Hi,

most, if not all, event handlers get as a first argument "object sender" which will
hold the Control that fired, so if all your P_Click delegates are connected to PictureBoxes,
just cast sender to PictureBox and you know which one got clicked...

Uhmm... But how can i tell which image fired up the event? I am using the same picture box to draw the images in the form... would be comparing the image from the picture box with the array of images i have???

If not would you mind writting a simple example of how to do it please?

Thanks!

I do not agree. You have a while loop in which you do P=new PictureBox(),
so yes the variable P is used over and over, but it is a new PictureBox on every iteration
of the loop.

object sender can be cast to PictureBox, it will point to the one PictureBox that you clicked,
and if you get it's Image property, you have a reference to the Image you clicked.

So you don't need a separate collection to get this working properly.

You are completely right about this, i just said it wrong. I meant it how could id the picturebox if i was using the same variable all the time...

I think i do know now how to do it .... thanks a lot... I wouldn't have done it without you!

Importing Extreamly Large Files

Hello,

I am using C#.net to create a win app. I need to import extreamly large files into a SQL server database? I was wondering what is the best way to go about it. I have used SqlBulkCopy althought it is fast it times out before the import is complete due to the size of the file. I am also in the process of trying a split import with SqlBulkCopy (If I have a file that is 10 records I would import the first 5 and then import the next 5). Am I on the right track?

Any suggestions would be great.

Thanks

DateTime Compare Problem

13-Nov-07 11:12

I have sql query in C#

SELECT Last_Date
FROM MYTABLE
WHERE Last_Date > CONVERT(DATETIME, '13.11.2007 22:43:50', 103)

Note: Last_Date column data type is datetime

Example; If my Last_Date column like this
13.11.2007 22:43:49
13.11.2007 22:43:50
13.11.2007 22:43:51

So this query return this values
13.11.2007 22:43:50
13.11.2007 22:43:51

If I change ">" operator to ">=" operator, result is same. How can I eleminate "13.11.2007 22:43:50" value? I want to get greater than (">") values.

Thanks..

There is a micro second component, I believe. Try 22:43:50.999

Yes, its true. I know but how can I solve my problem. I think this is related about style code "103". But I don't know which style code is correct my problem. I search but I can't find.

First of all what u need to do AFAIK is to split the datetime into three parts lik date,time and am/pm. then put the checking.this will fetch u the xact result.

Hi,
In a dataGridView, I can Load data from single table of DB and save back the changes to DB using SqlDataAdapter,DataTable,SqlCommandBuilder (for auto generate of Insert,Update,Delete statements).
Now this don't work on View (Join and nested query), that data gets from multi Tables.
How can I do this to this operation done on Multi Tables?

Best wishes

Wouldn't a neat and cool stored procedure that handles the Insert/Update/Deletes be more cool, elegant and robust, since you particularly mentioned about multi tables?

How to create a full-fledged Browser and additional custom tool bar?

Hello everyone,

I have a WebBrowser control in my Windows Application. If I am not mistaken the WebBrowser control is just the parsing engine of the browser.

I would like to transform the WebBrowser control into a full-fledged browser like Microsoft® Internet Explorer, and like to add a custom tool bar with new feateures (buttons) for the custom built tool bar. If I am not mistaken that sould be done using Browser Helper Objects (BHO).

I was wondering if anyone canbe kind enough to point me to the right direction for this project.

Thank you very much and have a great day.

No, it's also a full-fledged renderer and controller.

Most barcode scanners act just like a keyboard and will send the data scanned directly to the control that has the focus without any programming. If yours is different, consult the manufacturer's documentation.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
