I am using VB.Net 2010. I have two dialog forms open at once. the form that does not have focus I am trying to close and reopen to show the value changes. Below is what I have.
[code]...
the form associated with f never closes, however does open with the new values. I have tried Application.DoEvents and that hasn't worked.
Whenever you have a messagebox, it grabs attention from your main window and doesn't let you click back into your form until you hit okay.I want to make a form that does kind of the same thing. I have this for that shows download progress and I don't want the user to be able to click back into the main form until the download form is finished.
View 4 RepliesI have a borderless form displayed as a progress object. This is displayed via childform.show().
I'm overriding CS_DROPSHADOW to give it the shadow (pictured), when the form loses focus (parent clicked or another formapplication) the shadow is lost.
How can I keep the form focusedselected similar to a modal form? (I cannot use showdialog due this being called from various threads other than UI) Using Me.TopMost = True works, but obviously puts the form above all others rather than just the parent.
I have an about form which I hope it can close by itself if I move the mouse to somewhere else. I try form_lostfocusevent but unfortunately this can NOT be done
View 8 RepliesI have made a little programme where the user can put in a name to search for a contact.The matches then fill a Datagrid and the user can then choose the one they want and the programm then opens the contact form (from outlook client)The Contact form opens ok, and it brings up the correct contact. If the user then selects the option to "Email" from that from I then get the error message"A Dialog is open" etc...
My code is as follows
Sub GetContact()
Dim objOutlook As Outlook.Application
Dim objNS As Outlook.NameSpace
[code]....
It seems to be due to Outlook being open or opening?
I have a form with a "print" toolstrip button. When I click that button I run the code shown below. The print dialog box appears. The title is dark blue seeming to indicate it has focus. The main form is lighter blue indicating it does not have focus. But hovering over the "Print" button (or the cancel button) does not cause it to change color. If you click on the print button, then the color changes and the second click causes the appropriate action. Same with the cancel button. If you click on the dialog label or on the main form the only thing that happens is the print button will then become "active" and a click there then works. If you click on the main form once, nothing happens, but if you click on it a second time you get the "bonk" sound indicating you ae clicking on the wron modal. As if this isn't strange enough, this action just started recently. I made a few unrelated (as far as I can tell) changes, and discovered this action.[code]....
View 15 RepliesI'm developing a WinForms app in VB.NET, that handles sets of style data, and when the user clicks on another set's label, it prompts through a dialog "You are leaving this style preset to edit another one. keep changes on this one? [Yes] [No]".But, I'm facing the problem that, when the user clicks either option, and the dialog closes, everything has to be refreshed, and loading the form again seems a good option.[code]But as soon as that sub is called from the prompt, it crashes the application. (doesn't show an error in debug, simply crashes) How should I, from a given dialog, close the dialog, it's parent, and re-open it's parent? (which triggers all the Dialog_Load() code of the parent)
View 2 RepliesI have a main form that has a button with which a smaller form is shown. Think of the smaller form as the Find/Replace dialog in many applications, such as Notepad. It's important that the form is (what I believe is called) modal. What I mean is that it always stays on top of the main form. I ensure that by calling the Show method with "Me" as the owner argument. Whenever the small form loses focus it will not disappear into the background but stay visible (albeit out of focus). If you don't understand open up Notepad and have a look at the behavior of the Find/Replace dialog.
Here's my problem: instead of actually closing the form when the X is pressed, I want it to simply Hide itself, so its position and the state of any controls (checkboxes etc) is preserved automatically.To achieve this I simply cancel the FormClosing event and Hide it:
vb.net
Private Sub Form2_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
[code]....
To show the form, I use the following (note the (Me) to make the main form the owner of the form; this ensures that it remains visible even when it is out of focus):
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Form2.Show(Me)
End Sub
Now. When I run my project, and open the Form2 (small form), then hide it again (by 'closing' it), I can no longer close the main form (Form1)! It seems the main form cannot close when the small form still exists (albeit invisible)...?? When I don't use the Me argument in the Show method, I don't get the behavior I want. I know I can set the TopMost property to True but that will also cause it to become visible on top of all the other forms, even windows not part of my application.
In form I have one button which has functionality to pick up some data from (by mouse click) Parent application.
I have handle for parent application handle, but even if i tried to bring it on top i am not able to do selection because form is modal.
Requirement here is open modeless dialog and wait till it close. other wise it goes further and executes functionality below.
Another option can be open form as modal and at runtime change it to modaless.
How would i go about closing my openfiledialog in the event that there is an error[code]...
View 12 RepliesI have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.
I often use the process of displaying a dialog from a form, with the dialog user input then used to update the main form without any problem. In a new scenerio I launch the main application screen, I then show a login dialog ontop of the main app screen and can launch another dialog from the login if a new user is required. The plan is to update the login dialog (updating a combobox to reflect the addition of a new user) from the new user dialog.
See code below :-
'Update login forms user list as new user added successfully
frmRoomBookingLogin.cboLogin.DataSource = Nothing
frmRoomBookingLogin.txtPassword.Text = "Updating password from dialog"
MessageBox.Show("The password text is " & frmRoomBookingLogin.txtPassword.Text)
[code]....
The messagebox implies the dialog has been updated yet the text does not change. Is it possible to update the dialog when using a setup such as Form -> dialog -> dialog? I'm intrigued as why the dialog does not reflect changes. I have never refreshed/repainted the dialog as never required to in my other examples when updating a form from a dialog and never encountered a problem when using a two tier form setup.
I actually have gotten the events firing like I expect except for trying to close the dialog window.
Background: I have a wrapper around my "Jabber Client" that sets the delegates for the client wrapper and basically generates a messageProcess event. This event is wired in the main program Class[code]...
I've built a dialogbox with a RichTextBox and I'd like to have the following behaviour:
I've got the focus (cursor) in the RichTextBox. When the ENTER key is pressed, then there should be a new line in the rich edit control created. The ENTER should NOT close the dialog box [as it does now :-( ].
Whenever I try, the save file dialog comes up when I hit No and same when I hit Cancel....
If My.Settings.SaveSTS = False Then

If MsgBoxResult.Yes Then
If My.Settings.OnceSaved = True Then
Dim writer As New IO.StreamWriter(SaveName)

A Dialog that is added to a Windows Forms project comes with two buttons (OK and Cancel) and Click event subroutines for each. The subroutines close the Dialog with different DialogResult enumerations. Here's the code in the one for Cancel: Me.DialogResult = System.Windows.Forms.DialogResult.Cancel Me.Close() But either statement (changing DialogResult to an enumeration other than Null or Close), by itself, will close the Dialog as well. (Try commenting out one and then the other to prove it to yourself.) Here's the question: Why both? Why not just one or the other?
View 1 RepliesI have set up a notify icon for my form. I want to make it so that when the user clicks the close button that it doesn't close the form it just takes it to shows the notify icon. They can exit the program from the notify icon. Can someone tell me how to keep it running?

View 1 RepliesI 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.

View 21 RepliesI'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.
View 2 RepliesI'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.
I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.
My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.
In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.
I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.
Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox form ):
CODE:
I want to be able to check if there is currently a dialog or modal form shown for my form so that I can close it.
Is there a way to do this?

Set the form's visible property to false before calling Show. Error Number 5"

My project has a single dataset with about 6 datatables. Each of those datatables has a TableAdapater and a Bindingsource on the main form (due to various databound controls).
Now, I want to have a second form for adding a new record. If I bind the controls to the datasource it creates new TableAdapaters and new Bindingsources on that form. I was wondering if it's possible to simply use the ones from the main form instead like this
