• Visual Studio Tools for Office to retrieve event if mail item is moved VSTO oulook

  Hallo, i would like to know if it is posseble to to retrive a event if a mailitem is moved to a other folder. Gloat Helmut is correct (and a great Outlook dev resource!) The only thing I would add is that using this event is good; just keep in mind that it will also fire if an item is copied into the folder. You will have to add additional code to detect whether this is an item being moved or if it is being copied. John ...Show All

• Visual C++ When "It just works!" doesn't. :(

  Hi, To test out "C++ Interop", I created a static library in VC++ 6.0: Here is the contents of the header file (staticLibrary.h): #ifndef STATICLIBTEST_H #define STATICLIBTEST_H #include <string> using std::string; int add352(int value); string sayHello(string name); #endif Here is the implementation (staticLibrary.cpp): #include "staticLibrary.h" int add352(int value) { return value + 352; } string sayHello(string name) { string s1("Hello, you are the greatest, "); return (s1 + name + "!\n"); } This code compiles fine in VC++ 6.0 and it produces an object called "staticLibrary.lib ...Show All

• Visual C++ random numbers

  I have recently been trying to get the random number generator that comes in the default libraries to work.. I can't get the rand() to acctaully create a real random number to my wanted parameters. For example if I say wanted a number between 1 and 10 I would try: int random_value random_value = (rand()*10)+1 I would then be able to use that random number for switch processes etc. The problem is that the number is not random, the random number is always the same, with any one particular seed. Please is there another easier way of creating random numbers that are really random. I believe that it is possible to use the date as a seed which is always different, but I want a random number between 1 and 0 so t ...Show All

• .NET Development .NET program in autostart

  I've created a very simple "hello world" program with C# 2.0 (VS2005) and placed this program into the autostart folder. On startup the console window shows up, but it remains empty for several seconds. Only after about 5 seconds the "hello world" message appears in the console. I tested the program on a different computer (the hardware is pretty much the same) and the delay is much shorter (about 1 sec). I guess that it has to do something with the initial setup of the CLR. How can I speed this up Check the System and Application Event logs to see if anything gets reported at system startup. ...Show All

• .NET Development Delegate on my custom class members

  hi, I want that when the values of my class members change, a method will be called. For Example C#: Why not use delegates (I.e. why invent something to work like a delegate ) That's what they were put in the language for! Forgive me if you already know how to use delegates; in case you don't, here's how I might do what you want using delegates: using System; namespace MyStuff.NotifierClasses { // The delegate declares the signature of the method to be called by the event. public delegate void ValueChangedDelegate( object o, ValueChangedEventArgs e); // This method records the name of the property that triggered the change event, // and the new va ...Show All
