i just want to read info. *.ini file.

if i have a code
wsprintf(szName,"f:\\amginl\\amginl%s.bmp",csc);
DBChart1->SaveToBitmapFile(szName);
.
but now i want to write the path "f:\\amginl\\"in test.ini file.
and auto load the test.ini file to do
like a first code.how will i do ?
i think the code mabe is:

wsprintf(szName,"%samginl%s.bmp",aaa,csc);
DBChart1->SaveToBitmapFile(szName);

Like this:
GetPrivateProfileString("Your Section in INI file","Bitmap file" , "", szBuffer, MAX_PATH, test.ini);

After it szBuffer contains value for a key "Bitmap file" under section "Your section in INI file". You might want to check registry functions documentation (e.g. in MSDN)

Really proskig is right... That's the easier way to read an INI file...

100 pts. to proskig :-)

But you ask for fopen, isn't it?

i just try to writed som code to go.
my source code is:
//---------------------------------------------------------------------------
#include <vcl.h>
#pragma hdrstop
#include <stdio.h>
#include "Unit1.h"
FILE *file1;
FILE *file2;
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;
//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------

void __fastcall TForm1::FormCreate(TObject *Sender)
{

while(!Query1->Eof)
{

file1 = fopen("c:\\amginl.ini","r");
file2 = fopen("c:\\amgins.ini","r");
String aaa,bbb ;
fscanf(file1,"%s",aaa);
fscanf(file2,"%s",bbb);
char szName[255];
// get data from first table
// and save data into csc
String csc = Query1->FindField("STKCODE")->AsString;
String mkt = Query1->FindField("MKT")->AsString;
// into csc to second table and get data

if(mkt == "TSE"){
Query2->Close();

Query2->SQL->Clear();
Query2->SQL->Add("select stkcode,syear*100+smon,sb_vol,lb_vol,cp");
Query2->SQL->Add("from ap.amgin");
Query2->SQL->Add("where STKCODE =:sss");
Query2->ParamByName("sss")->AsString= csc;
Query2->Active=TRUE;

// use the data of second table to draw the line chart
Series1->DataSource=Query2;
Series1->ParentChart=DBChart1;
Series1->XLabelsSource="syear*100+smon";
Series1->YValues->ValueSource= "lb_vol";
Series2->DataSource=Query2;
Series2->ParentChart=DBChart2;
Series2->XLabelsSource="syear*100+smon";
Series2->YValues->ValueSource= "cp";
wsprintf(szName,"%s\\amginl%s.bmp",aaa,csc);
DBChart1->SaveToBitmapFile(szName);
Series3->DataSource=Query2;
Series3->ParentChart=DBChart2;
Series3->XLabelsSource="syear*100+smon";
Series3->YValues->ValueSource= "sb_vol";
Series4->DataSource=Query2;
Series4->ParentChart=DBChart1;
Series4->XLabelsSource="syear*100+smon";
Series4->YValues->ValueSource= "cp";
wsprintf(szName,"%s\\agmgins%s.bmp",bbb,csc);
DBChart2->SaveToBitmapFile(szName);
Query1->Next();
}
but i get some error message.
the message is:
