I have two textboxes...on the textchanged event of one textbox, readonly property of other textbox gets defined...e.g. first textbox is retrieving data as add,update,delete...when the first textbox text is changed to update then & then only second textbox readonly property is set to false...Now the problem,I am facing is....whenevr first textbox text is add,delete,its working fine..& second textbox is fetching the correct data..but once first textbox data gets changed to update,second textbox data remain unchanged though its readonly property gets changed correctly..it shows the same data as it was showing the first time when first textbox was changed to update...but after that,its data is not changing.
I am working on a huge multiform project for my company, and one of the few issues I am having is that when I am on the Main Menu Form, then go into a specific form (i.e Sales Order, etc.), do updates, changes, or just view data then close the Sales Order Form, if I happen to go back into the Sales Order Form without closing the entire project, then the Sales Order Form will display data instead of opening a blank form like when I first opened it.
Is there something that I should be adding to the Form Close Event to dump all of the data or refresh the data adapters so that if I open the form again, it will display a blank form that is ready to be used like when I first opened it?
I have tried using; Me.Dispose() Me.Close()
when closing these subforms, but if I open them again, the data fields (combo boxes and text boxes) will have random data in them.
I have 3 text boxes that are related on a form. They come from the same dataset and the same table in the dataset. The 3rd textbox is defined in the table as the product of textbox (really the column) 1 and 2. The problem is when I save after changing textbox 1 or 2, 3 does not update reflecting the new product. I have a different form using a different dataset that does a similar setup correctly. What could be the difference between the 2 forms or tables or dataset that I could look for?
It uses a Drawmap() sub with map data to create the map on the game load, but I can't seem to get it to refresh, and then re-draw the map based on player location. For example, if the player walks into a door, then it refreshes the map to show them in a building. Any advice on this? Code below:
Imports System.Drawing Imports System.Windows.Forms Public Class Form1
This looks like an easy fix but I can't figure this out. I'm trying to have button click event on a subForm (NewTournament), add a record to a database, and then to notify a data grid which lists the records from the same database automatically (the grid is listed on HomeForm).I so for am able to update the database and call upon a new window. But I can't get it to refresh that datagrid for anything. I know I'm supposed to clear the datagrid, get changes, then refill the grid. But everytime I do this, the code is NOT updating. Furthermore, I can very well see that the record is being added.
Private Sub CreateTournament_Click(sender As System.Object, e As System.EventArgs) Handles CreateTournament.Click ' Check the form for errors, if none exist.
I'm facing a problem with a datagridview datasorce, or refreshing it. I'll try to explain what is happening. So I have a datagridview called dgvMaterials, I'm binding datasorce to the datagridview from one table in mySQL server. Here is the code:
Dim ds As New DataSet Private Sub frmSettings_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
I have some processes that run as a background job, allowing a user to continue to use a page, when the jobs are finished (which can take a few minutes) i want to display a message to the user, the best place to display this would be the masterpage AFAIK (incase they move from page to page on the site) so i have defined a div in the masterpage file.
I am trying to find the best method for displaying the data, at the moment i have a method in the masterpage vb file which polls a database to see if the job(which involves complex logic and some db access) has completed, if it has, it shows a message in the div e.g. "Job 13132 has completed" - which works fine.
The problem is this is not dynamic, and i have to refresh the page to call the function that checks if the processes have finished, how can i use AJAX to deliver this content automatically every 5 seconds?
I have tried using an asp timer with a 5 second tick time but the entire page refreshes on the timer click event every 5 seconds.Protected Sub Timer1_Tick(Byval sender as Object, Byval e As EventArgs)
[Code]...
Is there a way to only refresh the div with the updated message, without a full refresh happening using this code? Or if this is not possible, is there any way to replicate the above function using jQuery and still be able to update the DIV text only if a job as finished?
I have two dropdownlist, one is State and one is City. When a State is selected, the City dropdownlist becomes populated. At that point you can select a city, however if you select a city and go back and select a different state, the city dropdownlist is populated by the cities for both states. How do I get it clear the cities for the first state?
Here is the code behind
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load End Sub
i had insert data to my database.and it run perfectly like i want.but when i refresh the server explorer all the data that i inserted using my form is lost when i debug it again.
I'm currently coding an ATM system in VB, and when a user picks a card to 'log on' with, they have 3 attempts to log on before the card is confiscated. The card numbers are in a combobox (which are retreived from an SQL database using the DataAdapter), and each card has a boolean 'confiscated' field in the database.
have a main form that displays a users score.I hide the main form when going to a child form.When that child form is closed, it will show the main form.The problem is that the datathat has been changed when going to the child form is not displayed on the main form since it has not been closed.Is there anyway around this?
I'm currently coding an ATM system in VB, and when a user picks a card to 'log on' with, they have 3 attempts to log on before the card is confiscated.
The card numbers are in a combobox (which are retreived from an SQL database using the binding source which is linked to a data adapter), and each card has a boolean 'confiscated' field in the database.
It does actually set the card to confiscated after the 3 tries, however I'd like the form to 'refresh' so the card no longer appears in the combobox, without having to close down the form and reload it. Is there a way to do this? I've tried refreshing the combobox and data adapter (.Refresh) but this does nothing
I load up a datatable - bind it to a binding source and a binding navigator - and lots of textboxes on the screen bound to that as well.When I get a concurrency violation - another user has already changed my vendor, let's say - what is the best method to go about refreshing the datatable with current data from the DB?
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 ?
I have a DataGridView on FormA and a DataGridView on FormB. The DataGridView on FormA is initially populated from a file. This same file is being reused when data is saved from either form.
What works: I show FormB by clicking a button (control) located on FormA and all of the data that is in FormA's DataGridView is read into the one on FormB from the file. I can make changes to the DataGridView on FormB and save back to the file but when I close FormB, the data on FormA remains the same as originally read in.
What is needed: If I make changes on FormB, what is the best way to refresh the DataGridView on FormA when I return to it? FormB is closed at this point. I tried to include a call (as the last statement) in the button control on FormA to read the data from the file again as this works initially but nothing happens.
Note: the FormA's DataGridView is also in a Tab control if this makes any difference to try and get it to refresh.
I have setup a page in Excel with several textboxes for data entry. I would like to be able to tab from textbox to textbox so I can enter this data as quickly as possible.
I want when Push Button data from Excel(The next cell data) go to the next Line in Textbox.

I am trying to click on certain rows in a datagridview and have the information in the rows sent to a textbox. It does not append each row to the textbox though, which is what I want it to do. it just replaces it with the row I click on. What's wrong with my code. I have tried cell click too.
Private Sub dgProducts_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles dgProducts.Click Dim i As Integer
I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
I have a form that uses a tab control. On the main tab is a DataGridView containing Customer information. If I double-click on a row in that DGV, I go to another tab in which I can either make changes or delete the record. Whatever I do, whether it be delete it or modify it, after clicking on the appropriate command button, focus goes back to the main tab. What I wish to do is have the changes be reflected on that DGV. If the record is deleted then I want the DGV to not have that record present. This DGV is bound to a BindingSource. What control/dataset to I need to "Refresh" in order for this to happen?
I have a VB (2008) program that I wrote that will not refresh the info in a textbox. I've tried to refresh, update, hide/show the data but cannot get it to work. Here is a code snippet:[code]The concept of what I'm trying to do is quite simple. the user selects one or more sites to check, the program shells out and SSH's into the device(s), grabs the output an parses the data. It then turns different boxes to different colors based on the output. The maddenign thing is it works for the first time through and sometimes the second, but never any farther.At the end it paints everything just fine and if I insert a blank msgbox within the code it refreshes fine as well.
