Hi Steve,

we have C ADK, which have C functions.
So I think yes.

Please notice that our vcomponents folder contains 4 dlls.

VReport.dll depends on VKernel.dll and VShared.dll

Do you have a function reference for the *.dll files?

I can't seem to find any help documentation on your website that pertains to the C ADK.

Hi Steve,

we have in WIKI description of general API ADK => https://goo.gl/EnygqA

For C usage, it is easy to see in the headers of C ADK that we use names as VProject_open() for functions to simulate OO instead VProject.open()

Also please check in C ADK folder Examples / Reports

Also we have
- tutorials about reports - how to design them in Valentina Studio - Report Editor,
- video lessons,
- online report examples

Hi Ruslan,

On your website I went to Developer->Reports for Applications->Download

I downloaded and installed 'Components for C 8.0' but I can not find any examples.
They have not been copied to the 'My Documents' folder as the readme file suggests they should.

My Documents/Paradigma Software only contains a folder named VCDK_x64_8

and within that folder are just the following two files:

EULA_ADK.txt
ReadMe_ADK.txt

OK, I've used PureBasic to list all the functions in vcsdk_release_x64.dll and I can see the equivalent functions that I'm familiar with from when I've used Valentina with Xojo: Project_Open, Report_PrintToDisk, etc... so that's a promising start.

Do the C commands that receive string parameters expect to get a pointer to a null terminated UTF8 string?

Thanks Ruslan,

The free version of Valentina Studio doesn't allow me to save reports, could I get a *.vsp file with a helloworld report in it (just a report with a 'Hello, World!" label on it) so I can test opening it and outputting it to disk from the C ADK?

Hi Steve,

really VCSDK do not contains Examples folder.

Please download also C++ VSDK archive for your OS, it has that examples.
and you can find there EXamples / vReports example with .vsp
This .vsp present in each ADK.

You can open it by free Vstudio and play with preview.
You can check .cpp file to see C++ code to work with this example.


2) TIP described in our WIKI page about How test VStudio PRO features:

- it is possible to use free Valentina Server, and then free Valentina Studio can create a new .vsp on that VServer, so any ADK can play with that .vsp. This project will alive until VServer restart.

Hi Ruslan,

I have downloaded and installed the C++ SDK, that has installed the Examples folder in My Documents but there is still no *.vsp file.

I have used Windows Explorer to perform a search of all folders and subfolders to be sure and it found nothing.

I have now installed the C ADK on Ubuntu but I can not find the Linux equivalent to vcsdk_release_x64.dll

I've found all the other vcomponents in /usr/local/lib but that key library is missing. I've used the locate command but no luck again.

It really shouldn't be this frustrating to try out your ADKs


Edit:
OK, I think I've found it, is it named libVCSDK.so rather than libvcsdk_release_x64.so?

Unfortunately if that is it I don't seem to be able to read the functions within it using PureBasic.

I initially had the same problem with the Windows version but I put all the vcomponents in the same folder and then PureBasic could read the library functions from vcsdk_release_x64.dll. Unfortunately the same trick doesn't work on Linux so I'm guessing there's still something missing.

Sadly I think I'm going to have to give up on this...

Hello Steve,

Yes, it is libVCSDK.so

I've rechecked the VCSDK project on Linux and found a possible reason why it can't be loaded.

Could you please add your PureBasic example, so I'll be able to rebuild the VCSDK library and check it?

Hi Sergey,

Thanks for your help.

Here is the PureBasic code:

nRes = OpenLibrary(#PB_Any,"libVCSDK.so")

If nRes = 0

  Debug "Could not open library"

Else

  If ExamineLibraryFunctions(nRes)

    While NextLibraryFunction()

      Debug LibraryFunctionName()

    Wend

  Else

    Debug "Could not extract function names"

  EndIf

EndIf

You can download the demo version of PureBasic here.

Hi Steve,

Thank you.
After fixing the issue I was able to load the library in PureBasic on Linux.

I'll make an example of how to work with reports with the description in our wiki.
And there will be a new build.

Haven't you tried to work with VCSDK and reports on Windows? Meanwhile, you can play with them.

Thanks Sergey,

Would it also be possible to get a 'Hello, World!' *.vsp file as I outlined in post #7 of this thread?
I did download the C++ ADK as Ruslan suggested but there was no *.vsp included with that either.

I did a partial test of the VCSDK on Windows. As the demo version of Valentina Studio wont allow me to save a report all I was able to do was open my test.vsp and confirm Project_GetReportCount() equalled zero.

Attached the example from V4RB with the SQLite database.
The query for reports is SELECT * FROM T1

Thanks Sergey,

I just made a quick test and I'm pleased to say I can open a project, run a report and save it to a file

Thank you, and now it works in my development build of VCSDK on Linux.
There was one more issue - in the next build, you'll be able to call just the Valentina_InitReports, without Valentina_Init.

Thanks Sergey,

Will you post back when the new Linux build is available for download?

Yes, we'll let you know when it will be ready.

Hello Steve,

The version 8.0.2 is available for download
