for example, if all the necessary interfaces for a windowless control is implemented as below, how to create the control on a dialog, and let it working properly?

class my_ctl : public IOleInPlaceObjectWindowless, public IOleInPlaceSiteWindowless, public IViewObjectEx
{
...
}

Thanks in advance. BTW, I want it be as simple as possible, just let it work.

Thanks, agree with you.

If using a memory pool, it should be faster, doesn't it?

the test result on my computer:

//case 1
2153 // not using pool
16 // using pool
//case 2
15 // not using pool
32 // using pool
// case 3
2668 // not using pool
14976 // using pool
Press any key to continue . . .

tried, but still not work if popup the context menu, it plays

In CMyApp::InitInstance

// not work
SwfWnd * w = new SwfWnd;
SwfWnd->Create(...);
MSG msg;
While(GetMessage(&msg, SwfWnd->GetHWnd, 0, 0))
{
TranlateMessage(&msg);
Dispatch(&msg);
}
// work
SwfWnd * w = new SwfWnd;
SwfWnd->Create(...);

COtherDlg dlg;
dlg.DoModal();

Any way to make the 1st version work?

about its programming environment :|

Index is removed from msdn by default in visual studio 2010. Although there are some plugin, but not as good as in VS2008. BTW, when opening and running two or more instances of VS2008, the UI will be out of order. For example, running a server and a client in two instances of VS2008, when one aborted, one of the UI became out of order, I don't remember which. What's like, the index in mysql document is also removed. ============ If search works, it is also possible to build an index only once instead? I think M$ is collecting in the search procedure for analysis, for its bing.com.

With out index, it become not that efficient when finding help. The TOC (or bookmarks in pdf) is not so efficient. What worse is html, I have to return to TOC to relocate. BTW, index is removed by default in visual studio 2010. Why index is gone?

A class is ok in the case. But in another case, the life scope of the object of the class may larger than the try..catch... block, this can bring problems, just because the scopes are not inconsistent. However, there seems no proper way which is also efficient. BTW, is there any language that can provide some thing like constructor and distructor for a function?

You can try: 1. use memory dc 2. draw what is necessary

But when I manapulate a dababase instead of memory, for example, a prepared statement, I need to close it before leave. Hope it can be common.

Yes, it is fine. But when I manapulate a dababase instead of memory, for example, a prepared statement, I need to close it before leave. Hope it can be common.

I think exception is rarely happened, I want to catch it in the more outside fucntion, like main.

How to let the code be more elegant? Just too much delete. BTW, while not to deal the exception in side the function, try catch finally can't be used.

void f()
{
char * buf = new char[128];
...
if (...)
{
delete []buf;
throw runtime_error("...");
}
...
if (...)
{
delete []buf;
throw runtime_error("...");
}
}

===================== I think what I need is something like constructor and destructor, but for a function. By overriding operator() of a class may solve some problem, but the function it hard to be re-entrantable, and other misc problems. Most of the cases the function should be short, so this couldn't be a problem, but in some rare case, it has to deal a lot of data, and the function looks very long.

like mathematica ;P

1. new project 2. Visual C++/Win32/Win32 Console Application 3. Enter the name of the project (TestNamespace), click ok Then it pops up a windows, show some code in html, with jscript. I tried to copy it here, but it isn't support to be copied. BTW, I have tried to repair it using the dvd, but it didn't solve the problem.

when I finished the wizard, a popup window showed the following text:

    Win32 Application Wizard

...

BTW, not only in vs2010, another application (mobicreator) showed the familiar text. How to fix it? Thanks.

like Windows' GetMessage

Is it like this? when reading/writing a file, if there are APC's, the reading/writing returns immediately and prematurely, and the APC's are executed.
