How do I get the Windows Handle of an ActiveDocument in Microsoft Word?
I wish to save the handle value to a variable.
You can use the FindWindow function to get the handle of the window in a currently active word application:
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
(ByVal lpClassName As String, ByVal lpWindowName As String) As Long
The class name for MS Word is "OpusApp". If you have only the one Word app open then the following would return the handle to that window:
Public Function Test1()
Dim lhWnd As Long
lhWnd = FindWindow("OpusApp", vbNullString)
End Function
Note when you have multiple active Word applications, you can add the name of the window caption. For example if its saved as "Stanigator.doc", then the caption would read as "Stanigator - Microsoft Word". So:
Public Function Test2()
Dim lhWnd As Long
lhWnd = FindWindow(vbNullString, "Stanigator - Microsoft Word")
End Function
The other API that may come in handy is:
Private Declare Function GetActiveWindow Lib "user32" () As Long
Edit:
I was going to recommend the VSTO approach but based on this link that doesn't appear to be wise:
Connect Issue: VSTO API support for MS Word Main Window Handle
As Tim Williams pointed out, it's Set myDoc = ActiveDocument.

I have an ms access vba code from which i wish to copy some text value to the Windows clipboard so that I can paste it elsewhere (Word/Excel/Notepad/etc).
I have been searching for this in SO but everything seems over-complicated.
Should it not be something simple like
clipboard.SetText textValue
?
EDIT
I tried following the hint by BrianMStafford but don't succeed. Perhaps the reason is that my object is a node in a tree.
When I do
MsgBox Me.NodeKey.Value
it all works fine - I see the node path in the message box.
But when I do
Me.NodeKey.SetFocus
DoCmd.RunCommand acCmdCopy
I don't get the node path in the clipboard
So how can I copy the node path value into the Windows clipboard?
It should be as simple as you say, however Access for some reason doesn't have the same "options" as excel. You have to add it manually or use Cristian Buse's answer which is pretty much the same, he is skipping adding the reference. So here is the way to manually add the reference to use .SetText in Access.
Access does not have the MS Forms listed on the Reference table like Excel (dont ask me why), but you can Browse to the file location and add it manually:
After you add this manually you can use the .SetText anywhere as long as you also declare the object of course.
Sub testCopy()
Dim clipOb As MSForms.DataObject
Set clipOb = New MSForms.DataObject
clipOb.SetText Format(Now(), "m/d/yyyy")
clipOb.PutInClipboard
End Sub
Now you can paste it anywhere. Just replace Format(Now(), "m/d/yyyy") with your Me.NodeKey.Value. If your Value is empty/blank it will give you an error, so just do a check before using .SetText to make sure you have a value to set.
Use Windows API to Set Clipboard Data.
Here's the documentation page:
https://learn.microsoft.com/en-us/office/vba/access/concepts/windows-api/send-information-to-the-clipboard
Here's the code required with 2 example of how to use.
After running sub to save data to clipboard, just paste it anywhere.
