Forms :: Disabling Close Window Option In Windows 7?
Apr 13, 2011
I have an application developed in VB.net with 3.5 framework. I have disabled close (X) button on the main form of the application while doing some processing. I have achieve disabling by "Overriding ReadOnly Property CreateParams()" of the form. This is working fine as both control button on form and close option on right click in the taskbar shows disabled. This fulfill my needs on the Windows XP OS but not on Windows 7 OS. As in Windows 7 right click on application icon in taskbar shows a different menu, which has a new "Close window" option.
The close in original menu still shows disabled (this old menu is hidden but can be shown by holding Shift key and right click on the application icon in taskbar). Now I need to disable this "Close window" option as well and only for my application.Is there a method through which I can do this programmatically.

I am trying to work on an application that disables the close button (X) on the upper right hand corner of a window. In order to do that I need to use calls to API methods like GetSystemMenu, EnableMenuItem and RemoveMenu. I can figure out how these methods work but there are certain parameters that these methods have whose values that need to be passed to them as argument is unknown to me. How can I know them.
E.G.- for EnableMenuItem, the parameters are- hMenu (handle to the menu), uIDEnableItem (The menu item to be enabled, disabled, or grayed), uEnable (This parameter must be a combination of at least two of the following: MF_BYCOMMAND or MF_BYPOSITION MF_ENABLED, MF_DISABLED, or MF_GRAYED)Now when I call this method from my application I supply the current window handle as the first argument, the item no. to be disabled/enabled as the second argument but I CAN'T UNDERSTAND WHAT TO SEND AS THE THIRD ARGUMENT. What exactly are the possible values for those parameters- MF_BYCOMMAND or MF_DISABLED. I checked certain examples where they are supplying hexadecimal values like &HF060, &H1, 0x400, 0x1000, 0x2 etc. or integer values like 1024, 2 etc. But how would I know what exactly these values are and when to use which value.The same problem arises in case of calling RemoveMenu method.
how u can disable the X(close) option on a form in VB?? i dont want the user to be able to close the form that will be running and need to disable the X to be able to do this.

I am making a System Tray Application when i minimize my form its hide itself in the tray but whenever i click on the tray icon my form shows now when my form shows up i would like to disable my Background desktop same as CardSpace when its shows up.
I'm in the process of converting a VB6.0 application to VB.Net (2008 Express). I have a MDI parent form, I'll call mdiBackground, and 4 MDI child forms, frmStatus, frmShow, frmQwerty, and frmSentence.The layout is as follows:mdibackground - has the menus at top and is a container for the child forms.frmSentence - appears at the top frmShow & frmQwerty - appear at the left and when one is closed the other one is in the same position.frmStatus - appears at the right, it has buttons which control when frmShow and frmQwerty are to appear I have a couple of regular forms that act as dialog forms. The Me.Close() works fine on these.
I created a new windows form application using VB 2010. I added no controls to the form. This is right "out of the box" app created by the VB windows form app wizard. I next added a FormClosed event handler. The handler gets called whenever I click the "x" on the form.Later I needed to close the form programatically in response to an event from an automation client. So I did something apparently farily dumb. I called "Me.Close()" Nothing happens. The form stays up on the screen. My FormClosed event handler is NOT called.The MSDN entry for "Close" doesn't give me a clue as to why this call doesn't work. Indeed, it seems to imply it should work.So I added a couple of lines of code after calling "Close()" since when I stepped across that line of code it appears that no other code would execute. Sure enough, as soon as I step over the call to Close(), I cannot step through any other lines of code.
Then I found another piece of form code while searching around and I found the code had what appeared to be an odd keyword just dangling in the code. The keyword, colored by the IDE as a VB keyword?So I typed "End" into my method and intellisense shows me "End Statement. Stops execution immediately". And it does. But is my FormClosed event handler called. No.I added "Inherits System.Windows.Forms.Form" to see if that had any effect. No change.So how does a form close itself programatically?
when I got home to try out the method in the above post in my real application things did not work out.The big difference is that my main form is a MDI. When I open my edit form, it's mdiparent is set to the main form. When I click 'edit' and then disable "me" the entire application goes modal.I was expecting only the MDI child to go disabled, not the whole application..Basically, I want only the MDI child window that opens it's "edit" dialog to go disabled..
I have written a little helper app that mostly does various text operations on a paragraph of text. I am able to select a block of text from the Code Window and drop it onto my VB.NET apps TextBox and complete the text operation. However I am unable to drag and drop the altered text back to the VB Code window Via the DoDragDrop method.
If e.Button = MouseButtons.Left Then Dim d As New DataObject d.SetText(Me.TextBox3.Text) Me.TextBox3.DoDragDrop(d, DragDropEffects.Move) End If
So in my window onLoad method I am pre-populating a grid with values retrieved from a database. Here is the method below for the window load:
Private Sub winMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ''#Load Grid Dim dt As New DataTable With dt
[code].....
What happens is, when I press F5 to debug, the program loads, and the grid is still empty, just as it is without a datasource. When I try to step through the code, it actually reaches down to the line that reads
and then stepping over this line...the window loads and it doesn't go any further in the method. What the line of code above does is eventually make a execution call of some SQL to a SQLite database, and the code gets to the point at which it calls the execute method, but doesn't even make the query yet. All the objects up until that point in the code are set properly as well (found through debugging and checking locals.)Edit:Exception is this:
"Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

