How can I hook all the messages passed to the Toolbar?
For example,I want to hook the message TB_COMMANDTOINDEX and the message WM_LBUTTONDOWN passed to the Toolbar.But when I use the function SetWindowsHookEx(...),I get a problem!I don't know how to set the first parameter of the function.Do I need to make two different hooks? or can solve the problem in one?
Thanks for your help!

Why don't you try to hook windows procedure itself ('WH_CALLWNDPROC' as the first parameter) or 'WH_GETMESSAGE'. And can you specify what error do you get?

Firstly I'm very glad to receive your reply.
I don't get any exception at all however the application doesn't run as my expect.Actually,I have been trying to do what as you tell me.When the first parameter is 'WH_CALLWNDPROC' I can hook the WM_MOUSEACTIVATE correctlly and when 'WH_GETMESSAGE ' I can hook the WM_LBUTTONDOWN and WM_LBUTTONUP.
My question is that can I get the WH_GETMESSAGE,WM_LBUTTONUP and WM_LBUTTONUP or any other message at the same time in which way I only specify 'XXXX' as the first parameter rather than use two different hooks?
You know that I'm a chinese and my English is poor.So please forgive my stupidity.
Thanks for your help!

before going into Hooks, if the window is in your application what about subclassing it.

I want to open CorelDraw Files in my project. How i can open that *.CDR files.Which files are supported to open that files. plz Send me details.
Thank you,
|
|

|

if you don't know the internal format of such files, it's the first thing to search for.
unfortunately, I doubt you'll find any answer on this, because it's a proprietary format...

Have you read about version[^] in MIDL , as suggested in reply to your previous post ?

If you're NOT making a UNICODE build then you need to convert the wide-char string pServerInfo->sv101_name to a char one (for instance using WideCharToMultiByte [^] function).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Itz urgent? 
For instance you need to replace the following line
narodachintoo@yahoo.com wrote: m_listctrl.InsertItem(dwEntry++,(LPCTSTR) pServerInfo->sv101_name);
with:
#ifndef _UNICODE
const int SIZE = 0x100;
char szName[SIZE];
int wlen = wcslen(pServerInfo->sv101_name);
WideCharToMultiByte(CP_ACP, 0, pServerInfo->sv101_name, wlen , szName, SIZE, NULL, NULL);
m_listctrl.InsertItem(dwEntry++,(LPCTSTR) szName);
#else
m_listctrl.InsertItem(dwEntry++,(LPCTSTR) pServerInfo->sv101_name);
#endif
BTW error handling left to the reader.

The error message is in bold contrast with SERVER_INFO_101 definition. Could you post, please full code?

What is your platform (the operative system of your machine)?
Try (just a guess-based attempt, don't balem me if it doesn't work) to change the following lines
narodachintoo@yahoo.com wrote: nt wlen = wcslen(pServerInfo->sv101_name);
WideCharToMultiByte(CP_ACP, 0, pServerInfo->sv101_name, wlen , szName, SIZE, NULL, NULL);
with
int wlen = wcslen((LPWSTR)pServerInfo->sv101_name);
WideCharToMultiByte(CP_ACP, 0, (LPWSTR)(pServerInfo->sv101_name), wlen , szName, SIZE, NULL, NULL);

Import the functions from your executable and use it as if it were a local function. Have a look at LoadLibrary(), GetProcAddress(). You will get started then.

The simplest way to use such DLLs is via load time linking:
Add the corrensponding import library as linker input: select Project->Properties menu item, then Configuration Properties->Linker node and add, for instance, comdlg32.lib to Additional Dependecies line.
Usually you have also to include the library header file in you project (it is not the case of comdlg32.dll: windows.h is enough) and make sure that loader is able to find the DLL at runtime (again nothing to do for comdlg32.dll, since it is already in the loader search path).
