Showing Clickable Control On Non Owner Window
Mar 16, 2009
I made the awful mistake of using a module instead of a class. Now, I have a control, (who inherit from a web browser), hidden under a modal form. And I need to show his content (and being it clickable) to the user, but it is hidden, and I don't want to mess with the Showmodal of the hinder form. Until I modify my code, so I can do multiple instances of my browser, I need to show that control to the user on a third form. I think that I can temporary change the .parent property of the browser, so a third modal form shows it.
But I fear that I possibly made the browser control hard coded as working in the bottom hidden form, so If I change his parent, I may broke some logic. Is there a way to show the control on a third form, without changing his parent? (and still have it clickable). I know I are asking for trouble. It is only a short term solution until I move all my module into an instantiate able class. (And I remember had being advised to work ever with classes instead of modules. Now I learn the lesson the hard way).

I was just googleing this, and i came across this
Dim p As New System.Diagnostics.Process
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
p.StartInfo.CreateNoWindow = True
p.StartInfo.UseShellExecute = True
p.StartInfo.FileName = "cmd.exe"
p.Start()
Does that mean that i could show it again? if so, is there a code that can do this?Also, if i wanted to get the window that the user is currently in, how would i be able to hide that?

I have a form (f1) and a popup form(p1). On f1, when I click on a button, I call p1 like such:
Dim spp As New p1
spp.ShowDialog()
and in p1, I have a progress indicator that shows a long running process. The problem is that p1 doesn't show. I tried invalidate, update, refresh, doevents, etc. (both in f1 as well as p1). Nothing. p1 just doesn't show.

I have 2 desktop programms..I will call them P1 and P2.So, P1 launches P2 as a process. However, at some point I want to be able to show a window in P2. My problem was that this window, when called, was showing correctly placed, in the middle of the screen, but in the back of P1.So, in order to show it as the top most window, above all others applications running on my computer, I used the windows API:
Const HWND_TOPMOST = -1
Const HWND_NOTOPMOST = -2
Const SWP_NOSIZE = &H1[code]...
Now the window shows on top of all other, but it is placed in the top left corner of the screen, resized to much small dimentions, that I cannot even see the controls on it.

I am trying to show a message box when an error occurs in a modal dialog window but for some reason the message box is never shown although I know the MessageBox.Show method is being hit. The try catch block is inside of an event handler for a windows form that is being shown as a modal dialog. I know that the event is being fired and that the error is being caught but the message box never opens. I've replaced the MessageBox.Show with another form show and it works fine but I'd rather use MessageBox instead of creating my own error form. I just can't seem to make MessageBox work. Is this a limitation of MessageBox? Here is a simplified version of what I am doing:

I am trying to find the handle of the child window for the Yes button in the User Account Control window so i can click it. This window has a structure with a few child windows with the same name.
Dim hwnd As IntPtr = FindWindow(Nothing, "User Account Control")
Dim hwnd2 As IntPtr = FindWindowEx(hwnd, 0, "DirectUIHWND", vbNullString)
Dim hwnd3 As IntPtr = FindWindowEx(hwnd2, 0, "CtrlNotifySink", vbNullString)
Dim hwnd4 As IntPtr = FindWindowEx(hwnd3, 0, "Button", "&Yes")
There are multiple CtrNotifySink with its own Button child window or other child windows. How do i search thru the different CtrNotifySink window to find the one that contain the Yes button so i can send a click to it? I do need to find it before i can send a click, right? because i try just sending it to the main window with sendmessage and nothing happen.I even try sending it directly to the handle found by spy++ of the yes button with bm click but nothing happen?

