Refreshing First Datagrdiview-form From Activated Second Detailview-form?
Jul 8, 2009
I am working on supplier maintenance file. From mainmenu, opening first form shows records on datagridview through databinding. Clicking add new record, i fired a second form as my data entry with detail view through databinding, minus navigational buttons. I left the delete and save button only. Once through data entry, i save it on server. My problem is, how can i reflect the added record on the first form while i am on my second form? I prefer the new record be added only to the first form. I don't want the idea of retrieving the records again from my server.

I had issues in refreshing a form that is bound to different tables in a database. Various forms allow the user to change and add and update information on the form via the database. I had created a public sub in that form that the other forms could call, after saving the data, that was supposed to refresh the data on the main form. This was not working so I researched the problem. I came across this page which pertains to Form.Activated: [url]
I placed all of the table adapter fills into this event, instead of in Form_Load, and it seems to work now, when the form first loads, and when other forms update data. My question is does anyone have experience using this and what are the consequences, if any, in using this to reload/refresh the data showing on the form?

I created a DetailView of a DataTable in a Form. This also created a BindingNavigator and all of this works fine.However, one TextBox in the Form shows the LangaugeCode and I'd like to use my refLanguage DataTable to show the LanguageName instead. How do I go about doing that?

Basically I have two forms - Form1 has a DataGrid on it (Infragistics) and in the double-click row event it creates an instance of the EditForm and passes along the UniqueId for editing. Once the user saves the changes (if they make changes) - I want the DataGrid on Form1 to refresh. Here is how I thought I could get this to work ... I create a public property called RefreshRequired as boolean. Before unloading the EditForm it sets this property to true. Then Unloads. This continues the code in Form1 (which showed the EditForm as modal) but RefreshRequired is still showing as False? Why isn't my EditForm able to set the property?

I am trying to migrate a vb6.0 application to vb.net. I have a major issue while executing the code under form.activated and form.deactivate. There is a difference in behaviour between form.activate in vb6.0 and form.activated in vb.net. How can I simulate the behaviour of vb version in vb.net.
I have read that the form.activated fires even when the control goes to a different application and comes back.

This is a non-MDI windows application. I have a home form containing a panel named Panel1 and two buttons btnForm1 and btnForm2. Clicking btnForm1 and btnForm2 opens up Form1 and Form2 respectively in Panel1. Before a form is opened in Panel1, all opened forms in Panel1 are cleared. The code follows:[code...]
In which events should the above lines be written? In MDI apps this could have been accomplished by including them in Form_Activated and Form_Deactivate events respectively.
But here neither Activated nor Deactivate events fire when you open forms in frmHome.Panel1. Instead of Activated and Deactivate you can use Form_Load an Form_FormClosed events but they will only merge/unmerge menus if existing forms are closed before opening a new form in the panel.
But as I sometimes need forms to be opened and closed keeping existing forms opened, using these events won't fulfill the task. Even the GotFocus and LostFocus events won't work. So I want Activated and Deactivate events to be fired or some other means by which the menus and toolstrips can be merged/unmerged when the form gains/looses focus respectively.

We are converting a Visual Basic 6.0 application to vb.net 2008 and are having an issue, while executing the code under form activated event. There is a difference in behavior between form.activate in Visual Basic 6.0 and form.activated in vb.net. In Visual Basic 6.0, the Activate event was raised only when switching between forms in the application; in Visual Basic .NET, the Activated event also is raised in case of showing messagebox and when switching from other applications.(by msdn)
In vb6 application the purpose to use form activate event is, to execute some code when forms become active. In our application forms are loaded, hide and show in different flows. So whenever this form is shown from hide state or any of its child form return focus to it, we need to reflect different changes in the application to the specific form controls.
* For example user changes its application preferred language. * As the application is huge, so shifting logic to other place with respect to the current scenario might solve the problem for the current form but then I have to re think it for all other forms (which is very hectic and more or less not feasible). In the migration process it is required to make as little changes in the existing code execution hierarchy. So we need a similar behavior like form.activate in vb6.0 with some other event or restrict some functionality of Activated event in vb.net.

