put the needed dlls beside your exe or set the PATH environment variable to contain the path to mingw10.dll.

I have set the PATH environment variable..but it says QtCode4.dll is missing !!

QtCode4? what's this? or do you mean QtCore4.dll?
Then the path to this dll is miossinmg :-)
You have to add it also.

sorry..that was typo..QtCore4.dll is correct..but where will this DLL reside ?

you find it inside your Qt installation
depends which version you installed
In Qt SDK with Qt 4.7.2, look here:

<QtSDK Dir>\Desktop\Qt\4.7.2\mingw\bin

Could be some missing image format plugins. Please look in the forum search for "imageformats plugins", it was discussed recently with some hints about how to resolve this issue.

1.load icons depending upon the drive type in my tree widget
2.if it is CD-ROM drive disable the user section

could somebody guide me on this !!!

Again (mentioned this before, I believe), take a look at QFileSystemModel. It does this for you already. If you don't use it yourself, then you might study its source code to find out where it gets the images from. Or, look into QFileIconProvider.

If you are using QSystemStorageInfo as your data source, then you also know which drives are a CDRom drives. Set the correct flags for those drives, and presto.