My Front end is VB.net 2008.I have a form. In this form, I have a menu control, this menu control has four buttons.On clicking the first three buttons, open the window with Show() event. and the fourth button open the screen with ShowDialog().Now, One by one I am clicking the button , so finally i have now four windows of this application.(Three with Show() and one with ShowDialog())Right?
Now I am minimizing all the windows with the help of Window + D Button.After this, If I use the keyboard(Alt+ Tab) keys. This is opening the showDialog window on top because , Show dialog's TopMost = True.Now I come back to my problem. That's why I cannot use the show/Showdialog overloaded menthod to pass the Me/form-id .Again, I use the keyboard(Alt+ Tab) keys, to minimized all windows. In the taskbar and Startmenu properties ,I have selected the Group Similar Taskbar buttons.This resulted in the heap of my application windows, one on the other.Now i click on one of my application window , and If I click the window other then the Show Dialog opened Window, this is not bringing the show dialog window to topMost.
Note:- There is no parent child window requirement. That's why I can't use the Show/Show Dialog overloaded method to pass the Me/Form-id

I am currently working on a launcher, and it must consist of the following:
- one main routine being called, NO WINDOW may be created at any times after or before this main routine.
- one small form called by the main routine if a certain command was sent through the Command (shortcut).
At this point I use a Windows Form, but it seems a little useless to create and initialize a form if you won't even use it. Any way to make a routine run when my program starts without showing any window? But still make it possible to show that small dialog?
I did this at first but it seems a bit dangerous:
'NOTE: The following procedure is required by the Windows Form Designer 'It can be modified using the Windows Form Designer. 'Do not modify it using the code editor.
<System.Diagnostics.DebuggerStepThrough()> _
Private Sub InitializeComponent()
Main()
End Sub
Sub Main()
'Code to run here
End Sub
It starts another program (process) which has a GUI, so I do not want to display a console window.

I made a simple extension of the PictureBox control. In retrospect, this might not have been the best starting point, but that's currently irrelevant. This is the first time I have tried extending a picturebox control. The point of the exercise was to attempt something odd, but I haven't even gotten that far. The control shows up in the common controls panel, and I can drag it onto the form, but it doesn't get added.
What am I doing wrong? There is very little code behind the new control at the moment, as I am just trying to test a concept, and what code there is doesn't actually get run because the control is never created, so NO code gets run.

I created a form using the TabControl and was playing around with the layout. I want to have the Tab and Tabs body to be transparent whether on that tab or not.
Now I changed the DrawMode to OwnerDrawFixed which gives me the look I want but unfortunately now the text disappears.
I have changed the fonts and colors of the text but when set to OwnerDrawFixed the tabs are all blank even though I have text written in the properties.
1. Is there a way to change the default white background for the focused tab without setting the drawmode to OwnerDrawFixed
2. when it is set why is my text not showing?
Here is a visual of what I mean:
I am using a windows 7 system.

I'm using the Microsoft Chart Controls for Microsoft .NET Framework 3.5 and am having a spot of trouble getting Data Markers to show on the image.I'm generating the chart at run-time, so can't just use the designer.
Sub New()
MainChart = New Chart
MainChart.Size = New Drawing.Size(500, 200)

Which all works lovely, and I get pretty charts.The only problem is that there are no markers on the datapoints.

i have a RTB control on a form showing rich text
At the top of the RTB i have a toolstrip with bold, italic, and underline buttons - these work just fine. However i need to add some color buttons, i dont need a color picker since i only need 3 colors - Black, Blue, Red. So i added some buttons for these, however i cant get the buttons to work... my syntax is wrong. I also dont want the color buttons to remove any other formatting from text (like bold, underline, etc) - i achieved this for the other buttons like so:
Private Sub BoldButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BoldButton.Click
NotesBox.SelectionFont = New Font(NotesBox.SelectionFont,

I have a autocomplete dropdownlist(ddl) in my app. When ever I click on the ddl and start typing to find the item I am looking for in the ddl. The ddl is expanded to show all the orders when typing. After I press the enter key to go out and get the order information for that order the Order number in the ddl is missing but here is the weird part. When I don't have the ddl expanded but still have focus on the ddl. When I find the order I need and press enter. The order number is showing in the ddl as the selected one after it has loaded up the order information.
