I am trying to display a dialog for a period of time. if the user is not present, I want it to close and perform a task. I am using a background worker, which is supposed to simulate a button click. It performs the button click fine, but the dialog never goes away.

I am developing an application that prompts an user for doing certain tasks in a form. What i want is that a certain message should be popped for a certain amount of time and then close (probably say 2 seconds or so). I tried doing it with message boxes but they do not close on their own as they are designed to be modal (to wait for user command ). i do not want to display the text in a textbox of listbox. Is there a certain way i could do this.

As I want the user to be able to connect to various database using the GUI.
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?

I have implemented a system where the are 18 text boxes (9 for questions, 9 for answers) and it can be customised but I want the questions to be able to be 'saved's since it in another form the if I give them special names when I close the form and open it again it has lost the values. Is there a way to remember the variables for a set period of time (cookies?) or if not just for that session?

View 1 RepliesIs there a way to code, so that if your program freezes over a period of time (5sec), it just stops trying to do it, and goto something else.
"On ERROR" wont work, since its not a error. "Try" doesnt work ether.
Its because I'm am programming something that can login to a router thought telnet, and sometimes the telnet ActiveX doesn't read the buffer or the line proberly, so when the .GetLine() func is called, it freezes. And i want away to goto another point if it keeps freezing for more than 5secounds. The telnet ActiveX that, I am using is Dimac w3sock.

I have looked through couple of threads about making the trial application to be expired within certain time. Most of the advice is to set a timer and store it in somewhere in the system with encrytion. Then later decrypt and compare with the date installed in the system.
View 12 RepliesI know about DateDiff and TimeSpan. I am doing a project. I save a date in the registry. Now, I have to test this date against today's date and calculate the differences in minutes, hours, days, months, weeks and years.
I save the date in the registry like this:
Application.UserAppDataRegistry.SetValue("Date", [Date])
I then made a sub to calculate the differences:
Private Sub Calculate()
Try
Dim DateGen As Date
DateGen = CType([Date], Date)
Select Case TimePeriod
[Code] .....
As you can see, based on the difference between these dates ( today's date and the registry date ), a sub gets called and the program continues. Unfortunately, the minutes and hours never calls the RandomAlpha sub. How can I calculate the difference in minutes, hours etc.????

View 8 RepliesI'm rather new to programming in general, but I have written a rather useful program for the company I work for. What I am trying to do is control the way a dialog box is displayed. I want a dialog box to pop up at certain times like 7:00 PM, 8:00 PM, etc.
View 1 RepliesI have a large VB.Net 2008 rich client database app and in it some screens take a bit to load, 1 - 5 seconds and two of them take up to 15 seconds. Right now I have a me.hide in my form load, I do my loading of drop downs and data, then do a me.show. It works decent and gives the impression that the program is quick. What I would like to do however is have a "waiting" or "loading" screen with a animated gif pop up while it's doing its data loads.
So I created a "WaitingForm" that has no border and a single picture box. In the form load of this waiting form it assigns a animated gif to the picture box. I set the form to be top most, no control box, etc.
If I call this waiting from from within my from load events as WaitingForm.show the animation doesn't work and the form only half shows (and in the wrong place on the screen). If I call this form using a WaitingForm.ShowDialog it correctly shows in the center of it's parent and displays the animated icon BUT blocks the calling form from processing and defeats the entire purpose.
How do I display the waiting form like it's a dialog box so it correct centers on it's parent and displays correctly but doesn't block the lower form from processing? Currently when I call the waiting form I give it a integer for how many seconds to display and then a timer on the waiting form counts down and closes itself. Do I need to use a worker thread and if so what is the easiest way to do this so the code is reusable from multiple different screens?
I'm calling one program from another using the shell command. When I call the second program it loads a file and then displays the details on the screen. But when it runs nothing appears to happen and it is only when the file is loaded that anything is displayed. One of the first things that happens is a Resize, so I expect the dialog box to be displayed, I have added a refresh at the start but the dialog box is still not displayed untill the file is loaded. How can I make the program display the dialog box at the start to show something is happening?
