Hello Dimitri

A question about DBImage component.
How would you do to clear picture showed in a DBImage ?

I've tried many codes :

myForm.DBImage1.Picture.Bitmap.Assign(nil);    or
myForm.DBImage1.Picture.Graphic:= Nil;              or
myForm. DBImage1.Picture.Graphic.Empty;

Each time, I get error message saying : 'Could not convert variant of type|Null] into type [Integer]
Obviously, a transtypage problem.

If I try this :

myForm.DBImage.Picture := nil;
Well, Okay, picture has flew away but the component DBImage also with it.

Thanks for your answer !

Hello Dimitri

By being inspired from your script :

Form1.TableGrid1.Cell[0, 0].Color:= clRed;
Form1.TableGrid1.Cell[0, 0].TextColor:= clGreen;

In a column titled, how could I get a different color by theme.
Example :

I have a column titled Gender (for books)
I would have all books Fantasy colored blue, all Thrillers red, all novels green, and so on.
By the way, how to have all the different row colored by theme ?

I don't guess what will be the script.
All I have tried give up error.

Thanks for you help

Hello Dimitri,

To develop MVB

2 new functions which could be good for our application :

- Using a Treeview (or a DBTreeview) : MVB would have a professionnal aspect. I used it with Delphi 7 but this one don't work under Windows 8 et I haven't the courage to write again this application under RAD XE3 (... whatever ...)

- Add 2 news properties at TableGrid to get differents colors for alterned rows. (cause event OnDrawCell is not actived in MVB). But I guess that MVB don't use native TableGrid from RAD XE3. It feels Bergsoft's component NextDBGrid, isn't it ?

Well, if not, too bad, and long life to MVB !

Hello

It seems that with TableGrid, method OnDrawColumnCell is not enabled.
(I tried to get something like TableGrid1.OnDrawColumnCell.Enabled := True
and I get an error message).

Should it be possible to allow this in next version of MVD ?
We could put color on alterned rows, get an alignment for title et son on ...

Thanks

Hello Dimitri

I'm making a test on my VDB about birds.

To reduce many forms I have, I'm testing 2 comboboxes populated
with 2 text files (orders and families ) through a script :

Affichage.ComboBox1.Items.LoadFromFile(Chemin + 'Ordres_Oiseaux.txt');
Affichage.ComboBox2.Items.LoadFromFile(Chemin + 'Familles_Oiseaux.txt');

That's works fine (the loadings).

But I would  Combobox.Text be filled by the user's choice from file loaded (i.e Orders).
I'm not very good with Items.Index.
Have you any ideas about the way to succeed ?
And how to save those selection through a Save button (directly or with a script) ?

Another error message : Compilation tells me "no such columns" .
So I'v declared in my main table called Oiseaux those 2 fields : Order and Family.
It occurs when I want modify a record already saved

Thanks for your help

Best regards

Hello Dimitri

If I would place a nice button (with icone and picture) to remplace the gray basic button  of MVD, what would be the real syntax to place behind.

For example, in MVB, after selecting the record to delete, the button DELETE --> (Action) DELETE RECORD -> SELECT THE GRID -> , what would be the delphi syntax to perform the same result ?

Thanks for answer

Great Thanks
