  • Weird behavior with windows startup C#

    - by FrieK
    Hi, I've created an application with the option to start on Windows startup. First I did this via the Registry, like this: private void RunOnStartup(bool RunOnStartup) { Microsoft.Win32.RegistryKey key = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", true); if (RunOnStartup) { key.SetValue(ProgramTitle, System.Windows.Forms.Application.ExecutablePath.ToString()); } else { key.DeleteValue(ProgramTitle, false); } } And this worked, but not correctly. It started the .exe but with the same behavior as it was a new one with the default 'config.xml' it needs. Which is obviously wrong. I did not manage to find out what was wrong, so I tried it differently: create a shortcut in the Startup folder. Couldn't go wrong I figured, I mean, it's just a shortcut right? I used this code: private void RunOnStartup(bool RunOnStartup) { string startup = Environment.GetFolderPath(Environment.SpecialFolder.Startup) + "\\"+ProgramTitle+".url"; if (RunOnStartup) { using (StreamWriter writer = new StreamWriter(startup)) { string app = System.Reflection.Assembly.GetExecutingAssembly().Location; writer.WriteLine("[InternetShortcut]"); writer.WriteLine("URL=file:///" + app); writer.WriteLine("IconIndex=0"); string icon = app.Replace('\\', '/'); writer.WriteLine("IconFile=" + icon); writer.Flush(); } } else { if (File.Exists(startup)) { File.Delete(startup); } } } And this worked as well, it started, but with the same behavior. So my question is, does anyone have any idea how this happens? Any help is much appreciated! Thanks

  • How do I pass a Yahoo Pipes item into a YQL query?

    - by Joe Shaw
    One common thing to want to do in the Yahoo Pipes YQL element is pass in a Pipes value to the YQL query. For example: select * from html.tostring where url='<someurl>' and xpath='//div[@id="foo"]' and you want to pass in a dynamic value for <someurl>. Let's say that it's an RSS feed item's URL called item.link. Attempting to simply replace the quoted someurl with item.link gives you this error: Invalid identifier item.link. me is the only supported identifier in this context How can I pass this value in?

  • Implementing Unowned relationship Google App Engine

    - by nwallman
    My question is more of a best practices question on how to implement unowned relationships with Google App Engine. I am using JDO to do my persistence and like recommended in the google docs I'm persisting my list of unowned relationships like so: @PersistenceCapable(identityType = IdentityType.APPLICATION) public class User implements Serializable, UserDetails { ... @Persistent private List<Key> groups; ... } Now I came across my predicament when I went to query that list of objects using they Key object. So when I get my list of group keys in order to actually return a list of Group objects I have to do a look up on that key to get the object. My question is what is the recommended way of doing a unowned look up on a model object? Should I have an instance of the PersistanceManagerFactory on my Model object so I can do a lookup? Should I have an instance of my GroupDAO object on my Model object so I can do a look up? Should I have a Utility to do this type of lookup? I'm new to this so I just want to know which is the best way to do this. Thanks.

  • IEnumerable not null but calling Count() results in Exception

    - by Draak
    I have code that's working beautifully on my development machine, but when deployed to the server is throwing null reference exception. So, I can't step through the code, but I've pinned down the culprit. But now I am puzzled. Here's the code. The question is below. Dim certs = From p In persons _ Select New Certificate( _ p.Value, _ New CertificateData.Seminar(thisEvent.Seminar.Name, _ thisEvent.StartDate.Value, _ thisEvent.EndDate.Value, _ thisEvent.Venue.City, _ thisEvent.Venue.State, _ New CertificateData.Instructor( _ staffMember.Name, _ staffMember.Titles, _ instrSignatPath))) _ With {.CertificateId = p.Key} lblMessage.Text = CStr(certs Is Nothing) lblMessage.Text = lblMessage.Text + "<br />" + CStr(certs.Count()) In the code above persons is a dictionary of custom class, and certs is of IEnumerable type. Now here's the quandary.. The first line that sets the label returns False, so certs is not null. But the second line throws an null reference exception. How is this possible?

  • Rapid spectral analysis of audio file using Python 2.6?

