Hello, CP. Lately I encountered a few articles here which discuss the topic of localization via Satellite Assemblies. While I understand the concept, and I have successfully implemented it in a small test project, I have a question. How do you go about localizing an application on a larger scale? For example, an application with many menus/sub-menus, dialogs, MDI children, etc. Is it necessary to create a method (or methods) which make statements such as:
private void SetUILanguage(string culture)
{
menuItem1.Text = resManager.GetString("menuItem1Text");
menuItem2.Text = resManager.GetString("menuItem2Text");
menuItem3.Text = resManager.GetString("menuItem3Text");
button1.Text = resManager.GetString("button1Text");
}
Or is there a simpler way to go about it that I am missing? I was thinking about possibly writing a method for a menu, which would iterate all menus/sub-menus (recursively) and load the resource string, also using the Tag property, like this (example):
private void SetMenuItemText(MenuItem item)
{
string stringName = string.Format("{0}Text", (string)item.Tag);
menuItem1.Text = resManager.getString(stringName);
}
However, would it be efficient/feasible to set the Tag property for every UI element and set the text this way?
Also, what is the best way to go about designing a UI (a data entry screen, for example) with localization in mind? Are there any resources online for that? I ask because a word in one supported language may be 7 characters long, while the same word in another supported language may be 13 or 14 characters long. How do you design the layout in order to compensate for that?
I came across this article on MSDN for the last question.

I made a wpf form to keep track of a volleyball match as it is played; it contains the layout of a volleyball court with six positions(6 different listboxes with the roster of the players). I want to be able to select any of the 6 listview boxes(make active), then be able to select a button (assist, serve, block, etc.) and be able to link the player with the action they performed and store it in a text file(actually I will put it into a SQL database in the future). I'm not sure if this 'linking' is the right way to associate the two, using a GUI interface like that? Any suggestions on what might work better? I'm not looking for code help right now, just the path to take to associate the two, and whether a listbox is the right choice here. Thanks for your help.

I would use the MVVM pattern (easily searchable, even on here) - Create a viewModel that has some methods on it, like UserPerformedAction(long UserID, EAction ActionTaken) (assumes an enum of actions here), or some such thing - have a view model store your data (such that when you decide where/how to store it, it's not impacting anything your UI is doing. Your viewmodel can have a collection of actions/items whether it's a class or a dictionary, etc. such that it can store the data cumulatively.
The other option is to make a domain object (e.g. UserKey, ActionTaken, DateTime) and pass this to/from your view model (e.g. UserPerformedAction(VolleyBallUserAction vbAction) - using objects makes it easier to later databind the gathered data in an output display of some kind.
So your UI calls ViewModel methods to store actions/request data, etc. And then you can decide what do to with the data now that it's collected in a central location.
That's what I would do, or something similar.

how to insert date ex(24/5/2012 2:30:00AM)into SQL database note that the date is current date come from textbox in the web page and then bind this field to gidview
(c# code)
|
|
|
|
|
using(SqlConnection conn = new SqlConnection("..."))
using(SqlCommand cmd = new SqlCommand("...", conn))
{
cmd.Parameters.AddWithValue("@date", date_value);
cmd.ExecuteNonQuery();
}
Failure is not an option; it's the default selection.

If you can use a DatePicker instead of a TextBox, life will become a whole lot easier.
1. It returns a DateTime object which can passed to your data access layer and saved to the database.
2. Users cannot enter invalid dates.
3. Date formats vary from country to country.
If the value is entered into a row currently displayed in the gidview, it may update automagically or the gidview may need refreshing.
You'll need to give more detail for the answer to be more specific. ASP.NET, MVC, WPF, MVVM, Winforms...

Does that allow one to select a time value as well? The OP said "24/5/2012 2:30:00AM"

Maybe, I don't know what technology you are talking about. Best just google and find out. There are also Time pickers. It just depends on your needs and what is available

The OP asked about storing a timestamp in a a database. You responded with a GUI component that only acts on a date.

