Hello,
I have been using a numeric keypad to enter data into my application. I have to run a script because the data from the keypad is a string variable. Looking at the new v2.7 tool, and activity language, I was hopeful that there could be more simple code for the keypad to eliminate the string output and scripting.

Is there a simple command to convert a string variable to a integer variable that I can execute in Powervision (2.6, 2.7)?

Thanks.
Russell

The keypads use strings to accomodate alpha characters and special characters like decimal points.
If you would like to convert the string to a integer or a double these features have been added to the script function library in 2.7. Please be aware that in 2.7.10306 the string to integer function has a bug that is being fixed.

Here is some sample code: This script converts then writes the string 12345 to two text gages on the display labeled MyInt and MyDouble.

void $ConvertStringsToNumbers$ ()
{
int TempInt;
double TempDouble;
string TempString = "12345";
uint DoubleHandle = VariableIDs.MyDouble; //get the handles for all the main screen widgets
uint IntHandle = VariableIDs.MyInt;

TempInt = StringToInt(TempString); // take the string and convert to a Integer
smWrite(IntHandle, TempInt); // then write it to the Int text gage

TempDouble = StringToDouble(TempString); // take the same string and convert to a double
smWrite(DoubleHandle, TempDouble); // then write it to the Double text gage

}
