how to check the application product version??

[nish]

i use my application's return value to determine various things

MyApp

#define VERSION 142 //version 1.4.2
 
int main(int argc,char** argv)
{
  QApplication app(argc,argv);
  if(argc>1)
  {
     if(!strcmp(argv[1],"ReturnVersionAndExit");
        return VERSION;
  }
 
 .... 
 ....
}

#define VERSION 142 //version 1.4.2

int main(int argc,char** argv)
{
  QApplication app(argc,argv);
  if(argc>1)
  {
     if(!strcmp(argv[1],"ReturnVersionAndExit");
        return VERSION;
  }
 
 .... 
 ....
}

To copy to clipboard, switch view to plain text mode 

now your other qt application can start the QProcess with your application and check the code.

check App

QString program="myapp.exe";
QStringList args;
args<<"ReturnVersionAndExit";
 
int version=QProcess::execute(program,args);
//voila!! u got the version.:D

QString program="myapp.exe";
QStringList args;
args<<"ReturnVersionAndExit";

int version=QProcess::execute(program,args);
//voila!! u got the version.:D