    - by Ephemeralis
    What I want to do is to have a subroutine that analyses every 200 milliseconds of a sound file which it is given and spits out the frequency intensity value (from 0 to 1 as a float) of a specific frequency range into an array which I later save. This value then goes on to be used as the opacity value for a graphic which is supposed to 'strobe' to the audio file. The problem is, I have never ventured into audio analysis before and have no clue where to start. I have looked pymedia and scipy/numpy thinking I would be able to use FFT in order to achieve this, but I am not really sure how I would manipulate this data to end up with the desired result. The documentation on the SpectrAnalyzer class of pymedia is virtually non-existant and the examples on the website do not actually work with the latest release of the library - which isn't exactly making my life easier. How would I go about starting this project? I am at a complete loss as to what libraries I should even be using.

  • Changing color of a row in dropdown list

    - by Judy
    is it possible to change "selector" color in drop-down list? <select name="select" style="background-color: #ff0000"> <option style="background-color: #ff0000" value="1">Red</option> <option style="background-color: #ffffff" value="2">Green</option> <option style="background-color: #0000ff" value="3">Blue</option> </select> I tried in above style but it didn't worked. I know with javascript getting document.getElementById('text').style.color='red' can set the color. But is it possible in html to set the colors?

What's the dealio? The host supports PHP, I use it to run a Wordpress blog and other things.

  • Oracle - Trigger to check constraint before insert

    - by user1816507
    i would like to create a simple trigger to check a stored variable from a table. if the value of the variable is '1', then approve the insertion else if the value of the variable is '2', then prompt error message.

  • starting .net application from command prompt is having issue when path is in SHORTNAME

    - by ioWint
    when we start our .net application using a double click on the explorer or from command prompt where your folder path is proper full name then there is no issue at all. But when you start it from command prompt with the path being a Shortname involving a ~ the application behaves weird. IF is entering condition though the condition evaluates to FALSE in quick watch. Accessing a value of a variable in quick watch and immediate window shows value. but when you use it to assign to another variable in code, it returns NULL / no value. another observation: when you attach Visual studio to debug the app, and when you go about "Set as next statement" visual studio is giving options to select which dll to work up on. i have never seen this prompt before!

When I run the first perl script in my local machine with the -wc command, it says that the syntax is OK. Help me please.

  • Default values for Content Taxonomy fields in Drupal

    - by lazysoundsystem
    I'm trying to set the default value for a Content Taxonomy field in a hook_form_alter, but can't pin down the necessary format. I've tried this and many variations: foreach (element_children($form) as $child) { // Set $default_value. if ($form[$child]['tids']) { // This, for Content Taxonomy fields, isn't working: $form[$child]['tids']['#default_value'] = array('value' => $default_value); dsm($form[$child]['tids']['#default_value']); } else { // This, for other fields, is working: $form[$child][0]['#default_value']['value'] = $default_value; } } Can anyone tell me what I'm missing?

  • Extending / changing how Zend_Search_Lucene searches

    - by Grant Collins
    Hi, I am currently using Zend_Search_Lucene to index and search a number of documents currently at around a 1000 or so. What I would like to do is change how the engine scores hits on a document, from the current default. Zend_Search_Lucene scores on the frequency of number of hits within a document, so a document that has 10 matches of the word PHP will score higher than a document with only 3 matches of PHP. What I am trying to do is pass a number of key words and score depending on the hits of those keywords. e.g. I pass 5 key words say,PHP, MySQL, Javascript, HTML and CSS that I search against the index. One document has 3 matches to those key words and one document has all 4 matches, the 4 matches scores the highest. The number of instances of those words in the document do not concern me. Now I've had a quick look at Zend_Search_Lucene_Search_Similarity however I have to confess that I am not sure (or that bright) to know how to use this to achieve what I am after. Is what I want to do possible using Lucene or is there a better solution out there?

  • sfConfig::get is not returning constants defined in app.yml

    - by morpheous
    I have an interesting problem. I am using Symfony 1.3.2. I have defined some constants in project/apps/frontend/config/app.yml and project/config/app.yml When I use the constant (correct spelling) in a piece of code like this $test=sfConfig::get('app_foobar'); the variable $test is assigned a null value. This is what I have checked so far: CHECK: cache files generated? (YES) CHECK: Do the cache files (config_app.yml.php) in the cache directory contain the constants defined in the app.yml file (YES) CHECK: Constant names used in the code matches the array keys found in config_app.yml? (YES) At this stage, I have run out of ideas. I dont want to supply a default value as a hack, because when I need to change the value of the constant, I will have to replace this in potentially hundreds of instances (too error prone). Is there anything that I have missed?. What could be causing this?

