• Visual Studio Express Editions Finding the cubic root

  I couldn't find any function for the cubic root in the System.Math class, only the Math.Sqrt() function, I decided to write my own function. After some searching I found out about the formula for Newton approximation method and implemented it in my own function. As you might understand, you can only approximate it. If you are in need of computing the cubic root, please feel free to copy and paste the code, or change it if you want. I see no reason to protect this code that isn't even optimized yet. If you anyone has any suggestions how to improve it, please post it here. /// <summary> /// Computes an approximate cube root of a ...Show All

• .NET Development txt File partition

  Hi, I need to read a .txt file , partition it into smaller .txt files ,and then saving them. The partition process depends on finding the carriage return (enter) character. How can I doing that Thanks in advance , Aya. You might want to be careful doing the way that Kevin suggested as this will cause problems when reading large text files. His solution will read the entire text file into memory and then make another copy of it. So if the text file you reading is 10 MB, you application will consume 20 MB memory when calling this method. It might be better to read a line in at a time: ...Show All

• Visual C++ error LNK2005: "void __cdecl bp5(void)" (?bp5@@YAXXZ) already defined in test.obj

  Hi All, I generated a simple SDI skeleton using the wizard, and tried to #include some of my libraries. It gave me a bunch of 'LNK2005: ... already defined ' errors. I repeated the basic SDI generation in another project and this time only tried to include a single, trivial header file: mytest.h #pragma once //#include "stdafx.h" void bp5(){  int a = 0;  a+=1; } I include this file in the testDoc.h file of my test project. Despite that this simple header file is so basic, and despite the #pragma once directive, it still gives me the same LNK2005 error! Can somebody kick me and tell me what's wrong Thanks ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Creating a very simple GUI

  I am trying to integrate a very simple GUI into the project I am working on. All I need is 3 edit boxes to accept values and a button to execute a command. That's it. I have looked at the tutorials included with DirectX, and the GUI example is simply too complicated...I don't want to include a bunch of files I probably won't even need. What's the easiest way to implement a GUI like the one I am describing (By the way , I am writing this in C++.) thanks in advance. >What is wrong with the sample code provided in the SDK (Custom UI) It can't be used unless you use the whole of the framework.

I've successfully created a web service on the BW side, but could not find any information on how to consume the web service in .NET, since most people seem to prefer the .NET connector or direct ODBC connection. Any references/documents are much appreciated. By the way - I know how to create a web reference, proxy class, etc. It's just that I don't really know how to use the WS istself. ...Show All

• Visual Studio Express Editions Updating a database using a TableAdapter where a column was added programatically

  First time a data application, I need to change number of columns in runtime programatically and save it back to the database. I managed to read data from a manually filled database using a TableAdapter as shown in the examples. I used the dataset design tool to create the TableAdapter methods (GetData() generated by the wizard) and filled a DataTable object. Data got there correctly. However I tried to add a column to the DataTable object and save it back to the database. The TableAdapter.Update(DataTable) did nothing. After many hours I figured that maybe the automatically generated Update method created visually in the desi ...Show All
