Force Prompt For Windows Login On WinForms Startup?
Dec 9, 2008
Is there a way to force the Windows Login prompt, just like in web applications, in the startup of a WinForms application (see attached image)?I'm creating a WinForms app that is going to use NT Authentication, but some machines in the company are shared, and logged in with a common login account.I don't want my app to run under the Identity of the common login account. Rather,I want to use Impersonation and prompt for the user to enter their actual domain account name and password.Googling for this in the context of a WinForms application has produces curiously useless results so far.
I am writing a Windows Service that will shut the machines down in my domain at 6:00 PM every night. I just want to do an If/Then statement to see if someone is logged into the machine before I shut them down. For example: If Machine_Is_Logged_In = True Then
Do Nothing Else Shut Down The Machine I've been searching for the syntax but can't find it. I've tried both "isauthenticated" and "my.user.name = "" " but nether of these work.
Is it possible to force a combobox to run it's validation event without moving the focus out of the ComboBox?
I need the event (or an event) to trigger when an item is selected with the mouse or an entry is typed into the combo box. I tried using SelectedValueChanged and SelectedIndexChanged however, these events do not fire if the user types a value that does not exist in the list source. I know I can change the DropDownStyle to DropDownList however, I still want the users to be able to type entries in the combobox (with auto complete).
I can hide my startup form (or make it appear hidden) on startup. I can start my app on windows startup--through registry values--if the user checks a checkbox.
But if the app starts up on windows startup, I want the form to be hidden, so the program can just keep working without bothering anyone. If it starts up because the user started it, I want the form to be showing, because the user probably wants to change some settings or something.
For my VB.NET application, I'm using the windows installer that came with Visual Studio. I can successfully install and run my program on any computer in our office except for one. On this particular machine, my program will stall for about 30 seconds before being able to load the main form. When I start up the task manager, the CPU is hovering at about 0 to 1%, so its not really doing anything but freezing up. It will eventually load, but it really shouldnt take this long, especially when it loads instantly on other computers. Now this machine is windows xp with serverice pack 3 and .net 3.5 sp1.
I have deployed a Visual Studio executible module written in VB Net 3.5 SP 1 with Crystal Reports. When the user tries to view a report(s)they are prompted to login in to the data base that has been data sourced into the report module. The correct database was verified before the build was made. The developer is able to run the report in a run mode on the local machine where the VB project was created. In the properties section in the project the following check boxes pertaining to reports were checked on:
Crystal Reports Basic for Visual Studio 2008(x86, x64) Microsoft Visual Studio 2008 Report Viewer
Notes: If the executible module is deployed to a machine that has Visual Studio 2008 installed, the Reports run fine without a database login prompt.If the executible module is deployed to a machine that does not have Visual Studio 2008 installed, the user is prompted for a login. The data base is a SQL server 2008 database.
I'm creating an app, with a splashscreen, loginform (just enter a name) and a mainform.With I use my.settings. Now here comes the issue I run into.The splashscreen should check (onload) if the my.settings.user contains any info, if it does, the mainform should be shown, if not the loginform should be shown. On my app settings I have splashscreen set to the splashscreen and the first form is set to login form.
basically i want to create a login to my program which uses the same username and password as windows login.I already know how to retrieve username and auto place it in the username box using
TextBox1.Text = Environment.UserName.ToString
i wondered is there an easy way to only allow access if the password matches up to their logon? i dont know about setting up databases but i dont think this option would work because each member of staff can personally choose their password.
I've created an application using VB.net windows application, but now i want to invoke it only from command prompt by giving inputs and outputs. How can i give inputs and get outputs to windows application in command-prompt.My windows application takes file as input and it process and makes a output file specified by the user. I've used 2-forms, in which one reads the input and other is used for the output.
I've successfully saved video files into SQL server as varbinary. Now, my problem is, how can I play those videos in Windows Media Player (embedded in my Windows Forms).
The application I'm developing does some file management chores, such as renaming and deletion of files. I have noticed that often after a file is deleted via code, it is still shown in Windows Explorer although it doesn't exist anymore. A refresh (F5) solves this, however I wouldn't want end users to have to press F5 every couple of minutes when using the application.
