Hello,

I am using Delphi 2010 and facing some problem to open multiple window for example , when I run the program then i see the main window with some navigation buttons which are linked to another window , but the problem is: I cannot open multiple window by minimizing one after another, I always need to close the currently opened window in order to open the other one, I have tried to change the value from FormStyle property, but i am not successful,could you please give me some suggestion to solve this problem.

I would be thankful for your reply

How you show the windows ? Show or ShowModal ?

Moin..
Thanks for your reply

I use the ShowModal

That`s it...

Zitat:

Use ShowModal to show a form as a modal form. A modal form is one where the application can't continue to run until the form is closed.

use Show.

Thanks for your reply,i am going to try it out
actually i am new to Delphi, therefore i have another question, i have read some tutorial to understand the difference between procedure and function, but still now i am not so clear. for example ,i have seen that, the Show is a procedure whereas ShowMdal is a function, It would be so kind of you, if you tell me the difference between them, Thanks in advance.

Hy,

- a function gives you a result value, if the work is done,
- a procedure doesn't give you anything back (similar to the "void" in C++).

You can do something with the result of the funtion, for instance ShowModal returns the "ModalResult". With the ModalResult you can see in which way the modal form was closed, may be by pressing the OK-Button (mrOK) or the Cancel-Button (mrCancel) (see help).
This values you can set in the Object Inspector for the Buttons of your modal form.

Hi,
I have try it out with Show instead of ShowModal, now i can open multiple window as i wanted but the problem is , when i click on one button it opens two windows together and i also cannot close the window properly (i mean when i click to close ,it does not close , then i need to force to close the window)

do you have any suggestion please ?

You should give us a little bit more information (source code, form properties).

It seems that you are building a MDI application and TForm.FormStyle is set to fsMDIChild .
The behaviour (minimize on close) is as designed and you should use the TForm.OnClose Event.

But this is just a guess without any code or more detailed information from you

Thanks for your response , the FormStyle property is set to : fsNormal ,
and i have used the following events
FormCreate,
FormShow,
SormActive and
FormClose.

Sorry, but you show us so much code, so it will take some time to get into ...

Why do you think we have magic eyes to look at your screen or your harddisc or even inside your brain?
Be sure, we can't, and so we can't answer your question.

Think about how we can get a clue what you are doing and why it is not working as expected.
