How to Localize Windows Forms and Change the Language at Runtime

  
Localization is the process of customizing your application to a particular language, culture or locale. Visual Studio provides support for localizing Windows Forms with much ease. In this article, we will see how to localize windows forms and give the user the ability to change to his preferred language at runtime.
When you run a localized application, the appearance is determined by two culture values. The UICulture property is used to specify which resource files will be loaded for the form. The Culture property, on the other hand, determines how strings such as dates, numerals, and currency amounts are formatted.
Let us see the steps required to create a localized form. You can then expand this example and adopt the same approach for the rest of the forms in your project

Selected to change the background color of the page

  

Hi,

As this site, http://www.borfin.com.tr/genel/Default.aspx, How can I change the background color selected pages.


Bug: Does not change column type from nvarchar to ntext

  

Scenario: If you create a table with a column of type nvarchar, populate it with some content and try to modify it using the WebMatrix editor, from nvarchar to ntext, it does not display any error message or warning that this is not possible. It silently saves and reverts the change, back to nvarchar. Wasted some hours on this issue as I thought my column was ntext, but in fact was still nvarchar.

Expected behavior: It should change to ntext, or if SQL CE doesn't support that, it should notify the user that no change was applied.


How to change the default page base class?

  

I've tried setting the <pages pageBaseType="DynamicWebPage" /> value in web.config, but when I response.write out the page type, I'm still getting Microsoft.WebPages.WebPage.

I'm simply trying to sub-class WebPage and add some additional functionality such as a dynamic PageData dictionary similar to Phil Haack's dynamic ViewData dictionary.

Thanks,

SqlDataSource how to change the stored procedures at run time

  

Hi

Is it possible to change the select, insert and update stored procedure of an SqlDataSource at run time. I don't mean to change the definition of the stored procedure, but I mean to change the assignment, i.e. To change the select stored procedure from "selectSP1" to "selectSP2" at run time. Is it possible?

Easy image processing(grayscale, sepia, negative, resize, brightness, contrast and opacity)

  
Howdie y'all,

I see a lot of questions in this forum about resizing images. Recently I created a code sample(with downloadable webapp), right here.

The class (downloaded or created) allows for very fast and easy processing of your images. And a lot of problems over here can be solved by simply using that class. I thought it might help to mention the code sample in this forum as well.

Cheers,

Wes

dynamically change column names in Crystal reports

  

I need to develop 3 pages.

On the first page user defines atmost 7 column names to be displayed on the report. I'm saving these names in a Sql DB table 'Columns' with Column_Nm and Column_ID as Table columns.

On the second page I'm retrieving column_Nm from the table and displaying them on the page so that the user enters the data. This data is saved in another table 'Summary' with the Columns column1 through column7.

on the 3rd page I need to show a report of 'Summary' table.

How do I dynamically replace column1 through column7 names with that of 'Column_Nm' on the report?

Any help/suggestions would be appreciated.
