all transactions, and issue Btrieve operation 25, using the BTRV

1017: The Btrieve Requester is unable to find the

resource file WBTRVRES.DLL

WBTRCALL.DLL returns this status code when it cannot find the

resource file WBTRVRES.DLL. Place the WBTRVRES.DLL file in the

same directory as the WBTRCALL.DLL file.

1018: The application attempted to call the MicroKernel

from a Btrieve callback function

The Windows MicroKernel does not allow a task to call the

MicroKernel from a Btrieve callback function. You can only use the

callback function with Btrieve for Windows.

1019: The MicroKernel cancelled the current Btrieve

operation at the request of the application’s Btrieve

callback function

The MicroKernel callback function of an application returned a

nonzero value, indicating that the application wants to terminate the

current operation immediately. When the MicroKernel receives such

a cancellation request, it attempts to terminate the currently

executing operation and ceases to call the callback function for the

duration of that operation. The MicroKernel may be unable to

cancel the operation. However, if successful in doing so, the

MicroKernel returns this status code.

1020: Btrieve Requester Interface communications error

The MicroKernel loader and requester Interface returns this status

code when it cannot send a message to the MicroKernel. This occurs

when Windows is shutting down or when you terminate the

MicroKernel using Ctrl+Alt+Delete. This is an informational status

code only. No action is required. Your application continues the

shutdown process. You also receive this status code when running an

application that prevents Windows from processing messages.
