Don't Show Any Dialog, Or Detect The Dialog Using The Dll Name
Jun 3, 2009
I'm using a DLL in vb.net 2005, and this dll show a messagebox with OK option. I would like to close this Messagebox by code.
I was investigating to use SetWindowsHookEx, but I can not detect it. Is it possible to don't show any dialog, or detect the dialog using the dll name?
I have some code that loops in the background of a form and triggers action if the form is active (this is in a mdi forms application). I use the following to check this:
vb.net
Dim frmActive As Form frmActive = Me.MdiParent.ActiveMdiChild If frmActive.Name = Me.Name Then 'Do work End if
The problem comes when that form starts another form running in dialog mode i.e. form.showdialog. I need the above code not to run while this is the case, but it still returns true when the dialog form is active and the other form is in the background.
Is there any way to detect whether a dialog is open in an mdi environment?
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?
I have a Dialog that is basically a confirmation dialog on some SQL statements. After the dialog I have an if statement: If frmRelease.ShowDialog() <> Windows.Forms.DialogResult.Cancel then.My buttons are set as DialogResult = OK and DialogResult = Cancel respectively on the dialog form.
For some reason, sometimes my button set to DialogResult = OK is returning me a DialogResult.Cancel, and causing me to skip a block of cleanup code.
After deploying and installing my application I use the app to create and save a file with my own file extension. After the file is created I right-click on the file and select Open With.. so that I can associate this file extension with my application. In the Open With dialog I use the Browse button to find my application and select it. In the Open With dialog the application icon is shown, but the name of the app is blank (looks like an empty string). Can anyone tell me why this might be happening? I've looked at the Registry, which shows the correct app, but every time I open the Open With dialog only the application icon is displayed, no name.
<script type="text/javascript"> function ShowAlert(id) { alert('I am here' + id);[code].....
In my gridviews item template for my edit button I have the following to call the function. Which works to show an alert but can't get it to show the dialog? Is it because possibly the postback happening on the grid causing it to close?
I have to create a Dialog box to get the user's selection. I can use the InputBox to get text but if it is able to show a Dialog Box with a Combobox, user can easily select items.
Actually i'm trying to show and dialog into a parent form, An reference example is:[code]Form that is not a top-level form cannot be displayed as a modal dialog box. Remove the form from any parent form before calling showDialog.
I have a dialog which opens another dialog. The problem is that the second dialog opens behind the first. Is there a way to stop this from happening? I tried bringtofront with no success.
i have form1 and form splash..i used the splash as processing indicator i place gif in the splash form...and in form1 i call the splash in separate thread..
like this..
Dim splashthread As Thread = New Thread(New ThreadStart(AddressOf SplashScreen.ShowSplashScreen)) splashthread.IsBackground = True splashthread.Start()
[code]....
now,my problem is when form1 is loaded and click button process in it..the splash form will not display modally...is it because i called the splash in separate thread?..
I'm trying to create a program that will look at a website and check it for updates, similar to an RSS feed. It then will show a dialog (Form2) that will inform the user that there is an update.Form1 is used as the configuration form and is able to be shown via a notify icon in the system tray, which is on Form1.Originally I would have Form1 hidden via Me.Hide() and then run a timer which would check for the updates and call Form2.ShowDialog() when there's an update, I found out however, that if Form1 is hidden, the dialog will not show.
Next I tried not Hiding the form, but instead setting its ShowinTaskbar property to False. At this point the program functions correctly, however when I minimize Form1 it sits in a shrunken window near the task bar... Is there any way to completely hide Form1 (when minimized), and allow Form2 to be shown as a dialog?
I designed a application on vb.net 2005. Some of the forms in this application has databindings controls. Now when such forms loads it takes some time. I want a splash screen containg "Please wait" message to appear till the form loads and the wait splash screen would be shown for every several forms in the application not only before the start up form.
I need to open a page as a Modal Dialog using Jquery .For Example: I have 2 pages say, Parent.aspx & Child.aspx, I need to open child.aspx in a modal dialog using JQuery when i click on a button/link in the parent.aspx. Also Postback can happen in the parent and child pages.
I've created simple modeless dialog box that show a progress bar, plus an ok button. It works, except that the "OK" button doesn't display until the progress bar is filled. My dialog is name frmProgress and I'm using:
MDIform contains Form1. Form1's MDIParent is set to MDIform Form1 has a button on click that opens Form2 as a show dialog. I need this Action.Form2 has another button that opens Form3.Is there anyway that I can make Form3's mdiparent the original MDIform by passing Form1.mdiparent value to form2 (without actually setting that value) that then passes it to form3?
I have a client, who is running Windows 2008 Server 64 bit. He is running our software, it has a built in crystal report viewer functionality. The print dialogue just wouldn't work no matter what. It worked on our 32 bit box and we verified it. I verified it on our 64 bit box, and the print dialogue didn't open either. I did some research online. And one suggestion is to set m_printDlg.UseEXDialog = True. I tried that, but that did not work either...
Here is the code snippet. #Region " Methods " Public Overrides Sub PrintReport() ' NOTE: Do not use bug in reportviewer 'MyBase.PrintReport() Dim objRpt As ReportDocument = CType(Me.ReportSource, ReportDocument) [Code] .....

Share your knowledge it's one way to achieve immortality.. [URL]
I am using Process.Start(fileName) to let Windows open certain files outside of my application with their 'default application'.If "fileName" for example is a ".txt" file, it opens the file in Notepad. If it is a folder, it opens windows explorer with that folder selected.This all seems to work well, except when the user enters a file that has no application 'linked' to it.(a file that has no file associations)I have wrapped the Process. Start() in a Try/Catch block so that any errors are caught and displayed.When I now open a file without any file associations (windows does not know with which application to open it) it tells me that it cannot find any application to open it with. (The exact error is in dutch so I don't think that's going to be much help here, but I think it's clear what's happening, no?)What I would like to happen in this case is that the windows "Open With" dialog comes up, asking the user to select an application to open the file with. Now it just displays the error message and continues, making it impossible for the user to open the file unless he browses to the file manually and sets up the file association, something many users probably don't know how to do.
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 have some shared code I need to use both in a WinForm and a service. How can I test if my code is running in a service, so I can avoid problems with modal dialogs.
I know that with some of the programs I use, when you click on an item to change it's color, the color dialog will actually show the current color and it's rgb value.
I'd like to do that in my application but can't find the answer on how you do it.
To change the backcolor on a textbox, the user double clicks the box and it shows the color dialog.
I think I have all the properties set right -- fully open to show custom colors etc.
As a continuation of my previous posting, which we were able to resolve, I am running into the same problem again, due to being unable to use frmForm1.Show().In my last situation I had to use frmForm1.ShowDialog(), which worked in that case, as it called another form, for example frmForm2.However, now I have a program that is sometimes required to recal frmForm1, and I get the following message: �Close the form before calling ShowDialog.But, in frmForm1,I include, Me.Hide() and Me.Close(). Also, before recalling frmForm1, from a procedure under Main(), I have added the following
frmForm1.Close()
To me that would suggest the form is closed, dead and buried, but the programme still stops at the point of:
frmForm1.ShowDialog()
With the same message: �Close the form before calling ShowDialog.
