Have you tried this?
<br />
foreach (Object objActiveObject in _breathObjectHash)<br />
{<br />
if( objActiveObject is ActiveObjectsInLevel )<br />
{<br />
ActiveObjectsInLevel tmpObject = (ActiveObjectsInLevel) objActiveObject;<br />
ActiveObjectsInLevel myXml = new ActiveObjectsInLevel(tmpObject.Row,tmpObject.Column,tmpObject.ExistingObjects);<br />
myObject.SetValue(myXml,count);<br />
count++;<br />
}<br />
else<br />
{<br />
Console.WriteLine( "Wrong Type: " + objActiveObject.GetType().ToString() );<br />
}<br />
}<br />

hai Corinna John,
thanks for your comment.i tried the above.but always that else part only works so i triedthe following code and succeed.
foreach (Object objActiveObject in _breathObjectHash)
{
int index = objActiveObject.GetHashCode();
ActiveObjectsInLevel tmpObject = (ActiveObjectsInLevel) _breathObjectHash[index];
ActiveObjectsInLevel myXml = new ActiveObjectsInLevel(tmpObject.ObjectKey, tmpObject.Row,tmpObject.Column,tmpObject.ExistingObjects);
myObject.SetValue(myXml,count);
count++;
}
Regards,

Hi
In user32.dll there is a function called LockWorkStation.
Is there an complement to it??
Or is there any comparable in msgina.dll?
thx
|
|
|

|

Stefan, I think he wasn't searching for an equivalent, but for a complement 
I guess there's no reverse function to unlock the workstation.
Platform SDK states:
"This function has the same result as pressing Ctrl+Alt+Del and clicking Lock Workstation. To unlock the workstation, the user must log in."
Besides, what would be the point of LockWorkStation if you could unlock it programmatically?

If, by "complement", you mean is there a function to unlock the workstation, no there isn't. The user has to hit Ctrl-Alt-Del and login again. It can't be remotely unlocked for security reasons.

Hello folks,
I have never been in a project where I need to use legacy dll (non COM dll)
I looked at some examples from that I found in codeproject but I still have some question.
Suppose I have the following methods in my dll:
RF *rfOpen( const char *dev, int mode );
int rfTest ( RF *reader, char *namestr, int namesize, char *verstr, int versize );
where RF declared like this:
typedef struct rfreaderstruct RF;
struct rfreaderstruct {
HANDLE fh;
OVERLAPPED in_ov;
OVERLAPPED out_ov;
unsigned char buffer[BUFSIZ]; /* Read buffer */
int bufferPoint; /* Number of bytes used from inBuf */
int bufferCount; /* The number of bytes in inBuf */
char nonCommandBuffer[BUFSIZ];
int nonCommandBufferPoint;
int nonCommandBufferEnd;
int mode;
int requestInProgress;
int requestOutProgress;
int pendingWrite;
int pendingRead;
RFMessage rfmsg;
int responseState;
unsigned int responseDataCount;
RF *next;
};
how can I make them readable in .Net?
Thanks

If you never have to manipulate the members of the RF structure, it's pretty straightforward:
[DllImport("legacy.dll")]
public static extern IntPtr rfOpen( string dev, int mode );
[DllImport("legacy.dll")]
public static extern int rfTest( IntPtr reader, StringBuilder namestr, int namesize, StringBuilder verstr, int versize );For an 'out' string parameter, you should use a StringBuilder. Set the Capacity appropriately and pass that for the namesize parameter.
If you do have to manipulate RF directly, it will be a lot harder.

Hi,
does anybody know an opensource report generator like jasper reports written in C#?
I need the ability to show a print preview, send report to printer and create a pdf-document.
Or is it possible to integrate a java-program into a .net-program?
Thanks

You need to implement the IInputObject interface.

Thanks for reply Andy
after revieing source file from the proejct
http://www.codeproject.com/csharp/dotnetbandobjects.asp[^]
i found the following mehtods in Bandojectlib.cs file
public virtual void UIActivateIO(Int32 fActivate, ref MSG Msg)
{
if( fActivate != 0 )
{
Control ctrl = GetNextControl(this,true);//first
if( ModifierKeys == Keys.Shift )
ctrl = GetNextControl(ctrl,false );//last
if( ctrl != null ) ctrl.Select();
this.Focus();
}
}
protected override void OnGotFocus(System.EventArgs e)
{
base.OnGotFocus(e);
BandObjectSite.OnFocusChangeIS(this as IInputObject, 1);
}
protected override void OnLostFocus(System.EventArgs e)
{
base.OnLostFocus(e);
if( ActiveControl == null )
BandObjectSite.OnFocusChangeIS(this as IInputObject, 0);
}
How can i cal these methods so that it can enable BACKSPACE key in the toolbar?
kindly guide me please
Thanks

Check out this article from Microsoft. It's C++, but you should be able to convert it over.

