  • Is a Multi-DAL Approach the way to go here?

    - by Krisc
    Working on the data access / model layer in this little MVC2 project and trying to think things out to future projects. I have a database with some basic tables and I have classes in the model layer that represent them. I obviously need something to connect the two. The easiest is to provide some sort of 'provider' that can run operations on the database and return objects. But this is for a website that would potentially be used "a lot" (I know, very general) so I want to cache results from the data layer and keep the cache updated as new data is generated. This question deals with how best to approach this problem of dual DALS. One that returns cached data when possible and goes to the data layer when there is a cache miss. But more importantly, how to integrate the core provider (thing that goes into database) with the caching layer so that it too can rely on cached objects rather than creating new ones. Right now I have the following interfaces: IDataProvider is used to reach the database. It doesn't concern itself with the meaning of the objects it produces, but simply the way to produce them. interface IDataProvider{ // Select, Update, Create, et cetera access IEnumerable<Entry> GetEntries(); Entry GetEntryById(int id); } IDataManager is a layer that sits on top of the IDataProvider layer and manages the cache interface IDataManager : IDataProvider{ void ClearCache(); } Note that in practice the IDataManager implementation will have useful helper functions to add objects to their related cache stores. (In the future I may define other functions on the interface) I guess what I am looking for is the best way to approach a loop back from the IDataProvider implementations so that they can access the cache. Or a different approach entirely may be in order? I am not very interested in 3rd party products at the moment as I am interested in the design of these things much more than this specific implementation. Edit: I realize the title may be a bit misleading. I apologize for that... not sure what to call this question.

  • How to configure bugzilla to not advance to next bug when updating?

    - by WilliamKF
    By default, when you apply changes to a Bugzilla entry, the web interface advances to the next bug in your list. I would like to disable this feature since it is almost never what I desire, planning to make further updates later. Further, I often update the wrong bug subsequently due to its changing the current bug without my noticing. How do I configure Bugzilla to not advance like this?

    - by rlb.usa
    I have an ASP.NET web application for data entry, and we have big lists of radiobuttons, and long lists of checkboxes, in some sections. The client wants to be able to be able to navigate and manipulate these controls with their keyboard, like the tab/space/enter/right-left-up-down-arrow-keys. Are there any ASP.NET controls that I can use?

  • How can I make xmlpp::DomParser less verbose on errors?

    - by Beau Simensen
    How can I make xmlpp::DomParser be less verbose on errors? Right now, if parsing fails, I get a bunch of text printed to my console and I'd just as soon have that not be visible. Entity: line 1: parser error : Opening and ending tag mismatch: feed line 1 and fed <feed><entry id='5' /></fed> I don't see a lot of options for xmlpp::DomParser but I have to believe this is something that can be disabled/tweaked.

  • Getting a Soft Keyboard for a EditTextPreference

    - by user313135
    Hello, I have a shared preference that is being accesed via an EditTextPreference. I am in the process of porting this application to a device that does not have a hardware keyboard for text entry. When the time comes to modify the EditTextPreference, there is no soft keyboard that becomes available, and I am at a loss as to how to invoke the soft keyboard for text input to edit this preference. Thanks

  • MS Access 2007 - Property for text box to allow end-user to hit enter for return, not next

    - by Justin
    So I have a form that user's use for data entry, and on one form there is a text box there that is basically used. To enter notes. However, if the user hits i need the cursor to stay in that text box, and start a new line (uh....like word would)....but currently it is jumping to the next control (text box). So is there a simple property setting that would do the trick? Or a VBA method to accomplish? Thanks Justin

  • Inserting Strings Without Trailing Spaces SQL

    - by Soo
    I have a database with a field named Field1 that has 100 nchars per entry. Each time I add a value, it is stored as: "value (100-ValueLength Spaces) " So Basically each stored value has a string of spaces after it. This is getting to be an issue when I try doing: if (value == "Example") because of all of the empty spaces after the string. How can I get it so the stored values don't have all of these trailing spaces?

  • How can a button click method find out which item is selected in a ListView?

    - by Ian Bayley
    I have a single screen with a bank of buttons below a ListView. Entries on the ListView light up in orange when I scroll so I assume that are selected. When I then press the "Delete" button I want the onClickListener to remove the currently selected entry. But getSelectedItemPosition() always gives me -1. If I can't hope to use the GUI controls in this way, please give me another way of getting the same result. I have even tried setting the onClickListener of the List View to store the index before the button is pressed (in case pressing the button unselects the entry) but even that is always -1 it seems. Here's the code (without the modification which didn't work) package com.bayley; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.Button; import android.widget.EditText; import android.widget.ListView; import java.util.ArrayList; /** * * @author p0074564 */ public class September extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); final ListView myListView = (ListView) findViewById(R.id.myListView); Button addButton = (Button) findViewById(R.id.AddButton); Button deleteButton = (Button) findViewById(R.id.DeleteButton); final EditText editText = (EditText) findViewById(R.id.myEditText); final ArrayList<String> todoItems = new ArrayList<String>(); todoItems.add("Monday"); todoItems.add("Tuesday"); todoItems.add("Wednesday"); final ArrayAdapter<String> aa = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, todoItems); myListView.setAdapter(aa); addButton.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { todoItems.add(editText.getText().toString()); aa.notifyDataSetChanged(); } }); deleteButton.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { // always returns -1 unfortunately ie nothing is ever selected int index = myListView.getSelectedItemPosition(); if (index >= 0) { todoItems.remove(index); } aa.notifyDataSetChanged(); } }); } }

    I am new to DDD. In my mini-project, I have a structure that looks like this (different from the actual names): EntryClassificationGroup EntryClassification Entry EntryType Should I have just one repository class for all these 4 entities, since they are all related? Or should I have individual repositories for each one?

  • Is there a way to prevent a string of letters with no spaces from overflowing out of its correspondi

    - by Scarface
    The question is pretty straight forward, I have tried using a span with rules set to clear:both; and display:block;, at the bottom of each list entry where the text is being inserted in with no luck. I am not really sure what to do on this. I don't expect to many entries with long consecutive letter strings but for example if someone does lolololololol or ahaahahahhhhhhhhhhhhaaaaaaaa for like 100 letters, it will overflow. If anyone can give me a pointer I would really appreciate it.

  • Microsoft JScript runtime error: ASPx is undefined

    - by Joe
    I'm getting this error all over the place in my web application and trying to figure out why. The error is always for some control, ASPxClientTextBox for example. So far the only thing I've found as a potential fix is to check the httphandlers section of the .net web.config (the one in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\web.config) and make sure an entry for "WebResource.axd" exists, which it does. Any idea's what's going on or where I should look?

  • Watin: file upload ...without file selection window?

    - by user526186
    with "file upload" HTML like this: <input name="input_name" type="file" size="40" /> ...there is no way for users to directly enter text into input area for security reasons, correct? file selection window pops up instead. In Watin automation project, we are wanting to bypass the file selection window and place filename directly in text entry area - but we are not finding a way to do this. How can this be accomplished? ...or perhaps it cannot be done?
