Hi,
I am usinf the CRegKey class of ATL but when I am compiling it is showing the error
error C2039: 'QueryStringValue' : is not a member of 'CRegKey'
C:\Program Files\Microsoft Visual Studio\VC98\ATL\INCLUDE\atlbase.h(4714) : see declaration of 'CRegKey'
Can anybody tell me whats the problem.
Thanks in advance.

It seems you forgot to include header file.
|
|
|
|

Not the case. Here's the error message again:
C:\Program Files\Microsoft Visual Studio\VC98\ATL\INCLUDE\atlbase.h(4714) : see declaration of 'CRegKey'
It's clear from the error message that the correct header was included.

Hi,
Can you tell me which header file to use.

You're already including the correct header. See here[^].

Do you check that this function really exists in CRegKey? May be you are using incorrect case somewhere or the function is not really there in the CRegKey. Or could also be the case of a missing header file.
Somethings seem HARD to do, until we know how to do them.

Again and again, you're using the MFC version with ships with Visual Studio 6 and pretending it has the same features of later versions. Can you see QueryStringValue method in this documentation page [^]?

There is no such method (at least there isn't in MSVC6, which you seem to be using). Here's the definition (which you could have easily found yourself):
class CRegKey
{
public:
CRegKey();
~CRegKey();
public:
operator HKEY() const;
HKEY m_hKey;
public:
LONG SetValue(DWORD dwValue, LPCTSTR lpszValueName);
LONG QueryValue(DWORD& dwValue, LPCTSTR lpszValueName);
LONG QueryValue(LPTSTR szValue, LPCTSTR lpszValueName, DWORD* pdwCount);
LONG SetValue(LPCTSTR lpszValue, LPCTSTR lpszValueName = NULL);
LONG SetKeyValue(LPCTSTR lpszKeyName, LPCTSTR lpszValue, LPCTSTR lpszValueName = NULL);
static LONG WINAPI SetValue(HKEY hKeyParent, LPCTSTR lpszKeyName,
LPCTSTR lpszValue, LPCTSTR lpszValueName = NULL);
LONG Create(HKEY hKeyParent, LPCTSTR lpszKeyName,
LPTSTR lpszClass = REG_NONE, DWORD dwOptions = REG_OPTION_NON_VOLATILE,
REGSAM samDesired = KEY_ALL_ACCESS,
LPSECURITY_ATTRIBUTES lpSecAttr = NULL,
LPDWORD lpdwDisposition = NULL);
LONG Open(HKEY hKeyParent, LPCTSTR lpszKeyName,
REGSAM samDesired = KEY_ALL_ACCESS);
LONG Close();
HKEY Detach();
void Attach(HKEY hKey);
LONG DeleteSubKey(LPCTSTR lpszSubKey);
LONG RecurseDeleteKey(LPCTSTR lpszKey);
LONG DeleteValue(LPCTSTR lpszValue);
};

How to post a message from MainFrm to the dialog , psl adv

Please, don't repeat your questions. Everybody saw your question the first time, no need to post it twice: this is considered rude behavior.

Hi all,
i have a application(Exe) which will load 2 dlls A.dll and B.dll, A.dll will create a map table(STL Map object) i have to use this map object in B.dll how should i do this ?
Using pragma Data section or using Memory map files ?
Thanks in advance

This is quite a complicated thing and there are may ways to do it and many pitfalls. If your not sure how to do this (and perhaps even if you are) perhaps it's best to use an existing library such as Boost.Interprocess[^].

If both A.dll and B.dll are in same process, you dont need to share it using #pragma . Just declare the variable as global and export it in the A.dll.
Also you please note the below two points
1. Sharing the data segments using #pragma is used to share a data in a dll across multiple process. Not between two dlls in same process or multiple process.
2. You will not be able to share a map using shared section, because the map will be holding pointers to many dynamically allocated memories, which is valid only in corresponding process. Trying to access it from another process result in access vialotion.

I want to pass parameter to dialog,

and also I wnat to post a messsage from MainFrm to the dialog, when the dialog is active.
Pls advice

Pass it before calling DoModal (you can for example pass it in the constructor, or in a separate setter function).

And why do you need to send a message to modal dialog?

Do you know a modal dialog call is a blocking one?

Why don't you make the dialog modeless?
See, for instance, here [^].

What do you mean ? You would like to be able to still interact with your main window when your modal dialog is shown ? That's not possible, unless you use a non-modal dialog.
