Parameter type mismatch error

[Crystal Yang]

hi

I got Parameter type mismatch error during running my cvi application,

Parameter type mismatch:

expecting double but found pointer to double

the relative code is:

 sprintf(str,"\nMobile Phone-> %s, Batt.Volt: %3.2f V, SN: %s",g_szDutName,g_vArrayVol[i],g_szDutSn);
            OutputResult(str);

I know it is the setting of g_vArrayVol[i], i set it ViReal64 g_vArrayVol[4][32] in the *.h file.

Maybe this is a little bit stupid question, but I really can not solve it.

Hope anybody help me.

Crystal, as you say your data array is defined as g_vArrayVol[4][32]

I have stressed out the dimensions since your problem is directly involved with them: when you are printing out the battery voltage, you are passing to sprintf  g_vArrayVol[i], thet is the address of the whole 32 elements array of index [i] (let is to say, the whole i-th row in the matrix); the error you are finding states exactly that the parameter passed to sprintf is an array (i.e. a pointer to a memory area that stores actual data in double format) and not a double precision variable.

You should instead pass an individual element in the 2d array, as an example g_vArrayVol[i][0] .

Same opinion...
