The call to RegisterAll() was present but before the server started other servers, inshort before it completely initialized its state. So I moved the RegisterAll() call after the initialization just before its main window is shown. The call to RegisterAll() informs the OLE System Dll's that the coclasses inside this server are ready to handle calls.

hi i had found a project but this line give me confusion,if any body can help me i will be thankful to him.
std::vector<handle> vThreads;
HANDLE hThread = CreateThread(NULL,0,CMyService::Serve,(void*) pServe,CREATE_SUSPENDED,&dwServe);
vThreads.push_back(hThread);//i m talking about this line,
will that thread will be executed in backgroundor not,what will happen to that thread.

The CREATE_SUSPENDED flag means the thread will not run until you call ResumeThread() on its handle.

This line stores the handle returned by the CreateThread API.Which is helpful for controlling the thread.
And thread is created in suspended mode.

i create an ATL project and insert an full control named IMyClient .the class is
CMyClient.Then i add other C++ class CDealEvent .Now i want to use the function 'onidle'
that in CMyClient ,how should i do? the code like this:
///////////////////////////////////
//MyClient.h
///////////////////////////////////
#include DealEvent.h;
class ATL_NO_VTABLE CMyClient:
public ......
{
...........
///////////////////////////////
//here i add a function onIdle
///////////////////////////////
public:
HRESULT onIdle(void);
CDealEvent* pEvent;
HRESULT FinalConstruct()
{
pEvent=new CDealEvent();
}
}
///////////////////////////////////
//MyClient.cpp
///////////////////////////////////
HRESULT CMyClient::onIdle(void)
{
//some code here
}
CMyClient::CMyClient():pEvent(NULL)
{
}
//////////////////////////////////
//add other c++ class DealEvent.h
/////////////////////////////////
class CDealEvent
{
public:
callonIdle();
}
//////////////////////////////////
//add other c++ class DealEvent.cpp
/////////////////////////////////
void CDealEvent::callonIdle()
{
//here i want to call ' onIdle ' that in CMyClient

You can use CComObject::CreateInstance, but I doubt, you need same instance, is it?

Hi,
I'm porting one of the dll from vc6 to vc8. In doing so I have created a complete framework to create a dll and subseqently add atl objects.
By default the framewaork adds the follwoing code in the main app file
class MyClassModule : public CAtlDllModuleT< MyClassModule>
{
public :
DECLARE_LIBID(LIBID_MyClassLib)
DECLARE_REGISTRY_APPID_RESOURCEID(IDR_MYCLASS, "{7C00C752-3DA7-4CB9-B721-7F39F9FEDD2E}")
};
In previous versions of ATL CComModule _Module was used which has been replaced by CAtlBaseModule.
Problem:
In the current application there is an
extern CComModule _Module in stdafx.h
and definition in main app file as CComModule _Module .
The global object _Module is being used in other files which include the stdafx.h file.
These files call methods like _Module.GetModuleInstance () and _Module.GetResourceInstance ());
Questions)
1)Is a global object of this class MyClassModule to be created and will the same exact functions as used on _Module be used here too.
2)Also since the above derivation is in in my app file how will the class MyClassModule and the global object of it be visible to other projects in order to call upon the functions.

Hi everybody,
can anybody please direct me to a web site or an article (I could not find anything helpful) about how to make controls to be transparent. I use Visual Studio 2005 to make a Visual C++ dialog based application, and I use ATL only. Even though I specify a static control should be transparent, it is not. The background is static, it does not change, but neither static controls nor the captions of group box controls are rendered transparently.
Thanks for your help.
|
|
|
|
|
Okay, I found it:
I need to handle the message OnCtlColorStatic:
::SetBkMode((HDC)wParam, TRANSPARENT);
return (LRESULT) GetStockObject (HOLLOW_BRUSH);
and my static controls are all transparent.
But I can still not make group box captions to be trtansparent.
Thanks.

