Hi all,
I need to move a sprite exactly 100 pixels every second regardless of the framerate. Any help would be great ..thx.

The simple answer is to obtain the current framerate and move the sprite by 100/framerate but what happens if the framerate falls below 1 FPS?

You could just use a heartbeat timer.
|

All games work this way, they move the sprites based on time passed, and render as many frames as the processor lets them. So, the key answer is, don't write any code that changes any values just because a render event has occured.

So .. am i right in thinking if i fix the framerate to 60fps and then every loop move the sprite 100 / amount of ms passed then if any time is left draw the frame?

you need an accurate timer (there is one in DXUtils class in DirectX SDK) and define your move formula depend on time and speed just like X=Vt+X0 for example if X0=0 and V=100px/sec then in 2Sec it would be 200px or in 0.01 sec it would be just 1px so it does not depend on the framerate
you can take two approach depends on your need
1- X0 would be always zero so after 10 sec you pass the 10sec to formula
2-use time Elapsed method (use in most games) you can calculate the elapsed time using the timer
and the previuos position would be X0.
for example if X0=0 and V=100px/Sec after one sec X=100px and after 1.5 sec from beginning it would be X0=100px ,V=100px/sec,ElapsedTime=0.5 sec X=100*0.5+100=150px
and if you are doing it in the 3D you must define each speed for every dimension or calculate them thruogh total speed using math
and ofcourse you involve acceleration too.
hope the post would be useful

please help me I want to know how to save the data of my streamwriter to the file I am saving in a directory from the savefiledialog.
I get the file to save with the right ext but the data does not.
|
|
|
|
|
I think the SaveFileDialog is just used to visually select the location and the name of the file to be saved. After that you write the contents of the file on the disk "by hand" using the class "StreamWriter" or "File" or whatever.
|
|
|
|
|
yes I know but how can I parse the values in my streamwriter to that file that Im saving from the savedialog?
|
|
|
|
|
Have you checked out Intellisense? SaveFileDialog exposes a property called FileName. Alternatively, you can call the OpenFile method on the SaveFileDialog instance.

Is Binary Serialization what you need?

Hello,
Do you mean getting the filenames from this path?
If Yes:
string[] allDlls=null;
string searchPath = @"d:\visual\source";
if(System.IO.Directory.Exists(searchPath))
{
allDlls = System.IO.Directory.GetFiles(searchPath,"*.dll");
}
All the best,
Martin

Hi,
have a look at the Process class, its GetCurrentProcess method and Modules property.

Dear all,
I got this project that was written originally on .NET framework 1.1. I converted the project with Visual C# 2005 Express , and it compiles just fine. However, when I want to run it I get a .NET framework initialization error , telling me that I need 1.1 in order to run the application. I though 1.1 was , without any restrictions, backwards compatible. How can I fix this without re-writing the entire code.
cheers,
|

You rebuilt the app using VS 2005 and *that* binary asks for v1.1? 
Have you tried running it through the debugger yet?
Cheers,
Vıkram.

Yup .. that's exactly what it does 
Weird huh ?
The debugger tells me that it cannot open a CLR and that I have to repair my Framework 2.0. However, other programs debug, compile and run just fine, so I highly doubt if it's the framework that is broken.

I need to get files from my c drive one-by-one using file uploader and put themin a list box then save the files to a server.
can someone help please.
|
|
|
|
|
And where exactly are you stuck? 
You can get files from a directory using the DirectoryInfo and FileInfo classes. Use the properties exposed by these classes to add them to your listbox. As for saving them to a server, it depends on what protocol you will be using.
Cheers,
Vıkram.
