MSDE 2000 Insance Invalid

OK, I'm trying to reinstall MSDE 2000. Used control panel->add/remove programs to get rid of the last one.

But no matter what isntance name I use in the setup ini file (or command line) I get the error "The specified instance name is invalid."

Any ideas?

.Net Remoting and WebClient memory trouble...

Hi everyone…

I am using .Net Remoting (C#). I need to use a WebClient do get an image from a URL. I need to constantly retrieve the image, therefore I have the code in an infinite loop (within a thread). The thread sleeps for ½ a second.

The code runs fine if I run it without using Remoting, however when I use Remoting the program uses up all the memory on the server!

I have stripped the code of all complications. Basically all the thread does it:

System.Net.WebClient webClient = new System.Net.WebClient();

webClient.DownloadData(URL);

And then it sleeps. But as I say, this uses up all the memory resources?

I then moved the code into a console application that does the webClient.DownloadData(URL) call, then it calls a method on the remote object to pass it the data. But I ended up with the same problem, all the memory got used up? Sniff | :^)

Please try using the web client, within a continuous thread, and within Remoting.

As soon as I mix Remoting and the WebClient, the memory gets used up. The page file usage sky rockets! Frown | :(

Am I missing some obvious flaw with trying to use Remoting and a WebClient together? D'Oh! | :doh:

Can anyone offer me some advice????

MSDE 2000 connection error

I posted a couple of messages on this topic last month. I got a lot of great help and suggestions, but after taking the time to implement all of them I'm still not able to connect to my database over the network.

Using the CodeProject tutorial: "Hands on how to configure the Microsoft MSDE" I just did a fresh install of MSDE 2000 enabling networking and using windows authentication. The instance is DomBenBSA running on computer DB-NGIVENS. I accidentally killed my testing database, but I recreated it and attached it to the server: it's BenefitSelectDB.

So now I have the server running and I go to my laptop. I'm logged onto the domain (DB) with my standard login (NGIVENS). I'm using RapTier to try and connect to the database (it's just faster than running test C# connection strings).

I can detect the server (DB-NGIVENS) - which is more than I could do before - but when I try to get to the database I get this error (when i'm using Windows Auth):

[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.

Here's the interesting thing. I go back over to the host machine where I have the server installed and check out my list of users. I don't see myself anywhere. So I add the user 'DB-NGIVENS'. When I try that, I get this error:

Msg 15063, level 16, State 1, Server DB-NGIVENS\DOMBENBSA, Procedure sp_grantdbaccess, Line 116
The login already has an account under a different user name.

So now I'm confused. If the login already has an account under a different name - how can I logon from another computer where I'm logged in as myself?

Any help would be SO appreciated.

(By the way, here are the users that I do find:

db_accessadmin
db_backupoperator
db_datareader
db_datawriter
db_ddladmin
db_denydatareader
db_denydatawrier
db_owner
db_sercurityadmin
dbo
guest
public)

Select ListView Item on KeyPress

I am looking for a way to autoselect ListView Items on Key Press event based on the sorted column.
The behaviour should be similar to Windows explorer.

If one types the keys very fast the keys should be buffered and the buffer string should be compared with the sorted column. If the speed is slow, the buffer is cleared.

Can somebody guide me to some article on this? I tried to google but to no avail.

I know this is available on of-the-shelf ListView. But this works only for the first column.
I need this on the sorted column.

Don't have an article for you, but here is a basic implementation description:

Handle the KeyDown event for the appropriate control.
  If the last key press was not within the timeout period,
    then clear the "keys pressed" buffer (maybe a string builder).
  Add the typed key to your "keys pressed" buffer.
  Reset the keydown timer to the current time.
  Perform your comparison to select the appropriate item.

Selecting an item is very straightforward, so that shouldn't be much of a problem. If you're not sure how to do the comparing, you can do it easily by looping through the items list and comparing the substrings manually.

Stretching a polygon side in C#

20-Sep-05 3:52

Hi,

I am drawing a three sided polygon. I declared a ArrayList variable. On mousedown i am capturing points and adding the same to Arraylist variable.

After that i am drawing lines by reading points from the Arraylist variable.
while drawing the lines i am setting the lastline lastpoint to the nextline firstpoint.

My lastpoint and firstpoint will be same meaning when i am closing the polygon i am drawing line from the thirdpoint to fourthpoint(which is same as firstpoint).

I am trying to drag the secondpoint and thirdpoint. that works fine. but if i position the mouse on the firstpoint and if i tried to drag it is not stretching by combiningthe firstline and lastlines together instead only the firstline is getting dragged.

