[RESOLVED] Simple MDI problem

Hi all,

I'm trying to link my MDI child to the parent.
Although, there's no error when i run the program, but when i click the child form, there's no respond. I suspect the program cant read my child form or the name isn't correctly label.

May someone pls solve my query. Thanks.

Below is the link to my program.

could you post the code where you r loading the child form.... I dont have option to open the attachments.

Hi MACKY,

I found a small mistakes in your code.

In the mnuCarDetaila menu click event you have not written any code
that's why no action taken when you click menu 'Group A '. I think you have change the menu name after you had write code. Becoz I found the code for loading form in 'CarDetaila' menu click event, which is not exist in you menu items. Please check the menu names and code for menu click event.

Also be sure that the forms you are loading on menu click must be added in the project.

Under the Main form,

VB Code:

Private Sub CarDetaila_Click()
Unload CarDetailb
Unload CarDetailc
Unload SearchCustID
Unload SearchCar
Unload SearchInvoice
Unload Customer
Unload rent
Unload returned
 
Load CarDetaila
CarDetaila.Show
End Sub

There is no compile error in my form but when i click on cardetaila, there's no reaction.

Hi CHAMPGARY,

Thanks for the reply.
Can u explain furthur wat type of code do i need to write.

do you want to unload all the other forms in that event....no harm...but think twice....

after the load CarDetaila statement just give msgbox "Form Loaded" and then after CarDetaila.Show give again "Form Showed".

and see whether you are getting these msg boxes....

I'm sorry... I dint notice the mistake in your code...
just move the CarDetaila_Click event's code to mnuCarDetaila_Click event

hi ganeshmoorthy,

Is this what u mean?
Well, there still no differences from the earlier one.

VB Code:

Private Sub CarDetaila_Click()
Unload CarDetailb
Unload CarDetailc
Unload SearchCustID
Unload SearchCar
Unload SearchInvoice
Unload Customer
Unload rent
Unload returned
 
Load CarDetaila
If CarDetaila = True Then
MsgBox ("Form loaded")
End If
CarDetaila.Show
If CarDetaila = True Then
MsgBox ("Form shown")
End Sub

Ok .. thks ganeshmoorthy and CHAMPGARY. I think i got it.

But initally i change both names to cardetaila, it prompt me an error member or data methods not found.
Pardon me, do i have to put a mnu in front of my form?

For that
copy your code from the CarDetaila_Click() and paste it into
mnuCarDetaila_Click()
I have made changes in main form and attached with this.
Have a look.

Don't unload each form in menu click event. You unload all the forms in 'Exit' menu click event. That is ideal. If you really want to do so use
for loop for that.

Thanks CHAMPGARY.
For sharing your vast knowledge.

It is not mandatory to put mnu with the menu name, but is suggested and this is what called as naming conventions. on seeing the sub itself you can determine that this is menu event.

This is true, but it should ALWAYS happen, just like all strings should start with str, integers with int, etc.
