• Windows Forms OpenFileDialog throws ThreadStateException

  Hello. I have converted a C# project from VS 2003 to 2005 and am now continuing to work on it. It all seems to work fine, the some small issues could be solved very quickly. I have also converted the project files design manually to VS 2005's, with Form.Designer.cs files and a Program.cs containing the static Main() function. I've copied the code partially from other solutions newly created with VS 2005 so that it's complete. Now I wanted to use an OpenFileDialog in my application but as soon as it is to be displayed, it throws a ThreadStateException telling me I should add the STAThreadAttribute to my "main function". (Not the exact wording, that's in German. You can google that wording very easily.) But the initial Main functio ...Show All

• Visual C++ Building standard unmanaged win32 DLL which calls functions in a managed C# library

  Hi, I would like to build a standard DLL which calls managed code library. Is it possible If possible, how Can anyone provides some references to online resources With many thanks. Ok, yeah you are having a bit of a problem. The program.cs file is a C# file. When you add it to the C++ project, you are going to have huge problems because the C# code inside program.cs will be compiled with the C++ compiler. See where I'm going here So in order to get this to work, you need at least 3 projects. The C# project containing program.cs. It will output a DLL The C++ wrapper project. It will also output a DLL The native C++ project. (1) should just be compiled as you would any other C# project. (there is no /clr flag ...Show All

• SQL Server SQL server 2005 POOR performance on a good dev machine

  Hi there, I was wondering why my installation of SQL server 2005 on my Del inspiron notebook is so slow when using the Management Studio. I get the message that sql server is waiting for a process to finish quite often and it just seem to be bloody slow in general- like when i populate a table by hand I have a dual core intel 2.6gHZ Dell Inspiron with 1gigs of RAM and a 7200rpm drive. It should be more than sufficient. Regards Mike Well, client tools are really slow ones, in comparation with SQL 2000 tools at least, this is true. But engine works perfectly, and mostly faster than SQL Server 2000 engine does. ...Show All

• Visual Basic Newbie needs guidance on the next step past GUI--Importing Stock Data into App

  I'm taking a VB class for financial analysts, and we're tasked with constructing a progrm we can use on the job. What I'm trying to do is build a VB program that will take Stock and Company information from certain sites on the Internet and extracting that information into the program to do some research on a company before investing. I have some grand plans, but based upon what I have read/heard I'm starting by taking stock information from two websites (Yahoo Finance and Reuters) and populate several different tabs in this program I'm making (exporting to an Access database and Excel are also in the works, but I'm taking baby steps). I built the GUI with 4 different tabs that will house Earnings data, Trading Information, Company News, ...Show All

• Windows Forms Flattening entity collection for display in Grid

  hi, consider the following entities. public class Address { string street; } public class Customer { private int _name; Dictionary <string, Address> _addresses; public int Name { get { return _name; } set { _name = value; } } } As shown, Customer entity has a collection of Address entity.

• SQL Server Automatic sync between SQLce and Access

  Hi, I am converting an old eVB application to CF.NET 2. It's a very simple setup. 1) An Access database sits on the host and has occasional edits applied to it. 2) An application on the PDA with a mirror copy of the Access database (filtered data) and also has occasional edits applied 3) When the user puts the PDA in the cradle the databases get automatically synchronized with each other. Probably couldn't get much simpler than this. This used to be very easy to do with PocketAccess and ActiveSync. Unfortunately this is no longer supported. I decided to use the new SQLce database instead when porting to CF.NET. It's working like a charm except that I haven't found an easy way to synchronize with the desktop Access application.

  H i there,   I'm working on an engineering spreadsheet (Excel) and need some help in manipulating comboboxes / dropdown list.   Say i have 2 list, where list A has the list of countries and list B has the list of cities for the country chose.

• SQL Server SQL 2005 - Consuming web services in a Stored Proc

  Assume I've created a web service named 'SaveActivityData' for some SQL 2005 database on some remote server. Also assume that the stored proc takes two parameters; the first is an integer value and the second an XML value. 1) Is it possible for a stored procedure on a completely different SQL 2005 server to consume this web service 2) If the above is possible, could someone show me an example of the T-SQL syntax required to consume this web service, passing the two required parameters In your example, you can make up whatever URL you like for the remote web service location.
