I'm making an Install Manager and when you hit the install button a dialog is suppoed to come up saying that your installing and theres no way to track your installation and some other stuff but it only pops up after all the software is downloaded and while its installing. The finish button is supposed to show up when everything is completed that they checked off. Instead, the dialog pops up after it finishes downloading and while it's installing. It also shows the finish button before it's finished installing. Heres the necessary code
Dialog1.vb
Imports System.Windows.Forms

I have an application (written in VB.net 2008) which reads a text file. Parses the record and uses the second field (a UK postcode) to match an Access database (SQL - Select * from Table1 ......), then writes a text file back out with the original input postcode plus several fields taken from the access database.
I have 3 counts happening during the process, records read, postcodes matched and postcodes not matched. I move these values to labels on the form, then every 50 records read, I refresh the form (me.refresh) to update the labels (showing the end user where the process is upto).When running, if I drag the window around the screen, or minimize then maximize, or click off the window to another window, the application seems to freeze and the counter labels do not refresh.
I have a dialog window that I open from a record in a datagrid, this datagrid happens to be inside a Page that is navigated to inside a frame.
I have a button in this window, that when clicked, I would like to navigate the main window (which happens to be in a frame), to a different page that the datagrid is on.[code]...
I'm opening a new window as a dialog box via code.If I click on another application (let's say outlook) and then click on my project again in the task bar I get my main window and my dialog box is in the background and I can't get it back. What's wrong and how can I fix this?
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).
I am working on an app that is an MDI. When the user clicks a button on an MDI child, I want to "disable" the current MDI child (and only the current child window), open a new window that has control, and then re-enable the child window when the new window is closed...very similar to using showDialog(). The thing I an having trouble figuring out is how to allow the other child windows to be active at the same time as when the new window is open. If I use the showDialog(), all child windows are disabled
I 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:
Once I click a link, I want to popup a dialog/window to display all the information of products. The parent page should be disable while the popup is opened. then, I would like to be able to pass information from the popup to the parent page..
I have a simple html file that i want to send to the printer (to print it) i don't want to view it or anything, i also don't want to use webbrowser control. I also don't want it to show me the printer dialog window (where i chose the printer, preferences etc...) Just a simple send to printer. how can i achieve that? Share your knowledge it's one way to achieve immortality.. [URL]
I have a dialog box that pops up from a webbrowser window when i invoke click.I have copied a filepath to the clipboard but does anyone know how i can do a ctrl + v to paste the text into the dialog filename window.
My Front end is VB.net 2008.I have a form. In this form, I have a menu control, this menu control has four buttons.On clicking the first three buttons, open the window with Show() event. and the fourth button open the screen with ShowDialog().Now, One by one I am clicking the button , so finally i have now four windows of this application.(Three with Show() and one with ShowDialog())Right?
Now I am minimizing all the windows with the help of Window + D Button.After this, If I use the keyboard(Alt+ Tab) keys. This is opening the showDialog window on top because , Show dialog's TopMost = True.Now I come back to my problem. That's why I cannot use the show/Showdialog overloaded menthod to pass the Me/form-id .Again, I use the keyboard(Alt+ Tab) keys, to minimized all windows. In the taskbar and Startmenu properties ,I have selected the Group Similar Taskbar buttons.This resulted in the heap of my application windows, one on the other.Now i click on one of my application window , and If I click the window other then the Show Dialog opened Window, this is not bringing the show dialog window to topMost.
Note:- There is no parent child window requirement. That's why I can't use the Show/Show Dialog overloaded method to pass the Me/Form-id
I've recently just started looking into TCP sockets for Server-Client communications in VB.Net(VS2010); which I have working fine whilst on a single form. However, when I try to load another form it calls the form_load part and runs that part, but then appears as if it's in an endless loop on the original form because the mouse turns to time out whilst on the new form. Client side Login form(works fine and is responsive)
Public Class Login Private client As System.Net.Sockets.TcpClient Private Const BYTES_TO_READ As Integer = 255[code]....
Tried breakpointing to find out where the loop appears to be and I think its in the doRead sub.
I have an application which runs quite good, only once every X minutes it totally freezes, and even when running debug mode from within the VS2005 IDE, Visual studio becomes unresponsive. After pressing the pause-button to see where the app might be stuck, a messagebox saying "Unable to break execution" might pop-up after a minute or two. My app uses some timers, threads, and threadpool calls. So I'm afraid I got a deadlock somewhere, although I can not find it. Is there any way to find out where my app might hang?
