Does anyone knows the API to set the mouse wheel 'number of lines' per scroll property?
I want to create a small exe program that changes it like the windows settings does.
Thanx.

class Class1<br />
{<br />
[STAThread]<br />
static void Main(string[] args)<br />
{<br />
WebRequest req = WebRequest.Create("http://www.google.com");<br />
<br />
WebResponse resp = req.GetResponse();<br />
<br />
resp.Close();<br />
}<br />
}<br />
Question is simple -> how come my code hangs on second line? I tried it on two computers (.NET 1.1) and it won't work. After some time I get WebException (The operation has timed-out).
Any help is greatly appreciated.

Use a HttpWebRequest to start with:
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://www.google.com");

Hi.Can anybody explain me how this function works cause Im trying to understand this code...
public static double[] convertPolyList(String theStr)
{
// initialize return value to unity
double[] theResult = {1};
// polynomials seperated by ']' characters
theStr = theStr.replace('(', ' ');
theStr = theStr.replace('[', ' ');
theStr = theStr.replace(')', ';');
theStr = theStr.replace(']', ';');
theStr = theStr.trim();
StringTokenizer theToken = new StringTokenizer(theStr, ";");
int index = 0;
for (index = 0; theToken.countTokens() > 0; index++)
{
double[] theArray = convertPoly(theToken.nextToken());
theResult = multiply(theResult, theArray);
}
return theResult;
}

Can you clarify your question?
It filters the string, removing opening parens and brackets, and replacing the closing ones with ';', then it removes all the spaces.
StringTokenizer iterates through the string, treating it kind of like a list broken up at the semicolons.

Is there some trick to using this method?
I looked up code samples and they are all just one line:
Environment.SetEnvironmentVariable(strName, strValue);
Yet when I do it, nothing is changed... I'm trying to modify the PATH variable by the way
|
|
|
|
|
[DllImport("Kernel32.dll")]
public static extern int SetEnvironmentVariable( string name , string value ) ;

It's integrated into VS2005, but I tried that anyway=).
importing that is the same as doing Environment.SetEnviornmentVariable()
|
|
|
|
|
|
Very odd...
Doing that I get an error on this line:
envObject["PATH"] = sPath;
Error reads:
Unable to cast COM object of type 'System.Management.WbemDefPath' to interface type 'System.Management.IWmiSec'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{2FD73A3B-64B3-480D-AEE9-54469D77123E}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

You realise the values will only be changed within your current process? And will not be persisted?
|
|
|
|
|
Then how do i Change the actual values? I've also tried changing them via registry and making a sendmessage call to 'update' them, but it didn't work.
|
|
|
|
|
|
I've tried a few variations of that SendMessage attempt...

I am writing a small Wx app and need to access a file on the HDD to fill a combobox.
I am using StreamReader and ReadLine to get it into the box. I have moved the file to the root, the file has no permissions set. Each time that I run the app it errors to the catch and tells me that it cannot find the file.
I have tried File.Exists( file ) and it also tells me that it is not there.
I have used @"c:\nex_tex.txt" and "c:\\nex_tex.txt" with no success.
If I didn't see it with my own eyes I wouldn't believe that it was there.
Anyway I am new to C# and obviously am missing something.
Thanks in Advance
DH

what do you mean with the file has no permissions set,
if it has no permissions set it won't be accessible to anybody.
|
|
|
|
|
Not read only, or hidden I meant. My mistake in words.

Are you sure? It really sounds like a permission problem.
Click the Advanced button in the security tab of the file properties. There you can see all permissions for the file.

If you don't have permission to access a file, the error message you get is that it doesn't exist.
This is commonly found when someone tries to make a web application access a file in a user folder, like for an example the desktop. As the web application is not run under the user's account it can not access files in a user folder.
I still think that it might be a permission problem, especially if you moved the file from some other folder. Then it might still have permission settings from the previous place.
Create a new folder somewhere that you know the application has access, put the file in the folder, and in the advanced security properties of the folder choose to replace all security settings of child objects. That will remove any specific settings on the file. Now try to access the file.

Hi!
Could it be that your Windows Explorer is hiding the extensions of known filetypes so that you're seeing "nex_tex.txt" as filename but the true filename is "nex_tex.txt.txt"?

I am using database which content are more than 100 000 rows.
In VB 6, with open data connection, I can view my data after 2 sec. but in C# .NET I am using DataSet but while data are loading to dataset it's take me 30 sec. and set DataGridView.DataSource = MyDataSet takes me next 10 .sec and waiting 40 sec. is too much.
Is posible using open conection in .Net and read only rows what I just need to view alike in VB 6?
DataSet is not just the best solution if you using large Database....
Or how to bind DataReader and DataGrid...?
Can any body help me with this problem... thx
