  • Where does a Quick-Time powered application store changes to the user interface?

    - by Luke
    I have downloaded an application written with the Quick Time library (for Windows 7). The application does not need an installation: just unzip it in a directory and run the program. It works, but I have a problem: the program allows the user to change a lot of values using its interface but does not have an option to reset them to their default values. What is more problematic is that when I exit the program and run it again, the interface still has the changed values. In the program directory there is no file that stores the changes done to the UI of the program. I suspect that Quick Time records these changes somewhere, but I can't find the right file. I have even deleted the application and re-unzipped it to another location - but the UI values still remain the same values changed by me!

  • loading a heightmap as texture in shader

    - by wtherapy
    I have a height map of 256x256, containing, foreach cell, not only height as a normal float value ( not 0-1 ) and also 2 gradient values ( for X and Y ), also as normal float values ( not 0-1 ). I have uploaded the texture via normal texture loading: glEnable( GL_TEXTURE_2D ); glGenTextures( 1, &m_uglID ); DEBUG_OUTPUT("Err %x\n", glGetError()); glBindTexture( GL_TEXTURE_2D , m_uglID ); DEBUG_OUTPUT("Err %x\n", glGetError()); glTexImage2D( GL_TEXTURE_2D, 0, GL_RGB32F, unW + 1, unH + 1, 0, GL_RGB, GL_FLOAT, pvBytes ); DEBUG_OUTPUT("Err %x\n", glGetError()); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_LINEAR); DEBUG_OUTPUT("Err %x\n", glGetError()); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_LINEAR); DEBUG_OUTPUT("Err %x\n", glGetError()); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); DEBUG_OUTPUT("Err %x\n", glGetError()); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); DEBUG_OUTPUT("Err %x\n", glGetError()); as a parenthesis, the debug output is: Err 500 Err 0 Err 0 Err 0 Err 500 Err 500 Err 0 Err 0 pvBytes is a 256x256 array of typedef struct _tGradientHeightCell { float v; float px; float py; } TGradientHeightCell, *LPTGradientHeightCell; then, m_ugl_HeightMapTexture = glGetUniformLocation(m_uglProgram, "TexHeightMap"); I load it via: glEnable(GL_TEXTURE_2D ); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D , pTexture->GetID()); glUniform1i(m_ugl_HeightMapTexture, 0); in shader, I just access it: uniform sampler2D TexHeightMap; vec4 GetVertCellParameters( uint i, uint j ) { return texture( TexHeightMap, vec2( i, j ) ); } vec4 vH00 = GetVertCellParameters( i, j ); My problem is that, when passing negative values in one of the values in TGradientHeightCell ( v, px, py ), the texture is corrupted. I need the values to be passed exact as I have them in memory. Any help appreciated.

  • Testing Django Inline ModelForms: How to arrange POST data?

