Show Images in RichText Box?

I need to be able to insert a picture into a RichText Box. Is it possible?

Yes.... give me a sec.

Try this:

Umm... doesn't work.

I added the components Richtext Box and Windows Common Controls and I get my first error on
Form_Load
RTB.TextRTf

What's the error?

Let's try with the whole project...

lol
Sorry I forgot the most important part.

Method or Data Member Not Found

I'm guessing you haven't done whatever it is that you have to do to make the Picture box think its a Rich TextBox

What controls are meant to be on the form??

Cause you didn't inlucde the Project file so....

Download the last ZIP... I included the project file as well

Aah works perfectly!!!

Thanks a million :)

You're welcome.

Ohh.... I'm using the following code to send a picture to it

VB Code:

Private Sub Text1_KeyPress(KeyAscii As Integer)
If KeyAscii = 13 Then
RTB.Text = RTB.Text + "<(BugFix)>"
PasteImages
End If
End Sub

But it takes the Image which is already there any moves it to the new postion. Is it possible to have multiple images?

Yes... but you should "load" all the "<(BugFix)>" first, and the call the PasteImages.

You might add images interactually with a similar code if you want.

Try this:

VB Code:

Option Explicit
 
Private Declare Function SendMessage Lib "user32" _
Alias "SendMessageA" (ByVal hwnd As Long, ByVal _
wMsg As Long, ByVal wParam As Long, lParam As Any) _
As Long
 
Private Const WM_PASTE = &H302
 
Private Sub Form_Load()
    RTB.TextRTF = "This image <(BugFix)> is a BugFix"
    PasteImages
    
End Sub
 
Private Function ParseFirst(Text As String, lStart As Long, lStop As Long) As String
    ParseFirst = ""
    lStart = InStr(Text, "<(")
    If lStart Then
        lStop = InStr(lStart, Text, ")>")
        
        ParseFirst = Mid$(Text, lStart + 2, lStop - lStart - 2)
    End If
End Function
 
Private Sub PasteImages()
    Dim i As Integer
    Dim e0 As String
    Dim lStart As Long, lStop As Long
    
    RTB.Tag = RTB.Text
    Do
        e0 = ParseFirst(RTB.Text, lStart, lStop)
        If e0 = "" Then Exit Do
        'clear clipboard of any data
        Clipboard.Clear
        
        'save pic to clipboard
        Clipboard.SetData ImgLst.ListImages(e0).Picture, vbCFBitmap
            
        Do Until RTB.Find("<(" & e0 & ")>") = -1
            RTB.Locked = False
            RTB.SelStart = RTB.Find("<(" & e0 & ")>")
            RTB.SelLength = Len("<(" & e0 & ")>")
            SendMessage RTB.hwnd, WM_PASTE, 0, 0
            RTB.Locked = True
        Loop
    Loop
End Sub
Private Sub Text1_KeyPress(KeyAscii As Integer)
    If KeyAscii = 13 Then
        RTB.TextRTF = RTB.Tag + "<(BugFix)>"
        PasteImages
    End If
End Sub

Ok.... have u tried it with heaps of pictures.... it gets abit weird.

I removes the icons from the screen and then redoes them... so you can see the <(BugFix)> Text. Scrolling works fine... but everytime the user enters some thing

An example might be holding Enter in the above example.

I'm guessing its not possible to fix this.

My computer is too fast to see that, anyway!!

Oh ok :D

I'm running a Cel 1.1.

Its because your clearing the text and reinserting the pictures

The problem is is that I have to run this on a P110

Hopefully it'll be usable.

I've replaced the Bitmap with a Gif and I get an error on,

VB Code:

Clipboard.SetData ImgLst.ListImages(e0).Picture, vbCFBitmap

What do I need to change it 2? I had a look under help and it didn't show me anything to useful.


Should I just convert the Gifs to Bitmaps?

Come on Guys, nearly done!! :D

Ok... I tried to put this in my Chat Program, and I got an error when I try to insert a Gif or Bmp instead the image that you included in the Image List.

Urgh what do I need to change??? :mad:

Heres the my Project is you guys are feeling really helpful.

Ok, I've gotten rid of the Image List, so now I'm just using a Picture Box.

Now the Problem is that its possible to resize the picture

Is it possible to change this?

Are you talking about the Autosize property?

No...

When the image is pasted into the RichtextBox, the user can resize it, which is not good.


Also, how can be able handle more than one picture? (like what do I need to change in the parser?

Thanks in Advance.

Bump

ok i had the same problem with "resizability". The only way i was able to get around this was to prevent people from highlighting the text. Whenever they would onmousedown or onmouseup, i would set the selection length to zero. This prevents resizing.

Yeah... good idea.

But how can I allow for more than one picture?? Just create multiple parsers?? :confused:

Thanks in Advance.

i had them in the onmousedown and onmouseup properties of the richtextbox. However, it prevente highlighting ANY text.

For what I want to use it for, locking it is fine.... can't believe that I didn't think of that early. :D

But now all I need is the above code being able to handle mutliple pictures.


Its easier to replace the imagelist with picture boxs I found.... if anyone cares. :D

Yet another *--------BuMp--------*

Noone...?? Surely it can't be that hard.....

I guess, you can paste it anywhere... the secret are in these lines:

VB Code:

RTB.SelStart = RTB.Find("<(" & e0 & ")>")
    RTB.SelLength = Len("<(" & e0 & ")>")
    SendMessage RTB.hwnd, WM_PASTE, 0, 0

You have to select the place where you want to place your image, and paste it

I reallize that this thread is very old but i was wondering if somthign can be changed with this solution? This code processes all the richtextbox text and then researches it to replace the given strings with an image by paisting. What i was wondering is if you can make this process only the text between the last 2 vbCrLf and still keep the original text and images before these 2 vbCrLf

Any ideas?
