Count number of physical lines in the text control

[OneEyeMan]

Hi, ALL,
In the text control there are 2 types of line: physical and logical.

Physical lines are divided by "\n\r" characters ("\n" on *nix), logical lines are used when the control is narrower than the text typed and there is a so-called soft "\n\r" character inserted by the control in order for not to display the horizontal scrollbar.

It looks like EM_GETLINECOUNT will return the number of logical lines, according to this. Is there anything that will return me a number of physical lines? Or I will have to manually go through the text buffer and count number of "\n\r" characters?

Thank you.

Does MFC offer any methods that help? Even if you aren't using MFC you can look at its source code for implementation.

1. Are you using a multi-line edit control?
2. How did you check that EM_GETLINECOUNT will return the number of logical lines?

Hi, VictorN,
Sorry for the late reply...

1. Are you using a multi-line edit control?

Yes. It doesn't make sense otherwise.

2. How did you check that EM_GETLINECOUNT will return the number of logical lines?

MSDN says so. And I tested.
It counts number of wrapped lines ("logical"), not the physical ones.

Thank you.

Well, i can understand (or just guess) why. To have a way to exactly know/calculate the position (in the control) of any character in the text depending on the "word wrap" option.

Why do you need to know the number of "physical lines"?

Why not just get the text and count the new lines?
