• Visual Studio 2008 (Pre-release) How can i define a string tables in WPF project

  How can i define string tables as resources in WPF project  These string tables are used to localize the application. What can i do to add some CultureInfo into these string tables How to localize  the application with these string tables Thanks If I understand you right, you are building your app with UICulture set to en-US. Then generating zh-CN resource dll. Correct Can you confirm that you have en-US listed as the ultimate fallback locale Add (or uncomment if created within VS) this line to Properties\AssemblyInfo.cs: [assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.Satellite)] This way, when the app runs on any locale not ...Show All

• SQL Server (Select All) Checkbox As Default

  All, When creating a dynamic parameter list from a query, Reporting Services graciously provides a "(Select All)" checkbox. How can I select this checkbox by default so that when a user generates the report, all of the values are selected Thanks The "select all" item is just a UI concept at this point. You could setup a default value for the report parameter that contains all values of the valid values list - but in that case all the checkboxes for individual items would be pre-selected, but the "select all" would still not be pre-selected. -- Robert ...Show All

• .NET Development XslCompiledTransform.Transform very slow

  XslCompiledTransform is taking more time to transform xml file using xslt files. XslCompiledTransform.Load() , loads and compile xslt faster, but XslCompiledTransform.Transform() is taking more time to transform then using XslTransform class. I have C# code in xslt files for data manipulations and sometimes xml files may be big in size. The memory consumption the Transform method has depends on the size of the XML input and the size of the transformation result, it builds an XPathDocument in memory for the source tree and transforms that to a result tree that is being serialized. ...Show All

• SQL Server Flat File Connection manager throws error when a column gets added to the flat file

  Hi, I have a situation where a tab limited text file is used to populate a sql server table. The tab limited text file comes from a third party vendor. There are fixed number of columns we need to export to the sql server table. However the third party may add colums in the text file. Whenenver the text file has an added column (which we dont need to import) the build fails since the flat file connection manager does not create the metadata for it again. The problem goes away  where I press the button "Reset Columns" since it builds the metadata then. Since we need to build the tables everyday we cannot automate it using SSIS because the metadata does not change automatically. Is there a way out in SSIS ...Show All

• Visual Basic How does this work?

  Can someone explain how the IDE does this, so that I can make my own code to perform the same type of operation. If I create a connection to an access database, then I create a dataset for specific information, I can bind data to a combobox and it will fill the combobox with the information that I want. I can do this in code with a datagridview, but not with a list box, or combobox, or textbox (when i say I can't I mean I can't, not that it can't be done, just to clarify) Any help documents, forum topics, or other sources to learn how to do this is greatly appreciated. If someone needs to understand more about what I am trying to do exactly, please ask and I will explain it to the best of my ability. I don't want anyone to write the code f ...Show All

• Visual C# Using private constructors in embedded classes

  Hi. I have a pretty simple question, though I don't know if it has a simple answer: I would like to define a class-within-a-class such that the embedded class can only be created by the outer class, but once created can be accessed publicly (similar to a factory pattern): class A { public class B { private B() { ... } } public B CreateB() { return new B(); } } This doesn't work as written, I get A.B.B() is inaccessible due to its protection level, and I get "inconsistent accessibility" errors with any other configuration I try. Is there some other protection level that will allow B.B() to be accessible to A, but not to anything outside of A Also, I'm not super clear on this "inconsistent accessibility" co ...Show All

• Visual Studio 2008 (Pre-release) Possible Bug about Bubbled Events and Focusable

  Looks like I got to the root of the problem. In my hierarchy (I've made a post about it recently) there are 3 controls: Grid (Top), ScrollViewer (Middle) Grid (Bottom). I'm subscribed for MouseDown of the Bottom, but when I click on the Top nothing happens. After hours of investigations I found that the culprit is.Focusable property of the Middle man –ScrollViewer. Being set to True by default, it prevented my ScrollViewer from both Receiving & Routing of my Bubble MouseDown event. Once I set to False, it starts working. What is really interesting, that the actual value of Focusable property of any of my Grids doesn't make any effect. I do realize that ScrollViewer is a bit of a special control, in ...Show All

• Windows Forms How to create and Invisible Groupbox

  I am creating an application for a Tablet PC that has a flash movie playing in the background and looks for input from the user (from a writing area I have defined in a groupbox on the main form). I am curious how to make this groupbox invisible but still usable so that I can show it and unshow it without anyone knowing the difference and it will still collect the pen input. Thanks! I tried to create a form within a form using the MDI functions but the only thing I get it to do is Form2 replaces the contents of Form1 and then nothing else works. I am not quite sure how to code a new form (Form2) to appear at the bottom of the parent form (Form1) that is floating on top of the contents of the parent form. Have any suggestions or ...Show All
