You can view all MIX videos (keynote and...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

    - by icelizard

  • Is it possible to tweak TStringField to work like TWideStringField in Delphi?

    - by mjustin
    We want to use Unicode with Delphi 2009 and Interbase, and found that to switch the character encoding from WIN1252 to UNICODE_FSS we first have to replace all instances of TStringField with TWideStringField in all datamodules. For around 60 datamodules, we can not simply do this over one weekend. I can see only two options for a migration strategy: find a workaround which allows to use the existing TStringField fields without triggering the 'expected: TWideStringField' error or remove all persistent fields to avoid the string type conflict As far as I know the field types for persistent database fields are registered in some kind of class registry. Could we use this to make Delphi believe that a TStringField is ok for a Interbase character column with UNICODE_FSS encoding? Or can we use a commercial dbExpress driver which work with TStringField in both cases?

  • Horizontal "tab"ish scroll between views

    - by Steve Pomeroy
    I'm interested in creating a horizontal scroll view that "snaps" to the viewed item, so only one item is ever shown at a time. The user can touch-drag left/right and will see previous/next views, switching to it if there's enough velocity. This interaction is exactly like what the new weather/news widget that comes with the Nexus One does for navigating between its "tabs". Are there any existing view widgets that do this? Update: found a copy of the news/weather widget (GenieWidget) and they seem to have implemented their own widget to accomplish this which they call com.google.android.apps.genie.geniewidget.ui.FlingableLinearLayout which is part of their own custom com.google.android.apps.genie.geniewidget.ui.TabView. As that source isn't available, that's not looking too hopeful a direction.

  • Facebook with RestFB (Java)

    - by Trick
    I just began to use this and I already stumbled on some from-my-side-strange errors. I am using RestFB jar. My problem is, that I can not get my session key (this is the start of everything :)). FacebookClient facebookClient = new DefaultFacebookClient(API_KEY, SECRET_KEY); try { String token = facebookClient.execute("auth.createToken", String.class, Parameter.with("null", "null")); System.out.println(token); String session = facebookClient.execute("auth.getSession", String.class, Parameter.with("auth_token", token)); System.out.println(session); } catch (FacebookException e) { e.printStackTrace(); } I get the token correctly. Parameter.with("null,"null") is there because it demands at least one, but method for creating token doesn't expect any. When trying to get the session key, I get the following error: com.restfb.FacebookResponseStatusException: Received Facebook error response (code 100): Invalid parameter at com.restfb.DefaultFacebookClient.throwFacebookResponseStatusExceptionIfNecessary(DefaultFacebookClient.java:357) at com.restfb.DefaultFacebookClient.makeRequest(DefaultFacebookClient.java:320) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:188) at com.restfb.DefaultFacebookClient.execute(DefaultFacebookClient.java:178) Documentation for getting session doesn't say any more parameters are required! Did anybody already try this JAR or do you have any other solution for Java? EDIT: Does the application needs to be "published" in searchers to be able to do this??

  • Explaining to boss why we need to avoid horizontal scroll

    - by Bradley Herman
    I need help explaining to my boss why her design is poor on a clients website. She has no knowledge of web and it can be difficult as a web developer working with a woman who is a graphic designer (not even a web designer really). On a current site she has designed, an image bar "needs" to be like 1200px according to her, though it isn't necessary with the content. I'll show a quick sketch to illustrate what's going on: http://imgur.com/MNGOT.jpg As you see, the banner spills out past the 960px of the content and as wide as 1200px. This creates a horizontal scroll when all the content is viewable within the 960px wide viewport. I need to make this an img and not a css background because it's a jquery slideshow that fades from image to image. I think this is a big problem because a lot of people are going to get a horizontal scroll bar imposed in their browser when they're still able to see all the relevant content. How do I help her explain it. She thinks no one will notice and it'll be fine, I think it's very bad practice and confusing to the end user. Any help?

  • Debugging web app on the palm pre?

    - by sold
    I have a web app that works fine on desktop browsers, but struggles on the palm pre browser (via the emulator). How do I debug the app on the palm pre browser? There doesn't seem to be any error console, dom inspector, etc... I'd expect such tools from a web-app oriented phone.

