QString conversion to char format

esbxp

Hello :

I need have this ?

@char buffer[80] = "";
sprintf( buffer, "%s%s_04i.%s", "C:\Test\MyImage", "Sector_", index, "png" );
@

the result will be :

@"C:\Test\MyImage\Sector_00000.png
"C:\Test\MyImage\Sector_00001.png
"C:\Test\MyImage\Sector_00002.png
"C:\Test\MyImage\Sector_00003.png
@

hmm ... but then the dialog "lineEdit", return a QString ...

@
QString strCache = ui->edt_CachePath.text() //. Return QString not char;
QString strSector = ui->edt_CacheSector.text() //. Return QString not char;

QString strResult = "";

for(int index = 0; index< 1000; index+=1) {
QtextStram(&strResult) << strCache << "/" << strSector << index << ".png";
strResult = "";
}
@

the result is:

@
"C:\Test\MyImage\Sector_8.png"
"C:\Test\MyImage\Sector_9.png"
"C:\Test\MyImage\Sector_10.png"
"C:\Test\MyImage\Sector_11.png"

//. Remember sprintf () is : "C:\Test\MyImage\Sector_00008.png"
@

Hello:
Sorry I Find the Alternative Solution .... Thanks !!!

@
#include <QCoreApplication>
#include <QDebug>

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

QString strResult = "";
QString strCaches = "C:\\Test\\MyFolder";
QString strPrefix = "Sector_";

//. [1]
for(int index=0; index<10; index+=1){
    strResult = QString("Sector_%1").arg(index,5,10,QLatin1Char('0'));
    qDebug() << strResult;
}

qDebug() << " ---------- Case 2 -------------- ";
//. [2]
for(int index=0; index<10; index+=1){
    strResult = QString("%1\\%2%3").arg(strCaches).arg(strPrefix).arg(index, 5, 10, QLatin1Char('0'));
    qDebug() << strResult;
}

return a.exec&#40;&#41;;
