Symbian C++ array

[araragi]

wow, looks like login method to this forum was changed, I can't login to my account

anyway, I write application on android platform and I want re-writing its code to symbian C++...

where I can get information about symbian C++ basic command?

for example: I want to make a command base this concept :

if word > 10

this if word > 10 means if strings bigger than 10.

how I can make like that in symbian c++ ?

If you mean the length, there is such method

if(descriptor.Length()>10)

[araragi]

thx for fast response!

before that I search on this forum about string on symbian and found

TDesC::Length

now if I see your code I became a bit confused

if(descriptor.Length()>10)

if(descriptor.Length()>10)
that code I bold above, what it means? I must write describtor in every code?

TDesC is the base class for the descriptors & Length is a member of that class. The word 'descriptor' is just a variable name for a descriptor(to exemplify here) & of course to access the members of a class you need to use a dot('.') or an arrow('->') or double colon('::') depending upon if you are accessing the member directly or using a pointer.

Well, in Symbian C++ there are many types for storing strings. TDesC is a parent type of them. And "Des" actually abbreviates "descriptor", this is how Symbian C++ refers to bounded character and byte arrays.
However for your actual question: in Java, java.lang.String is the string type, and length() is the method for getting the length of a string. Would you really write

if(java.lang.String.length()>10)

? Or would you rather have a variable of type String, and invoke length() on that variable? Now in my example code, "descriptor" is the name of such variable.
Of course you can imagine CharSequence in place of String, that also has a length() method.

More generally, you might want to check out the book on wiki - Fundamentals of Symbian C++/Descriptors and other topics on "Essential Idioms"

thankx alot! I more closer to finishing my apps!

now I need these files to tracking error (I work on visual studio 2003):

S60_S80_SDK_Help_for_Carbide_vs_20.msi.
o S60_30_SDK_Help_for_Carbide_vs_20.msi

where I can download this files?

[vineet.jain]

Any specific reasons of using Carbide.vs as its no longer supported by Nokia. Why not work on Carbide.C++V2.0 & above?

With regards to the files , i do not think they are anymore hosted on Nokia developer website.
