Cancel Fires But Other Code Also Fires When A Click Event Occurs?
Mar 9, 2012A form has many buttons. One of those buttons contains code to update the TableAdapterManager. One of the many TextBox controls has code in a Validating event handler. There is code to make sure a US phone number is formatted properly.If the user tabs out of the TextBox the Validating code works perfectly and show a message to the user if the phone number is not properly formatted and the focus is place in the offending TextBox.If the user clicks on a button that has code to update the TableAdapterManager the Validating code fires but instead of focus remaining on the offending TextBox, the code in the button Click handler also fires.
I would like to stop the button code from firing.Here is the code for the Validating event of the TextBox:
Private Sub TextBoxPrimaryPhone_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBoxPrimaryPhone.Validating
' Make sure the phone is formatted correctly.
[code]....
What additional coding to I need to include so focus remains on the TextBox?

VS 2008 Call Sub AFTER DocumentCompleted?
Apr 2, 2010I currently have two subs in Webbrowser3.DocumentCompleted. The first sub scrolls the web page to a specific point. The second sub takes a screenshot of the webbrowser window.Problem: Screenshot image is recording the top edge of the webbrowser. This means it is not scrolling to the right position before snapping the screenshot.
My guess is that the web page is not fully loaded when DocumentCompleted is called. Or the scroll is not being completed til after the screenshot has been taken. Result: After this is run, I end up with an image of the top edge of the browser. The Webbrowser is scrolled to the right place, but the image is taken before it gets there.

.NET WebBrowser Control's DocumentCompleted Event Passes No PDisp Argument?
Sep 6, 2011I have some experience developing for VBA inside Office apps, but I am quite new to VB.NET, and I just noticed that its WebBrowser control is a bit different from that one I used to reference via ShDocVw to use in my VBA Forms.ShDocVw.WebBrowser had the DocumentComplete event, which passed these arguments: URL as string and pDisp as object..NET WebBrowser has the DocumentCompleted event, in which i successfully found e.URL.ToString, but I couldn't find nothing similar to the pDisp object.
This is critical to me on migrating my project from VBA to VB.NET, for I need to handle particular IFrames when they complete loading, which I only could do by getting pDisp's document property. So I need help on learning how to do the same thing with this .NET WebBrowser control, and/or how to reference and use good ole ShDocVw.WebBroser in my Visual Studio project, to embed it in my forms.
Combo Box Fires Twice?
Nov 17, 2010I am using a combo box on a form in vb net 2008. I would like the user to be able to either tab to the control and then select an
item OR the user could click on the combo box and then select the item.
unfortunately it fires twice when the user clicks on the control. This is before any items are selected. I have tried placing it in mouse down , focus , key down etc etc.
It does not fire twice for the enter event so I tried to use that alone, but then there is no dropping down of the combo box when the user clicks on the control. Is there a way to release the combo box enter event on the mouse click event?

Deactivate Fires On Me.Show?
Jan 25, 2010I am trying to create a winform that will allow me to close when the form either loses focus or deavtivate. When I do Me.Show, it will call the deactivate? Is that right or is weird? The way took it was it fires when it either looses focus or is no longer the active form.
Also it seem like I have to click the form in order for it to work right. I tried Me.focus and that does work the way I expected.
Event In The DS That Fires When Data Changes?
Oct 13, 2010I read data into a DS from an XML file. The user has the ability to "Save" or "Save As" at any time. They can also "Open" an existing file or create a "New" one. (brilliant, don't you think?)
I need to make sure I ask the user if they want to save their existing data (i.e. rewrite the XML file) if the DS has changed from the XML load or from the last time they Saved. On Open, New or exit I have been checking the HasChanges function on the DS. This doesn't work the way that I need. I use AcceptChanges throughout the program to commit values to the DS. This appears to kill the HasChanges even though the DS is now different than the XML file.
Is there an event in the DS that fires when data changes? If so, I believe I can set a flag that can be checked later. If not, is there any other way to track that a DS has changed after the initial XML load? Would reloading the XML into a cloned DS and comparing the two work? Seems like a waste of "time", especially with large XML files, but if it's the only way.

