VB Forum / General 2 / February 2005richttextbox.find UNICODE text failure
Any way to make the .find method of the richtextbox work with unicode text? I have everything else working on a unicode project. I can display unicode text in the proper language, but the .find method always returns -1. I have the charset and font set properly. Any ideas will be appreciated. This is in VB6 with SP6 . The box is listed as sp4 richtx32.ocx. It appears to find ansi text but even that does not seem to return the proper position.

It will find the position but assigning this to selstart of the box does not work reliably. > > > Any way to make the .find method of the richtextbox work with > unicode [quoted text clipped - 16 lines] > It will find the position but assigning this to selstart of the box > does not work reliably. Have you also tried the UpTo-method? InStr returns a value from 1:length, whereas the SelStart property runs from 0:length-1. Could it be this difference you're seeing Max?

Could it be this difference you're seeing Max? SelStart runs from 0 to Length (not Length - 1). SelStart is the position along side of characters (not a count of the characters) and, as such, can be in front of the first character, behind the last character, or any where in-between.

But you'd surely figured out that. I dont have enough information: Please tell me more about the mistake. If there is one with the find-method I cannot imagine how it looks. Have you tried the find-method with all aviable parameters? ...Maybe you have chosen to search casesensitive and it does not work because of that. I found out you have to leave off the options at the end And you have to include the length of the rtb for the ending so it goes like this position = rtb.Find(Find.Text, rtb.SelStart, Len(rtb)) If you put any options on it or you leave off the 'end' value, it wont work properly. Just use text you want to find, the starting position and the ending position only. Another question. On internationalization with unicode and vb6. I have my system as English USA and when I test my program, I had to go to control panel, regional settings, install the language off the XP Cdrom, then I have to set under the advanced tab the desired language for nonunicode programs. Restart and the vb app properly displays the appropriate language chars. And it works great. I also have to set up a keyboard to copy text back and forth. All this works. The question is, on a localized XP installation say in Chinese Taiwan, Will the VB app display the proper characters? Or not? Or does someone have to set under the advanced tab some language setting? What if the XP system is a Chinese version of XP and the advanced tab is set for Chinese? What if the XP system is a chinese version of XP and the advanced tab is set for english? Any thoughts on this would be great. > I found out you have to leave off the options at the end > And you have to include the length of the rtb for the ending so it goes [quoted text clipped - 27 lines] > > Any thoughts on this would be great. I think as long as you're using unicode this should work always, because unicode is unicode in any language. Unicode saves every char as 16-bit-value -> It uses more memory. But therefor unicode is able to save the charset/language for each character inside, so that you can even use multible languages/charsets in one text. But all chinese people I know do not work with their languagesetting only, but also have installed the english keyboardlayout! rtb.find method wont work with russian cyrillac text, just returns -1 But It does work with english and chinese, but russian is out here is the rtf out of the rtb My question is, should it work??? ?rtb {\rtf1\ansi\deff0{\fonttbl{\f0\fnil\fcharset204 MS Sans Serif;}} \viewkind4\uc1\pard\lang1049\f0\fs20\'d4\'e8\'ed\'ec\'e0\'f0\'ea\'e5\'f2-\'c1\'e8\'e7\'ed\'e5\'f1^(TM) - \'e4\'e5\'eb\'ee\'e2\'ee\'e9 \'e6\'f3\'f0\'ed\'e0\'eb the twist in time \'ca\'f3\'f0\'f1 \'e4\'ed\'ff. \'ce\'f6\'e5\'ed\'ea\'e0 \'e4\'eb\'ff \'e3\'e5\'ed\'e5\'f0\'e0\'eb\'fc\'ed\'ee\'e3\'ee \'e4\'e8\'f0\'e5\'ea\'f2\'ee\'f0\'e0 \'cf\'e8\'f1\'fc\'ec\'e0 \'e8\'e7\'e4\'e0\'eb\'e5\'ea\'e0. \'d1\'f3\'e4\'fc\'e1\'e0 \'fd\'ec\'e8\'e3\'f0\'e0\'ed\'f2\'e0 - I "\'c2\'ea\'eb\'e0\'e4\'fb\'e2\'e0\'f2\'fc\'f1\'ff \'e2 \'fd\'eb\'e8\'f2\'f3" - \'ed\'e5 \'f2\'ee\'eb\'fc\'ea\'ee \'e4\'eb\'ff \'ef\'f0\'ee\'e4\'e0\'e6\'e8 \par } |
