, didn't! I'll try to find it.

_Ares!!! 14-Mar-11 2:36am

Can I convert Lib into DLL?

Sergey Alexandrovich Kryukov 14-Mar-11 2:41am

Of course not. This kind of lib is most likely a binding lib to dll. But! You should locate the name of DLL in the lib.

5 for answer and effort!

Sergey Alexandrovich Kryukov 14-Mar-11 3:32am

Or, it was you! Thank you very much. Unfortunately, OP is still doing something.

_Ares!!! 14-Mar-11 3:07am

Bad news. Google keeps silence when I looking for storeapi.dll.

Sergey Alexandrovich Kryukov 14-Mar-11 3:27am

Don't look in Google, look in LIB file. I told you twice!
--SA

_Ares!!! 14-Mar-11 4:17am

And what should I see there? Sorry, but I don't understand you :(

You have given the word patience a new meaning SA.
Congratulations and my 5!

Sergey Alexandrovich Kryukov 14-Mar-11 13:07pm

Thank you.

Sergey Alexandrovich Kryukov 14-Mar-11 13:07pm

Read above. What exactly don't you understand?
Read LIB through dumpbin and find which DLL it requires. Use that DLL.
You won't be able to convert LIB to DLL just because your LIB is for linking the DLL.

Amazing effort - my 5

Thank you, but I don't know is if the problem is resolved, so much of confusion..
