stringreplace character in all string

[William23668 8]

 

I have string like this

84@fgl#000^2#0#0 94j@f#0

And I tried to replace all '#0' with '0' like this

 

result := stringreplace(OriginalStr, '#0', '0',[rfReplaceAll, rfIgnoreCase]);

But this did not replace all the '#0' , how I should use this ?

Can you show what the output of your code is. It should be easy to produce a minimal complete program, a console app, that demonstrates the behaviour that you are struggling with.

I test it with this line

 

fstr := 'MZ'#$0090#0#3#0#0#0#4#0#0#0'ÿÿ'#0#0'¸'#0#0#0#0#0#0#0'';
fstr := stringreplace(fstr,'#0','0',[rfReplaceAll, rfIgnoreCase]);

output is (copied from the watch window)

 

'MZ'#$0090#0#3#0#0#0#4#0#0#0'ÿÿ'#0#0'¸'#0#0#0#0#0#0#0

Should be #0 rather than '#0'. Your code is replacing the text '#0' which doesn't appear in the string.

love you. many thanks

Big lesson here is always to show a proper minimal but complete reproduction. It wasn't clear what the problem was from the first post which was descriptive. Code doesn't lie.

Also, this isn't how to display binary in a hex editor.

No it was just to practice.

Try using RxStrUtils in unrxlib

function ReplaceStr(const S, Srch, Replace: string): string;

Why is that better than StringReplace? How does it relate to the problem in this thread?

I'm sure your function would give the same result. Did you read the earlier posts? They explain what is going on.
