Hi -- I have a C# application that basically has a button that executes a SQL Reader to loop thru a rather large resul set. Thru each interation of the reader object, I check to see if a file exists on the server. If it does, I update a textbox (multiline) with the missing file, update a status bar label, and a progressbar. Since this process is kind of lengthy, every 400 rows, I do a DoEvents() and TextBox.Refersh() to refresh the...

BackgroundWorker "Cross-thread operation not valid..."

by: Rob R. Ainscough | last post by:

I'm using a BackgroundWorker to perform a file download from an ftp site. Per good code design practices where I separate my UI code from my core logic code (in this case my Download file method in my FileIO class) I've established Public Event in my core logic classes along with RaiseEvents (that will updated a progress bar on the UI side). This all works great when I'm NOT using Threading (BackgroundWorker), however, as soon as I...

BackGroundWorker with Datalayer class. Reporting Progress.

by: Bob | last post by:

Hi, I am having trouble seeing how this bolts together. The UI starts a process which involves a long running database update. All Database activity is handled by a class called DT. DT has a progress event. So I added a bw to the form. The Dowork Calls a method which instantiates a DT and calls its Dataprocessing method.

BackgroundWorker not really workigng for me

by: =?Utf-8?B?SXNobWFlbA==?= | last post by:

Hi, I have a form with a progress bar on it and wanted to use the BackgroundWorker to be able to update the progress. I looked at examples, run some of them, but in debug, when the code gets to the do work method, it stops for a long while and then executes the first line of the method and the doesn't do anything else. What am i doing wrong?

Load secondary form in backgroundworker thread

by: RvGrah | last post by:

I'm completely new to using background threading, though I have downloaded and run through several samples and understood how they worked. My question is: I have an app whose primary form will almost always lead to the user opening a certain child window that's fairly resource intensive to load. Is it possible to load this form in a backgroundworker and then use the Show method and hide method as necessary? Anyone know of

Fire event in the same thread as the UI like BackgroundWorker

by: Sin Jeong-hun | last post by:

This is what I've always been wondered. Suppose I've created a class named Agent, and the Agent does some lengthy job. Of course I don't want to block the main window, so the Agent does the job in a separate thread. If the job is progressed it fires an event, and the main window handled the event by changing the value of a progress bar. The problem is that this event is fired in another thread so when the handler in the main window tries...

Can BackgroundWorker be Single Threaded Apartment?

by: =?Utf-8?B?SGFycnkgS2Vjaw==?= | last post by:

I have introduced a component to my solution that is throwing an exception about needing to be run in single threaded apartment mode. This component is created in an async call by a BackgroundWorker object, which seems to be on a MTA thread. Is there a way for me to get the BackgroundWorker thread to run in STA mode, or do I have to remove the BackgroundWorker and hand spin my own async call?

Problem With Comparison Operator <=> in G++

by: Oralloy | last post by:

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

The easy way to turn off automatic updates for Windows 10/11

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,...
