VBA send XMLHttpRequest from Internet Explorer

Question

tl;dr: How can one send a POST request in VBA by using an XMLHttpRequest within the Internet Explorer?

---

I'm about automating the use of page on the internet. The idea is to start from Excel to gather some data in a worksheet, then transfer these data to the internet page, click some buttons in the meantime, and thereafter work on manually.

I recorded the whole process when executed manually by the F12 Developer tools. By bringing the data into the textboxes of the internet page, some Javascript events take place which fire a POST request through XMLHttpRequest:

Now, by replicating the procedure described above in VBA (using getElementById , .click() , .value= and the like), it appears that the relevant events are not fired: no such POST request as shown above are sent to the server, and no additional masks open. This is why I wanted to omit the textbox-filling-and-clicking approach and simply replicate the POST request.

How can I do this from VBA by using the Internet Explorer?

Disclaimer: I'm aware how to send a POST request using MSXML2.serverXMLHTTP , which is described hundreds of times over the web. However, there it's always either-or: either use the Internet Explorer, or MSXML2.serverXMLHTTP . However, I need the request within the Internet Explorer.

Answer 1

These links looks promising | VB5 | C# | Navigate method, 4th argument | Another VB example using StrConv for byte array conversion | It looks like you simply use the Navigate method and simply data packed into a byte array for the fourth argument. One of the above links is old but the newer link looks very similar so I think the interface has not changed much.

Do please post feedback.