Option Explicit
Private Declare Function OpenClipboard Lib "user32.dll" (ByVal hWnd As Long) As Long
Private Declare Function EmptyClipboard Lib "user32.dll" () As Long
Private Declare Function CloseClipboard Lib "user32.dll" () As Long
Private Declare Function SetClipboardData Lib "user32.dll" (ByVal wFormat As Long, ByVal hMem As Long) As Long
Private Declare Function GlobalAlloc Lib "kernel32.dll" (ByVal wFlags As Long, ByVal dwBytes As Long) As Long
Private Declare Function GlobalLock Lib "kernel32.dll" (ByVal hMem As Long) As Long
Private Declare Function GlobalUnlock Lib "kernel32.dll" (ByVal hMem As Long) As Long
Private Declare Function lstrcpy Lib "kernel32.dll" Alias "lstrcpyW" (ByVal lpString1 As Long, ByVal lpString2 As Long) As Long
Public Sub SetClipboard(sUniText As String)
Dim iStrPtr As Long
Dim iLen As Long
Dim iLock As Long
Const GMEM_MOVEABLE As Long = &H2
Const GMEM_ZEROINIT As Long = &H40
Const CF_UNICODETEXT As Long = &HD
OpenClipboard 0&
EmptyClipboard
iLen = LenB(sUniText) + 2&
iStrPtr = GlobalAlloc(GMEM_MOVEABLE Or GMEM_ZEROINIT, iLen)
iLock = GlobalLock(iStrPtr)
lstrcpy iLock, StrPtr(sUniText)
GlobalUnlock iStrPtr
SetClipboardData CF_UNICODETEXT, iStrPtr
CloseClipboard
End Sub
Sub Example_SetClipboardData_1()
SetClipboard "Hello World"
End Sub
Sub Example_SetClipboardData_2()
Dim TextVar As String
TextVar = "Hello again, World"
SetClipboard TextVar
End Sub
Public Sub WriteToClipboard(ByVal text As String)
CreateObject("htmlfile").ParentWindow.ClipboardData.SetData "text", text
End Sub
Example usage:
WriteToClipboard "test"
Edit #1
The above seems to work in Excel just fine. I only managed to make it work in Access for a specific computer. Once tested on another computer I got an error 70 (access denied).
The below only works in Excel if Windows Explorer is closed. However, it seems to work fine in Access regardless if Explorer is open/closed:
Public Sub WriteToClipboard(ByVal text As String)
With CreateObject("new:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}") 'MsForms.DataObject
.SetText text
.PutInClipboard
End With
End Sub
When googling the object code that Cristian posted, I found a good page listing the possibilities, both early and late binding. Hence this page combines the answers by Christian Buse and Ricardo A.

I am trying to find a specific window-class and want to send a custom message to it via a DNS command. I have trouble locating the window.
This is a working example for Notepad:
Declare Function FindWindow Lib "USER32" _
(ByVal lpszClassName As String, ByVal lpszWindow As String) As Long
Sub Main
Dim hWnd As Long
hWnd = FindWindow("Notepad", "Unbenannt - Editor") '<-- german title; change it
Debug.Print CStr(hWnd)
End Sub
However, It will not find the handle if I use the following:
hWnd = FindWindow("Notepad", vbNullString)
And I think it should. Here is the MSDN-Entry for it. It states, that the window name is optionally. Am I missing something?
I think that getting the window name is not an option in my case, as the target is an rich-edit-control which will not have a static window name as it send it's content rather than a static title (which is standard behavior). So I need to get this to work wthout supplying a window name.
I'm trying to log into a website and then upload some photos but I'm not getting any further. When the dialog opens, I can't control it programmatically. I tried to define an object as FileDialog and also to use the Application.SendKeys but it seems that the dialog isn't an application.
Hello my code is like this :
1.I define an obj as internetexplorer.aplication
2.I login and then I want to upload a photo so I click the button for upload
' all works till now
3.Now I try to interact with the dialog that let's me to choose the photos programmatically and their is my problem
Thank you Paul i'll try it today out!
Best Regards

You'll have to use a browser object with code similar to this:
.
Set browser = CreateObject("InternetExplorer.Application")
browser.Visible = True
brwser.navigate "http://stackoverflow.com/..." 'your address
Sleep 1000 'wait for 1 second
With browser.Document
Set txtUsr = .getElementsByName("Username")
Set txtPass = .getElementsByName("UserPass")
Set btnLogin = .getElementById("btnLogin")
End With
txtUsr.innerText = "User Name"
txtPass.innerText = "Password"
btnLogin.Click
.
and so on...
Use DOM, and try to avoid SendKeys if possible
"Sleep" uses an API that can be declared at the top of the module like this:
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
.
