where can i find comctl32.lib ( code::blocks )

Pages: 12
nvrmnd (656)
Is it pre-installed ? or is only available on Visual Studio ?

i am using code::blocks / mingw

And is libcomctl32.a w/c i found under \lib in mingw same as comctl32.lib ? i've tried linking it and it doesn't seem to work

Thank you

On my Win7 32 bit box I have Code::Blocks installed at ...

C:\Program Files\CodeBlocks

And under that is ...

C:\Program Files\CodeBlocks\MinGW\Lib\libComCtl32.a

MinGW prefaces all libs with the lib prefix. So if you interoperate between Microsoft and MinGW you'll need to take those naming conventions into consideration.

But your code should work in a MinGW Codeblocks development environment once you correctly set the link commandline. Do you know how to do that?

You can simply use 'comctl32' without .lib suffix if you use MinGW instead of 'libcomctl32.a'.

It kind of matters what you are trying to do with the COM library because the default version of MingW that comes with Code::Blocks doesn't have full COM support. I've read that some other branches of MingW do and one of them gets a pretty solid review from one of the regular contributors here otherwise Code::Blocks likes MS VS 2010 just fine.

I don't believe shadow_fiend's question had anything to do with COM, as in Microsoft's 'Component Object Model' ComputerGeek. Rather, ComCtl32.lib/ComCtl32.h contains the obj code / function prototypes for Microsoft's 'Common Controls' library, which would be such stuff as the Treeview control, Calendar control, sliders, etc?

It looks like you're right! I don't know why I get that mixed up with the Ole**.lib stuff.

i don't know how, what i did is
build options -> linker settings -> link libraries

then i add libcomctl32.

and it didn't work, am i missing something ?

Did you call InitCommonControlsEx() ?

InitCommonControlsEx


BOOL InitCommonControlsEx
(
    LPINITCOMMONCONTROLSEX lpInitCtrls
);

Registers specific common control classes from the common control dynamic-link library (DLL). 

Returns TRUE if successful, or FALSE otherwise. 
lpInitCtrls  Address of an INITCOMMONCONTROLSEX structure that contains information specifying which control classes will be registered.

There is no such thing like 'libcomctl32', use 'comctl32' only.

As for your compiler error, define WINVER manually to target xp or higher (0x0501) and add a comctl32 v6 manifest to your resource file (this is optional, but otherwise it will look very bad style).
nvrmnd (656)
#define WINVER 0x0501 didn't work, but i've found another solution in the net: #define _WIN32_IE 0x0300

i compiled it and now it says
comctl32.lib no such file or directory


do i have anything else to configure ?

EDIT Ignore this reply, it worked now, i've changed linker settings -> policy

anything wrong ? ( i've also updated my code above in case someone would like to try )

please help, i'm new to this stuff and i cannot track the cause of SIGSEGV

Duthomhas (13119)
I can't find any info about SIGSEGV with your condition. There are quite a few versions of comctrl32.dll though. I wonder if:

- your application is linking to the version(s) you think, and

- if the TBBUTTON structure definition you ar using matches what the DLL thinks it ought to be.

Sorry I can't be of more help.

I'm curious as to why you keep stating that modoran. I've checked several of my various laptops with MinGW installed, and that file, i.e. libcomctl32.a, is in the /lib directory on all of them.

@freddie1:
Because on the G++'s command line, -lcomctl32 will search for libcomctl32.a .
Besides, InitCommonControlsEx is in Commctrl.h as of http://msdn.microsoft.com/en-us/library/windows/desktop/bb775697(v=vs.85).aspx

So, #include <Commctrl.h> at the beginning of your file.

Wait, i'm getting confused
There are quite a few versions of comctrl32.dll though.

Is comctrl32.dll ( w/c i found under system32/ ) is the one i should link to my application ?

and why are there 2 entities of comctrl32, a dynamically linked( found under system32 ) and statically linked one( libcomctrl32.a ) ?

So, #include <Commctrl.h> at the beginning of your file.

why is it capital c ?

@shadow fiend:
Capitalization is not important on Windows.
You can also have #include <cOmMcTrL.h> .
By the way, linking to libcomctrl32.a doesn't automatically mean statically linking.
I don't think there's any way to have a static link to windows' API.
libcomctrl32.a will redirect you to the right DLL, so you don't have to worry about that.
