  • Blogger issue with custom background images on Chrome and Safari

    - by hdx
    This is weird, the site in question is blog.andrebatista.info and it is a hosted at blogger.com. I'm trying to make the blogger template look the same as the one in my main website, www.andrebatista.info. For some reason if I go directly to the blog address Chrome and Safari fail to display all of my background images... all of them. However if I first go to www.andrebatista.info first and then go to the blog it renders just fine ?¿ The way I'm customizing it is by adding a link to my main site's stylesheet at the very end of the head tag on the blogger template. That stylesheet is displayed below: *{ margin:0; padding:0; border:0; } html,body { background:#064169 url(http://www.andrebatista.info/images/main_gradient_slice.jpg) repeat-x; font-family: Arial, "MS Trebuchet", sans-serif; font-size:18px; } #main_wrapper{ margin: 0 auto; width:1024px; } #header{ background: url(http://www.andrebatista.info/images/header.jpg); height:133px; border:none; margin:0; } #menu_wrapper{ background: url(http://www.andrebatista.info/images/menu.jpg); height:34px; overflow:hidden; } #menu_wrapper .menu_item{ color:white; float: left; border: 1 px solid red; height: 34px; padding-top:10px; text-align:center; width:100px; } #menu_wrapper .first{ padding-left:240px; float:left; width:100px; } #menu_wrapper .active,#menu_wrapper .menu_item:hover{ background-color:white; color:Teal; cursor: pointer; } #content_area_wrapper{ background: url(http://www.andrebatista.info/images/body_bg_slice.jpg) repeat-y; } #content_area{ min-height:524px; background: url(http://www.andrebatista.info/images/main_content_top.jpg) repeat-x; } #main_banner{ background: url(http://www.andrebatista.info/images/main_banner.jpg) no-repeat center center; width:662px; height:338px; margin: 0 auto; } #main_banner div{ color:white; padding-left:47px; padding-right:164px; padding-top:105px; } #text_area{ overflow:hidden; width:662px; margin:0 auto; padding:14px; } #contentList{ padding:0 20px 20px 20px; } #text_area .left{ width:50%; float:left; } #text_area .left{ width:50%; float:right; } #footer2{ background: url(http://www.andrebatista.info/images/footer.jpg); height:62px; } #footer{ background: url(http://www.andrebatista.info/images/footer.jpg); height:62px; } Any ideas on what I could be missing?

    - by Matt Huggins
    I have an object of type Hash that I want to loop over via hash.each do |key, value|. I would like to get the number of times I've been through the loop starting at 1. Is there a method similar to each that provides this (while still providing the hash key/value data), or do I need to create another counter variable to increment within the loop?

  • WPF items not visible when grouping is applied

    - by Tri Q
    Hi, I'm having this strange issue with my ItemsControl grouping. I have the following setup: <ItemsControl Margin="3" ItemsSource="{Binding Communications.View}" > <ItemsControl.GroupStyle> <GroupStyle> <GroupStyle.ContainerStyle> <Style TargetType="{x:Type GroupItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type GroupItem}"> <Expander> <Expander.Header> <Grid> <Grid.ColumnDefinitions > <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <TextBlock Text="{Binding ItemCount, StringFormat='{}[{0}] '}" FontWeight="Bold" /> <TextBlock Grid.Column="1" Text="{Binding Name, Converter={StaticResource GroupingFormatter}, StringFormat='{}Subject: {0}'}" FontWeight="Bold" /> </Grid> </Expander.Header> <ItemsPresenter /> </Expander> </ControlTemplate> </Setter.Value> </Setter> </Style> </GroupStyle.ContainerStyle> </GroupStyle> </ItemsControl.GroupStyle> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition /> </Grid.RowDefinitions> <TextBlock FontWeight="Bold" Text="{Binding Inspector, Converter={StaticResource NameFormatter}, StringFormat='{}From {0}:'}" Margin="3" /> <TextBlock Text="{Binding SentDate, StringFormat='{}{0:dd/MM/yy}'}" Grid.Row="1" Margin="3"/> <TextBlock Text="{Binding Message }" Grid.Column="1" Grid.RowSpan="2" Margin="3"/> <Button Command="vm:CommunicationViewModel.DeleteMessageCommand" CommandParameter="{Binding}" HorizontalAlignment="Right" Grid.Column="2">Delete</Button> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> In my ViewModel, I expose a CollectionViewSource named 'Communications'. I proceed to adding a grouping patter like so: Communications.GroupDescriptions.Add(new PropertyGroupDescription("Subject")); Now, the problem i'm experience is the grouping work fine, but I can't see any items inside the groups. What am I doing wrong? Any pointers would be much appreciated.

  • Installing assemblies to GAC with Windows Installer

    - by Andy Xufuris
    I am creating a Windwos Installer project just for the use of installing our third party assemblies into the gac of the users computer. The problem i am running into, is when i make an update to the assemblie and increment it's version number, i get an error saying: "Another version of this product is already installed. Installation of this version cannot continue..." I would have figured that windows installer would update the local machine with the new assemblie. Am i doing something wrong?

  • TeamCity build number versus Ant build number task

    - by jonny
    I have a build project that I run from TeamCity, now it takes the build.number from TeamCity. I want to be able to use the buildnumber task (Ant) which in my understanding when used, is supposed to change the value of build number property and increment it for next time. But it seems that I still get the build number from TeamCity. How can I use the build number from <buildnumber file="mybuild.number"/>?

  • Abstract Data Type: Any1 can help me this? thanks..

