Visual Studio Indentation in code-tag in included xml-tag
If I want to use a <code>-tag containing indentation in an Xml documented member, I can do it like this: /// <remarks: /// <code> /// <MyKey > /// <registrations default="<i>MyDefaultRegistration</i>" > /// < /MyKey> /// </remarks> This works fine. However, I have some sample code that I need to use a couple of times so I wanted to copy this sample code to a separate Xml-document and then reference this sample code using the <include>-tag. Like this: /// <include file='ApplicationDoc.xml' path='docs/member[@name="ApplicationLogon"]/*'/> The contents of my xml-document looks like this: < ...Show All
.NET Development Delayed Datareader column error
In a live application which i created, i noticed that after a day or two, i get a datareader error, specifically the error which returns a column name as it's message. i.e if i had written reader["col_name"] i get col_name as the error message. The problem is that i read 5 column names in a single read, and the messages vary, it not always the same column name. However, whenever i restart the server, the problem goes away for another day or two. Recently i increased my max pool size because i was having pooling issues, this had an effect on the datareader error in that it now occurs every 2-3 hours instead of the 1-2 days. pls i need help on this one Thanks I don't see anything wrong w ...Show All
Visual Studio Express Editions Norton like Taskbar icon
Hi. I was wondering if it is possible to make an icon like Norton has on the taskbar (Not the tray icon), the yellow one on it's left. It is directly a button on the task bar.

Visual C# generics: T Create<T>() where T : MyClass, new(...)
Is there a way to enforce a non default constructor And if not, why not ! I wrote a class that implements a constructor that is in need of an XmlDocument as a parameter. Several other classes inherit from this base class. Now I would like to write a generic create method that instantiates one of the child classes and sets some base properties: class MyClass { public MyClass(XmlDocument xmlDoc) { ... } public ElementName { get { .. } set{ ... } } } class ChildClass1 : MyClass { ... } class ChildClass2 : MyClass { ... } class MyClassFactory { ... public T Create<T>(XmlDocument xmlDoc) where T : MyClass, new() { T myClass = new T(xmlDoc); ... } ... } Obviously that does not work because the generic all ...Show All
Visual C# Update DataGridView?
I have following code for the form closing event: private void CurrenciesList_FormClosing( object sender, FormClosingEventArgs e) { dataGridView1.EndEdit(); if (dsCurrencies1.HasChanges()) { DsCurrencies chngs = ( DsCurrencies )dsCurrencies1.GetChanges(); sqlDataAdapter1.Update(chngs); } } Now, problem is the current cell: when I close the form changes on the current cell are not updated if I do not leave the current row. If I close form while I am still in the row all changes to this row are not accepted. It is like this that method EndEdit does not saves the curent row. How can I save current row in the DataGridView I believe if ...Show All

Windows Forms Leave Event
I have a set of codes which on load the first time ...i set a control's to focus and this trigger the lost focus event of the control.

Game Technologies: DirectX, XNA, XACT, etc. How can I start the XBox360 development progress?
Hi, In the company, I'm working for a great xb360 game now. Also I want to develop my own smart games for xb360. There are so many xb360 kits and other xb360-related hardware resources in my company but I can't use them for my business. So the question is: How can I get/buy the XBox 360 kit machine I can't see them opening up native development and C++ on the 360 without the $$ becuase of the way the console games are handled financially. The Console manufacturer has to control that process. Also there is a lot more security risk allowing this. We may see C++/CLR happen in Game Studio express at some point but it will all be managed code to allow security control. You can request this on the connect website for XNA http://forum ...Show All
Visual C# OleDb Provider, SQL Server 2005 problem
Here is my problem: I have a windows application that should work equally with SQL Server 2005 and SQL Express. This application uses Crystal Reports as report engine. When i use sql server, then for report i create diferent type of connection using OleDb, because crystal reports doesn't work with Sql Provider. And this works ok. But when i use SQL Express, then i can't open another connection because express alow only one connection. So i decide to always use OleDb connection for Sql Express. But my problem is executing command with parameters. When i have command like Select * from Users Where Username = @username and then add paremeter in that command with name @username , then it raise error with message Must declare the scalar variabl ...Show All

Visual Studio Express Editions View many database tables in one form
Hi. My program has a menu where you can choose between 90 database tables to view. My plan is to open another form with a parameter that says which table to show. So I have a form named Table. But the Table form needs to be able to choose between the 90 different tables. I drag and drop a table from the DatabaseDataSet, and thats one. But then I need to drag over another, and I got the problem. I need to be able to hide/'not create' all the other tables' datagridviews that I don't want to show. And without wasting resources on getting data from the other tables. Another problem is that the BindingNavigator (which I have modified) needs to operate with the chosen table. It has got a button which is going to export the table to Excel, and I' ...Show All
