So what do you do in widget.cpp:116?
@Christian-Ehrlicher I convert string to int in that particular line 116.
-
Come on... please show the code and the input value.

Which I think is happening because not even one character of your string can be converted
I can see. It is "3"

Verify in the debugger my suggestion that
_Ptr == _Eptris true? And what is*_Ptr?While you're also responding to @Christian-Ehrlicher .

std::string dtObjects; bool ok = dt->getinfo("number_of_objects", dtObjects ); if ( false == ok ) { ui->plainTextEdit->appendPlainText("Could not retrieve information!" ); } int nObjects = std::stoi(dtObjects); ui->plainTextEdit->appendPlainText("No of Objects: " + QString::number(nObjects));and below you can find declaration of this getinfo function.
bool process::getinfo(const std::string& para, std::string& val)I am assuming somewhere wrong going during the process(like since i am using reference i might be doing somewhere wrong). Currently i am doing this thing will get back as soon as possible!

@aravmadd
And prove to us what isdtObjects? And what is your code doing since you allow it to continue afterfalse == ok--- why would you do that?? So for all we know this could easily be being produced becausedtObjectsdoes not contain what you said it contains.... -

int nObjects = std::stoi(dtObjects);
ui->plainTextEdit->appendPlainText("No of Objects: " + QString::number(nObjects));Shouldn't this be in an else {} block?

dtObjects
And how do you check that this is really a number?
Please read the docs and do what you have to when you don't do the sanity check by yourself:
Exceptions
std::invalid_argument if no conversion could be performed std::out_of_range if the converted value would fall out of the range of the result type or if the underlying function (std::strtol or std::strtoll) sets errno to ERANGE. -

I should keep that part in else block. When i was doing checks i found that then i also saw the same in comment. When coming to your question, it always gives the number of devices available, so that string always contains int values. like 3 or 4 or 8 not more than 9 .
But I would like to say sorry for everyone here because I completly lost in the code because i completly missed else block which is a big blunder.
But anways thanks for all the help. With all your comments i also got various ideas of debugging ideas which can be helpful for future. Thanks a lot
