stringgrid从文本读入的问题

Save/Load a TStringGrid to/from a file?

// Save a TStringGrid to a file

procedure SaveStringGrid(StringGrid: TStringGrid; const FileName: TFileName);

var

f: TextFile;

i, k: Integer;

begin

AssignFile(f, FileName);

Rewrite(f);

with StringGrid do

begin

// Write number of Columns/Rows

Writeln(f, ColCount);

Writeln(f, RowCount);

// loop through cells

for i := 0 to ColCount - 1 do

for k := 0 to RowCount - 1 do

Writeln(F, Cells[i, k]);

end;

CloseFile(F);

end;

// Load a TStringGrid from a file

procedure LoadStringGrid(StringGrid: TStringGrid; const FileName: TFileName);

var

f: TextFile;

iTmp, i, k: Integer;

strTemp: String;

begin

AssignFile(f, FileName);

Reset(f);

with StringGrid do

begin

// Get number of columns

Readln(f, iTmp);

ColCount := iTmp;

// Get number of rows

Readln(f, iTmp);

RowCount := iTmp;

// loop through cells & fill in values

for i := 0 to ColCount - 1 do

for k := 0 to RowCount - 1 do

begin

Readln(f, strTemp);

Cells[i, k] := strTemp;

end;

end;

CloseFile(f);

end;

　

// Save StringGrid1 to 'c:.txt':

procedure TForm1.Button1Click(Sender: TObject);

begin

SaveStringGrid(StringGrid1, 'c:.txt');

end;

// Load StringGrid1 from 'c:.txt':

procedure TForm1.Button2Click(Sender: TObject);

begin

LoadStringGrid(StringGrid1, 'c:.txt');

end;

*******************************************

打开一个已有的文本文件,并将内容放到stringgrid中,

文本行与stringgrid行一致;

在文本中遇到空格则放入下一cells.

　

搞定！注意，我只写了一个空格间隔的，你自己修改一下splitstring可以用多个空格分隔！

procedure TForm1.Button1Click(Sender: TObject);

var

aa,bb:tstringlist;

i:integer;

begin

aa:=tstringlist.Create;

bb:=tstringlist.Create;

aa.LoadFromFile('c:.txt');

for i:=0 to aa.Count-1 do

begin

bb:=SplitString(aa.Strings[i],' ');

stringgrid1.Rows[i]:=bb;

end;

aa.Free;

bb.Free;

end;

其中splitstring为：

function SplitString(const source,ch:string):tstringlist;

var

temp:string;

i:integer;

begin

result:=tstringlist.Create;

temp:=source;

i:=pos(ch,source);

while i<>0 do

begin

result.Add(copy(temp,0,i-1));

delete(temp,1,i);

i:=pos(ch,temp);

end;

result.Add(temp);

end;