View 4 RepliesWebbrowser Click Fires Twice
Dec 4, 2009In VS2005 I am using click on some elements in a webbrowser document to perform certain functions, eg print or open MS Paint but for some reason all the mouse events fire twice. A second click on the same element might be intentional so I can't just bypass code if the ID is the same as last time. There are no other calls of Document_Click anywhere in the project.[code]I supposes I could stick a timer on it and ignore any within 1s say but cheers for any more elegant solutions.

Mar 19, 2009I have an update statement under RowLeave event of my datagridview. Before I update it I need to validate the cell if there is an empty value.

Asp.net - ItemCommand Fires Before ItemDataBound On PostBack?

View 3 RepliesHomework - Test Fires The Message Box Twice?
Sep 20, 2011I am trying to unit test for data being input into a textbox (txtPrice). If it is not numeric, it throws a messagebox stating that the input must be numeric. However, when I unit test, I can't figure out why my test fires the message box twice.THis is my (simple) unit test:
Public Sub txtBoxes_LeaveTest()
Dim target As frmEstimate_Accessor = New frmEstimate_Accessor ' TODO: Initialize to an appropriate value
Dim sender As Object = Nothing ' TODO: Initialize to an appropriate value[code].....
My understanding is that for unit testing, you declare the sender, and (in this case) set the sender to some value that will trip the message box. 112L should do this on the leave event. I then write my expected, which in this case is 112L, fire the event, and then get the actual out of the text box. I then Assert.AreEqual to ensure the expected and actual are the same.

Timer Only Fires 8 Times Then Stops?
Mar 23, 2011I've been trying to get a Timer to execute code every 50ms and it's worked okay, but for some reason after doing the code 8 times (i.e. for 400ms) it just stops. As in, won't execute the code any more times. Specifically, it's wired up to an animation (Picture) and a rectangle which moves around the screen (Box). why the timer would suddenly stop executing after doing so for a while? It's the same duration every time.

DotNetNuke Module Page Load Fires Twice
Jul 11, 2011My module's Page_Load event is firing twice for each "actual" load. On the initial load both loads' Page.IsPostBack property is false.I've renamed Page_Load to Module_Load to verify the name wasn't an issue. I've made sure the method isn't handling both Me.Load and MyBase.Load, which has been the case in the past.The only thing I'm doing out of the ordinary is that my module is inheriting from an intermediate base class. Could this be the culprit? [code]I had an Image without an ImageUrl. Presumably this is set by my CollapsiblePanelExtender but rendered with a blank src.

View 1 RepliesEvent That Fires Only When User Moves The Splitter?
Jul 7, 2010I have a VB .NET form with a splitter control on it, and I want to save its position between program runs. I am currently handling the SplitterMoved event and storing the SplitterDistance. Then on program startup, I set the SplitterDistance to the saved value.
However, sometimes the program resizes the splitter, raising the SplitterMoved event and overwriting my saved distance. I have several splitters over multiple tabs in a tab control, and any time the user goes to a new tab for the first time, the SplitterMoved event fires.Is there an event I can use that will only fire when the user moves the splitter, and not when the program moves the splitter? I tried MouseUp, but when that event fires, the new SplitterDistance is not yet set.
Jquery - Delay A ASP.NET AutoPostBack So JavaScript Fires First?
Mar 2, 2010I've got an odd situation with a text box and an autocomplete setup on my page. I'm using a JQuery based autocomplete on a text box that has AutoPostBack="True". This works perfect if I use the keyboard to select an autocomplete item, which then fires Jquery to fill in the text box, and then when I tab out of the box the AutoPostBack fires. If, however, I click on an autocomplete item, my text box loses focus first and the AutoPostBack fires before the Jquery has a chance to change the text in my text box. Is there a way to delay either the PostBack or the Jquery so that they don't fight each other? I'm thinking it may have to be the PostBack that gets changed, since the JQuery would lose it's state on the PostBack.
