IDE :: WinForms App Created Is Not Visible When Started By Vista Task Scheduler
Apr 28, 2010
It is a funny problem and I am wondering if anyone else has encountered the same problem using vs 2010 express on Vista Business. I can't tell if the App is running because I do not want to risk corrupting the sql 2008 express database.
is it guaranted that a task A started before TaskB will be completed before task B assuming the task do the same level of operatons?or in other words is there a chance that a task B will finish before tast A in the assumption that the task calls the same procedure?
I would like to know if its possible to check on the result 0x0 if scheduler run ok or 0x1 if it did not, but within .net, I found a post here but no resolutions so I am asking again just in case I get lucky.
I want to create a task scheduler in vb.net and I want to use the windows schedule wizard to schedule the tasks. So, how to link or call the windows schedule wizard in vb.net?
I have been working for some time on a service that will act as a task scheduler and perform a shutdown action at one of 3 given shutdown times. Before you cringe and ask why not use the task scheduler, I should explain that permissions do not allow users to "create" scheduled tasks and therefore a creative work-around is required. In any case, I am still new to VB, but am including my code below. I want the service to check an alarm time every minute and launch a shutdown application (in the user's context - if logged in) if that time is NOW.
I am running a vb.net win application from windows task scheduler. I would like to show a messagebox from my application in one scenario. How can I accomplish this. Code is getting executed, but messagebox is not getting displayed in my screen.
I have a VB program that is executed each morning at 4 AM by Task Scheduler. If the program returns anything other than a zero result, I would like Task Scheduler to run it again. The Task Scheduler sees my return code in the "Last Run Result" field, but does not invoke the "If task fails, restart every:" action.
creating small task scheduler in vb.net using in built library of vb.net . " I checked out Codeproject's ScheduleTask.dll solution (vb)"But problem is i want to create using inbuilt library of vb.net not using solution in vb.
I'm wanting to create a small application that will allow me to schedule a machine to shutdown at a specific time. Any suggestions on how I can make this .exe run at a specific time besides using the Task Scheduler?
If I create a scheduled task for my vb.net program, and run it under another user, and it runs when logged off, as long as the user has full rights, will the winforms application be able to call web services over the web?
I have an import program which I run manually everyday. I want to automate it but i'm not sure whether to make it a windows service or add it as a scheduled task. It needs to run at 11:00 and again at 16:00. Please advise
I'm upgrading from Windows XP 32-bit to Windows 7 64-bit, and I'm using VB in VS 2008. Under XP, I used the Task Scheduler to run a program at 3pm every weekday, and it ran fine. Now in W7, when the Task Scheduler runs the programs, it encounters an exception when it gets to the code MyForm.ShowDialog(). The error is:
System.InvalidOperationException was unhandled Message="Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application." Source="System.Windows.Forms"
[code].....
When I run the program from a shortcut with the same parameters as in the Task Scheduler (i.e. the shortcut runs the .exe file with some paramters after it), it runs fine, so I'm guessing there is some setting in the Windows 7 Task Scheduler I need to set, but I can't find it. I've tried checking "Run with highest privledges" (and unchecking it), but that didn't help. I have tried it with the "Hidden" box unchecked and checked and that didn't help. I've also tried it with "Configure for" set either way (Windows 7 or Vista). So how do I get rid of this error?
I have set up several tasks on a new installation of Windows 7 and they are working as expected.But when I attempted to run a batch file it fails. It works fine from the command line and I can run it from the scheduler on Windows XP manually (although not on the timer yet).What is about batch files that I need to know to make them run from the Task Scheduler?
I only know how to add your program to windows task scheduler to schedule automatic execution but what if you wanted to have a particular thread run on a weekly schedule. Someone mentioned windows powershell for all these types of scripting; but it seems too hard to learn on short notice.
So I wrote a VB.net project in Visual studio.I have a scheduled task that is set to run the program every morning at 10AM. If I use windows explorer and double click the application, it runs fine.If I open task scheduler, open the task properties, and browse to the application, then choose run, the program fails, due to Runtime exceptions.I know I have the path entered correctly, since I can debug the instance when it crashes from the task scheduler. VS2010 pulls up my source code.The exception is System.IO.FileNotFoundException, remember, it works fine when I double click the app. If attach a debugger to the process after it is executed from the task scheduler, I can then restart the debugger, and Voila!, The application runs fine.
automatic scheduler apart from creating windows service in .net or OS batch scheduler?I 'm aware of this two, Is there a 3rd way to create automated process in .net.I having facing limitations in creating windows service like I have semi admin rights so it doesn't allow me to install windows service also I can't view the windows service.
I was wondering if it is possible to add a button to the title bar in vb.net - I found a way to do this in one or the other but is it possible to do it on both?Here is the code that works if Aero is disabled (imports System.RunTime.InteropServices):
Can a form be Created that has Aero Glass when in Vista/Win7 and when running in XP or 98 use a regular border? If so can I have a link to the infromation or a code sample?
I am working on a wizard form framework that will allow me easily create wizard forms.I have a WizardForm form that has a panel on it. My plan is to dynamically load UserControls into this panel on the form.Each UserControl that is loaded onto the form panel must implement certain properties (allowNavigateNext, AllowNAvigate previous etc.). So I have created an interface to enforce that contract so that any custom user control can be used in the wizard as long as it implements that Interface. So far so good. created my first user control. I implemented the interface. All was good.I went to do the second user control and I realized that this second user control would have the EXACT SAME implementation of the interface as the first User Control. So...I thought...aha...duplicated code...how can I get rid of that.
I have taken over support for a VB.Net WinForms application. When this application is installed via a ClickOnce installation it generates a shortcut on the desktop. The annoying thing, though, is that if you do a right click and properties on the shortcut that was created, it is clear that it is not a regular shortcut as it does not have a target tab, so it is not obvious from the shortcut properties what this shortcut is referencing. So my questions relating to this are: what is the idea behind this kind of shortcut? Why is the the target for this type of shortcut hidden? (What are they even called? This is the first time I have ever seen a ClickOnce installation, so was somewhat surprised when I found that the properties tab was missing.) How do you find out what executable is being referenced by the shortcut?
Just moved from VB.NET to C#.In VB to connect and Event Handler to a Sub we use the Handles clause.From what it seems, this do not exist in C#. After creating a simple application with a button I realize that Window Forms Designer automatically created an EventHandler to my button1_Click function (after I double clicked it), in Form1.Designer.cs with this code:
this.button1.Click += new System.EventHandler(this.button1_Click);
But, in VB, the WinForms Designer create the Handles clause in my class, in the function header. So, C# create the default EventHandler in designer file, while VB creates in main class where control resides.
i compile my form with the below code when i run it on vista work fine without any problem but when i try to run in on XP cant run... that happened with any XP machine.[code]when i run my exe to other Vista machines work fine... but on xp NO.
I've got a panel - that's in a group box. All of this - with lots of other textboxes on labels - is in another panel (the big panel).I make the big panel visible and not visible based on selections made by the user.This small panel - that's in the group box. I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!
I have five menu items that i have created as a user control and placed on the master page. Now i want one of the menu items to be visible only for particular user role and not visible for others. Here is what I did. Its not working though.
I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.
