System.Drawing - Minimize Window Or Drag It Out
May 12, 2009
...
Dim Desen As System.Drawing.Pen
Desen = New System.Drawing.Pen(System.Drawing.Color.FromArgb(vectorCulDrLn(0), vectorCulDrLn(1), vectorCulDrLn(2)), drwgln)
Dim Grph As System.Drawing.Graphics = programNods.CreateGraphics()
[Code] .....
If I minimize the window or drag it "out of the screen" the "inserted" lines will be "cleaned"...
How can I draw them again? OR
How can I draw them in such a way to not lose them after I minimize the window or drag it "out".

I am making a web browser using geckofx. I have put the favicon in a picture box but I have changed my mind and now I want it as the form's icon. The code for the favicon is:[code...]
The favicon works fine in the picture box but i think it will look better as an icon. If i change the line Me.PictureBox1.Image = favicon to Form1.icon = favicon I get the error Value of type 'System.Drawing.Image' cannot be converted to 'System.Drawing.Icon'. How can I get this to work?

If you have ever noticed in the Task Manager, when you right-click on the running task, you have many options which include 'Minimize' and 'Maximize'. Is there anyway to do achieve this in vb?

If I show a new non-modal child window using .Show(frmParent), and then the parent window is minimized, the child will get minimized automatically as well.

Here's the scenario, winforms application, monitoring via Task Manager Processes Tab.On initial launch spins up to ~61,000K (initial data grid and data loads)If I minimize the application, not touching or doing anything the Mem usage drops to 1,380K.When I restore the application is spins back up to only 5.8K
So my question is, does the minimize send some internal message to clean up resources since the application in question is not in focus?The first app I noticed this in happens to be VB.NET, but I've observed the same behavior in my main C# winform applications.

I've looked all over the internet and did a search on Dreamincode.net but I can't find anything on minimizing to the tray for Vb 2008.What I want to achieve is if the user hits the "X" button at the top, the application should minimize to the tray. When I right-click on the icon, a context menu strip should appear.

I have a program that creates a Treeview from information procured through an ODBC query and dumped into a dataset. I have three such queries set up via radial buttons as well as a refresh button that triggers whatever radial button is active at the time it's clicked. The purpose of this program is to allow drag-and-drop of selected nodes, ending with a post to the database that officially makes that change of assignment to the new node.

I'm trying to create a program that when I press the X or _ buttons on the form it minimizes to the notification area(system tray). I did find some stuff but didn't understand were to put the code I just have some basic knowledge in VB.net. What I read was something about the formclosing event
Private Sub frmMain_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Me.WindowState = FormWindowState.Minimized
e.Cancel = True
'Me.Visible = False
End Sub
and well it sort of works to what I want but don't know were to go from there.. what I read from another post was that I had to do something with "NotifyIcon Class" but still didn't know what to do with that or where to put the code.
Basically what I want the program to do is minimize to system tray and a tooltip will pop up when I hover my mouse over it and display something that I want. Also when I right click the icon I would like some options to be displayed so that I could program it to close.

I made a program with Visual Basic Express 2008. I got this error message when I try to close my program after running it. (PS: It is a simple code that can login into Microsoft SQL Server)The error message shows the error was caused by the "system.drawing" (Parameter is not valid). Also, I have been trying the code in VBA (Excel). When I tried to close Excel after running my code, I got the same problem (Microsoft Excel has encountered a problem and need to be closed.....) and the error report shows the error was caused by "system.drawing" as well.

I'm attempting to make a program that will simply draw a guide (consisting of two perpendicular lines) on another program's window. I tried using a form with a transparency key and TopMost set to true, but then whenever the user inadvertently clicked the guide, it would un-focus the application. The only lead I could find was a suggestion to "Draw directly on the other application's window". I can't find anything that tells me how to do this, or if its even possible...
So I need to know one of three things:
1) Is it possible?
2) How do you do it? or
3) is there some way to make a form completely un-focusable?
The effect I'm trying to get is so that it looks like someone physically drew the line on the monitor itself.

I have a bit of an issue here. I made a "Colour picker" dialog in my program with which you can pick the colour at the mouse. It is a simple topmost form with an OnPaint handler used to draw a coloured border around the cursor:
It uses a transparency key to make the non-drawn parts of the form transparent.
It uses the following code to prevent the mouse from clicking through the screen:
Window.FromControl(Me).ExStyle(Window.ExStyles.Layered) = True
Window.FromControl(Me).ExStyle(Window.ExStyles.Transparent) = False
It sets Layered to True and Transparent to False. This works in Windows 7, but on a XP machine it fails. When moving the mouse the event does not go to the forms' event handler and you can just click through. For a screen region selector I simply made a screenshot, but I want the Colour Picker to remain updated. (just in case you want to get the colour of an animated control)
How can I get this to work on a Windows XP machine?
