Hi,
I am trying to take a screen shot of a form without displaying it to the user. Here is the code:
Public Sub TakeScreenShot(ByVal windowHandle As IntPtr)
Dim screenBmp As Bitmap
Dim gfxScreenshot As Graphics
'Set the bitmap object size to the size of the form
screenBmp = New Bitmap((Screen.FromHandle(windowHandle)).Bounds.Width, (Screen.FromHandle(windowHandle)).PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb)
'Create a graphics object from the bitmap
gfxScreenshot = Graphics.FromImage(screenBmp)
'Take the screenshot from the upper left corner to the right bottom corner of the form
gfxScreenshot.CopyFromScreen((Screen.FromHandle(windowHandle)).Bounds.X, (Screen.FromHandle(windowHandle)).Bounds.Y, 0, 0, (Screen.FromHandle(windowHandle)).Bounds.Size, CopyPixelOperation.SourceCopy)
'Save the screen shot
screenBmp.Save("C:\test.jpg", ImageFormat.Jpeg)
End Sub
But what it ends up doing instead is taking a screenshot of the whole screen without the form! How can I fix this?
Thanks in advance!

Try this:
Dim Pic As Bitmap<br />
Dim SS As Graphics<br />
<br />
Pic = New Bitmap(me.width, me.height, Imaging.PixelFormat.Format32bppArgb)<br />
SS = Graphics.FromImage(Pic)<br />
SS.CopyFromScreen(me.location.x, me.location.Y, 0, 0, me.size, CopyPixelOperation.SourceCopy)<br />
<br />
pic.save("C:\test.jpg", ImageFormat.Jpeg)

its giving a few probs:
a) If the form is in the background then the screen shot contains an image on the contents of the screen rather then the form. I want to take a shot of the form while having it in the background.
b) Sometimes it just gives a plain white image. Any idea why that would be?
Thanks.

You will need to distribute the Crystal Report Merge Modules with your app. You can get them from the BusinessObjects.com website

Hi,
runtimes files on the target machine are required, you could distribute the required files by building a setup project (File > Add Project > Setup ...)
Right mouse on the Setup Project in the Solution explorer window > Add > Merge Module... > select Microsoft_VC80_DebugCRT_x86.msm
for more details plz go to http://msdn2.microsoft.com/en-us/library/ms225293(VS.80).aspx[^]
Good Luck  ,

It's nice 2b important, but it's more important 2b nice...

Nope, this Merge Module contains all that is required

can i know how to save the time a card is scanned using vb.net.
example: a employee scan their id card and the system need to save time the card was scanned and save it in the database.
can it be done?
|
|
|
|
|
Depends, obviously the card reader can detect when a card is scanned. In this case you should be able to have a feild in your database that is set as a datetime and then simply update it with datetime.now when the card is scanned. You can find out how to do that in google.

Add a timer to your form and on Tick event add this code
LableName.Visible = Not LableName.Visible
Hope this helps.

I'm currently working on a VB.NET project that requires several different types of items to be dragged on to a listview control (to put it very simply).
E.g. currently I have it running so I can drag a file from windows explorer on to the listview and a new listviewitem is created with the file name as the item text.
The problem I'm now encountering, is that I need to be able to drag treeview nodes from an existing old Visual Basic application (which has several treeviews), on to the listview in the new application. I have the source of the Visual Basic app so that can be modified if need be.
At the moment it's set up (not by me) so that items can be dragged between the various treeviews within the Visual Basic app, but I can't get it to recognise dragging *out* of that application on to the new one.
Any help would be greatly appreciated, let me know if you need more info...

The treeview may need to have the drag and drop enabled. From there you have to capture the events that fire when drag and drop occurs.

Why does the Child form always appear behind the other controls on the form?
|
|
|
|
|
Because the MDI CHild formis being rendered inside another control on the Parent form, called the MdiClient. Putting controls on the surface of an MDI Parent will always have them show up on top of this MdiClient control.

Hi,
I've been trying to work out how to iterate through a collection object using reflection.
I have a class with a few simple objects, strings, single[] arrays, and one collection.
However, when I'm using the GetFields() method to retrieve the objects in my class, when it gets to the collection I am unable to view all the items in the collection.
dim coll as collection = FieldInfoObj.getvalue(obj)
console.writeline("Collection has " & coll.count & " items in the collection")
for each item as object in coll
do_stuff(item)
next
Although it correctly states that I have 4 items in the collection, item 1 is Ok. item 2 is 'nothing' and item 3 causes an error. But I do actually have 4 'singles' in the collection.
How do i access the collection objects using reflection?
I *think* I need to reflect into each object seperately, and not just iterate through them after setting the main collection object using the getvalue(obj) method as I would with the other system.xxx type objects (which work fine)
Could anyone provide a simple example of how to iterate through a collection using reflection?
Thanks in advance,
Phil.

Hi,
I am calling a web services in VB.NET. The code is almost done but I am getting an error at shipping section that I don't know how to fix. I think it is very simple but I don't know how to figure it out.
Error is “Too many arguments to ‘Public Sub New()’ at value 1” at this line “Shipment.ShipmentItems = New ShipmentItem(1)”. I am not still sure that this is the right way of calling shipment class because shipment is a sub-class of salesorder.

The error is telling you that your call to "New ShipmentItem" shouldn't have (1) on the end of it.
Whether or not you are using it correctly is for you to decide.

Thanks for looking at this issue.
If I remove (1) from 'New ShipmentItem(1)' and make the line like this
Shipment.ShipmentItems = New ShipmentItem
then this error is coming.
'SendOrdersToSC.SalesOrder.ShipmentItem' cannot be converted to '1-dimensional array of SendOrdersToSC.SalesOrder.ShipmentItem'
What I should do?
