Hi,

This is regarding character substitution in a string variable under b4A.


Doubt 1:

I want to perform the following steps on a string.

This String has, among other characters, many occurrences of CHR(171), CHR(191) and CHR(172)

1) Replace all occurrences of CHR(171) with "" i.e. Double QUotes

2) Replace all occurrences of CHR(191) [i.e. inverted Question mark symbol]
with CHR(172)

3) Replace all occurrences of CHR(172) with ' (i.e. single quote)


And the operations have to be performed in the above order.

Doubt 2:

How to assign the 'transformed string' as per above sequence to a label control in b4A ?

I mean, do I have to put any escape sequences for all the single quotes and the double quotes that will result from the above sequence of transformations ? Requesting for showing by an example.

Thanks..

You can try:

B4X: 
StrInfo    = StrInfo.Replace(chr(171), chr(34))    ' Double Quotes
StrInfo    = StrInfo.Replace(chr(191), chr(172))
StrInfo    = StrInfo.Replace(chr(172), chr(39))    ' Single Quote

B4X: 
    Dim StrInfo As String = $"${Chr(171)}${Chr(191)}${Chr(172)}"$
    Label1.Text = StrInfo.Replace(Chr(171),Chr(34)).Replace(Chr(191),Chr(172)).Replace(Chr(172),Chr(39))
