Clipboard getdata code#
Sir I have test your code copying in separate winform application application and it worked but when i copy your code in my project where i am facing the NULL problem then i still i am getting the NULL issue over there.Ī code which works in another winform application and the same code not working in my project.very confused and not being able to capture the reason why this return NULL return retrievedData. Set a breakpoint on your get/set code and make sure it is working properly. So the problem is most likely the data you're adding to `Tag`. Return retrievedData.GetData(typeof(NodeCollection)) as NodeCollection Example Clipboard.SetData Picture1.Picture ' or Clipboard.SetData LoadPicture('d:\mypic. The SetData method places data e.g an image in clipboard. Example Text2.Text Clipboard.GetText The SetData method. If (retrievedData.GetDataPresent(typeof(NodeCollection))) The GetTex method lets you retrieve the text which is in clipboard. Var retrievedData = Clipboard.GetDataObject() Private static NodeCollection GetClipboardData() Private static void SetClipboardData ( NodeCollection nodeCollection ) NodeCollection ndCollection = new NodeCollection() įoreach (TreeNode node in selectednode.Nodes) Private void BtnSet_Click(object sender, EventArgs e) please have a look and tell me where i made the mistake and what to change in code as a result i should be able to retrieve the object i stored in clipboard. i am not being able to find out where i made the mistake. If you need a finer degree of control over retrieving data from the clipboard, you may want to use the _ClipBoard_GetDataEx() function.I have store the instance of my class in clipboard and when retrieve the same from clipboard then getting null always. I'm using Clipboard. It checks to see if the data format is available, opens the clipboard, closes the clipboard and returns the data in one of two formats: String format for datatypes $CF_TEXT, $CF_OEMTEXT, or $CF_UNICODETEXT, or Binary format for every other type. Because of security restrictions, this method. In Firefox, Opera, Google Chrome and Safari, use the execCommand method with the 'Paste' command to retrieve and with the 'Copy' command to set the text content of the clipboard. This function performs all of the steps neccesary to get data from the clipboard. In Internet Explorer, use the getData method to retrieve and the clearData method to clear the contents of the clipboard. Text for text based formats or Binary data for all other is set to the # of characters for Text, or # of bytes for Binary $CF_DSPENHMETAFILE - Enhanced metafile display format associated with a private format $CF_DSPMETAFILEPICT - Metafile picture display format associated with a private format $CF_DSPBITMAP - Bitmap display format associated with a private format However, if you retrieve file content, Clipboard.GetData returns a byte array wrapped by that variant. When retrieving just plain text it is just a wrapped string that can be converted straight to a string by simple assignment, as shown above. $CF_DSPTEXT - Text display format associated with a private format Please note, the Clipboard.GetData method returns a variant. $CF_DIBV5 - BITMAPV5HEADER structure followed by bitmap color and the bitmap bits $CF_LOCALE - Handle to the locale identifier associated with text in the clipboard $CF_HDROP - Handle to type HDROP that identifies a list of files $CF_ENHMETAFILE - Handle to an enhanced metafile (HENHMETAFILE) $CF_WAVE - Represents audio data in WAVE format $CF_RIFF - Represents audio data in RIFF format $CF_PENDATA - Data for the pen extensions to Pen Computing $CF_DIB - BITMAPINFO structure followed by the bitmap bits $CF_OEMTEXT - Text format containing characters in the OEM character set
