But in practice, problems mounting and writing to NTFS volumes in Ubuntu are not caused by `ntfs-3g` being missing--they are caused by other, more subtle, things going wrong. Fortunately, they are rare, virtually always correctable, and usually fixable with relative ease. + +I recommend that you post a new question detailing information about the drive you are having trouble mounting (including its size, make, and model). If this is not an external drive but is instead a partition on the same drive as your Ubuntu system, then specify its size (if you know it or can find out), whether or not it has Windows installed on it and if so what version of Windows, and specifically how you installed Ubuntu. Make sure to indicate if writing to the partition is the only problem you're having, or if you are also unable to mount it and/or read it. If you are able to mount the drive, you should include the output of the `mount` command (run just like that, with no arguments) in the Terminal.","I found out that ntfsprogs has write support for NTFS.

From the draft C++11 standard section `7.2` *[dcl.enum]*: + +> +> For an enumeration whose underlying type is not fixed, the underlying +> type is an integral type that can represent all the enumerator values +> defined in the enumeration.

This matters since apparently on some architectures, *char\** and *int\** can have different sizes as mentioned in this [comp.lang.c++ discussion: GCC and forward declaration of enum](http://compgroups.net/comp.lang.c++/gcc-and-forward-declaration-of-enum/1005825): + +> +> [...] While on most architectures it may not be an issue, on some +> architectures the pointer will have a different size, in case it is a +> char pointer.

The complexity that comes from an incomplete enum type can be avoided by requiring that the size must be specified. + +So my best guess is that compiler implementers were kept in mind when this feature was designed, and the committee found that the increased complexity of incomplete enums was not worth the benefits." +33749645,"Hello friends i want to generate csv file in my application in following format +[![enter image description here](https://i.stack.imgur.com/cooVj.png)](https://i.stack.imgur.com/cooVj.png) + +Whne in android i get followign type csv +[![enter image description here](https://i.stack.imgur.com/hfwnM.png)](https://i.stack.imgur.com/hfwnM.png) + +My code is a follows. + +``` +private class ExportDatabaseCSVTask extends AsyncTask{ + + File exportDir;
