How do I specify what I want in ShowMessage? 2

[delphiman]

I need to have (something like) the following which is obviously wrong. What should the code be?


ShowMessage ('Account' + dmStdAcc.qryGLGLNo.value + 'already exists. Delete it.');

Anyone?

You need a message dialog - eg:

  MyResult := MessageDlg('Account' + 
    dmStdAcc.qryGLGLNo.value + 'already exists. Delete it?',
    mtInformation,[mbYes, mbNo],0);

[tt]MyResult[/tt] returns the value of the button you chose - so you can take the appropriate action. There a set of buttons available for use, as well as dialog types - [tt]mtInformation[/tt] refers to the type of dialog - basically changes the icon in the dialog.

Check out the [tt]MessageDlg[/tt] help for more information.

There are also a bunch of third party extensions to this, that extend the control - including a few on the Delphi 6/7 distribution disks

Good luck!

Chris ;-)

or like this

if MessageDlg('Account' + 
    dmStdAcc.qryGLGLNo.value + 'already exists. Delete it?',
    mtInformation,[mbYes, mbNo],0)=mrYes then do somthing;

Sorry guys! You have both got it wrong!
The message is making a STATEMENT. It is not asking a question.

My problem is that the following bit doesn't work

+ dmStdAcc.qryGLGLNo.value +

Any more suggestions?

I assume that this '.value' is a string?

You can use the original ShowMessage or MessageDlg, but ensure dmStdAcc.qryGLGLNo.value is a string. So if it's a float then use:

+ FloatToStr(dmStdAcc.qryGLGLNo.value) +

or if it's an integer use:

+ IntToStr(dmStdAcc.qryGLGLNo.value) +

There are other formatting routines depending on your needs but these are the very basic ones for real and integer values.

What is dmStdAcc?
...And what is qryGLGLNo?

I assume qryGLGLNo is some kind of query field.

Try use dmStdAcc.qryGLGLNo.AsString instead.

You might want to consider using ShowMessageFmt as this combines the ShowMessage and Format functions.

  ShowMessageFmt ( 'Account %s already exists. Delete it.', [dmStdAcc.qryGLGLNo.AsString] );

Like Nordlund, I'm assuming that qryGLGLNo is a TField.
