Because you set the tick time to a specific value, means that it fires at that interval, not that it fires at a specific time: it doesn't add the tick interval to the system clock when you start the timer, it sets a specific number of ticks that should elapse before the timer event is fired. Changing the system clock does not affect that tick count, so if you set a timer for one hour and then move the clock forward 59 minutes, it will still be an hour before the timer fires.
If you want to first at a time, then set the timer interval to 30 seconds, and set a class level DateTime value at which you want to call your method. In the tick handler, compare the current time to the class level value and call your method if it matches. That way, you can reset the clock after it fires, and it will match a second time.

can u plzz post some sample what u said "If you want to first at a time, then set the timer interval to 30 seconds, and set a class level DateTime value at which you want to call your method. In the tick handler, compare the current time to the class level value and call your method if it matches. That way, you can reset the clock after it fires, and it will match a second time."

You should be able to do that yourself, if you wrote the code you show! You know how to set the interval on the timer, and you know how to create variables...

- call your timer (for example) every Minute - set timer.tick to 60000
- when you have the timer.event don't stop the timer
- compare if now is greater or equal your schedule-time, but less your schedule-time +30 seconds - if yes the give the message and increase your schedule-time

Didn't really know where to ask this so went for the lowest common denominated forum! C# FTW!
Anyway, I was wondering if this was a problem that had already been solved but I'm not aware of the generalised approach.
I have an MvvmCross based solution that uses SQLite as the data store. All the common functional goodness is in a core PCL project, all fine and dandy. In this core PCL I have the data access stuff along with resx files containing any strings needed in the various application UI projects.
When the application starts up it initialises a connection to the SQLite database. If the database doesn't yet exist and requires creation (think very first run of the application) it needs to create the database and populate it with some initial data (just for ease of setup with some generic lookup data). This data is fully editable by the user but this is more of a convenience task to get the user up and running quickly without burdening them with loads of config before being able to do something useful.
What I'm looking at is using localised resx data for the source of this look-up data. I can think of a few ways of doing this but before I pop off and roll a solution I was wondering if there were any generalised approaches to this scenario that people had used before.
Googling hasn't turned anything up thus far so I thought I'd cast the net out to you lot first.

I wasn't really looking for general information on app globalisation, I've developed a few globalised apps in my time but I've not been in my current specific situation and wondered if there was a relevant pattern.
Thanks anyway.

The "recommended patterns" are there. I find it's not worth the effort to go against the grain in these situations. Adopt; then extend, if necessary.

I might not have explained my question properly to be honest.
Localising an application using Resx and custom UI binders for XAML, iOS and Android Xamarin apps is fine. I've done all these things before. Handling RTL globalisation in WPF apps is also something I've done before as well.
I was basically looking for inspiration regarding taking localised strings from RESX files and populating various database tables with lookup values for things.
What I've ended up doing is implementing the Builder pattern to aggregate key value pairs from these RESX files and utilising my repository pattern bits to automatically populate these lookup tables on the initial creation of the SQLite db3 file.
My base builder class looks like this (not perfect by a long shot, there is no abstraction of the connection I can use for instance):
public abstract class LookupBuilderBase<T> where T : class, IEntity, new()
{
protected SQLiteAsyncConnection AsyncConnection;
protected IDictionary<string, string> LookupData;
protected IRepository<T> Repository;
protected readonly IList<T> Data = new List<T>();
protected LookupBuilderBase(SQLiteAsyncConnection conn, IDictionary<string, string> lookupData)
{
AsyncConnection = conn;
LookupData = lookupData;
}
public async Task Execute()
{
CreateRepository();
BuildData();
await InsertData();
}
protected abstract void BuildData();
protected virtual async Task InsertData()
{
foreach (var item in Data)
{
await Repository.Insert(item);
}
}
private void CreateRepository()
{
Repository = new Repository<T>(AsyncConnection);
}
}
I can then write builders like this:
public class CategoryBuilder : LookupBuilderBase<Category>
{
public CategoryBuilder(SQLiteAsyncConnection conn, IDictionary<string, string> lookupData)
: base(conn, lookupData)
{
}
protected override void BuildData()
{
var values = LookupData.Where(x => x.Key.StartsWith("Category"));
foreach (var keyValuePair in values)
{
Data.Add(new Category { Name = keyValuePair.Value });
}
}
}

I would have a single table (for a given "dimension") and have columns for each resource.
At run-time, using Linq, or C# / SQL "views" (or some other magic), I would materialize only the column that the app's locale required.

