SelectionChange Event Not Triggered When Form Minimized

Mar 25, 2011

I have an application with a DataGridView and WebBrowser controls. In the DataGridView I load a DataTable using BindingSource. DataTable is just a list of URLs. I use SelectionChanged event on the DataGridView to load a selected URL in the WebBrowser control. The problem I have is that when I minimize form to the tray, it for some reason triggers SelectionChange event multiple times. What's really weird is that if I minimize to the taskbar SelectionChange event doesn't get triggered. It also doesn't get triggered if I load URLs directly to the DataGridView. What triggers SelectionChange and how to get rid of it?

Public Class Form1
Dim URLTable As DataTable = New DataTable("URLs")
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim URLColumn As DataColumn = URLTable.Columns.Add("URL", GetType(String))
[Code] .....

Override An Event - TextChanged Event Not To Be Triggered When The CellClick Event Occurs?

Jul 20, 2010

I'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).

I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?

[Timer] Trigger Event Manually - User Must Wait For A Minute Before The Event Is Triggered

Feb 12, 2010

Eg. ""vb.net" timer event trigger on purpose". This application is meant to run at all times to download a web page every minute. To avoid freezing the UI, I read that the best solution is to move the code from a While/Sleep loop to a Timer that will be triggered every minute. The problem I have, is that the user must wait for a minute before the event is triggered:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Interval = 60000
Timer1.Enabled = True

[CODE]...

Is it possible to force this event to occur instead of waiting for it?

Resize Event Triggered Before Load Event

Jul 18, 2012

Following on from my post yesterday (how to anchor buttons/controls to various sides of the current form when the form is resized) I have run into another problem. I am setting the width of my datagrid to be 80% of the form width on a 'form resize' event with 10% of the width at either side so it remains centred in whatever size window is available. This works fine. (mydatagrid.width = me.width/5*4)

I then decided to dynamically set the width of the 2 columns in the datagrid each to 50% of the width of the datagrid. Again, this sub is called in the 'form resize' event. This fails because the datagrid hasn't loaded the data from my sql database when the first 'resize' event is triggered. I did a bit of testing (by placing a simple msgbox statement into the resize event and the load event) and it seems the 'resize' event is triggered three times before the form's load event.

how do I stop the resize event triggering when the form loads (or at least make the load event trigger first).

AfterRowUpdate Event Is Not Getting Triggered?

Sep 28, 2009

I am using VS 2008 and UltraGrid from Infragistics v 5.2

I have two UltraGrid objects on a Winform. While the AfterRowUpdate event gets triggered for one, it does not get triggered for the other. Here's the procedure of the offending UltraGrid event:

This does get executed:

Private Sub ugPatient_AfterRowInsert(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.RowEventArgs) Handles ugPatient.AfterRowInsert
e.Row.Cells("Courtesy_C").Value = "Mr."

[Code]....

The source file is different from when the module was built. Would you like the debugger to use it anyway?

Even if I rebuild by application, the dialog box does not go away.

Find Out What Triggered An Event

Jul 30, 2011

I'm having a really annoying issue which I can't get to the bottom of. I've got a NumberUpDown control which has a ValueChanged event. There is only one reference to it in my entire project which I have commented out to prove that it isn't calling the event. Even though the number is not being changed (the control sometimes isn't even in focus!) the ValueChanged event gets called. This is driving me crazy and I wondered if I could back track through the code to see what actually caused this event to trigger?

Validating Event Getting Triggered Twice In Maskedtextbox?

Aug 17, 2010

I am facing a issue while using the "validating" event of the maskedtextbox. I have an MDI form, in which there is a main form and a form acting as bottom bar. The bottom bar comprises of buttons for moving to "previous" and "next" forms. If suppose in the main form i have a maskedtextbox and the initial focus is set on it, then on the click event of the button (next; which is on the bottom bar form), it calls the validating event of the maskedtextbox twice. In the validating event of the maskedtextbox, i am checking some validations and if it doesnt pass, then i set [e.cancel = true]. just let me know the reason behind the triggering of "Validating" event twice?