  • How can I process an image in .NET for a full-page print with a quality like Windows Photo Gallery d

    - by Triynko
    I'm writing a printing routing in C#, using the .NET PrintDocument class, handling the OnPrintPage event. I've managed to maximize the margins and print the Image in landscape mode, but it simply does not look as good as when I print the same image file from Windows Photo Gallery (formerly Windows Picture and Fax Viewer), the default image preview program in Windows Vista. I noticed an option there for selecting "Sharpen Image for Printing", but what does that do? I've thought about printing copies of the image from Windows Photo Gallery first, then sending the sheets through the printer a second time to print the custom overlays I need, but it's hard to make it line up every time, since the printer sucks the sheet in without the kind of precision I need... so I really need to do ALL the drawing commands within C#, including the image. Does anyone know how to perform pre-processing on the bitmap so that it prints as nicely as Windows Photo Gallery does it? Are there any simple print drivers that can intercept Photo Gallery printing output as a standard image file (bmp, png, etc.) that can be read by the .NET Image class? I'm all for creativity here.

  • Inner Join with more than a field

    - by Leandro
    Precise to do a select with inner join that has relationship in more than a field among the tables Exemple: DataSet dt = new Select().From(SubConta.Schema) .InnerJoin(PlanoContabilSubConta.EmpSubContaColumn, SubConta.CodEmpColumn) .InnerJoin(PlanoContabilSubConta.FilSubContaColumn, SubConta.CodFilColumn) .InnerJoin(PlanoContabilSubConta.SubContaColumn, SubConta.TradutorColumn) .Where(PlanoContabilSubConta.Columns.EmpContabil).IsEqualTo(cEmp) .And(PlanoContabilSubConta.Columns.FilContabil).IsEqualTo(cFil) .And(PlanoContabilSubConta.Columns.Conta).IsEqualTo(cTrad) .ExecuteDataSet(); But the generated sql is wrong: exec sp_executesql N'/* GetDataSet() */ SELECT [dbo].[SubContas].[CodEmp], [dbo].[SubContas].[CodFil], [dbo].[SubContas].[Tradutor], [dbo].[SubContas].[Descricao], [dbo].[SubContas].[Inativa], [dbo].[SubContas].[DataImplantacao] FROM [dbo].[SubContas] INNER JOIN [dbo].[PlanoContabilSubContas] ON [dbo].[SubContas].[CodEmp] = [dbo].[PlanoContabilSubContas].[EmpSubConta] INNER JOIN [dbo].[PlanoContabilSubContas] ON [dbo].[SubContas].[CodFil] = [dbo].[PlanoContabilSubContas].[FilSubConta] INNER JOIN [dbo].[PlanoContabilSubContas] ON [dbo].[SubContas].[Tradutor] = [dbo].[PlanoContabilSubContas].[SubConta] WHERE EmpContabil = @EmpContabil0 AND FilContabil = @FilContabil1 AND Conta = @Conta2 ',N'@EmpContabil0 varchar(1),@FilContabil1 varchar(1),@Conta2 varchar(1)',@EmpContabil0='1',@FilContabil1='1',@Conta2='1' What should be made to generate this sql? exec sp_executesql N'/* GetDataSet() */ SELECT [dbo].[SubContas].[CodEmp], [dbo].[SubContas].[CodFil], [dbo].[SubContas].[Tradutor], [dbo].[SubContas].[Descricao], [dbo].[SubContas].[Inativa], [dbo].[SubContas].[DataImplantacao] FROM [dbo].[SubContas] INNER JOIN [dbo].[PlanoContabilSubContas] ON [dbo].[SubContas].[CodEmp] = [dbo].[PlanoContabilSubContas].[EmpSubConta] AND [dbo].[SubContas].[CodFil] = [dbo].[PlanoContabilSubContas].[FilSubConta] AND [dbo].[SubContas].[Tradutor] = [dbo].[PlanoContabilSubContas].[SubConta] WHERE EmpContabil = @EmpContabil0 AND FilContabil = @FilContabil1 AND Conta = @Conta2 ',N'@EmpContabil0 varchar(1),@FilContabil1 varchar(1),@Conta2 varchar(1)',@EmpContabil0='1',@FilContabil1='1',@Conta2='1'

  • How do you encrypt parts of a file separately using pgp?

    - by Collin Anderson
    I would like to encrypt credit card numbers on a web server as they come in using PGP. I would then like to be able to export all of the credit card numbers and other information in one file that can be easily decrypted using standard PGP software. Is it possible to take the encrypted credit card numbers and join them with other encrypted data and be able to decrypt the entire file? Basically is this true? D(E(x) + E(y)) = x + y Where '+' means string concatenation.

  • Splitting tables by field to optimize MySQL?

    - by AK
    Do splitting fields into multiple tables ever yield faster queries? Consider the following two scenarios: Table1 ----------- int PersonID text Value1 float Value2 or Table1 ----------- int PersonID text Value1 Table2 ----------- int PersonID float Value2 If Value1 and Value2 are always being displayed together, I imagine Table1 is always faster because the second schema would require two SELECT statements. But are there any situations where you would choose the second? If the number of records were expected to be really large?
