ShellExecute from Delphi5 application
Dear Expert,
I need to execute following command line from delphi5 application:

C:\Windows\system32>aws s3 cp "c:\test.csv" s3://testbucket/

I am coding as below:

ShellExecute(0, nil, 'cmd.exe', 'aws s3 cp "c:\test2.csv" s3://testbucket/', nil, SW_HIDE);

I tried the below code too:

ShellExecute(handle,'open',PChar('c:\Windows\syste m32\cmd.exe'), PChar('aws s3 cp "c:\test2.csv" s3://myerofirstbucket/'), '', SW_SHOWNORMAL);

But the file is not being copied in the required destination. However, if I run the above command from CMD, its coping successfully. Kindly suggest.

Thanks in advance

Instead of cmd.exe you should execute aws
And ShellExecute has a result that can be an error code.
Something like:

  executeResult: integer;
  executeResult := ShellExecute(....);
  if (executeResult >32)
    ShowMessage(SysErrorMessage(GetLastError)); // or perhaps directly on executeResult

Dear Norrit,

I executed as below; I am not sure if this is the way to be done. But the file is not being copied.

ExecuteResult := ShellExecute(0, 'open',pchar('aws.exe'), pchar('aws s3 cp "c:\test2.csv" s3://myerofirstbucket/'), nil, SW_SHOWNORMAL);

if (executeResult >32) then

The message shows "Operation completed successfully"

Thanks and regards,

What is the value of ExecuteResult ?

And it's pointless to duplicate aws. First aws is the program to execute, the second is part of the parameter list, so therefor it shouldn't be there.

ExecuteResult := ShellExecute(0, 'open',pchar('aws.exe'), pchar('s3 cp "c:\test2.csv" s3://myerofirstbucket/'), nil, SW_SHOWNORMAL);
