这个怎么做到画面切换德呢？看里面的语句都一样啊。按钮里面的语句如下#include "apdefap.h"
void OnClick(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName)
{

char szPictureName[ 260 ] = "";
int iIndex = 0;

iIndex = SSMGetIndexFromObject( lpszObjectName);
SSMGetAreaFromIndex(iIndex , NULL, 0, szPictureName, 260);

SSMChangeWorkField( SSMGetScreen( lpszPictureName ), szPictureName, TRUE );

}
