creating new Image object

i am building a word processor and want to be able add picture to the form. how could i add create imageboxes at runtime so that the user can add pictures as many times as they like. any help would be great as i'm completely baffled how to do this. sorry i dont have any code to post to show.

There two (and ony two) ways to add control at runtime:

- control array (easy and most commonly used)
- controls collection (also easy but creates some problems accessing new controls)

In any case to use control array add new image control in design and set its Index = 0. At runtime use the following logic:

VB Code:

Load Image1(Image1.Ubound + 1)
Image1(Image1.Ubound).Move 100, 100 'you must determine where you want it
Image1(Image1.Ubound).Picture = LoadPicture("full_path_goes_here")
Image1(Image1.Ubound).Visible = True

To utilize controls collection here is the logic:

VB Code:

Dim img As Image
 
Set img = Controls.Add("VB.Image", "imgTemp") 'you need to come up with unique sequence to name each new control
img.Picture = LoadPicture("full_path_goes_here")
img.Move ...
img.Visible = True

RhinoBull, with the control array code(which i can understand and easily use) does this load many pictures at once or only one and also can, if i put in a function say, run to add as many pictures as i want all individually. Thanks for the code already

You can do that in the loop - here is a general idea:

VB Code:

Option Explicit
 
Private Sub Command1_Click()
    'add 5 more pictureboxes
    AddMorePictures 5
End Sub
 
Public Sub AddMorePictures(iCount As Integer)
Dim i%
 
    For i = Picture1.UBound + 1 To iCount
        Load Picture1(i)
        With Picture1(i)
            .Picture LoadPicture("...")
            .Move '...
            .Visible = True
        End With
    Next i
 
End Sub

thanks i'll try that and get back to you. sorry about the delay in replying but i couldnt find the thread

In case you don't know you can subscribe to a thread.

Done. thanks for that piece of advice.

Not at all. :wave:

when i use the code above it says method or data member not found(i think) on this bit of code

VB Code:

picture1.Ubound

what could be causing this problem :confused:

***bump****

If you want to use Control Array then set Picture1.Index = 0 (zero) in the properties window.

i have adapted your code to use the imagebox. but when it runs i get error 13 type mismatch and it highlights the commented line in this code. Why?

VB Code:

Public Sub AddMorePictures(iCount As Integer)
CommonDialog1.ShowOpen
pictureload = CommonDialog1.FileName
    For i = Image4.UBound + 1 To iCount
        Load Image4(i)
       
        'Image1(i).Picture pictureload
        Image1(i).Move 12, 34, 56, 67
        Image1(i).Visible = True
    Next i
 
End Sub

:confused:
BTW the commented line isnt commented out in my app that is just to show where the error occures

Didn't you see this line in one of my previous posts:

Image1(Image1.Ubound).Picture = LoadPicture("full_path_goes_here")

So, what you need is to properly use LoadPicture() function:

VB Code:

Image1(i).Picture = LoadPicture("c:\temp\some_image.bmp")
'or
Image1(i).Picture = LoadPicture(App.Path & "\Images\some_image.bmp")
'or whatever else the path could be.

i have used your code and i still get an error on the.loadpicture line(error 13, type mismatch) anyone know why

VB Code:

Public Sub AddMorePictures(iCount As Integer)
CommonDialog1.ShowOpen
pictureload = CommonDialog1.FileName
    For i = Image4.UBound + 1 To iCount
        Load Image4(i)
       
        'Image1(i).LoadPicture pictureload
        Image1(i).Move 12, 34, 56, 67
        Image1(i).Visible = True
    Next i
 
End Sub

How could NOT see the CORRECT syntax I gave you more than once?
Here we go again:

this is what you have:
Image1(i).LoadPicture pictureload

this is what yiou NEED:
Image1(i).Picture = LoadPicture(pictureload)

yeah. thanks. i think my main problem was when it did work the coordinates were so small i couldnt see it well. but it works fine now apart from the image only loads once and if a new file is selected the old one is overwritten. do i just need to set up a for loop inside which could load new coordinates each time. Thanks again

Great! You're welcome. :wave:

so what about the problems i've got

How do you want to place new controls? Vertically or horizontally?

This way:

A
A
A
A
A

Or this way:

AAAAA

can it be done when the user clicks on a location on the screen a image is added

Would this sample work for you?

