Better managing icons files names
by Pedro Henrique Lara Campos 01 Jan '14

Can Wine or could it in newer versions, use a prefix for their icons, like wine_56BA_Tcharam.png, or maybe their own folder? My ~/.local/share/icons is like... full of bottles, every corner I look, I find an icon from wine :P

Hi, While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

Speaking of style, I'd probably remove all 'if (hr == S_OK)' check, it never fails, or reduced a scope of 'str'.

about eventlog

I examined the design of RegistereventSource(). The return value type is HANDLE,but the details of it is unknown. However,I suppose,the code should be like this(I'm not good at coding of Win32) /****************************************************************************** * RegisterEventSourceW [ADVAPI32.@] * * See RegisterEventSourceA. */ HANDLE WINAPI RegisterEventSourceW( LPCWSTR lpUNCServerName, LPCWSTR lpSourceName ) { int arg_length,path_length; LPDWORD existance; LPWSTR reg_fullpath; LPWSTR filename; LPDWORD lptype; LPWSTR lpdata,gldata; HKEY hkeyp; HANDLE eventhandle; int number_of_entry,length_of_dat; FIXME("(%s,%s): stub\n", debugstr_w(lpUNCServerName), debugstr_w(lpSourceName)); if(lpUNCServerName!=NULL) { FIXME("lpUNCServerName:%s\nExecution in another server is not suppported.", debugstr_w(lpUNCServerName)); } else { existance = NULL; number_of_entry = 0; length_of_dat = 0; filename = (LPWSTR)"Application";//FIXME:this should be all of sub keies. reg_fullpath = lstrcatW((LPWSTR)"System\\CurrentControlSet\\Sevices\\Eventlog\\Application\\",lpSourceName); arg_length = lstrlenW(lpSourceName); RegCreateKeyExW(HKEY_LOCAL_MACHINE,reg_fullpath,0, NULL,REG_OPTION_NON_VOLATILE,KEY_READ,NULL,&hkeyp,existance);//Create or open key. RegQueryInfoKeyW(hkeyp,NULL,0,NULL,NULL,NULL,NULL, (LPDWORD)number_of_entry,NULL,(LPDWORD)length_of_dat,NULL,NULL); if(length_of_dat<2 || number_of_entry<2)//Key entry is void. return NULL; *lptype=(REG_SZ); RegQueryValueExW(hkeyp,(LPWSTR)"EventMessageFile",NULL,lptype,(LPBYTE)lpdata,(LPDWORD)path_length); RegCloseKey(hkeyp); eventhandle = GlobalAlloc(GHND,(arg_length+path_length)*sizeof(LPWSTR)); gldata=(LPWSTR)GlobalLock(eventhandle); //After that,store data follows:filename,file path,source name;I do not know how to. if(eventhandle==INVALID_HANDLE_VALUE) { ERR_(eventlog)("%s\n", debugstr_w(lpUNCServerName)); return NULL; } } return eventhandle; }
