Textbox scrolling

When I use textbox.appendtext(buff), buff is successfully appended to the textbox and the textbox automatically scrolls.

However, there seems to be a limit... the scrolling stops (as does the data being appended) after a certain amount of data is appended.

I have the maxlength set to 0 and have also tried setting it to 1,000,000.

I have resorted to:

textbox.text+=buff
textbox.selectionstart=txtbox..text.length
textbox.scrolltocaret()

Unfortunately, that scrolls the text all the way to the beginning and then back to the end everytime which causes undesirable flashing.

Does anyone know why the appendtext method is limited

        FileOpen(1, "c:\mlx\eventlogs\test.mlg", OpenMode.Binary, OpenAccess.Read, OpenShare.Shared)

        txtMainOutput.AppendText(InputString(1, FileLen("c:\mlx\eventlogs\test.mlg")))

        FileClose(1)

i set the txtMainOutput.maxlength to 0 but the appendtext method seems to only append 32767 characters. The file is 6 megabytes.

Any help would be appreciated. THanks.!

I have only encountered a limit problem when using the appendtext method. If I do output.text+=buff, everything works fine - no limit issue using a standard textbox.

The example was reading a file, if you simply coded a for loop to .appendtext a 1000 byte buffer 40 times, the text would only contain the first 32767 bytes.

I am using VS 2003.

Everyone: Thanks for your help on this. I started really searching (google) this topic and found a number of posts relating to the 32767 limit of the appendtext method. Apparently this is pretty much a bug...

I'll research the rich textbox control.

Thanks again
