X Does Not Fire Closing / Closed Events
Mar 6, 2009I have a very simple app working well, problem is that it does not close properly. If the user uses the little "X" to close it, it still remains running, just becomes invisible. The X does not fire the closing/closed events..All I can figure out is that to get it to properly close I need to use "Me.Close()" with a button or menu item.I could remove the standard X and force them to use my own close button but that is rather silly..
View 1 RepliesAsp.net - Render .net Controls To String And Get Events To Fire
Jul 28, 2011I have this issue where I'm trying to generate HTML to display on the page that is coming from the database in form of a template that has different curly brackets that get replaced with dynamic content at run time. For example curly bracket {Content} gets replaced with a few checkboxlists, radiobuttonlists, textboxes and a submit button. The way I'm doing this is by creating controls dynamically and rendering them as string and then outputting that string to the browser. But what this does is, it doesn't recognise the events assigned to the controls when they are generated. I may be taking a wrong approach to the issue, but I don't really see how else this can be achieved. I have put up some sample code below to show what I'm trying to achieve.

View 4 RepliesDragEnter And DragDrop Events Fire Multiple Times In VB?
Jul 8, 2010I've got a research application that is hosting a webbrowser control and I'm implementing a feature that allows the user to select text from a web page and drag it to various research note fields. The issue I have is the dragenter and dragdrop events continue after the initial drop, inserting the text multiple times. Here's the test case on my box and the result.
Select Text in Browser Drag to Text Box Drop Text What happens is after the drop event is fired and the text inserted to the drop target, when you move the mouse after dropping the text, the drag enter event is fired, followed by the dragdrop event, then another dragenter and dragdrop. So, selected text such as "Selected Text" becomes "Selected TextSelected TextSelected Text".
Note: The dragenter event is properly raised once when the mouse enters the textbox, however the mouse does not have to leave the textbox after the dragdrop event fires. i thought there was something wrong with my application so I created a simple test app, containing a Webbrowser and a multi-line text box. This test app generates the same results and the code is below. This is the first time, I've implemented
drag and drop operations and I followed the guidelines noted in this MSDN article. While I did what the article suggests, I'm thinking I need to note the event was handled somewhere.

Mouse Movements To Fast To Fire Events Accurately?
Jul 8, 2011I'm working on a custom scroll bar. When dragging the slider, things work smoothing with what I have... that is if the users movements are smooth and slow-ish. When moving quickly the mouse move event doesn't seem to fire as accurately as I had hoped.. I attempted using the up and down buttons enter event for re positioning or "resetting" the slider whenragging is activated but still those events don't even fire when the mouse move event is firing. So I believe I hit a barrier of my .Net knowledge and hope someone here knows a way around this little issue.

SerialPort Events Won't Fire On Windows Server 2008 Using .NET 2.0 Application
Jul 9, 2010I have a program that reads data from a scanner via the serial port.This program works fine on Windows XP.We have a terminal server set up running Windows Server 2008.I run HyperTerminal on our test terminal, it connects and reads the scanner data fine through COM1.I run my app on that same test terminal and get nothing when I scan.My app connects to COM1 without errors and disconnects without errors.BUT, the DataRecieved event is NEVER getting fired.Neither is the ErrorReceived event.I have played with the Handshaking, with the RecievedBytesThreshhold and pretty much every setup setting I found.Set it up exactly like the settings on Hyperterminal.I have even tried starting a timer on a different thread to call ReadByte every second to try to KICK this thing into doing SOMETHING.Nothing has worked.
I have been trying to fix this for an entire day now.Added events to my class trying to see EVERYTHING that is going on. All I know is, it connects to the port and it disconnects from the port correctly but nothing happens in between.No data when I scan.No event fired at all between connecting to and disconnecting from the port.I have also downloaded other's simple serial communications applications.Nothing in .NET works.[code]

View 4 RepliesOpen A File And Change Stuff, Then Close It Without Saving The Changes, The Events Still Fire?
Mar 17, 2010I am using about 5 different filesystemwatcher routines total. I am using the following
filewatch.NotifyFilter = NotifyFilters.CreationTime Or NotifyFilters.LastWrite
AddHandler filewatch.Created, AddressOf addfile
AddHandler filewatch.Changed, AddressOf addfile
filewatch.EnableRaisingEvents = True
However, there is one problem with it... whenever I open a file and change stuff, then close it without saving the changes, the events still fire. I am opening excel workbooks in code, then use xlsWB.Close(SaveChanges:=False) to close them, and the event still fires, where the file isn't really changed so it should not fire.
Anyway To Stop Flow Of Events In .NET?
May 23, 2012that is a question I have been asking myself for a while.Giving a certain flow of events, can I when handling one of them, stop the next ones to be raised? For example, when collapsing a node which child was selected in a treeview (winform), the events are raised like that:[code]I could stop them by using a class member, but I was wondering whether there was a built-in function or just another way (a more elegant way) to achieve this, by acting directly on the events queue.

Pageload Dynamic DropDownlist?
Jul 29, 2007I have 2 dynamically created ddls in which the second ddl populates based on the first ddl and the values of both come from a database. These ddls are inserted into a table that is dynamically generated based on some event. My problem is that everytime I select a value in the first ddl, the page load event is called and I lose the table. Is there a way to NOT call the page load on a selection? Or is there a way to generate the table with the values of ddls as soon as the page loads. I tried to fix this problem

Calling A DropDownLIst's Selectedindexchange Event On Pageload?
Mar 4, 2009I have an ASP.NET 2.0 that contains a dropdown list used to filter records based on a group number. For example, if the dropdown list selectedvalue = 3, only records containing a 3 in the group number column of the table will display. This is working perfectly. However, when the page first displays the default value is 1, and the records from group 1 do NOT display unless I trigger the dropdown list event. I am trying to get the records to display for group 1 when the page first opens to avoid having to use the dropdown when the page loads. The "drop down list control" filters records in a "data list" control.
I am thinking of writing a piece of VB.NET code to automatically call the Drop Down List's SelectIndexChanged event on the page so the user does not have to do it. how do I call that event from the "On Page Load" or, is there a better way to do this?
Declare A Variable That Never Change From Pageload Until Close The Page?
Sep 15, 2009How to declare a variable that never change from pageload until i close the page. Simple Case :
* ShowInfo.PageLoad() begins to execute for UserA.
* ShowInfo.Page_Load() begins to execute for UserB
* UserA has variable Dummy = 100.
[code]....
But the Result: Since UserB's was the last one assigned to (which remember... there is only one version of this in all of memory), the Dummy Variable is assigned for both users but different session. UserB sees Dummy = 20 but UserA sees Dummy = 20 too. I Want that the result is UserA Dummy = 100 & UserB Dummy = 20?

VS 2010 : Use A Stop Button To Stop A Loop?
Dec 7, 2009I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.
