Darnell:
I have a question on what you want your project to do. Do you still want to accept interactive input from each numeric control on your UIR or do you just want to accept data from the script file? If you want to do both, think about leaving your Update button accepting input from the numeric controls, and add a Run Script button to read the data from the script file instead. Your may also want to allow the user to select the script file as in ChillerParser.zip example I posted here.
To read from a script file, you don't want to read the file for each numeric control, you want to read the file once and update any numeric control as commanded by the script file.
As I suggested earlier, don't read the file one character at a time using getc(), read it one line at a time using gets().
It looks like you're making things more complicated using strtok(), strcpy(), and atoi(). Why not use sscanf() as I did in the example I posted? You can read your switch value directly to an integer.
Good idea testing for comments ("//").
With the format of your MMW chassis commands, parsing is even easier. Try someting like this.
fpScript = fopen (scriptName, "r");
if (fpScript == NULL)
{
sprintf(statusMsg, "Error opening file %s", scriptName);
MessagePopup ("File Open Error", statusMsg);
}
else
{
while (fgets (scriptLine, 256, fpScript) != NULL)
{
if (strstr (scriptLine, "MMW_CHASSIS") != NULL)
{
// found MMW Chassis command
// expect a command string and a switch value
items = sscanf(scriptLine, "%s%d",cmdString, &switchValue);
if (items == 2)
{
if (strcmp(cmdString,"MMW_CHASSIS_SW1") == 0)
{
panelHandleSetCtrlVal (panelHandle, PANEL_NUMERIC_1, switchValue);
BIT_CONVERSION(PANEL_NUMERIC_1, BINARY_READ_1);
}
else if (strcmp(cmdString,"MMW_CHASSIS_SW2") == 0)
{
panelHandleSetCtrlVal (panelHandle, PANEL_NUMERIC_2, switchValue);
BIT_CONVERSION(PANEL_NUMERIC_2, BINARY_READ_2);
}
// add else if blocks for other controls
// ...
else
{
sprintf(statusMsg, "Unknown command at line %d:\n%s",
lineNumber, scriptLine);
MessagePopup ("Script Error", statusMsg);
}
}
else
{
sprintf(statusMsg, "Error in script file line %d\n%s",
lineNumber, scriptLine);
MessagePopup ("Script Format Error", statusMsg);
}
}
lineNumber++;
}
fclose(fpScript);
}
