In the MEMORY_BASIC_INFORMATION structure one finds two PVOID variables, called BaseAddress and AllocationBaserespectively. I'm reading a book on Threading and its going over how to get the stackspace left on the stack in quite some detail, however there's something I'm not sure I understand correctly. The BaseAddress in the structure ...
I need to run a counter and a timer at the same time, but I'm not sure about how to achieve it. I have a batch file that counts the number of times any key is pressed in an easy loop made by a goto, once its done (keypress) for the first time, it fires a timer for 1 min; the key pressed in that time, must be stored in another variable...
OK, as I understand it, the .NET Threadpool maintains a number of background threads ready to be used for tasks of some kind. The Get/SetMinThreads and Get/SetMaxThreads methods contain two parameters that can be returned or adjusted. According to MSDN the two parameters indicate the number of worker threads and the number of threads ...
I have a C++/Qt QThread worker thread, which stores its current status as an ENUM (e.g. values such as Working, Finished). Only the worker thread sets the ENUM. I need to be able to read the status of the worker thread from another thread (the GUI thread), to display on the screen whether work is being done. Is it safe to read/write th...
I have a pool of threads which are working independently. Basically these threads are getting data from websites. I have also another thread which change my System IP.

I have a static class that holds a dictionary of objects. I have multiple threads that access this dictionary and create objects on it that are specific to that thread. How and when can I remove entries from the dictionary when a thread is "done"? Basically this is a static class for an ASP.NET application that all requests can have "is...

I have created three checkbox controls for three threads and each would start by checking a checkbox control. When a user unchecks a checkbox, I want to turn on the Wait Cursor on the other thread controls rather than completely disabling them for an instance of time, letting a particular thread to stop. How would you set a IDC_WAIT cur...
This is more a generic question than a specific one. I'm trying to have a multi threaded environment that stays active so that I can just submit tasks and run them. I want to do this without the hassle of executing in a web server or application server. The idea was to use a java thread pool for this, but the issue here is that the pool ...

Hi, I have a C# application that downloads a list of .xml files from an on-line data warehouse. This application dumps the files into a local directory and it takes roughly 1 hour before all 10k files have downloaded. This is a daily process. I need to take each of these files and extract, transform and load the contained data to a da...

Can you monitor SQL server to tell exactly what queries it is running? We have an application that is exhausting the application pool. A server administrator has sent us a report from Debug Diag [http://www.microsoft.com/downloads/details.aspx?FamilyID=28bd5941-c458-46f1-b24d-f60151d875a3&displaylang=en][1] which shows threads runni...
Is it safe to for example do: void AddTwo(int &num) { num +=2; } void ThreadProc(lpvoid arg) { AddTwo((int)arg); } Would it be safe for this to occur if 4 threads were doing this at the same time? Thanks ...
I've got a class that contains (among many other things) a list of items that needs to be saved to disk as often as realistically possible. In order to allow this, whenever any change is made, it uses a timer to delay saving to disk by half a second, and if any further changes happen within that half second, it delays the timer; in other...
Hi, Given the following code: ... private static SpinLock logLock = new SpinLock(false); ... private static void ThreadFunc() { bool lockTaken = false; logLock.Enter(ref lockTaken) { try { // do stuff with during an acquired SpinLock } finally { logLock.Exit()...
I have a method which, conceptually, looks something like: Object f(Object o1) { Object o2 = longProcess1(o1); Object o3 = longProcess2(o2); return longProcess3(o3); } Where the processes themselves might also be compound: Object longProcess1(Object o1) { Object o2 = longSubProcess1(o1); return longSubProcess2(o2)...
