I am working with the Explorer kind of MFC Application.
Here I face a problem of when I call a Context Menu from TreeView and when I Handle this menu event from Mouse Click.
- Context Menu is working fine.
- I want to handle the menu control from MOUSE RIGHT CLICK MESSAGE.
- Control ID is also captured correctly when Mouse is clicked (As per expected).
- But When program calls a dialog from this point. The dialog has not a focus on it Even I try so hard Focus on dialog controls are not coming.
- If I swith from this application and coming back to this application again it is working fine. (Change of Focus from one application to another).
How can I resolve this problem?

Can you post the code calling the dialog ?

I had this function in a class i defined :
void AddJob(IRunnable &NewJob);
Now there is a Windows API that is also called AddJob, but with completely different parameters and return type. The class was defined inside a static library. When i wanted to call that function in an application that linked my library :
TestInstance.AddJob(IRunnableImplInstance);
i got a linker error "Unresolved external". I renamed my functio now, and all works well. But i wonder why the error occured in the first place. The function had completely different parameters, return types and class context (the API is in the global namespace). I use VC++ 6. Does anyone have an explanation for that ?

I believe that C functions, even when compiled by a C++ compiler only differ by name and not by return type, name and parameter list for C++ member functions. Would this be the culprit?

I don't know for shure. But i think unsell you declare a function __stdcall explicitly, it will always be translated into that long C++ symbol lingo. However, why would that result in an unresolved external linker error ? If anything it's a redefinition of a symbol, but not no definition of that symbol.

You're correct. I've got it backwards. My explanation would result from a redefinition error. Not what you are after. Sorry about that.

This one is going to make you laugh  and cry  ...
In the Microsoft headers, there are TWO definitions for almost every function - the ANSI version and the UNICODE version. The AddJob in the Microsoft headers is redefined as either AddJobA or AddJobW. The precompiler will see any similar text and change the name.
Now, in your static library, you must NOT have included anything close to the printer header, so the AddJob stayed as 'AddJob', but in your project, when you went to use it, and maybe you directly or indirectly included the files which redefined AddJob, so it did not find AddJobA or AddJobW in your library at link time - your project's main OBJ module was looking for the wrong name.
I had been tripped up by this one time a while back as well. You have to be careful naming anything requiring linkage the same as any one of the bazillion WIN32 functions out there!
This would also explain why once you changed the name your 'problem' went away.
Any sufficiently gross incompetence is nearly indistinguishable from malice.

Well, it made me laugh more than cry. I knew that most of the functions are mapped to the A and W version via macros, but i didn't make the connection. Well, you just gotta take it with humor ...

From an dialog based win32 app I awant to load a menu in the dialog. How to do that?

See LoadMenu On MSDN it has examples that I think its helpful for you

Hi, How do I make dynamic array of String class in VC++? Thanks in advance. Priyank
|
|
|
|
|
use std::vector<std::string>
don't forget to #include <VECTOR> and <STRING>
|
|
|
|
|
Depending on what you want to do with the String, and weather it doesn't matter if they get copied or not you should use std::vector<std::string::reference> i guess.

Which is exactly what toxcct suggested.

Actually I want to make two dynamic arrays of String and then need to do some comparison with each other. I made vector of String class and tried to push_back methode to add string to it but it gives me error like “cannot convert from 'System::String __gc *__gc * ' to 'System::String __gc ** ' Cannot convert a managed type to an unmanaged type”
My code is
vector<String*> strArr;<br />
strArr.push_back("string1");<br />
strArr.push_back("string2");
can I know what is the problem with my code?
Thanks

How about:
vector<String*> strArr;
strArr.push_back(new String("string1"));
strArr.push_back(new String("string2"));

I tried it. It gives same error  I am writing full error message here.
error C2440: '=' : cannot convert from 'System::String __gc *__gc * ' to 'System::String __gc ** '
Cannot convert a managed type to an unmanaged type
C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\vector(579) : while compiling class-template member function 'void std::vector<_Ty>::push_back(System::String __gc *const __gc & )'

[
_Ty=System::String __gc *
]
eAssessment.cpp(20) : see reference to class template instantiation 'std::vector<_Ty>' being compiled

And this is under push_back methode.

This is a Managed C++ issue, of which I am very unfamilar. Try here.

If this is managed code (you didn't mean to use CString instead of String) then you should
probably use one of the classes in System.Collections namespace instead of a vector.
Check out ArrayList and Queue classes.
