[api-dev] OOoBean in C++
Hi all, I wonder if someone has tried or succeeded in implementing an OOoBean in C++. Any comments or suggestions would be greatly appreciated Thank you Cheers Harald - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[api-dev] StarBasic - what to recommen and what to avoid?
I have a question about what is recommended to do and to avoid when writing macros with StarBasic. I think that one very convenient thing to do, is to create structs (as they are called in C/C++), such as this one mentioned in another thread a while ago: Type PersonType FirstName As String LastName As String End Type Let's say that we created a rather complex struct with hundreds of variables and other structs, like this: Type PersonType FirstName As String LastName As String Status As MyStruct . . . End Type Type MyStruct Test1 As Integer Test2 As Double Blah As MyOtherStruct . . . End Type Type MyOtherStruct . . . End Type . . . (The dots means and so on…) So, now we want to do stuff. We will create a function that needs, say two string variables. The function is only going to be used for this project, so we don't need to make it general. So here are two options that I could think of: 1: Sub Main Dim A As MyStruct Sim B As Integer A.FirstName=Johnny A.LastName=Andersson . . . B=MyFunction(A.FirstName, A.LastName) . . . End Sub Function MyFunction(A As String, B As String) As Integer Dim C As Integer . . . 'A and B are used to calculate C in some way, how is not important, it's just an example. . . . MyFunction=C End Function 2: Sub Main Dim A As MyStruct Sim B As Integer A.FirstName=Johnny A.LastName=Andersson . . . B=MyFunction(A) . . . End Sub Function MyFunction(A As MyStruct) As Integer Dim C As Integer . . . 'A.FirstName and A.LastName are used to calculate C in some way. No other variables of A are used. . . . MyFunction=C End Function One of the advantages with option 2, is that I don't need to include a lot of parameters when I call the function. In this example it was not that big difference, but sometimes I need maybe 5 or 10 parameters. On the other hand, and this is my question: Isn't option 2 more time consuming? I am not sure how this works, but if the whole structure is copied every time the function is called, I guess it will run slower. So how does it work? Are all the variables copied to the function or is that handled by a reference or something like that? Should option 2 be avoided for extremely complex structures? Or should option 1 be avoided? Can you see more (and better) options for this kind of problem? A bonus question: Is there anything like the C++ class in StarBasic? I think VB use classes too… It feels like objects works like classes. They have their own methods to handle their own variables, just like C++ classes, but can I create my own? Johnny Andersson
[api-dev] ImageURL in a UnoControlImageControlModel
Need to show Embeded Images in a UnoControlImageControlModel. Giving a normal URL to the ImageURL property works fine, but Internal URL's (from embedded Images) do not works Is there a workaround ? Can a internal URL been transformed to a normal URL ? Tryed to use the Graphic-object of the Imagecontrol, but no luck, btw wathts te purpouse of the Graphic-propterty ?

Re: [api-dev] StarBasic - what to recommen and what to avoid?
Your structs should pass by reference unless you purposely pass them by value. see http://www.pitonyak.org/oooconf/OOoConf_2004_Macro_Presentation.sxi so, passing these should not be a performance issue. Much will be determined by how many times things are called as to what you should really do. You can create your own services, but I assume that you would want to implement these in C++ or Java, not Basic.

Thanks for any hint i think that internal URLs for graphics start with vnd.sun.star.GraphiObject:, which is probably only useful as trivia... Take a look at section 5.9.1 Convert a linked graphic to an embedded graphic. in my free macro document, there is some application that might provide a hint using the bitmap. -- Andrew Pitonyak My Macro Document: http://www.pitonyak.org/AndrewMacro.odt My Book: http://www.hentzenwerke.com/catalog/oome.htm Info: http://www.pitonyak.org/oo.php See Also: http://documentation.openoffice.org/HOW_TO/index.html - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