    - by unclaimedbaggage
    Hi folks, I have a Django 'add business' view which adds a new business with an inline 'business_contact' form. The form works fine, but I'm wondering how to write up the unit test - specifically, the 'postdata' to send to self.client.post(settings.BUSINESS_ADD_URL, postdata) I've inspected the fields in my browser and tried adding post data with corresponding names, but I still get a 'ManagementForm data is missing or has been tampered with' error when run. Anyone know of any resources for figuring out how to post inline data? Relevant models, views & forms below if it helps. Lotsa thanks. MODEL: class Contact(models.Model): """ Contact details for the representatives of each business """ first_name = models.CharField(max_length=200) surname = models.CharField(max_length=200) business = models.ForeignKey('Business') slug = models.SlugField(max_length=150, unique=True, help_text=settings.SLUG_HELPER_TEXT) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) phone = models.CharField(max_length=100, null=True, blank=True) mobile_phone = models.CharField(max_length=100, null=True, blank=True) email = models.EmailField(null=True) deleted = models.BooleanField(default=False) class Meta: db_table='business_contact' def __unicode__(self): return '%s %s' % (self.first_name, self.surname) @models.permalink def get_absolute_url(self): return('business_contact', (), {'contact_slug': self.slug }) class Business(models.Model): """ The business clients who you are selling products/services to """ business = models.CharField(max_length=255, unique=True) slug = models.SlugField(max_length=100, unique=True, help_text=settings.SLUG_HELPER_TEXT) description = models.TextField(null=True, blank=True) primary_contact = models.ForeignKey('Contact', null=True, blank=True, related_name='primary_contact') business_type = models.ForeignKey('BusinessType') deleted = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) address_1 = models.CharField(max_length=255, null=True, blank=True) address_2 = models.CharField(max_length=255, null=True, blank=True) suburb = models.CharField(max_length=255, null=True, blank=True) city = models.CharField(max_length=255, null=True, blank=True) state = models.CharField(max_length=255, null=True, blank=True) country = models.CharField(max_length=255, null=True, blank=True) phone = models.CharField(max_length=40, null=True, blank=True) website = models.URLField(null=True, blank=True) class Meta: db_table = 'business' def __unicode__(self): return self.business def get_absolute_url(self): return '%s%s/' % (settings.BUSINESS_URL, self.slug) VIEWS: class Contact(models.Model): """ Contact details for the representatives of each business """ first_name = models.CharField(max_length=200) surname = models.CharField(max_length=200) business = models.ForeignKey('Business') slug = models.SlugField(max_length=150, unique=True, help_text=settings.SLUG_HELPER_TEXT) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) phone = models.CharField(max_length=100, null=True, blank=True) mobile_phone = models.CharField(max_length=100, null=True, blank=True) email = models.EmailField(null=True) deleted = models.BooleanField(default=False) class Meta: db_table='business_contact' def __unicode__(self): return '%s %s' % (self.first_name, self.surname) @models.permalink def get_absolute_url(self): return('business_contact', (), {'contact_slug': self.slug }) class Business(models.Model): """ The business clients who you are selling products/services to """ business = models.CharField(max_length=255, unique=True) slug = models.SlugField(max_length=100, unique=True, help_text=settings.SLUG_HELPER_TEXT) description = models.TextField(null=True, blank=True) primary_contact = models.ForeignKey('Contact', null=True, blank=True, related_name='primary_contact') business_type = models.ForeignKey('BusinessType') deleted = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) address_1 = models.CharField(max_length=255, null=True, blank=True) address_2 = models.CharField(max_length=255, null=True, blank=True) suburb = models.CharField(max_length=255, null=True, blank=True) city = models.CharField(max_length=255, null=True, blank=True) state = models.CharField(max_length=255, null=True, blank=True) country = models.CharField(max_length=255, null=True, blank=True) phone = models.CharField(max_length=40, null=True, blank=True) website = models.URLField(null=True, blank=True) class Meta: db_table = 'business' def __unicode__(self): return self.business def get_absolute_url(self): return '%s%s/' % (settings.BUSINESS_URL, self.slug) FORMS: class AddBusinessForm(ModelForm): class Meta: model = Business exclude = ['deleted','primary_contact',] class ContactForm(ModelForm): class Meta: model = Contact exclude = ['deleted',] AddBusinessFormSet = inlineformset_factory(Business, Contact, can_delete=False, extra=1, form=AddBusinessForm, )

  • Unexpected Html.EditorFor behavior in ASP.NET MVC 2

    - by NickLarsen
    I am getting some unexpected behavior from Html.EditorFor(). I have this controller: [HandleError] public class HomeController : Controller { [AcceptVerbs(HttpVerbs.Get)] public ActionResult Lister() { string[] values = { "Hello", "world", "!!!" }; return View(values); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Lister(string[] values) { string[] newValues = { "Some", "other", "values" }; return View(newValues); } } And this is my view which is intended to work for both of these: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<string[]>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Lister </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Lister</h2> <% using (Html.BeginForm()) { %> <% foreach (string value in Model) { %> <%= value %><br /> <% } %> <%= Html.EditorForModel() %> <input type="submit" value="Append Dashes" /> <% } %> </asp:Content> And the problem is that when the post back is made from the view, it hits the correct action, but the text boxes still show the original hello world data while the foreach loop outputs the new values. It feels like something in ASP.NET is overriding my model values from updating the text boxes and they are just displaying the same old values. I found this issue while trying to learn EditorFor with an IEnumerable.

