Thankyou Ravi.
I have already been to the links the you have specified.I have also implemented canny edge detection in vb.net but the results are not good, meaning the edges are not thin (preferably a single line of pixels).
Is there some way to do that? Non maximum suppression is not very helpful. If you know how to track the edges please help.It's urgent.

Sorry, my knowledge of image processing resembles the null set. 
That being said, have you seen the Rothwell[^] method? Any better than Sobel and canny?

I'm not even sure how to ask this but i've got a problem that has me stumped and i'm hoping someone can shed some light on it.
I've got a winform application written in c# 2.0 that has most of it's content and controls wired to a remote sql server 2000 database. now there is one specific control tha is acting weird on another computer it's a standard NumericUpDown Control when the form it belongs to is shown it's min and max value as well as it's current value are set based on criteria from the main form. now i've run the program on windows xp, xp 64 and server 2003 enterprise on my computer and it works fine in all of them. but when i took it to the computer it was supposed to be run on after the install ran it installed the .net framework and registered everything with caspol. Now once the program is run and everything else works fine but when the form with the numericupdown control is loaded the numericupdown control has some arbitrary negative number passed to it like -17 or -16 and i have no clue why it would do that on one xp pro machine and not on another.
Anyway i hope someone can at least point me in the right direction
Thanks

Dear all,
I am trying to get the target location data a shortcut file on a desktop. I managed to get to the desktop using Environment.GetEnvironmentVariables() and can retrieve the shortcut file but can not find the way to retrieve the target location. Could anyone please help? Thank you!

If you use Shell interface function CreateShortcut with name of existing link as argument - created WshShortcut object will be filled with shortcut information.
sample:
IWshShell ws = new IWshRuntimeLibrary.WshShell();
string shortcutFile = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Desktop) + "\\" + "ToDo.txt.lnk";
IWshShortcut sc = (IWshShortcut)ws.CreateShortcut(shortcutFile);
after that sc.TargetPath will contain link target. Of course, if you have ToDo.txt shortcut on your desktop .
Don't forget to add reference to %system32%\\wshom.ocx and add "using IWshRuntimeLibrary;"
Hope that helps.

Thank you very much for your reply.
The shortcut files already exist on the desktop so I just need to read? the file property
to get the target location. I have looked at IWshShortcut before and only found how to create a shortcut file.
Unless ws.CreateShortcut(shortcut) works for existing shortcut files too?
Thank you !

I think my mistake 
(IWshShortcut)ws.CreateShortcut(shortcut) doesn't create a shortcut file on the desktop.... silly me.
Thank you for your help!!!

I have a Service which is installed already. If I need to change the startuptype of the service how Can I do that using C#?
I know that before Installing the service we can set the starttype property to set the StartType as automatic or manual. But after installing the service if want to change how should I do it?
Thanks

Hi,
I am currently working on a application that generates faxes from mail merged documents (Word and Excel datasource). Everything works fine. Except the client has an habit of creating the mail merge document with all the information in word 2003 Textbox. (Including the mail merge field). I use C# to do the mail merge and so far i have not found any way of reading these fields. (The text boxes are termed as Shapes in the Word API, so far I havent been able to find how to access anything inside a Shape).We have already decided to tell the client to take the Mail merge fields out of text boxes so that the Word API can read them.
But i want to be absolutely sure that there is no way to read them before i request the client to make an process change. If anyone has encounted this issue before please advise.
Thanks Kalyan
Word.ApplicationClass wrdApp;
Word.Document wrdDoc;
wrdApp = new Word.ApplicationClass();
object docuFile = this.lblDocSrc.Text;
wrdDoc = wrdApp.Documents.Open(ref docuFile, ref oMissing,ref oMissing,ref oMissing,
ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,
ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing,ref oMissing);
foreach(Word.Field myField in wrdDoc.Fields)
{
myField.Select();
if (!DocFields.Contains(myField.Result.Text.ToString()))
{
DocFields.Add(myField.Result.Text.ToString());
}
i++;
}

Hello,
If I use the tab to go through the datagridview it is added automatically a new item.
Here I use the ListChanged Event and ItemAdded to Update another internal list. To hold the list up to date I have to remove also the items when a row is removed.
When I have made no changes to the Item and I press in the last cell another time the tab key the last row is removed, and after that another time added. But now I have the problem that I can't find any event which happens before the row is removed to hold my list uptodate...
Has anyone an idea?
Regards
Hansjörg

Hello,
I have a problem with inserting into a table. I can read from it, but no updates or inserts.
This is the code i wrote:
string connectionString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\\Planning.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";
string queryString = "INSERT INTO registratie(userid,clientid,taskid,unitid,date,start,stop,description) " +
"VALUES(2,1,1,1,GETDATE(),'08:08','09:00','bla bla bal ...') ";
SqlConnection connection = new SqlConnection(connectionString);
SqlCommand command = new SqlCommand(queryString, connection);
try
{
connection.Open();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
try
{
int test = command.ExecuteNonQuery();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
MessageBox.Show("QUERY: " + queryString + "\n inserted !!!");
connection.Close();
}
Can someone please help me?
thx

do you get an error message?
When you look in the quickwatch: what does the 'queryString' variable have as value?
Coulda, woulda, shoulda doesn't matter if you don't.
|
|
|
|
|
I don't get an error message, that's the problem.
I don't really understand what you mean with quickwatch, but if you mean what the output is at the end it gives:
QUERY: bla bla inserted
When I do this query directly with sql in the database it there is no problem.
Regards
William

No what I meant was: in debug mode (set a breakpoint)
If the variable is assigned hover over the variable with your cursor, right-click and choose quick watch.
You'll get a dialog with some info. The cool thing about quickwatch is that you can alter the data or see entire objects.
Coulda, woulda, shoulda doesn't matter if you don't.
