  • [CS3][JS] How to get the file type of current document

    Hi,
    How to get the file type of current opening document (e.g., tif, jpeg, png) using JavaScript with Photoshop CS3.
    I am using file object the open the files one by one in the folder (the files sometimes don't have the extensions).
    If the current document is in tiff format then I need to convert to 8-bit, if its an Jpg image then needs to ignore the file.
    Regards,
    Karthik

    Do you really need to know the file type? What about just checking the bit depth?
    var doc = activeDocument;
    if (doc.bitsPerChannel != BitsPerChannelType.EIGHT) {//Not 8 bit
    doc.bitsPerChannel = BitsPerChannelType.EIGHT;
    //do your save etc
    }else{
        //Ignore

  • How to get the Database type from weblogic Db connection

    I want to use database version control in my application . that means different database type use different Sql Statement. Such as in weblogic7.0 if I create SqlServer JDBC pool then I will use some special Sqlserver sql Statement . such as some join statement. If I create Oralce JDBC pool then I have to use different Sql statement . because these two database support different Sql statement.
    What my question is how to get the database type from the connection.

    For a normal jdbc driver you can use
    Connection.getMetaData()
    To get the meta data, in particular the getDatabase...() methods.
    That might or might not work.
    However, at the very least in the server you have access to the weblogic properties so you can parse the pool property to figure it out.

  • How to get the mime type of the workflow attachment attached to workitem id

    Hi Experts,
    I can attach different types of attachment to the workitem id, lets suppost the attachment type attached is pdf, for this attachment I have an requirement to send the mime type as well. In this case the mime type is 'application/pdf' for pdf files.(for text file it is 'text/plain' and for zip file it is 'application/zip' and so on)
    Do I have any place in ABAP world where I can get the mime type for different types of attachments.
    I dont want to hard code the mime types, and I have checked the transaction 'SMW0', but not sure if this is the correct place to get the mime type.
    Do you see any other way or tables which stores all these mime types.
    Any help/suggestion would be appreciated.
    Thanks and Regards,
    Neerup.

    If you want to know the table name, turn on tracing (ST05) when accessing the MIME types.

  • How to get the OS type (Windows/Unix) on which Siebel Server is running?

    Is it possible to get the OS type (Windows/Unix) on which Siebel Server is running?
    i.e. Through eScript/Workflow etc can we extract the OS type on which SIebel is running?
    I need to create a folder/directory on the machine where Siebel Server is running. But before creating the folder I want to know the type of OS(whether it is Windows or Unix). Can I get this piece of info by some code or using workflow etc?
    I am using eScript to create the folder using Clib command.

    Hello,
    If you are using Reports 9.0.x, you can import the java class (java.lang.System)
    and use the getProperty method (os.name, os.arch, os.version)
    If you cannot / dont want to use java code, you can create an env var (REPORTS_OS for example), initialize this var with the system info and read it with the builtin TOOL_ENV.GETVAR.

    Hi Fred,
    If you open any activities or opportunities, you can see the description if you select new button and click on the process type. It will be display Activities and below that New: Activity. Instead of always displaying the same description I want to override the description according to the process type. For me the application is not activity but Incident. Hope I am clear with the question.

  • How to get the current type of a generic Field Symbol

    Hi Experts,
    I have a Field Symbol:

    I loop around an internal table with a generic structure and assign their fields to my fieldsymbol:
    LOOP AT it_data ASSIGNING <lf_any>.
    After executing this statement I am able to see the current Absolute Type of the field Symbol in debugger.
    For example this could be TYPE ZX_1 in first loop, TYPE ZX_2 in second loop and so on...

    The Reason is I have to CREATE DATA xxx TYPE "current type of the field symbol".

  • How to get the data type of a variable

    Hi
    I'm new to java and I'd like to put some variables with different data type into the HashMap. But when I'm going to get the value
    of the variable I want to know its data type (int,String,long,float etc.) before I do some processing.
    here's my sample code:
    //start...
    Map m = new HashMap();
    String s1 = "String1";
    String s2 = "String2";
    int i1 = 5;
    int i2 = 10;
    m.put(1,s1);
    m.put(2,i1);
    m.put(3,12);
    m.put(4,s2);
    //end...
    when I'm going to retrieve the variable, I'd like to assign it to another variable with the same data type. but the problem is, before
    I assign it I must know its data type so that I could not have an error.
    thanks in advance

    I don't think you will be able to put primitives (ints, floats, etc) in, without wrapping 'em first (java.lang.Integer, java.lang.Float...).
    You can get the type with
    Object biggles;
    // Get biggles
    if( biggles instanceof String )
       System.out.println( "Biggles is a string, yeah biggles" );or with refection
    Class bigglesClass = biggles.getClass();
    System.out.println( "Biggles is of type: " + bigglesClass.getName() );
