Loadlibrary Error 126 Minecraft

to use a 3rd party dll in our main app. When I staticly link to the provided DLL it works ok and I can the DLLs exported functions. But we don't want our main app dependend on this dll on startup so I tried to dynamicly load the DLL when I need it : DLLHandle := LoadLibrary('3rdparty.dll'); ret := GetLastError(); if DLLHandle = 0 then begin err := SysErrorMessage(ret); Writeln(err); end //... loadlibrary error 14001 but did doesnt work : The LoadLibrary function returns 0 and the LastErrorcode is 3221225616. Because I don't know what I'm doing wrong I tried the same (on the same pc) coded in c and it works : but what doesn't it work with delphi ? : I call the same LoadLibrary function on the same dll! When I monitor with ProcMon I see that the 3rdparty dll gets loaded and that also the dependand dlls of the 3rdparty dll gets loaded. : So windows certainly finds the DLL. But somewhere it the loading process it fails : When I try to load the DLL with LoadLibraryEX with DONT_RESOLVE_DLL_REFERENCES or LOAD_LIBRARY_AS_DATAFILE it also works (but I can't offcourse call the needed functions...) I'm out of ideas : hope you guys can help me further... thx in adv.

Please tell me what I'm missing. Thanks, Fred EDIT: Launching the EXE via the IDE works with Delphi 7 !!

It's possible that D2009 is not searching the same folders for some reason. To make sure, you should get more details of the error, using something like... ShowMessage(SysErrorMessage(GetLastError)); Try (even temporarily) placing "oci.dll" in the same directory as you project's .EXE, and try again. Here are some things to check: Which directory is oci.dll located in? Is that directory included in the "PATH" environment variable? If not, try that. Have you maybe set an OVERRIDE for PATH in Delphi Tools/Options/Env variables screen? share|improve this answer edited Jan 12 '09 at 10:50 answered Jan 12 '09 at 9:50 Roddy 40.6k28124222 The directory where oci.dll is in the path, (system & user paths), and moving the dll is not an option to me –Fred Jan 12 '09 at 9:52 @Fred. Understood - but moving (or copying) the dll just temporarily will confirm that this is the problem. THEN we can look for the solution... –Roddy Jan

See more: C++ I tried to load a C++ DLL from a C++ application using LoadLibrary. I gave it the full path but it couldn't find the DLL (and obviously, the DLL is found where I said it is if a person looks for it using Windows Explorer). Eventually, the only way I got my application to find the said DLL was to put the application in the same folder as the DLL. So what's the point of writing the full path then!? How can this happen, and what can I do to solve this problem? I really would rather not have to put the application in the same folder as the DLL. [PS] Also, COM DLLs in the same folder as the DLL in question cannot find the DLL either. I suppose the COM doesn't have a strong enough idea as to where it is located with respect to other modules. [PPS] ...

From the author of  From the author of Delphi 6 Developer's Guide Learn More Buy From the author of From the author of  Delphi 6 Developer's Guide Learn More Buy Introduction Although loading DLLs implicitly is convenient, it isn't always the most desired method. Suppose you have a DLL that contains many routines. If it's likely that your application will never call any of the DLL's routines, it would be a waste of memory to load the DLL every time your application runs. This is especially true when using multiple DLLs with one application. Another example is when using DLLs as large objects: a standard list of functions that are implemented by multiple DLLs but do slightly different things, such as printer drivers and file format readers. In this situation, it would be beneficial to load the DLL when specifically requested to do so by the application. This is referred to as explicitly loading a DLL.
