• Visual C# why we did not declare Int32 in C#???

  As we know c# datatypes are object by inheriting the CTS classes. When we declare int anyVariable=anyValue; Exactly what we are doing . If we are creating an instance object of type int or what Please give me some detail idea.... Thanks in advance... Ashok An Int32 inherits from System.ValueType which in turn inherits from System.Object. Anything that inherits from ValueType (ie Int32, DateTime and any other structure) are actually created on the stack, whereas reference types, such as those that inherit directly from System.Object are created on the managed heap. Because of that, Value Types are typical ...Show All

• Windows Forms SizeGripStyle.Auto behaviour

     Can someone explain the behaviour of SizeGripStyle.Auto which is a value for the Form.SizeGripStyle property [Note: SizeGrip is the triangular section shown in lower right hand corner of forms to indicate it can be resized] According to the MSDN doc it just says "The sizing grip is automatically displayed when needed." What are those "When needed " situations. In the doc for Form.SizeGripStyle it says "You can set this property to display the sizing grip or have it automatically displayed based on the setting of the FormBorderStyle property" But setting the FormBorderStyle property to either Sizable or SizableToolWindow does ...Show All

• Visual Studio Visual Studio Debugger Crashes after Exception Thrown

  While in debug mode in a particular ASP project, Visual Studio will hang after any exception is thrown. This happens if the error is handled or not handled. The above stated problem won’t occur on a new ASP project. The problem project has approx 40 aspx files. Business classes are maintained in a separate class project. To shut down VS I need to “End Process” from Task Manager. Note: VS is usually using 85%+ CPU at that point. The project will even hang when I throw an error. t hrow new Exception(“dang”); The Exception window pops up with the correct error but I can't close it ...Show All

• SQL Server Left Outer Join

  Hi All Dudes and Dudesses Please help... I've got Two tables, Problem and Breach, in DB Support. The main Table (Problem) has a primary key on field Number and I retrieve most of my data from this table but the other fields are irellevant. The Breach Table includes fields: Number & Keyword. I use an Left Outer Join to connect from Problem.Number to Breach.Number and retrieve the Breach.Keyword if any.

• SQL Server Flat Files Containing Dates

  Hi everyone. I'm trying to use a Flat File Connector to read in a fixed field width file that contains some date columns. The problem is that the date column is in a CCYYMMDD format (with no delimiters) so that todays date, as an example, would be 20050711. When it attempts to import the file it fails due to a "Data Conversion Failed" error. I can't find any way to specify the format of the column in the FFC dialog so my only option appears to be read in the column as a string and transform it later. Is that correct Steve What do you mean when you say it "throws a cast exception" Have you tried en ...Show All

• Visual Studio Help still broken

  Just installed the release version of VS2005 standard. Alas, F1 help is still broken. If I position the cursor over a word (for example HANDLE) and hit F1, the following happens: 1. If MSDN is set to use local help only, it always displays the topic-not-found page, even though on the left hand side, the topic is not only present, but selected. A single click on the highlighted item displays the correct information. 2. If MSDN is set to use online help first, then pressing F1 takes up to a minute (looks like multiple redirections happening), then either displays the topic-not-found page or displays something only vaguely related to the select ...Show All
