I want to know if thanks to a function, we can get a caractere at a specific place in a line.
For exemple, I have the line :
a,z,q,1,2,4
I want to get the caractere at the 3rd place, it's 'q'.
I have created this function :
char* getValue(char* res, int numArg) {
int lengthRes;
char *line = NULL;
int lengthLine;
GetTextBoxLineLength (panelHandle, PANEL_LIGNE, 0, &lengthLine);
line = malloc(sizeof(char) * (lengthLine +1)); //alloue une partie de la mémoire pour la chaine de caractères
GetTextBoxLine (panelHandle, PANEL_LIGNE, 0, line);
//We get what we have in PANEL_LINE
//We 'parse', then we have "\n" instead of ","
for (int i = 0; i< strlen(line); i++) {
if(line[i] == ',') {
line[i]='\n';
}
} //all comma in 'line' are replaced by \n
ResetTextBox (panelHandle, PANEL_PARSE, line); //We display 'line' after replaced commas, we will have several lines
GetTextBoxLineLength (panelHandle, PANEL_PARSE, numArg-1, &lengthRes);
res = malloc(sizeof(char) * (lengthRes +1)); //alloue une partie de la mémoire pour la chaine de caractères
GetTextBoxLine (panelHandle, PANEL_PARSE, numArg-1, res);
//The value of "res" correspond to "numArg"ieme line of 'line', so at "numArg"ieme field
return res; //We return "res", that the value we were wanted to have
}
But, when I have many lines to analyse, it take a lot of time, because of th rewritting in the Box etc...
Can you help me please ?
