• Visual C++ Delete a certain tree node

  hi, now i facing a problem which i do not know how to solve it...:( My binary search tree structures stores a double number in every node, whereby a higher number is appended as right child and a less or equal number is appended as a left child. Now i want to write a function which deletes the node with the highest number in the tree. I started the function as follows: [code] template <class Item> void bst_remove_max(binary_tree_node<Item>*& root_ptr, Item& removed) // Precondition: root_ptr is a root pointer of a non-empty binary // search tree. // Postcondition: The largest item in the binary search tree has been // removed, and root_ptr now points to the root of the new (smaller) // binary search tree.

• Windows Forms how to use datagridview to extract values from a function?Urgent matter

  Can anyone show me step by step how to make use of Visual Studio2005 C# toolbox function: DataGridView to retrieve values from a function Example: Give a function give values X,Y,SeqNum and Curvature when i select some feature points on a picture.And i want DataGridView to show me a table of the values. Is it possible to use DataGridView to show or is there any other way It depends on how your function returns the values you want to display, but mostly, you can use the Rows.Add() method to add values to the grid. Lets say your grid is named grd and that you want to display 4 values as you mentioned earlier. First, you add a DataGridView to your form and give it a name, say grd Then you use VS 20 ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Problem with ALL!!!! Downloads of Direct X SDK

  It is really frustrating. I need the Direct X SDK but unfortunately all the sdk i downloaded are saying "filepath is wrong" when i click on download dialog "open" or i would like to unzip it i get pretty much same kind of error- or with the newest one (aug 2006) it told me it is not a WIN32 Application even that it said it is for Windows 2000 what i am running on my machine by the way. I also downloaded the Microsoft platform SDK no problem but i really NEED the DirectX one too because my application gets the strmbasd.lib not found so i need the baseclasses! Thank you! I'm not sure why you are getting the download problems. Downloads seem to work fine via the internet. However, you ...Show All

• Smart Device Development Pocket PC Windows App

  Hello, I have a question related to the execution of CF .NET Win App code. private void Form1_Load(object sender, System.EventArgs e) { label1.Text = "Waiting for connection..."; Connect(); // uninportant implementation label1.Text = "Done."; } Connect() function is running in circle, until it doesn't get a connection.

• Software Development for Windows Vista Visual Studio 6.0; VB6 GetAllSettings function does not seem to work in Vista RC-1

  Visual Studio 6 seems to come up correctly however when testing stable VB6 application the following line: varFiles = GetAllSettings(ThisApp, FileKey) produces "Run-time error '5'; Invalid procedure call or argument. Both procedure call and arguments from this working program are valid. This project is completely stable on WinXP machines and below. I have not seen this error until upgrading to Vista.

• Visual C++ Two Projects Colliding

  I have a project with twenty configurations (I'll call it "project A"). I suddenly had a need to build two versions of all those configurations - one with dynamically linked CRTs, and the other with static linked CRTs. So I decided to duplicate the project file, giving it a new name ("project B"), and added it to the same solution. I changed the name of its executable output, so it would not overwrite the other executable being produced. This trick only works by declaring project B to have a dependency on project A, and using the "rebuild" command. If I just use the plain "build" command, I get all kinds of linker errors of identifiers already found. This is because both projects are sharing th ...Show All

• Visual Basic Single.Parse(999999999) = 1.0E+8 (100000000.00) ???

  Hi....... Quote: Single.MaxValue = 340282300000000000000000000000000000000.00 When trying to parse a value like 99999999 to single, it gives me 1.0E+8 (100000000.00). This is not i was expecting and ofcourse no one would.....How to resolve this type of problem. I cannot (now) go for double coz its already late. I even tried Convert.ToSingle and Ctype way but all yielded the same result . Please help me out of this... Unfortunately there is no good way out of this. While Single's have a big range of numbers they can represent, they cannot represent every number in that range. In many ways Single's are an approximation of a number. If you want 100% accuracy you're going to have to use the Decimal type. ...Show All

• SQL Server Improving Chatty applications

  All: I am presently tasked with improving the performance of a chatty application. What I mean by a chatty application is that the application makes multiple calls to the database server for each user request. In many cases it appears that many of the windows are making multiple calls to the database for the population of dialog boxes. In a couple of cases there are more than 10 dialog boxes that are populated similar to this. To me this is kind of an "old issue", but my response is (1) cache the dialog information as much as possible and (2) make one call to the database to return all of this data for the dialog boxes if it is not cached. For update calls again make a single call to the database rather than making a call f ...Show All

  Hi, can someone help me understand a bit better how to detect a checkin conflict programatically I mean, if I want to do a non-exclusive check out, modify a code and then try to do a check in automatically, how can I verify that a conflict is occurring The Checkin method call will throw a CheckinException instead of returning back a changeset.   The message (if english) will be something like TF10141: No files checked in: resolve the conflicts and try again, and you can check the Conflicts property on the CheckinException itself to access the conflicts if there were any. ...Show All

• Visual C++ C++/CLI: why does a reference variable on the stack need a copy constructor?

  Dear all: A very stress problem I met these days. How can I read and edit a file in a storage when doing HD-DVD actions For example, how to edit a file under path "file:///dvddisc/ADV_OBJ/questions.txt" or file:///filecache/questions.txt ".
