剪贴板对象 [英] Clipboard object

问题描述

如何从注册数据类型获取clipbaord中的数据。

下面的代码片段不起作用？但是VB6的例子确实如此。

我做错了什么。

private void lstItems_DragDrop（对象发送者，

System.Windows.Forms.DragEventArgs e）


{


//创建一种新的数据格式。


DataFormats.Format myFormat = DataFormats.GetFormat（" myDataType"）;

//创建DataObject接口的新实例。


IDataObject data = Clipboard.GetDataObject（ ）;

lstItems.Items.Add（data.GetData（myFormat））;


}


In VB6这个工作，这看起来很简单。


私有子Text2_OLEDragDrop（数据为数据对象，效果为长，按钮为

整数，Shift为整数， X单身，Y单身）

My_Format = RegisterClipboardFormat（" myFormat"）

Dim a（）As Byte

a =数据。 GetData（My_Format）


MsgBox a

End Sub

解决方案

你好罗u，


Drag& Drop不使用剪贴板。所以，如果你检查剪贴板，就像你做的那样，你可能会找到一些东西，但它可能不会是你想要的b $ b。而不是阅读剪贴板使用

DragEventArgs参数的Data属性。您必须使用IDataObject来获取您拖动的数据

。

私有Sub Text2_OLEDragDrop（数据为DataObject，效果为长，按钮
As Integer，Shift As Integer，X as Single，Y as Single）
My_Format = RegisterClipboardFormat（" myFormat"）
Dim a（）As Byte
a = Data.GetData （My_Format）

MsgBox a
End Sub

你能举个例子吗？

这将非常有帮助。

我正在努力克服来自VB的C＃。

嗨楼，

拖放不会使用剪贴板。因此，如果你检查剪贴板，就像你做的那样，你可能会在那里找到一些东西，但它可能不会是你所期望的。而不是读取剪贴板使用
DragEventArgs参数的Data属性。您必须使用IDataObject来获取拖动的数据。

我如何获得clipbaord中的数据来自已注册的数据类型。
下面的代码片段不起作用？但是VB6的例子确实如此。

private void lstItems_DragDrop（object sender，
System.Windows.Forms.DragEventArgs e）

{

//创建一种新的数据格式。

DataFormats.Format myFormat = DataFormats.GetFormat（" myDataType"）;

//创建DataObject接口的新实例。

IDataObject data = Clipboard.GetDataObject（）;

lstItems.Items.Add（data.GetData（myFormat））;



在VB6中这个工作，这看起来很简单。

Private Sub Text2_OLEDragDrop（Data As DataObject，Effect As Long，Button

As

Integer，Shift As Integer，X as Single，Y as Single）
My_Format = RegisterClipboardFormat（" myFormat"）
Dim a（ ）作为Byte
a = Data.GetData（My_Format）

MsgBox a
End Sub

这个窝rks标准文本但不是我的注册格式？

如果我从wordpad拖动文本它可以工作，但不能从我的其他应用程序中删除

" CF_MOSCtrlData" ????

private void lstItems_DragDrop（对象发送者，

System.Windows.Forms.DragEventArgs e）


{


//创建一种新的数据格式。

DataFormats.Format myFormat = DataFormats.GetFormat（" CF_MOSCtrlData"）;


if（e.Data.GetDataPresent（typeof（System.String）））


{


Object item =（object）e.Data.GetData（typeof（System.String））;


lstItems.Items.Add（item）;

Debug.WriteLine（" Data preesent"）;


}

MsgBox a
End Sub

How do I get the data in the clipbaord fro a registered data type.
The code snippet below doesn''t work? But the VB6 example does.
What am I doing wrong.
private void lstItems_DragDrop(object sender,
System.Windows.Forms.DragEventArgs e)

{

// Creates a new data format.

DataFormats.Format myFormat = DataFormats.GetFormat("myDataType");
// Create a new instance of the DataObject interface.

IDataObject data = Clipboard.GetDataObject();
lstItems.Items.Add (data.GetData(myFormat));

}

In VB6 this DOES work, this seems very simple.

Private Sub Text2_OLEDragDrop(Data As DataObject, Effect As Long, Button As
Integer, Shift As Integer, X As Single, Y As Single)
My_Format = RegisterClipboardFormat("myFormat")
Dim a() As Byte
a = Data.GetData(My_Format)

MsgBox a
End Sub

解决方案

Hi Lou,

Drag&Drop doesn''t use the clipboard. So if you check the clipboard, as you
do, you might find something there, but it probably won''t be what you
expect. Instead of reading the clipboard use the Data property of the
DragEventArgs parameter. There is the IDataObject you have to use to get
your dragged data.

Can you give me an example?
That would be very helpful.
i am struggling with C# comming from VB.

This works with standard text but not with my registered format?
if i drag text from wordpad it works but not from my other app that drops
"CF_MOSCtrlData" ???

private void lstItems_DragDrop(object sender,
System.Windows.Forms.DragEventArgs e)

{

// Creates a new data format.

DataFormats.Format myFormat = DataFormats.GetFormat("CF_MOSCtrlData");

if (e.Data.GetDataPresent(typeof(System.String)))

{

Object item = (object)e.Data.GetData(typeof(System.String));

lstItems.Items.Add (item);

Debug.WriteLine ("Data preesent");

}