Can a refresh of all open Windows Explorer windows be requested via code? Moreover, can the refresh be requested only for windows displaying a particular location? I've thought of getting all open windows, filtering them and then sending the F5 keystroke, however it sounds a bit like overkill. Any easier way to do it?
We have developed a 'deployment tool' (say program A) which need to modify system registry, etc info which requires admin rights. This program will be triggered by another program (say program B).
Question, when B call A, how can B initiate A with admin rights? is there any command like A.exe /runas admin or any other way to achieve this. Please note that both programs are developed using VB6.
Is there a way in VB to make something that will simulate an advanced command prompt inside of a Windows Form? For example, something like a greenscreen app?
I've written a small program to open at startup, but I want to give the user the ability to delete it from showing on startup by clicking a button.But it needs to be compatible on XP, Vista and Windows 7. Is there a line of code which will get the default startup folder path automatically so I can then delete it using my button?
I'm havin a problem ive looked all over the net looking for an example of how to make my vb application run at startup by registry but i cannot find an example or how to do this that has actually worked for me
im tryin to make a application that could disable 2 services when when i run the application. so it would change it from say running automatically to disable. i have a lot of computers i have to administer, and i dont feel like goin one by one doing. Nd ima need radio buttons because a few machines are w7 and others r xp nd they each got diffrent services that have to be disabled.
actually i want to make my app startup with windows and in all Session . im using this code :
Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged If CheckBox1.Checked = True Then AddStartup()[code]....
doesnt work all the time , plus doesnt work in all user's session .. also i want to know if my app will keep settings . i mean i saved chekbox checked state in my.settings . does it keep it when the app start up?
Is there any other way to create a shortcut of an application programmatically or just make the application run every time windows loads up..I got this code of google but I am not too happy with it because it requires some assembly that other users might not have and I get an error when launching this feature on other computer could not load file or assembly interop.IWSHruntimelibrary..[code]
I developed an application in Visual Basic 2010 Express which has two features:
1) It is portable and uses some .dlls which must be in the same folder 2) Requires Administrator in order to run
I want my application to run on windows startup. So i created the registry string value and made some tests that gave me the following results:
1) Windows XP -> Runs on startup without any errors 2) Windows 7 Starter -> It simply ignores my application 3) Windows 7 Premium -> The run confirmation box from unknown publisher appeared and when i selected to run, AVG gave a virus warning 4) Windows 8 Consumer Preview -> It simply ignores my application
I am making a setup application and I need to know how to properly add a registry key so the application startup with windows. I have made what you can see on the image but I get an error when my PC restarts.This setup is nothing special I just need to make the registry key properly.
I am just wondering if you people will be able to help me make my application autload on windows startup (Like Windows Live Messenger does), I have been researching on the internet and I cannot find anything for it.
I'm trying to install an app on a windows server that is always on, but I'm running into problems. I've heard that I shouldn't make it a windows service (and would personally rather have a dialog app so I can see progress, etc) so I'm trying to use task scheduler. However, task scheduler keeps trying to close my app prematurely when it should only open it and leave it open.how I could have a dialog app run on startup (and stay running) on my server?
I have a checkbox "Run at startup" Private Sub chkStartup_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chkStartup.CheckedChanged If chkStartup.Checked = True Then Dim AppPath As String = "C:Documents and SettingsSamMy DocumentsVisual Studio 2008ProjectsImageShack vb.netImageShackAPIWrapperClientobjReleaseWebRequest.exe" [Code] ..... Works great but, what happens when I want to release it? How can I get the application to auto find its apppath??? So I dont have to write C: .....
Some software was installed on 8 XPSP2 PCs at 3 seperate times. 3 of the PCs, after installation, were restarted as per the installation instructions.When restarted, Windows XP displayed an error:The procedure entry point ___CxxFrameHandler3 could not be located in the dynamic link library Msvcrt.dll. and Windows will not start. (nor in Safemode)The problem I am having is that Msvcrt.dll is not shipped with the program, and from my research it is related to C++. The program is written in VB6 so I am confused.It could just be a coinsidence, but it only happens after the installation has told the user to restart the computer, so must be directly related to the installation. However, if the installation files were wrong or corrupt, NO installations would work correctly and we would have a problem on all of the PCs.
