Intelligent control resizing.

Hello,
I have a application UI developed using MFC, however the contents of the controls i.e. strings that needs to be displyed on the various controls(static texts, buttons, lilst boxes etc.) on the dialog boxes are determined at run time. So I need a Intelligent control resizing and positioning utility so that asthetics of the dialog box is maintained when one or the other control is stretched from its statically designed area.
This utility is also required for other purpose : I wish to internationalize my application and I do not want to maintain seperate resource DLL for each language supported by my application.

Any pointers or clues in this direction will be helpfull.

Thanks
Suyash

Hi Sarath,

Thanks, its of great help, in particular http://www.codeproject.com/useritems/SizingDialog.asp,
Though it doesn't solve my problem completely, i can re-use it.
However I still feel there should be some utility developed particularly for my problem, as its very generic requirement for multilingual application if we do not wish to maintain seperate resource dlls.

Anyways, Thanks much.

Check GetVolumeInformation() API where you get the information of the volume serial number in lpVolumeSerialNumber parameter.

Here you get more information[^]

If you need volume's serial number (for logical disks C:, D:, etc.), you can use GetVolumeInformation function.

If you need serial numbers of your hard disks as physical devices, you can follow the famous Windows Management Instrumentation (WMI) way, which does not look so simple:

#define _WIN32_WINNT 0x0400
#include <objbase.h>
#include <comdef.h>
#include <Wbemidl.h>

# pragma comment(lib, "wbemuuid.lib")

_COM_SMARTPTR_TYPEDEF(IWbemLocator, __uuidof(IWbemLocator));
_COM_SMARTPTR_TYPEDEF(IWbemServices, __uuidof(IWbemServices));
_COM_SMARTPTR_TYPEDEF(IEnumWbemClassObject, __uuidof(IEnumWbemClassObject));
_COM_SMARTPTR_TYPEDEF(IWbemClassObject, __uuidof(IWbemClassObject));


int main()
{

    CoInitializeEx(NULL, COINIT_MULTITHREADED);
    CoInitializeSecurity(
        NULL,
        -1,
        NULL,
        NULL,
        RPC_C_AUTHN_LEVEL_DEFAULT,
        RPC_C_IMP_LEVEL_IMPERSONATE,
        NULL,
        EOAC_NONE,
        NULL);

    IWbemLocatorPtr locator;

    CoCreateInstance(
        CLSID_WbemLocator,             
        0, 
        CLSCTX_INPROC_SERVER, 
        IID_IWbemLocator, 
        (LPVOID *)&locator
        );

    IWbemServicesPtr services;

    locator->ConnectServer(
        _bstr_t(L"ROOT\\CIMV2"),
        NULL,
        NULL,
        0,
        NULL,
        0,
        0,
        &services
        );


    IEnumWbemClassObjectPtr enumerator;
    services->ExecQuery(
        bstr_t("WQL"), 
        bstr_t("SELECT * FROM Win32_DiskDrive"),
        WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, 
        NULL,
        &enumerator);

    IWbemClassObjectPtr object = 000;

    for( ; ; )
    {
        ULONG ret;
        enumerator->Next(WBEM_INFINITE, 1, &object, &ret);

        if( ret == 0) break;

        _variant_t variant;

        object->Get(L"Caption", 0, &variant, 0, 0);

        MessageBox(0, _bstr_t(variant), "The serial number is:", MB_OK);
    }

    return 0;
    //
    // TODO: check any call for errors
    //
}

Hope it helps.

I cannot find this file

Wbemidl.h

Viorel.9-Jun-06 3:15

The "WbemIdl.h" file is located in "Vc*\PlatformSDK\Include\WbemIdl.h" subdirectory of Visual Studio 2003 or 2005. Are you using another compiler? Or may be you have a reduced variant of Visual Studio.

WMI includes more header files, libraries and DLLs. In Windows 98, WMI has to be installed separately.

I think you would have to download WMI from Microsoft site.

And it would not be possible for me to move to Visual Studio .NET 2003 or higher.
