SendMessage doesn't seem to handle embedded tabs in a string

[SBendBuckeye]

Hello all,

I have a form which does a lot of listbox filling based on arrays. To try and speed it up, I am using the SendMessage API to fill the various listboxes instead of using the AddItem method (eg lstbox.AddItem).

Everything is working fine except for one listbox which sometimes gets filled with a string that contains an embedded Tab or NewLine character. When that happens SendMessage fails. Is there anything I can do to change this or am I missing something obvious here? Thanks!

Have a great day!

What do you mean? What happens exactly? Any error message?

It returns zero and the listitem is not added. There is no error message that I am aware of. If I run the exact code with a string that does not contain an embedded tab it runs properly. Thanks!
