View 2 RepliesStopping Function On Event In .net?
May 18, 2010I have a vb.net application which does some processing. This processing can take a while. The application doesn't respond until the processing has ended and then it handle all events (such as click on buttons) that the user has done during the processing. I'd like to add a "Stop" button so that the user can stop the processing at some point. How can I do that? Could threading the processing (which is done in a function of the application) be a possible solution?
I tried to add a button which change a boolean value and putting the code of the processing function inside a while statement based on that boolean value. However it doesn't work because the click event on the button is processed only after the end of the processing.
Assign A Function To Their Click Event?
Oct 9, 2010I have a list of buttons in VB2010.What is the best way to assign a function to their click event.So every button has the same function, e.g.:
On Button Click
FireFunction(1)
End On Button Click
Without having to add a click event for every button.The goal is to produce something similar to what is done with the Control Array idea in Visual Basic 2006.
Run A Final Function Vb After Postback Event?
Apr 24, 2012I have a system that has a gridview on one page with an Update Panel. On selection of one row of a gridview the system posts-back using that CommandName and CommandArgument to post the row that is selected, and then set a Session variable as the ID of that posted selected row. The other controls run Async correctly and the button in question is already registered using this on the RowDataBound event.
Dim gvRowSelect As GridViewRow = e.Row
Dim imbSelect As ImageButton = DirectCast(gvRowSelect.FindControl("imbSelect"), ImageButton)
ScriptManager.GetCurrent(Page).RegisterPostBackControl(imbSelect)
I would like to try and get this session on the button command and somehow within the master page, set a label to the current Session. On the imbSelect command the code is:
Dim cellSnapshot As TableCell = gvSnapshots.Rows(e.CommandArgument).Cells(0)
Session("Snapshot") = cellSnapshot.Text
Within the masterpage is there anyway of calling a function after the Page_Load, and after it has resolved all Postback events?
Change A Sub To Function?
Mar 6, 2010If I change a subroutine to a function, do I need to change codes that call the subroutine? For example, I have subroutine : Public Sub fillDropDownList(ByRef ddlPage as DropDownList). I need to do unit testing on it, so I changed it to a function: Public Function fillDropDownList(ByRef ddlPage as dropDownList) As DropDownList. Some of my webpages called this sub like this:
Dim cCommon As New
cAdminCommon
cCommon.FillPageDropDown(ddlPage)
ddlPage.SelectedValue = 100
Do I need make change on the call?

Asp.net - Call A Code Behind Function From A Div Onclick Event?
May 15, 2012I have a bunch of divs on my page that are added at run time dynamically. When any of the dynamically added divs are clicked - All need to call the same function in my code behind. Each of the divs must pass it's own ID to the function. I can't use web methods as the function needs to identify which div was clicked and then show/hide/populate other controls on the page.

Calling Function To Update Value On Trigger Of Event
Nov 8, 2010I think I have a timing issue. On the trigger of an event I call a function to update a value:
Private Sub t0_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles t0.Click
Input.ppProperty = "blank"
UpdateRecord("Hey", Input.ppProperty)
MsgBox(Input.ppProperty)
End Sub
[Code] .....
Notice the difference, the property does not update until the function is completely finished.

Call A Function On CD Change?
Jan 26, 2010I've got a program that has a text box with a list of files that are on any removable media. Suppose you launch the program and there's nothing in your CD-ROM drive. Right now, you'd get nothing, and you'd have to insert a disc and click a "refresh" button, which triggers a function that repopulates the list.
Is there any good way to call this function on the event that the user inserts/removes a CD-ROM from any CD-ROM drive? Also, inserting/removing external disks and flash drives? Without having to constantly poll the drives. Floppy disks aren't important to me.

