CSV to txt is trivial, a csv IS a text file, you'd just be changing what's in it. .xls would require you to interop with Office, obviously.

Hi.
In a few words, I have to convert a string retrieved from an Access database to a DateTime object.
I thought I'll use the Convert.ToDateTime() method. But there's the risk that the conversion will fail because the format will not be recognized. I think that this method uses the DateTime format taken from Contol Panel - Language Settings, so this would be tricky if the settings are different on another machine.
What would you do in this case?
Thanks.

I'd use TryParse to safly see if the conversion is possible. It'll also allow you to specify the format of the date:
System.DateTime.TryParse()[^]
|
|
|
|
|
DateTime.TryParse, but if it fails sometimes, then the other times, it's working because the day is < 13, and you're getting wrong dates.

Is it possible to retrieve the culture information for the machine running the application, and use that specific culture for the conversion?
|
|
|
|
|
I would store it in a culture neutral date format. Let the formatting of the date be taken care of on the client end where it belongs, and store the date using something like YYYY-MM-DD HH:MM:SS
|
|
|
|
|
Yes, but it shouldn't be stored as a string either.
|
|
|
|
|
For sure. But in this case it has to be this way.

1. Open prefered browser.
2. Navigate to google (or prefered search engine).
3. search for c# sms.
4. come back when you have a problem other than laziness :P
C# sms[^]
|
|
|
|
|
There are several articles on codeproject showing how to do it. Why don't you use search?

Hi!
I recently completed a project which sends/receives SMS to mobile phone and i used an open source API called GsmComm http://www.scampers.org/steve/sms/. Try it, its very useful. But if you don't wanna use API then i guess you will have to do a lot of hard work.

1 - try a meaningful subject line next time
2 - what do you want to cut/copy/paste/print ?
You've not come close to giving us enough information to expect an answer, try reading the guide on how to ask meaningful questions.

I'll make a deal with you -- you implement undo/redo in my program and I'll implement cut/copy/paste in yours.
|
|
|
|

Ooh Undo/Redo is pretty simple, just implement a Command design pattern with 2 methods on your Command interface
interface ICommand
void Undo()
void Redo()
Every action you want to perform then becomes a discreet Concrete Command object which implements whatever it wants as its undo/redo behaviour.
Whenever an action gets performed add it to a stack (undoStack). When undo is clicked pop the item off that stack, execute "Undo" and add it to another stack (redoStack). Whenever redo is clicked pop an item of the redoStack, execute "Redo" and add it to the undoStack.
Easy peasy.

Now that's the tricky part, isn't it -- the state that needs to be stored/maintained is what makes undo/redo a pain for me.

Just make your classes Serialixable.

hi,
I have a login form which uses a user control designed for solely login purposes.I have 3 projects in my solution, one is the main MDI application (PETALSApp), one is the control library housing the login user control (PETALSControlLib) and the other is one that has the login form(SecurityServiceProvider).
My idea is to open up a login form first and if the login is correct then close login window and open the MDI form.
Now the problem is, after the successful login, to close the login window i have written this.FindForm().Close() in the user control's code for successful login, but this code not only closes the login window, but it also closes the MDI main form. I have added references as folowing:
PETALSControlLib refers PETALSApp
SecurityServiceProvider refers PETALSApp and PETALSControlLib
Please help if there is a workaround for this

Once your log-in got validated try out the following
this.Hide (); // It will hide your current window.,
frmMDI objMDI = new frmMDI (); // Create instance of your new one
Application.DoEvents(); // To process all messages in Queue - NOT MUST
objMDI.ShowDialog (); // POP-UP it
|
|
|
|
|
hi, appreciate ur help, but Hide() would just make the form to vanish from the screen but it remains in memory and can be seen in task manager. just imagine if i open up 100 login windows, 100 instances would still be running in memory and this will lead memory performance issues. I need a workaround for this actually.

OK., i have assumed that as a Windows Application you would have only one instance, in your case i dont think so how it will work since once you close your main thread it will close entire stuff i.e there is no more resource to drive your application.
Lets say you log in screen page contains Main () method and you are expecting to close that one, hence there is no more main () then how it your application will work around?
Of course i might be wrong, if you come across any better soloution please post it across so that i can aware... 
Thanks
Siva
