• How to improve performance of opening Microsoft Word when automated from c#?

  - by Abdullah BaMusa

  I have Microsoft Word template that I automated filling it’s fields from my application, and when the user request print I open this template. but creating word application every time user request print after filling fields is very expensive and lead to some delay while opening the template, so I choose to cache the reference to Word then just open the new filled template. that solve the performance issue as opening file is less expensive than recreating Word each time, but this work while the user just close the document not the entire Word application which when happened my reference to Word become invalid and return with exception says: “The RPC server is unavailable” next time request opening template . I tried to subscribe to BeforClosing event but his trigger for Quitting Word as well as Closing documents. My question is how to know if the word is closing document or quit the entire application so I take the proper action, or any hint for another direction of thinking about improve performance of opening word template.

• Check through Javascript that page is loading something

  - by Lilitu88

  When the browser is loading something on a page you can see it in the status bar that it says "Waiting for..." or "Transfering..." etc. In firebug you can check in the net tab when something is being loaded and see when it stops. That is what I want. Is there a way for me to trigger an event when that happens ? Or to get the status of the page or something ? Any way for me to know when that changes ? I know I can do this easier if I use Ajax, but I can't since the page it's expecting an Excel report. Thanks

• better for-loop syntax for detecting empty sequences?

  - by Dmitry Beransky

  Hi, Is there a better way to write the following: row_counter = 0 for item in iterable_sequence: # do stuff with the item counter += 1 if not row_counter: # handle the empty-sequence-case Please keep in mind that I can't use len(iterable_sequence) because 1) not all sequences have known lengths; 2) in some cases calling len() may trigger loading of the sequence's items into memory (as the case would be with sql query results). The reason I ask is that I'm simply curious if there is a way to make above more concise and idiomatic. What I'm looking for is along the lines of: for item in sequence: #process item *else*: #handle the empty sequence case (assuming "else" here worked only on empty sequences, which I know it doesn't)

• MySQL Access in Php to a database created in C-Panel

  - by Rhys Drury

  Basically, i'm having trouble connecting to a mysql database using a php web page. I created the database in C-panel using the wizard i'm connecting like this $db_host = "localhost"; //your host Database address $db_username = "xxxx"; //your account username $db_pass = "xxxxx"; //your account password $db_name = "xxxxx"; //your database name @mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql"); @mysql_select_db("$db_name") or die ("no database"); But all my page seems to do is trigger the " could not connect to mysql" my page does have wordpress installed at the minute but I'm planning to get rid of it as I'm creating my site myself. I'm just baffled why it can't connect, because in Phpmyadmin ( a feature on C-panel) it says the database is in localhost.

• Focus stealing is evil.

  - by lunixbochs

  A quick Google search for solutions to Focus Stealing in Windows reveals two main result categories: People suggesting incomplete solutions involving the ForegroundLockTimeout registry entry (or TweakUI, which I believe simply changes the aforementioned registry entry), which isn't very effective. Incessant hordes of Windows users complaining about it. It's particularly annoying in two common scenarios: Something triggers a program to popup a dialog window in the background while a fullscreen app is focused, causing the fullscreen app to minimize. A window steals focus while you are typing, stealing all of your keystrokes. If you happen to press Space, Enter, or trigger a keyboard shortcut (like Y for Yes), it can cause completely undesirable outcomes. What creative solutions can be applied to fix this problem for either or both of these scenarios?

• How can I disable the F4 key from showing the items in a ComboBox

  - by Alex

  You might not know this, but pressing the F4 key on a ComboBox makes it's drop-down item list appear. I believe this is the default behavior on Windows. Does anyone know how to override this behavior in WPF (C#)? I know that overriding default behavior is generally seen as bad practice, however in this case I have a rugged-device that runs XP Embedded. It has a handful of prominent Function keys (F1-F6) that need to trigger different events. This works fine, however when focused over a ComboBox the events aren't triggered as the ComboBox drops down. I have tried catching the KeyDown event both on the form and on the ComboBox and listening for the F4 key, however it doesn't get this far as the key press must be handled at a lower level. Any ideas? Thanks.

