VS 2010 Auto-Save After Textbox Data Entered
Feb 13, 2011
Is there a way to save every time the user updates a textbox on the form? My reasoning for this is I don't want to lose all information typed into the form if they were to click on the "x" to close the form. I want the form to update whenever they type so if they forget to press a "save" button (or better yet not use a save button) the data won't be lost. I can use a textbox change event handler and code to update my dataset on every textbox in the form but it seems tedious.

I want a textbox to have autocomplete. I want the completion to be based off of text that has been previously entered into the textbox. My method of saving seems to work but when i close the program and re run it the autocomplete suggestions arent there anymore.

I have previously asked a questions regarding DataGridView control:[URL].. now I'm trying to make the first column to include an autosuggestion. ie. when a user types an ID(say, "12") then all the records that starts with it(ie. "12*") will be displayed as suggestion.
And upon clicking an ID, the corresponding product_name will be displayed on the next column. I think, I could do this using Validating() event of DataGridView.

I've got a (hopefully) quick question. I've got textboxes attached to a binding source on one of my forms, and when I add, then clear, the data for the next entry to be added a small problem arises. If the user has previously entered something into, for example, Textbox3 and the user does not have the data for Textbox3 the user cannot move to the next field unless something is entered into the box.

I want to validate a string in a textbox after a period.Lets say that it needs to be ".rad" (whatever). When I enter "radjesh.rad" and press "OK" it should check if the last 4/5/6 (whatever) characters (including period) are in the string. If I'd enter "radjesh" it should fail, but if I'd enter (e.g.) "radjesh.jrkrk" it should work.

I want to implement the auto recovery feature in my application. i.e auto recovery of data from power failure, system crash,etc. Since the program is an multiuser with different access levels to each user, I want to save the data in a file which can only be recognized by the program. I don't want to save the data in the db, as there are many modules in which this feature has to implemented, which will make me create an separate table for each module, for temporary storage.

how to code the "from" portion when an email via vb.net. I could easily do "mm.From= email@domain.com"...but for this project it needs to be sent automatically depending on which user is entering the information. So I have lets say a group of 10 users, anytime a specific user sends in an update on a project form, the email is sent to the manager from the person who it's been updated from. Any suggestion? They all have specific ID's. How would I code it to where I could get the program to find them by their ID and then get their email address from their ID?
Protected Sub SendEmail()
Dim ToAddress As String = ConfigurationManager.AppSettings("AstMgr").ToString()
Dim mm As New Net.Mail.MailMessage("Engineering.Systems@exchange.nscorp.com", ToAddress)

Is richtextbox can save a text within its control? What control in vb.net that could save the text being entered within its control paticularly, if any? I need somebody that could give me an idea on what control to use to save the text within the control. I'm not trying to save the text anywhere. I want to save it within the control. I don't have to save it with a filename and a path location. Just like this forum, which everytime you post and reply to a thread, you will have to enter your message in a certain workspace and after you submit, it will save within the control so everytime you open your thread you will see the messages. What control do I need to use in vb.net to do that?

I have a tool connected to access database. It retrieves the database based on certain input conditions from 4 textboxes, 1 list box. The data from database comes to a datagridview. I have to enter certain values in a particular column in datagridview and continue with my calculations.At this stage I wan to save my file with the data I have entered so far. Is there a way i can save this data into another file (for example say " SAMPLE"), so that when I open the SAMPLE file from my tool it should display all the values I have saved in the respective controls.

I am currently puting together a data driven application just for fun and to get to know sql. The problem i am having is on my new customer form I cannot get the data in my text boxes to save into my database table at runtime. I simply have 4 textboxes and a save button the code for my save button is as follows:
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim Connection As SqlConnection = MSDB.GetConnection
Dim mySqlCommand As SqlCommand = New SqlCommand
Connection.Open()
[Code] ....
All this does is bring up an error in runtime. How to get that to work when I press save the details in my text boxes are actually saved into my database table.