Excuse me for posting this, but I have searched both Google along with this forum before asking this question, maybe I'm not using the right keywords but I apologize if it's easy to find.I would like to know how one could close a third-party window (application) if a specified string was found in the window title.
I want my console application to be able to do one function I have when you click one option on the windows context menu, and another function when you click another option.
In a program I'm working on, I want a "Loading..." dialog to close when it can't log in to a site using the username and password provided by the user. Basically, I have the code set up right because the function it is supposed to carry out when that occurs does work, but for some reason it ends up in some really weird stuff happening. In the Loading form, I have it set to do "Form1.Show()" and then "Me.Close()", assuming it would simply show the login form and then close the Loading form. However, when this happens, the Loading form closes, and then for only an instant Form1 shows, and then the Loading form shows and Form1 closes. This happens forever until I stop the debugging, and I can't seem to figure out why. Am I using the wrong method? What exactly does Me.Close() do anyways? All I want to do is close the form and open another
im tryin to make a application that could disable 2 services when when i run the application. so it would change it from say running automatically to disable. i have a lot of computers i have to administer, and i dont feel like goin one by one doing. Nd ima need radio buttons because a few machines are w7 and others r xp nd they each got diffrent services that have to be disabled.
I have a situation where me.close() doesn't close the form. I have a form with a button with the code seen below. What happens when the button is clicked is the new form shows, but the original form(calling form) is still there. When I go into debug mode, I can see the me.close() execute, but nothing happens (calling form stays open). When I close the second form both forms close. If I comment out the call for the second form to open the first form closes without problem.
Private Sub cmdNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdNext.Click Dim f As New frmOrder3
How to catch the event of the window close button(red X button on window right top corner) in wpf form ? We have got the closing event, window unloaded event also, but we want to show a pop up if he clicks the close button of the wpf form.
I have an application with a splash screen which gets shown before the application starts. One of the requirements of the application is to allow users to restart (or atleast clear the form) so that other test cases can be ran. Because there are so many forms and variables, we elected to simply call Application.Restart() to accomplish this.
What we would like to do now is disable the Splash Screen when Application.Restart() is called. That is, only show the Splash Screen when the application is initially started, not when it is restarted.
I would like to have an option to pin the window that contains search results. Currently our application has a search for for instance sales order. Then, when the end user opens a sales order, the search screen is closed, and the sales order is opened for view or edit. However, the users is complaining (with good reason) that they want an option to keep the search window open. Thus, something like a push pin/thumbnail that I can test the state before I open the sale order. If it is pinned, then leave the screen open. If not, close the search screen. I've seen a couple of 3rd party controls like this, but we like to stick to built in/native components only.