Can anyone help me.

Thanks in advance, Beginner

Take a look at the System.Drawing.Drawing2D.GraphicsPath class. You can do something like this:

System.Drawing.Point pts[] = new Point[3];<br />
System.Drawing.Drawing2D.GraphicsPath gp = new System.Drawing.Drawing2D.GraphicsPath();<br />
<br />
gp.AddPolygon( pts );<br />
gp.CloseFigure();<br />

According to which points you select and drag, you would need to recompute the points in the pts[] array then regenerate the GraphicsPath.

I hope this helps.

Programmatically showing and hiding a scollbar in a multiline textbox

Is this possible?

The default is a visible, but grayed out scrollbar.

There doesn't appear to be a way to define this behavior using properties, and the textbox.Lines.Length property returns the number of logical lines, not the number that are/would be displayed due to word wrapping.

override Paint method for DataGrid

Hello, I have this simple Paint method for my datagrid:

protected override void Paint(System.Drawing.Graphics g, System.Drawing.Rectangle bounds, CurrencyManager source, int rowNum, System.Drawing.Brush backBrush, System.Drawing.Brush foreBrush, bool alignToRight) <br />
       { <br />
          DataRowView view = (DataRowView) source.Current;<br />
          System.Drawing.Color myColour = Color.White;<br />
          numberFormatInfo = new NumberFormatInfo();<br />
	      numberFormatInfo.CurrencySymbol = "$";<br />
	      numberFormatInfo.NumberDecimalDigits = 0;<br />
	      numberFormatInfo.CurrencyDecimalDigits = 0;<br />
	      numberFormatInfo.CurrencyNegativePattern = 1;<br />
          <br />
          string[] str = view.DataView.Table.Rows[rowNum]["IndentLevel"].ToString().Split('~');<br />
          <br />
// HERE IS THE PROBLEM--------<br />
/*<br />
          if (rowNum < 4) {<br />
             this.Format = "n";<br />
             this.FormatInfo = numberFormatInfo;<br />
          } else {<br />
             this.Format = "c";<br />
             this.FormatInfo = numberFormatInfo;<br />
          } <br />
          */<br />
          <br />
          <br />
          <br />
          // --- Main Heading ---<br />
          if (str.Length == 1) {<br />
             myColour = Color.Coral;<br />
          } else if (str.Length == 2) {<br />
             // --- Sub Headings ---<br />
             if (str[1] == "1" || str[1] == "4") {<br />
                myColour = Color.PaleGoldenrod;<br />
             // --- Net Sum Headings ---<br />
             } else if (str[1] == "7") {<br />
                myColour = Color.Lavender;<br />
             // --- Other Headings ---<br />
             } else {<br />
                myColour = Color.Wheat;<br />
             }<br />
          // --- Populated Rows ---<br />
          } else if (str.Length == 3) {<br />
             myColour = Color.SeaShell;<br />
          } else {<br />
             myColour = Color.Thistle;<br />
          }<br />
		  <br />
		  // ----------------------------<br />
		  // ------ Paint the Row -------<br />
		  // ----------------------------<br />
          try{ <br />
             backBrush = new SolidBrush(myColour); <br />
          } <br />
          catch(Exception) {} <br />
          finally {<br />
             base.Paint(g, bounds, source, rowNum, backBrush, foreBrush, alignToRight); <br />
          } <br />
       }

So, the commented out portion couses the datagrid to flicker, if it is inserted in the code, and other controls like buttons, etc.. don't show up on the form, unless you move the form. If it's commented out, everything is working smooth and fine. Any ideas?

Thank you

Dialog box exit

I have a modal dialog box with AcceptButton & CancelButton

Is there a way to test if the dialog was closed with the user pressing 'Enter' as apposed to using the mouse to click either of the buttons or the control box?

MyDialog dlg = new MyDialog();
DialogResult rc = dlg.ShowDialog();
if(dlg.wasEnterPressed()) ...

The 'Click' event on the AcceptButton fires for both mouse & keypress.
I tried to look at the KeyDown event but that doesn't fire when 'Enter' is pressed.

Re: Dialog box exit

Ashok Dhamija20-Sep-05 3:22

As you have an AcceptButton, it appears that the Click event of the OK button precedes the KeyDown event for the Enter key and kills the dialog box before the KeyDown event fires. Try NOT declaring the AcceptButton and then see whether the KeyDown event fires for the Enter key.

Ashok Dhamija

The solution I went with was to add:

{
if(k == Keys.Enter)
bEnterPressed = true;

return false;
