Hello people I am new here and also new to Qt4 though i have much experience with C++ :) . Just started Qt4 today but the problem I am facing is:
When I run the .exe file of my application from Debug or Release folder i get error of "qtcore4.dll" missing and "qtcored4.dll" , can anyone help out with it ?
And what if I want to send the application to my friend then how can I properly make the application and send it to whom I want to?
:o

This is clear.
Your Qt program needs Qt dlls to run. So add Qt path and Qt bin path in environment variable PATH.
e.g.
PATH += C:/Qt/4.5.2
PATH += C:/Qt/4.5.2/Bin


And what if I want to send the application to my friend then how can I properly make the application and send it to whom I want to?
:o 2 Ways for that :
1. You can build Qt statically and then build your application.
2. You can send required Qt dlls along-with executable.

For more info about deployment see this (http://doc.trolltech.com/4.5/deployment-windows.html).

should I set the enviroment variable path in .pro file or should i do it in My Computer properties>>advanced>>enviroment variables and then add path?

This option is correct. For safety do log-off and log-in again after editing path variable.

I am still getting that error even after setting the path :( , is it necessary for it to be installed in C drive?cause I have installed it in my D drive

No, that was just an example, install it anywhere you want.

are you using VS integrator? if so, maybe you need to add the path to the VS (qt->builds, "Version Name: Qt_4.5" "Path: C:\Qt\2009.01\qt" (default installation file of the integrator))

And I'm not sure, but maybe you need to have the framework 2.0 installed.
