Now we can create a database table with 4 columns and 6 rows, it is optional because SQL server wizard automatically created a table when we import data. After that select Tasks, then select import data by pressing enter key.
Figure 6: FlatFile Step 7: Select header row delimiter. In this window, select File name and browse the file where your file saved. After that click on next button. Figure 7: Select text file After selecting the text file as in the following image, click next.
Here select an option where you will login your SQL Server. If you want to import data in the default table, then you can insert, otherwise you are selecting your database table.
After that click ok. Now click on Finish Button. I don't want to change anything on these things like creating a new object. I only want to I guess open the. Also the ability to write on the end of the file with the user giving a username which will be written on the end of the file while also creating a new row then the password which will be written after the username with a space in between them and finally the starting balance which will be written on the end of balance.
The new rows need to be created too so that the different accounts will be distinguishable when they are put into the array variables. Oh and almost forgot the most important: being able to overwrite the file balance. As for my current code I will polish it up, making another menu allowing the user to create a new account.
I tried to search for these thing but everyone was doing their own special thing writing std:: in front of every line and using some random libraries I could not find a simple valid source. If it help I though about using something like: after I put the account. But my problem is how to search and I realized I do not know how to add a row to any array in case of a new account. Also I could work with 3 one-dimensional arrays userename.
I want to say thank you to everyone that has commented and tried to help me but let me make this a little bit more clear. This is basically what my teacher said:. So the tl;dr version of this as I understand it is I need to have the items listed on this list after some realization :.
The easiest method for using a text file as a database is to have fixed length fields. This allows for fast reading reading in blocks and you can calculate where the record is and seek to it. Be aware that if you want to modify the text file, you may need to write the entire text file to a new file. However, with a fixed width format, you can modify the records without creating a new file. Inserting, will require writing to a new file.

In my class, I prefer to set the columns through the code instead of doing this at the first line of the Database and in my opinion this is better to avoid future errors.
Then the headers of the functions would be:. I created this field to get and set the path of the text file. If it exists, great, otherwise we will create this file and use it as we have setted. Setting functions with the same name should be great to get a specific variable variable like, only the name or only the mail. Copy Code.
