  • How to add a layer to a menuitem image

    - by alexander
    I have a menuitem with an image. I want to add half-transparent layer to that image. private void menuItem1_Paint(object sender, PaintEventArgs e) { using (SolidBrush brush = new SolidBrush(Color.FromArgb(128, SystemColors.ActiveCaption))) { e.Graphics.FillRectangle(brush, e.ClipRectangle); } } My problem is = I don't know clientrectangle of that image. e.ClipRectangle - it fills whole menuitem. I want to fill only image. How ? Is there another way, maybe ?

  • PostgreSQL: keep a certain number of records in a table

    - by Alexander Farber
    Hello, I have an SQL-table holding the last hands received by a player in card game. The hand is represented by an integer (32 bits == 32 cards): create table pref_hand ( id varchar(32) references pref_users, hand integer not NULL check (hand > 0), stamp timestamp default current_timestamp ); As the players are playing constantly and that data isn't important (just a gimmick to be displayed at player profile pages) and I don't want my database to grow too quickly, I'd like to keep only up to 10 records per player id. So I'm trying to declare this PL/PgSQL procedure: create or replace function pref_update_game(_id varchar, _hand integer) returns void as $BODY$ begin delete from pref_hand offset 10 where id=_id order by stamp; insert into pref_hand (id, hand) values (_id, _hand); end; $BODY$ language plpgsql; but unfortunately this fails with: ERROR: syntax error at or near "offset" because delete doesn't support offset. Does anybody please have a better idea here? Thank you! Alex

  • Python interpreter invocation with "-c" and indentation issues

    - by alexander
    I'm trying to invoke Python using the "-c" argument to allow me to run some arbitrary python code easily, like this: python.exe -c "for idx in range(10): print idx" Now this code works fine, from within my batch file, however, I'm running into problems when I want to do anything more than this. Consider the following Python code: foo = 'bar' for idx in range(10): print idx this would then give you 0-9 on the stdout. However, if I collapse this into a single line, using semicolons as delimiters, to get the following: foo = 'bar';for idx in range(10): print idx and try to run it using python.exe -c it get a SyntaxError raised: C:\Python>python.exe -c "foo = 'bar';for idx in range(10): print idx" File "<string>", line 1 foo = 'bar';for idx in range(10): print idx ^ SyntaxError: invalid syntax Anyone know how I can actually use this without switching to a separate .py file?

  • How to access a website's url programmatically from within the page

    - by Jeff
    For work, I am working on a site that has a feature that lets users make custom instances of the site depending on who they want to show it to. So if they want to show their potential employer a little bit about themselves, they can send them a custom url, that has a uid on the end of it that tells the database what to show and what not to when the site is loaded up. Now, I need to be able to take the value that is on the end of the url, this unique uid that corresponds with their preferences in the db, accessable on run time. Meaning that when someone types in this custom url, I need to be able to show the name of the person whose portfolio is being viewed BEFORE password authentication takes place... If I could get the URL, I suppose I could parse through it to find the necessary UID...but how do I get the url? Maybe I am just missing something here, but if anyone has any thoughts or ideas, it would be appreciated!! Thanks

  • A 4-byte Unsigned Int for Sql Server 2008?

    - by Jeff Meatball Yang
    I understand there are multiple questions about this on SO, but I have yet to find a definitive answer of "yes, here's how..." So here it is again: What are the possible ways to store an unsigned integer value (32-bit value or 32-bit bitmap) into a 4-byte field in SQL Server? Here are ideas I have seen: 1) Use a -1*2^31 offset for all values Disadvantages: need to perform math on the values before reading/writing/aggregating. 2) Use 4 tinyint fields Disadvantages: need to concatenate values to perform any operations 3) Use binary(4) Disadvantages: actually uses 4 + 2 bytes of space

  • Practical non-image based CAPTCHA approaches?

