View 5 RepliesCall Event When Program Closes?
Jul 2, 2011I'm looking for a more elegant way to work around a problem I have
Code:
Private Sub MnuCheckForUpdates_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MnuCheckForUpdates.Click
Dim startInfo As New ProcessStartInfo(mStartUpPath & "" & "Updater.exe")
Process.Start(startInfo)
End Sub
As you can see I�m calling my updater program, but I want some code to run only after the Updater has closed.My work around was to:
A - Initially load the updater.
B � Start a time
C � Check if the updater is still running.
D � If its not call the routine in the timer event.
But this is not elegant is there another way around this, I can call events in the updater but I don�t think I can join them in someway to ProcessStartInfo Class .

Implement An Abstract Event In Program?
Jun 2, 2009I am trying to implement a service object class for the POS for .NET library using VB9. Specifically, the BillDispenser class. I define my class and inherit from Microsoft.PointOfService.BillDispenser. As normal, it creates stubs for all the MustOverride (abstract) properties and methods that I need to override (I love that), EXCEPT for the events. Apparently thare two events defined as abstract (MustOverride) in the POSCommon base class, but VB doesn't generate stubs for them.[code]...

Raise An Event On A New Thread In Program?

Obtain Event Arguments From Another Procedure In Program?
Oct 27, 2009This is a concept question about vidual basic asp coding -- I'm using certain examples, but the question is not about those examples specifically.
Let's say I have some code in button1_click vb code-behind.
In order to perform my desired function, I need access to StatusEventArguments in an event, for example, SqlDatasource_selected.
Is there a way to access that data from my procedure, or do I have to access it only in the event codebehind and store it in a global or session variable so I can access it in my button1_click procedure?
User Control Custom Event Program
Jan 16, 2010I had this new idea for a user control Sliding Bar/Panel. See screenshot. So I quickly whipped it up but I've got this problem that I cannot figure out why it does not work. Because I wanted to make it nice and tidy I desided to use a Class (Header) and created a TypeConverter (HeaderConverter)
Code:
Public Class HeaderConverter : Inherits ExpandableObjectConverter
Protected SortOrder() As String
Public Sub New()
SortOrder = New String() {"Text", "Depth"}
End Sub
[Code] .....
and goes to the RaiseEvent but nothing happens Why?
I know I could put properties on the Container control to access the ctnbutton Control that is embedded into the control but I thought this might be a nicer way.

Detecting When An External Program Ends To Start A New Event?
Apr 17, 2009I need to be able to detect when an external program closes so that I can start another event within VB 2005. I have tried to do this by monitoring the processes on my computer. The problem is that this programs comes up as some weird sub-process. It has an Image Name, which is indented from the other Image Names, and it shows that the User Name is the Administrator. This is the only information you can get from the Processes tab. There is a Task Name under the Applications tab, however. I was wondering if there was some code to monitor the Applications tab instead of the Processes or if there is yet another way to do this.

View 2 RepliesOverride An Event - TextChanged Event Not To Be Triggered When The CellClick Event Occurs?
Jul 20, 2010I'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?

View 2 RepliesMouse Click To Trigger An Event In Another Program Running Simultaneously
Mar 6, 2010I'm attempting to convert VB 5.0 source code to VB 2008. The converted code will then be slightly altered to facilitate its incorporation into a larger project that I'm developing in VB 2008. After using the conversion wizard (which is actually written for VB 6.0), I have 49 unresolved issues -- less than I expected. Much has changed since the days of my prowess as a programmer (Fortran in the 70's), so working my way through even as few as 49 issues will be a challenge, and will (no doubt) take me a while.
The UI for the VB 5.0 code I'm converting is a "virtual remote," with control buttons that (when clicked) trigger communication to a USB-connected device. With assistance, I've been able to develop my own "virtual remote," contained within my VB 2008 project. Eventually, I will "substitute" mine for the original. For now, though, I'm wanting to use MY "virtual remote" to trigger the original.
I have the executable for the VB 5.0 program, and can run it simultaneously with my "under-development" VB 2008 code. Problem is: I don't know how to cause a "click" on MY virtual remote to trigger a click on the original virtual remote (which is being "monitored" by the other program).
Raise Event When A Sql Database Connction Changes When A Console Program Runs?
Jul 27, 2011I have a VB 2008 console application .NET 3.5 who handles large data tables in a SQL 2005/8 database. Sometimes when SQL server do not response as application expect. Then SQL Connection change status from open. I try to get the event of changed connection string before error occurs.
1 - SQL Connection status changes from open to another status
2 - When this event fires a fix sub routine or function starts and fix the sql connection
3 - Return back where SQL Connection was when status was affected by program.
My app is a large list of SQL Commands who runs in a class orginsed as a simple list of sqlcommands.When a SQL Connection fails I will start at the last point in the program after SQL Connection are open again.
