Hi, everyone
It's really urgent for me to learn more about how to create a vertical or docable toolbar with wtl. I'll apprieciate you so much if you give me any advice, even if give me any WTL forum URL, where I may found answers or solutions to my question.
Thanks a lot in advance.

HWND hWndToolBar = CreateSimpleToolBarCtrl(m_hWnd, IDR_MAINFRAME, FALSE, ATL_SIMPLE_TOOLBAR_PANE_STYLE| CCS_VERT | TBSTYLE_WRAPABLE );
That should get you a vertical toolbar. Or try viksoe.dk ( look for atldock or WTL Docked UI )or even here[^] on CodeProject.

Hi,
Charles, Thanks a lot for your reply. I tried according to your hint. But didn't get vertical toolbar. And I don't know what's wrong happened.
Can you contribute a sample WTL project which demonstrates the vertical tooblar implementaion.
You may also send it to me by Email to JackLin5168@gmail.com or JackLin5168@yahoo.com .
Thank you so much. Charles.

Can anyone help me to resole this problem? I think there must be solution to my question.

Did you ever solve this problem? I am interested in the solution as well

Hello,
I have the following code that searches a list of wchar_t * strings.
What I want is a function like this:
vector <wchar_t *="">paths;
find (paths.begin(), paths.end(), L"some string");
What do I need to do to get this to return the string I'm searching for?

This will not return a string but an iterator to the matching string. Your code would look something like this.
bool Comparer : public std::binary_function<wchar_t*, wchar_t*,bool>
{
public:
bool operator()(const wchar_t* s1, const wchar_t* s2) const
{
return (wcscmp(s1, s2) == 0);
}
};
std::vector<wchar_t*> paths;
std::vector<wchar_t*>::const_iterator it;
it = std::find_if(paths.begin(), paths.end(), std::bind2nd(Comparer(), L"some string"));
if (it != paths.end())
{
...

Hi,
I am having an issue compiling the ATL/Com dll;
I have Three classes and their interfaces in a com dll as:
1- IMailInterface
2- IMyInterface1
3- IMyInterface2
Now,MFC application uses these interfaces. My application will never directly deal with 2nd and 3rd interface. Everything will be done with the help of IMainInterface. I want to add a method to IMainInterace as
GetMyInterface1(IMyInterface1** ptr); which will retrun the IMyInterface1 pointer
But while comiling getting an error error as:
D:\Work_ganesh\MPlusSrvOpticalDevice\Work In Progress\Ganesh\Samples\DemoCOM\DemoCOM.idl(18):error MIDL2025 : syntax error : expecting a type specification near "IMyInterface1"
D:\Work_ganesh\MPlusSrvOpticalDevice\Work In Progress\Ganesh\Samples\DemoCOM\DemoCOM.idl(18) : error MIDL2026 : cannot recover from earlier syntax errors; aborting compilation
Error executing midl.exe.
I tried adding header file but it didn’t worked.
Thanks.

Could you post the actual idl code? That would tell me much more about what went wrong.

hi All,
My VB Client using ATL COM works fine while running under Debug mode but in the release mode it gets crashed as ATL COM tries to fire event to the VB Client
Here are the Details of what i have developed as ATL COM in C+
I have developed a simple ATL COM in C++ , This ATL Com has a dependency which is a DLL , this DLL sends a notification to the ATL COM by using a registering a function of a ATL as callback , i have used a static function of ATL Object as callback function as we cannot give member function of the class as callback function due to "this" pointer.
Now Dll sends notification to this static function of ATL COM and this ATL COM send the notification further to the COM Client by firing event.
Important to note , since notification is received by static function of ATL class , so i had to use global pointer to the ATL COM in that static function to Fire_Event , as soon as global pointer fires events VB client in release mode gets crashed
Here is the code snippet
CTest_ATL *g_pTestATL; // Glboal Pointer
STDMETHODIMP CTest_ATL::funSubscribe(void)
{
g_pTestATL = this;
m_hDLL = LoadLibrary(TEXT("\\DLL_PlaceCall.dll"));
if(NULL == m_hDLL)
{
return S_FALSE;
}
return S_OK;
}
// This is a callback "static" function which gets registered to the DLL
// As this static callback function gets called i am firing event using
// global pointer to ATL_COM as shown below
int CTest_ATL::EventCallBack()
{
g_CallMonitor->Fire_IncomingCall(CComBSTR("This is a COM Message"));
return S_OK;
}
Any pointers in this issue will be a great help.....
with regards

Do you have any code you depend on inside an ATLASSERT statement? These are removed in release builds. Another possibility is that the optomizer is breaking something. You may want to create a release build with debug information so that you can step through the code the compiler is actually generating for the release build.
Also, unrelated to your problem, it looks to me like g_pTestATL and g_CallMonitor could be static member variables of CTest_ATL.

Hi Nathan
< Also, unrelated to your problem, it looks to me like g_pTestATL and g_CallMonitor could be static member variables of CTest_ATL >
I made a mistake while giving the question i.e "g_CallMonitor" is nothing it is the global pointer "g_pTestATL" which is firing the event from the static function.... replace g_CallMonitor with g_pTestATL
I have found the solution to the problem but was not really able to understand the whole solution , Below is the link
http://vcfaq.mvps.org/com/1.htm
May be you can through some light....

That makes perfect sense.

