.Net Application Does Not Comes In The Task Bar - But Can Be Seen While Doing Alt+Tab
May 26, 2011
My application displays a Splash Screen. In the Main form load event , we show another form in which user has to be select something. On the basis of that selection , the main form is loaded.
The scenario in which the main form is not shown in the task bar is :
1. Application runs , Splash screen is displayed.
2. a new window is shown to user to select something. this window comes over the splash screen.
3. Clicks ok on that window.The window is closed . Only splash screen is showing.
4.Now click on the space outside the Splash screen , the splash screen goes in backgound.
5. The main form is loaded. It comes for a moment in task bar but does not stay there. when i do alt+tab , it is there .

is it possible to make one application send a task to another application and recieve the result from that secondary app?i made a text editor program and i added a scan feature and i made another app that has ocr capabilities.The scanner ability is in my text editor program, the ocr program doesnt scan you have to input an image into it and it will give text result a few seconds later.the prob is alot of times the ocr code uses sooo much memory and crashes when its incorporated with my text editor, but individually each application works fine and doesnt take too much memory. Memory wont be even an issue if the ocr program is standalone so that when it is done decoding image the application can be made to exit. now here is the question, how do i make my text editor send the image to the ocr program and how do i make my ocr program send the text back to my text editor? is it possible? i mean the only way i know off is creating temp files in a certain folder and having a timer on each program that keeps waiting for temp files. That just seems like pretty lame coding to me i was wondering if there's a better way?

I have written an application in Visual Basic 2010 that I would like to hide from the Task Manager Application Tab, if possible. It's fine if it is listed in the Processes tab.
The purpose of the application is to allow users to postpone a restart following software update installations that require restarts. The application includes a form the user's must interact with so it can't be permanently hidden from view on the desktop. I am basically looking to mimic the WSUS Windows Update dialog which allows users to postpone restarts.
VB6 has app.taskvisible which is no longer included in VB 2010. I have seen a lot of discussion around this topic but no real solutions.

I am currently attempting to support a ClickOnce application that i did not write. This application is running from a scheduled task. The scheduled task points to a .application file. This had been running happily untill today when it stopped. The only thing that has changed is that the application has been executed manually by a developer by double clicking on the .application file. Since then each time the scheduled task is scheduled to run the application doesn't appear to execute. The task reports no error and the error code (0x0) given indicates it ran and completed ok.
I am not familiar with ClickOnce and am not sure when implication clicking the .application file would have had or why it has stopped running as a scheduled task. It appears to me that everything else has remained the same (i have checked it is running under the correct account etc).

I have created an application in VB2010 and deployed it such a way that it will start automatically when a user logins.I want user to restrict closing the application, so i disabled the close button also in the forms.But still users are able to close the application from Task Manager. Is there any option to restrict application closing even from task manager...?

In my application, the user can create a word document from a word template with dynamically added text and data to it. This happens on a backgroundworker so that the application doesn't hang during the process. This all works fine and the word document opens correctly when finished. Now if the user leaves the application to do something else, in most cases when they come back to it, it has frozen. It's still responding/running in task manager but the interface is frozen. In debug mode, it never freezes and so I can't catch the exact moment when the freeze occurs. My backgroundworker is disposed of when complete and I close everything related to the word object.

I'm going to create an application that will act as some sort of task manager. For stability reasons I will not use threads but processes instead. I have to deal with several third party libraries and/of COM servers that are not always that stable and can produce severe crashes sometimes. This may (of course) not affect the task manager
Problem with using processes is how to communicate with them? The process must f.e. give a status back of what it's doing every x seconds.
I was thinking of using TCP over a separate port per process, but is this the best way of doing this?

anyone knows the equivalent code for App.TaskVisible in VB.net? App.TaskVisible is from VB6 which hides the application in the applications list in task manager and not in the processes list tab.

I found some great code on capturing webcam images but the problem is the client PC will need to initiate the communication to this server (click Connect to server IP). This is like 2 way communication.How can i do something like this (door Kiosk system):when a visitor press a button on the LCD that come along a web cam (this will be the server), it will send the signal the client PC that is installed with the application i've created (window form) and pop up the images to the client PC (more like a 1 way communication). This image is captured through the web cam on the server to capture the visotor's image waiting outside of the door. How to do this?I'm really stuck as i'm not familiar with window API programming yet.
1) how to do the mentioned 1 way communication? possible in .NET?
2) how to make my application to be at the tray icon just next to the time displayed on the right bottom corner of the task bar? When a visitor press a button o the server, it will pop up a window form on the client PC showing the image captured via the server's webcam outside of the door.

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.

I am having fun working with System.Threading.Tasks. Many of the code samples I see, however, look something like so:
Dim lcTask = Task.Factory.StartNew(Sub() DoSomeWork())
Dim lcTaskLong = Task.Factory.StartNew(Sub() DoSomeWork(), TaskCreationOptions.LongRunning)
Task.WaitAll(lcTask, lcTaskLong)
That's the extent of the sample.Tasks implement IDisposable, so obviously I'm supposed to dispose of them, but what if I just want to "Fire and Forget"?If I don't dispose, will I leak threads/handles/memory/karma?Am I using tasks "wrong"? (Should just use a delegate and leave tasks alone?)
Can I dispose in a "ContinueWith()"? (That seems like playing Russian Roulette.)[URL]..

I have a MDI WinForms application that can perform several tasks. Each task is running as a backgroundWorker.What is the good approach to control the running threads:check whether the specific thread is running stop specific thread ?For example it shouldn't be possible to run the same task simultaneously.May be I need a separate class where I can store isTaskRunning variable?

I was wondering how to set a task in my program, For example if the user selects to take a screenshot on a chosen date and time the program would take that screenshot at the specified date and time. I have a DateTimePicker for my users to select a specific date and time to run the task. Since the date and time includes the date i don't think i can use a timer. And FX Cop said that timer intervals shouldn't be longer then a minute.
