Why "ShowMessage" fail the compile in Delphi?

[charvo]

Hi, I am using ShowMessage() in delphi to work as Alert() in MT4.

but my code cannot go thru the compiling in Delphi 7.

the error is: Undeclared Identifier 'ShowMessage'

how come does this happen? I thought 'ShowMessage' is a Delphi function, isn't it?

Code: Select all

ShowMessage('NIMA FAILED to enter a REAL ');

the code is very simple.

Did you USES DIALOGS or not ?

Yes. Very Simple. Just google 'Delphi ShowMessage'

my google's 1st result is from DelphiBasics which didn't show 'Use Dialogs' in its example, my bad----should look more

Remember:
- On the Upper Top Right give the info of Unit should uses eg. "Dialogs Units"
- Click on the below show "Show full unit code" to see the examples, Look into the uses section.

If no sure, try the example and then compare with your FT code. That how you learn.
