The stream must be in BMP (bitmap), JPEG, WMF (metafile), ICO (icon), or GIF format.

Hello, I'm not sure what the rule is on double posting here so I'm sorry if there is one. Just thought id let twisted know something.

This code might interest you, allows you to loads a picture from a url to a picturebox.

Private Type TGUID
Data1 As Long
Data2 As Integer
Data3 As Integer
Data4(0 To 7) As Byte
End Type

Private Declare Function OleLoadPicturePath Lib "oleaut32.dll" (ByVal szURLorPath As Long, ByVal punkCaller As Long, ByVal dwReserved As Long, ByVal clrReserved As OLE_COLOR, ByRef riid As TGUID, ByRef ppvRet As IPicture) As Long

Public Function LoadPicture(ByVal filename As String) As Picture

Dim myTGUID As TGUID

myTGUID.Data1 = &H7BF80980
myTGUID.Data2 = &HBF32
myTGUID.Data3 = &H101A
myTGUID.Data4(0) = &H8B
myTGUID.Data4(1) = &HBB
myTGUID.Data4(2) = &H0
myTGUID.Data4(3) = &HAA
myTGUID.Data4(4) = &H0
myTGUID.Data4(5) = &H30
myTGUID.Data4(6) = &HC
myTGUID.Data4(7) = &HAB

On Error GoTo LblError

OleLoadPicturePath StrPtr(filename), 0, 0, 0, myTGUID, LoadPicture

Exit Function

LblError:

MsgBox Err.Description

Set LoadPicture = VB.LoadPicture(filename)
End Function

Also if you would like me to convert any code from vb.net version to vb6 i am more than willing to.

Nah nah its cool.
But by the looks of things that loads a picture from a image file on your computer, And i tried to do this, It only worked for as i said files already on the computer. I was looking for ones that load of the internet kinda like the code that you just gave me except it work's for links like:


Image1.Picture = VB.LoadPicture("http://garcya.us/images/car-wallpapers19.jpg")


Thats a link to a car, I didn't work with the code it gave me an error.
But once i downloaded it put it in C:/ i just change the code to.


Image1.Picture = VB.LoadPicture("C:/car-wallpapers19.jpg")


And it worked great.

So in other words do you have a code like this, but loads of an image from a URL rather then a location on your Computer?

P.S
I just found out with your code you can adjust the size, color depth, and the X and Y coord's for the picture.
Nice .DLL there lol.

Que malo eres

Si solo es un API como quieres que se haga de otra forma? Que cargue el type con dos Currencys? Tal que asi:

Código (vb) [Seleccionar] Expandir

'OLEAUT32
Private Declare Function OleLoadPicturePath Lib "OLEAUT32" (ByVal szURLorPath As Long, ByVal punkCaller As Long, ByVal dwReserved As Long, ByVal clrReserved As OLE_COLOR, ByRef riid As GUID, ByRef ppvRet As IPicture) As Long

Private Type GUID
   cData1  As Currency
   cData2  As Currency
End Type

Public Function GetImage(hURLorPath As String, Optional TransparentColor As OLE_COLOR = vbWhite) As StdPicture
   Dim uID     As GUID
   
   With uID ' // StdPicture GUID {7BF80980-BF32-101A-8BBB-00AA00300CAB}
       .cData1 = 116045007755044.6976@
       .cData2 = -612146501409303.8709@
   End With
   
   Call OleLoadPicturePath(StrPtr(hURLorPath), 0&, 0&, TransparentColor, uID, GetImage)
End Function

No hay mucho que hacer en la llamada a un API, asi que no seas malo
