Hello all

I have an application that needs to read an ini file.

It needs to compare a number (a count) from an SQL statement to a number stored in the ini file. The number in the ini file will be stored next to an identifier such as  'client=3' and if possible i want to set how many places along the string the number will be in the ini file eg 'client=12*3*456' so the number i want for comparrison is still number 3

any help appreciated

OK

If i have an ini file that contains the line client=3, how do i read that in my delphi app and as a secondary question can i hide that number(the 3) in a string and count the places to find it as a sort of encryption

Cheers

uses TiniFiles;

Function GetMyINI_Data(IniFname,SectionName,KeyName: String): Integer;
var
ThisINI:    TIniFile;
s1:           String;
begin
result:=-1;
ThisINI:=TiniFile.Create(IniFname);

try
if s1<>'-1'  then
begin
result:=StrToIntDef(s1,-2);

// decode "whatever" you did to encode the number before you saved it in the INI file

end;

finally
ThisINI.free;

end;

end;

// decode "whatever" you did to encode the number before you saved it in the INI file
// i.e.
result:=(result div 12) div 456;

I really would not bother with something like this, I would just mathematically alter the number according to -some- formula

Some.INI
[Some.Section]
Client=16416

// 16416/12/456=3

Or to decode the hidden number from string you can use
s := '12*3*456';
s := Copy(s, pos('*', s)+1, length(s));
s := copy(s, 1, pos('*', s)-1);
