Forms :: Prevent A Form From Being Minimized?
Sep 12, 2011
I've got this little 'Sticky Notes' type of application and the form I have is a borderless, taskbarless form and for Windows 2000 compatability I'm using VS 2008 and targeting the 2.0 framework. One of the hurdles I have is that in XP, Vista & 7 when you click the Show Desktop button all of my note's windows get minimized and without a taskbar icon, it's not easy to get them back (at least not for a normal user) & I'm looking for a way to either right after the windows minimize I just have them all show again or if I can skip the minimizing message in the wndproc altogether that'd be great.
I've put together a test app that'll show the messages in a listbox for the form, but I'm not sure how to go about skipping sending the message to the form's base class. Here's a snippet, listMessages is the listbox on the form:
Private Const WmSize As Integer = 5
Private Const SizeRestored As Integer = 0
Private Const SizeMinimized As Integer = 1

In the main form the user can choose to download information from a device.Since this request takes time, when "download information" is pressed I open new form in a separate thread: Private Sub RunDownload()

I have created an app which has a timer control which, when activated and meets a certain criteria, launches a second form with an alert for the user to review and action. this works just fine. Except.... when the main app is minimised and has lost focus, instead of launching the second form to a normal windows state it opens and sits in a minimized state itself and just flashes. How can I get the the second form to restore to a normal windows state?I have tried form2.focus and tried the windowsstate=normal etc but I'm still barking up the wrong tree.

I have made a project on Library management system using Microsoft Visual Studio 2008 and Sql server 2005 .I have used MDiParent form in this project, from where I can click on the menu item to open the desired form.
I am now able to open the child forms in the main window background.Now what happens is When I click on one menu Item it open in the parent form background.I am able to open all child forms corresponding to the click event in the MenuToolStrip ...all in the Parent form Now the problem is that I cannot minimize child forms when I minimize Parent form..I want child forms also to minimize along with the Parent form.. Also are child forms still not attached to the parent Form is also my question here.....

I have an issue in a project trying to auto-scroll down a ListView (used as Details with columns) when adding a new ListViewItem when the window is minimized. I guess we have to use TopItem property to set force the listview to scroll down.I get two exceptions when the form is minimized: "Object reference not set to an instance of an object." "Index (zero based) must be greater than or equal to zero and less than the size of the argument list."
I'm just using standard .Net components (Events/Delegate) with standard way to use them.
I made a small test code to isolate the issue:

I have small application which shows an alert in every 45 mins....( to take a break from work :) )..... It is a normal windows form with a timer in it and in every 45 mins I am invoking a message box. I am able to make it work but the problem is that when the application is minimized, the message box is not popping up, it stays with in the parent form (minimized). How can I bring it up to the user focus?

I have a 2nd form that is minimized to the taskbar, I can click on the tab and the form opens and shows all of the data fine, but
From the main form, I am maximizing the second form and trying to pass a value to a toolstrip textbox on the second form then press a button on the toolstrip from the second form, I can get this to work fine, but where I am having a problem is
The button searches through a treeview, when I step through my code, I can see the value that I am passing, my code does execute, but the treeview is showing no nodes(but they are really there). At the begining of the code, I put a message box to give me a count of the nodes in the treeview, it shows 0, but I can see all 10000+ nodes. What the textbox is on the toolstrip is a search box. When the form is maximized, I can enter whatever and it finds it with no problems, but if I pass a value it doesnt find anything because the treeview is saying there are no nodes when there is.

I was wondering if it is possible to perform a "mouse"-click without being in the form, like I got this program clicking on certain locations and I would like to use the computer to other stuff in the same time but the mouse keeps going to the location on the screen. I need way to perform a click without using the mouse cursor.

I am in the process of creating an all-in-one application for my own purposes. This application has panels with different "Mini-apps" inside of each. Timer, Notepad, Calculator, etc... The top of the application is a drop down menu and each of the drop downs has "Minimize" and "Maximize" for the appropriate application. When the minimize function for a "mini-app" is clicked, then that application is not visible. When maximize is clicked, the the application reappears.What I am attempting to accomplish is that when, for example, the two lower panels are minimized then the form resizes to only show the top two application.Basically, its like rows. If the two bottom are not visible, then the application should resize to fit nicer. An example of this type of application would be Windows Calculator (found in Windows 7 systems and probably other OS).[code]

I want to use e.KeyCode while form is minimized, I'm working on a screenshot-taker if you know what I mean. So Form1 is minimized > User presses F9 (Let's say the key is F9) > An event happens.

Is there a way to control the size of a minimized MDI form. When I minimize a child form, it apprears at the bottom with the form buttons (minimize, restore and maximize) and just about 2 or 3 characters of the Title Text. I would like to have more of the title text showing so the user can figure out what window he wants to restore if he has a couple of them minimized. If not that, is there a way to have a "tooltip" popup when I move the mouse over the minimized form.

I have made a small program that reads the input of a joystick/GamePad and passes it on to a serial port. It works great I can see all the buttons pressed ect ( in a textbox). But When I minimize the form and press some buttons they are no longer passed on to the serial port and not shown into the textbox?

I have an application with a DataGridView and WebBrowser controls. In the DataGridView I load a DataTable using BindingSource. DataTable is just a list of URLs. I use SelectionChanged event on the DataGridView to load a selected URL in the WebBrowser control. The problem I have is that when I minimize form to the tray, it for some reason triggers SelectionChange event multiple times. What's really weird is that if I minimize to the taskbar SelectionChange event doesn't get triggered. It also doesn't get triggered if I load URLs directly to the DataGridView. What triggers SelectionChange and how to get rid of it?
Public Class Form1
Dim URLTable As DataTable = New DataTable("URLs")
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim URLColumn As DataColumn = URLTable.Columns.Add("URL", GetType(String))

I have designed a windows form(to act as a messagebox) with Label and OK, Cancel buttons. I'm on form1 and call this messagebox form in the closing event. If I debug the showdialog of the messagebox form the custom text is displayed on the Label, however if the application is minimized and when i right click on the application in taskbar and select close window then the messagebox form is poped up however the label doesn't show the custom text.

I have a lot of forms that get placed in specific locations at run time. I need to disable relocating these forms, but I would like to keep the borders and titlebar.
I have tried jmc's codebank submission called "immobilise" but did not work for me, forms were still draggable (could be my mis_use, but no errors were thrown)If this isn't doable, is there a way to hide only the titlebar, but maintain the 3D blue borders all around?

I am making a webbrowser,how to prevent my browser from opening new IE windows. Because what happens is, there are some links that will open new windows and therefore IE comes in place because it is set as default windows browser which I really don't want because my browser looks really bad if it opens links in another webbrowser.I want it to be just a basic browser, it has only one window, and it should navigate within that window. This is because the browser is integrated in a bigger application only for some website applications that are related to this main application.I am using VB.net 2008 Express Edition?

I have a main form called frmMain from which all other forms and actions are launched. In the menu bar on frmMain there is a text box where the user can enter an inventory item number. This shows a new instance of frmBundleSearch. This frmBundleSearch may get multiple new instances opened at a time. What I would like to see is the frmMain in the taskbar separate from the frmBundleSearch when it has enough open instances to begin stacking in the taskbar. Right now, when I debug, when the taskbar starts stacking the application's forms, all of them are in the same stack, so right-click and "Close All" nukes the whole app. Is it possible to keep them separated?
