Inter-form Communication - Form Being Called Form Several Forms Using ShowDialog()

Mar 28, 2011

I have a form being called form several forms using ShowDialog().

1. Is there a way for called form to know which form called it by receiving a code or key from the calling form?

2. The calling form has a gridview. How can the called form pick up a column's value from the currently highlighted row in gridview in the calling form?

Calling Showdialog() On A Form - From The Main Form's OnLoad Event Makes The Modal Dialog Go Away After A Few Seconds?

Aug 7, 2009

I'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 ):

File To Open As Mdi Child Form / Save From Child Form

Nov 17, 2011

I have a MenuStrip with File > New, Open, Save, Exit located in a parent form, and a RichTextBox located in a child form.The problem I'm running into is concerned with the destination of the file elected from "Open" and the save.When a user selects their file from "Open", I need it to open the child form and put the text into the RichTextBox.I also need the program to be able to "Save" from a child form, whether it's been brought up via "New" or "Open".

.net - Form.ShowDialog() Does Not Show Form?

Apr 20, 2010

I've come across a situation where I try to run a simple line of code in a method Dim res As DialogResult = frmOptions.ShowDialog()but nothing happens. The dialog box will not appear. If I run this method from another location in the code it executes fine (i.e. displays the form in dialog mode and code executes fine thereafter). Hence, it may be the way in which I arrive at this code that is causing my problem, but I cannot see to find what is wrong.

When I pause the debugger the line of code is highlighted in green but I can't see to step over it or into it what may cause this to happen, or what I should be looking for that might be causing the problem??

Form In A Form - Manipulate The App's Properties Place Inside Child Form?

The following code does create a form within a form and does place NotePad inside the child form. You have to manually start NotePad prior to execution (I work on that later) but the code does workŠ My problem is now I want to manipulate the properties of notepad i.e. focus, size, location, etc. but I cannot figure out how to reference notepad and its properties.

Form ShowDialog Disappears

Feb 24, 2009

I have a form that I am using to search for records in a dataset, it has a text box for entry of the search criteria and a 'Search' button to initiate the editing of the entry and .Filter on the BindingSource. This is one form in a project with many, when I show it using .ShowDialog it always disappears, (not visible and not loaded) after the 'Search' button is clicked, I have stepped through and there is no .Hide or .Close that it encounters, it performs all of the logic correctly but control is returned to the main form it was shown from. When I use the .Show method, I do not have this problem.

ShowDialog Form Not Ending

Nov 4, 2010

I converted this app from VB6. I have 2 forms. Form1 instantiates Form2 via a Menu Item.I am having trouble getting Form2 to end when clicking close (X). If Form2 is 'idle' it closes fine; but if I am in a loop processing anything all the events fire, but it continues processing in Form2. I've tried messing with Dispose, Close, Application.Exit, Application.ExitThread. My last attempt was creating my own event to fire back to Form1 and dispose Form2 -- and it hits it but Form2 is still running. What is the deal? BTW if I use just Show vs ShowDialog -- Form2 just blinks and disappears.[code]

.net - How To Wait For Form To Close Without ShowDialog()

May 9, 2012

In my program I use WebBrowser control for OAuth. It's located on vk_auth_window form. So in the code I call vk_auth_window.WebBrowser1.Navigate(vkauthurl). If authentication is successful, I silently get token, but if user is not authenticated a form vk_auth_window is showed to them to enter username and password. To check this I catch _DocumentComplete event and check for the right URL. I need no other code being executed until the user finished authentication or closed authentication form. ShowDialog() does the trick, but it somehow hides cursor from username and password fields in WebBrowser control. So I introduced a variable Dim showform as Boolean=True in and set it to False from the _DocumenComplete event and in the main code I use infinite loop.

While showform
System.Threading.Thread.Sleep(100)
Application.DoEvents()
End While

However it makes userinput slow due to thread sleeps. And If i remove them, it loads CPU quite a lot. Is there a better way to wait for form to close? What is it?

.net - Shared Form.ShowDialog Method?

