Hi all, I'm studying on a traffic simulation project right now. However i have problem with pausing the threads. Each car is considered as a thread in my app. When the simulation is running i want to pause it. Thread.suspend( ) method doesnt work, since i have to stop the thread from altering data. Let's say if there is a car on the road, and i click on pause button, the car should stay there.
Any ideas ?

Thanks in advance.

Gentle Advisors,
I have a form where a button selects an image and passes it on a control of this form and an other one.
I wanted to debug the statements but I got an error message at the source line

Code:

if (openFileDialog1.ShowDialog() == DialogResult.OK)

:

"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttrib ute marked on it....

Hi, I'd like to create thread wich call one function
this function takes a structure (2dArray) in its parameter and return another structure (Path).

the prototype looks like this :
Path function1 (2dArray);

I have problems because the threads parameters are (void *(void *)) and return void*

Hi!

I'm writing an application in which I'm copying a few files. It takes a while, that's why I would like to open a window which would say "Work in progress", so the user would know that copying is in progress and he should wait until it finishes. After finishing the copy-progress, the little notification window should close and let the user continue the work with the application.
I tried to solve this, but when I...

I'm using VC++ 2010 with Boost 1.43.
I've just created a class that uses winsock to handle network communication. Now there's a method called "fillQueue" which is defined like this:

Code:

void fillQueue(NetworkQueueTS& nq);

Problem is, the method enters an infinite while loop which fills the NetworkQueue with data. So it needs to be in an extra thread. The NetworkQueue class itself is already thread...

Hi

I'm trying out a simple threading application, wherein, I try to detect a list of Bluetooth users in the vicinity.

In its implementation, I've got a Swings form, which contains a 'Start' button and a TextArea.

On clicking 'Start', I look for the devices by calling a method detectData, which has an implementation of its own. When this happens, I ought to have a "Searching for devices..." message...

In vb2005, I have to load a treeview control while loading the form so make the form loading more effective therefore I use Background worker to populate treeview. I tried treeview to pass by ref and faced the error “Cross thread operation not valid: Control” accessed from a thread other than the thread it was created on..”, which makes sense.
Now I want to load treeview in background and return its object then assigning it : Is this...

I'm trying to setup a mechanism to read input from a source, but time out after 10 seconds of inactivity from that source. After the mechanism times out, I want to run some end processing on the input.

I have 2 classes:
1. Main thread.
2. Timer class.

Currently, the timer class times out like so:

Code:

public void timeout()
{
	System.err.println ("Output finished. terminating");

Hi guys,

I have a weird issue here. I'm writing an automated backup program that, well, performs automated backups of set folders to a set location. It has a GUI and a Windows service. The service has a timer (system.timer) that checks every 10 seconds whether a backup needs to be performed. If it does, it fires a method in a public static class to start the backup.

Now, this works fine on my PC, and on 2 other test...

Hello again, I would like to put my thread on hold and check the data that the threaded process' event passed to my other class. I am using suspend and resume methods, but the VS says they are obsolete. What should I do? Should I use Sleep with all the time incremental dynamic time slice or there are other ways?
Thanks, EARNEST.
