memo field from database to memory varible in a editbox

[karlaesponda01]

Hi, I have a memo field in my database and I want it to store it into a memory variable so that i can show it in an editbox and store whats modify from it, I was wondering, how can that be done?

Hi Karla

You don’t need to use a variable just specify the table.column as the data source in the attributes and the memo field will be data bound saving automatically.

Drag a memo field onto a canvas will automatically create the editbox for you and bind it to the memo field.

Hi,
I want to store it in a memory variable because I don´t apply the changes directly in my database, is there any way where I can do this?

Hi Karla

You can bind to a variable in desktop apps by specifying m.varname

Alternatively you can set the text in your editbox through code.

Thanks, and how can a define the type of a memory varible, meaning, I want certain memory variable to be character type that allows me to store more than 255 characters, but I can´t find how can I do that. Because the problem that I have with my editbox is that the memory varible I asigned to, it´s not allowing me to store more than 255 charactes.

Hi Karla,

There is no 255 limit on text. The string limit is 64k.

Create a public variable

public myvar = "hello world"

Drag an editbox onto a canvas section

specify m.myvar as the "data source"

edit the text and in the console type

? myvar

You will see the text as you typed it