    - by Jeff Atwood
    It looks like we'll be adding CAPTCHA support to Stack Overflow. This is necessary to prevent bots, spammers, and other malicious scripted activity. We only want human beings to post or edit things here! We'll be using a JavaScript (jQuery) CAPTCHA as a first line of defense: http://docs.jquery.com/Tutorials:Safer_Contact_Forms_Without_CAPTCHAs The advantage of this approach is that, for most people, the CAPTCHA won't ever be visible! However, for people with JavaScript disabled, we still need a fallback and this is where it gets tricky. I have written a traditional CAPTCHA control for ASP.NET which we can re-use. However, I'd prefer to go with something textual to avoid the overhead of creating all these images on the server with each request. I've seen things like.. ASCII text captcha: \/\/(_)\/\/ math puzzles: what is 7 minus 3 times 2? trivia questions: what tastes better, a toad or a popsicle? Maybe I'm just tilting at windmills here, but I'd like to have a less resource intensive, non-image based <noscript> compatible CAPTCHA if possible. Ideas?

  • Popular open source projects using Zend Framework

    - by Alexander
    Hello, I am trying to find any open source project based on Zend Framework. Something well written and as popular as Wordpress or Drupal to see actual benefits of ZF as well as possibly use it as an example. The only 'showcase' I managed to find is http://framework.zend.com/wiki/pages/viewpage.action?pageId=14134. But this list looks confusing as for the 'official' PHP framework. The same is about ZF statistics by numbers (http://framework.zend.com/about/numbers) - 10 million downloads against 400 actual projects which is less than 500 examples in the user guide... Also Yahoo chose Symfony for their bookmarks service not ZF... Am I missing something? Thank you!

  • Is there a way to define a List<> of two elements string array?

    - by Alexander Prokofyev
    I want to build two-dimentional array of strings where length of one dimention is 2. Similar to this string[,] array = new string[,] { {"a", "b"}, {"c", "d"}, {"e", "f"}, {"g", "h"} } Doing List<string[]> list = new List<string[]>(); list.Add(new string[2] {"a", "b"}); list.Add(new string[2] {"c", "d"}); list.Add(new string[2] {"e", "f"}); list.Add(new string[2] {"g", "h"}); list.ToArray(); gives me string[][] but not string[,] array. Just curious, is there some trick to build dynamically string[,] array somehow?

  • XSLT: moving a grouping html elements into section levels

    - by Jeff
    Hello there, I'm trying to write an XSLT that organizes an HTML file into different section levels depending on the header level. Here is my input: <html> <head> <title></title> </head> <body> <h1>HEADER 1 CONTENT</h1> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <h2>Header 2 CONTENT</h2> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> </body> </html> I'm working with a fairly simple structure at the moment so this pattern will be constant for the time-being. I need an output like this... <document> <section level="1"> <header1>Header 1 CONTENT</header1> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <section level="2"> <header2>Header 2 CONTENT</header2> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> </section> </section> </document> I had been working with this example: Stackoverflow Answer However, I cannot get it to do exactly what I need. I'm using Saxon 9 to run the xslt within Oxygen for dev. I'll be using a cmd/bat file in production. Still Saxon 9. I'd like to handle up to 4 nested section levels if possible. Any help is much appreciated! I need to append onto this as I've encountered another stipulation. I probably should have thought of this before. I'm encountering the following code sample <html> <head> <title></title> </head> <body> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <h1>Header 2 CONTENT</h1> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> </body> </html> As you can see, the <p> is a child of <body> while in my first snippet, <p> was always a child of a header level. My desired result is the same as above except that when I encounter <p> as a child of <body>, it should be wrapped in <section level="1">. <document> <section level="1"> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> </section> <section level="1"> <header1>Header 2 CONTENT</header1> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> </section> </document>

  • NotApplicable marker with display pattern

    - by Jeff Barger
    Ok, so I'm pretty new to Cocoa, especially Bindings, but here's what I'm trying to do. I've got a Core Data model consisting of two entities: Category and Item. Category has a to-many relationship to Item called children, and Item has a relationship to Category called parent. Item has two attributes that Category does not have: quantity and desiredQuantity. What I'd like to do is display the tree in an NSOutlineView with two columns. One column is bound to the name of either the Category or the Item. I want to the second column to display something along the lines of 2 of 5 for the Item rows and nothing at all for the Category rows. When I use a display pattern, the Category rows end up showing of I noticed that if I don't use a display pattern for the second column, and instead just bind its Value to either the quantity or the desiredQuantity, the Category rows show nothing; its only if I try to use the display pattern. How can I make it display nothing for the Category rows and still use the display pattern? Or can I? Edit: I guess I didn't explain what the NotApplicable marker has to do with anything - Category does have properties for quantity and desiredQuantity, but they just return NSNotApplicableMarker.

