Ini file reader

[martinrame]

Hi, I need to add INI file reading support for an utility I'm creating, that uses dcmtk.

Before implementing it by myself, I would like to ask if the library has this feature already implemented.

Thanks in advance.

[Jörg Riesmeier]

What about OFConfigFile? It's probably not the best solution but it is used for the association negotion profiles in dcmnet and some dcmpstat tools.

[martinrame]

Thanks, let me try it.

[martinrame]

My .ini file contents is this:

Code: Select all

[default]
HttpPort=80
DicomPort=104

I'm trying to read it with this:

Code: Select all

  FILE *lFile = fopen("mycfgfile.ini", "rb");
  if(lFile)
  {
    OFConfigFile *iniFile = new OFConfigFile(lFile);
    iniFile->select_section("default");
    if(iniFile->section_valid(1))
    {
      DCMWLM_INFO("-->" << iniFile->get_entry("HttpPort") << "<--");
    }
    else
    {
      DCMWLM_INFO("-->Section not valid<--");
    }
    delete iniFile;
  }

But allways I'm getting "Section not valid", what I'm doing wrong?[/code]

[Jörg Riesmeier]

The class supports more than one hierarchical level (i.e. subsections and so on), see parameter "maxLevel" of the constructor.

[martinrame]

Yes, I know that. Also OFConfigFile_MaxLevel, by default is 2, so it should read my file without problems.

Please, tell me if my understanding of this class is right or not.

1) iniFile->select_section("default");

Here I'm choosing to read all keys inside [default] section.

2) if(iniFile->section_valid(1))

Here I'm checking if the section number 1 is valid. This allways returns False in my example. I also tried with (0) and (2), but i'm getting the same result.

3) iniFile->get_entry("HttpPort")

Here, if the cursor were at section [default], I should be able to get the value of HttPort variable.

This reasoning is ok?

[Jörg Riesmeier]

As far as I can see, you have to specify a maxLevel of "1".

[martinrame]

Well, I changed my code to this:

Code: Select all

  FILE *lFile = fopen("ModalityWorklistServer.ini", "rb");
  if(lFile)
  {
    DCMWLM_INFO("-->1<--");
    OFConfigFile iniFile(lFile, 1);
    iniFile.set_section(1, "default");
    if(! iniFile.section_valid(1) )
    {
      DCMWLM_INFO("-->Section not valid<--");
    }
    else
    {
      DCMWLM_INFO("-->" << iniFile.get_entry("HttpPort") << "<--");
    }
    DCMWLM_INFO("-->3<--");
    fclose(lFile);
  }

...but I'm getting the same results.

[Jörg Riesmeier]

Have you already tried to use upper case characters for the section names and keywords, i.e. "DEFAULT" and "HTTPPORT"?

[martinrame]

Thanks Jörg, making everything upper case it worked.

Now I'll have to figure out how to use the file in normal mixed Upper/Lower case and read it into a string, then UpperCase it, and use OFConfigFile with that string.

[Jörg Riesmeier]

As far as I know, and I'm not the developer of OFConfigFile, you have to use upper case characters only in the program, i.e. not necessarily in the config file.

[martinrame]

Yes!, you are right. Problem solved, then!.
