dropping files from Explorer onto a CHROME HANDLE

[xiaoyao]

MAYBE IT'S LIKE WEBVIEW2，OR QT EXE??

web control hwnd:Intermediate D3D Window
exe classname:Chrome_WidgetWin_1

Process path:
"abc.exe" --type=gpu-process --user-data-dir="C:\Users\admin\AppData\app1" --gpu-preferences=UAAAAAAAAADgAAAYAAAAAAAAAAAAAAAAAABgAAAAAAAwAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAEgA AAAAAAAASAAAAAAAAAAYAAAAAgAAABAAAAAAAAAAGAAAAAAAAAAQAAAAAAAAAAAAAAAOAAAAEAAAAAAAAAABAAAADgAAAAgAAAAA AAAACAAAAAAAAAA= --mojo-platform-channel-handle=1700 --field-trial-handle=1784,i,17425394976030928647,15251993890451894824,131072 --disable-features=SpareRendererForSitePerProcess,WinRetrieveSuggestionsOnlyOnDemand /prefetch:2

SEND MESSAGE WM_DROPFILES，No drag-and-drop file event was generated on the web page

szFileName = StrConv(File1, vbFromUnicode)
 Call GetWindowThreadProcessId(HWND, dwPid)
        hProc = OpenProcess(&H8& + &H20&, False, dwPid)
        If hProc Then
            pmem = VirtualAllocEx(hProc, 0&, dwBuffSize, MEM_COMMIT, PAGE_READWRITE)
            If pmem Then
                Debug.Print pmem
                If WriteProcessMemory(hProc, pmem, pBuff(0), dwBuffSize, 0&) Then
                    'Call SendMessage(hWnd, WM_DROPFILES, pmem, ByVal 0&)
                    Call PostMessage(HWND, WM_DROPFILES, pmem, ByVal 0&)

Want to simulate the mouse drag and drop event, perhaps only like a human to operate? Open the Explorer, or add an Explorer control on the VB6 software to display a PNG file, and then click the file, and then drag and drop to another process.
The process may display a WEBVIEW2 web control that accepts file drag-and-drop events in parts of the page.
Analog mouse operation, will occupy the entire computer, it can not work normally.

WebDriver driver = new FirefoxDriver();
driver.get("https://www.example.com");

WebElement fileInput = driver.findElement(By.id("fileInput"));

Actions actions = new Actions(driver);
actions.moveToElement(fileInput).build().perform();  // Move the mouse over the Upload button

File file = new File("path/to/file.txt");
String filePath = file.getAbsolutePath();  // Get the absolute path of the file

actions.dragAndDropBy(fileInput, 0, 0).build().perform();  // Drag the file to the upload button
actions.release().build().perform();  // Release the file

fileInput.sendKeys(filePath);  // Use sendKeys to upload the file

The above code will open a web page in the browser, and then simulate the user to drag and drop the file onto the upload button with the id "fileInput". Move the mouse over the upload button using the moveToElement method of the Actions class and drag the file over the upload button using the dragAndDropBy method. Finally, release the file using the release method and upload the file using the sendKeys method.

Sum up
In this article, we have shown how to simulate HTML5 drag-and-drop operations in Selenium Webdriver. By using the dragAndDrop method of the Actions class, we can simulate user drag-and-drop operations in automated tests. At the same time, we also showed how to simulate drag-and-drop file operations to meet different testing requirements. I hope this article will be helpful to developers using Selenium Webdriver for HTML5 drag-and-drop simulation.

var dropHandler = function(e) {
e.preventDefault();  // Get the file list
var fileList = e.dataTransfer.files;
// Detects whether a file is dragged to the page
if (fileList.length == 0) {
return;
}
// Check whether the file is a picture
if (fileList[0].type.indexOf("image") === -1) {
return;
}
// Instantiate the file reader object
var reader = new FileReader();
var img = document.createElement("img");
reader.onload = function(e) {
img.src = this.result;
oDragWrap.appendChild(img);
};
reader.readAsDataURL(fileList[0]);
};

It's VB.NET but should be easy enough to translate to VB6, just be careful with the INPUT stuff, search for existing threads on that as it's a little tricky.

This is almost 100% correct, the rest is a matter of luck, thank you very much.
I can't get a message at all with SPY++ or something, for some reason.

Hello, I was able to do it with SHDoDragDrop and a timer calling mouse_event MOUSEEVENTF_LEFTUP
