combobox max listcount

What is the max number of items that can be supported by the standard combobox?
I thought the max number of item that can be loaded in a combobox is 32736.
Am I wrong?

I am loading the list from a csv file that has more than 193243 items,
removing duplicates at the same time, it only reads up to line 192851.
It does not load all items, the list count is only 115.

As a guess you're hitting some memory limit where your list of items has exhausted the memory available to the control.

I have a hard time imagining why you'd want that many items in a combo box dropdown. It doesn't seem like a very usable way to use the control.

How then do I increase the memory limit for the control?
In the end I need about 150 items in the combobox.
The client I am developing this program requested a format where they can choose or type
in a choice from a list. To minimise errors by users i want to use a combobox for this.
If there is a better way please help.

First, I was offering a guess. I don't know how or if you need to mess with the control's memory.

Try using a grid control for the list, maybe?
