I have an .net windows device application. I have a small form where i want to scan one item in a text box and then scan the other in the next text box and when that is done once it is done i want to save to dababase automatically. And get the focus to the first text box automatically.
[Code]...
so i have a quite huge program. but lets say i have one label. and i want to save that. i have the code and everything for saving the text of the label. now i want to assign ctrl+s to automatically save the labels text once pressed instead of going through a menu to choose save.this is like a regular texteditor where u press ctrl+s and it saves.
ive used this
If (e.KeyCode = e.Control & Keys.S) Then
MessageBox.Show("Ctrl+S pressed")
End If
and
[code]....
but it doesn't do anything once pressed.im also using the keydown declaration for the form.
I want my app to take a picture, then save it automatically. Can I do that with the save file dialog or how would I do that?
[Code]...

we have a vb.net application with send and receive mailing also. Now we have added a session timer of 30 min but the users are complaining that they are facing a problem when they write a long text message or while composing they get busy in something else and when they return back to continue composing message , they are redirected to a session expiry page, and their long text message is gone forever. So I am new to this and I was thinking like , when the user is in compose message the text should be automatically saved to drafts like hotmail.

View 23 RepliesI have a texbox that I'm using for a P2P IM program. The box stores all messages but I cannot get it to automatically scroll down to the most recent IM when the box is full and scrollbars are necessary. eg. When a user gets enough messages that they must start using the scrollbars, when a new message comes, the scrollbars reset to the top instead of the bottom where the new message is. Here's the code for adding the message into the box:

The code above simply produced no results, it didn't move the scroll bar at all.

I have a multi line textbox (in a windows form in vb.net application) that displays values from an array. What I would like is to have the height of the textbox increase automatically so that all the rows are visible in the textbox without the need to scroll down. Also I would like to know how this will affect any controls directly below the textbox in question. ie if the textbox grows in size, will it push the items below it further down or will it overlap them?

View 4 RepliesI have a textbox that represents a primary key in my database. Because the values are nvarchars I can't automatically increment for a new insert. Instead I have to read a value from a drop-down, perform some magic, and create a new incremented value for the new insert.
I've written codebehind that does all this when the drop-down is selected. It works, in that it puts correct values into the textbox. However when I try to insert, I get an error that that field cannot be null.
I'm pretty sure it's because I'm doing this in the codebehind : myTextBox.text = newValue
which wipes out the binding the textbox should have : Text='<%# Bind("UniqueName")
How can I calculate the needed value for this field programmatically and set it back to the screen so the user can see it (and possibly override it) and still keep the databinding intact so I can create the new record?

View 4 RepliesIve got a Listbox which displays a data/record from a SQL database, it displays "Amount" and only numbers would appear. it has a datasource.
Goal: I'd Like to get the total sum of those numbers from the Listbox and Display it to a textbox automatically or by button click event.
I thought of two ways to do this, but I don't have a clue on what to do.
1. I tried summing it all up on that exact Listbox and display the total on the textbox, here's the code that i came up with..
[CODE]...........
But the data im working with is from a database, so i got this error:Conversion from type 'DataRowView' to type 'Double' is not valid.
2. I thought of having another Listbox and "Copy" the contents shown on the Listbox1 and then sum it all up on the Listbox2, then lastly display the Total on the Textbox. I did a little research on how to accomplish that but all the clue i found is that i have to disconnect the listbox data from the datasource from being bound, and reconnect it again.. I really don't have any idea on how i could do that with an SQL database.
Here's a quick flow on what im trying to accomplish to make things.
Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1