I thought the OP was using a value entered into a textbox so giving advice or how best to validate that value before saving to DB. I should have mentioned a time picker as well. I wasn't aware it was a time stamp they were trying to save

Problem with HOGDescriptor
Hi everyone! I'm developing an object detection for a project interested in robotics. I've trained an Hog descriptor to be able to detect some boxes... When I've tried to use the constuctor public
HOGDescriptor(
Size winSize,
Size blockSize,
Size blockStride,
Size cellSize,
int nbins,
int derivAperture,
double winSigma,
double L2HysThreshold,
bool gammaCorrection
) hog;
-> HOGDescriptor des = new HOGDescriptor(new Size(64, 64), new Size(16, 16), new Size(8, 8), new Size(8, 8), 9, 0, -1, 0.2, true);
with a winSize(64, 64)[different from default size of (64, 128)] for use my vector of float in
hog.SetSVMDetector(vector)
Visual studio give me a "NullReferenceException"... but I've instantiated both hog than vector! So why? I've failed in writing the constructor?
Also the parallelism with openCV is different, in fact the costructor in openCV is
HOGDescriptor(Size win_size=Size(64, 128), Size block_size=Size(16, 16),
Size block_stride=Size(8, 8), Size cell_size=Size(8, 8),
int nbins=9, double win_sigma=DEFAULT_WIN_SIGMA,
double threshold_L2hys=0.2, bool gamma_correction=true,
int nlevels=DEFAULT_NLEVELS);
but derivAperture there isn't!!!
Please help me!

Please use <pre> tags so your code looks readable, like this:
HOGDescriptor des = new HOGDescriptor(new Size(64, 64), new Size(16, 16), new Size(8, 8), new Size(8, 8), 9, 0, -1, 0.2, true);
hog.SetSVMDetector(vector)
Did you notice the difference between the two object names?

I try to explain...
I'm using EMGU, a wrapper for OpenCV's libraries. I'm trying to do an object detector (who detect boxes), starting from the Example "Pedestrian Detection" (it's inside the Emgu's packet http://www.emgu.com/wiki/index.php/Pedestrian_Detection_in_CSharp[^])
I know that the default constructor accept these values
HOGDescriptor des = new HOGDescriptor(new Size(64, 128), new Size(16,16), new Size(8, 8), new Size(8, 8), 9, 0, -1, 0.2, true);
The first value in constructor, (64,128), is the size of images used to create the HogDetector able to pursue a human figure.
But I've to use images (64, 64) to pursue boxes...and when I use these parameter, visual studio give me a null reference exception.
So, the wrapper may be used only with default value?
I talk with people who had used EMGU yet...Thanks!

I suggest you put a break point in your HogDescriptor constructor and step through the method. I would guess you are assigning a parameter to a property that has not been instantiated in the constructor.

I've used a break point yet....and, both the HogDescriptor and the vector of float are instantiated
|

Did you read my previous response? You are instantiating an object called des and then calling a method on an object called hog. Did you ever initialise hog? You also omitted to explain clearly which line of code gave the exception.

My code is only
1. float[] vector= ...
2. HOGDescriptor des = new HOGDescriptor(new Size(64, 64), new Size(16, 16), new Size(8, 8), new Size(8, 8), 9, 0, -1, 0.2, true);
3. hog.SetSVMDetector(vector)
And the exception is on line 3.)
The object 'hog' is only an example name, used to see the constructor....
|
|
|
|
|
OK, for the third time: you instantiate an object named des then call a method on an object named hog. If you still do not see a problem then I'm afraid I am at a loss as to how to make it more clear.

|

Sorry... I want to write like this:
1. float[] vector= ...
2. HOGDescriptor des = new HOGDescriptor(new Size(64, 64), new Size(16, 16), new Size(8, 8), new Size(8, 8), 9, 0, -1, 0.2, true);
3. des.SetSVMDetector(vector)

Why not stop posting what you think your code should look like and post the exact code as copied from your source file, and show the exact, full text of the exception or compiler message you receive?
|
|

|

I know that there's a problem with the EMGU wrapper constructor of HogDescriptor...I've posted this question hoping to find some people good with EMGU...

Hey,
I have been struggling to bind a combo box and a text box.Finally it happened, but unfortunately the text that i have selected in the combo appears with additional wordings.
Ex : I select the word " FISH" from the combo , so i expect that word to appear in text box that i have bind.But instead of that System.Windows.Controls.ComboBoxItem: fish appears.How to solve this.Please tel me how to correct this in design view or by xaml.Thank you
|

you need to set the path to Selected value in the binding. refer below code
<TextBox Height="23" HorizontalAlignment="Left" Margin="126,167,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding ElementName=comboBox1, Path=SelectedValue}"/>
<ComboBox Height="23" HorizontalAlignment="Left" Margin="132,62,0,0" Name="comboBox1" VerticalAlignment="Top" Width="180" ItemsSource="{Binding CMBItems}" />
in the code expose property as
public List<string> CMBItems
{
get
{
return new List<string> { "a","b","c","d"};
}
}
Hope this will help!
Happy Coding