Textbox_Leave Event When Triggered By Selecting Different Tab In Containing Tab Contol?

Aug 12, 2010

I have a textbox in a tab control and iv'e coded the textbox_leave event to show a msgbox and reselect the textbox if the text doesn't meet certain conditions.

Private Sub TextBoxChaseTime_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBoxChaseTime.Leave
If IsDate(Me.TextBoxChaseTime.Text) Then
Me.TextBoxChaseTime.Text = Format(CDate(Me.TextBoxChaseTime.Text), "hh:mm")[code].....
(Reselecting the textbox is the only way i can find to efectively cancel the leave event - is there another)

I've also added a line to also reselect the tabpage incase the textbox_leave event was triggered by selecting a different tab in the tabcontol.However, when the textbox_leave event is triggered by the user selecting a different tab the textbox_leave event seems to be triggered several times displaying the msgbox four times.why this is, but it seems to be caused by the by the line that reselects the tabcontrolhow to stop the msgbox being shown more than once Interestingly, if i add a line to change the text in the text box to meet the conditions the msgbox is only shown once, but the tabpage is not reselcted

Communications :: TCP - Full Message Before The Data Arrival Event Is Triggered?

Jan 16, 2009

When 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?

VS 2008 - Infinite Loop - Event Triggered Keeps Firing Off The Code

I'm not even sure what I need to know. None the less lets say I got a timer with an if event to check if said event is triggered then it fires off some code. The problem is if said event is triggered it keeps firing off the code and I only need to do it one time. Whilst letting the timer keep checking if event happened. I hope I worded that right and here is a rough translation in code. [Code] Is there a way to keep checking if an event happened and only fire off the code one time?

Forms :: Base Window Events Are Triggered When Focus Is On Another Form On Its Top?

Apr 3, 2009

I am migrating my code from vb.net 1.1 framework to vb.net 3.5In my windows application, the base window has some buttons and events are written for the same.I have shortcuts defined for these buttons also, for example: ctrl+d, DEL (keyboard) etc.Now i open a property Grid form on top of my base window for a selected object.Even when the focus is on this property grid, i am noticing that my base window events are firing on pressing those shortcuts.

example:I select some text in my property grid and hit delete button from keyboard. The delete event that i have written for the selected object gets fired and the text is not deleting.I fail to understand why is it happening. It wasnt behaving like this in .net 1.1.In .net 1.1 it would delete the text and only when the focus is back on the base window, hitting Delete would call the event.How do i control such a behavior? Is there some property that i need to set for property grid in .net 3.5 to prevent base window events from firing till the time focus is on property grid form?

Passing A Value To A Minimized Form?

Oct 17, 2009

I have a 2nd form that is minimized to the taskbar, I can click on the tab and the form opens and shows all of the data fine, but

From the main form, I am maximizing the second form and trying to pass a value to a toolstrip textbox on the second form then press a button on the toolstrip from the second form, I can get this to work fine, but where I am having a problem is

The button searches through a treeview, when I step through my code, I can see the value that I am passing, my code does execute, but the treeview is showing no nodes(but they are really there). At the begining of the code, I put a message box to give me a count of the nodes in the treeview, it shows 0, but I can see all 10000+ nodes. What the textbox is on the toolstrip is a search box. When the form is maximized, I can enter whatever and it finds it with no problems, but if I pass a value it doesnt find anything because the treeview is saying there are no nodes when there is.

Prevent A Form From Being Minimized?

Sep 12, 2011

I've got this little 'Sticky Notes' type of application and the form I have is a borderless, taskbarless form and for Windows 2000 compatability I'm using VS 2008 and targeting the 2.0 framework. One of the hurdles I have is that in XP, Vista & 7 when you click the Show Desktop button all of my note's windows get minimized and without a taskbar icon, it's not easy to get them back (at least not for a normal user) & I'm looking for a way to either right after the windows minimize I just have them all show again or if I can skip the minimizing message in the wndproc altogether

I've put together a test app that'll show the messages in a listbox for the form, but I'm not sure how to go about skipping sending the message to the form's base class. Here's a snippet, listMessages is the listbox on the form[code]...