Note: I synclocked every routine with a dedicated object, and for queues or arraylists, I even used the synchronized methods to modify them. I don't use recursive routines, so they cannot deadlock themselves. The strange thing (to me) is that all of my app hangs, none of the threads seems to be running, nor background, nor the GUI and even the VS environment.
i have a vb.net application that plots 16 plots immediately, the plots data are realtime. the 16 plots must draw the points at the time they receive them (must be no delay), to do that
1- i made a timer with ticks at 50 ms.
2- at each timer tick call the plotting function 16 times (with a graph name as parameter)like that: [code] it made a big delay, when i used threading the application became unresponsive.
I have a WPF application in which i have to do a long running task (basically reading from network). Just to give you a snapshot I am doing the following thing on button click
Dim t As Task(Of String) = Task.Factory.StartNew(Of String)(Function() 'Thread.sleep is simulating long running task that will make UI unresponsive Thread.Sleep(10000)
[Code].....
I cannot use Event based async methodology because the reading API actually exist in a dll which i refer in my program, that contains a function Public function ReadFromNetwork() as String. This API is making an async call to network to read a long string and return to UI. So, in short i m doing TextBlock1.Text = ExternalDll.ReadFromNetwork().
but the problem is that even if i use Task asynchrony, the UI is still unresponsive.
I'm currently trying to write a football simulator but am having issues with the computer becoming unresponsive. There are long lines of code (several thousand lines) that are executed over and over as one run of the code is equivalent to one second of game time. While the game is setup to be like Football Manager where you watch the game live, there will also be cases where the entire game is simulated without you watching. When doing a full sim of a game, I just have a loop which executes the code block 7200 times (games go for two hour roughly).
At the moment this takes about a minute but even when I get it down to the desired 5-10 seconds or so, I dislike the fact that the computer becomes completely unresponsive during this time. In a round there are 9 games and you'll be simulating without watching 8 of them. You're looking at 1-2 minutes of simulation time or possibly more. I can't have a loading screen that long! How can I program the game so it runs these simulations yet the game still remains responsive? It'd be fine if the user could muck around in the menus and stuff while the simulation runs.
The coding that I have a problem with might make people think that I am creating some malware or something stupid. So the project I am doing is associated with iTunes. iTunes allows people to have one library. There is another way, but it is very confusing to some people, and very unreliable. So my project is that I will allow people to have multiple iTunes libraries on one computer. So the problem is this. In order to have an option to choose your library, I gotta make sure that iTunes is not running. So this is the script:
Code: Private Sub CheckAndCloseiTunes() retry: 'Custom class that includes the function to safely close iTunes
[CODE]...
So when I use the Threading.Thread.Sleep(2000) code, the form becomes unresponsive.

I have a simple desktop application that uses a .NET setup project (.msi file) to perform the installation. On the first installation, everything proceeds in a timely fashion with good feedback for the user.The problem occurs when the user is installing the latest version of the application over an old version on their machine.There is an unacceptably long delay of about 60 to 180 seconds from the time the installer's 'Welcome' dialog [It's not the Welcome dialog, I've removed that from the Start section of the setup project and replaced it with a CheckBox dialog to ask if the user wants a shortcut on the desktop] disappears until the 'Progress' dialog appears. The user sees minute(s) of blank screen and thinks the install has stopped or failed.
In the setup project properties, I've got the 'DetectNewerInstalledVersion' and 'RemovePreviousVersions' properties set to true. So, I believe that while nothing appears to be happening, the installer is actually removing the old version. The 'Progress' dialog does not appear until the new version begins installation.I've been trying to either:
a) Get the 'Progress' dialog to display immediately after the 'Install Icon' dialog disappears
b) Show another dialog while the Uninstall is running to let the user know that the setup is still running and everything is OK.
I have been unsuccessful with both methods. I'm using VS 2008 SP1?
Is there a way to launch a Modeless Dialog that stays active even when a Modal Dialog is launched? Can I put the Modeless Dialog in a seperate Thread or something like that?
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 have an assignment due this week in which I have to make a app that has 5 buttons and a picture box. When each button is clicked it has to show the corresponding picture in the picture box, the fifth button closes the app.
I have the whole form set up the way it should be, but I have no idea how to write the code to make the buttons display the images and close the app.I have the images in a folder within the project folders.
I have yet to be able to find one, the one I found should how to do it using a file opener dialog and a folder browser dialog but that is not what I think my prof wants us to do, as that is more for a picture viewer app that lets the user choose the file of the image they want ot view.
All i want is for the buttons to be linked to specific photos that are part of the application itself and have them open.
Is there a way to launch a Modeless Dialog that stays active even when a Modal Dialog is launched? Can I put the Modeless Dialog in a seperate Thread or something like that?
