RE: [libreoffice-dev] -calling a service function from BASIC macro
I was able to fix the macro to use the same service with startThr and stopThr buttons. Thanks for your help Stephan and Michael.

RE: [libreoffice-dev] -calling a service function from BASIC macro
Actually, never mind! I think I have a work around even without Reference. I made my CalcAddinThr a pointer, so it is independent of lifetime of CalcAddimThr_impl . Seems to work through button as well. I think you might have been refereeing to the object created in Basic macro that goes out of scope. Thanks again for taking time to help out on this.

No. But tried to change fundamentalrc SERVICE/TYPES rows to add
$ORIGIN/CalcAddinThr.rdb. scalc complained about duplicate entry.
I assumed that installing the extension informs scalc about my rdb. Maybe not?
I know about CORBA at conceptual level and how UNO works almost like
CORBA just better.
I don't understand how the unopkg and .rdb achieve that theory.
Specifically, where types.rdb fits.
I thought maybe unopkg add is similar to adding in types.rdb ?
Helping you would probably be easiest if you gave the full source code of your
extension,
along with short instructions how to build it (e.g., call make from
within a configured LO SDK environment).
attaching the code, makefile, and readme with instructions. to extract :
tar -zxvf CalcAddinThr.tgz
Attached CalcAddinThr.patch solves the problem. You inadvertently
registered the libCalcAddinThr.so UNO component both the old, active way
(by calling regcomp, which calls your component_writeInfo) and the new,
passive way (by providing a *.component file). You may want to also
remove the obsolete component_writeInfo implementation from your
CalcAddinThr_impl.cxx. (In order to test your code, I also needed an
explicit include of unistd.h for read(2), and drop some apparently dead
copy/paste stuff that caused additional compilation errors; I simply
included those changes in the attached patch.)

RE: [libreoffice-dev] -calling a service function from BASIC macro
Hi Stephan, The function is getting called now, however, I get a crash a bit later when sheet_ is being accessed. I also added a button and attached the macro to it for conveninece of calling. There seems to be some difference between the direct call and call via button/macro. You need to issue make run to test the crash. It invokes the uno exe with calc.uno.so The code is triggered when calc.uno.so connects and tries to access the sheet. I added print statements in the function insertIntoCellS to highlight the crash. It prints creating the header but never gets inside the function insertIntoCellS It doesn't happen if I call the function directly by typing =startthr() in the sheet and start calc.uno.so. I have gotten rid of _writeinfo. The new .ods file with button and new code is attached. Thanks for investing time into this.

[libreoffice-dev] -calling a service function from BASIC macro
Hi, I am having trouble trying to wrap UNO function call in BASIC macro. I got the macro from the following SimpleCalcAddin example. http://wiki.openoffice.org/wiki/SimpleCalcAddIn#Building_.26_Testing 1. mgr = getProcessServiceManager() 2. o = mgr.createInstance(org.openoffice.sheet.addin.CalcAddinSock) 3. o.startThr() (where my idl service returned by getServiceName() is org.openoffice.sheet.addin.CalcAddinSock and it defines a function startThr) I can call the funciton startThr() using = in the spread sheet. Also, the original example RNG is callable from macro by following the example. One difference from the example is that I am using extension. Please advise how to call UNO functions from BASIC macro. I intend to call it on a button click. It seems like invoking macro on button click is simple (Form control to add button and assign macro using the event tab).
