Re: [sqlite] Passing a path to sqlite3.exe to load a dll
Ah, you have missing dependancies. You need to make sure that the dependencies can be loaded. When Windows attempts to load the module all the dependencies must be loaded as well, otherwise the loader cannot return a handle to the loaded module. If no module handle is returned then the message "Module not found" is returned because sqlite3_load_extension does not actually check whether the module exists, but only whether or not it was loaded. So if the module exists and you get the message that it was not found, that is because it could not be loaded ... use depends.exe to see what other dll's are required and either put them on the path or in the same directory ... -- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. >-Original Message- >From: sqlite-users On >Behalf Of Jose Isaias Cabrera >Sent: Tuesday, 26 November, 2019 13:45 >To: SQLite mailing list >Subject: Re: [sqlite] Passing a path to sqlite3.exe to load a dll > >> >> > >Keith Medcalf, on Tuesday, November 26, 2019 03:38 PM, wrote... >> >> >> What is the canonical name of the file you are trying to load? > >c:\PMOProjects\libsqlite3decimal.dll > >As shown by the dir command, > >15:40:36.57>dir c:\PMOProjects\libsqlite3decimal.dll > Volume in drive C is Windows > Volume Serial Number is 40AA-E472 > > Directory of c:\PMOProjects > >11/26/2019 02:19 PM 225,376 libsqlite3decimal.dll > 1 File(s)225,376 bytes > 0 Dir(s) 431,761,633,280 bytes free > > >> It seems that you are being told that >"c:\PMOProjects\libsqlite3decimal.dll" does not exist. > >But it is there, > >15:40:48.95>dir c:\PMOProjects > Volume in drive C is Windows > Volume Serial Number is 40AA-E472 > > Directory of c:\PMOProjects > >11/26/2019 03:40 PM . >11/26/2019 03:40 PM .. >11/26/2019 02:19 PM 225,376 libsqlite3decimal.dll >11/25/2019 09:21 AM 3,446,300 PMOProjs.exe >11/22/2019 02:17 PM 926,748 PMOUpdater.exe >10/04/2019 11:30 AM 932,223 sqlite3.dll > 4 File(s) 5,530,647 bytes > 2 Dir(s) 431,760,363,520 bytes free > >15:43:18.90> > > >> Are you sure that the file exists and that you have permission to >read/execute it? > >Aaaah, permissions...

Re: [sqlite] Passing a path to sqlite3.exe to load a dll
What is the canonical name of the file you are trying to load? For example, if you are trying to load the file "jitterbug.dll" from the directory "c:\a\b\c" then the canonical filename is "c:\a\b\c\jitterbug.dll" It seems that you are being told that "c:\PMOProjects\libsqlite3decimal.dll" does not exist. Are you sure that the file exists and that you have permission to read/execute it? -- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. >-Original Message- >From: sqlite-users On >Behalf Of Jose Isaias Cabrera >Sent: Tuesday, 26 November, 2019 13:28 >To: SQLite mailing list >Subject: Re: [sqlite] Passing a path to sqlite3.exe to load a dll > > >Keith Medcalf, on Tuesday, November 26, 2019 02:57 PM, wrote... >> >> >> Escape the reverse solstice with a duplicate reverse solstice (\ -> \\) >or replace them >> with normal solstice (\ -> /) since Windows recognizes either as the >path separator. >> The CLI, like most things, parses escape sequences on input. >> >> Same applies to the C API function.

Re: [sqlite] Passing a path to sqlite3.exe to load a dll
Escape the reverse solstice with a duplicate reverse solstice (\ -> \\) or replace them with normal solstice (\ -> /) since Windows recognizes either as the path separator. The CLI, like most things, parses escape sequences on input. Same applies to the C API function. You specify the full path and name of the file. Since the compiler probably also parses escape sequences in its input, you probably need to escape your reverse solstice there as well. -- The fact that there's a Highway to Hell but only a Stairway to Heaven says a lot about anticipated traffic volume. >-Original Message- >From: sqlite-users On >Behalf Of Jose Isaias Cabrera >Sent: Tuesday, 26 November, 2019 12:35 >To: sqlite-users@mailinglists.sqlite.org >Subject: [sqlite] Passing a path to sqlite3.exe to load a dll > > >Greetings! > >I am trying to load a DLL to the DOS tool, but it's failing.