Apr 18, 2011

I have a new developer that is calling Showdialog (in VB.NET) on a Windows Forms form without first creating an instance of the form.How is this possible? I don't see a shared method for ShowDialog...

I'm not crazy about this approach either as it seems to me that the dialog will not be disposed until the application exits.What am I missing? Is this a new best practice?OK, Form2 is just a blank form.Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object,

ByVal e As System.EventArgs) Handles Button1.Click
Form2.ShowDialog()

Block Like ShowDialog Blocks But Without A Form?

Sep 10, 2010

So you know how when you call "Form.ShowDialog" from where ever you call it, it blocks until the form being displayed closes. And then the function returns whatever result it was.I want to know how to block like, but without a form, yet still have the "main ui thread".Basically I have this long process that needs to thread out and do several things... and it's heavily event based. It jumps between two threads, the main ui thread, and it's own background thread. The main ui thread needs to have access so that I can randomly open different dialog boxes for things... sometimes they're just windows asking to hit OK or Cancel to continue, others it's to perform some action, etc etc.

But there is NO central form related to it. It's a complete background thread running that randomly hops over to the main ui thread for things.Right now I have this class I designed called lets say "DoJobProcessor". On it is a function called "BeginDoJob" that threads off from the thread pool... when ever I need to jump back I use a ManualResetEvent to block on the background thread, jump over to to the main thread with "invoke" and passing a reference to the MRE, then release the block when done there and continue on on this background thread.

All while this is going on I just set the form I'm trying to block the main ui thread from managing by just setting its Enabled property false.It all feels just messy and annoying... and I was just writing something using ShowDialog and I was like... HEY, what if I could block this BeginDoJob method, hi-jack the main ui thread, then let that function return the result when done instead of having this "Complete" event with the return value in it. It's obviously possible because ShowDialog does it, but I don't know how.

This way the job I'm performing isn't always waiting for the main ui thread, instead its the other way around... the ui thread waiting for it, the way it aught to be. Show something, branch off do some stuff and just idle the display while it does it, come back show something else, branch off and just idle while it does that.

I am writing an application in VB2008 with several forms. From Form1 I open a new form with me.hide() and then form2.showdialog(). The system works but in form2 the application runs without screendisplay until the program waits for a user input. So first all databases are processed. Meanwhile no screen is visible for the user. Sometimes this takes about 5 seconds. I would like the user to see the build up screen directly.

Feb 11, 2011

I want to open a form as modal without using showdialog()Problem with showdialog() is we can not open the form as mdi child with it. i want to open few forms as modal but as mdi child forms. but i want to make sure user cannot go anywhere else without closing thst form.if we set parent form enabled = false then i can not set it as mdi child otherwise that form also becomes enabled=false.

if we write showdialog() then so many form icons will appear on taskbar. it we open as mdi child then only one icon appear i don't want to appear so many icons on taskbar so i want to open as mdi child but as modal

from mainform open formA = as mdi child of main form (but modal)
from formA open formB as child (modal)
from formB open formC as child (modal). if i use showdialog() then so many form icons on taskbar.

Interface And Graphics :: Adding A A Form As A Child Form To A Third Part Window

Mar 24, 2011

As Autodesk is going to discontinue VBA for their Inventor product in the near future I have been looking at other ways to run VB.NET in Inventor. To date it doesn't look like VSTA will be the replacement. Automation from an External VB.NET app is certainly possible, but leaves something to be desired for speed and integration. Compiled Add Ins are the Cadillac of choice but can be a royal pain to debug and develop. Autodesk now provides a lightweight VB.NET script interface called iLogic. It's main purpose is to allow extreme customization of Solid Modeling parts. The code actually resides inside the Part Model file.

I have a VB. Net App where I want the user to open a modeless form which contains reference information about items in a select box. If the user double clicks the item selected in the list box a modal form is opened to edit the item.I want the previously opened reference form to remain active/enabled, that is, I want the user to be able to click on it, move it, etc.I was able to get the form to at least show up on the task bar by setting it's "ShowInTaskBar" property to true, however, when it comes to the front the user can still not move it to the side to view all of the Edit Forms information.
