Hi Team,
I have a C# app where the only localization that needs to be done is in the Menu Strings. So instead of the strings being stored in a resx file (OR BAML), I was thinking of storing that in a keyvalue pair .properties file that can be dynamically updated from a CDN. This way if a new locale has to be supported, all we need to do is add the corresponding property file for that locale.
Anyone tried this approach and any recommendations/things I have to take care of?
Thanks,
Chandra

Good morning, i would like to develop a fingerprint students attendance, But the problem i face is not sure how and where to start. The help provided really will be helpful to me. I will develop using c# provided by digital persona sdk. i have basic knowledge in c# but able to lern.

The first thing you need is a fingerprint reader. A study of its documentation will get you started.

Just be sure you get the most recent SDK. At least in prior versions of the Digital Persona SDK, there's at least one really serious memory leak when using a Streamed image from the 4500 / 5100 series readers.
Also, under existing privacy laws, fingerprints fall under protections for PII -- personally identifying information. So students or not, you have to be really careful about what you do with the fingerprint records.

Saving information to a database is nothing to do with a fingerprint reader. Once you have the input data from the reader you just send it to your database in the same way you would any other input data.

owh... thanks Richard.. now i got soem idea... i researching more in how to save to database directly. You are helpful sir... i try research and find out how to do that.. or is there any link i can go through sir, sir can share..

Yes, www.google.com[^]. But you need to explain your problem more clearly. We have no idea which database you are using or what problems you are having with it. If you are still learning about databases then Google will find you many samples and tutorials.

i am using oracle as my databse. The problem is i not sure how would it save the fingerprint to the database..
|

It depends on what you retrieve from the fingerprint reader. The data that it provides is presumably a digitised representation of an image, so that is what you need to save. Whether you save it in the database, as a blob, or as a normal file with a link in the database is up to you. But the first thing to do is undertstand the format of the data that the reader provides.
|
|
|
|
|
owh.. now i have some idea.. i try and see on the format that the reader will save... if i have other question i would ask.. and thanks alot as without ur help i will be blur on where to start thanks..

Hi all,
I have a mdi application which have Form1 and Form2 each form has a public Function named MyPrint(). So I want to create a button on the MDI parent form which will call the MyPrint() function of the ActiveMdiChild form i.e:
Form curForm=new Form();
curForm.Print();
how to make it possible to call MyPrint() of each form implicitly.
thanks in advance

The way I would do it is to create a form derived from Form which includes an overridable MyPrint method, and derive my MDI children from that. That way, the main form can call the correct version without explicitly knowing which it needs to look for.
But your code fragment won't do it: that creates a new form rather than trying to access a method in an existing displayed form. Try looking at the Form.ActiveMdiChild Property (System.Windows.Forms)[^] instead.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

It's a mistake to place any Control on the MDIParent Form surface: it will then appear above all MDI Windows that may be "under" it, and make a visual mess. If you must have a Button, place it in a MenuStrip on the MDIParent Form.
One way to get the "implicit" functionality you describe is to define an Extension Method on the Form Class for printing:
using System;
using System.Windows.Forms;
namespace YourMDINameSpace
{
public static class FormExtensions
{
public static void Form_Print(this Form form)
{
Console.WriteLine("{0} is printing now", form.Name);
}
}
}If you drag-drop a MenuStrip onto the MDIParent Form, you can then choose the option for it to insert the standard items which will include a 'File Menu with a 'Print sub-menu item. By defining an EventHandler for that 'Print menu-item, you can write your code that handles printing:
private void printToolStripMenuItem_Click(object sender, EventArgs e)
{
if(ActiveMdiChild != null) ActiveMdiChild.Form_Print();
}The code shown here assumes you have implemented the Extension shown above; note that you use the 'ActiveMDIChild directly to invoke the method.

An alternative approach is to use an interface to describe the method you want to use and then let each form implement it, only if it needs to print. So, you would have something that looks like this:
public interface IPrint
{
void Print();
}Then, when you need to print, you would have something that looks a bit like this in the code that calls Print.
if (ActiveMdiChild != null)
{
IPrint printForm = ActiveMdiChild as IPrint;
if (printForm != null)
{
printForm.Print();
}
}

You could simplify that by removing the outer if block - if ActiveMdiChild is null, then ActiveMdiChild as IPrint will also be null.
IPrint printForm = ActiveMdiChild as IPrint;
if (printForm != null)
{
printForm.Print();
}

I want to use a DataBase Connection which is open to an IValueConverter. The Language is C# and the Framework 4.5. The Database Connection is created whith Npgsql to an Postgres Database.
namespace WpfApplication
{
public class GetToltipStatus : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
!!HERE I NEED THE CONNECTION CONN!!
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
public partial class Tab_100 : System.Windows.Controls.UserControl
{
public NpgsqlConnection conn;
public Tab_100(NpgsqlConnection conn100)
{
conn = conn100;
}
}
The Mehtode Tab_100 is started and get an opened Database Connection (conn100). For the IValueConverter I need this. I could not use an public static Connection and because of that I colud not access like Tab_100.conn. Is there an other way to get the Connection from the class Tab_100 in the IValueConverter ?

You shouldn't be attempting to access the database directly from a value converter. If you are using MVVM,you should be interacting with a Model from your ViewModel.

Is there a way to take a base color and create a color wheel array in memory of gradient colors from that base color?
|

See this[^] article.

How about clarifying the purpose of this in-memory gradient, keeping in mind that there are a variety of gradient types (circular, linear, etc.). I assume you'll be using the gradient at some point as a user interface element: what will that look at.
Creating a linear gradient from Color1 to Color2 to be displayed on the surface of a Control is straightforward.
Is this WinForms, WPF, HTML5, ASP.NET ... or, ????