I'm trying to make it where you can click make a dialogbox lose focus until you input the requested information. I'm trying to create an effect where if you try clicking on the parent form, it flashes and won't let you activate it. You can see this effect in Windows sometimes when an error box pops up and you have to click 'OK' to continue. How would I go about doing this in VB.NET?

I have to two forms. Form one has several check boxes and when a button is pressed, a second form is opened and certain functions are ran based on which check boxes are selected.The problem is that the second form doesn't show until all of the functions are done.I decided to use the Form's Activated event, which works fine. However, the event fires every time the form comes into focus.Is there anyway to override the event and make it only fire once?

I am currently converting a 90s VB6 application to VB.NET. While testing I came across something curious.A Modal form by definition will prevent users accessing any other form in the application.This I discovered is not always true as I have a Modal form displayed which allowed me to access its owner form's Menu.Searching MSDN I could find no mention of this feature. So I thought I would share it:Click Button 1 on Form2 and Form1 comes back to life!

I am trying to refresh a datagridview from a second form to display newly written data. I have read the posts on this topic and can't figure mine out. My first form opens and you input data into text fields, etc. and then you need to select items from one table to copy and write to a new table. The datgridview on the first form shows the new table, and I have a new form that pops up to select the line items to add. Everything works perfectly except when I close the selection form after selecting lines, I would like the datgridview on the first form to refresh to show that the lines have been selected and displayed in the datagrid.
My data is loaded into the datagridview as so;
Public
Sub ShowVoucherLines()
cmd =

I've been working on this game the past few days, a simple game where two people control different tanks, and shoot each other, very basic so far.The problem I have is when one player is dead. I have the form recognizing each players death by using this code (It's within a timer subroutine)
'Player One Dead
If intPlayerOneHealth <= 0 Then
btnReplay.Visible = True
End If
[code]....
and that code is replicated for every key pressed (Arrow keys, WASD, e, and end). Those booleans are handled in a timer subroutine, where if the boolean is true, they will move/shoot. (Turning the booleans to false is done in the 'Private Sub KeysUp' subroutine)
TL;DR How do I get the game to restart itself when a player dies and hits the replay button?
P.S. I've tried 'Me.Refresh()' as well, and that didn't do anything

I just have not been able to find the correct syntax for refreshing my form. The Labels are added to a shape container and I delete them from it as well. All code seems to work only there is a ghost of the label left behind.

I have a VB 2008 Forms application which does Powerpoint automation.I am opening Powerpoint in a minimized window from within my app and am trying to periodically put update messages in a textbox on my main form while the automation is running (it takes a few minutes to complete), but my form window does not want to show these messages until the powerpoint operations are finished.It seems as if I need to force a window refresh or something on my windows form, but I'm unclear how to do that. Below is some code that I'm using that illustrates what I'm trying to do.When I run it, "Step One / Step Two / Step Three" do not show up on my textbox until after the Powerpoint automations are over.[code]

I have an mdi child form called "MyChild".
I need to refresh this form by calling the "MyRefresh()" method if the form has focus, and no controls have been clicked on in this form for the last 60 seconds.
Is there an efficient way of doing this ?
In the activate event of the form I could set up a timer and give it an interval of 60 seconds but what about checking for user intervention at any point in that 60 seconds ?

I have a databound combobox that displays a list of items, and I have a windows form that opens after clicking a button that allows me to make changes to the table that the combobox gets it's values from. When I make the changes and save them (successfully) and return to the parent window, the changes aren't reflected in the combobox. If I exit the app and launch it again the changes are reflected perfectly. I've tried me.combobox.refresh() on the forms GotFocus event, but no luck.

so I am a little confused. I am trying to refresh my datagrid when I have either add, deleted or edit a row via another form. I have it so my main form shows the datagridview, I have bound my controls to the database and I see all rows, no problem. I also have it setup to double click a row and it brings it up in another form to edit that record. This works. but it doesn't refresh the datagrid when saved. I am trying to follow this thread, specifically this post Refresh Datagridview - Post 2 Here is how I am loading the datagridview in main form

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.

The following code does create a form within a form and does place NotePad inside the child form. You have to manually start NotePad prior to execution (I work on that later) but the code does workŠ My problem is now I want to manipulate the properties of notepad i.e. focus, size, location, etc. but I cannot figure out how to reference notepad and its properties.
