Agreed.
I interpreted the question as asking how to determine if iexplore.exe was executing. If the question is "How do I tell if any 'IE' components are currently hosted?" in a process started by explorer.exe, for instance, it would be a more difficult task to determine how much "IE"-ness the explorer.exe process displayed (searching the associated modules blah blah blah).
Thanks for the clarification.

Use property ModuleName
Process[] ProcessList = Process.GetProcesses();
ArrayList ProcessNames =new ArrayList ();
foreach(Process myProcess in ProcessList)
{
String myString = myProcess.ProcessName ;
string myModuleName;
try
{
myModuleName= myProcess.MainModule.ModuleName;
}
catch
{
myModuleName = "no name available";
}
Console.WriteLine(myModuleName);
}

Hi people,
Can you tell me is there any real difference between:
IMyObject obj = (IMyObject) otherObject; and
IMyObject obj = otherObject as IMyObject;
Thanks

Hi,
I have a WinForms program with an IE browser object (AxBrowser) hosted within my program which I cast the loaded document as IHTMLDocument2 to use the MSHTML editing features.
Problem is that I cannot stop the IE object from asking (before navigating to another doc) if I want to save the document if it has changed. Does anyone know which interface within MSHTML i can use to intercept this dialog and suppress it.
Thanks in advance

in My C/S WinForm program, Client contacts with Server using Socket.and Both of them written in C#.
i want to modify the C/S mode to B/S mode because i dont want to install a WinForm program at client. i would like to implement the same function at client using Browser.
i need drawing graphic/winform controls and many others.
do there have good solution in this case ?
And aslo i dont want to install CLR at client.

C/S ?? B/S ??
By this do you mean Client/Server and Browser/Server? If so, you do know that a browser is just a type of client.
If you don't want to install the CLR on the client then you cannot draw graphics and WinForm controls on the client.
If you want to convert your client code to be usable in a browser you are going to have to re-write the client as an ASP.NET application and host it on a server. The major architectural difference between ASP.NET applications and WinForms applications is that ASP.NET is stateless which means that your presentation layer cannot be ported easily and you will need to think about re-designing how it interacts with the user.

Hi,
I'm using the function drawString, and if i'm using the font "Microsoft Sans Serif" with fontStyle.Bold, it crashes and I get the exception " A generic error occurd in GDI+ ".
The code:
I'm calling the DrawString function from the printDocument.
private void PrintFormComponents(System.Drawing.Printing.PrintPageEventArgs ev)
{
ev.Graphics.DrawString(lineText, printFont, textBrush,point , new StringFormat));
}
the printFont is "Microsoft Sans Serif" ,10,fontStyle.Bold
Thanks,
yonit

What StringFormat are you actually using? Your sample code above uses new StringFormat with no parens, so that can't be it (perhaps you just forgot them and didn't copy and paste or anything). You might try using a typographic format, like the static StringFormat.GenericTypographic property, instead of just new'ing up a StringFormat.
A quick search on Google yields no known bugs using "Microsoft Sans Serif" and Graphics.DrawString.

Hi there!
A question for all folks that are using WeifenLuos DockManager (which I have to shortly intend is great!):
I've got two panes in my application. One is docked at the left and one has the state DockState.Document. I've got a couple of different DockContent derived Forms in this DocumentPanel. Depending on the users selection, I hide or show some of them using the appropriate functions Hide() and Show() of the DockContent deriatives.
Problem I'm having is that the documentPane (and it's Content windows) start flickering crazily. I've tried to ResumeLayout() and SuspendLayout() do supress layouting but it won't help. Goal is to supress any repainting until I'm set. Any ideas?
Thanks in advance!

The best place for this question is on the discussion board under Weifen Luo's article, here[^]. He keeps it up to date and is the best person to ask about issues like this. It's also possible that it's a known bug and he just doesn't have a fix for it yet.

hi, i have a counter that counts down from 5 minutes. i have 2 separate displays: 1. minute display(which counts down every 60 seconds), 2. seconds display(which counts down from a minute i.e. 00, 59, 58 ....). what i cant figure out is how to make the second counter to restart at 00 after a minute has gone by. can anyone help me? thanks.
Sincerely,

