Hi there,
Can anyone tell me why invoking a single SQL insert statement (well, rather,
a method that performs a SQL insert) using an asynchronous delegate should
result in twice the number of records being inserted? Am I just making a
mistake somewhere? (though I don't get double the records if I call the
method synchronously.)
Thanks,
Darryl

Hi,
I am working on a Windows-based client-server application. I am involved in
the development of the remote client modules. I am using asynchronous
delegates to obtain information from remote server and display this info on
the UI.
From doing some research, I know that the way my implementation works today
is not thread-safe, because essentially my worker thread updates the UI,
which is BAD. So, here I am trying to figure out how...

Hi There
This question is about calling an asynchronous web service from the UI
thread. Unless I am making a fundamental error, it appears that the
asynchronous web service call seems to spark off an
Application.DoEvents() when system resources are low and the message
loop has queued requests.
Here are some snippets of code to describe the problem:

Hi,
I've found what appears to be a bug with ASP.NET web service method
invocation - making it impossible to invoke and get the result of a
synchronous web call after an asynchronous call has been made if both are
using sessions.
Heres an example for two calls in the web service, the first is expected to
be executed asynchronously by the client and the second to get the progress
of the first while it is executing:

I have two different scenarios:
1. I have an application that calls a web service and passes an
object. Web Service takes that object and does some stuff with it, which
could take some time. It seems to me that in this case it would be
appropriate to use asynchronous web service. Am I correct?

In a newly created test app, to maximize client performance I tried to
make two SOAP method calls in tandem (the soap methods execute some
specified query), as each call includes a large amount of idle time by
the client as it waits for a query to execute and return a dataset.
As a test, I initially wrote two versions:
' // Sequential & Synchronous
Dim webobj As com.mycompany.webobject
Dim ds1 As System.Data.DataSet

I have a legacy application written in C that I'm trying to convert to
C#. It processes a very large amount of data from many clients
(actually, upstream servers - this is a mux) simultaneously.
I've read through what must be dozens of ways to do socket
communication in C#, and it seems they all devolve into three basic
options - Socket.Select, IOCP through a native interface, and
Asynchronous callbacks. I'm fine using Asynchronous...

Hi,
I have a stored procedure that I want to execute and then wait in a loop
showing a timer whilst it completes and then carry on once I get
notification that it has completed. The main reason for this being to stop
the user thinking the application has frozen when in fact it is just waiting
for a long SP to complete. Another reason for doing it like this is that I
also have had a problem in the past where the SP takes longer than the...

I need to perform Asynchronous Inserts using DAAB. So far I have a method
which does an insert but how can I do this Asyncronously so that it does not
affect the load on our public production website? This question is wide open
but make sure you give me some ideas in context with DAAB syntax. Some
thoughts are threading, ATLAS, etc. but I have no clue how to even approach
an Asynchronous Insert or any techniques at this point. Also, I...

i need to implement some asynchronous call to my com+ component, but i
need it to return some values (e.g. results of sql select statement).

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
