• Windows Forms ComboBox DataBinding & CurrencyManager

  I am having trouble displaying the correct value in a combobox when the position of the CurrencyManager changes. I have a pretty complex DataSet with 5 DataTables and 4 DataRelations. For this particular, only 2 DataTables are involved with one DataRelation. The major DataTable is Products, all of the controls on the form bind to this DataTable or is Related to it somehow. One field of the Products is a CustomerId, which can be selected from a ComboBox. The DataSet has a related DataTable for Customers through a DataRelation CustomersProductsRelation (note: it seems that Customers is major to Products because of the one-many cus ...Show All

• Smart Device Development Trouble with DataGridTableStyle under 2.0

  Lets say I have a DataTable with 5 columns and I am only interested in displaying 3 of those 5 columns in my DataGrid.  I add a tablestyle to the datagrid and then add 5 column styles to it's GridColumnStyles collection.  I configure the desired style properties for each of the five columns being careful to assign a width of "0" to the columns which mapped to the column names which i wished to hide.  The problem is that these styles don't seem to effect the display of the datagrid at all.  All the columns were displayed.  I peeked in the *.Designer.cs file and I can see the code that was generated as a ...Show All

• .NET Development Starting one proccess from another while a third is locked up

  I am programming in VB.NET (2005) I do not seem to be able to start process B from process A whilst process C is locked up waiting - as it happens - for process A to tell it that process B has started. From some other behaviours I am guessing that the new process B can not start while another process (C in this case) has not returned from processing a windows message. I think there is some way for process C to process messages in the windows message loop via a function call (rather than returning) Does anyone know this call - or another way out of my dilemma which does not involve returning from processing its win ...Show All

• Visual Studio Express Editions Trouble finding/reading file

  Hello everyone I am having the hardest time right now.  I am testing backing all my DB tables to text files and then reading them in to populate the tables.  I am able to create the files without problem.  But when I go to read them in, I am getting the "Could not find file error".  Below is a small sample.  File exists is coming back false and trying to open the delimitede file is throwing the error (which makes sense because it is not being found).  I can see the file withing the directory I specify and when using normal windows search tool, the file is found.  What might I be doing wrong   Thank ...Show All

• Visual Studio Slow Wizard Input using MonitorArgument

  I have 6 arguments. The first is the only one shown in the wizard. The remaining 5 use MonitorArgument and the Evaluator (ExpressionEvaluatorValueProvider).

• .NET Development N-Tier Application - Question about Static Methods

  I'm starting an n-tier application with an ASP.NET 2.0 presentation layer, a business layer, a data access layer, and a SQL Server 2005 database, and I have a question. In the business and data access layers, should I use static methods   Or, should I code the classes so that they have to be instantiated   I've seen examples of both, and I'm not sure which is the "preferred" or "best" way. Thanks. Well. I guess that I agree in your comments. Howerver, there is also an other point of view. You may wan to use instance methods if you required that by one of the folloiwng reasons as well: 1. If ...Show All

• Visual C++ Ensuring symbol order in object files?

  Is there a way to get the C++ compiler to generate .obj files that maintain the order of the symbols as they appeared in the .cpp file   If so, is there also a way to ensure that the linker also preserves the order A simple example of the behavior I'm seeing from the compiler/linker: .cpp file contains int foo1; int foo2; int foo3; int foo4; when I dump the symbols from the .obj file I get this 00B 0000000C SECT3  notype       External     | foo3@@3HA (int foo3) 00C 00000008 SECT3  notype       External     | foo4@@3HA ...Show All

  Hi We wanted to branch our Team project. So we used Visual Studio to create a new empty team project.
