Max. # of chars on a single line of a multiline textbox

[michael_hk]

Hi guys,

 

I have a resizable multiline textbox. How can I get the number of characters a single line can accommodate? I can only find textbox.Width...

 

Thanks.

The main problem you will have is if you are displaying text with a variable width font - the number of characters is dependant on which characters are entered.

You may get some mileage out of the MeasureString method...

Yes, the amount of chars will vary unless you use a font where the chars have a fixed width like courier new or lucida console, in which case you can use the Graphics.MeasureString() function to figure out how many chars you can fit.

Thanks for the info.

 

Finally I use "Courier New 9 pt" and estimate the # of chars by

 

nChar = textbox.Width / 10; // 10 pixel for a "Courier New 9 pt" letter

 

The result is not very accurate, but fine for me.

 

Thanks again for all your help.
