Is their a possibility to call SDK functions from TestStand directly?

[Brosig]

Hello!

I want to call a function from the Windows SDK.

Is this possible?

Brosig,

the SDK is nothing but a collection of windows-DLLs. so you can call the SDK directly via the DLL-adapter. but take care because the SDK-DLLs do not contain infos on the prototypes on their own. so you got to build your own prototypes of the functions on your own.

Hello,

I tried calling a SDK function via the dll-adapter with added prototype. But when I run this step, it stops with a Message "... could not find pdb-File...". I think PDB files can be created by compiling a Visual Studio Project. But I can not create a pdb-File for SDK dll. So I thought it is only possible to call function from a dll which I create on myself. Is there a workaround?

What function was you trying to call?

and to complete rays question: which DLL do you exactly use?

I tried to call GetPrivateProfileStringA() from kernel32.dll.

Brosig,

sadly i dont know what the error with the pdb-file could be. but as far as i see from the description to the function found here, there should be no such dependency.
please take a look into the "requirements"-section of the link. it seems that kernel32.dll is sufficient for usage of the function. and for myself, i never had such problems when using the kernel32.dll.....
one problem could be the type of the parameter you are using. i know that there are sometimes odd issues on SDK when the parameters do not fit exactly the needed type.  so make sure that all strings are null-terminated and the buffers you pass are preallocated!

Hi,

I think there was an example on the NI web site. If not I might still have the example somewhere.

Hello all together and a happy new year!

I found the reason for the error/warning message.

All the time I was testing the sequence with the function call step with F8 (Step Into).

When I run the sequence normal it runs fine.

A typical Userfailure.

Thanks for all your responses.
