Winapi - Closing A Modal Popup?
Dec 15, 2009I want to wait for and close a modal form (a popup) from another application, as soon as it appears. I want to do this from VB.NET, but suggestions in C# should be easily translateable.
I can hard-code the modal popup's caption in my app, since it's long and unique. What I want to do is simulate either the user clicking on the close ("X") button on the form, or a click on the defeault, tab-order 0 button of the form. Either would work.
Maybe I need more info about the modal popup other than the title bar's caption? In any case, it's safe to use it as an unique identifier of that modal form. I also want that code to terminate checking as soon as the first event of closing the popup happens.
I believe it's trivial, but I can't find any ready info on that. Microsoft says I should not send WM_CLOSE to the modal popup, since it will call DestroyWindow() instead of EndDialog(), but to be honest I don't even know what "sending WM_CLOSE" to the "window" means =/
Finding And Closing Modal Dialogs In Code
Aug 21, 2005There may be times when it would be useful for your code to be able to find and close modal dialogs displayed by an application. Perhaps you do not want to have to wait indefinitely for your user's input, or are using the COM Web browser control to automatically navigate Web page and would like to interactively close alert messages that pop up.Digging into our Interop toolbox, we find that this is a relatively simple process using a few core Win32API calls. Starting with the handle of the main window associated with the dialog (this is the form from which the messagebox was shown, whether from your code or from a Web page hosted in a Web browser control on the form), the GetWindow function can be used to retrieve a handle to a dialog windows (called a popup by the Windows API) being displayed (if any). The same function can then be used to enumerate the child windows of the dialog to find a button on the dialog to click in order to close it, and the SendMessage API function can be used to simulate that click, effectlvely closing the dialog window.
NOTE: At the top of whatever code file you put this code, be sure to include the following line (thanks poiygon for pointing this out):Code:Imports System.Runtime.InteropServices this allows for the shortcuts to the DllImport attributes.[code]This sample can be easily modified to close a dialog in another application (by using the MainWindowHandle of that application in the LookForAndCloseIEPopup function, instead of "Me.Handle") or to close any other type of modal dialog message being displayed to your user.
VS 2008 Modal Form Closing Unexpectedly
Dec 18, 2009I have a modal form that does double duty.When a user wants to add a new object to a database, I open the form blank and they fill it out. When the form closes, all of the data is passed back to my main form and is used to create the new object in the database.When a user wants to edit an existing object, I open the form and pre-populate all of the fields with the object's data.I'm running checks on the form as they edit the fields, only enabling the "OK" button (which will update the database) if the form has actually been changed. If they make a change and then undo it, the "OK" button is reset to Enabled = False.At the bottom of the form are a ComboBox, two buttons and a ListBox. The intent is to allow the user to select an item from the ComboBox and "Add" ("Add" button) to the ListBox, or select an item in the ListBox and "Remove" ("Remove" button) it FROM the ListBox.
This function works fine when the form is loaded blank.When the form is loaded with data, however, (and in the testing I've done, the ListBox has no items in it to start, which is valid), adding an item from the ComboBox to the ListBox causes the Modal form to close with a DialogResult of Cancel.I've tried to trace the source of this issue, but stepping through each line in debug mode gives me no clue as to why this is happening.I COULD remove all of the checks and update the form each time the user presses "OK" (in the case of no changes, the database data would be overwritten with the same data), but that seems kludgy and less elegant. Plus, I'd like this logic to work.
DataGridView's RowValidating Event Fires Differently When Closing A Modal Vs NonModal Form
Mar 24, 2011Based on our tests primarily done in VB.NET in VS2010 it seems that when you close a WinForm the "RowValidating" event of the DataGridView on that form behaves differently depending on whether the form is MODAL or NON-MODAL. What we did was open the form (MODAL and NONMODAL) and changed a value of a cell and then immediately clicked the "X" to close the form. It looks like the "RowValidating" event DOESN'T fire if the grid is on a MODAL form but it DOES fire when the grid is on a NON-MODAL form. We can't figure out why that is... Is this a known bug in .NET?

Expect Some Dialog Window To Appear In A Non-modal State?
Apr 19, 2009If I type this code (VB.net 2003):
Dim myDialog As frmTestDialog
myDialog = New frmTestDialog
myDialog.Show()
you'd expect some dialog window to appear in a non-modal state. For some reason, this isn't the case with a program I am working on. Most of the dialogs use ShowDialog() to open them, and one uses Show(). The second I try to show another non-modal dialog, the dialog appears in a modal state. Another strange thing is, before I show the dialog, there is code to shift the dialog location to centre it on the main form - this isn't executed either: the dialog appears at 0,0.
My usual trend is to blame myself for errors (usually the case), then I blame the software; I have checked every single line of code (including the generated code), and it all checks out - the dialog should be non-modal. But ... it's not. I've come across other errors in VB.net 2003; is this another instance?
I'll try creating a new dialog and displaying this non-modal, and see what happens. If it works, I can just transplant the code but this shouldn't be happening, just like if I go to a shop, ask for a cola, I expect a cola not a Chinese panda; more annoying, I return the panda, ask for a cola, and they give me the panda back do loop until I give up The system does using threading, but none of that code connects to the display dialog routines all dialogs are opened with more-or-less the above code (a few have simple validation routines).
MessageBox Not Showing From Modal Dialog Window
Jul 5, 2011I 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:

C# - Calling Modal Window From Asp.net Secure Site Links?
Jan 28, 2011having a modal window spawn for a secure asp.net site. I currently have a asp test site setup which when the user clicks on the login link it opens the standard asp.net login page (login.aspx) within a modal telerik RadWindow. I am calling this page using javascript and this works fine.
The challenge I have now is when a user clicks on a link within the page if that link points to a secure section the login screen loads in the main frame of the site vs. a pop-up. I realize why (aka my js funciton is not being called) my question is to work around this would the correct/acceptible approach be to call a method from each link/button that tests for user authenticaiton? If the user is authenticated then redirect to the page otherwise call the javascript funciton to open the window?
UPDATE: I have some progress to now at least determine if the user is validated. Since I am using forsm auth I can test this using ISAUthenticated
public void LinkButton_Click(object sender, EventArgs e)
{
if (Request.IsAuthenticated == false)
{

Clean Up Memory After Closing Window In Wpf?
Jun 16, 2009I've created an app, which puts windows onto the desktop. When i click on the window it creates a new window and passes the first window's Items collection to the second window's Items collection. Opening the second window adds around 2-4 megs of memory to the app's mem usage. Now if i close the second window, the memory still stays on the same level as when the window was opened. When closing the window, i reset the Items property and clear all images that i'm using in it. It has a wrappanel with some elements, that's also cleared using the .clear function of the wrappanel.children. What else should i do to free up the memory?

View 2 RepliesWindows Form Closing Automatically When Parent Window Gets Focus?
Jan 24, 2012VB Windows form Application.. I am developing an application of which part of the program is around configuration settings allowing the user to enter configuration items. When the menubar item for configuration menu is clicked on the main form the menu opens.This is fine but the mainform should not become active again until the configuration menu has closed. This does not happen right now and the mainform simply comes to the foreground and the configuration form goes to the background... I realize that coding an event on the Child form to handle this would not work because the child window loses control and the main form gains control.. I thought of coding a function as follows on the main form but it does not seem logical because i would have to add to it for everyform and do checking to make sure the child is actually open before trying to close it..

Either change the application to handle windows messages, or use the SendKeys.SendWait method".
