No need for a P/Invoke, you can just use the Process.GetProcesssesByNam<wbr />e method:<br />

The disadvantage is that you do not know which instance of Word would be the one you're looking for, unless you run it under a specific account.

Hi,<br />
<br />
I have a hidden Word process in the background. &nbsp;I need the ProcessID &nbsp;which I can get from &nbsp;GetThreadProcessID() if I have the HWND. &nbsp;Excel has an Hwnd variable as does PowerPoint. &nbsp;But...not Word. &nbsp;None that I could find unless it is hidden deep down inside some class. &nbsp;<br />
<br />
The problem with FindWindow is they may have other versions of Word running so I wouldn't know if its the one I just launched hidden.<br />
<br />
Any ideas would be appreciated..<br />

Hi,

I have a hidden Word process in the background.  I need the ProcessID  which I can get from  GetThreadProcessID() if I have the HWND.  Excel has an Hwnd variable as does PowerPoint.  But...not Word.  None that I could find unless it is hidden deep down inside some class.  

The problem with FindWindow is they may have other versions of Word running so I wouldn't know if its the one I just launched hidden.

Any ideas would be appreciated..





C# Word Automation:  Need process ID or Hwnd

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

Microsoft Word is a commercial document editing program that is part of the Microsoft Office suite. It features numerous text-editing tools for creating richly formatted documents, along with tools for the use of macros in Word documents. Word's native file formats are denoted either by a .doc or .docx file extension. Plugins permitting the Windows versions of Word to read and write formats it does not natively support, such as the OpenDocument format (ODF) are available. Word can import and display images in common bitmap formats such as JPG and GIF. It can also be used to create and display simple line-art.
