View 2 RepliesActivated Event
Jun 2, 2010Hello, everyone! I'm having problems with the Activated Event in Visual Basic. When trying to click my btnNext, IF THE DATA ON THE PAGE IS NOT SAVED YET, then a message box is to appear and alert the user that the data is not saved yet. When clicking the OK button on the MessageBox, it is supposed to return control back over to the main form. HOWEVER, I can't get past the Activated Event on the main form. It crashes the program. I've tried global flags, but it still does not want to work! Can anyone please help? Any thought in the right direction will be greatly appreciated! Thanks in advance, y'all!
View 2 RepliesVB 6.0 To .Net Conversion - Form Activated Event
Jul 9, 2010We 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.
Activated Event In TopLevel=False Forms
Jan 19, 2010I'm having problem to get the Form.Activated (and .Deactivated for that matter) events to trigger for a Form with Form.TopLevel=False.
The reason why the form is TopLevel=False is because I need to put it in a tabcontrol.
Is there any other ways to detect when the Form is entered/activated?
VS 2008 : Override Form's Activated Event?
Sep 8, 2009I 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?

Communications :: TCP - Full Message Before The Data Arrival Event Is Triggered?
Jan 16, 2009When you Use Socket.Send Ether in VB6 with the Winsock control or Vb.Net sockets / Windows API does it generate that if you send "Hello" that on the other side it will get the Full Message Before the Data Arrival event is triggered??Or is it possible it can get it in two Different events like "He" & "llo" and a Last question, TCP is stream oriented, is there a Protocol that is Message Oriented but is wrapped with TCP, if not what is a good Delimitor to use with TCP, Usually ide use &H1 OR &H0 but I assume &H0 is common.. or Should I just add a Length Param before each Packet I send..?Now if thats the case and I got the Delimitor route... What if Im sending Chunks of 8192 of a File in a while loop and on a different thread I send a Command if I use the Length Param isent there a huge chance that the messages will get sent like this
[code]...
BUT the issue lies as it thinking that only the 3 of 4 of the incomming file Frames are getting Recv due to it not knowing which frames are for which. Mainly due to me sending a big burst and on the other side recving random chunk sizes on the other side.Edit: Got another question, If I send two bytes across the internet via TCP, will they ever arrive as two different I belive the term is Frame or is that only when they exceide the size of the MTU will the Message be Split. The reason why is if I send a Header saying SOH, Length Of Message(2Bytes), thats 3 bytes can I say 100% of the time the computer on the otherend will recv that all at once so I can parse it? And What ever happen to Flush for Winsock?

View 6 RepliesDisplay Text When ComboBox Is Activated?
Sep 21, 2011I have a combobox and a rich text box. When I select different items in the combo box, I want some text to appear in the rtb next to it. Such as, selecting "Dog" in the combobox puts "Golden retriever, lab" and etc in the rtb.
1) I don't know what kind of event handler would trigger the combobox. I tried a click event but it's crashing so I want to know if there's a different way
2) How do I find what the user selected in the combobox, so it can display stuff in the rtb accordingly? I thought it was .Items.IndexOf but nothing seems to be working so.
Form Activated And Deactivate Events
Apr 3, 2011This 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.

So I thought I would share it:Click Button 1 on Form2 and Form1 comes back to life!
View 12 RepliesWinforms - .net Activated Fires Multiple Times?
Sep 22, 2011I want to update a database based on the form that is currently activated. I had originally decided to use the GotFocus event. However I now understand that will not work as the form has controls on it. So I then thought I wouls use the activated event. This works but seems to fire multiple times. I put in the following code:
Private Sub frmNewTicket_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
MsgBox("Form Activated")
End Sub
I select the form and make it activated and the message box appears about 15 times.Why does it do this? How should I handle this. I only want my code to execute once when the form is activated.NOTE: There are several forms that the users will be changing between, incuding forms from other applications.