I have a class that I wrote I C# and I want to use it in a VC++ project without turning the C# class into a COM object. These are the steps that I've been given by a colleague:
I don't have code sample but I have steps how to do it. But my problem is how do I do step 9? Does anyone have a code sample of how to access the C# methods in VC++ through a type library??
Much appreciated!
L
1. Create a C# class
2. Generate a key for it - sn -k keyfile.snk
3. Put an assembly directive at top of file
[(Assembly: AssemblyKeyFile("keyfile.snk")]
4. Compile
5. regasm file.dll /tlb to generate the COM Type Library
6. gacutil -i file.dll to place file in GAC
7. Copy the generated typelibraries into the directory of your ATL/C++ project
8. #import file.tlb no_namespaces named_guids (look up the reff for exact syntax)
9. Compile ATL/C++ code and you will have access to the interfaces through the types in the imported tlb

The steps you posted turn the C# class into a COM object

So first you say you don't want to use COM then you ask:

So the two questions contradict each other, therefore, what is your question?

Where do you get the error? Also, tick the "Ignore HTML tags in this message (good for code snippets)" so we can read the code proberly; it's hard to read code without indentation.

Hi,

By default the framewaork adds the follwoing code in the main app file
class MyClassModule : public CAtlDllModuleT< MyClassModule>

};
In previos versions of ATL CComModule _Module was used which has been replaced by CAtlBaseModule.
Problem:
There was an extern declaration as extern CComModule _Module in stdafx.h and definition in main app file as CComModule _Module .
How do I replicate the above behaviour in the new version. as CComModule is known to stdafx.h all other classes could use _Module. How do I use the global instance of MyClassModule in other modules.
|
|
|
|
|
CComModule was declared in ATLBase.h. So there was not any problem previously.
You may need to move MyClassModule class definition to separate header file.
And declare its object as extern in stdafx.h. Before that you need to include class header.
Or in other words adopt method in c++ to make visbile any global object across applicatin.
|
|
|
|
|
Where do I define my global object and I suppose the global object is to be created out of the class MyClassModule. Is it the application.cpp file?
Also how do I call methods like _Module.GetModuleInstance (), _Module.GetResourceInstance ()) on the new global object.

Hi All,
I have some queries regarding font.
Q1. What is exactly a 'Bitmap Type Font', 'TrueType Font'?
Q2. Difference between the two.
Q3. Difference between 16-bit version and 32- version of a Font?
q4. How can we identity whether a font is 16-bit version or 32-bit?
Anwsers to any of the above will be great help for me.
Thanks in advance

I have something like this:
class SomeClass
{
...
template <typename _Iter>
void SomeFunction(_Iter begin, _Iter end)
{
...
}
}
and I want to specialize de template when I use vector::Iterator. I try this:
class SomeClass
{
...
template <typename _Iter>
void SomeFunction(_Iter begin, _Iter end)
{
...
}
template<class T>
void SomeFunction(typename std::vector<T>::iterator begin, typename std::vector<t>::iterator end)
{
...
}
}
The source (under Visual 2005) complies without errors nor warnings. When I try to use that specialization (something like this):
...
vector<midata> data;
myclass.SomeFunction(data.begin(), data.end());
the program calls the first one instead of the second (as I expected).
Is it possible to program that specialization? How?
Thank you in advance

Hello Juan,
The overload you're proposing (it's an overload, not a specialization) is illegal because std::vector<T>::iterator is not what the standard calls a proper deduced context. An example will help clarify why the language cannot accept contexts of the form a<T>::b where T is a template parameter. Consider the following:
template<typename T>
struct foo
{
typedef void * type;
type a;
};
template<typename T>
void f(typename foo<T>::type a){...}
int main()
{
foo<int> x;
f(x.a);
}Do you see why this cannot work? Although it seems like the call f(x.a) should deduce T to be int, in reality it is impossible to make this deduction, as foo<T>::type is void * for every T.
In your particular case, you might want to replace this overload (which can't work for the reasons explained) with some machinery to dispatch SomeFunction based on the category of the iterator (bidirectional, random-access, etc.) If you need help with this feel free to ask.
Hope this helps,
