Pelles C Wiki

author_information

2008-06-07T13:40:19+02:00

* This wiki is planned as a multilingual wiki, that means, every language has an own namespace. E.g., the german version of this page has the name de:author_information, while the english one is only author_information, withount the “en”, because english is the default language. * I decided to use Dokuwiki, because it is much faster than other wikis and is especially designed for documentations. You can find informations about Dokuwiki here and about the syntax here.

available_drives

2011-11-22T10:25:52+02:00

This code snippet is originally from the former WinAPI site www.winapi.net Sometimes you need to know about all logical drives. The WinAPI gives us for that the function GetLogicalDrives(). It returns a bit mask which has to be analysed. Here is an example how:

center_window

2011-11-22T10:25:55+02:00

It looks sometimes much better, if a new modal dialog or window is centered to his parent. This function solves this for you. just call CenterWindow (hwndChild, hwndParent);. BOOL CenterWindow(HWND hwndChild, HWND hwndParent) { RECT rcChild, rcParent; int cxChild, cyChild, cxParent, cyParent; int cxScreen, cyScreen, xNew, yNew; HDC hdc; GetWindowRect(hwndChild, &rcChild); cxChild = rcChild.right - rcChild.left; cyChild = rcChild.bottom - rcChild.top; …

change_fileattributes

2008-06-09T12:37:23+02:00

This code snippet is originally from the former WinAPI site www.winapi.net Sometimes you need to change the file attributes, e.g. if you want to delete a write-protected file. This function solves this problem: #include SetFileAttributes (TEXT("C:\\filename.txt"), FILE_ATTRIBUTE_NORMAL);

check_directory_existence

2008-06-10T23:04:25+02:00

The following code checks for the existence of a directory on the filesystem. #define WIN32_LEAN_AND_MEAN #include #ifndef INVALID_FILE_ATTRIBUTES #define INVALID_FILE_ATTRIBUTES ((DWORD)-1) #endif /* Returns TRUE if filename parameter is a directory or FALSE if filename is either NULL or a file */ BOOL IsDir(const char *filename) { DWORD dwAttrs; dwAttrs = GetFileAttributes(filename); if (dwAttrs == INVALID_FILE_ATTRIBUTES) return FALSE; return (BOOL) (dwAttrs …

check_file_existence

2008-06-10T23:05:18+02:00

The following function checks if a file exists. #define WIN32_LEAN_AND_MEAN #include #ifndef INVALID_FILE_ATTRIBUTES #define INVALID_FILE_ATTRIBUTES ((DWORD)-1) #endif /* Returns TRUE if filename is a file or FALSE if filename is either NULL, empty or it's a directory */ BOOL IsFile(const char *filename) { DWORD dRet; if (!filename || filename[0] == '\0') return FALSE; dRet = GetFileAttributes(filename); if (dRet == INVALID_FILE_ATTRIBUTES) return FALSE; ret…

check_medium

2008-06-09T12:29:05+02:00

This code snippet is originally from the former WinAPI site www.winapi.net If you want to know, if the user inserted a medium like a disk or a CD into the drive, use this code: #include #include // uDrive: // 0 - A:\ // 1 - B:\ // 2 - C:\ // etc. BOOL IsDriveReady(UINT uDrive) { TCHAR szRootPathName[32]; UINT uErrorMode; BOOL bRet; PathBuildRoot(szRootPathName, uDrive); uErrorMode = SetErrorMode(SEM_FAILCRITICALERRORS); bRet = GetVolumeInform…

data_grid

2008-09-19T01:09:38+02:00

--- David MacDermot 2008/09/17 19:55 This article describes how to create a custom control in Pelles C. The control in this case is a data grid like component using a listview and an edit box along with a number of customizations to enhance the appearance of the control.

dialog_with_link

2008-06-09T12:45:07+02:00

This code snippet is originally from the former WinAPI site www.winapi.net To create a link within a dialog box, you have to add a Text to your dialog, which should be used as link. Assign the Notify-Style to this text control. We use the Name IDC_URL for this control.
