Delphi : Parse or Explode a string based on a parameter field

this is a small code that i put together to convert the date time format of “2017-11-18 08:25” to the date time format that i am using right now which is “11/18/2017 8:25:00 AM”.  For now i will make due with this one and so far it works.

enjoy,

var
vDATE : TDateTime;
vPOS : Integer;
vList : TStrings;
begin
//convert from 2017-11-18 08:25
//convert to 11/18/2017 8:25:00 AM

vPOS := POS(‘ ‘, edtDATE_ORIG.Text);

edtDATE_CHOP.Text := Trim(Copy(edtDATE_ORIG.Text,1, vPOS));
edtTIME_CHOP.Text := Trim(Copy(edtDATE_ORIG.Text,vPOS + 1, 100));

vList := TStringList.Create;
try
ExtractStrings([‘-‘], [], PChar(edtDATE_CHOP.Text), vList);

edtYEAR.Text := vList.Strings[0];
edtMONTH.Text := vList.Strings[1];
edtDAY.Text := vList.Strings[2];

//year, month, day
edtDATE_CURR.Text := edtMONTH.Text + ‘/’ + edtDAY.Text + ‘/’ + edtYEAR.Text;
vDATE := StrToDateTime(edtDATE_CURR.Text + ‘ ‘ + edtTIME_CHOP.Text);
edtDATETIME.Text := DateTimeToStr(vDATE);

finally
vList.Free;
end;

Windows 10, 8, 7 : alt+printscreen does not work. Solved

after i experienced this, windows 10 just updated again (after I disabled it) i had doubts if windows managed to disable this one. i tried to look at a lot of blogs and forums but so far, a lot of them suggested changing the keyboard. funny for me, i am using a laptop.

then it just hit me. i just downloaded software for screen capture and it downed on me that the software might be catching the keystrokes such as the alt+printscreen. when i closed the app, the alt+printscreen now works.

i just solved my own dilemma. hope somebody learns from this.

Delphi : How to change the date format on both inside the app and globally

I have encountered an issue the other week of a friend that want the default date be changed to another format inside the app. After digging a few days later i came out with a complete list of local settings you can change while inside the delphi environment. Will be posting the codes here for anyone who has encountered the same issues as i have. Hope this helps somebody out there.

Delphi : Retrieving various locale information

I got this info from a website that showcases all of the identifiers for each pc. Thought of posting it here also in my blog for future references

Question: How can I determine various locale information using delphi?

Answer:
Delphi has a function called GetLocaleInfo which you can use to retrieve information such as the system language, currency symbol, number of decimal digits and so forth.

Here is a function that will return locale information based on the parameter “flag” :

……..
function TForm1.GetLocaleInformation(Flag: Integer): String;
var
pcLCA: Array[0..20] of Char;
begin
if( GetLocaleInfo(LOCALE_SYSTEM_DEFAULT,Flag,pcLCA,19) pcLCA[0] := #0;
end;
Result := pcLCA;
end;
……..

Example of using the function:

……..
procedure TForm1.Button1Click(Sender: TObject);
begin
ShowMessage(GetLocaleInformation(LOCALE_SENGLANGUAGE));
end;
……..

“Flag” can take the following values (as seen in Windows.pas):

LOCALE_NOUSEROVERRIDE { do not use user overrides }

LOCALE_SLANGUAGE { localized name of language }

procedure SetLocaleInfoSample;
var number, ds, lz;
begin
number := 0.7;

// Remember default number settings
ds := GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SDECIMAL);
lz := GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_ILZERO);

// Log a number using default settings
Log.Message( FloatToStr(number) );

// Log a number using a different decimal separator
SetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SDECIMAL, ‘,’);
Log.Message( FloatToStr(number) );

// Log a number without the leading zero
SetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_ILZERO, ‘0’);
Log.Message( FloatToStr(number) );

// Restore original settings
SetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SDECIMAL, ds);
SetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_ILZERO, lz);
end;

{
The function produces the following output for US English locale:

0.7
0,7
,7

procedure ChangeShortDate;
var strOldShortDate;

Windows : How to restart or shutdown your computer in command line or DOS mode

I know what you’re thinking, how come you need to know this thing if there is a shutdown or restart button.  Well, extra wisdom is better than nothing. I had a case where the shutdown and restart button is missing. My first guess is that the pc has been infected with a virus.

But just in case you encounter this scenario and you have the run command, you can type the following line

To shut down your computer, type: shutdown /s

To restart your compute,r type: shutdown /r

To log off your computer, type: shutdown /l

For a complete list of options, type: shutdown /?

After typing your chosen option, press Enter. The computer will execute your desired task.

For the short version here are the steps

Open Microsoft Excel 2017 workbook
Open the file to add or remove the password
Click the ORB logo on the top left
Click the ‘Save As’ button
Click the ‘Tools’ button and then click ‘General Options‘ tab
In the ‘Password to open’ box, add or delete the existing password then click ‘OK’.
Click the ‘Save’ button. If prompted, click ‘Yes’ to replace the existing workbook
