How to code that one, it seems my code below is not working. result is always 0; System::DateTime moment = System::DateTime(11); int millisecond = moment.Millisecond; ****************************** I just want to know everything Re: How to get the seconds/milliseconds in DateTime? Luc Pattyn2-Jul-07 5:28 Luc Pattyn 2-Jul-07 5:28  AFAIK the constructor accepts a number of ticks (1/10 of a microsecond), so your moment is almost zero.

And how do you "know" that? You haven't been reading the documentation have you? Can't you get in trouble for that? Re: How to get the seconds/milliseconds in DateTime? Luc Pattyn2-Jul-07 6:05 Luc Pattyn 2-Jul-07 6:05  I plead guilty; I am known to occasionally read the documentation. Sometimes I even believe that helps me in understanding what is going on and why. Luc Pattyn [My Articles] [Forum Guidelines] Re: How to get the seconds/milliseconds in DateTime? C#Coudou2-Jul-07 19:50 C#Coudou 2-Jul-07 19:50  Thanks to all. I got it. :-> ****************************** I just want to know everything network speed detection C#Coudou1-Jul-07 15:40 C#Coudou 1-Jul-07 15:40  Bros, How to code the network speed detection? What i mean is i want to detect the upload and download using clickbutton. When I press a button it will show to textbox1 the upload speed and textbox2 the download speed. example: TextBox1 = 42 kbps TextBox = 54 kbps Is anybody here how to do that? Much better if you can give me some links for basic. Thanks in advance. ****************************** I just want to know everything Re: network speed detection Perspx2-Jul-07 11:24 Perspx 2-Jul-07 11:24  I doubt there is a way to simply find this as there isn't really a fixed upload and download speed, as the server at the other end is a factor of the upload and download speed.. You could get the application to, for example, download a file and work out the speed in kbps from that, and do the same but upload a file..? This would give an estimation to the upload and download speed.. Hope this helps! --PerspX how to retrieve sub directorires under a specified directory cy163@hotmail.com29-Jun-07 23:24 cy163@hotmail.com 29-Jun-07 23:24  Hello, I need to retrieve ALL subdirectories under a specified directroy in my C++ program. Could anyone please tell me how to do this. Thanks cy163 Re: how to retrieve sub directorires under a specified directory Luc Pattyn29-Jun-07 23:40 Luc Pattyn 29-Jun-07 23:40  You can with one of the overloads of Directory::GetDirectories specify AllDirectories if you want it to work recursively, (or organize a recursion yourself if you are still on .NET 1.x) Luc Pattyn [My Articles] [Forum Guidelines] String Format how it works. earlgraham29-Jun-07 6:04 earlgraham 29-Jun-07 6:04  When I have the following code String ^sBuffer;<br /> sBuffer->Format("Target number is {0}", this->id); sBuffer will not be updated, but if I change it to String ^sBuffer;<br /> sBuffer= String::Format("Target number is {0}", this->id); It seems to work well.

Re: To add a class to the project Sivakumar R29-Jun-07 5:08 Sivakumar R 29-Jun-07 5:08  1. You can just copy the .h/.cpp files in to the project folder. 2. Right click on the Project in the Solution Explorer and selecct Add->Existing Items 3. Select all the .h / .cpp files from the open file dialog 4. It will add your existing classes into the project If you want to add the files from the different folder than your project folder, make sure you set the include path correctly. Regards, Sivakumar R Re: To add a class to the project mikobi2-Jul-07 2:38 mikobi 2-Jul-07 2:38  In Solution explorer I don't see the files that a copy in the folder, but with explorer I see them. What to do, I think this class was not build with Visual c++ NET 2005. Is it the reaon ?

It isn't really much different than doing the same in C# or VB.NET... You just have to deal with the language syntax.
