txt can't be updated from TStringList.SaveToFile

[nicolas_lazarus]

Hi all,

I found a strange behavior trying to save in a txt files twice.
The first one works fine, but when I try to save again at the same txt file, the file can't be updated.

More over, I tried deleting the txt file but then the application cannot creates the file again.




piece of  code

Code: [Select]

outputProcess := TStringList.Create;
memStream:=TMemoryStream.Create;
P := TProcess.Create(nil);
.
.
.
p.Output.Read((memStream.Memory+BytesRead)^,READ_BYTES);
.
.
.

outputProcess.LoadFromStream(memStream);
outputProcess.SaveToFile(pathLogs+PathDelim+'xxxx.txt');
.
.
finally
P.Free;
outputProcess.Free;
memStream.Free;


Can someone see what is wrong ?

Thanks in advance!

I don't understand your code snippet. Probably, you have a sharing violation. Close the file by freeing TStringList and read from/write to the file after that. If you want to share information over one file look for "memory mapped file" if you intend to use Windows.

Hi all,


I found the problem. It is not related to TStringList.SaveToFile();

the problem was started  after excecute SetCurrentDir(pathApplication).

Solved.

Thanks anyway !
