Dynamic Textbox Data Has Been Changed?

Mar 3, 2009

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.

Asp.net - Data Not Being Changed In TextBox?

Dec 16, 2011

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.

Saving Changed Data Before DataViewGrid Selection (Row) Changed?

Jan 20, 2010

on 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?

Forms :: Dynamic Data Updation In A Textbox?

May 30, 2011

I 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 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.

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

VB 2008 .suo File Needs To Be Changed/recreated Because A Path Has Changed. All Other Files Are OK

May 5, 2012

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?

Detect That Data Has Changed On Database?

Oct 28, 2010

'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.

Ascertain If The Tableadapters Underlying Data Has Changed?

Aug 3, 2011

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?