Thanks for your reply
i visited the site and did find clue like
it was handled like that in C++ like that:
if (msg==WM_KEYDOWN) {
// on keydown, pass to edit as WM_CHAR
::SendMessage(hwndEdit, WM_CHAR, key, pMsg->lParam);
}
in Delphi i found the following:
function TDelphiBand.TranslateAcceleratorIO(var lpMsg: TMsg): HResult;
// Passes keyboard accelerators to the object.
begin
if (lpMsg.WParam <> VK_TAB) then begin
TranslateMessage(lpMSg);
DispatchMessage(lpMsg);
Result := S_OK;
end
else Result := S_FALSE;
end;
i coudnt find TranslateMessage and DispatchMessage in C#
neither i found SendMessage Equivalent in C#

I'm trying to pull a list of links from a webpage. I have everything working, but my problem is that if a url has an "&" in it, my code returns it as "& amp;" Here is a snippet of my code:
<br />
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(Url);<br />
webRequest.Timeout = 10000;<br />
HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();<br />
Stream responseStream = webResponse.GetResponseStream();<br />
string responseEncoding = webResponse.ContentEncoding.Trim();<br />
<br />
if (responseEncoding.Length == 0)<br />
{<br />
responseEncoding="us-ascii";<br />
}<br />
StreamReader responseReader = new StreamReader(responseStream, System.Text.Encoding.GetEncoding(responseEncoding));<br />
<br />
string html = responseReader.ReadToEnd();<br />
responseReader.Close();<br />
I know I can manually remove the "amp;" from the link, but I was hoping there was an easier way

HttpServerUtility has the UrlDecode method that will do the translation.
[edit]
Since it is a Url, you would think that UrlDecode is the right method, but & would be encoded in %xx format, so HtmlDecode might be the correct method.

Good day everyone!
i had problem in returning a DataReader object from a ServicedComponent class. The dataset object was return fine, but when return the DataReader, the datareader object was a transparent_proxy object. I dont understand why only the return DataReader object is a transparent_proxy?
And if i use any method of the returned DataReader, the following error will be occur:
This remoting proxy has no channel sink which means either the server has no registered server channels that are listening, or this application has no suitable client channel to talk to the server.
my codes is simplied as follow:
//First layer is DataAccess Layer
public sealed class DataAccess : ServicedComponent
{
//others methods here...
public OleDbDataReader ExecuteReader (OleDbConnection objConn, string
sql, CommandType commandType, OleDbParameters paramList)
{
//SomeOthers codes here...
return objCmd.ExecuteReader(CommandBehavior.CloseConnection);
}
}
//Second Layer is Data Access Logic
public class EmployeeDAL : ServicedComponent
{
public IDataReader GetEmployeesFirstName()
{
//someothers codes here...
DataAccess objDa=new DataAccess();
OleDbConnection objConn=new OleDbConnection();
return objDa.ExecuteReader(objConn,sql);
}
}
Thanks in advance for your help.

The DataSet and DataTable are designed for remoting, the DataReader is the fastest leanest class for reading data. It leaves off everything that isn't required like remoting support. Plus since it represents an open live connection, it isn't a good idea to do anything to extend the lifetime of the object. Ideally every data reader should exist in a using block. If you need data to live on past the connection, then use a DataTable or DataSet.

I've written a video jukebox that uses the Window Media Player as a control to play video/audio. The client has contacted their vendor for media, and they can get DVD quality files, but only if we write an algorithm for encryption, including coding per install, so they can provide a media file and it will only play on some installations of the software. Is there a way to access the streaming of WMP so that I can encrypt a file ( so that it's generally useless ), and make it play properly on WMP only within my jukebox program ?

I've only played around with it, but the DirectShow API is based on hooking filters together. So you would create a filter for your encrypted format and just hook it up to the wmp filter for playback. I think you need to handle a little bit more of the ui with this route, creating your own play/pause buttons, etc. But I don't think that is too much extra work.
Another option would be to write your own codec that wrapped the WMP codec, I'm not sure if that is possible, but it might be an option.
Another option would be to distribute the content in an encrypted format. On installation, they would be decrypted and stored using NTFS file system encryption. As long as the customer never got access to the account that the software ran under, they'd never be able to read the content. That way you wouldn't have to do anything special for playback, just during installation.

Can I use the DirectShow API to hook my own filter if I'm just passing videos to WMP ? I tried using Direct Show, in fact I wrote the whole system in DS9 before discovering that it's a buggy piece of crap.

That sort of thing appeals to me, because it would not create overhead during playback. Sadly, the vendor will not accept it.

I'm not sure. I only played with it long enough to research creating an AVI from a C++ DirectX application. I ended up using the crusty old multimedia Avi api because it was easier then hooking all the filters together.
How about using something like Cassini to host ASP.Net and access the files from a local web server. That way you can embed the encryption logic in your web server and you just send WMP the local url for the file. Another option would be to use an asyncronous protocol handler to keep the translation in process, but I'm not sure that WMP would support that.

I don't have any experience with this topic, but isn't it a classical use case for Windows Media DRM[^]?
