I found a problem with QSettings when trying to read from registry.
I am using Qt 4.7.3 so I would appreciate if anybody can check with Qt 5
at least.
Problem:
QSettings fails to return specific key value (Common AppData) when read
other keys at the same level just fine.
Key exists and verified with regedit.
Test case is below:
#include <QApplication>
#include <QSettings>
#include <QDebug>
void ddd2();
int main(int argc, char *argv[])
{
// execute test and return
QApplication a(argc, argv);
ddd2();
return 0;
}
void ddd2()
{
QSettings
reg("HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Shell
Folders",
QSettings::NativeFormat);
QString key;
QString val;
key = QString("Common AppData");
val = QString ( reg.value(key).toString());
qDebug() << "key: " << key << " value: " << val;
key = QString("Common Desktop");
val = QString ( reg.value(key).toString());
qDebug() << "key: " << key << " value: " << val;
key = QString("Common Documents");
val = QString ( reg.value(key).toString());
qDebug() << "key: " << key << " value: " << val;
}
Output:
key: "Common AppData" value: ""
key: "Common Desktop" value: "C:\Users\Public\Desktop"
key: "Common Documents" value: "C:\Users\Public\Documents"
Expected
* WinXP: "c:\Documents and Settings\All Users\Application Data"
* WinV/7/8: "c:\ProgramData"

Alex
