  • How can I have a web link perform an action in a specific desktop application?

    - by John
    The specific situation is I have a .zip file that I want to open with a certain application. However, I don't want all ZIP files associated with that application. I think the answer is that instead of saying, "download this zip file, and open it with application X" I could have the browser basically go well my desktop application to go fetch it on its own (the same way directives like itunes: mailto: or aim: do things like launch the itunes store, add buddies, etc). Thoughts?

I want to be able to be able to draw only the bottom portion that would resemble an uppercase L. I'd like to be able to select a window of points from the GraphicsPath. Is there a handy way to do this without doing point interpolation?

  • Font advance calculation problem on Blackberry OS 5.0

    - by John
    I am currently working on my own implementation of a tab bar for a BlackBerry app, where each tab bar has a title that is right aligned (i.e. the last character in each should be the same distance from the right hand side of the screen). To work out where to draw the text I am using the following calculation: screen width - advance of title - indent. The font I am using is 'BBAlpha Sans' (height 28). Using BlackBerry OS 4.6 everything seems to be calculated properly and the text is aligned when I move between tabs, however I am finding that when I use OS 5.0 it doesn't calculate the advance properly and as a result the alignment is off by maybe 5 pixels or so. With the default font (also BBAlpha Sans, but height 24 - for OS 5.0 at least) it works fine in both versions.. but I don't necessarily always want to use the default font/size, so any ideas what could be going wrong? Is this a bug in the 5.0 API? Thanks. Code: public class TitleBarBackground extends Background { .. public void draw(Graphics graphics, XYRect rect) { graphics.pushRegion(rect); .. Font titleBarFont = FontFamily.forName("BBAlpha Sans").getFont(Font.PLAIN, 28); ... int textWidth = titleBarFont.getAdvance(title); graphics.drawText(title, rect.width - textWidth - TITLE_OFFSET, textYOffset); graphics.popContext(); } .. }

  • NHibernate - define where condition

    - by t.kehl
    Hi. In my application the user can defines search-conditions. He can choose a column, set an operator (equals, like, greater than, less or equal than, etc.) and give in the value. After the user clicks on a button and the application should do a search on the database with the condition. I use NHibernate and ask me now, what is the efficientest way to do this with NHibernate. Should I create a query with it like (Column=Name, Operator=Like, Value=%John%) var a = session.CreateCriteria<Customer>(); a.Add(Restrictions.Like("Name", "%John%")); return a.List<Customer>(); Or should I do this with HQL: var q = session.CreateQuery("from Customer where " + where); return q.List<Customer >(); Or is there a more bether solution? Thanks for your help. Best Regards, Thomas

  • Left Join works with table but fails with query

    - by Frank Martin
    The following left join query in MS Access 2007 SELECT Table1.Field_A, Table1.Field_B, qry_Table2_Combined.Field_A, qry_Table2_Combined.Field_B, qry_Table2_Combined.Combined_Field FROM Table1 LEFT JOIN qry_Table2_Combined ON (Table1.Field_A = qry_Table2_Combined.Field_A) AND (Table1.Field_B = qry_Table2_Combined.Field_B); is expected by me to return this result: +--------+---------+---------+---------+----------------+ |Field_A | Field_B | Field_A | Field_B | Combined_Field | +--------+---------+---------+---------+----------------+ |1 | | | | | +--------+---------+---------+---------+----------------+ |1 | | | | | +--------+---------+---------+---------+----------------+ |2 |1 |2 |1 |John, Doe | +--------+---------+---------+---------+----------------+ |2 |2 | | | | +--------+---------+---------+---------+----------------+ [Table1] has 4 records, [qry_Table2_Combined] has 1 record. But it gives me this: +--------+---------+---------+---------+----------------+ |Field_A | Field_B | Field_A | Field_B | Combined_Field | +--------+---------+---------+---------+----------------+ |2 |1 |2 |1 |John, Doe | +--------+---------+---------+---------+----------------+ |2 |2 |2 | |, | +--------+---------+---------+---------+----------------+ Really weird is that the [Combined_Field] has a comma in the second row. I use a comma to concatenate two fields in [qry_Table2_Combined]. If the left join query uses a table created from the query [qry_Table2_Combined] it works as expected. Why does this left join query not give the same result for a query and a table? And how can i get the right results using a query in the left join?

  • How to use Hibernate SchemaUpdate class with a JPA persistence.xml?