  - by Alan Bennett

  hi guys. so i have this form and on it is a combo box populated from a database via a SQL method. and i have another form which allows us to maintain the database table etc. so i make a new instance of the second form doing: Form1 frm = new Form2; frm.show(); once i have done what ever i wanted to do on the second form and i close it, i need to somehow trigger an event or something which will refresh the combo box and the code behind it. i was thinking of some onchange or focus event for the whole form, the problem is i have 5 of these combo boxes and running all the SQL again. i also thought of passing somesort of variable thro but then i would still need an event for that. any ideals would be awesome

• Get/Set nested property values

  - by Daniel Deer

  I'll try to be more descriptive here. A Few Q's: using: var foo = new Foo() { Bar = new Bar() { Value = "Value" } }; var value = DataBinder.Eval(foo, "Bar.Value"); Or: This one It is possible to retrieve an internal nested property using property path syntax. Is there a way to set/trigger a nested property (a regular property not DependencyProperty) easily with some kind of simple mechanisms as described here? I want to acheive something like: string newValue = "Hello World!"; DataBinder.EvalSet(foo, "Bar.Value", NewValue); Is there any mechanism that support both property path (for nested objects) and XPATHs (if the objects are XPATH navigable of course) ? again, that supports get and set options. Thanks, DD

• Index for wildcard match of end of string

  - by Anders Abel

  I have a table of phone numbers, storing the phone number as varchar(20). I have a requirement to implement searching of both entire numbers, but also on only the last part of the number, so a typical query will be: SELECT * FROM PhoneNumbers WHERE Number LIKE '%1234' How can I put an index on the Number column to make those searchs efficient? Is there a way to create an index that sorts the records on the reversed string? Another option might be to reverse the numbers before storing them, which will give queries like: SELECT * FROM PhoneNumbers WHERE ReverseNumber LIKE '4321%' However that will require all users of the database to always reverse the string. It might be solved by storing both the normal and reversed number and having the reversed number being updated by a trigger on insert/update. But that kind of solution is not very elegant. Any other suggestions?

• Camel | Need for Scheduling console

  - by user1692063

  I am using camel 2.9.0 in my project. We have a number of routes divided into different camel contexts. Each camel context is bundled separately and deployed in Apache Karaf. Now the problem is divied into 2 parts: 1.) Each route is a scheduled route. Although using Quartz component, we are able to define a cron expressio in each route, we want a console where in we can trigger,stop any route and also put a cron expression to any route.(Scheduling a route through a web console is our main objective). 2.) Also we tried to configure the cron expression for each route through quartz.property. But if someone wants to change the cron expression at runtime in Apache Karaf, then we have to stop the bundle deployed and start in again. What can be done to change the value of cron expression at runtime. Any replies and help would be appreciable. Piyush

• Sharepoint UserProfileService

  - by user365984

  I've got a sharepoint site and a custom aspx portal, both under Windows Authentication. With the same machine, it happens that my sharepoint site returning me my current login, while my custom aspx returning me my domain admin account instead. Is there anyway that I could ensure both logins are the same? Otherwise, is there anyway to consume SPUserProfileService from a custom aspx portal? Mainly, I need to have the custom aspx portal to get sharepoint logon id. Nevertheless, i could still trigger AccessDenied.aspx in sharepoint to prompt for logins.

• How does undo/redo basically work on iPhone OS?

  - by mystify

  My app doesn't use Core Data yet. Is it true that I must use Core Data for undo/redo? And: How does the user do the undo/redo? I've never seen it in action, and never ever used it. Don't know how I should do it if I wanted to. There's no undo/redo button anywhere. Yet they say it has undo/redo. So how does the user trigger this?

• Javascript text Resize

  - by blackessej

  Without getting into the "should a text resizer be used or not" debate, I'd like some help with this...suffice to say that my clientele are from and older generation and may be sight impaired... My script isn't functioning, and I'm not sure why. It's not live yet, so here's what I'm working with: function fsize(size,unit,id){ var vfontsize = document.getElementById("#colleft"); if(vfontsize){ vfontsize.style.fontSize = size + unit; } } var textsize = 14; function changetextsize(up){ if(up){ textsize = parseFloat(textsize)+2; }else{ textsize = parseFloat(textsize)-2; } } I'm using onclick events to trigger the size changes. Thanks for your help!

• Prevent Erroneous Property Assignment

  - by Gordon

  Porting android applications to iphone applications always gives me the following pattern that I accidentally create: - (void) myFunc:(id)prop { self.property = property; } Which instead should be: - (void) myFunc:(id)prop { self.property = prop; } This always causes my program to quietly break because property gets reset to its existing value rather than being set to the new value, 'prop'. I cannot name the parameter 'prop' to 'property' since the compile complains that the parameter masks the instance variables visibility. Is there a good way to avoid this situation? There are no compiler warnings. Is there a way to make xcode prevent this? I cannot see very many situations where you would set a property to the value of its underlying instance variable (maybe to trigger a KVO binding?), but I don't see myself doing that in majority of cases. I understand the above code is synthetic and should be done with @synthesize, but I am just using it as a simplified example to illustrate my point.

