• Windows Forms DataGridView: why not remove new row when saving?

  I have a DataGridView bound to a BindingSource which in turn is bound to a collection of objects. In the BindingSource's AddingNew event, I will create a blank object, like this:     private void myBindingSource_AddingNew(object sender,         AddingNewEventArgs e)     {         MyClass obj = new MyClass();         e.NewObject = obj;     } The problem is after I finish editing the current row, and press Tab key, it will go to the next row and a blank object will be inserted in the collection. Then when I press save button, the blank object is invalid and validation will fail. Or I have to point to a ...Show All

• Visual Studio Express Editions Guessing somthing has changed. Array Issue

  here is my code, a simple declaration of a array in VC++ exp. I'm watching the 3dbuzz video tutorials on C++ to try and pick it up, yet though their version of Visual C++ allows it, mine gives me this error: error C2440: 'initializing' : cannot convert from 'int' to 'int [3]' Code: #include <iostream> void main() { int myarray[3] = (0); } I just want to create an array and assign all values of said array to 0. What am I doing wrong here Thank you for your time. Not quite, do this: int myarray[3] = {}; All 3 forms are possible and the result is the same, an array with all elements initialized to 0. int myarray[3] = {0, 0, 0}; // this is obviously correct int myarray[3] = {0}; // t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 2 Questions for Beta 2: Flipping and Initializing

  Hello! So, yesterday I've finally compiled my game under new Beta :) And an hour ago I've even launched it. Now I got 2 questions: 1. Help says: "The Initialize method is where you can initialize any assets that do not require a GraphicsDevice to be initialized." Well, when I work with my program GraphicsDevice seems to be well initialized in Initialize (more exactly after calling of base method). Is it just a side effect and I should not rely on it or it is an error in documentation 2. I use SpriteEffects to flip my batches. When I first run my game under Beta 2 all sprites are not flipped. I've look through documentation but got no clue - XNA seems to be ignoring SpriteEffects. What's wrong Thanks! Stas ...Show All

• Visual C# local or remote path

  Hi, how can I determine (inC#) if a path refers to a folder/file on the local machine or on another machine in the network Thanks for your help, Ralph Hi, Yes, its possible. I havnt gave you that info because its a bit lengthy process. So i thought if not required then why one would like to go for unneccessary long process. Any way, for your solution, please use the following code. I have made a sample for you but as per your requirement, you change the methods, return types and the information how its being filled in these methods. For this, you will need to use Management apis (WMI) to get the mapped drives. So add System.Management.dll as reference in your project using "A ...Show All

• Visual Studio 2008 (Pre-release) Setting the focus to an editable combo-box with code

  Hello everybody, In a WPF application, I have a dialog-box Window on which there is an editable ComboBox inside a TabItem (first displayed tab). I'm trying to set the focus on this control when the window is first displayed. To do this, I called the Focus method on the combo-box edit, on the window constructor, just after the call to the InitializeComponent method call. The focus is changed by the call but is not really on the combo-box edit: - The combo-box is displayed with a blue border that indicates the focus. - The caret is not displayed in the edit part of the combo-box. - If I press the Alt key 2 times (one for the menu and one to exit the menu), a dashed box is displayed in the edit part of the combo-box. - If I press the Tab ...Show All

• Visual FoxPro Help: Open a Table from within a Report?

  Hi, I am supporting an Accounts program that is written in Visual Foxpro. I am editing a Report using the Report Designer and the Data I wish to access is in a Table that is not open in the Data Environment, and I cannot simply Open it and Save as the Data Environment reverts when re-opened. I am aware that there is a way to Open a Table in the Header of the Report by adding a Field and using a Command in the Expression Builder as I found out about a year ago, unfortunately I cannot remember or find the Command for doing this. Can anyone put me out of my misery and give me some help on how to acheive this Many Thanks. Then you may use a expression with field: expression(<table name> ...Show All
