Advanced Custom Studies DLL Loading Management

Based on user feedback in particular this thread: v2195 recompilation... And the fact that we have seen issues raised over time from custom studies developers with managing custom study DLLs for users with changing Sierra Chart versions that require custom study DLL updates, we realize we need to implement much more advanced loading of custom DLL studies. In the next release, Sierra Chart will support more advanced DLL loading management. This will be the format for a custom studies DLL file name: Example: [DLLName]_[optional_4_digit_numeric_version][optional _64 suffix].dll So you can install DLLs with different version numbers to match up with different Sierra Chart versions where there has been a change requiring an updated custom studies DLL built for that version or higher. Sierra Chart will then search for all of the different files which match to a particular DLLName and examine the internal version number (not the version in the file name) of these files and load the appropriate one based on the particular Sierra Chart version the user is running.

Regarding post #1, we have done another release, 2217. The four digit numeric version number can now be any length. It can be one digit or as many digits as you want. And since the internal version number of the DLL is what is used to determine what particular DLL to load, not this external version in the file name, it does not matter what the version number in the file name is. You can make that whatever you want for your own naming purposes. And it is optional. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

If there is any feedback about the functionality described in this thread, not working as expected we would like to know. Or if it is working well, it would be good to know that as well. We have only done basic testing. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.

Done one basic test yesterday and the bare filename without version number gets precedence in loading when compiled in a newer version. All I need to reduce the number of files that are managed in automated downloads. This will save me a lot of time at my next update cycle. Great job.

Hi SC, With version 2215, we have experienced the following : with only one DLL named "hello.dll", there is no issue and SC sees it i.e we can load the study via "Add Custom Study". Copying that same dll and naming the copy "hello_64.dll", we can load the "hello_64.dll" but cannot load the original one, "hello.dll", which is still in the data folder. Renaming the original one "hello_55.dll", i.e we now have "hello_55.dll" and "hello_64.dll", we can now load both. We are asking this question as compiling via SC gives a DLL with "_64" in the name but some in our group compile via Visual Studio, and didn't have that naming convention. Will you keep this new convention going forward please ? Or can you please make sure that we can keep loading two dlls, one with and one without "_XX" ? Many thanks. |

Fyi. You can set the output file in VS with any _XX or any other naming convention. Should not be an issue.

In the case of post #7, is one 32-bit and the other 64-bit: "hello_64.dll" "hello.dll" What is the purpose of having two DLLs? If they are both 64-bit and essentially the same what does it matter if only one can be used? Sierra Chart Support - Engineering Level Your definitive source for support.

No, both are 64 bit. What we wanted to point out is that if you have two DLLs, one named "X.dll" and the other "X_64.dll", then you cannot load "X.dll" following the change mentioned in this thread

Yes that is true. They will need to have some difference in the naming other than the _64 at the end.

i see problem now.Example/reproduction: 3 studies: x1, x2, x3, and now, 3 different DLLs include studies linked in DLL from 1 source path. 1.dll (x1, x2) 2.dll (x1, x3) 3.dll (x1, x2, x3) BUG/PROBLEM : Only one last build (date) DLL visable in Custom SC . If u build as last 1.dll u can not see studie x3 and 3.dll and 2.dll. Why im not use 3.dll only? Every Dll has diffrent user/premissions in Studies Access Control Panel.

I have other problem, can not load any DLL when SC is running. Example/reproduction: 1. move default UserContributedStudies_64.dll from SierraChart/data to SierraChart/data/tmp folder (this step is to skip error when SC block DLL for open, if "ALLOW DLLS Load" not works) 2. Start SC and open any Chart , select Study/Add Custom Study/ , normal is UserContributedStudies not visable . OK 3. Try to load DLL, Analysis > Builid Custom Studies DLL > Builid > Allow Load DLLs 4. Build > Realease Single DLL and Deny Load > Folder > data/tmp 5. select UserContributedStudies_64.dll and Click "open" Message Log Setting study DLL module function objects to indicate DLL is not loaded: C:\SierraChart\Data\tmp\UserContributedStudies.dll | 2021-01-21 22:55:17.887 Study DLL module not found for: C:\SierraChart\Data\tmp\UserContributedStudies.dll | 2021-01-21 22:55:17.887 Whats wrong? SC not run in Safe Mode. SC2222 Date Time Of Last Edit: 2021-01-21 22:38:12

As we look again at post #19, what is the problem? Of course you are going to get the error you are because you are trying to use a DLL from a location which is not supported. We are not understanding at all what the core problem is that you are having. We have not identified any problem. Sierra Chart Support - Engineering Level Your definitive source for support.

The Data Files Folder: General Settings Window: Data Files Folder (Global Settings >> General Settings >> Paths >> Files and Folder Paths) Test the latest prerelease. The folder is always now overridden in the case of custom study DLLs to be the Data Files Folder. One thing that we would like to do and eventually will get to, is to have a dedicated folder in Sierra Chart to contain DLLs. Additionally, if the DLL wants to load other dependencies in subfolders, then certainly we can support distribution to those subfolders of files, and the DLL can discover its own location through the operating system and then load the necessary dependency modules.
