Windows Forms General. Sign in to vote. Hello, I want to implement a multi threaded user interface but I have some problems. I have Form1 with a listbox, and a void that calls a web service for building a collection of objects that will be the datasource for the listbox. On Load event of Form1 I create a new thread that use this void. In the void I have an instruction that sets the datasource fot the listbox, but I recieve an error that tells me that the listbox control belongs to a different thread.

Can you give me some directions to solve this problem? For most applications it is just a gimmick, because users do not read very fast.

Most of the time it is better to design a different approach to showing logs, perhaps a stateful UI to let user choose what is interesting to him at the moment. You can have a look at their source code.

Handling user interface in a multi-threaded application or being forced to have a UI-only main thread Ask Question. Asked 11 years, 10 months ago. Active 11 years, 8 months ago.

I solved this problem by having a maximum size on the communication buffer, but then I run into a problem in the following situation: the main thread has to perform a complex action the main thread takes some parts of the action and let's separate threads execute this while the seperate threads are executing their logic, the main thread processes the results from the other threads and continues with its work if the other threads are finished Problem is that in this situation, if the other threads perform logging, there is no UI-message loop, and so the communication buffer is filled, but not emptied.

I see two solutions in solving this problem: require the main thread to do regular polling of the communication buffer only performing user interface logic in the main thread no other logic I think the second solution seems the best, but this may not that easy to introduce in a big application in my case it performs mathematical simulations.

I am able to create a multithred using afxbeginthread ,But each thread suppose to perform different task. Example : 1 insert the data into database and another one read the data from database.

Please give some examples. My vote of 5 zssure Aug It is useful for me to learn about the working threads and UI threads. My vote of 5 KirowOnet 5-Dec It works without dancing with a tambourine. Help: Creating a thread GC 9-Sep I have read through the various postings and tried to put some code together but it won't compile. I am trying to start the new thread from a menu item via a message handler based in my application's 'CView' based class.

Priority in Threading k. Now i am learning threading concepts. I executed following code segment in MFC Project. There is no error in program. It's executing but the output wrongly get stored in test. But it's not correctly working. I expected the output to print values in the file test. May u clearly give the definition of thread priority and how to use in my program to achieve the output what i expected Write strValue,strValue.

Member Inside the dll there a StartCapture funtion that creates a Audio capture graph by calling a BuildGraph funtion and then it starts a thread "CaptureThread". Now in my application i am calling an interface of my above COM Dll. So now ,if i call StartCapture from my application multiple times , will it create multiple CaptureThread and ProcessThread?

How ll it behave? I have not worked much with threading , so need help. I dont know how it works.
