I'm creating a custom control in wxWidgets that displays a menu as part of it, and currently working on the Windows side of things. wxWidgets doesn't have a way of setting the width of a menu. It just makes the window as wide as the longest string plus a few pixels on either side. In the API, there is a way to get the actual Windows A...

What is the best way to find out where is notepad.exe and mspaint.exe that will work across various versions of Windows? Should I get the Windows directory via SHGetFolderPath(NULL, CSIDL_WINDOWS, NULL, SHGFP_TYPE_CURRENT, dir), and then traverse through all the subdirectories to look for the two files? (Assume that I am not interested...
The environment is plain-old win32 under C/C++ without any fancy MFC or similar mumbo-jumbo. I have a window, which has several children and grandchildren. Some children are oddly-shaped icons, and I need them to have transparent background (oddly-shaped icons). Consider a this pseudo-structure: Parent1 Child1 (normal) Child2 (oddly-s...
I've got a window that I handle WM_NCLBUTTONUP messages, in order to handle clicks on custom buttons in the caption bar. This works great when the window is maximised, but when it's not, the WM_NCLBUTTONUP message never arrives! I do get a WM_NCLBUTTONDOWN message though. Strangely WM_NCLBUTTONUP does arrive if I click on the right of th...

I'm trying to use SendMessage to Notepad, so that I can insert written text without making Notepad the active window. I have done something like this in the past using SendText, but that required giving Notepad focus. Now, first I'm retrieving the Windows handle: Process[] processes = Process.GetProcessesByName("notepad"); Console.Wri...
In a previous question, I asked how to send text to Notepad. It helped me immensely. For part 2, here's a simplified version of the same applied mIRC: [DllImport("User32.dll", EntryPoint = "FindWindow")] public static extern IntPtr FindWindow(String lpClassName, String lpWindowName); [DllImport("user32.dll", EntryPoint = "FindWindowEx...

I'm using a CControlBar-derived class and I would like to detect when the docking state of the CControlBar has changed (i.e., docking from vertical to horizontal or when it goes into floating mode). Of course, I could handle WM_SIZE but it seems to be a waste of ressources doing the task every time a WM_SIZE message is fired instead of ...
Hi I want to get the icons of common file types in my dll. I am using vc++. I only have the file extension and mime type of the file based on which I want to get the icon for the file. Can someone please tell me how I can do that? (The method available in vc++ needs the user to give the path of the file for which the icon is needed. I ...
People always advised me that if I am doing some application that should use some Windows APIs to do any process level job, I must use VC++ and not any other .net language. Is there any truth in that? Can everything that can be done using VC++ be done in other .net languages also? Are all the .net languages the same when their capabil...
I wish to download a web page, which may be in any possible text encoding, and save it as UTF16LE. Assuming I can determine the text's encoding (by examining the HTTP header, HTML header, and/or BOM), how do I convert the text? I am using Delphi 2009. Unfortunately, the help files do not explain how to get from any encoding to a Unico...

I created an application in VS 2008 Express as an MFC app just to take advantage of the easy GUI creation. I might re-do this app in pure win32 since no other MFC classes are used (just a button and a text box, the button fires off the main program, all win32). My only question that determines whether I stay in MFC or port it over to pur...
