Apona Banan does not need .net or Java or other kind of libraries. It however relies on Miscrosoft Visual C++ runtime libraries on Windows.You most likely already have the libraries, specially if you have latest version of Word installed. The setup programs have all the necessary runtimes bundled. You may need to restart your machine before the runtime libraries are active.

Installing: 

The download file is a setup program that will guide you through installation. After downloading the exe file run it. You would see a dialog like this.

 Clicking next will bring the license dialog. Read the conditions of license and if you agree, select  "I accept the agreement" and then click next.

After clicking next,  it will ask for the installation directory. You may leave default and hit next.

Then you will asked for Start Menu folder where the shortcuts will be placed in. Give a new name or chose the default and hit next.

Then you will be shown the summary of options you have chosen. Hitting next will start copying files.

If you for any reason, whish to cancel the installation, you can click canel while copying files.

Once all files are copied, shortcuts are created, you are ready to use the program. The setup program in its last step would ask you want to run the program.

By now, the program would be ready for use. You will also have a shortcut created in the programs menu bar in start menu.

 Running

Start the program by clicking on the link created in the start menu. A dialog box would appear if you are using a trial version. If you have purchased the software, then you should click OK and enter the serial number. Otherwise, click NO to evaluate the software.

 Then the program would load the dictionary and build spell suggestion list. This may take a few seconds depending on the speed of the computer.

Once loaded, you are ready to use the software. The Open button would allow to open text file, Pase would accuire text available in the clipboard. Hitting the Check Spelling would start the checking process.

The MS Word button is not active because the function is still under development. Once mature, it would allow checking spelling of Word documents. To check spelling of a text file, you hit the open button and select the file. Apona Banan has been tested with text files upto few megabytes (that is about over 200 pages of document). The larger the document, the more memory it would requrie. You can also acquire text from the clipboard. Place some bangla texts in the clipboard in your choice of application and click on Paste to access the text. Then you can check the spelling. Once spelling check is done, you may whish the save the result as a text file or put it back to the clipboard. The Save and Copy buttons are for these purposes. 

Effectiveness of the speller is highly dependent on the dictionary in use. As we are using Ankur dictionary for Bangla words, performance of the spell chcker is largely dependent on the spellings in that list. If you face known words being shown as not in the dictionary, please keep them adding. This wold help the speller collect more correct words. The addedd words will be also as suggestions when running next time. All the words you add, are stored in file cdict.txt. We would also appreciate, if you can share this custom dictionary.

We are improving the word list, in the mean time  you can help us by sending bugs, suggesting new words and in numerous other ways. Thanks for using our software.
