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.

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.

Vıkram.

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.

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 />
}
cheers,

Hi,
Thanx for your reply, but it still returns the same error. Tell me is this code compatible with c# .net 2005.

Although you can return a value from a call to ExecuteNonQuery, its slightly harder to setup as you must use output or return parameters from your query.
If you want to return a single value (say a 1 or 0 to indicate success/failure), you may find it easier to use ExecuteScalar. However, this returns a type called object which you must cast to an int (if that is what is being returned from the query)
Now, it is not clear from your code what t1 was supposed to return, but the sensible thing would be to return the new key from the table row just inserted. You could return 0 if the insert did not succeed and the rest of your code should then work fine.
I think @@IDENTITY works for Access for returning a newly inserted key, so your statement should change to:
string strCommand = "INSERT INTO compdata(ID,CompanyName,ContactName) Values ('" + txID.Text + "','" + txtName.Text + "','" + txtcontact.Text + "');SELECT @@IDENTITY";
then change:
int t1 = (int)adapter.InsertCommand.ExecuteScalar();
If @@IDENTITY does not work there will be loads of articles on the web about returning a newly inserted key.
