C# Equivalency of VB function "DoEvents"

Question

Basically the DoEvents function does something mainly used for waiting.
Here's an example:
Do Until Winsock1.State = 7
    DoEvents

Loop
That example waits for the winsock control to successfully connect. So how would I perform the same task in C#?
Thanks in advance

Answer 1

do
{
    DoEvents();
}
while(WinSock.State==7);

Answer 2

Edit: Nevermind figured it out. It's Application.DoEvents();
Thanks for the help =]

Answer 3

Does C# has On error resume next?

Answer 4

Something like this should do the trick.

for (int i=0; i<1000; i++) {
    try {
        // Do something here.
    } catch {
    }
}

Hey Tim J. Adams!

I really hope you don't find this offensive (if you do I'm terribly sorry, I know you ment well by answering the question that was posed), but check the dates before you answer a post

Answer 6

And for the record, we C Sharp guys do not use "On Error Goto", or any goto for that matter.

 

Answer 7

If you call DoEvents in your code, your application can handle the other events. ... Unlike Visual Basic 6.0,
application.DoEvents(); in c#

 Please chck : For  C#
                      For vb6.0

So i think it is not waiting for anything, It helps other control in a vb or c# forms to run. Otherwise if a time consuming job called ,the forms looks like not responding. to avoid this you can use DoEvents() method.

I will recommend

The BackgroundWorker class allows you to run an operation on a separate, dedicated thread. Time-consuming operations like downloads and database transactions can cause your user interface (UI) to seem as though it has stopped responding while they are running. When you want a responsive UI and you are faced with long delays associated with such operations, the BackgroundWorker class provides a convenient solution.

jannemanrobinson,

Remember that people come by these posts many months (& perhaps years) later to read these posts.  Nothing frustrates me more than to be googling for an answer, and find that someone had asked the same question & it was left hanging..

These forums will likely serve as a good resource for as long as C# remains an actively used language.  I have a feeling that these posts will be preserved somewhere, long after we are gone. (along with cigarrette TV commercials from the 50's!).

Answer 9

That's it. Ive read that post and solved a problem mine today, 2 years late. : )

Also is usefull to say that, sometimes, the Application class should get ambiguous with some

other libraries, like Microsoft.Office.Interop.Excel and etc... in these cases, we can specify the full path of

Windows Forms Application class, by typing System.Windows.Forms.Application.DoEvents();

Answer 10

I will recommend

The BackgroundWorker class

For the benefit of future seakers of solutions, this is the answer. The DoEvents method is not the best solution for C#. DoEvents is something that unmanaged VB programmers needed because it does not support multiple threads. A developer using managed code (and/or a language such as C++ that supports threads) should know how to use threads instead of DoEvents. DoEvents is convenient and can be used if a developer knows how to use threads such as what the BackgroundWorker class provides and understands the consequences.

Simple Samples,

The purpose of DoEvents is not really related to threads.

Its purpose is to allow Windows to interact with the form and its controls for things like Refresh() and Event-processing.  It also allows the screen to update and for the user to interact with parts of the form (such as buttons.)  One side-effect is that it can allow the user to click the exit button while a loop is processing and after exiting, the loop resumes processing, which may in turn re-load the form.
