Hi!

I guess you are right! you mean I have to derive my own CArray class? isn't another way I mean another array class that can do the trick!
thanks

No, I mean you have to provide a =operator and a copy constructor for your structure. Inside those, instead of simply assigning the arrays, like this:

mystruct::myStruct(const mystruct& copy)
{
  array1 = copy.array1;
}

you will need to copy the content of the array by iterating over it.

Electronic75 wrote:

std::string or std::list maybe ? But you have to be carefull of what is inside those arrays. If you store pointers, you will have a copy of the original pointer pointing at the same memory location, so you should only delete one of them (so, it's a bit dangerous).

How to send data between PC usb port to a WinCE usb port?

Hi All,

I need to write a program in VC++/MFC that can send data between PC usb port to a WinCE usb port?

Where to start??

Any help???

However i have gone through the following links:

What do you need to do ? In fact you are looking at it the wrong way: don't take into account that you have a USB port in between, this will be 'hidden' for you. In fact you need to communicate with the driver of the PocketPC (generally through ActiveSync). What are you trying to achieve exaclty ? Take a look at RAPI[^], this is what is already available.

Hello everyone,

I am developing a C++ COM client (COM consumer) using #import statement, even if it works fine, I still find one issue when reading MSDN document about #import.

http://msdn.microsoft.com/en-us/library/8etzzkb6(VS.80).aspx

In the document, it mentioned two header files will be generated -- TLI and TLH files. But in my client project directory, there is only one tlh file. I am using VS 2008. My questions is why the tli file is missing, if not missing, where is it?

thanks in advance,
George

probably you are importing tlb with no_implementation attribute.

i do not have much experience with COM, but how does your TLH file look like
because TLI file contains implementation for compiler generated wrapper functions specified in .tlh file.

I cant see any function in TLH so i think compiler is not generating corresponding TLI.

I tried creating test.tlb without any contents and it gave me only .TLH

// Created by Microsoft (R) C/C++ Compiler Version 12.00.8168.0 (1060d860).
//
// e:\users\sandip\trialmfc\debug\test.tlh
//
// C++ source equivalent of Win32 type library test.tlb
// compiler-generated file created 09/11/08 at 13:29:04 - DO NOT EDIT!

#pragma once
#pragma pack(push, 8)

#include <comdef.h>

namespace TESTLib {

} // namespace TESTLib

#pragma pack(pop)
</comdef.h>

Does it make sense.

Thanks Sandip,

I have tried, you are correct. When adding some methods in some interface, the tli file is generated.

Here is the content of tli file when I add method FooAbc to interface IAbc.

inline HRESULT IAbc::FooAbc ( ) {
    HRESULT _hr = raw_FooAbc();
    if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
    return _hr;
}

how to retrieve all details on installed products in system

hi everyone, m working on retrieving all MS products that are installed on a system and that appear in add/remove programs. i heard about WMI, with which we can retrieve. But, its disadvantage is, it retrieves only those softwares that are installed by MSI. i also found another way that is registry where HKLM/software/microsoft/windows/currentversion/uninstall path where we can get all installed products. but, here m not getting any details about child products that come along with parent product. is there any way that you can suggest?

Well you said registry is best place for you I think on the registry you can see a folder its name is install I think.

The BRTAPI.c file is added to project? or else linker couldn't find the corresponding obj file while linking and hence the error.
