PictureBox.hdc?

VB Code:

Public Declare Function TextOut Lib "gdi32" Alias "TextOutA" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long, ByVal lpString As String, ByVal nCount As Long) As Long
 
Public Sub Text2Picture(ByVal sString As String, ByVal PicBox As PictureBox, Optional ByVal posX As Long = 0, Optional ByVal posY As Long = 0)
    TextOut(PicBox.hdc, posX, posY, sString, Len(sString))
End Sub

I use this code in vb6 to create an image from a string of text... when i try using it in .NET it tells me - " 'hdc' is not a member of system.windows.form.picturebox" - how do i go about this?


cheers
si

.NET has something new called GDI+ that handles all graphics stuff which is probably what you need. I dont know alot about it yet, but I just wanted to give you the keyword to look for. Try searching the net for GDI+ if you dont get a better answer.

oh fun :rolleyes:

:p
cheers i will look into that :)

your welcome. In fact, now that I think about it, there is a Text drawing class in GDI+. Dont remember the namespace, but I know it exists.

yea i noticed that... I did a search and mostly it was only for C# or ASP :(

see if this helps any

thanks :)

whats this Protected Overrides... new to me?



been visiting Programmers Heaven recently mate?

Nah ..havent been around PH for awhile. Not much happens around there. :p

Protected means the procedure can only be called by a class that inherits the class the procedure is in.

Overrides tell the system to to run your procedure in the case of another procedure of the same name, that can be overrided, being called. Sort of like sub classing. In short your procedure takes precedent over the other.

ok cheers, that code seems what i want sorta


I want to beable to put the image into a picture box, and save it (2 different steps) ... just what do i replace for the 'e' varible if i put it somewhere else


oh frig this is confusing :confused:

the e parameter is only for Subs/functions that are called by an object. In other words an event and is a collection of arguements for an event.

Im not sure what you mean by replace it if I put it somewhere else.

well nore do I really, confused myself

VB Code:

Protected Overrides Sub OnPaint(e As PaintEventArgs)
    Dim g As Graphics = e.Graphics
    e.Graphics.FillRectangle(New SolidBrush(Color.White), ClientRectangle)
    g.DrawString("Hello World", Me.Font, New SolidBrush(Color.Black), 10,10)
End Sub

that code works fine and dandy, thou paints it on a form, whereas i want it in a picturebox, also i want to beable to call on it as a sub procedure so somit like

Sub Text2Pic(sString as String, picBox as Picturebox, Font as Font, FontSize as Integer)

yea, i know its vb6 but that is what i am trying to get to thou

hmmm. Well let me see what I can come up with. ill give it some thought as time permits.

ok cheers, another small thing, do you think its possible to display a font which isnt installed on the system, thou i have the .ttf file? Ive just downloaded that free book someone posted, im gonna have a quick read thru that and see what I come up with :)
