Hello,
[2005]
I have form that uses a timer control. The user can stop, start and reset this timer. The idea of this timer is to log how long a engineer has taken to complete a specific job. The user will stop the timer by clicking a button on the form.
However, the problem is that the user can close the form and when they do the timer will automatically stop.
I am looking for a solution what will allow the timer to function after form has been closed and when the form is re-opened no time has been lost.
I know that the timer will run in the UI thread, so is it worth creating another thread for the actual timer control?
This is a mdi application, is it a better solution to have the timer control placed on the parent?
Many thanks for any suggestions and ideas,
Steve

You obviously need to store the timer outside the form, so that whereever it is, it will keep running. Making it static (shared) may work, I am not sure.

You might also look into stopping them from closing the form and hide it instead when they try to close it.

It seems likely to me that the classes to do this will have changed so utterly that your best bet is a rewrite

Hello,
I am working on a custom control which has 'items' the only thing left to do which has me stumped is getting the items to persist.. I have searched around but am either looking for the wrong thing or there isnt a simple tutorial out there.. because when I add items at design time they disappear once I build/run my application.
Can anyone help or point me in the right direction?
Thanks
Ian.

Hi Ian ... I'm also interested in this as well .. I've posted a similar message here re: serialization ... which is one metod ... but I've not had any success with my attempts at getting it to work ... I'm hoping we might get an expert answer from one of the more knowledgable here on the forum .. fingers crossed ...

I want to write a windows service that shuts down the computer between 4:30am and 5:30 am every morning provided nobody is currently logged in. The computer is running XP professional, and the windows service I wrote uses the account "LocalSystem".
I have been able to create a windows service, and determine if anyone is logged in but I am running into problems with the shutdown command. I have a timer to check if conditions are right (ie. nobody logged in, and within the specified reboot time interval) and then I run the following code to shut down the system:
System.Diagnostics.Process.Start("Shutdown", "-s -t 1")
I can't seem to get this to work unless I am logged in. If I am not logged it, it does nothing until I log in and then immediately shuts me down. "Shutdown" seems to require a logged in user. Is there a way to shutdown the computer when I am not logged in?
Thanks.

I am guessing it has to do with some of the setting on the process. There are some things you can set like
Process.StartInfo.CreateNoWindow = false
Hope that helps.

At runtime I have a button and other controls that load images from a file,
below is one example,
DIYButton.BackgroundImage = Image.FromFile(ChosenPath & "\DIY.gif")
What I want is to have it load the image, if it's a gif or jpg
How do I go about it?
|
|
|
|
|
Something like this, maybe:
If My.Computer.FileSystem.FileExists(ChosenPath & "\DIY.gif") = True Then
DIYButton.BackgroundImage = Image.FromFile(ChosenPath & "\DIY.gif")
ElseIf My.Computer.FileSystem.FileExists(ChosenPath & "\DIY.jpg") = True Then
DIYButton.BackgroundImage = Image.FromFile(ChosenPath & "\DIY.jpg")
End If
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

You can name the file whatever you like, it will still open as either a gif or jpeg, based on it's format. You can use File.Exists to check if the file is there in either format, also.

In the code for your LinkButton type: Process.Start("http://www.example.com"). This will open a new tab/window in your default browser.

I have looked for ever for this information. Does anyone know of a good tutorial or description of how to receive information from the sound card, c#,VB.net or VBA preferably. I am a ham radio operator and would like to write my own Morse Code decoder via sound card interface. There are many out there but I want to integrate this into a radio control program

You put this in a Dispose implementation?? What are you trying to do with this code? This is something you would normally find in a form's Closing event, not Dispose.

Hi:
Supouse I have this Table in a Access database:
Table Name: CostumersType
Fields: ID(Autonumber),Name(text(50)), Costumers(object)
And this Class
Class Name: Costumers
Class Properties: name(string),id(integer)
And i add some items of the class costumers to an arraylist called Costumers.
Then I want to save the content of the arraylist to the field costumer of the database. And I don't know how.

This is not a possible i think and not a good approach either.
Why you need to put arraylist in the table field?

Hi,
I developed an windows application that inserts some values into database.It is working fine.But now i have two problems
1) I prepared an exe file for my application and installed in another system. When i executed my application in that system it given me error as it doesn't find database. I have given the Datasource as "Data Source=D:\Dotnet\SurveyApp\SurveyApp\SurveyData.mdb".
Can any one suggest me what i have to do to solve this
2)I have another doubt i.e is it necessary that ms access should be installed the syystem where i installed my application?
Please help me solve
Thanks

And is that the location of the database on the new machine? If not then it seems fairly obvious to me that you need to change the location of the database in the datasource. If this value is hard coded then you might want to learn the lesson not to hard code file paths in an application.
So, where is the database now?
vijay2583 wrote: I have another doubt i.e is it necessary that ms access should be installed the syystem where i installed my application?
That depends. Do you intend to share the data? If yes, then SQL Server is probably a better option as it is more able to share data between multiple machines. If not, then you probably want to copy the database.