VB Code:

Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Load Image1(Image1.UBound + 1)
    With Image1(Image1.UBound)
        .Move X, Y
        .Visible = True
    End With
End Sub

yeah. thats great. havent tried it yet but looks good. thanks

NO problem.

that works great. a few problems to start with but all my fault as per usual. one issue still remains though. when you put an image in place it is always behind the richtextbox even when i have changed this using send to back and bring to front. any way round this. Thanks

Image control is a windowless control (doesn't have a hWnd property) and therefore cannot be on top of any window 9such button, rtb, picturebox, etc). You may either use Picturebox instead OR place Image control inside Picturebox control.

Just click on the ImageList on your toolbox bar and draw it inside of the picture control.

what does the ImageList logo look like i cant find it

ImageList is included under Microsoft Windows Common Controls 6.0.

I meant Image Control - not ImageList...

Simply select your Image control and press CTRL+X and then select your picturebox and press CTRL+V - typical Windows CUT and PASTE operation. :)

oh right. i'll try that

Actually, so did I. :blush:

so i put the imagebox in the picturebox but how do i need to edit the code so that they both move like the image did

anyone

this is an example using 2 pictureboxes (array members) and 1 RTB, posted by Rhino in some post, i modified it with RTB for you.

VB Code:

Option Explicit
 
Private Const WM_NCLBUTTONDOWN = &HA1
Private Const HTCAPTION = 2
 
Private Declare Function SendMessageLong Lib "user32" _
        Alias "SendMessageA" ( _
            ByVal hwnd As Long, _
            ByVal wMsg As Long, _
            ByVal wParam As Long, _
            ByVal lParam As Long) As Long
            Private Declare Function ReleaseCapture Lib "user32" () As Long
 
Private Sub Picture1_MouseDown(Index As Integer, Button As Integer, _
                               Shift As Integer, x As Single, y As Single)
                               
If Button = vbLeftButton Then
        ReleaseCapture
        SendMessageLong Picture1(Index).hwnd, WM_NCLBUTTONDOWN, HTCAPTION, 0&
    End If
End Sub
 
Private Sub rtb_MouseDown(Button As Integer, Shift As Integer, x As Single, y As Single)
If Button = vbLeftButton Then
        ReleaseCapture
        SendMessageLong rtb.hwnd, WM_NCLBUTTONDOWN, HTCAPTION, 0&
    End If
End Sub

it will also help you in moving the objects at run-time.

hope it helps you.

thats cool but for this line of the code

VB Code:

Private Function SetAlignment(lHwnd As Long, ByVal eAlign As ERECParagraphAlignmentConstants

user defined type not defined why is this

"ERECParagraphAlignmentConstants" TYPE is missing from your code. you need to declare it before that API.

and how do i declare that. sorry i'm not well up on that sort of stuff

could you please upload your code? i am sorry but i could not find this SetAlignment API anywhere, not even in MSDN? :confused:

what the whole project

if it is not possible, then atleast the form/module in which they are declared.

heres the form where the code is

it seems that you are in love with PictureBox. ;)

why are you using PicBox as a commondialog component and a RTB?? :confused: you have to put the RichTextBox component and the CommonDialog Component from the Components Dialog Box. they are shown as Microsoft Rich TextBox Control and Microsoft Common Dialog Control 6.0 in the list respectively.

and Cut-Paste the code i provided to different location "downwards" because you cannot declare TYPES after Subs and Functions. only comments or other subs, functions can appear after them.

i cannot test it because the SendMessageLong API doesnot work on Win 98.

can you explain that post i dont understand what you mean

all right, i changed the form and uploaded it for you.

changes by me:

1 - you used a Picture Box instead of a RTB. i deleted the Pic Box and used RTB instead.

2 - you used PictureBox instead of CommonDialog control. i deleted the Pic Box and used CDC instead.

3 - Added a command button to enable/disable the movement of RTB. please change it according to your use.

4 - just go through the code and you will see the difference i made in your code. it all commented.

hope it helps you. please respond if it does not work for you because i cannot test it since 98 does not support SendMessageLong API.

i think your Vb went weird because i had it set up right to start with

so how do i move the picture box

just checked my form was ok to start with
