that is,the document i am storing in the database contain some informations about some peoples when the user gives like "games" in the textbox and clicks search button it will search for the word "games" in all the word document that are present in the db(,if it present) then the entire detail of the all matched records will be displayed in the grid(like name,age,etc..).here i use the like query for this search (ie) "select * from tab.name where skill like games"

Exactly how do you store the decuments in the database? If you would store the documents as binary data, you wouldn't be able to search them like that.
How do you need to serach the information? Do you need a free text seach, or are you only going to search for specific keywords? If the later, then I would suggest that you extract the keywords when you create the record, and store the keywords in a separate table, so that you can make a much more efficient query.

This approach was obviously flawed from day one. You need to read your word docs to search them, your database is an extra overhead, and not the tool it should be. You need to store keywords with your word doc if you want efficient searching.

Hello,
I set the TypeConverter attribute of a class named MyFilter to typeof MyFilterConverter derived from TypeConverter.
[TypeConverter(typeof(MyFilterConverter))]
public class MyFilter
{
}
public class MyFilterConverter : TypeConverter
{
}
My executing assembly gets access to it by dynamically loading an assembly containing these 2 classes.
Eveything works fine as long as the executing and the dynamically loaded assembly are in the same directory. If this is not true the TypeConverter attribute will be ignored - easily proved by setting MyFilter as selected object in a property grid.
string fp = FILEPATH_FOR_DynamicLoad;
Assembly assembly = Assembly.LoadFrom(fp);
I would really appreciate if someone could help me out.

I have seen something similar happen in the past with attributes disappearing, but I cant recall the details now. And no, I never did find a solution 
Maybe a security issue?

Hello leppie!
Doesn't really comfort me
Anyway, thank you for replying.

hello,
does anyone know a way to access all the Forms that are available in an application at design-time in Visual Studio? I need to get access even to Forms that are currently not opened in Visual Studio, getting the class names of these forms would be enough, then I could instantiate them by myself.
Thank you

Have you tried to click on a project, then go to the project menu at top of screen and select Show all files. This will display all files currently inside that project, even those that have not yet been added to visual studio.

thanks for the help....but I want to get all the forms programmatically at design-time...I need this for a custom control I develop.

Hi all,
iam developing a project in C#.net 2.0.
Here i need to connect to the HP9000 database and open two connections one after the other. Till here i have done it well. After opening two seperate connections in two seperate windows i should be able work independently. But by the time i open the second connection it is closing the first one and returning the results of program run using second connection.
I need to use asynchronous programming here............
Can any one help me out................

Anyone know if it is possible to have multiple bootstrappers on one installer, currently I have one for the .net framework to check if installed, if not it must be installed fisrt, now I want to add one for the msde, any ideas??
Thanx in advance

I have created a class library and want to pass value into a unction that is inside the class library.its public and static type. i want to pass the value from the main windows application i created after this class library.

is there concept of handles in C#, if yes can u please tell me links of articles on handles or can u atleast give me an idea of how it works.
thanks

There are handles in the Windows.Forms namespace but they are used primarily for COM/Interop where they have to communicate with Win32 APIs etc.

How I will convert the 20 to 0010 0000 format and I want retrieve the third bit (in this case 1)
from 0010 0000
|
|
|
|
|
I use this to retrieve a bit:
public bool GetBit(int bitOrder)
{
return Convert.ToBoolean(errorNumber & (0x1 << bitOrder));
}
|
|
|
|
|
What is errorNumber and bitOrder
|
|
|
|
|
Ooo.. sorry, I didn't change the variable name of my code.
int number = 20;
int bitOrder = 2;
bool bit = Convert.ToBoolean(number & (0x1 << bitOrder));
// 00010100 -> Bit 2 is true, bit 3 is false
// 76543210
Console.WriteLine(bit.ToString());
|
|
|
|
|
That's a nice code. By using that u can make ur own function
Like...
public bool GetBit(int No,int bitPos)
{
return Convert.ToBoolean(No & (0x1 << bitPos));
}
But be carefull (MSB->LSB) BitPos = 0 = LSB

I wanted to draw the lines with higher precision for one of my project. So instead of using point structure, I thought to make a use of pointF strucuture. I made one sample application to test how precision differs in case I use pointF strucutre then point. Following is the sample code which i written to draw a lines on my form :
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint (e);
e.Graphics.DrawLine(new Pen(System.Drawing.Color.Red),new PointF(20.0F, 100.0F), new PointF(100.0F, 100.0F));
e.Graphics.DrawLine(new Pen(System.Drawing.Color.Green),new PointF(20.0F, 100.51F), new PointF(40.0F, 100.51F));
}
As per above code, I tried to draw 2 lines with very minimal difference in y co ordinates. I was shocked to find out that pointF rounds the co ordinate value while drawing the line. As per above example, if I keep Y co ordinates for 2nd line between 100.00 to 100.50, I can see only one line drawn as lines are drawn with the same co ordinates. But if I keep the Y co ordinates for 2nd line even 100.51 then I can see two seperates lines. This means pointF strucutre rounded the y co ordinate value to 101 and that is why i could see two different line. I tried to check the things by increasing and decreasing the resolution of my screen but it didn't help. If such is the behaviour then there is no difference between the point and pointf and we can not get the better precision then 1 pixel while plotting a drawing.
Can any one pls explain me above behaviour? I want to draw the lines with higher resolution so can anyone give me the idea of how to achieve it? I hope I'm clear with my question and expectation?

It is impossible to get higher resolution than 1 pixel. That's the smallest point the hardware can draw, regardless of what the software asks for. The impact of rounding will vary (appear to take effect) differently on screens with a different pixel density (dpi), but pixel density can't be changed without changing the hardware.

Graham,
Thanks for your reply.
Rob Graham wrote: It is impossible to get higher resolution than 1 pixel
If we can not get resolution higher than 1 pixel then what is the need of having two seperates structures i.e. point and pointF. Merely passing the values in float doesn't make sense if internally it is going to get rounded off.

If you for an example use a transform that scales the graphics by 1000%, you can make use of the higher precision. The rounding will take place after the scaling but before the actual drawing, so if you specify a rectangle with the size 0.53 x 0.78, it will draw a rectangle with the size 5 x 8 pixels.
Have you tried to change the InterpolationMode and SmoothingMode of the Graphics object? That might change how the coordinates are rounded.
