I'm trying to dynamically add a picturebox control to a form.

I'm following some coding I see in the form designer generated code:
....and so far....nothing. Any help is appreciated.
Dim myPicture As New PictureBox()

With myPicture

myPicture = New System.Windows.Forms.PictureBox()

..Visible = True

..Name = "NewPicture"

..Size = New System.Drawing.Size(64, 48)

'myPicture.Location.X = new System.drawing

..TabStop = False

..Location = New System.Drawing.Point(700, 300)

..Image.FromFile("c:\temp\holiday1.jpg")

..Show()

End With

[Crirus]

try this :
myForm.Controls.Add(myPicture)

Thanks for the hint. It didn't seem to work.

I'm looking around msdn.micrsoft.com and www.devx.com. Don't suppose you'd
know of anywhere else that you'd recommend for source code? Thanks again.

As a hint: Try google with "add controls to forms at run-time NET VB", if
still cant make it work, you may find other exemples

Hi Andy,
What is the size of your form

.Location = New System.Drawing.Point(700, 300)

Can it be that you paint it beside your form?

And you need in my opinion that Add that Crirus stated.

Cor

[Fergus Cooney]

Hi Andy,

You're right to use the code that the Form Designer creates but you have
to do it carefully (like Crirus's Controls.Add) - and know which bits to do
differently - like Image.

The Designer uses embedded resources which is not what you want. You
spotted that so you used

myPicture.Image.FromFile("c:\temp\holiday1.jpg")

Unfortunately this loads an image and then throws it away because it's not
being assigned to anything. The use of myPicture doesn't mean that it updates
myPicture!

The bit that you're missing is <setting> the Image.

myPicture.Image = Image.FromFile ("c:\temp\holiday1.jpg")

Regards,
Fergus

[William Armstrong]

Image.FromFile is a shared function which will return a new Image based on
the file. Being shared, it doesn't have an Image instance to load the file
into, so it won't change the Image who's reference you used to call the
function. Your code isn't assigning the returned image to the Image
property of your PictureBox.

Try replacing this line:
.Image.FromFile("c:\temp\holiday1.jpg")

With this line:
.Image = Image.FromFile("c:\temp\holiday1.jpg")

I think that your code to create and display the PictureBox is working just
fine, it just doesn't have an image to display. You do need to add the
picturebox to the form's control collection though (as mentioned in another
post).

[Crirus]

Maybe you will consider the ideea of direct paint the image on the form
without this struggle of adding picture box only for display

Something like this:

In form's Paint event

dim myImg as new Image.fromFile(...)
e.Graphics.drawImage(myImg,....)

Hi Fergus,

Good morning

Where did you been, did you sleep a night, very good.

Or was it football with all those London clubs?

:-))

Cor

[Cor]

Hi Fergus,

With that what Crirus now tells I was strugling yesterday.

In your example for me you use that
e.graphics.draw(master,rectangle,rectangle,size)

It was drawing direct on the screen in the place of the second picture box.
You did use the rectangle of that picture box. I found it now, but did cost
some thinking before I saw it was not placed in that picturebox.

(All is ready now I start to get it smaller and saving.
I start just with seeing if the thumbnail will work for me, and if that does
not work for me. I go search and will ask Herfried, Nick, Crirus and you
again, how I can delete some information from the pixel information. (Not
just removing pixels, that gives not nice pictures). But bringing by
instance colours back from 16Kbits to 64bits or what is more not direct
needed information for internet.

Cor

[Fergus Cooney]

Good morning Cor,

I promised Scorpion that I'd write him a Registry Searcher so I had to
keep the modem unplugged and give myself time for it. (otherwsie - too much
temptation to answer 'just one more question'). And I still have another
couple oif things that need to be done for people. I heaped my plate high -
now I have to eat it!

Football? What's that?? ;-))

Regards

[Crirus]

Before unplugg again the modem, will you look at my issue about mouse
cursor.. :D

please!

Hi Cor,

Sounds good...I look forward to seeing it.

You'll be studying these I reckon.

Hi Fergus,

To forfill this I try to do everything in English.

Sounds good...I look forward to seeing it.

Did you know that this is an advantage normaly from non native English
language programmers on native English language programmers.

We use our own language for variables and english for keywords and defined
objects etc. And because a lot of non native English speakers send in code
parts, I'v seen here we normaly do that all.

By doing this we have never a problem to get mixed up. But now I did take
the chalenge to do it in English, so I can show you the results and I am
developing it still as a stand alone program.

[Fergus Cooney]

Hi Cor,

|| We use our own language for variables and english for
|| keywords and defined objects etc
|| By doing this we have never a problem to get mixed up.

It's a nice advantage - much clearer separation of App from System. Also,
you get your own choice. Many's the time I'd like to use a word that has
already been taken.

But for sticking to English - thanks! ;-)

Fergus

[Andy Chan]

Hi Fergus,

Thanks for the input.

Wow. I've been doing VB 6 for sometime now. I've been behind the times and
finally sitting down to do some .NET coding. Boy, what a difference. It's
like I have to start all over again.

SUCCESS!!!

Thanks to everyone who contributed! Hope to return the favor someday.....but
umm.....I think I've got a bit of a learning curve before I do so.

It seemed to come down to 2 things I was doing wrong:

1. mypicture.Image = Image.FromFile("c:\temp\holiday1.jpg") was definitely
it.

and

2. I was adding the the control with me.controls.add after I was trying to
set the picture. Once I moved this before the picture creation, no problem.

Addendum:

How would you add more than 1 image?

I've tried to add a second graphic, but it only shows the first one. I know
the coding is correct, as I can comment out the coding for the 1st picture,
and the 2nd photo shows up.

Hi Andy,

The second one should replace the first. Perhaps you should show us the latest version of the code.
