Change String Mode Function

When the Integration Service runs in Unicode mode, it passes data to the procedure in UCS-2 by default. When it runs in ASCII mode, it passes data in ASCII by default. Use the INFA_CTChangeStringMode() function if you want to change the default string mode for the procedure. When you change the default string mode to MBCS, the Integration Service passes data in the Integration Service code page. Use the INFA_CTSetDataCodePageID() function if you want to change the code page.

When a procedure includes the INFA_CTChangeStringMode() function, the Integration Service changes the string mode for all ports in each Custom transformation that use this particular procedure.

Use the change string mode function in the initialization functions.

Use the following syntax:

INFA_STATUS INFA_CTChangeStringMode(INFA_CT_PROCEDURE_HANDLE procedure, INFA_CTStringMode stringMode);

The following table describes the arguments for this function:

Argument	Datatype	Input/ Output	Description
procedure	INFA_CT_PROCEDURE_HANDLE	Input	Procedure handle name.
stringMode	INFA_CTStringMode	Input	Specifies the string mode that you want the Integration Service to use. Use the following values for the stringMode parameter: eASM_UNICODE. Use this when the Integration Service runs in ASCII mode and you want the procedure to access data in Unicode. eASM_MBCS. Use this when the Integration Service runs in Unicode mode and you want the procedure to access data in MBCS.

The return value datatype is INFA_STATUS. Use INFA_SUCCESS and INFA_FAILURE for the return value.
