This is nowhere near enough information to diagnose your problem.
Your code is either running from a network share, in which case, it'll be running in a more security-restricted sandbox, or your code is trying to do something where the user doesn't have sufficient rights to whatever resources your trying to get at.
Without knowing more about your code, the failing code snippet would help GREATLY!, and the environment it's running in, it's impossible to tell what's going on.

this.InvokePaint(grdExpenseSheet, myPaintArgs);
myPaintArgs = new PaintEventArgs(e.Graphics, new Rectangle(new Point(500, 300), this.Size));

How do you map TimeStamp (SQL Server) to DateTime (.NET) datatype? I ran into the following error:
"Could not cast the value in field ts_times4_ to the Type TimestampType. Please check to make sure that the mapping is correct and that your DataProvider supports this Data Type."
My table:
CREATE TABLE [some_table] (
[field1] [int] NOT NULL ,
... other fields ...
[ts_timestamp] [timestamp] NULL ,
.... other fields ...
) ON [PRIMARY]
My class:
Namespace ....
Public Class AtDivision
... other properties ...
Protected _timestamp As DateTime
' How do I map to data type 'Timestamp'?
Public Property Timestamp() As DateTime
....
End Property
End Class
I tried this in my mapping file, but, ran into the error I mentioned...
property name="Timestamp" column= "ts_timestamp" type="Timestamp"
Thanks in advance!

Not sure about how nHibernate handles this, but a SQL timestamp is a .NET byte array.

I'm having a VERY hard time finding material I can read to understand this stuff. So far I got a program to evaluate mathematical equations and a basic Lexer that splits a string simply into a stack like so...
Example string - FunctionName ( "Param1" );
Stack[5]SEMICOLON
Stack[4]CLOSE_PAREN
Stack[3]"Param1"
Stack[2]OPEN_PAREN
Stack[1]FunctionName
Basically it tells me when it hits a special character, and after that it tells me what's inside it. I'm having a really hard time explaining this, a bunch of source is available here:

Thanks

But what are you needs? Do you need to write a parser/lexer or is it a homework assignment where you need to understand how it's done?
If all you need is to write a quick parser, try COCO/R or ANTLR.

(I'm replying from school right now)
I'm only 16, not in college quite yet, so it's not an assignment 
I've realized these easier solutions, but I want to hardcode it (for fun). The documentation on this is geared towards people already very well versed in computer science and such. This is a bit out of my league, so I'm going to ask that you link me to a bit of less-savvy-specific material

I have written 2 jagged arrays to a binary file using the following code:
string path = "c:\\question.dat";
BinaryWriter binaryOut = new BinaryWriter(new FileStream(path, FileMode.Create, FileAccess.Write));
try
{
for (int i =0; i < questionData.Length; i++)
{
for (int j = 0; j < questionData[i].Length; j++)
{
binaryOut.Write(questionData[i][j]);
}
}
for (int i = 0; i < repsonseData.Length; i++)
{
for (int j = 0; j < responseData[i].Length; j++)
{
binaryOut.Write(responseData[i][j]);
}
}
binaryOut.Close();
}
catch (System.NullReferenceException)
{
binaryOut.Close();
return;
How do I read the data back into the jagged array??
questionData is type String and responseData is type Bool.
Could you please help me with the code..

Seeing as your array sizes are not always the same, shouldn't you be writing the length first, so you know how much reading you need to do ?

Thats a good point. I can see how to do it now.

Hi, ive just created a custom control following one of the tutorials here. It was great, but as soon as i add in support for the "DesignerAttribute" it stops my control from non-transparent and selectable by clicking anywhere in the control at design time.
If i uncomment the line:
[DesignerAttribute(typeof(GridDesigner))]
Then the control appears as a grey square, and allows me to select it by selecting anywhere in that square.
However, if i leave the line in, it goes transparent so i can see the design grid and i can only select it by clicking on the border.
Does anyone know why this is?
Thanks

Sorry, got that slightly wrong.
With "DesignerAttribute" set, i can only move the control by dragging the border around.
Without it set, i can move it by dragging anywhere inside the border.

Hello,
I encountered a strange problem and I do not know what is causing it.
I created an empty form, added a tabs control to it and set the tab control
dock style to fill. Then I added three tabpages to it. To the first tab page
I added three buttons. The first button's click handler would set the tab
control's tab alignment to TabAlignment.Left and the second buttons click
handler would set it to Bottom.
I added mouse enter and mouse leave handlers to the third button. Whenever
the mouse would enter or leave the button, I would use Debug.WriteLine to
write a message.
Now, when I start the form, the mouse enter/leave events work great and
everything is fine. However, once I change the tabs alignment by hitting one
of the first two buttons, the third button no longer fires it's mouse leave
event. The mouse enters and mouse enter fires correctly, but it seems that
the mouse leave event has been unregistered when the tab control's tab
alignment changed. Also, when I enter the button again, the mouse enter
event is not fired.
Does anyone know what can be causing this behavior?
Thanks,
-Flack

Hi,
I am writing an SQL Server database application and I have noticed that under Management there are some database locks from my application. I don't think this is a good thing and want to make sure I am releasing the connection properly.
How can I do this?
At the moment I am doing this.
connection.Close();
connection.Dispose();
connection = null;
Is this enough?
Thanks
Stephen

It's enough to use Connection.Close() method.
About the locks, what kind of queries do you use?
|
|
|
|
|
Hi,
The queries are all SELECT, INSERT, DELETE and UPDATE queries.
Thanks
Stephen

Do you use any Transactions?
If so, you may want to add WITH (NOLOCK) to your select's used within the transaction

Anybody got any ideas on how to parse a resume form a word documnet. Basically the asp.net form would required users to upload word document, the webserver would then use ms word to open and save as text or xml. I would like to figure out a way to parse out name, address, phone etc...
I've tried saving it as a ms xml but have not had any success figuring out what's my next step. even if somebody had an example in javascript , c# or vb.net
thanks

Letting upload user their resume and then parse them would be difficult as each user might have different format of resume. The best way is to have all fields input by user rather than upload resume. User could easily copy and paste resume content in your input fields like name, address, phone or work history.

I have a mesh that I generated from the Mesh.TextFromFont method. I would like to center its axes so that when I rotate the mesh along the Y axis, it rotates around the center of the object instead of the beginning of the 3d text mesh.
How can I center the axes of a mesh object in such a case in Direct3D? 
John 3:16: "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life."

What I would do is create an invisible parent object, add the text mesh to the parent, so that any transformations done on the parent will get done to the child. Offset the child's position in the parent appropriately, then rotate the parent.
