So imagine you need to copy a whole chunk of text into multiple rows in a table where you have a threshold of “x” number of characters per row. Here is a code I created to chop the text up with the SPACE as a delimiter. It puts the rest of the text on the next record until all texts are inserted. This code is located in the methods of the table that it is inserting it to and called in the modifiedfield method.
void CutText(str _textToCut)
{
int threshold;
str delimiter, origText, curText;
int nextLineNum, curTextLen, trimPos, nextTrimPos;
NarrationTable narration;
;
threshold = 74;
delimiter = " ";
curText = _textToCut;
origText = curText;
//check how long the text is
curTextLen = strLen(curText);
//deal with the first record to insert first
if (curTextLen > threshold)
{
//find position. Note a negative value in the last parameter means to start searching from the back of the text
trimPos = strfind(curText,delimiter,curTextLen,-curTextLen);
if (trimPos > threshold)
{
//find the first position
while (trimPos > threshold)
{
curText = substr(curText,1, trimPos - 1);
curTextLen = strLen(curText);
trimPos = strfind(curText,delimiter,curTextLen,-curTextLen);
}
//insert the first text
this.Notes = curText;
//if new insert, if not, just save
if (!this.RecId)
{
this.LineNum = this.GetLastLineNum(this.SecondaryId) + 1;
this.doInsert();
}
else
this.doUpdate();
}
//insert the rest in a new record
curText = substr(origText,trimPos + 1,strlen(origText));
trimPos = strfind(curText,delimiter,1,curTextLen); //remove extra word
curText = substr(curText,trimPos + 1,strlen(curText)); //remove extra word
origText = curText;
curTextLen = strLen(curText);
//go through and cut up the rest of the text and insert it and cut it until all text can fit within the threshold
while (trimPos)
{
trimPos = strfind(curText,delimiter,curTextLen,-curTextLen);
while (trimPos > threshold)
{
curText = substr(curText,1, trimPos - 1);
curTextLen = strLen(curText);
trimPos = strfind(curText,delimiter,curTextLen,-curTextLen);
}
ttsbegin;
select forupdate narration
order by LineNum desc where
narration.SecondaryId == this.SecondaryId;
//there should always be a record selected. but juse in case...
if (narration)
{
narration.LineNum = narration.LineNum + 1;
narration.Notes = curText;
narration.insert();
}
ttscommit;
curText = substr(origText,trimPos + 1,strlen(origText));
trimPos = strfind(curText,delimiter,1,curTextLen); //remove extra word
curText = substr(curText,trimPos + 1,strlen(curText)); //remove extra word
origText = curText;
curTextLen = strLen(curText);
trimPos = strfind(curText,delimiter,curTextLen,-curTextLen);
}
}
}