I'm not sure what you don't understand. I assume that you've implemented one of the options and had it work, because otherwise you wouldn't know for sure it was a solution. I've used both the hidden window and the GIT solution, so I may be able to answer any more specific questions you might have about them. In general, using multiple threads well will require lots of studying and lots of practice. There are probably articles on CodeProject that can tell you a lot about it.
Nathan

yes Nathan
Your are right that i have implemented one of the options and my work was done...
Since ATL COM is very vast so no idea where to start exactly to find the solution for the same ,also the solution given in the link which i gave requires a lot of deep understanding of ATL before the solution provided can be understood, As you have said there are so many articles in the Code project that can tell me a lot better about ATL and basically the solution given in the links...
so will request to point some of those if you can... ?

Hi,
I’m currently having a problem with getting a WTL project to work. I’m reasonably experienced in C++ native Win32 programming, but I’m very much a novice when it comes to any kind of ActiveX programming.
The situation is this: I trying to write program in Visual Studio 2005 Express using C++ and WTL that is going to interact with another program, eSignal, using an ActiveX API that eSignal provides. I have managed to setup the basics so that I can communicate from my software to eSignal. The problem is that I’m unable to setup an event listener using WTL that manages the events coming from eSignal.
The eSignal developers have provided sample code on how to do this, but it uses MFC. VS2005 Express, which I’m using, has no MFC, so I have to convert their code into WTL, and with my limited experience, I’m unable to do that.
I would greatly appreciate if someone more skilled in WTL and MFC than me, can help me in this matter. I only need to know how to set up an event listener that will process the events coming from eSignal. The rest I should be able to manage. I will provide the MFC sample code below. The part that I’m having problems with is the m_pEvents property of the MainDialog class.
Edit:
Code removed.
I've decided to upgrade to a version of VS that has MFC, so I'll be using MFC instead.

We have a template class as below
template <class T>
class EXP_IMP_CTPERF CTPERFPtr
/*] END Class */
{
public:
// constructors
CTPERFPtr();
CTPERFPtr(const CTPERFPtr<T>& in_CTPERFPtr);
CTPERFPtr(CTPERFObject *in_Object);
CTPERFPtr(const CTPERFPointer& in_Ptr);
// destructor
virtual ~CTPERFPtr();
// assignment operators
const CTPERFPtr<T> &operator=(const CTPERFPtr<T>& in_CTPERFPtr);
const CTPERFPtr<T> &operator=(T *in_Object);
const CTPERFPtr<T> &operator=(const CTPERFPointer &in_Pointer);
// == operator
bool operator==(T *in_Object);
bool operator==(const CTPERFPtr<T>& in_CTPERFPtr);
bool operator==(const CTPERFPointer &in_Pointer);
bool operator!=(T *in_Object);
bool operator!=(const CTPERFPtr<T>& in_CTPERFPtr);
bool operator!=(const CTPERFPointer &in_Pointer);
operator CTPERFPointer&();
operator T*() const;
// returns true if the pointer really points to an object of that class
static bool isClassOf(CTPERFPointer& in_Object);
static bool baseObject(T &in_Pointer);
// to get the object T
T *operator->() const;
T *getPtr() const;
};
Now i have two classes say Base and derived.
class Base {};
class Derived: public Base {};
Now a function gets CTPERFPtr<base /> as one of its input parameter.
void Func(CTPERFPtr<base />& base_in)
{
}
The function call is done like
CTPERFPtr<derived> derive;
Func(derive);
Can somebody explain how this works?
|
|
|
|
|
Explain how what works? The instantiation of derive? The call to Func? The declaration of CTPERFPtr<>?
Please specify more precisely what it is that you are wondering.

when create atl project, then set multi-byte character, compile, I got error:
DllInstall:
error C2440: 'initializing' : cannot convert from 'const char [5]' to 'const wchar_t []'
then try to modify:
form
STDAPI DllInstall(BOOL bInstall, LPCWSTR pszCmdLine)
to
STDAPI DllInstall(BOOL bInstall, LPCSTR pszCmdLine)
compile:
error C2733: second C linkage of overloaded function 'DllInstall' not allowed
any ideas? thanks!

Another way to solve your problem would be to use the system function MultibyteToWideChar to convert your message to unicode when you call DllInstall. (If you're in charge of calling it, that is.) The other solution I can think of would be to just use a unicode project, depending on how much you would have to change for it.

You can change the static const wchar_t szUserSwitch[] = _T("user");
with static const wchar_t szUserSwitch[] = L"user";

hello,
My code snippet for conv is as follows:
string temp_file;
temp_file = my_dir;
temp_file += string ("\\file.tmp");
the my_dir is externed from some other file n is char* with a directory path as its value ("C:\\Projects").
i'm gettin an exception n the application closes.
i want to know wat is the mistake i'v been doing.
Thanx in advance

So, instead of giving you a fish, I'll teach you how to catch lots of fish all by yourself. The course is called Debugging 101:
gReaen wrote: string temp_file;
1. Breakpoint there.
2. Observe the involved variables.
3. Is something smelly? That's the thief. Goto 6.
4. Step. Exception thrown? If so, you should have smelled it in 3.
5. Goto 2.
6. End.
It's likely the assignment (will call string::assign et al under the hood, to which you have the sources and should therefore find the error source) that throws because my_dir is in fact NULL, not "C:\\Projects".
