Hi i started working on app with mysql and data module, on computer
where i programing run perfect so copy the app and dll library , but
when run on other computer first is tried to load the app from the
folder where i programing or development the app , and  i see data
module when is create take all datas as was configured , so i move to
not be first form on app to avoid that problem but still send me error
can load library... now shoe me folder where the app is running is
what i wanna....

two thinks...

1.- How i can change datas for datamodule when is the first to create
on app.... to initialize all values

2.- How i can install the right dll because if is running 32 or 64
bits, as mentioned i put same dll i using on develop environment but
on runing machine doesn't work..

 Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TDM.DataModuleCreate(Sender: TObject);begin   INI :=
TINIFile.Create('Server.ini');   MySQLCTrav.ClientLibrary:='';//  if
t4a_Is64BitWindows then begin//  
 MySQLCTrav.ClientLibrary:=GetCurrentDir+'\libmysql32.dll';//  end
 else  begin//  
 MySQLCTrav.ClientLibrary:=GetCurrentDir+'\libmysql64.dll';//  end; 
if( FileExists(GetCurrentDir+'\Server.ini')) then begin   
 MySQLCTrav.HostName := INI.ReadString('Server','HostIp','');   
 MySQLCTrav.UserName := INI.ReadString('Server','User','');   
 MySQLCTrav.Password := INI.ReadString('Server','Password','');   
 MySQLCTrav.DatabaseName :=
INI.ReadString('Server','DatabaseName','');     MySQLCTrav.Port :=
INI.ReadInteger('Server','Port',3306); end else begin   
MySQLCTrav.DatabaseName:='Traveler';   
MySQLCTrav.HostName:='localhost';    MySQLCTrav.UserName:='kkkk';   
MySQLCTrav.Password:='9999';    MySQLCTrav.Port:=3306;   
Ini.WriteString('Server','HostIp',MySQLCTrav.HostName);   
Ini.WriteString('Server','User',MySQLCTrav.UserName);   
Ini.WriteString('Server','Databasename',MySQLCTrav.DatabaseName);   
Ini.WriteString('Server','password',MySQLCTrav.Password);    Ini.Write
Integer('Server','Port',MySQLCTrav.Port); end; MySQLCTrav.ClientLibrar
y:=GetCurrentDir+'\libmysql.dll'; MySQLCTrav.Connected:=true;end;

Straws and grasping here.

You mentioned one single dll. Is that all that is distributed ? Are
all the dependencies that the mysql library depend on present on the
machine that generates the error ?

See dependency walker from M$

Thanks Tron well on server must be all dependency  but on client side
too ...
