I'm currently writing a program in WDM18 for a Windows CE 6.0 device.
I ran into some problems using the built in WDM camera control, so I
have to use the API's provided on the device to take pictures.

I can successfully call the necessary API's using the API Description
variable type without any problems.

However I'm a little confused on how to access one of the provided APIs
to set the path for the image it saves.

Here is the API as described in the device documentation:

SetStillCaptureState:
Purpose: Sets how to take pictures.
Syntax: DWORD SetStillCaptureState (PICSTATE *picInfo);
Parameters: picInfo
[in] Pointer to structure PICSTATE where the
settings are stored.
Return Value: If successful, it returns 0. Otherwise it returns a
non-zero value to indicate a specific error:

The PICSTATE structure is described as follows:
typedef struct
{
INT AutoExposure;
INT AutoWhiteBalance;
INT ImageFormat;
WCHAR lpPathName[500];
INT PathSize;
WCHAR lpFileName[500];
INT FileSize;
} PICSTATE, *PPICSTATE;


I'm unsure how to access this in WinDev Mobile. Any suggestions would be
greatly appreciated.


As a reference, here is one of the other functions I am able to call
successfully.

StartStillCapture:
Purpose: Starts taking pictures.
Syntax: DWORD StartStillCapture (INT playSound);
Parameters: playSound
[in] Integer variable
0 = No sound
1 = Sound to notice of a picture taken.
Return Value: If successful, it returns 0. Otherwise, it returns a
non-zero value to indicate a specific error.

And the code I use to call StartStillCapture:


I can also provide the PDF documentation for the unit if it would help.

Many thanks for any assistance.

Ok, so I need to use the API() function instead of the API Description
variable type?

Thanks I'll give it a shot.

Thank you for your help Fabrice.

I'm getting close to getting it to work correctly using the API() function.

Out of curiosity, if I wanted to use the API Description Variable type,
what would you set the Parameter[x]..Type to in order to pass it a
structure?
From what I can see, the documentation only lists the following
variable types.
apiBoolean
apiBuffer
apiCharacter
apiAnsiCharacter
apiUnicodeCharacter
apiString
apiAnsiString
apiUnicodeString
apiInt_4
apiInt_8
apiSystemInt
apiReal_4
apiReal_8