Why do you need two counters?
Why not just have one counter counting the seconds?
Assuming your counter variable is called counter, each time the timer fires you increment it. To get the seconds and minutes try:
int seconds = counter % 60;
int minutes = counter / 60;

i have a custome encrypt program for a foxpro database i have so i converted the program to csharp it encrypts data to and from a table but when i encrypt it using csharp i can't decrypt it because the charter maping in csharp is diffrent i think because i can encrypt the letter "a" using my method but i can't read it from the table in its encrypted form and turn it back into a "a" so can somebody help me
here is a copy of a method that dose basicly the same thing as the encrypt program i am trying to use the idea is the same and i can't change it because we have hundreds of programs that use this method to encrypt and decrypt data in these tables
public string encrypt(char[] txt)
{
int length=txt.Length;
int char_num;
StringBuilder result=new StringBuilder();
char[] out_array=new char[length];
double x,y,num;
for(char_num=1; char_num<=length; char_num++)
{
x=(double) txt[char_num-1];
y=0;
for(double bit=7;bit>=0;bit--)
{
num=(int) Math.Pow(2,bit)-1;
if(x > num)
{
num= Math.Pow(2,bit);
x=x-num;
num= Math.Pow(2,7-bit);
y=y+(num);
}
}
out_array[length-char_num]=(char) y;
}
for(char_num=0; char_num

Why can't you? An array of characters is an array of characters. Taking away the storage of a character array in memory, every language pretty much treats an array of characters the same.
Apparently, you store this in a table field as a sequence of characters, so that's what you get back, correct? So why can't you decrypt this? You're using a two-way hash (not very good encryption at all, but perhaps good enough for your requirements) so if you apply the hash algorithm in reverse on the ciphertext you end up with your plaintext.
If you're having problems with the decrypt method, I suggest you post it here.
Also, I noticed you have this declared as an instance method. Encrypt and Decrypt (notice the casing, too, which is consistent with the recommended .NET naming conventions) would probably work better as statics. I mean, unless you're encapsulating functionality into the containing class, these two methods are really more procedural. Just a suggestion.

that is just a quit encrypt method i wrote to post on this web site and i know there are better ways to encrypt but this was written in foxpro 2.0 for dos and there are still about 500 programs that use it in my company just have not got around to changing it but i can use this program to encrypt text from a text box and put it back in the textbox and when i run it again it decrypts but as soon as i store it to a table it changes ther charter set to where i can't decrypt it
on and that encrypt method is my decrypt method too its just for testing

ok let me explain what i tried i encrypted my name "chad" to a textbox and i cut it from the textbox and pasted it in a foxpro table after i pasted it there i cut it again from the foxpro table and pasted it back to a csharp from and tryied to decrypted it and could not and just to make sure i did not do anything wrong i also copy there encrypted text from the csharp form and trying to decrypted it and it works fine
as soon as i past the encrypted text into foxpro it changes the charters and it only seems to change charter from 128 and above can you help me fix this

Now that's handy to know. The text encoding for that field in FoxPro is incorrect. .NET stores and operates on Unicode text natively. What FoxPro has defined for that field is ASCII, which is only characters 127 and below. A codepage (and different regions, countries, and makers have their own) defines the rest of the characters.
What you need to do is change the encoding of that field to UTF8 (like ASCII, but allows for 2-byte characters above 127, making it a good replacement for ASCII on older systems in order to support Unicode as well) or to Unicode (either UCS2 or UCS4).
The other option is to base64-encode the text so that only ASCII characters are used (thus not requiring a change in the FoxPro database). You can do this simply over the byte[] that represents the ciphertext (which is binary anyway - not text!) using Convert.ToBase64String and Convert.FromBase64String. Base64 is the common encoding used for ciphertext (encrypted text) because it's fairly compact and can easily represents arbitrary bytes.

ok foxpros codepage is 1252 and it dose allow for characters above 128 it is double-byte characters
what else could i try

As I asked before - are you encoding the encrypted byte[] array (which the .NET crytography classes create) as text? You have to use hex, base64, or some other encoding to save the cipher data as text. It is not enough to use Encoding.GetString, since many of those bytes are unprintable (and therefore can't be copied and pasted - something you said you're having problems with). Why do you think that notepad.exe displays tons of "funny" characters when you open a binary file (like a .dll or .doc)? It's not text - it's binary.
Trust me - I've been working with cryptography long before .NET. You must encode it as text that can be stored correctly, which is why I mentioned Convert.ToBase64String and Convert.FromBase64String. There's also several articles here on CodeProject and replies in this message board about saving cipher data as hex-encoded (base 16) strings. Both are pretty easy to do.

how to capture image from media player video?

Hi,
I have a table (ms access db) that has dates in each row. I want to be able to fill a dataset with records that fall within a date range. I'm using two dateTimePickers (win form) for start and end dates. How would I go about this? Should the dates in the access db be formated as date/text/number? Thanks for any help you can give.

Found it,
I was able to use the sql code below and have it work... don't know if it's the best or not. Didn't seem to matter if the date was text or Date DataType in db file.
SELECT * FROM Orders WHERE OrderDate>=? AND OrderDate<=?

See if the manufacturer of your video setup has an SDK available and use that. Otherwise, you can use the Windows Media Capture 9 suite, which you can get here[^].
