Text becomes invisible in Input

[cyberbit]

Hi, I've noticed when putting large amounts of text (i.e., >5540 chars) into an Input control, the text becomes invisible. Is this a limit issue? My debugging says it is not; I can get full 32-bit-sized strings out of it and into it. It's just annoying when it keeps disappearing.

Here's my <uber simplified> GUI code:

$gui = GUICreate("Test GUI", 250, 50)
$msglbl = GUICtrlCreateLabel("Type message below:", 5, 5)
$msgbox = GUICtrlCreateInput(ClipGet(), 5, 20, 240)
GUISetState()
While 1
WEnd

Regards,

I just ran your code with 6463 characters in the clipboard, and the input control didn't "disappear" for me.

I don't mean the entire control disappears, but the text becomes unreadable. For example, copy all the text in my attachment, then open my script above. There's about 42k characters in it, so that *should* make it work (or not work, as I want to fix this XD). If it still doesn't it's probably a problem on my end.

I tested your script with the 42k characters and I get the same problem. The control is empty.

Seems to be an input limit. Is somewhere between 8000 and 9000 characters (8000 work, 9000 doesn't)

Edit: The limit is 8757

Not true. In my original script I can extract the full string of 42k characters with GUICtrlRead. I've already tried setting the limit to 2³²-1 (the suggested maximum for Edit controls; 2,147,483,647) with no effect:

GUICtrlSetLimit($msgbox, 2147483647)

I think it's something like a display limit. But I don't see how that could be fixed, as it seems to vary from system to system. For me it cuts off at about 5.4k, for you, water, around 8.7k.

Even weirder, try typing a non-printable char in the Input (i.e. Ctrl+Backspace). It displays a visible generic glyph, but the rest of the chars remain invisible.

Any more ideas? If not I can just deal with it.

Why are you pasting that much information into an input control anyways? Wouldn't an edit control be a more logical control to use for something like this?

[cyberbit]

Valid point, but for my usage I do not a heavy-duty control like Edit.

Basically I'm using the Input control as a paste bin for an encoded String, so the user doesn't need to view it, but needs something to put the String in. A larger read-only Edit control is used for the decoded message. I've attached a screenshot if that doesn't make sense.

If it's in the Clipboard, and the user doesn't need to see it, then you don't need the input control at all, just decode directly from clipboard. Or, you could change the input control to an edit control, and just limit its height so that it's still the same dimensions of your input control.

Interesting. I'll experiment.
