Creating a FileSystemObject in VBA: In this section we will deal with two things: Creating a reference of Microsoft Scripting Runtime Library i.e. Scrrun.dll. Excel 2013 often complains that "We couldn't free up space on the clipboard. Another program might be using it right now" when I'm trying to copy cells. Some say it. Open. Clipboard Failed when copy pasting data from wpf Data. Grid. I, too, have been having a problem in an application where I copy information into the clipboard as users peruse a List. Box. The information that's copied is related to the selected item, and it permits them to paste it (said info) into other applications for convenience. Occasionally I get the CLIPBRD_E_CANT_OPEN on some user's systems, but not on others. While I still haven't been able to fix the contention, I was able to create some code to find the application causing the contention. I'd like to at least share this code in the hope it helps someone. I will add the using statement, attributes, and method I created to find the Process object of the culprit. From the Process item you can obtain the process' name, PID, main window title (if it has one), and other potentially useful data. Here's the lines of code I added without the code that calls it. NOTE: Below the code snippet I have one more tidbit to share): using System. Diagnostics; // For Process class. System. Runtime. Interop. Services; // For Dll. ![]() Have you ever tried to copy some cells in Excel and gotten the Cannot empty the clipboard error message? I was recently the victim of this annoying error.![]() Import's. ..[System. Runtime. Interop. Services. Dll. Import("user. Int. Ptr Get. Open. Clipboard. Window(). Dll. Import("user. Set. Last. Error = true)]. Get. Window. Thread. Process. Id(Int. Ptr h. Wnd, out uint lpdw. Process. Id). .. ///- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- . Gets the Process that's holding the clipboard. A Process object holding the clipboard, or null< /returns>. Process Process. Holding. Clipboard(). Process the. Proc = null. Int. Ptr hwnd = Get. Open. Clipboard. Window(). Int. Ptr.

Window. Handle. Proc = proc. }. else if (process. Id == proc. Id). {. Proc = proc. }. return the. Proc. OTHER NOTE: One other thing I changed which simplified my code a bit was to convert from using System. Windows. Clipboard to System. Windows. Forms. Clipboard (see System. Windows. Forms. Clipboard Class)because the latter has a 4- parameter Set. Data. Object() method which includes a retry count and a retry delay in milliseconds. This at least removed some of the retry noise from my code. Your mileage may vary.. I've not yet stumbled upon, so if anyone knows of them please comment. In any event, I hope this proves useful to someone.
