Screenshot Still Captures Invisible Form?
May 22, 2009
I'm working on a project, and one thing it's supposed to do is make itself (the form) invisible, take a screenshot of the current screen, and the make itself visible again.[code]I made the 'FinishScreenshot function to call the 'TakeScreenShot' function, courtesy of AdamSpeight2008 and save that result as a specified image file in a specified location. the problem is, the screenshot ends up usually showing the form that was supposed to be invisible, but sometimes not (usually on the first form). I'm guessing this is because the FinishScreenshot and Take ScreenShot functions aren't finished working until after the form becomes visible again, but I'm not sure.

I am currently using a DevExpress (10.2) Banded GridView within my Visual Studio 2010 project. It works great except I was have an area where I allow the user to choose which columns they want visible or invisible. I noticed that if I make all the columns within a band invisible the band still remains and gives an empty column in my grid. I was wondering if there is some way to automatically

So I'm trying to take a screen capture of the windows form and display only a certain specified area of that screen capture in a picturebox on a different form. Kind of like this. First, take the screen capture of the form: Then get a specified area of that form through x,y coordinates or something and display it on a picturebox on a separate form.

I know how to take a screenshot, but how can I take a screenshot of the screen behind my form without hiding the form, taking the screenshot, then showing the form again?The reason I can't simply hide the form to capture the screen behind it is that I need to take the screenshot repeatedly, and hiding the form each time I need to take the screenshot would cause the form to flicker.
Here is the code I'm using now:
Me.Opacity = 0 ' Hides the form. Can't use this!
Dim bounds As Rectangle = Me.Bounds
Dim screenshot As New Bitmap(bounds.Width, bounds.Height, Imaging.PixelFormat.Format32bppArgb)
Dim g As Graphics = Graphics.FromImage(screenshot)

I am using VB.Net and I'd like to ask how could I make my form invisible while the other objects on it are visible? When I set the form's opacity property into 0%, the objects on it are affected.

I understand the properties to change a button from visible to invisible, but I need to be able to have two buttons alternate visibility when the first button is clicked.It's for a game. The first button is to "Begin Game" and on open, the invisible button that sits over it is called "Begin Again" which I would like to only appear once the Begin Game button has already been clicked. This would then trigger the "Begin Game" to become invisible.

So I have a program that only has one form in it, this form is just an "About" window that appears when a specific context menu item is clicked from the system tray icon (NotifyIcon) that is on the form.
All I want to do is make it so that when the program is launched, the form is not displayed at all and just the system tray icon appears.
I have accomplished this by doing the following but just wondered if there is a better/easier way?
1. Set the Opacity of the form to 0 in the designer
2. Set the ShowInTaskBar property to False in the designer
3. Use a timer that is started in the form Load event to call Me.Hide after 1 second
Then when I want to show the form I just set the opacity back to full and call Me.Show

Still using VS 2005. My concept is to use the same form space to display different "pages", like a "wizard" where you click the [Next] button, and the current UI disappears and a new UI appears. I want to "turn off" multiple controls and "turn on" multiple other controls. Example code: -
Private Sub
Button4_Click(ByVal

I am running a oracle package's procedure which raises raise_application_error (). i.e Oracle sends the application error to Visual Basic 6.0 . After executing procedure, When I try to display the value of Err.description in immediate window it prints only 532 characters.. rest of the characters are truncated. Is there any limitation that Err.description would capture only 532 characters? When I run that procedure in SQLPLUS, it gives entire string without truncation.
Please guide me to display entire string in VB using Err.description when error description posts to VB by Oracle PL/SQL raise_application_error.

I'm a computer science student and I have a project to do where I need to have VB connected to a webcam to take captures of items and then save them according to the item name that stores them into either a dbase or access database. I have knowledge of oledb using vb to retrieve and modify access databse so it might be better to head in that direction, but I have no clue how to get the webcam talking to vb and see the live feed from the cam until you take a picture and save.
