Wpf - Maximum Custom Window Loses Drop Shadow Effect?
Feb 28, 2012
I have a custom WPF window defined as:
<Window x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" MinHeight="300" Height="350" MinWidth="600" Width="700" ResizeMode="CanResizeWithGrip" AllowsTransparency="True" WindowStyle="None">
I found a class online that creates drop shadows, shown below. This works well, even with a resize grip, until I maximise the window. Once I maximise the window or change the window state of another window (eg. Visual Studio), I loose the drop shadow and I cannot get it back.
[Code]...

So I made my form transparent by changing the transparent key to dimgray, change background color to dimgray. I also changed the picture box's BG color to dimgray everything was fine except that the drop shadow on the picture I did was just a grey blob.Is there anyway to make the drop shadow look like its a drop shadow?

Is there a way to remove the LineShape shadow effect when selecting the lineShape? I tried
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs)
Dim g As Graphics = e.Graphics
g.SmoothingMode = SmoothingMode.AntiAlias
Dim oldmode As SmoothingMode = g.SmoothingMode
g.DrawLine(_Pen, X1, Y1, X2, Y2)
g.SmoothingMode = oldmode
End Sub
but finally, this have some back effects on invalidation: when moving (in a panel) the line leave traces - does not invalidate properly.

I'm trying to create a shaped form with an attractive shadow effect by painting progressive alpha blended layers underneath the main visible form area (a background mask color has also been set to allow a shaped form). This is going well, but I have one major problem to resolve - the bottom shadow layer does not appear as the correct transparent shade - it always appears solidly as the background color / transparent mask color for the form.
Why does this bottom shadow layer not show up as transparent, and why is this color being shown when it is set as the transparency key for the form (and so should be invisible anyway)???[URL]..

So I came across this code that enables a drop shadow on a form in Visual Studio .NET 2008. The code is as follows:
Public
CS_DROPSHADOW As
Int32 = &H20000
[Code].....
I want to create a drop shadow on a group box though. What changes can I make to this and where must I insert it to do this?

I'm currently building an intranet engine for a project I've got on the go at the moment,and I'd like to save myself a little time by generating header images from code where possible, however, I'd like it to match our concept image.What I'd like to achieve is below:My issue is I've not the faintest how to create that from code. I can do the absolute basics but that's about it.I start to fall down when it comes to the gradient background and the drop shadow on the text. I can get away with positioning the text on the larger header image, so if it's not possible to generate the exact gradient I have there, then I have a work around for that, but what I really want to achieve is the text with the font and drop shadow.

I have a vb.net application that, when a short cut is pressed, a window pops up. I also would like to make it completely invisible, unless the short cut is pressed. In the default class that houses my code for noticing the short cut and coordinating the events of the short cut, I have placed the following code:
Me.ShowInTaskbar = False
I have isolated this code as the issue. The issue is that my application does not work when it is not shown in the taskbar. This is only the default form - for the pop up window I have a separate class. How can I create a workaround for hiding the window in the taskbar and hiding it in general?
Btw, this is my hotkey code:
Public Const MOD_ALT As Integer = &H1
Public Const WM_HOTKEY As Integer = &H312
Public Declare Function RegisterHotKey Lib "user32" (ByVal hwnd As IntPtr, ByVal id As Integer, ByVal fsModifiers As Integer, ByVal vk As Integer) As Integer

I am making a custom button control and am having some difficulty with my Text property. Anything I type in only stays while the form designer window is open. When I close the form designer and reopen it, my Text property resets to "". Also if I run the program, it loses the value entered at design time.
I also have an Image property for my control which is working just fine.
Here's some of my code:
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Windows.Forms

I have a picturebox that has a semi-complex image on it and also has a series of other pictureboxes, most of which are set to not visible. The way the program works, the user can click and drag a couple different items on the parent picturebox. The things they can drag are not actual controls, but parts of the image itself. That is all working fine. While testing, I had all of the subordinate pictureboxes (there are a variable number of them) visible showing a black background. I have now improved their implementation, so I changed the display so that only the subordinate pictureboxes that actually have something in them are visible. For all the others, they have .Visible = False.
The problem is that when I click and drag on one of the items in the parent picturebox, all the invisible pictureboxes become visible. They have no image in them, so they take on the color of the backgroud behind the parent picturebox. This is undesirable. I want the invisible pictureboxes to remain invisible during the drag and drop action. The one solution that seems promising is to set the image of all those pictureboxes to some transparent image such that, though they are visible, they will not appear as anything. A bit of testing shows that this technique would work.

I populate a listbox with locations search results, I then have 6 panels below the listbox each with a combobox containing all available locations. I want to allow the user to click on one search result in the listbox and drag to one of the 6 panels and set the combobox.selectedvalue = listbox.selectedvalue.
i have researched the drag and drop and have yet to figure out how to accomplish this. I think i could do it using some key down events etc. ?

I was trying to block the closing of a custom combo box popup window in my custom DataGrid. The popup window comes by pressing F4 or ALT+DOWN keys in my datagrid which is getting closed if I press the down arrow for the first time, after showing the first value in the combo box as selected. Next time onwards, if I press the F4 key and down arrow, I can move to any item in the popup window and select the item using keyboard and in that case, the popup window is not getting closed till I press the ENTER key or selection using the Mouse. Is there any specific reason for this behaviour or something is missing in my code part? [code]...

I am looking to close the application when I click a cancel button in a login page, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application. Here's the code that I have so far:

Public Event CloseApp As EventHandler

How would i create this for my toolbox, but use sockets with this item. or can it be as flexible as socket?
How would i do this? Would i need to add more or create a brand new socket with my mini drag n drop Client/Server Ex: MySuperEasyClient.ASCII.EncryptData.SendData(textbox.text)
ps: What would this be called? TCPClient/Server or UDP?

How would I re-size the window @ a point relative to its parent location and size. I am using code from Make an unowned window's parent to my form, to be able to set a windows parent to panel1.
Dim proc As Process
' Start the process
proc = Process.Start("C:UsersDmitryAppDataRoamingSpotifyspotify.exe")
proc.WaitForInputIdle()
Dim tmp_hWnd As IntPtr
[Code] .....
This works on most windows except for ones that are customized. Maximizing the window will maximize the window to bounds of the actual screen bounds instead of the panel1 bounds. Code works fine with normal windows but not with this one. (Spotify Window.)