  • aspnet_regsql questions and users and role

    - by Alexander
    I spend quite some hours banging my head against the wall trying to set up the aspnet membership / roles tables in my SQL server database instead of having them exist inside the App_Code/ASPNETDB.MDF file because that file wasn't working correctly on my host. I eventually figured out the problem by following Scott's gu here and was able to resolve it by running the aspnet_regsql.exe utility and creating a connection string for LocalSqlServer. The ridiculous part about it is that after running the aspnet_regsql and upload my database to my webhost all of my users and role that I have already created is gone. The user, membership, role, etc is gone. I can't populate this using the Web Site Administration Tool as it's not visual studio now. So what is the easiest way to populate the user, role, etc to my SQL Server as I now have dbo.aspnet_Application, dbo.aspnet_Paths, dbo.aspnet_Roles, etc...etc...

  • Changing printer preferences in Windows programmatically

    - by Andrew Alexander
    I've written a script that installs several printers for a new user. I want to change the settings on some of these so that they can print on both sides of the page. I BELIEVE this involves modifying an attribute with printui, however it might need VB script or possibly another .NET language (I'd either use VB, C# or IronPython). I can add a comment to a given printer, but how do I select preferences and modify them? Pseudocode would look like this: printui.exe /n printername /??? [how to change quality desired] OR calls to the relevant Windows API.

  • What changed in the DataGrid that means it won't work anymore?

    - by Jeff Yates
    I have a Silverlight app with a DataGrid containing some custom columns and all was working well. Then I updated to Silverlight 3 tools for VS 2008 SP1 and rebuilt it. Now it has the following problems: Rows aren't added when the collection is modified. The ItemsSource property is (and always has been) set to an ObservableCollection instance, which notifies when its contents change. This worked fine for Silverlight 2. However, in Silverlight 3 to get this working at all, I now have to null and then re-set ItemsSource - this seems like I'm hiding a bigger issue but I can't work out what that might be. I cannot select a row or a cell anymore. If I'm lucky, I can select one whole row before it stops working. I can't edit anything. I suspect this is related to the previous point. I'll post some source when I am able, but first I have to strip it down to the bare minimum. In the meantime, I was hoping someone might have some idea of what may be going on here. My gut feeling on the second two points is that my bindings are no longer working, but that's just a guess and if it is the case, I have no idea which ones. Thanks for any help anyone might be able to provide. Update So, I finally reduced my problem down to a simple works/doesn't work comparison. The problem seems to occur if I override Equals in my element type. As soon as I do that, something happens strangely in the ObservableCollection that contains that type, it seems, and my application breaks. To make it more interesting, there is a check to make sure that duplicate items don't even get close to being added to the collection. I don't exactly know why ObservableCollection needs to compare equality when inserting items (the stack trace indicates it is using IndexAt) but this seems to cause the issue. So, any thoughts?

  • Silverlight Image Data Binding

    - by Alexander
    I am new to Silverlight, and have an issue with binding. I have a class ItemsManager, that has inside its scope another class Item. class ItemsManager { ... class Item : INotifyPropertyChanged { ... private BitmapImage bitmapSource; public BitmapImage BitmapSource { get { return bitmapSource; } set { bitmapSource = value; if(PropertyChanged != null )PropertyChanged("BitmapSource") } } } } I do the following in code to test binding: { ItemsManager.Instance.AddItem("123"); //Items manager started downloading item visual //part (in my case bitmap image png) Binding b = new Binding("Source"); b.Source = ItemsManager.Instance.GetItem("123").BitmapSource; b.BindsDirectlyToSource = true; Image img = new Image(); img.SetBinding(Image.SourceProperty, b); img.Width = (double)100.0; img.Height = (double)100.0; LayoutRoot.Children.Add(img); } Once image is loaded, image doesn't appear. Though, if I set directly after image has been loaded its source, it displays well. I also noticed that PropertyChanged("BitmapSource") never fires, because PropertyChanged is null, like Image never binded to it. I am looking forward to hearing from you!