    - by John Rizzo
    I've a main method using SchemaUpdate to display at the console what tables to alter/create and it works fine in my Hibernate project: public static void main(String[] args) throws IOException { //first we prepare the configuration Properties hibProps = new Properties(); hibProps.load(Thread.currentThread().getContextClassLoader().getResourceAsStream("jbbconfigs.properties")); Configuration cfg = new AnnotationConfiguration(); cfg.configure("/hibernate.cfg.xml").addProperties(hibProps); //We create the SchemaUpdate thanks to the configs SchemaUpdate schemaUpdate = new SchemaUpdate(cfg); //The update is executed in script mode only schemaUpdate.execute(true, false); ... I'd like to reuse this code in a JPA project, having no hibernate.cfg.xml file (and no .properties file), but a persistence.xml file (autodetected in the META-INF directory as specified by the JPA spec). I tried this too simple adaptation, Configuration cfg = new AnnotationConfiguration(); cfg.configure(); but it failed with that exception. Exception in thread "main" org.hibernate.HibernateException: /hibernate.cfg.xml not found Has anybody done that? Thanks.

  • C++ How do I properly use getline for ifstream members.

    - by John
    Ok so I have a problem with getline. I have a file that contains a couple strings. I created it by myself and I have each string on a seperate line. Ex. textfile.txt Line 1 Line 2 Line 3 Line 4 //Little snip of code ifstream inFile("textfile.txt"); getline(inFile, string1); When I debug the program and ask it to print out string1 it shows that "Line 1\r" is saved into string1. I understand that it's from me actually hitting enter when I created the file. This problem causes my program to have a segmentation fault. I know my code works because if I use ofstream to write the file first and then i read it in, it works. So for my quesiton, is their anyway to use the getline function without it picking up the escape sequence \r? If i am not clear just let me know.

  • Opening response stream in silverlight

    - by John Maloney
    Hello, I am attempting to return a image from a server using Silverlight 3. The server returns the Response stream like this: context.Response.ContentType = imageFactory.ContentType imgStream.WriteTo(context.Response.OutputStream) imgStream.Close() context.Response.End() On the Silverlight client I am handling the stream like: Dim request As HttpWebRequest = result.AsyncState Dim response As HttpWebResponse = request.EndGetResponse(result) Dim responseStream As IO.Stream = response.GetResponseStream() I want to take that stream and open the browsers save dialog, one option I have explored is using the Html.Window.Navigate(New Uri("image url")) and this opened the correct browser default dialog but it is not an option because I need to send extended information(e.g. XML) to the server through the HttpRequest.Headers.Item and the Navigate doesn't allow this. How can I take a Response Stream and force the default browser Save dialog to appear from the Silverlight Application without using the Html.Window.Navigate(New Uri("image url"))?

  • Emacs How to redefine Shift-R for expected use

    - by John Bellone
    I've checked my elisp files to make sure that I do not have any bindings that contain Shift+R (and I have not found any). I expect SHIFT+R to print an uppercase character, but instead I get R R undefined inside of the Emacs command line. This is only in C/C++ major modes. Any suggestions? Update: Describing the key shows that it is undefined. How would I define it for the normal, expected use (capitalizing the letter R)?

  • Data model for timesheet to task and/or timesheet to project?

    - by John
    Let's say I want to make a simple project tracking system. A manager can create a project. Then he can create tasks for that project. Team members can record the hours they work for each task or for the project as a whole. Is the following design for the t_timesheet table a good idea? timesheet_id - primary key, autoincrement project_id - not null, foreign key constraint to t_project task_id - nullable, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal Or should I do something like this: timesheet_id - primary key, autoincrement task_id - not null, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal In the second option, I intend to always have a record in t_task labelled "miscellaneous items" with a foreign key to the relevant t_project record. Then I'll be able to track all hours for a project that aren't for any particular task. Are any of the ideas above good? What would be better?

  • Javascript Split: without losing character

    - by Rohan
    I want to split certain text using JavaSscript. The text looks like: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. 11:30 am Messaged user John Doe Now, I want to split the string into events. i.e.: 9:30 pm The user did action A. would be one event. I'm using RegEx for this: var split = journals.split(/\d*\d:/); Thing is, the first two characters are getting lost. The split appears like this: 30 pm The user did action A. How do I split so that the split maintains the first two/three characters (ie 9: or 10:) etc? Thanks!

  • Paypal Payflow pro library

    - by John Stewart
    I already have an express checkout integrated with my Codeigniter application. Now I want to integrate seamless paypal where I collect the CC information and pass it to Paypal (via backend) and once everything is approved, my application shows that to the user. All this with out ever going to Paypal's website. I know that Paypal gives a bunch of sample code but they have so many different products that advertise to do the same thing. Is there any wrapper library in PHP that I can use for handling all this? What sort of design decision is involved in migrating to such system? Would I need SSL certificates for this?