• Layering of CSS with z-index

  - by Matt Hintzke

  I have a created a 3 circle venn diagram using pure CSS3 and each circle has a :hover event attached to it. I also have an image of an arrow which is pointing to the center of the venn diagram. I want the arrow to visually appear to be on top of the circles, so I put the z-index higher on the arrow than the circles. The problem now, is that the :hover event does not trigger on half of the venn diagram now because the arrow image is on top, which causes the hover to be on top of the arrow rather than the circle that I want it to be over. So is it possible to make an element have a high z-index visually but not programmatically?

• Ruby: having callbacks on 'attr' objects

  - by JP

  Essentially I'm wondering how to place callbacks on objects in ruby, so that when an object is changed in anyway I can automatically trigger other changes: class MyClass attr_reader :proxy def proxy=(string_proxy = "") begin @proxy = URI.parse("http://"+((string_proxy.empty?) ? ENV['HTTP_PROXY'] : string_proxy)) @http = Net::HTTP::Proxy.new(@proxy.host,@proxy.port) rescue @http = Net::HTTP end end end m = MyClass.new m.proxy = "myproxy.com:8080" p m.proxy # => <URI: @host="myproxy.com" @port=8080> # However changing m.proxy will not change the @http variable, as proxy= is not being called. # Desired functionality: m.proxy = nil # Now @http.class is Net::HTTP, not Net::HTTP::Proxy

• Controling CRT memory initialization

  - by Ofek Shilon

  Occasionally you meet bugs that are reproducible only in release builds and/or only on some machines. A common (but by no means only) reason is uninitialized variables, that are subject to random behaviour. E.g, an uninitialized BOOL can be TRUE most of the time, on most machines, but randomly be initialized as FALSE. What I wish I would have is a systematic way of flushing out such bugs by modifying the behaviour of the CRT memory initialization. I'm well aware of the MS debug CRT magic numbers - at the very least I'd like to have a trigger to turn 0xCDCDCDCD (the pattern that initializes freshly allocated memory) to zeros. I suspect one would be able to easily smoke out nasty initialization pests this way, even in debug builds. Am I missing an available CRT hook (API, registry key, whatever) that enables this? Anyone has other ideas to get there?

• font-smoothing not applied to buttons

  - by David

  I have used this snippet to prevent webkit from changing antialiasing when using CSS transforms: html{ -webkit-font-smoothing: antialiased; } This works fine for most cases, however I noticed some weirdness in chrome when playing around with Bootstrap using this HTML: <button class="btn btn-inverse">John Doe</button> <a class="btn btn-inverse">John Doe</a>? This is how it looks in OSX/Chrome: Fiddle: http://jsfiddle.net/hY2J7/. In fact, it seems that it is not applied to buttons at all. Is there a safer technique to trigger the same antialiasing in webkit for all elements?

• Hibernate one-to-one: getId() without fetching entire object

  - by Rob

  I want to fetch the id of a one-to-one relationship without loading the entire object. I thought I could do this using lazy loading as follows: class Foo { @OneToOne(fetch = FetchType.LAZY, optional = false) private Bar bar; } Foo f = session.get(Foo.class, fooId); // Hibernate fetches Foo f.getBar(); // Hibernate fetches full Bar object f.getBar().getId(); // No further fetch, returns id I want f.getBar() to not trigger another fetch. I want hibernate to give me a proxy object that allows me to call .getId() without actually fetching the Bar object. What am I doing wrong?

• jqGrid: Is it possible to commit a cell change when tabbing off instead of pressing Enter?

  - by The Matt

  I have a simple in-line edit in my grid, and I want to commit the change when the user tabs off the textbox. The default behavior of jqGrid forces the user to press 'Enter' to commit the change, but this is non-intuitive for our users. onSelectRow: function(id) { $(gridCoreGroups).editRow(id, true, undefined, function(response) { alert("hello world"); } } I've worked my way through the events provided, but they all happen as a result of the user pressing 'Enter', which I want to avoid. Is there something I can wire up that would trigger an action when the user tabs off this cell?

• Is it considered bad practice to have ViewModel objects hold the Dispatcher?

  - by stiank81

  My WPF application is structured using the MVVM pattern. The ViewModels will communicate asynchronously with a server, and when the requested data is returned a callback in the ViewModel is triggered, and it will do something with this data. This will run on a thread which is not the UI Thread. Sometimes these callbacks involve work that needs to be done on the UI thread, so I need the Dispatcher. This might be things such as: Adding data to an ObservableCollection Trigger Prism commands that will set something to be displayed in the GUI Creating WPF objects of some kind. I try to avoid the latter, but the two first points here I find to be reasonable things for ViewModels to do. So; is it okay to have ViewModels hold the Dispatcher to be able to Invoke commands for the UI thread? Or is this considered bad practice? And why?
