Hi
You might like to try using OOP[^] 
Create a class for each table. Include properties for each field, and the methods that operate on those properties.
Just a thought

Hello,
In my opinion, making a class for each table is not an optimal solution because a database might contain alot of tables, and it can expand also, which will increase the implementation cost and It may also result in code replication.
If generic methods for Addition, Update, Deletion and retrieval are deviced then it won't affect much as far as implementation is concerned. Developers will only need to add functionality to use newly added tables where ever it is required without implementing new classes for each table.
What you think?

Back to old good days it was done using FlashWindow Win32 API call. I'm sure there's a managed version of that function is around or at least you can use FlashWindow thru Platform Invoke.

Hi.Anybody can give me any hints where is my problem in this code...
using System;
public class Polynomial
{
// convert list of coefficients from input string
// to an array of doubles
public static double[] convertPoly(System.String theStr)
{
// obtain numerator coefficients from text field
theStr = theStr.Replace(',', ' ');
theStr = theStr.Trim();
SupportClass.Tokenizer theToken = new SupportClass.Tokenizer(theStr);
double[] theCoeff = new double[theToken.Count];
// load coefficients into array in reverse order
int index = 0;
for (index = theCoeff.Length - 1; index >= 0; index--)
{
theCoeff[index] = (System.Double.Parse(theToken.NextToken()));
}
return theCoeff;
}
// convert list of polynomials from input string
// to an array of doubles
public static double[] convertPolyList(System.String theStr)
{
// initialize return value to unity
double[] theResult = new double[]{1};
// polynomials seperated by ']' characters
theStr = theStr.Replace('(', ' ');
theStr = theStr.Replace('[', ' ');
theStr = theStr.Replace(')', ';');
theStr = theStr.Replace(']', ';');
theStr = theStr.Trim();
SupportClass.Tokenizer theToken = new SupportClass.Tokenizer(theStr, ";");
int index = 0;
for (index = 0; theToken.Count > 0; index++)
{
double[] theArray = convertPoly(theToken.NextToken());
theResult = multiply(theResult, theArray);
}
return theResult;
}
public static double[] multiply(double[] array1, double[] array2)
{
double[] theResult = new double[array1.Length + array2.Length - 1];
int outer = 0;
for (outer = 0; outer < array1.Length; outer++)
{
int inner = 0;
for (inner = 0; inner < array2.Length; inner++)
{
theResult[outer + inner] += (array1[outer] * array2[inner]);
}
}
return theResult;
}
public static void showArray(double[] theArray)
{
int index = 0;
bool first = true;
for (index = (theArray.Length - 1); index >= 0; index--)
{
if (!first)
{
System.Console.Out.Write(", ");
}
System.Console.Out.Write(theArray[index]);
first = false;
}
System.Console.Out.WriteLine();
}
// main entry point for test purposes only

Actually I do:
Standard question #1:
What do you mean by "not working"?
Standard question #2:
What error message do you get?
Standard question #3:
What does your code look like?
Standard question #4:
No, "nothing" never happens. Exactly what is happening?
Standard question #5:
No, that is not the code you are using. It can't produce that result. What does the code you are using look like?

b { font-weight: normal; }

My company is currently creating a prototype GUI in C# which accesses data in our old codebase (C++) through COM. We have things working pretty well, but have stumbled upon a very strange error, which I was curious if anyone else had run into as well.
After loading our C++ application through COM, I have some xslt files I'd like to transform. I can create XmlDocuments, XmlTextWriters, etc. all perfectly fine, but when I try to use the XslCompiledTransform.Load() function, the compiler just quits. There are no debug message of any sort, and I can't step into the method to see what it is trying to do. I've trying using every possible type of input parameter for the Load() method (string path, XmlDocument, etc.) and none of them seem to make a difference.
I know that something strange must be happening after we load our objects through COM, because if I create the XsltCompiledTransform class and load xslt files before the objects are loaded through COM, things work just fine. I've searched the web, and could not find this issue anywhere else. Any advice on this matter would be appreciated, and if more explaination is needed please let me know (I typed this up really quick, just heading out of work for the day). Thanks in advance.

HI.
I'm creating a dinamic image that types something with a spetial font. Of course, I have the font not installed on the server fonts dir, so I have to use it with a PrivateFontCollection.
My problem is that the code works in my local server (where I also don't have the font installed on my fonts dir), but when I uplad it to my host, it renders the text in arial, not on my font.
any ideas?
here's the code:
<br />
Bitmap oImage = new Bitmap(400,50,PixelFormat.Format32bppArgb);<br />
Graphics oGraphics = Graphics.FromImage(oImage);<br />
<br />
MemoryStream streamMemory = new MemoryStream();<br />
<br />
oGraphics.Clear(Color.Transparent);<br />
<br />
Color cInk = Color.FromArgb (127,0,0,0);<br />
<br />
Brush oBrush = new SolidBrush(cInk);<br />
<br />
PrivateFontCollection pfc = new PrivateFontCollection();<br />
pfc.AddFontFile(Server.MapPath("Mael____.ttf"));<br />
FontFamily family = pfc.Families[0];<br />
Font oFont = new Font(family, 28);<br />
<br />
<br />
oGraphics.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;<br />
<br />
string sText = "";<br />
try {<br />
sText = (Request.Params["Text"]);<br />
}<br />
catch{}<br />
<br />
oGraphics.DrawString(sText, oFont, oBrush, 1, 1);<br />
<br />
Response.ContentType = "image/png";<br />
<br />
oImage.Save(streamMemory, ImageFormat.Png);<br />
<br />
Byte[] buffer = streamMemory.ToArray();<br />
Response.Clear();<br />
Response.OutputStream.Write(buffer, 0, buffer.Length);<br />
<br />
Response.End();<br />
streamMemory.Close();<br />
oGraphics.Dispose();<br />
oImage.Dispose();<br />

Hi. Iam developing some app and for security reasons I want to disable running that app on certain computers.
I can do that by checking the hdd id. Is there any better way, because hdd is much more replaceable than CPU?
Sample:
Some user logs first time on to that app over the net. Program saves the hdd id into the database.
Next time user logs, app checks hdd id previously saved in database and if it's equal, then the user can be logged.

If you want to output to excel then the easiest will be in the CSV format (this will not apply any formatting). And RTF for Word likewise.
If you do want the special features of Excel and Word then Aspose have some components for creating and opening Word and Excel files.
Alternatively if you want a freebie then I'm sure (I seem to remember coming across them) there are articles on CP about how to do this.
Another alternative is to look into the Word and Excel XML formats (Office XP onwards), this may be the simplest option unless you can find an article on how to do it another way on CP.