It's either a case of filter what you're interested in on the way into the database or shove it all in there and filter on the way out of the database.
I opted to only put relevant stuff into the database which means that considering the data is 99.99999999% handled in reads not writes I opted to make the read more efficient.

"Shove it in there"?
It becomes THE repository for your resources; and not just some "staging area".

That's what RESX files are ...
|
|
|
|
|
Then why are you loading them into a table....

In the instance of Categories it's because they are simple lookup values loaded into a view model for, for example, binding to a combobox. BUT they are also useful as values used in foreign key relationship in the database.
Resex is the best way to handle automatic localisation utilising standardised approaches for this in the .NET framework but also have value in the database.

I see.
I, however, would not think twice about loading it all into a database if I had to "share" in the ways you describe; let alone report on and cross-check all this stuff for any sizable project.
Resx internals are simple; there is nothing stopping one from importing or exporting them.
It's a question of which "smell" one prefers then.
In any case, the "assets" are separated from the "code"; the whole point of "resource files" (whatever the implementation).

Not sure if I understood your issue completely. Since you want to let the user edit the texts, you opted for storing them in a database instead of resx files, but still want to use resx files for development, isn't it? I'd suggest to get rid of those resx files here, handle the localization completely in the database (I think software translation shops can handle that, too), thus no need to feed them from the files into the database.

I have the following code structure:
[CODE]
bool bStop = true;
int RowCount = 65000;
private void btnRun_Click(object sender, EventArgs e)
{
int i = 0;
//int iErr;
while (i < dataGridView1.Rows.Count - 1 && bStop)//Loop 1
{
while (i < dataGridView1.Rows.Count - 1 && bStop)// Loop 2
{
try
{
if (i > 0) dataGridView1.Rows[i-1].Selected = false;
dataGridView1.Rows[i].Selected = true;
dataGridView1["ROWS", i].Value = "Processing...";
System.Windows.Forms.Application.DoEvents();
Thread.Sleep(1000);
Debug.Print("are in Try and i: " + i);
}
catch (Exception ex)
{
Debug.Print("are in Catch and i: " + i + " ex: " + ex.Message);
}
i++;
}
}
}
[/CODE]

It does - that's the whole point.
You use the try block to catch and handle exceptions, and the code will continue from the line immediately after the catch block.
Since your whole try...catch block is inside your loop, the loop will continue:
int j = 0;
for (int i = 0; i < 5; i++)
{
Console.WriteLine(i);
try
{
i = i / j;
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
Gives:
0
Attempted to divide by zero.
1
Attempted to divide by zero.
2
Attempted to divide by zero.
3
Attempted to divide by zero.
4
Attempted to divide by zero.

I ran outside with structures on the run very good but when I use add the AT command set and add progress is no way to escape the catch, you know what commands to delete all errors in the catch ?

I'm sorry, but that didn't make any sense to me - it may be that I haven't had my ![Java | [Coffee]](https://www.codeproject.com/script/Forums/Images/coffee.gif) yet, but I'm working on it - could you try again, this time remembering that I can't see your screen or access your HDD, and only get exactly what you type to work from?

Dear
I'm newbie and i'm developing a Windows Service which should make same tasks according some REGISTRY KEY i will populate during Setup Setup (based on VS c# Setup Project).
I need to rollback installation before complete installation if during Setup a web request i run give me back some errors or some special return value.
How can I do using custom action ?
thx

Don't use the registry unless you have no other option: access to it is now restricted, and likely to become more so, not less.
Instead, consider using an XML file (or similar) stored in a more accessible location. Windows provides several: Where should I store my data?[^] and it's a lot easier to just dump a folder on rollback than play with the registry.
