Lpwstr

I have a LPWSTR with a value and I want to convert it to char* or string.

Is there a simple function to do this?

LPWSTR is actually wchar_t* (or the equivalent of).

You can use this raw under 2000 (it's a Unicode string), but for 98 you need to convert it. Search the forum for WideCharToMultiByte and you should be sorted :)

Ok, I am in 2000, so how do I do this?

What are you using? Is it a console app?

I think you can just output it to wcout in the usual manner. It's hazy trying to use both in one program, though - either convert everything to Unicode, or everything to the multibyte set (the normal char* stuff...yes I know it's called multibyte but for most characters 1 byte will suffice).

It is in console for now.

To be honest with you, I am in a bit of a mess. I am trying to enumerate the Protected Storage in W2K like here http://www.codeproject.com/w2k/pseenuma.asp

Here is the code I have so far.

Code:

---



#include <windows.h>
#include <iostream>
using namespace std;


// import type library.
#import <pstorec.dll> no_namespace

// function pointer
typedef HRESULT (WINAPI *PStoreCreateInstancePtr)(IPStore **, DWORD, DWORD, DWORD);


void main(){

        CoInitialize(NULL);
       
        HMODULE hPstoreDLL;
       
        hPstoreDLL = LoadLibrary("pstorec.dll");
       
        PStoreCreateInstancePtr PStoreCreateInstance;
       
        PStoreCreateInstance =
                (PStoreCreateInstancePtr)GetProcAddress(hPstoreDLL, "PStoreCreateInstance");

        IPStorePtr spPStore;

        HRESULT hRes;
       
        hRes = PStoreCreateInstance(&spPStore, 0, 0, 0);

        IEnumPStoreTypesPtr spEnumTypes;

        hRes = spPStore->EnumTypes(0, 0, &spEnumTypes);

        GUID typeGUID;

        unsigned long ul1;

        for(int i = 0; i < 5; i++) // Internet Explorer Type
                hRes = spEnumTypes->Next(1, &typeGUID, &ul1);


        IEnumPStoreTypesPtr spEnumSubTypes;

        GUID subtypeGUID;

        hRes = spPStore->EnumSubtypes(0, &typeGUID, 0, &spEnumSubTypes);

        hRes = spEnumSubTypes->Next(0, &subtypeGUID, &ul1); // Internet Explorer Subtype

        IEnumPStoreItemsPtr spEnumItems;

        hRes = spPStore->EnumItems(0, &typeGUID, &subtypeGUID, 0, &spEnumItems);

        LPWSTR lpwstr;
       
                hRes = spEnumItems->Next(0, &lpwstr, &ul1);
                wcout << lpwstr << endl;


        CoUninitialize();
}

... and you see what happens. :eek:

PS - Anybody that knows win2K Protected Storage, feel free to jump in.

Code:

---

hRes = spEnumItems->Next(0, &lpwstr, &ul1);

---

Shouldn't that just be "lpwstr" not "&lpwstr"?

Well, one would think it should be. The parameter is actually

LPWSTR* rgelt

go figure.
