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

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.

Have you checked out Intellisense? SaveFileDialog exposes a property called FileName. Alternatively, you can call the OpenFile method on the SaveFileDialog instance.

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.

framework 1.1 - 2.0 compatibility issue

28-Aug-07 21:46

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? WTF | :WTF:

Have you tried running it through the debugger yet?

Yup .. that's exactly what it does Big Grin | :-D

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.

And where exactly are you stuck? Suspicious | :suss:

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.

These are serverside. I think he is expecting something on the web browser. He might most probably need an ActiveX solution to achieve the same.

data type mismatch error

28-Aug-07 21:23

Hi everyone,

I've recentley started using C# and am doing an application to insert data using oledataadapter and dataset, and i have an error data type mismatch in this line 'int t1 = adapter.InsertCommand.ExecuteNonQuery();' can anyone tell mi what that means and what ive done wrong, because all my data types are text. Here's the code below:

   string strConnection = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=datacapt.mdb";<br />
            OleDbConnection conn = new OleDbConnection(strConnection);<br />
            conn.Open();<br />
            string strCommand = "INSERT INTO compdata(ID,CompanyName,ContactName) Values ('" + txID.Text + "','" + txtName.Text + "','" + txtcontact.Text + "')";<br />
            <br />
            OleDbDataAdapter adapter = new OleDbDataAdapter();<br />
            adapter.InsertCommand = new OleDbCommand(strCommand, conn);<br />
                             <br />
<br />
            int t1 = adapter.InsertCommand.ExecuteNonQuery();           <br />
             conn.Close();<br />
<br />
             if (t1 > 0)<br />
            {<br />
                MessageBox.Show("added successfully!");<br />
<br />
            }

Thanks very much
Csanda

Hi csanda,

You're trying to assign an insert statement as the value for integer t1, while an insert statement should be executed by itself and an integer can only have numbers as a value. I would do it differently. Try the following code :

void Whatever()<br />
{<br />
try<br />
{<br />
string strConnection = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=datacapt.mdb";<br />
OleDbConnection conn = new OleDbConnection(strConnection);<br />
conn.Open();<br />
string strCommand = "INSERT INTO compdata(ID,CompanyName,ContactName) Values ('" + txID.Text + "','" + txtName.Text + "','" + txtcontact.Text + "')";<br />
<br />
OleDbDataAdapter adapter = new OleDbDataAdapter();<br />
adapter.InsertCommand = new OleDbCommand(strCommand, conn);<br />
<br />
<br />
adapter.InsertCommand.ExecuteNonQuery(); <br />
conn.Close();<br />
<br />
{<br />
MessageBox.Show("Added successfully!");<br />
}<br />
}<br />
catch (Exception exc)<br />
{<br />
MessageBox.Show("An error occured :" + exc.ToString());<br />
}<br />
}