  • Retrieve messageId of email being sent using ezcomponents ezcMailComposer

    - by Ian
    I'm trying to retrieve the messageId for the email being sent. I've tried explicitly setting the messageId just before sending, like this: $mail->setHeader('messageId',ezcMailTools::generateMessageId('example.com')); I then return the messageId after sending, like this: return $mail->getHeader('messageId'); ... but the counter portion of the Id is always off by one. For example, the return value will be: [email protected] ... but the actual messageId will be: [email protected] Returning the messageId header value without explicitly setting it first returns a blank string. How can I retrieve this value?

  • Cache layer for MVC - Model or controller?

    - by Industrial
    Hi everyone, I am having some second thoughts about where to implement the caching part. Where is the most appropriate place to implement it, you think? Inside every model, or in the controller? Approach 1 (psuedo-code): // mycontroller.php MyController extends Controller_class { function index () { $data = $this->model->getData(); echo $data; } } // myModel.php MyModel extends Model_Class{ function getData() { $data = memcached->get('data'); if (!$data) { $query->SQL_QUERY("Do query!"); } return $data; } } Approach 2: // mycontroller.php MyController extends Controller_class { function index () { $dataArray = $this->memcached->getMulti('data','data2'); foreach ($dataArray as $key) { if (!$key) { $data = $this->model->getData(); $this->memcached->set($key, $data); } } echo $data; } } // myModel.php MyModel extends Model_Class{ function getData() { $query->SQL_QUERY("Do query!"); return $data; } } Thoughts: Approach 1: No multiget/multi-set. If a high number of keys would be returned, overhead would be caused. Easier to maintain, all database/cache handling is in each model Approach 2: Better performancewise - multiset/multiget is used More code required Harder to maintain Tell me what you think!

  • Does Postgresql varchar count using unicode character length or ASCII character length?

    - by bennylope
    I tried importing a database dump from a SQL file and the insert failed when inserting the string Mér into a field defined as varying(3). I didn't capture the exact error, but it pointed to that specific value with the constraint of varying(3). Given that I considered this unimportant to what I was doing at the time, I just changed the value to Mer, it worked, and I moved on. Is a varying field with its limit taking into account length of the byte string? What really boggles my mind is that this was dumped from another PostgreSQL database. So it doesn't make sense how a constraint could allow the value to be written initially.

  • Using Generics to return a literal string or from Dictionary<string, object>

    - by Mike
    I think I outsmarted myself this time. Feel free to edit the title also I could not think of a good one. I am reading from a file and then in that file will be a string because its like an xml file. But in the file will be a literal value or a "command" to get the value from the workContainer so <Email>[email protected]</Email> or <Email>[? MyEmail ?]</Email> What I wanted to do instead of writing ifs all over the place to put it in a generic function so logic is If Container command grab from container else grab string and convert to desired type Its up to the user to ensure the file is ok and the type is correct so another example is so <Answer>3</Answer> or <Answer>[? NumberOfSales ?]</Answer> This is the procedure I started to work on public class WorkContainer:Dictionary<string, object> { public T GetKeyValue<T>(string Parameter) { if (Parameter.StartsWith("[? ")) { string key = Parameter.Replace("[? ", "").Replace(" ?]", ""); if (this.ContainsKey(key)) { return (T)this[key]; } else { // may throw error for value types return default(T); } } else { // Does not Compile if (typeof(T) is string) { return Parameter } // OR return (T)Parameter } } } The Call would be mail.To = container.GetKeyValue<string>("[email protected]"); or mail.To = container.GetKeyValue<string>("[? MyEmail ?]"); int answer = container.GetKeyValue<int>("3"); or answer = container.GetKeyValue<int>("[? NumberOfSales ?]"); But it does not compile?

  • best way to prgram php and mysql query

    - by air
    most of times in our pages we need to print only 1 field value of table in loop. for example <?php for($i=1;$i<=mysql_num_rows($result);$i++) { echo $row['name']; $sql1="select industry from table_industry where profid='".$row['prof']."'"; $result1=mysql_query($sql1); $row1=mysql_fetch_array($result1); echo $row1['industry']; ?> } ?> above is one PHP code just for example where we think that $row['prof'] carry value of profession ID and we print profession of each person. for example we have 5000+ record in table and above loop will execute for 5000+ times what will be the best way to print value of industry field from table table_industry Same code which i write above ? any other php code suggestion for faster execution and less use of resources? Thanks
