If all you require for pleasure is an answer, I could have said, "The weather is warm today." What kilt provided you was about as helpful. Check his post history. He's just consuming space.

I use the vfw library to create an avi file.

1)AviInit
2)AviFileOpen
3)AviFileCreateStream
4)AviStreamSetFormat
5)loop(AviStreamWrite)

Now before I close the avifile i want to change the frame rate. I change the dwRate of AviStreamInfo and then call EditStreamSetInfo. This returns error code:-2147467262.

If I dont call EdiStreamSetInfo and continue with closing the avi file it succeeds.

My question is, if is possible to change the frame rate after writing the stream and before closing the file?

Thank You

Populating a TreeView via Drag and Drop from Windows Explorer

Hi All,

I'm having trouble writing code in C++ to populate an empty TreeView with a directory structure derived from dragging and dropping a folder from Windows Explorer. I'd like the folder being dragged to become the root node of the TreeView and all of its subfolders to become the child nodes. I have ItemDrag, DragEnter, and DragDrop event handlers - it's the DragDrop event handler I'm having problems with. I can't get it to actually populate the TreeView, mainly because I'm not sure how to retrieve the information necessary to copy. Any ideas?

Thanks.

Is this using Windows Forms (because the event names sound like Windows Forms names...)?

If so, you might have better luck in the Managed C++/CLI forum[^].

However...first, you need to work out which drop format is the one you need to manipulate. You can get that list from the DragEventArgs object that's passed to your event handler:

private: System::Void treeView1_DragOver(System::Object^  sender, System::Windows::Forms::DragEventArgs^  e)
{
   array<String^>^ formats2 = e->Data->GetFormats();
}

The Data member of the DragEventArgs class also has another method, GetData, that allows you to retrieve the data associated with any one of those formats. You then need to work out how to decipher and use the data for your format (I see one called "Shell IDList Array", which sounds promising). The documentation will come in handy there, as might this CP article[^], which is written in VB.NET, but probably has the detail you need.

Thank you for the reply! I actually managed to get it working using

if(e->Data->GetDataPresent(System::Windows::Forms::DataFormats::FileDrop))
{
  array<String^>^ name = (array<String^>^)e->Data->GetData(System::Windows::Forms::DataFormats::FileDrop);
  // do stuff
}

in the DragDrop event handler. I used this website (it's C#) to help recursively find child nodes.

And my apologies, I did in fact put this post on the wrong board but thank you for taking the time to assist anyways.

On a side note, would you happen to know how to get the aforementioned functionality by dragging folders onto the application icon? Similar to how you can drag an image file onto a photoshop (or similar program) shortcut, then photoshop opens and displays the image you dragged. Thanks.

Those will get passed into a new instance of your application as command-line parameters - full paths to the folders from my brief testing.

Awesome! This worked perfectly. The first command line argument seems to always be the pathname to the executable. All later arguments match up with the folders I dragged onto the icon. For reference, I used

array<String^>^ cmdLineArgs = System::Environment::GetCommandLineArgs();

inside the Form's load event handler to get the arguments.

Thank you again for your help, saved me some major headaches Smile | :)

Yes, that's right.

I tested using the string array passed into main() - that doesn't include the executable pathname (at least in C++/CLI applications - it is included in the main() argument list in native C++ apps).

CString causing problem in mulithreaded , multi processor environment

CString constructor or assingnment or serialization of CString causes the application crash in a multi-processor environment,(this happens in a heavily loaded condition when more than 500 threads are running)
whereas it does not cause any problem in single processor environment.
