View 4 RepliesWhat I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

I could be way off here, but it almost seems like ID.IDlist points to the address of mylist and so when mylist is cleared so is ID.Idlist. It seems as though the reason the second block of code works is because I am creating a new list in memory for each ID object and ID.IDlist just points to it... is that right?
I've got 2 seperated programs.
One is a program where you can select a product and select how many of them you want. Then the total price wil be displayedin a label. And the list of selected products will be saved in a .txt file.
The second program is an Edit program. The user can edit his selected products. Here he can change the total of a product.So if he had selected 1, he can change it to three or something. When the user clicks the button Save. The changes will besaved in the same .txt file and the total price will also be changed and displayed in program one.
Program one is compleet.Program two has problems and here i need your help:- the user can't make a change in the numbers, seems that the textbox is read-only or something. How to solve?- Then when i click save, the changed must be saved in the .txt ( i can't test this yet because no changes can't be made)- the total new price must be showed in program 1 (i think i programmed this well, but can you take a look)
Here is a part of my code of program 1:

For example if they enter "dog", "cat" and "fish" I want the autocomplete suggests to show these three options. So far my Code only shows the last user input.