Edit: I noticed that you are actually trying to interact with a dialog box, not a browser page. If so, you'll need to use Windows API functions to be able to first identify it from VBA; I'd suggest using "FindWindow":
Private Declare Function FindWindow Lib "User32" Alias "FindWindowA" ( _
ByVal lpClassName As String, _
ByVal lpWindowName As String _
) As Long
and call it from VBA like this:
setMyDialog = FindWindow(vbNullString, dialogCaption)
then send keys to it; you can send the "Tab" key to move from one text box to the next
If the website is using this dialog to allow you to select multiple images it will be more challenging to automate; you'll have to use other recordings methods to simulate multiple file selections or drag-and-drop actions with the mouse
Here are some links that can help with API functions:
How To Get a Window Handle Without Specifying an Exact Title (microsoft.com)
API Declarations for VB and VBA (microsoft.com)
stackoverflow.com/questions/25098263/ (How to use FindWindow)
.
Edit for your 3 questions:
"I get an error when i use the function. Something with the 64-bit system..." - you have a 64 bit version Excel so replace this declaration
.
Private Declare Function FindWindow Lib "User32" Alias "FindWindowA" ( _
ByVal lpClassName As String, _
ByVal lpWindowName As String _
) As Long
with this one:
Private Declare PtrSafe Function FindWindow Lib "user32" Alias "FindWindowA" ( _
ByVal lpClassName As String, _
ByVal lpWindowName As String
) As LongPtr
.
"When i copy the function VBA says that only comments may appear after End Sub..."
This is a declaration so it must be placed at the top of the module (before any other functions)
What should I write instead of "vbNullString" and "dialogCaption"??
You can still use "vbNullString" as the first argument, but you have to replace "dialogCaption" with the title of your dialog box
do not use quotation marks for vbNullString
do use quotation marks for the title of the dialog
I'm trying to Close the OneNote Application from VBA excel with this piece of code:
Sub closeOneNote()
Dim oneNoteApp As Object
On Error Resume Next
Set oneNoteApp = GetObject(, "OneNote.Application")
If Err.Number = 0 Then
oneNoteApp.Quit
Else
Err.Clear
End If
End Sub
When I try with Outlook instead of OneNote, it works fine and Outlook closes. I was wondering if it was because OneNote is not an application that supports automation through VBA. As shown in the below link, the table at the bottom of the page lists all the top-level Office objects Ican reference and their class names and OneNote is not among them:
Creation of Object Variables to Automate Another Office Application
Any ideas, suggestions on how to close the application (not the notebooks themselves, only the application running.. )
Thanks
Here is a good resource for handling NoteNote:
http://msdn.microsoft.com/en-us/library/hh377180(v=office.14)
and in general:
http://msdn.microsoft.com/en-us/library/hh377180(v=office.14)
OneNote Application interface (documented here) does not have a Quit method. That is why it won't work. What you can do instead is to close the OneNote window, which is somewhat tricky. Here are some instructions and sample code:
Get the OneNote window handle: The application object has a CurrentWindow member which then has a WindowHandle member that is a HWND to the current OneNote window.
Get the top level window: This handle is typically a child window of the OneNote window so you need to call GetAncestor with GA_ROOT to get the top level window
Close the window: You can send WM_CLOSE to the top level window to close it. Of course if it is displaying a dialog box or busy in another way, it may not respond to this.
Option Explicit
Private Declare PtrSafe Function PostMessage Lib "user32" Alias "PostMessageA" _
(ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Declare PtrSafe Function GetAncestor Lib "user32.dll" _
(ByVal hwnd As Long, ByVal gaFlags As Long) As Long
Private Const GA_ROOT As Long = 2
Private Const WM_CLOSE = &H10
Sub test()
' Create Application Object
Dim app As Object
Set app = CreateObject("OneNote.Application")
' Get the window handle
Dim hwnd As Long
hwnd = app.Windows.CurrentWindow.WindowHandle
' Get the top level window
Dim hwndRoot As Long
hwndRoot = GetAncestor(hwnd, GA_ROOT)
' Close it
PostMessage hwndRoot, WM_CLOSE, 0&, 0&
End Sub
This won't be enough if there are multiple OneNote windows around. For that case you can enumerate the Windows collection and do this for each Window object in it.