  • Compression algorithm for IEEE-754 data

    - by David Taylor
    Anyone have a recommendation on a good compression algorithm that works well with double precision floating point values? We have found that the binary representation of floating point values results in very poor compression rates with common compression programs (e.g. Zip, RAR, 7-Zip etc). The data we need to compress is a one dimensional array of 8-byte values sorted in monotonically increasing order. The values represent temperatures in Kelvin with a span typically under of 100 degrees. The number of values ranges from a few hundred to at most 64K. Clarifications All values in the array are distinct, though repetition does exist at the byte level due to the way floating point values are represented. A lossless algorithm is desired since this is scientific data. Conversion to a fixed point representation with sufficient precision (~5 decimals) might be acceptable provided there is a significant improvement in storage efficiency. Update Found an interesting article on this subject. Not sure how applicable the approach is to my requirements. http://users.ices.utexas.edu/~burtscher/papers/dcc06.pdf

  • LINQ-to-SQL IN/Contains() for Nullable<T>

    - by Craig Walker
    I want to generate this SQL statement in LINQ: select * from Foo where Value in ( 1, 2, 3 ) The tricky bit seems to be that Value is a column that allows nulls. The equivalent LINQ code would seem to be: IEnumerable<Foo> foos = MyDataContext.Foos; IEnumerable<int> values = GetMyValues(); var myFoos = from foo in foos where values.Contains(foo.Value) select foo; This, of course, doesn't compile, since foo.Value is an int? and values is typed to int. I've tried this: IEnumerable<Foo> foos = MyDataContext.Foos; IEnumerable<int> values = GetMyValues(); IEnumerable<int?> nullables = values.Select( value => new Nullable<int>(value)); var myFoos = from foo in foos where nullables.Contains(foo.Value) select foo; ...and this: IEnumerable<Foo> foos = MyDataContext.Foos; IEnumerable<int> values = GetMyValues(); var myFoos = from foo in foos where values.Contains(foo.Value.Value) select foo; Both of these versions give me the results I expect, but they do not generate the SQL I want. It appears that they're generating full-table results and then doing the Contains() filtering in-memory (ie: in plain LINQ, without -to-SQL); there's no IN clause in the DataContext log. Is there a way to generate a SQL IN for Nullable types?

  • Django, want to upload eather image (ImageField) or file (FileField)

    I have a form in my html page, that prompts user to upload File or Image to the server. I want to be able to upload ether file or image.

  • Assigning static final int in a JUnit (4.8.1) test suite

    - by Dr. Monkey
    I have a JUnit test class in which I have several static final ints that can be redefined at the top of the tester code to allow some variation in the test values. I have logic in my @BeforeClass method to ensure that the developer has entered values that won't break my tests. I would like to improve variation further by allowing these ints to be set to (sensible) random values in the @BeforeClass method if the developer sets a boolean useRandomValues = true;. I could simply remove the final keyword to allow the random values to overwrite the initialisation values, but I have final there to ensure that these values are not inadvertently changed, as some tests rely on the consistency of these values. Can I use a constructor in a JUnit test class? Eclipse starts putting red underlines everywhere if I try to make my @BeforeClass into a constructor for the test class, and making a separate constructor doesn't seem to allow assignment to these variables (even if I leave them unassigned at their declaration); Is there another way to ensure that any attempt to change these variables after the @BeforeClass method will result in a compile-time error? Can I make something final after it has been initialised?

The thing is that the first index of this column is a unique primary key. So am I correct in assuming that a skip scan is the wrong thing to do here? Also, what kind of scan should it be doing? Should I do some more hinting for this query? EDIT: I should also point out that the query's where clause uses the columns in IDX_MBR_IDENTFN and no columns other than what's in that index. So as far as I can tell, I'm not skipping any columns.

  • New Perl user: using a hash of arrays

    - by Zach H
    I'm doing a little datamining project where a perl script grabs info from a SQL database and parses it. The data consists of several timestamps. I want to find how many of a particular type of timestamp exist on any particular day. Unfortunately, this is my first perl script, and the nature of perl when it comes to hashes and arrays is confusing me quite a bit. Code segment: my %values=();#A hash of the total values of each type of data of each day. #The key is the day, and each key stores an array of each of the values I need. my @proposal; #[drafted timestamp(0), submitted timestamp(1), attny approved timestamp(2),Organiziation approved timestamp(3), Other approval timestamp(4), Approved Timestamp(5)] while(@proposal=$sqlresults->fetchrow_array()){ #TODO: check to make sure proposal is valid #Increment the number of timestamps of each type on each particular date my $i; for($i=0;$i<=5;$i++) $values{$proposal[$i]}[$i]++; #Update rolling average of daily #TODO: To check total load, increment total load on all dates between attourney approve date and accepted date for($i=$proposal[1];$i<=$proposal[2];$i++) $values{$i}[6]++; } I keep getting syntax errors inside the for loops incrementing values. Also, considering that I'm using strict and warnings, will Perl auto-create arrays of the right values when I'm accessing them inside the hash, or will I get out-of bounds errors everywhere? Thanks for any help, Zach

  • how to remove duplicates but keep the same order?

