  • Deployment of SQL Server: installing a second instance?

    - by Workshop Alex
    Simple problem. I'm working on a Delphi 2007/WIN32 application which now uses MS Access as simple data store. I have to modify it to support SQL Server Express, which is easy. These modifications are working so the application can be deployed using either SQL Server or MS Access. (Whatever the user prefers.) I did consider deploying the whole application together with the SQL Compact but this is not practicak. Using SQL Server Express 2008 instead of 2005 is an option, but also has a few nasty side-effects which we don't want to resolve for now. The problem is deploying the whole project. The installation with SQL Server would need a quiet installation so the user won't notice it. SQL Server is mentioned in the documentation so they know it's there. We just don't want to bother them with technical issues. In most cases, such an installation will go just fine. But what if the user already has an SQL Server (2005) installation which is used for something else? Personally, I would prefer to just install a second instance of SQL Server on their system so it won't conflict with the other installation. (Thus, if they uninstall the other app, the SQL instance will just stay installed.) While SQL Server 2005 and 2008 can be installed on the same system simply by using two different names for the instance, I wonder if it's also possible to install SQL Server 2005 twice on a single system to get two instances. And if possible, how?

  • How to cancel a touch sequence

    - by Alex
    I have an UIImage view that responds to touch events. I want to cancel the touch sequence if the touch goes outside of certain bounds. How can I do that? I know that I can inspect the coordinates of the touch object, what I don't know is how to cancel the sequence. I don't see any event in the API that allows for that.

  • Is there an easy way to replace a deprecated method call in Xcode?

    - by Alex Basson
    So iOS 6 deprecates presentModalViewController:animated: and dismissModalViewControllerAnimated:, and it replaces them with presentViewController:animated:completion: and dismissViewControllerAnimated:completion:, respectively. I suppose I could use find-replace to update my app, although it would be awkward with the present* methods, since the controller to be presented is different every time. I know I could handle that situation with a regex, but I don't feel comfortable enough with regex to try using it with my 1000+-files-big app. So I'm wondering: Does Xcode have some magic "update deprecated methods" command or something? I mean, I've described my particular situation above, but in general, deprecations come around with every OS release. Is there a better way to update an app than simply to use find-replace?

  • WPF: Change padding depending of container ?

    - by Alex Ilyin
    I have UserControl named MyUserControl, and another UserControl named MyContainer. I want MyUserControl to have padding 10 if it is placed inside MyContainer and 15 otherwise. Shortly, I want <MyContainer> <MyUserControl> Hello </MyUserControl> </MyContainer> to look like <MyContainer> <UserControl Padding="10"> Hello </UserControl> <MyContainer> and <MyUserControl> Hello </MyUserControl> to look like <UserControl Padding="15"> Hello </UserControl>

  • Dump to CSV/Postgres memory

    - by alex
    I have a large table (300 million lines) that I would like to dump to a csv - I need to do some processing that cannot be done with SQL. Right now I am using Squirrel as a client, and it does not apparently deal very well with large datasets - at least as far as I can tell from my own (limited) experience. If I run the query on the actual host, will it use less memory? Thanks for any help.

  • Is this text wrapping technique possible in CSS and jQuery?

    - by alex
    I have built a sliding text thing for a website. http://www.solomonadventures.com/~new/adventure-tours/seafari-tours/ The background contains the menu (on the right hand side), and when it originally loads, I have placed an element to make the text look like it is wrapping around the menu. Now, I have a sliding text thing I was asked to implement. The buttons to use it are currently in the top left corner. My question is, when I slide the content down, am I able to somehow make the text still wrap around it? This is all I have thought of so far (all with trade offs) Make the text appear beneath the menu - no need to wrap Make the text as narrow to the beginning of the menu - no need to wrap Manually place placeholders in the text that make it line break so it appears to wrap - not elegant (site uses a CMS too) Is there any jQuery selector I could write that would allow me to select the paragraph from top (once slid to the top) or the top most text node (so I could do an after() to place a new placeholder element to force it to wrap?) Any other solutions? Many thanks.

  • How to maintain fixed size of C variable types over different machines?

    - by Alex
    I've all this kind of functions. ssize_t fuc1(int var1, void *buf, size_t count); int func2(char *charPtr, int mode, int dev); short func3( long var2); problem is that data types in C has different sizes when compiled on different machines(64bit & 32bit). This is true for even void*. For some reasons. I need to ensure that these sizes all are same on every machine(64bit & 32bit). So, how should I modify these ?

  • What is a practical use for a closure in JavaScript?

    - by alex
    I'm trying my hardest to wrap my head around JavaScript's closures. I get that by returning an inner function, it will have access to any variable defined in it's immediate parent. Where would this be useful to me? Perhaps I haven't quite got my head around it yet. Most of the examples I have seen online don't provide any real world code, just vague examples. Can someone show me a real world use of a closure? Is this one, for example? var warnUser = function (msg) { var calledCount = 0; return function() { calledCount++; alert(msg + '\nYou have been warned ' + calledCount + ' times.'); }; }; var warnForTamper = warnUser('You can not tamper with our HTML.'); warnForTamper(); warnForTamper(); Thanks

  • Save phone calls data in a DB?

    - by Alex
    How would you save this data on a database: An user can make phone calls (id, date, hour, duration, outcome). The "outcome" can be, for example, to recall the client on another day (so I have to save the date, the hour, etc of this "future" call). How would you manage this data on a db? At the moment i have only a "Call" table.

  • CSS with Aligned LI within a UL

    - by Alex
    I am trying to have some LIs within a UL align left, right, and center within a page. For the life of me, I can't figure out how to keep something "centered" on the same line as a left and right aligned LI. <style> ul { margin:1em 0; padding:0 } ul li{ display:inline-block; white-space:nowrap; margin:5px } ul li.left{ float: left; text-align:left; } ul li.center{ float:left; text-align: center; } ul li.right{ float: right; text-align:right; } </style> <ul> <li class="left">left</li> <li class="center">center</li> <li class="right">right</li> </ul> <ul> <li class="left">left</li> <li class="right">right</li> </ul> <ul> <li class="left">left</li> </ul> Can anyone help? BTW, I've trying to avoid DIVs. Thanks!

  • LinkButton child controls render

    - by Alex
    Hi. I want to have a LinkButton that adds 'span' tag around the text. protected override void Render(HtmlTextWriter writer) { Text = String.Concat("<span>", Text, "</span>"); base.Render(writer); } It's works perfectly, but only if I add text like this: <cc:TestLinkButton ID="TestLinkButton" runat="server" Text="SomeText"> </cc:TestLinkButton> If I want to add some image I will write something like this: <cc:TestLinkButton ID="LinkButton1" runat="server"> <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/icon_holiday.png" BorderWidth="0" /> SomeText </cc:TestLinkButton> In this case Text property will be empty, because actualy "SomeText" is child control property. So question is is how to add tag around child controls.

  • Validating forms with regex in codeigniter

    - by Alex
    How can I validate a form using regex in codeiginiter. I'd like to check the input against: ^([0-1][0-9]|[2][0-3]):([0-5][0-9])$ I'm assuming the best way is in some sort of callback. I tried a bunch of ideas on the web but I can't seem to get any working.

  • Using multiple databases within one application

    - by Alex
    I have a web application made for several groups of people not connected with each other. Instead of using one database for all of them, I'm thinking about making separate databases. This will improve the speed of the queries and make me free from checking to what group the user belongs. But since I'm working with LINQ to SQL, my classes are explicitly connected with the databases, so I will have to make separate DataContexts for all of the databases. So how can I solve this problem? Or should I just not bother and use one database only?
