For some reason I can't seem to catch the WM_LBUTTONDOWN event on a label ("STATIC" window). When monitoring with Winspector it appears the message always arrives to the parent window. However, according to the docs, the message should be posted to the Window beneath the cursor. Does anyknow have an idea why the message does not arrive...
It might seem natural to use Ctrl++, Ctrl+-, and Ctrl+0 as shortcuts for an application's zoom in, zoom out, and restore default zoom (typically 100 %) actions. Now, in Delphi, I am able to assign Ctrl++ and Ctrl+0 as shortcuts. The former, though, requires that the plus sign of the main part of the keyboard is used; the plus sign of the...
My understanding is that these functions can be used to serialize a file for backing up and restoring. I'm unclear what they serialize. For example, do they serialize the file attributes (hidden, readonly, etc)? What about the 8.3 name? I do believe they serialize all the file's streams and security options. But what happens when re...

Since pressing Ctrl-C in the application does the right thing, I've been trying to send ctrl-c using my C# application to the other application. Here is my sequence of commands. I compared the messages using S...

For a file or directory, does fully-qulified path exist only one thing? -like canonical path. Are both of them totally same concepts? Edit: One more thin...

If one needs some sort of state in a dialog function, it seems you need some sort of static variable. For example, the hook procedure for GetOpenFileName provides the dialog function with the address of the OPENFILENAME structure on its WM_INITDIALOG call but not on any subsequent calls and the OPENFILENAME structure contains a place fo...
