Title, no changes to existing Windows Form apps,
from external processes
We are investigating how to access (enter and load if possible) any cells in DataGridView of the Windows Form app.
The environment is Windows 10 for OS and 4.5.2 for .NET.
With Windows Message, you can access TextBox and Button. I have confirmed it (using SendMessage as follows).
[DllImport("user32.dll", SetLastError=true)]
public static external int SendMessage (IntPtrWnd, int msg, intwParam, intlParam);
However, I do not know how to access any cells in DataGridView.
If you have any know-how around here, please let me know whether you can access it or not.
Thank you for your cooperation.
It seems to have been made with a software called UWSC that automates Windows operations.
However, I am currently out of touch with the author, and the site seems to be in a state of collapse.

There is a similar article in the English version, and although there is no resolution mark, there are answers with prize points.

This article is more similar, but it uses the same software called AutoIt as UWSC.
However, there is no resolution mark here either.
C#-Read datagridview of some application
DataGrid, the predecessor of DataGridView, seems to be able to access it using a feature called UI Automation, but DataGridView is not directly supported.
It seems that the answers in the English version above are written that both of them can be done with some ingenuity.
Support for DataGrid controlled with UI automation and D with UI automationIt may be a combination of ataItem controlled support.

In an old Python article, there was an introduction to a tool that could be used interactively.

For example, VSC 2017 seems to be around here.
"C:\Program Files (x86)\Windows Kits\10\bin\10.0.17763.0\x64\inspect.exe"
"C:\Program Files (x86)\Windows Kits\10\bin\10.0.17763.0\x64\UIAVerify\VisualUIAVerifyNative.exe"
Under "Windows Kits", there are multiple folders with the same name, depending on the number of Windows versions, SDK versions, .NET versions, CPU bits, architecture, and so on.

Originally designed to automate UI testing, you can "get/set the value of any control in the external process" depending on how you do it.
Install the following two items on NuGet and you can use them at a minimum.
When updated to .NET Framework 4.8 released today, the DataGridView also appears to support, UI Automation.According to the announcement,
Currently the accessible hierarchy (UI Automation tree) shows the editing box tree element as a child of currently edited cell but not as a root child element of DataGridView.
Therefore, it was already handled, and in 4.8 it was improved so that the hierarchical structure of the cell being edited could be obtained correctly.
When I tried displaying it in Inspect.exe included in the Windows SDK, I was able to get the display even before the .NET update.
Therefore, it seems that the direct attack method is to get it with UI Automation.
