Hello, I am having a problem in a large scale application that seems related to windows messaging on the Pocket PC. What I have is a PocketPC application written in c++. It has only one standard message loop. while (GetMessage (&msg, NULL, 0, 0)) { { TranslateMessage (&msg); DispatchMessage (&msg); } } We also have ...
We're developing a set of applications that need to communicate with each other on the user's session. These applications do not require any administrative privileges to run, but as soon as one of them tries to open an http listener - it fails due to lack of the administrative credentials. On the other hand, since user doesn't have any a...
I'm trying to get the examples of using ActiveQt working with my Qt Commercial 4.4.2 release (my commercial support expired). So far no luck. I keep getting "Failed to create component 'AxHost'". Sorry, not much to go on. My goal is to allow a client to use a widget from my app in their C# application. Am I taking the right approach...
Short of writing a function manually that translates a few known REFIID to names, such as: if (riid == IID_IUnknown) return "IUnknown"; if (riid == IID_IShellBrowser) return "IShellBrowser"; ...

I have a batch file that is located on one machine that I am invoking remotely from another machine. That batch file is pretty simple; all it does is set some environment variables and then executes an application - the application creates a command window and executes inside of it. The application it executes will run forever unless s...
Turns out there's a HKCR\Interface subtree where I can register my newly introduced COM interface. As I get it I would need it in two cases: if I want to enable marshalling - then I can register proxy/stub there if I want to publish more information on my component so that other developers could lookup the interface id and find it's hu...

I need to access a file concurrently with multiple threads. This needs to be done concurrently, without thread serialisation for performance reasons. The file in particular has been created with the 'temporary' file attribute that encourages windows to keep the file in the system cache. This means most of the time the file read wont go ...
I have inherited development of a Java/SWT application running on Windows only. One of the feature requests that I need to scope is a Google-chrome-type title bar in place of the SWT windows title bar. The application's tabs appear at the same level as the window control buttons. My understanding is that I will need to: write a Win...
It appears that specifying the KEY_WOW64_64KEY flag (reference) when accessing a registry key under 32-bit Windows XP has no effect - that is, no error is thrown, and the key is opened as if you hadn't had the flag set. I know Windows 2000 throws an error when it encounters this flag. I want to make sure my app is compatible with as ma...
I'm a longtime Visual Studio(from versions 6 to 2008) user that really like the editor and especially the debugger. Now I'm thinking of giving Linux a go, is there a IDE with similar, or better, capabilities out there? I'm also interested in recommendations for GUI libraries, c++ or c#. ...
How do I maximize the CPU usage for my application? I tried setting it to "Real-time" in the Task Manager, but there was no noticeable improvement - it's stuck at 50%. I'm working in Windows XP with Visual C++ 2005. ...
I'm debugging an intermittent problem in which an application (created using C++ in Visual Studio 2005) is faulting. The event log provides the following information: faulting module msvcr80.dll version 8.0.50727.1433 fault address 0x00008aa0 I did a Google search and found many other examples of applications crashing with this parti...

Suppose I have a GUI-only application that runs on Windows and I'd like to create a web interface for it using PHP. Is it even possible? I know I can use functions like system() or exec() to launch programs, but can I have more control over a running GUI app? Primarily, I would like to be able to send it keystrokes, so I can use it to pr...

When I save a file on a USB within my delphi application, how can I make sure the file is really (permanently) saved on the USB, when "Safely Remove Hardware" is not performed (especially forgotten to use)?

Reviewing our code I've found a curious definition in one of .idl files: [ object, uuid(uuidhere), dual, nonextensible, oleautomation, hidden ] interface IOurInterface : IUnknown { //methods here }; How can an interface derived directly from IUnknown possibly be a dual interface? Will anything break if I re...
