The Form that I'm trying to get to Display as a Dialog box is AddNewStudent1 but I keep getting an error that says AddNewStudent1 is not defined.
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.

View 6 RepliesI have a DataGridView with a single column that currently displays a short list of items. When the user clicks a button to run an update, each row/cell is read and processing begins. I would like to have the selection idicator move down the rows in the DataGridView as it completes processing of each record. How can I display the iteration of the DataGridView rows while the processing is underway? A redraw of the DataGridView or something.This is a VB.net windows form, I know how to do this with AJAX I think, but how can I in a Windows form?
View 1 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 ):

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

How can i create a form dialog. I mean when that form show, then i click to other form, form dialog still show and behave like a dialog.( when lost focus , dialog alway focus).
View 2 RepliesWhenever 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.

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.
I 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.
At one point I have a dialog form open, but in order to process it, the user might want to access information on other (open) forms. This would necessitate the ability to move/resize/scroll the other forms, but obviously everything is frozen during the dialog. I don't suppose it's possible to achieve this "semi-modal" state, where other forms can be browsed, but no other actions taken?

View 1 RepliesIn a dialog form I've two date pickers, Date1 and Date2. At load I set the two dates to:
Me.Date1.Value = DateTime.Now.AddDays(-90)
Me.Date2.Value = DateTime.Today
And the sql filter is set to:
Where shipDate BETWEEN '" & Me.Date1.Value & "' and '" & Me.Date2.Value & "'
When I execute the project the two dates are shown fine but if I change Date1 to say 01/03/2010 (European format) and leave Date2 as per defect, the range of data returned is missing the information from 01/03/2010, meaning the data starts painting from 02/03/2010. If I select 28/02/2010 for Date1 then the returned data is from 01/03/2010 to Date2. Somehow, one day is subtracted from Date1. If I comment out Date1, then 01/03/2010 is recognized. What is wrong with Me.Date1.Value = DateTime.Now.AddDays(-90)?

View 13 RepliesI'm having trouble with MDI child and a dialog form. The problem details are listed below:
1. One MDI Parent form (Form1) with a button on it (Button1).
2. One Child form of Form1 (name = Form2) with a button (Button2) and a textbox (text_box1).
3. Another form in the project (not child of Form1 and not MDI Parent) with name Form3. This form has also a button on it (Button3).
The application behaviour is as follows: the application starts with Form1. Clicking the Button1 will show Form2. Form2 correctly opened as a MDI child. Clicking the Button2 on the Form2 will show Form3 as dialog (Form3.ShowDialog() ). Clicking the Button3 on the Form3 need to do the magical thing - to set/change the text in the Form2's text_box1.
Tried various examples from this forum. Also followed a lot of examples from net. Nothing works. Tried to create a writable property in the Form2 class but calling it from the Form3 does nothing.
I tried to access the MDIchildren(ss) while ss loops in MDIchildrens array but I don't know how to access the label control inside the Form2 using this technique. Successfully changed the Form2 caption but no controls are available in VB intellisense - practically correct because VB don't know which form from array I'm referring to.

I'm developing an application that should run on a 'kind of' mobile device. It's not exactly a mobile device (hence I'm not developing in the mobile framework, just winforms), but I can't use various Forms either.
Right now I am working on a proof of concept, and I simulated the mobile device simply with a UserControl that has a fixed size. Everything needs to happen on that UserControl, and I cannot display any other forms.
However, I now need a 'Dialog Form' to let the user enter some data (mainly text but it doesn't really matter). What I'm doing now is simply showing a Panel with a TextBox, OK button and Cancel button. I bring that panel to the front, hiding the rest of the application, when required. The different Panels (there's also one for a CheckBox, ComboBox, and the main application is also on a Panel) are all on a 'PanelContainer' UserControl I made, and I can switch panels simply by specifying their 'key' (a string such as "TEXT", "CHECK", "COMBO" etc). So I can display the textbox panel by simply doing
panelContainer1.SelectedKey = "TEXT" That brings the textbox panel to the front.
What I want now is that I can 'show' the panel as if it were a Dialog form. That means that the code 'waits' until the user has entered his text and either clicked OK or Cancel. Then I could use it like this
' Show the panel here
Dim result As DialogResult = panelContainer1.Panels("TEXT").ShowDialog()
' and immediately use the result (the code won't come here until the user has selected ok or cancel)
