[Microsoft][SQL Native Client]Invalid character value for cast specification

I have an old code in VC++ and MFC which is creating command to call a stored procedure like this:

CString spText;
      spText.Format ( "{call GetMailData(%d,%d,%s ,%s,%d)}", activityRecordData.entityNumber,
            activityRecordData.rttiTypeID, activityRecordData.addrTypeID, activityRecordData.corrMethID,

Now while executing I am receiving error  "[Microsoft][SQL Native Client]Invalid character value for cast specification" even though the SP works fine in SQL Client.

The reason I think is %s because if I remove %s variables from the code and comment varchar parameters in Stored procedure, it runs properly. Any way to pass the string variables properly?

To run the SP:

GetMailData 3040047,10,HOME,SMTP,3060

notice that I am not passing HOME and SMTP in quotes..

ALTER PROCEDURE [dbo].[GetMailData]  
   @EntNo int/* IN must - entity Number*/,
   @rttiTypeID int/* IN must - entity type*/,
   @addrTypeID varchar(4)/* IN optional, address type Id (Home, Offc, etc.)*/,
   @corrMethID varchar(4)/* IN optional, correspondence method ID*/,
   @docGroupNo int/* IN must - document group number*/

Hey jkr,

 I think I got this working..I tried this command by adding single quotes around ' %s' and it worked..WTH :)

 "{call GetMailData(%d,%d,'%s' ,'%s',%d)}"

and the debug watch shows this call {GetMailData(3040047,10,'HOME' ,'MAIL',3060)}
Could you post the declaration of 'activityRecordData'?

const t_activityRecordData &activityRecordData

typedef struct {
      int holdingID;
      int refHoldingID;
      int refHoldingType;
      int docGroupID;
      char spName [MAXBUFLEN];
      int entityNumber;
      short rttiTypeID;
      char addrTypeID [CODE_LEN+1];
      char corrMethID [CODE_LEN+1];
} t_activityRecordData;

Weird... but if it works.
string literals always need to be quoted.

you need to make sure that the strings don't have a single quote ' character in the text. if so they must be escaped by doubling them.

I added the single quote around '%s' and the solution worked
