Hi.
There are many ways to display pdf's files. Most of them will rely on 3rd party compenents. The most common way in latest versions of pb 2019 is using webcontrol.
You have to place a webcontrol on a window. Let say that your pdf to display is: "c:\MyPDFs\abcd.pdf". Also let say that your web control is called wb_1.
To load it to the webcontrol you need to give the following command:
wb_1.navigate("file:///c:/MyPDFs/abcd.pdf")Pay attention to the change on fullpathname!
That way the file will be loaded to the web control. Unfortunately You cannot know when load is complete.
Another way is to use Adobe Acrobat Reader OLE - active-x control.
In your window you can add it as a control by creating an OLE Control.
A window will show where you will select (acrobat reader must pre-exist on the computer):
With the selected control click on your window at the point you want to place the control.
To load the pdf you call the following command:
ole_1.object.loadfile("c:\MyPDFs\abcd.pdf")I attach a simple pb project that demonstrates both solutions (PB 2019 R3 2779).
Andreas.

It's not clear to me from the PB Documentation how to open a pdf file in a web browser using HttpClient object?

Since the Inet object can be used for several different purposes, it is possible that the HTTPClient object is the suggested replacement only for some of the Inet object's functionality, not all. I wish the documentation was a little more helpful in this regard. I've seen your follow-up question, so we'll see what others say in response to that.

I agree with John, "obsoleted" features aren't removed, they just aren't supported. My code is 26+ years old, and whenever I upgrade PB, I do get Warnings that a certain function/object/etc. is obsolete, but it still works. I've recently cleaned up all of those, except maybe now the iNet object! Sometimes, "if it ain't broke, don't fix it!"
