I have a form that builds and populates dynamic text boxes from parsing a file. There is a "Last Name" text box that when populated, also labels a tab page with the name. After the form is populated, the user can change data as they desire but I was wondering how to update the tab page text when the user updates the last name text box? All the controls are built in code.

Ok, I have been going around and around with this for hours (Searching, etc). This is what I want to do, I want to load data into a Text Box and if the user changes the text in the Text Box I want to be able to save the new text.
My problem in the TxtBox_TextChanged event the data contained in the txtNarrative Text box is the new data that the user typed in (<>ABCD) but in the btnSubmit_Click event the data contained in txtNarrative is the original value ABCD.

In vb.net using Data Reader while selecting an value in combobox should display an selected value record from the database into textbox.
View 4 Replieson my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?
View 2 RepliesI am working on an application which involves serial port communication with stepper motors. Now I am sending queries to the PLC via modbus protocol. There is one query in which I ask the PLC for the current position of the moving motor and display it in a current position textbox using a DO Loop. Here the problem is the textbox only displays the position at the end of the motor movement and not while the motor in movies though I have included the code to do so inside the DO loop.

I wanted to simply on click a button to add those newly created textboxes to an array of textboxes. Starting with those labeled "Address". But I am finding this very difficult. I am able to add those originally on the form into the array very easily. But am unable to add the newly created textboxes into the array.
Here is my code so far below.

Dim MyBoxes() As TextBox = {Address, UserName, Password}
Dim Numbox As Integer = 1

View 2 RepliesI've never come across this before:I have a series of text boxes. The text of these boxes get set on page load. then I have a submit button that calls a sub to update the table with the new values (text) in the text box. The problem is it is keeping the original text not the text that is CURRENTLY in the textbox. Anyone come across this before? Or know how to get round it?

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
View 1 RepliesI want to detect when the user has changed the content of a Textbox.
The following does not work for me, because: When the user navigates through the database (using my navigation buttons), the textbox is also changed, but NOT by the user making input. I would only like to know when the user EDITED the Textbox.
Private Sub mskStudentNumber_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles mskStudentNumber.TextChanged

Basically what im trying to do is have a "Set to Current Page" button.
Is there a way to retrieve the URL of the current selected tab's url if the
navigation textbox text was deleted.
Normally i would do:
Form1.TextBox.Text = My.Settings.Homepage
But what if the person accidently changed the url in the textbox? or deleted it completly?
How do you retrieve the url of the web page the person is on? and set it to their homepage?

I have some textboxes bound to a bindingsource and bindingnavigator.
I want to detect when the values have changed and prompt the users to confrim if they want to update.
When the form is first initalised and when then binding navigator moves to the next record the text_changed event fires on textbox where I have a boolean to determine if things have changed.
Is there a way to set my boolean only when valid data changes have occured or a better way to detect if things have changed
I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"
VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.
The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'
Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.
I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?

On my form with my detailed layout of my database in textboxes i can change my data or add new record.
how can i verify if there was any changes to a record when the form is being closed or when my cancel button is pressed.
i want to create a message box that warns tha there hav been changes made should it be saved yes or no
'm developing multi user systems where for example I could have a form with a list of users on it. If a user on another system adds a user then I would ideally like for the new user to show up on my list reasonably soon. While that could be done by getting refreshing the list every couple of seconds I would prefer to be able to identify that a change has happened and then be able to decide what to do from there (whether that be actually refresh the list or inform the user that a change has happened and ask them what to do).
The only way that I can think of doing this is to store the information that was originally retrieved and then every x number of seconds requery the database and then compare the two sets of data, if there are differences then raise an event.
I am retrieving data from my database using a TableAdapter. I was wondering if there is some way I can tell (or be informed) that the data has changed and I therefore need to do another Fill? That way I can just Fill on demand rather than every time the user requests to see the information and I am forced to do a Fill before showing the data because I don't know if is current or not. For the record I am using an ODBC connection string to access a Pervasive PSQL database
EDIT I was thinking I could check the last write time of the MKD file to check if this has changed but this doesn't seem to be reliable as it is not written to until the connection is closed. Does anyone know the circumstances when this is written?
A quick question on caching dataset objects. How can I know if the data is changed in Sql when caching data? I don't want to specify time constraints but used a strategy where data is changed in sql and I have to refresh my cache?

I know I can exit a program by using the End statement.
But i was wanting to know how to check to see if the data has been changed since it was loaded and bring up a diaglog box up saying the data has been changed or not saved, would you like to save the data before exiting?
I will have a form that will have a yes, no, and cancel buttons.
