I'm developing this procedure using a timer object. The thing is the procedure is not in the timer's event procedure but I want it to depend on the timer's interval when executing, it's just not calling the timer procedure. How can u declare objects and use their event procedures in code.
View 2 RepliesUsing the visual part of VB I can create 'event' procedures. eg. if I double click on a button on the form it will take me to the code window and insert a procedure as follows:

View 18 RepliesI've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

I have a timer on a page in ASP.NET.
After a certain period of time elapses, I want to disable the timer.
I want to put a static variable in the timers tick event that will track how many seconds have elapsed.
My question is, will this work?
If user X and Y are viewing the page will they both have separate local static variables?
What is the best method of shutting down an ASP.NET timer after a certain elapsed time?
I have a windows application that need to process som quite time consuming jobs. In my first try i did all processing under
the form thread. The result was bad response and update of the form due to the heavy jobs.To get around the problem with bad response from the form i created a new class "processing" where i put all the data processing. Then i instanciated a background worker where i in the "doWork" sub created a new instance of "processing".The "processing" class creates a timer from system.timer, and the timer drives the processing.On the Timer event Elapsed the timer starts a new thread from the thread pool.
My problem is now when i want to asynchronously close the background worker (with the corresponding function call what ever it is called ...) there is still a timer thread out there that causes exceptions for me.
1. How can i close my background worker and at the same time have the timer to be stopped?
2. Is there a way to synchronize the timer event so that the timer executes from the background worker thread?
3. Is there a better approach for me to adapt?
I want to create an array of timer in vb.net. My problem is that how will i raise the tick event for a particular timer, say mytimer(x).tick and inside the tick event there is also a button, say mybutton(x) which changes location every interval. for example:
public class blah
dim mybuttons(20) as button
dim mytimer(20) as timer
private sub form_load(....) handles me.load
for x as integer = 0 to 20
[Code]...
i dont know what to do next, all i want is to pass the button mybuttons(x) to mytimer(x) tick event, in which their index number are the same. i want to create one timer per button. how to do that? please help me and post example codes. i've researched the net but i cant understand passing variables, addhandlers, etc. i'm just new to programming object oriented.

View 5 RepliesI am pretty new to VB and I am not sure why this is not working, basically I am trying to run a stored procedure from my web code. The sp runs just fine in SQL, I've tried it several times so I am sure that is not the problem. I don't want to return any results, I just want to see an "ok" statement if it runs and an error message if it doesn't. The code I am using for the lables (warnings and confirmation) is reused from earlier on the same page, the same goes for the validations (valUpload).

I've created an add-in for outlook 2010.I have a ribbon that has a button on it. When you click that button, I want it to call a procedure in the ThisAddIn.vb.There are two files: ThisAddin.vb and Ribbon.vb.I've tried several things to no avail. I've also set all the procedures to public.
Call Testing123()
Call ThisAddIn.Testing123()
Etc
How do I properly call this procedure?

View 3 RepliesI am trying to call the form_Keydown method from a procedure, CharacterJump()
Here is my
Keydown
frmGame_KeyDown(Nothing, New KeyEventArgs(Keys.Right))
What I am trying to do is after the user moves the character with the right arrow key and presses the up button to jump while still holding the right arrow key, the character will continue on moving, but the code that I put only does one movement and does not keep going.
Edit: I think I know the reason why it is only doing it once; it is because the keydown procedure is being called and therefore only executed once. The question is, how do I make it so it goes to keydown and doesn't return?
There are 2 forms open for the user in a school attendance program. The 1st. form is called FormBrowseClasses and the other form is called FormBrowseGrades. On the 2nd form is a procedure called PopulateTheDataGridWithData. That procedure loads data into a DataGrid.We would like to call PopulateTheDataGridWithData from within FormBrowseGrades so the data in the DataGrid will be refreshed.
We already tried:
' Refresh DataGrid data on FormBrowseClasses
'-------------------------------------------
objFormBrowseClasses.PopulateTheDataGridWithData()
but this only runs on a new instance of the form, not the currently open form. how to set this up correctly?

I created a Stored Procedure in the MS SQL 2008 database. Then i've added that SP into the Entity Framework model (you do not see it after opening the .edmx file, i see the SP when i open the model browser). Next i did an "Add function import..." . I did [Get Column Information] and "Create new complex type".
So now i'd like to use that SP. And using ExecuteStoreQuery seems the way to go.
The best attemp so far is this:
Function Index() As ViewResult

In my asp.net project, I have two particular aspx pages (lets say PageA.aspx and PageB.aspx)
In the codebehind PageA.aspx.vb, I want to call "Sub GetDefaultValues()" which happens to be in PageB.aspx

Is there a way to do that?
