I have made a drawing program. It draws a line when you click in the form, but if the form is minimized or another window is on top of it, the lines disappear partially.
Here is the

I have an add-in that creates a form, adds controls to it, then tries to add some more. But on the second attempt to add controls, they disappear. If I have an error in my code that gets displayed in a message box I can see the new controls behind it. When I click OK they disappear. If I have no error and step through the code, they are there according to properties, although I can't see them because the form will not display while in debug mode. When the program finishes, th controls that were created are gone. Perhaps I am selecting the form to edit wrong.Too bad there isn't any documentation (or any than can be found) that describes how to do this.[code]...
View 5 RepliesI experience very strange behaviour of a windows form written in VB.NET 2005.
The form contais DataGridView with data.
I minimize the form to Windows task bar, then I restore it. The form appears, but the DataGridView and other controls are not displayed. In order recover from this situation, I need to resize the form or maximize it.

View 4 RepliesI 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?
View 4 RepliesI 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'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
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[code]...
I have a MainForm which contain SecondaryForm as a control of the MainForm.SecondaryForm contains DataGridView which loads data from sql server and I add a collumn named SUM that SUMs all the values of the same row. This is provided within the LOAD event of the SecondaryForm.When SecondaryForm.Load events finishes, the program goes back to MainForm right after the line "SecondaryForm.Show" and here the values of the column SUM disappear.When i write those values runtime, they never disappear.
View 6 RepliesEvery once in awhile when I double click on a form in design mode (Windows Forms Application) that contains a tab control, all of the controls on the tab control disappear. I have to reopen the form to get them all back. In addition to this, the column order of my columns on any datagrid inside a tab control get rearranged when this happens. Is this a known bug and if so is there a hot fix or patch?

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.
View 6 RepliesI 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]

View 4 RepliesIs 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 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))

Imports System.Runtime.InteropServices

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.

View 2 RepliesI 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.