    - by Aga Hibaya
    Objectives: Implement the Abstract Data Type (ADT) List using dynamically allocated arrays and structures. Description A LIST is an ordered collection of items where items may be inserted anywhere in the list. Implement a LIST using an array as follows: struct list { int *items; // pointer to the array int size; // actual size of the array int count; // number of items in the array }; typedef struct list *List; // pointer to the structure Implement the following functions: a) List newList(int size); - will create a new List and return its pointer. Allocate space for the structure, allocate space for the array, then initialize size and count, return the pointer. b) void isEmpty(List list); c) void display(List list); d) int contains(List list, int item); e) void remove(List list, int i) ; f) void insertAfter(List list,int item, int i); g) void addEnd(List list,int item) - add item at the end of the list – simply store the data at position count, then increment count. If the array is full, allocate an array twice as big as the original. count = 5 size = 10 0 1 2 3 4 5 6 7 8 9 5 10 15 20 30 addEnd(list,40) will result to count = 6 size = 10 0 1 2 3 4 5 6 7 8 9 5 10 15 20 30 40 h) void addFront(List list,int item) - shift all elements to the right so that the item can be placed at position 0, then increment count. Bonus: if the array is full, allocate an array twice as big as the original. count = 5 size = 10 0 1 2 3 4 5 6 7 8 9 5 10 15 20 30 addFront(list,40) will result to count = 6 size = 10 0 1 2 3 4 5 6 7 8 9 40 5 10 15 20 30 i) void removeFront(List list) - shift all elements to the left and decrement count; count = 6 size = 10 0 1 2 3 4 5 6 7 8 9 40 5 10 15 20 30 removeFront(list) will result to count = 5 size = 10 0 1 2 3 4 5 6 7 8 9 5 10 15 20 30 j) void remove(List list,int item) - get the index of the item in the list and then shift all elements to the count = 6 size = 10 0 1 2 3 4 5 6 7 8 9 40 5 10 15 20 30 remove(list,10) will result to count = 5 size = 10 0 1 2 3 4 5 6 7 8 9 40 5 15 20 30 Remarks

  • Doctrine_Query update with float value

    - by YS-PRO
    I need to increment User's balance, so I do: Doctrine_Query::create()->from('User')->update('balance', 'balance + 0.15')->execute(); And I got an error "Unknown component alias 0". I think its because of 0.15 So how can I update (using DQL) balance without additional SELECT queries to User's table to fetch his balance, calculate new balance and do query like Doctrine_Query::create()->from('User')->update('balance', '?', $new_balance)->execute();

  • Negative Primary Keys

    - by bjax
    Are there any repercussions using Negative Primary Keys for tables (Identity Increment -1, Identity Seed -1 in SQL Server 2005)? The reason for this is we're creating a new database to replace an existing one. There are similar tables between the two databases and we'd like the "source" of the information to be transparent to our applications. The approach is to create views that unions tables from both databases. Negative PKs ensures the identities don't overlap.

  • Windows batch file timing bug

    I've used %time% for timing previously - at least I think I have. I have this weird IF NOT "%1" == "" ( echo Testing: %1 echo Start: %time% sqlcmd -S MYSERVER -i test_import_%1.sql -o "test_%1%.log" sleep 3 echo End: %time% ) I run this, and it prints: Testing: pm Start: 13:29:45.30 End: 13:29:45.30 In this case, my sql code is failing (different reason), but I figure the sleep 3 should make the time increment by 3 at least. Any ideas? tx, tff

  • how do i know how many clients are calling my WCF service function

    - by ZhengZhiren
    i am writing a program to test WCF service performance in high concurrency circumstance. On client side, i start many threads to call a WCF service function which returns a long list of data object. On server side, in that function called by my client, i need to know the number of clients calling the function. For doing that, i set a counter variable. In the beginning of the function, i add the counter by 1, but how can i decrease it after the funtion has returned the result? int clientCount=0; public DataObject[] GetData() { Interlocked.Increment(ref clientCount); List<DataObject> result = MockDb.GetData(); return result.ToArray(); Interlocked.Decrement(ref clientCount); //can't run to here... } i have seen a way in c++. Create a new class named counter. In the constructor of the counter class, increase the variable. And decrease it in the destructor. In the function, make a counter object so that its constructor will be called. And after the function returns, its destructor will be called. Like this: class counter { public: counter(){++clientCount; /* not simply like this, need to be atomic*/} ~counter(){--clientCount; /* not simply like this, need to be atomic*/} }; ... myfunction() { counter c; //do something return something; } In c# i think i can do so with the following codes, but not for sure. public class Service1 : IService1 { static int clientCount = 0; private class ClientCounter : IDisposable { public ClientCounter() { Interlocked.Increment(ref clientCount); } public void Dispose() { Interlocked.Decrement(ref clientCount); } } public DataObject[] GetData() { using (ClientCounter counter = new ClientCounter()) { List<DataObject> result = MockDb.GetData(); return result.ToArray(); } } } i write a counter class implement the IDisposable interface. And put my function codes into a using block. But it seems that it doesn't work so good. No matter how many threads i start, the clientCount variable is up to 3. Any advise would be appreciated.

  • How to generate a transaction number?

    I was thinking of formatting it like this TYYYYMMDDNNNNNNNNNNX (1 character + 19 digits) Where T is type YYYY is year MM is month DD is day N is sequencial number X is check digit The problem is, how do I generate the sequencial number? since my primary key is not an auto increment integer value, if it was i would use that, but its not. EDIT can I have the sequencial number resets itself after 1 day (24hours). P201012080000000001X <-- first transaction of 2010/12/08 P2010120810000000002X <--- second transaction of 2010/12/08 P201012090000000001X <--- First transaction of 2010/12/09 (X is the check digit)
