OK - VB6 is a dead language. You need to specify if you're using VB6, as people will assume .NET otherwise.

Hey All,
Was wondering if someone could shed some light on the use of the System.Drawing.ImageFormatConverter class in VB.NET (2005).
Could someone provide an example as I'm getting no-where:
dim pBMP = new Bitmap("c:\test.bmp")
dim pCON as new System.Drawing.ImageFormatConverter()
pCON.ConvertFrom(pBMP)
...Now where to?
Any help would be appreciated.
Thanks In Advance.
Lachlan.

Thanks,
The example in the link converts file formats, where my purpose is to convert the colors in the image from 24bpp to 16bpp bitmaps.
Therefore I believe I need the ImageFormatConverter.
Cheers
Lachlan.

The easiest way to do this is to create a 16bpp bitmap and draw the 24 bpp bitmap onto it. You can probably also use the color matrix to do this. In fact, the way to do it is just to strip the least significant bits of the red, green and blue component of each color. That is, if you wanted to build it yourself, which you probably don't.
The ImageFormatConverter converts between file formats, as in gif, jpeg, etc. So MSDN tells me, anyhow

hi KoolPrasad,
THE REASON WHY IT IS NOT DISPLAYING THAT MSGBOX WHEN U RESTART, IS U NEED TO ENABLE MACROS IN MS-WORD. ENABLE THE MACROS THEN IT WILL SURELY DISPLAY THE MSGBOX.
HOPE IT HELPS..

hi
To enable macros in MS word.. follow these steps..
open MSword->open Tools menu-> open Macros-> click on Security menu-item.
this will open the Security dialog box. now under the Security level Tab u will find three options.. now try clicking medium and Low options. first try using medium... hope it will solve ur proble.. else try using LOw. then close the document and restart it. This time u surely gonna get the msgbox.

This code is just an Example. And try to Change your code as per your Machine Specification.
Const WM_ENDSESSION As Integer = &H16<br />
<br />
Dim osexit As Boolean = False<br />
<br />
<br />
<br />
Protected Overrides Sub WndProc(ByRef e As Message)<br />
<br />
If (e.Msg = WM_ENDSESSION) Then<br />
<br />
osexit = True<br />
<br />
Application.Exit()<br />
<br />
End If<br />
<br />
MyBaseProc(e)<br />
<br />
End Sub<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing<br />
<br />
If osexit Then<br />
<br />
'Not doing anything will let the application close<br />
<br />
Else<br />
<br />
e.Cancel = True 'This will cause the application to ignore the close & continue running<br />
<br />
Me.WindowState = FormWindowState.Minimized 'Minimize the Window<br />
<br />
End If<br />
<br />
End Sub <br />

Hi Satips,
I am using the following chunk of code , which u provided.
Const WM_ENDSESSION As Integer = &H16<br />
Dim osexit As Boolean = False<br />
Protected Overrides Sub WndProc(ByRef e As Message)<br />
If (e.Msg = WM_ENDSESSION) Then<br />
osexit = True<br />
Application.Exit()<br />
End If<br />
MyBaseProc(e)<br />
End Sub
i had two windows opened with my project in which i am testing ur code(two internet explorer windows)
Control first goes to this function even before the form load.
This function executes consecutively three times
Now the problem is
After comleting the execution three times , it gives the following error
Error creating the window Handle.
So Where the problem can be ?
|
|
|
|
|
”Error Creating Window Handle” is a Win32 error, therefore the first thing you should look at the code that did any thing with Unmanaged code.
I think you will simply run out of window handles. How many controls are you using in your Application ?

Satips.

Hi,
I have Visual Studio 2005....all fired up to learn programming (I know nothing about code) and now know all the details of the IDE and how to use it. Can someone suggest a good book, tutorial or otherwise to learn to code in VB?....I got a book from Sams Publishing (which by the way I would never buy from again, they are a disgrace and the book was worse!) and it seems the whole 500 odd pages was about creating a crappy picture viewer which did help a little but a lot of wasted hours (craploads more than the 24 hours suggested by the INAPTLY named book...although it did take more than 24 hours to get the drm to work and so far it has taken in excess of 6 weeks to get an answer from sams OR the author..still no answer from either despite a number of progressively angrier emails).
So any suggestions would be great, Im happy to pay as long as its not a book from Sams...just looking for value for money. By the way it seems to be ridiculous to suggest that you could learn something like this in 24 hours and I would suggest that real programmers should ostricise these idiots for suggesting that something that has taken them years to learn and has REAL value could be learnt by anyone prepared to fork out 40 odd bucks for a crappy book and learn it in 24 hours! Just my 2 cents worth!
