• Visual Studio Express Editions Starter Kits are a nice idea - but in reality they are a huge waste of time

  I am the CTO of a large Microsoft-centric tech consulting service. I have spent considerable time over the past month studying and trying out this new starter kit technology. While I must say these starter kits are a great idea, the reality is that they are so poorly supported as to make them worse than useless - they are a waste of time and energy. My take is that they can't be easily installed correctly, as I have attempted installs of each starter kit on various systems, local and remote, and nothing runs. I have wasted hours on these forums, finding an incredible number of similar postings that mirror my own experiences, but none con ...Show All

• Windows Forms DataGridView - Binding to object & sorting

  Hi, I'm trying to bind my Windows Forms Data Grid View to a list of business objects. Trouble is when I do this none of the columns are sortable despite setting the sort mode to Automatic. I've tried a variety of things to get automatic sorting working with no luck. How is it done Cheers When the DataGridView is databound it asks the datasource if it supports sorting and only enables sorting on the columns if it does. When binding to business objects through a BindingSource the BindingSource does not implement sorting, so the DataGridView does not enable sorting. Check out this article for more information on adding sorti ...Show All

• Visual C++ Dynamically bind to a library and function

  Within my .NET managed class instance called LibraryFunction i want it to be able to: 1. Dynamically load a given library given it is not already loaded. 2. Dynamically bind to a function/method within this library. 3. Call this function with a given set of parameters. The binding is made possible by instance variables like mLibName and mFunctionName. My current unmanaged class uses code like the following: FARPROC f = (FARPROC)NULL; HINSTANCE libHandle = GetLibraryHandle(( const char *)mLibPath); if (libHandle == (HINSTANCE)HINSTANCE_ERROR) return NULL; else { f = loadLibraryFunction(libHandle, ( ...Show All

• Visual Basic Creating Relations within a Dataset

  im having a bit of trouble creating relations my dataset has 3 tables (client, episode, appointment) one client can have many episodes, and any 1 episode can have many appointments Client (0) INUMBER - primary key Episode (1) ENUMBER - primary key INUMBER - foreign key Appointment (2) ANUMBER - primary key ENUMBER - foreign key so i thought to set up my relations i would only have to do the following:- dsResults.Relations.Add( "NodeRelation1" , dsResults.Tables(0).Columns( "INUMBER" ), dsResults.Tables(1).Columns( "INUMBER" )) dsResults.Relations.Add( "NodeRelation2" , dsResults.Tables(1).Columns( "ENUMBER" ), dsResults.Tables ...Show All

• SQL Server List all your connection managers

  Hello, I'm building a custom task which has a property ConnectionManager which obviously allows you to select which connection manager you're goinng to use. I know how to get the list of connection managers but how do I make them appear in a combo-box in the properties pane Anyone got some code for that Hopefully this is fairly trivial for you developer types out there. Thanks Jamie I believe that the key is the TypeConverter property of property objects. If you were talking about a custom property in the Data Flow (which I realize is not your question) whose values came from an enumeration, using TypeConverter would both constrain the ...Show All

• Visual C# Getting StreamReader to recognize unicode escape characters

  I am reading in a file which has a header similar to a java properties file. name=My Software Package The issue is the value of the property (the right side of the =) can contain unicode escape characters (\udddd). When this file is read in by my StreamReader (new StreamReader(file, Encoding.UTF8)) the escape characters are not recognized as individual characters. Instead of seeing one symbol they are read in as six chars (ie \\u02ed ). Is there any way to read in this file so it will recognize these escape sequences I have tried all sorts of variations on use the Encoding.Decoder classes to no avail. As well as stripping out the \\ ...Show All