Forms :: Button.Click Event Inside A Function
Dec 13, 2010I created a function that retrieves information on which checkboxes are checked. It returns an array which the information coupled to the checking of those checkboxes. Those checkboxes and the matching textboxes are dynamically created at runtime in that same function. I'm pausing the application to wait for a button to be pressed. I'm trying to find a way to use btnDone.Click event directly because the code always reloops my function once more recreating the controls.
Public Function GetArray(ByVal strDLFolder As String) As Array
If blnDone = False Then
Me.Show()
[CODE]..........
Right now I'm setting a create a boolean switch when btnSubDone is clicked. What I would like is for something along the lines of:

Is it possible to use events like this? If not is there a cleaner way for pausing the application to wait for a button click (one that doesn't run the entire function again)?

Prevent A Sub / Function From Firing Multiple Times On The Same Event?
Apr 1, 2009I'm trying to prevent a sub / function from firing multiple times on the same event.My app is for handling inbound phone calls (tapi).The app is supposed to route calls based on the callerid number.
aircode below:
Code:
Private Sub OnNewCall(ByVal sender As Object, ByVal e As NewCallEventArgs) Handles tapiManager.NewCall
if newcall.callerid = "5551001" then
redirect(newcall)
[code]....
If callA.callerid = "5551001" then redirect(callA)but, once it is redirected to the new extension, do not then grab the call from the new extension and try to redirect again (resulting in infinite loop).I realize I could use an integer as a counter, but the problem is, I might actually get more than 1 call at the same time from the same callerid number. And, all the calls would need to be redirected (once).the calls do have properties like (which are unique identifiers to each call):
Code:
phcall.id and phcall.hashcode
I'm thinking I need to put that unique id into a temp var / array to run a check against to see if it has been redirected, if it has then skip, if it has not then redirect.The app would run 24x7, and I don't want the temp var / array to get too big, and would want to have it clean automatically (up on a timer maybe?)(I'm guessing it would be a dynamically growing array.)
Prevent Firing RowValidate/Validating Event Before A Function?
Apr 4, 2012I designed a DataGridView under the name "dgvTarifa" and took a chance on trying Row Validating (tried Validated, CellEnter, CellLeave, RowEnter, RowLeave all count same) event. The purpose of the code is to load the selected values of the respective columns into three textboxes in order to rephrase/revalue those and update them by pressing a button. All works fine every single line of code there's nothing wrong except one logical thing.
When the form loads the RowValidating automatically fires because I have a function that Selects the table from the Database and it fills the DataSet by then attaching it to the datasourse of the "dgvTarifa" table. After setting the datasource of the datagridview, it automatically jumps to the RowValidating event which I DONT WANT TO! It first has to finish the whole function and later when the user enters with mouse or enters/leaves a row this has to be fired. (eventually already have the CellClick event with the same code below so only RowValidating has to work properly...)
Here's the code I use at row validating
Code:
Private Sub dgvTarifa_RowValidating(sender As System.Object, e As System.Windows.Forms.DataGridViewCellCancelEventArgs) Handles dgvTarifa.RowValidating

Is this the right event I should be using? My other issue is that I don't know how to have the color dropdown re-populate for just the column and row I've selected. Here's my code so far for this event:

Is There A Record Change Event
Jun 9, 2011I am trying to calculate the 'Profit' field based on the current record's 'ProjectTotalBillingEstimate' field and the 'ProjectActualCost' field. I want the 'Profit' text field to be calculated every time a record is changed, either via the navigation toolbar or the Project ID drop down box. I tried performing the calculation everytime the 'Product ID' changed but then the values in the fields of the previous record were used. I was wondering if there was an event that I could use the would occur only after the entire contents of a record were loaded.Essentially what I need to happen is when one moves to another project record the profit field needs to be calculated only after all the fields update to the current record.

Dynamically Change The Function Of A Delegate In .NET?
Jun 18, 2009Suppose I have a class that represents a product to be priced using one of a number of different pricing strategies. This pricing occurs hundreds of times per second, so to eliminate repetitive if/else statements I am instead using a delegate to launch the appropriate strategy, like so:
Private Delegate Sub PricingModel(ByVal params As PricingParameters)
Private myPricingModel As PricingModel
Private myPricingParameters As PricingParameters[code].....
But this doesn't look right to me (though it seems to work). Is there an accepted/better way of doing this? Or is this the standard way? Or is this just simply a doomed approach from the start?
