The SDK reference for IStorage::CreateStream[^] is quite clear that pwcsName must not exceed 31 characters. Just use a short version of the file name (<= 31 chars long,) and put the real file name length as the first thing in your stream, and the actual name right after. When "walking" the streams in your storage, you can always read in the length and the actual file name from each stream.
Assuming your file name, strFileName, is an STL string, you can:
ULONG nLen = strFileName.length();
ULONG cbWritten = 0;
pIMyStream->Write(reinterpret_cast<void*>(&nLen), sizeof(ULONG), &cbWritten);
pIMyStream->Write(reinterpret_cast<void*>(strFileName.c_str()), nLen, &cbWritten);
And
ULONG nLen = 0;
ULONG cbRead = 0;
pIMyStream->Read(reinterpret_cast<void*>(&nLen), sizeof(ULONG), &cbRead);
char* pszBuf = new char[nLen + 1];
memset(pszBuf, 0, nLen + 1);
pIMyStream->Read(reinterpret_cast<void*>(pszBuf), nLen, &cbRead);
strFileName = pszBuf;
delete [] pszBuf;
Or something like that...

I would like to know how one determines the state of all keys pressed when OnKeyDown is triggered in a MFC dialog. I need this to do a special key combination that only I will have access too while developing the application. Specifically "s" and "+" as well as "s" and "-"
Thanks,
Clint

Try looking at either one of these API functions:
GetAsyncKeyState
GetKeyboardState

You can do something like this in your OnKeyDown handler:
if( nChar == _T('S') || nChar == _T('s') )
{
if( GetKeyState( _T('+') ) & 0x10000000 )
{
}
else
if( GetKeyState( _T('-') ) & 0x10000000 )
{
}
}

Does anybody know, which image format is supported by ListCtrl ? I create CImageList from resource. I tried do put there 32-bit bitmap, 8 bit indexed bitmap, but there always was an problem with colors - some colors in image was changed. When i use standard colors in VC++ bitmap editor, it's ok, but i need to use non-standard colors. Any idea how to do that ?
Thanks.

1) Make sure you're not editing the bitmap in Visual Studio; it won't work for 32bit images, and generally chokes badly on anything better than 4-bit color...
2) The normal MFC code to load a bitmap from resources doesn't work on high-color images. You can use either of the following techniques to get a bitmap from resources into your image list (we'll assume the resource ID is IDB_MY_IMAGES, and you want it split into 6 16x16 pixel images with no transparency):
CImageList MyImageList;
MyImageList.Attach(ImageList_LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDB_MY_IMAGES), 16,0,
CLR_NONE, IMAGE_BITMAP, ILC_COLOR32));
or:
CImageList MyImageList;
MyImageList.Create(16,16,ILC_COLOR32,0,6);
CBitmap bmpTmp;
bmpTmp.Attach(::LoadImage(AfxGetResourceHandle(), MAKEINTRESOURCE(IDB_MY_IMAGES),
IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION));
MyImageList.Add(&bmpTmp, NULL);

Thank you very much ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif) !
The first solution didn't work - it did exactly what standard
imageList.Create(IDB_MAILSTAT,16,1,RGB(255,255,255));
but second solution is working !

is it fast, reliable? What are the cases it is must suitable for and what
are the cases it shouldn't be used?
Thanks a lot!

I am using pipes for comunicate threads in a security system And I never had problems with that...

It's a terrible, and extremely inefficient, way to communicate between threads. A semaphore based queue will be the most efficient general solution. If complex synchronization isn't needed, or we're talking just mainting state information, using CriticalSections or the Interlocked... calls is sufficient.
|

Name pipe is a good solution for communication between multiple processes. For communication between threadings I recommend CRITICAL_SECTION, mutex, event, and sephamore.

I have an MDI application with a view class .
The View class is derived from CFormView and contains a CTreeCtrl and an MSFLExgrid.
Whenever I change the size of the Frame that contains the view , I want the controls inside the view to also resize.
I have included OnSize method in the View class that makes a call to
CFormView::OnSize
What else should i be doing to resize the controls of the FormView ?
Please Help
|

Hello!
Calling the CFormView::OnSize function won't resize the form view, you have to do it yourself. This is because the OnSize function is merely a handler for when the form view gets resized.
Here is what you want:
(inside your OnSize method in the view class)
<br />
CRect rc;<br />
GetClientRect(rc);<br />
m_yourFormView->MoveWindow(rc);<br />
That code will resize the form view to fit your entire view. You might need to then add code to resize the tree control and MSFlexGrid inside the form view. In order to do that, you probably want to look at some layout managers in the Dialog & Windows section of CodeProject.
Hope that helps!
Sincerely,
Alexander Wiseman

Any one knows how to use complex class in VC++? How to declare it and how to use it? Thanks.

Hi!
Can I use CFileDirectory to select one directory and not a file?
How?
/Ola Carlsson

You can use SHBrowseForFolder.
You can also simply let the user select a file, but then use only the directory portion of the path.
Even a broken clock is right twice a day.

Hi,
I am building software that uses the audio devices in windows.
While my program is running it is very inconvinient to have the users sound theme working (small clicks etc when opening folders and such).
Is there any way to turn that off when my program is running. I would like a way to turn it on again after my application shuts down.
Any hints?
Brest regards

Hello All,
In my project, I am using IStorage::CreateStream(). What I am doing is creating storage, and adding a file into the stream. For that I am using CreateStream, but the problem is, if the file name is large my program is crashing. I read MSDN, that CreateStream can't handle large filename (more than 31 characters.) Its giving me an error invalid pwcsName.Is there anyway to handle this problem???
Or is there any alternative which can solve this problem. Please, help.
Thanks,