    - by Ben Fossen
    I have a cell array in Matlab y = { 'd' 'f' 'a' 'g' 'g' 'a' 'w' 'h'} I use unique(y) to get rid of the duplicates but it rearranges the strings in alphabetica order >> unique(y) ans = 'a' 'd' 'f' 'g' 'h' 'w' Like this I want to remove the duplicates but keep the same order. I know I could write a function do do this but was wondering if there was a simpler way using unique to remove duplicates while keeping the same order just with the duplicates removed. I want it to return this >> unique(y) ans = 'd' 'f' 'a' 'g' 'w' 'h'

  • Remove duplicates and update IDs linked to nonduplicates

    - by colinr23
    I have two tables, tableA and tableB, linked through a locationID. TableA has descriptive survey info with each record from a different time (ie unique), while TableB has purely locational information. However, there are lots of duplicates in TableB, yet each has a unique locationID, which has an entry in TableA. I've found plenty posts about removing duplicates from TableB, but how can I update the locationIDs in TableA so they are linked to the unique locations in TableB once duplicates are removed... Help much appreciated!

  • populating one checkedlistbox with another (checkedlistbox)

    - by 8thWonder
    I am having difficulties populating a checkedlistbox (CLB) based on the selection(s) made in another. It should also be noted that I have a "Select All" checkbox at the top that checks/unchecks all of the items in the first CLB. Here's the code: Private Sub chkSelectAll_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles chkSelectAll.CheckedChanged For i As Integer = 0 To clb1.Items.Count - 1 clb1.SetItemChecked(i, chkSelectAll.Checked) Next End Sub Private Sub clb1_ItemCheck(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles clb1.ItemCheck Dim i As Integer = clb1.SelectedIndex For j As Integer = 0 To al_2.Count - 1 If i = -1 Then For k As Integer = 0 To al_2.Count - 1 If Not clb2.Contains(al_2(k).sDate) Then clb2.Items.Add(al_2(k).sDate) Else : k += 1 End If Next ElseIf (e.NewValue = CheckState.Checked And al_2(j).sName = al_1(i)) Then clb2.Items.Add(al_2(j).sDate) ElseIf (e.NewValue = CheckState.Unchecked And al_2(j).sName = al_1(i)) Then clbProdBkups.Items.Remove(al_2(j).sDate) End If Next End Sub The first CLB is populated with an arraylist of values on the button click event. Based on whatever is checked in the first CLB, corresponding values from an arraylist of structures should fill the second CLB. The following code partially works until the "Select All" checkbox is clicked at which point one of two things happens: If other values have been selected before "Select All" is checked, the second CLB is filled with the correct number of corresponding values BUT only those of the most recently selected item of the first CLB instead of all of corresponding values of all of the items that were not already selected. When "Select All" is unchecked, the most recently incorrect values are removed, everything in CLB 1 is unchecked but the values in CLB 2 that were selected before "Select All" was checked remain. If "Select All" is checked before anything else is selected, I get an "unable to cast object of type 'System.String' to type 'System.Windows.Forms.Control'" error that points to the following statement from the itemcheck event: If Not clb2.Contains(al_2(k).sDate) Then Any insights will be greatly appreciated. ~8th

  • How to represent and insert into an ordered list in SQL?

