问题 i want to make dll that using tform as parameter, the simple plan is if that form passed to dll the dll file return array that contain components name. it possible to passing tform as parameter? 回答1: Most likely you will have two instances of the VCL in your process, one for the host exe and one for the DLL. And that is one instance too many. The TForm class from your host exe is a different class from the TForm class in your DLL. The basic rule is that you cannot share VCL/RTL objects across

问题 I have a dynamic HTML form with three fields (item, number, cost). Users can add as many rows as they need. Because of this, I have set the fields names as item[], number[], cost[] in order to loop through the post and insert the values in the DB. I have verified that the values are posted correctly up correctly through vardump, and I have checked that the following loop is picking up the values (both key and value) through printr. (and also simply echoing $value1). foreach ($_POST as $field

问题 This is probably a really easy question, but I actually haven't seen many search results on this. I have a very basic submit button within a form that takes some user input, and generates a downloadable file in the server's temp directory, then prompts the user to download this file, which is then disabled by this on submit: <form action="Home" method="post" onsubmit="Submit.disabled = true; return true;"> ... <input type="submit" name="Submit" value="Submit" id="Submit" /> We need it to be

问题 Does Delphi provide some kind of event or hook for form creation (or more generally, form lifecycle events)? So that if somewhere in the code a form is created and shown (modal or non-modal, dynamically or in the usual app starup stage), Delphi calls an event handler which allows to log / analyse / modify the form before it is shown?
