So I'm building an app that uses win32's SendMessage as IPC. I'm using FindWindow to get the hWnd based on className and windowName. This has all being going fine and dandy until I want to talk to a root (as in child of the desktop) Window that has the same name / class name as other root Windows. Is there an alternative to FindWindow ...
I'm looking for the .NET-preferred way of performing the same type of thing that ShellExecute does in Win32 (opening, printing, etc. for arbitrary file types). I've been programming Windows for over 20 years, but I'm a complete newbie at .NET, so maybe I'm just looking in the wrong places. I'm currently using .NET 2.0 (VS C# 2005), but ...
I'm starting to create a proof of concept for an idea I have, and at this point, I need some guidance as to how I should begin. I need to sample the microphone input, and process that signal in real-time (think Auto-Tune, but working live), as opposed to "recording" for a while. What I'm doing is "kind of" a "mic input to MIDI converte...

What are the API calls to copy a file that is currently locked. I'm hoping to be able to use .Net, but Win32 calls would be fine as well. Please feel free to chime in about the same functionality on Unix, or any other OS. ...
I've created a DeskBand toolbar and I want to display a button on the toolbar that has the style visual style as a taskbar button.

Is there any way to remove the dotted line rectangle, which indicates the keyboard focus, on a Win32 common control, without owner draw or subclass them?

I am currently working on an MFC application that needs to be CPU-utilization aware. It may have multiple threads at different points in time, but the bulk of the work is accomplished by the main thread. I am trying to find a way to calculate how much percentage of the CPU this main thread utilizes. However, I am running into some prob...

I'm writing a program in C# that runs in the background and allows users to use a htokey to switch keyboard layouts in the active window. (Windows only supports CTRL+SHIFT & ALT+SHIFT) I'm using RegisterHotKey to catch the hotkey, & it's working fine. The problem is that I can't find any API to change the keyboard layout for the focus...
I am currently trying to create a win32 service using pywin32. My main point of reference has been this tutorial: http://code.activestate.com/recipes/551780/ What i don't understand is the initialization process, since the Daemon is never initialized directly by Daemon(), instead from my understanding its initialized by the following: ...
Hello everyone, There's a requirement that we will need to support querying a local SQL Server database for new data when the database is updated. Since these are external SQL Server databases, we may not be able to use SQL Server Notification Services nor can we make any changes to the database. My basic idea is to watch for data ...
I want to determine if a certain window is visible to the user or hidden/occluded. In Windows XP I would use the GetClipBox() function and check for a NULLREGION or empty RECT return value. This worked perfectly fine, but on Windows Vista it does not work if another window is occluding the window. In this case, GetClipBox() is returning ...

Hello Folks, I have a question regarding a symptom of my misuse of CreateProcess. I'm using the lpcommandline parameter to feed the path to my executable and parameters. My misuse is that I have not surrounded the path to the exe with quotes. My question is, why does the CreateProcess work just fine on most computers and not others?...
Am I safe in casting a C++ bool to a Windows API BOOL via this construct bool mybool = true; BOOL apiboolean = mybool ? TRUE : FALSE; I'd assume this is a yes because I don't see any obvious problems but I wanted to take a moment to ask only because this may be more subtle than it appears. Thanks to Dima for (gently) pointing out my...
