Download Source Code and Example After answering a question on how to update an edit control inside a dialog from an action performed in another dialog, I remembered that I had implemented an owner-drawn seek button for a CD player application. As you held the button pressed, it incremented a value until you released the […]

This control contains two buttons. It’s very easy to use. Place a button control in your CDialog, add a CHiButton member variable (eg m_wndHiButton), and then in OnInitDialog subclass the control with m_wndHiButton.SubclassDlgItem(IDC_BUTTON1, this). To handle the message, it sufficient to add, using the class wizard, a handler for “on button click”. User can disinguish […]

 Download Source Code and Example The Windows Control Panel is the ideal way to allow a user to alter settings for an application that runs in the background, or automatically. But what are control panel applets and how do you write one? Well, after some exploring in the MSDN I discovered that control panel applets […]

A PS (Process Status) program for Windows 95 and Windows NT. This is a program to list all the active processes under Windows 95 or Windows NT. It lists each program’s full path name and Process ID. If you run it with no command line arguments, it displays the output on the console. If you […]

When trying to add registry functionality to a MFC application that I was developing, I looked up CReg* in the Win32 helpfile and sure enough found a CRegKey class. Great! Until you try and use this class in a non ATL (Active Template Library) application, as this code "depends" upon it. So I went looking […]

The registry is an ideal place to store information about your application. Using a key and a Value Name you can easily store and retrieve Value Data once you get a hang of the registry APIs. I recently encountered a scenario where I needed to store a list of strings in the registry. Typically, that […]

  Download Source Code and Example This subroutine handles GetDeviceType when you have an arbitrary path. There are three problems with the GetDeviceType API: (1) if you have a path which contains a file name, it returns the error code DRIVE_NO_ROOT_DIR; (2) it works differently on Windows NT and Windows 95; (3) if you pass […]

You can also read a related article in MSDN at http://www.microsoft.com/msdn/sdk/inetsdk/help/inet1560.htm Here’s what Roger had to say: Just followed the link on that page to the MSDN Inet article about COMCTL32. It looks like a good way also of telling the version. This article shows another method of testing – also I make use […]

CString source; //put your text in source if(OpenClipboard()) { HGLOBAL clipbuffer; char * buffer; EmptyClipboard(); clipbuffer = GlobalAlloc(GMEM_DDESHARE, source.GetLength()+1); buffer = (char*)GlobalLock(clipbuffer); strcpy(buffer, LPCSTR(source)); GlobalUnlock(clipbuffer); SetClipboardData(CF_TEXT,clipbuffer); CloseClipboard(); } How to get text off of the clipboard This is easy really but here it is for completeness char * buffer; if(OpenClipboard()) { buffer = (char*)GetClipboardData(CF_TEXT); //do […]

(1) If you don’t have OLE in your project already then add this #include < afxole.h > and do the following during initialization OleInitialize(NULL); (2) The following places a metafile copy of a view on the clipboard. It can be easily modified to work with any CWnd that draws to a CDC. void CMyView::OnEditCopyWmf() { […]

Introduction One of the intentions of the clipboard infrastructure in MS-Windows is to allow nearly seamless interaction between applications. However, neither Microsoft nor the reams of programming books available, seriously discuss […]

The code below is copying graphical data via enhanced meta file to any application. Even to WinWord 7.0 which makes it different to Randy Mores code. It is placed into an appropriate function of a class derived from CView. CMetaFileDC * m_pMetaDC = new CMetaFileDC(); m_pMetaDC->CreateEnhanced(GetDC(),NULL,NULL,”whatever”); //draw meta file //do what ever you want to […]