    - by Travis
    I want to represent the list "hi", "hello", "goodbye", "good day", "howdy" (with that order), in a SQL table: pk | i | val ------------ 1 | 0 | hi 0 | 2 | hello 2 | 3 | goodbye 3 | 4 | good day 5 | 6 | howdy 'pk' is the primary key column. Disregard its values. 'i' is the "index" that defines that order of the values in the 'val' column. It is only used to establish the order and the values are otherwise unimportant. The problem I'm having is with inserting values into the list while maintaining the order. For example, if I want to insert "hey" and I want it to appear between "hello" and "goodbye", then I have to shift the 'i' values of "goodbye" and "good day" (but preferably not "howdy") to make room for the new entry. So, is there a standard SQL pattern to do the shift operation, but only shift the elements that are necessary? (Note that a simple "UPDATE table SET i=i+1 WHERE i=3" doesn't work, because it violates the uniqueness constraint on 'i', and also it updates the "howdy" row unnecessarily.) Or, is there a better way to represent the ordered list? I suppose you could make 'i' a floating point value and choose values between, but then you have to have a separate rebalancing operation when no such value exists. Or, is there some standard algorithm for generating string values between arbitrary other strings, if I were to make 'i' a varchar? Or should I just represent it as a linked list? I was avoiding that because I'd like to also be able to do a SELECT .. ORDER BY to get all the elements in order.

  • How to return value using ajax

    - by Priyanka
    Hello. I have Ajax file in which code has written to accept values form user and then these values are taken in a Ajax function as follows: $(document).ready(function(){ $("#newsletterform").validate(); $('#Submit').click(function(){ var name = $('#newsletter_name').val(); var email = $('#newsletter_email').val(); sendValue(email,name); }); }); The function for paasing values and getting values from other file: function sendValue(str,name){ $.post( "newsletter/subscribe.php", //Ajax file { sendValue: str, sendVal: name }, function(data2){ $('#display').html(data2.returnValue); }, //How you want the data formated when it is returned from the server. "json" ); } and these values are passed to another file called "subscribe.php" in which insertion code to database is written and again I return the value to my first ajax function as follows: echo json_encode(array("returnValue"=$msg)); The msg is ging to contain my message to be displayed. But now, this works fine on localhost, I get the return values nad message properly but when I upload it on server this gives me an error as: data2 is null [Break on this error] $('#display').html(data2.returnValue); This only gives error for return value but insertion, sending mail functionality works fine. Please provide me with a good solution wherein I can be able to get back the return values without any error. Thanks in advance.

  • Does the order of columns matter in a group by clause?

    - by Jeff Meatball Yang
    If I have two columns, one with very high cardinality and one with very low cardinality (unique # of values), does it matter in which order I group by? Here's an example: select dimensionName, dimensionCategory, sum(someFact) from SomeFact f join SomeDim d on f.dimensionKey = d.dimensionKey group by d.dimensionName, -- large number of unique values d.dimensionCategory -- small number of unique values Are there situations where it matters?

  • Oracle : Identifying duplicates in a table without index

    - by user288031
    When I try to create a unique index on a large table, I get a unique contraint error. The unique index in this case is a composite key of 4 columns. Is there an efficient way to identify the duplicates other than : select col1, col2, col3, col4, count() from Table1 group by col1, col2, col3, col4 having count() 1 The explain plan above shows full table scan with extremely high cost, and just want to find if there is another way. Thanks !

  • how to set a fixed color bar for pcolor in python matplotlib?

    - by user248237
    I am using pcolor with a custom color map to plot a matrix of values. I set my color map so that low values are white and high values are red, as shown below. All of my matrices have values between 0 and 20 (inclusive) and I'd like 20 to always be pure red and 0 to always be pure white, even if the matrix has values that don't span the entire range. For example, if my matrix only has values between 2 and 7, I don't want it to plot 2 as white and 7 as red, but rather color it as if the range is still 0 to 20. How can I do this? I tried using the "ticks=" option of colorbar but it did not work. Here is my current code (assume "my_matrix" contains the values to be plotted): cdict = {'red': ((0.0, 1.0, 1.0), (0.5, 1.0, 1.0), (1.0, 1.0, 1.0)), 'green': ((0.0, 1.0, 1.0), (0.5, 1.0, 1.0), (1.0, 0.0, 0.0)), 'blue': ((0.0, 1.0, 1.0), (0.5, 1.0, 1.0), (1.0, 0.0, 0.0))} my_cmap = matplotlib.colors.LinearSegmentedColormap('my_colormap', cdict, 256) colored_matrix = plt.pcolor(my_matrix, cmap=my_cmap) plt.colorbar(colored_matrix, ticks=[0, 5, 10, 15, 20]) any idea how I can fix this to get the right result? thanks very much.
