Thx, for you comment, but this artikel was not what im locking for (or did i have some overlooked??)

Hi,
I've created a dll (C++) containing several functions, which are used inside an Excel-VBA-Project via dll-calls.
What I want: when the dll is loaded into memory (i.e. when one of the functions is executed first time), a general function should be executed (purpose: check licence information etc.).
Is there an event, which is triggered when the dll is loaded ?
TIA M.

BOOL WINAPI DllMain(
HINSTANCE hinstDLL,
DWORD fdwReason,
LPVOID lpvReserved
);
fdwReason -> DLL_PROCESS_ATTACH -> The DLL is being loaded into the virtual address space of the current process as a result of the process starting up or as a result of a call to LoadLibrary. DLLs can use this opportunity to initialize any instance data or to use the TlsAlloc function to allocate a thread local storage (TLS) index.

I would like to know how to pass CStatic as normal variable to member function?
When I try to do it, I will get a message
"cannot convert parameter 1 from 'class CStatic' to 'class CStatic'"!
Please help!
|
|
|
|
|
Post the code.
Why do you want to pass a CStatic variable to a member function ?? 
|
|
|
|
|
I have some repeatly process which will use serveral CStatic variable.
How can I make a member function to do it?
Please help!

Either use a pointer or a reference.

I'm going to patent thought. I have yet to see any prior art.

(Off the top of my head guess)
CStatic might not have a copy constructor.
Try declaring the function as
void FuncX (CStatic &MyStatic);
- or -
void FuncX (const CStatic &MyStatic);

You do not send data to the USB port, you send data to the device attached to the USB port.

Logically true
I have an embeded device attached to the USB my
work is to ensure the data reach to the port rest
is the firmware developers work.

Communication on the USB port is made through a device driver. So, you need to get a handle to this driver (with CreateFile) and then use some IO commands (with DeviceIOControl). Normally you should have a driver with your device and the doc that goes with it.

Hi
I've never wrote an MDI app so this will probably sound like a silly question:
I am using Visual Studio 6. I want to write an MDI program where the documents are dialogs that I design - with buttons, lists, edit boxes, combos etc.
I have no clue how to do that. I've been searching for examples but could not find any.
I tried creating an MDI app and then desinged dialog. Using the class wizard I tried to create a class for that dialog, derived from CView. I then changes the call to the RUNTIME_CLASS macro to use my new class, but I am getting compilation error.
thanks!

You can create your view derived from CFormView, where you can place the controls as you do in dialogs.

Hi,

Actually, documents cannot be dialogs. Moreover this statement makes no sense. Documents are to store data that would be viewed by Views. And saying document you understand a class derived from CDocument. In other words, you might want your views contain dialog controls. It is possible though in case you have a CView derived class, you will not be able yo perform WYSIWYG. So,
you may perform dialog templates with the necessary controls on it and create the dialog object as a child control (dialog) for the views.
Or something may be done with CFormView derived classes.

Microsoft has done a great deal of work to help developers but
should have added a simple learning structure to it.
U can search the MSDN for and example project whose folder name
is viewex.
U will get a hint for what u need this is a simple example for
a class dervied from CFormView.
Thank you

I use function "MCIWndSetVolume" to adjust sound volume. And it works well for MP3. But it returns error message "device doesn't support..." for Wave and Midi. Can I adjust volume for Wave and Midi files using MCI ???
thank you for help.

Try using these functions instead, you can control each 'line' of the sound system WAVE, MIDI, etc. separately.

Hey all, I have a little project I am messing around wiht, it just wraps up some winapi functions in c++ classes. I just changed all the std::string's to std::wstring and all my literal string have L"string" now. And UNICODE and _UNICODE are define. Anyway, everything compiles and runs. the only proplem is nothing renders. Buttons do not show and text control do not show, the only thing that shows in the scroolbars for the textarea.
Any ideas, I bet it is something simple i am missing. Hope you guy and girls have something to point me to.
Cheers

Well, one thing that instantly comes to my mind, is that buffer byte sizes, that were previously calculated using std::string::size, must now be calculated using std::wstring::size * sizeof(wchar_t):
const std::string s1("non unicode");
const std::wstring s2("unicode");
const size_t bytesize1 = s1.size() * sizeof(char);
const size_t bytesize2 = s2.size() * sizeof(wchar_t);and, of course, bytesize1 != bytesize2.
This in combination with memcpy, memset, etc. is a common trap when changing to unicode.

If your code always used the underlying string type's value_type, you would be always able to determine per-element size (and thus any buffer size requirements) correctly - there is no requirement that basic_string only contain narrow or wide character types:
typedef std::basic_string< int > IntStr;
int iValue = 1024;
IntStr isInt( &iValue );
const std::wstring s2( L"unicode" );
const std::string s1( "non unicode" );
const size_t stByteSize1 = s1.size() * sizeof( std::string::value_type );
const size_t stByteSize2 = s2.size() * sizeof( std::wstring::value_type );
const size_t stByteSize3 = isInt.size() * sizeof( IntStr::value_type ); Peace!

Thanks Johann and James. I look for size calculation errors tonight, I beleive that may be part of the problem. As for memory functions, I am not using them currently (i'll double check though).
Thanks

I answered nitpickingly correct at first, but decided that it would be easier to read the answer if I used char/wchar_t and size_t, because your
const size_t stByteSize1 = s1.size() * sizeof(std::string::value_type);
const size_t stByteSize2 = s2.size() * sizeof(std::wstring::value_type); is only half correct:
const std::string::size_type stByteSize1 = s1.size() * sizeof(std::string::value_type);
const std::wstring::size_type stByteSize2 = s2.size() * sizeof(std::wstring::value_type); is correct. And now it's easy to see, for the sake of this exercise, that char/wchar_t and size_t makes reading and understanding easier. But still not correct.

Ohhh... dangerous! Using that correctly to get expected results, means that you probably also need to have a char_traits specialization for int to get where you want.
