Preventing undocking a docked form

[vgulielmus]

Unlike the toolbars, a docked form can be undocked.
To prevent that, I cut the window title bar.
Now the docked form cannot be undocked, but only closed.

PUBLIC oFrm
oFrm=CREATEOBJECT("MyForm")
oFrm.show

DEFINE CLASS MyForm as Form

dockable=1
ADD OBJECT cmd as commandbutton

PROCEDURE init

This.Dock(2) && dock to the right side
* cut the title bar so the window can be closed with ctrl+f4 but cannot be moved or undocked
Declare Long SetWindowRgn IN WIN32API Long hWnd, Long hRgn, String bRedraw
Declare Long CreateRectRgn IN WIN32API Long X1, Long Y1, Long X2, Long Y2
SetWindowRgn(thisform.hwnd, CreateRectRgn(0,SYSMETRIC(4)+SYSMETRIC(9)/2,This.width+2*SYSMETRIC(3),This.height+2*SYSMETRIC(4)+SYSMETRIC(9)/2), "True")​

ENDPROC​

ENDDEFINE

My apologies, I'm new on this forum.
I searched everywhere "Helpful Tip", but nothing...until I pressed "Submit Post".
I'm really sorry :-(

My respects,

When you start a new thread, the first line asks you for the Thread Type in a options group. It defaults to question. Instead you can set your thread as Helpful Tip, News or Review:
This is located right above the subject you are asked to enter.

Bye, Olaf.

No need to apologise, Vilhelm-Ion. It is commendable of you to share your tips with us in this way.

As you have found, the "Helpful Tip" setting is useful for this type of post, especially if you wish other forum members to comment on it. For a more permanent contribution, consider writing an "FAQ". However, to do that, you will need to do more than simply post your code. Ideally, you should add some background information, such as what your code aims to achieve, what other solutions are available, and what the drawbacks are, if any, of your solution.

Also, when posting code (either in the forum or the FAQ section), could you please format it with [ignore]

 ...

[/ignore] tags. That way, it will be much easier to read. If you glance at many of the threads here, you will see what I mean.

Mike