I am developing an application which opens and reads an XML document previously embedded in a PowerPoint presentation, or a Word document. In order to read this object (xmlFile as Object) I have to do:
xmlFile.OLEFormat.DoVerb 1
This opens the package object, and I have another subroutine that gets the open instance of Notepad.exe, and reads its contents in to ADODB stream.
An example of this procedure is available on Google Docs:
XML_Test.pptm.
During this process there is a few seconds window where the Notepad.exe gains focus, and an inadvertent keystroke may cause undesired results or error reading the XML data.
I am looking for one of two things:
Either a method to prevent the user from inadvertently inputting (via keyboard/mouse/etc) while this operation is being performed. Preferably something that does not take control of the user's machine like MouseKeyboardTest subroutine, below. Or,
A better method of extracting the XML data into a string variable.
For #1: this is the function that I found, which I am leery of using. I am wary of taking this sort of control of the users system. ##Are there any other methods that I might use?##
Private Declare Function BlockInput Lib "USER32.dll" (ByVal fBlockIt As Long) As Long
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sub MouseKeyboardTest() 'both keyboard and mouse blocked
BlockInput True ' Turns off Keyboard and Mouse
' Routine goes here
Sleep 5000 ' Optional coding
BlockInput False ' Turns on Keyboard and Mouse
End Sub
For #2: Some background, but the issue seems to be the inability to extract the embedded object reliably using any method other than DoVerb 1. Since I am dealing with an unsaved document in an application (Notepad) that is immune to my VBA skillz, this seems to be the only way to do this. Full background on that, here:
Extracting an OLEObject (XML Document) from PowerPoint VBA
As you correctly guessed in the comment above that taking the focus away from notepad will solve your problem. The below code does exactly that.
LOGIC:
A. Loop through the shape and get it's name. In your scenario it would be something like Chart Meta XML_fbc9775a-19ea-.txt
B. Use APIs like FindWindow, GetWindowTextLength, GetWindow etc to get the handle of the notepad window using partial caption.
C. Use the ShowWindow API to minimize the window

(ByVal lpClassName As String, ByVal lpWindowName As String) As Long

My understanding is that you have control over how XML file gets embedded into PowerPoint presentation in the first place. Here I do not quite understand why you chose to keep the data you need as contents of an embedded object.
To be sure, the task of getting those contents back is not a piece of cake. Actually, as long as there is no (simple or even moderately difficult) way to call QueryInterface and use IPersist* interfaces from VBA, there is just one way to get to contents of embedded object. The way involves following steps:
Activate an embedded object. You used OLEFormat.DoVerb 1 for that. A better way would be to call OLEFormat.Activate, but this is irrelevant for your particular problem.
Use embedded object's programming model to perform useful operations like getting contents, saving or whatever is exposed. Notepad.exe exposes no such programming model, and you resorted to WinAPI which is the best choice available.
Unfortunately, your current approach has at least 2 flaws:
The one you identified in the question (activation of notepad.exe leading to possibility of user's interference).
If a user has default program for opening .txt files other than notepad.exe, your approach is doomed.
If you do have control over how embedded object is created then better approach would be to store your XML data in some property of Shape object. I would use Shape.AlternativeText (very straightforward to use; shouldn't be used if you export your .pptm to HTML or have some different scenario where AlternativeText matters) or Shape.Tags (this one is probably the most semantically correct for the task) for that.
I don't think that blocking the user is the right approach,
If you must use a content of a notepad window, I would suggest using the SendKeys method, in order to send this combination:
SendKeys("^A^C")
Which is the equivalent of "Select All" and "Copy",
And then you could continue working "offline" on the clipboard, without fear of interference by keystrokes.
My approach, per Sid's suggestion, was to find a way to minimize the Notepad.exe. Since I already found way to get that object and close it, I figured this should not be as hard.
I add these:
Public Declare Function _
ShowWindow& Lib "user32" (ByVal hwnd As Long, _
ByVal ncmdshow As Long)
Public Const SW_MINIMIZE = 6
And then, in the FindNotepad function, right before Exit Function (so, after the Notepad has been found) I minimize the window with:
ShowWindow TopWnd, SW_MINIMIZE
