Hello Friends..
I am using a datagridview which have a checkbox column.there is a delete button on the form.i want that when i click the delete button and none of the check box is checked(true). it will simply display a message that "Firrst select a row".
|
|
|
|
|
Loop through each row in the datagridview and check for the ones where the value of the cell with the checkbox == true. If there are none then be rude to the user and ask him/her to check 1 or more item.

suppose there are 20 rows and one is checked and i put the code (checkbox=true)with in the loop then 19 times it display "Please Select a Row". and i think its not good.
|
|
|
|
|
Thinking is not one of your strong suits is it.
Loop the data rows
count the checked items
ask for confirmation to delete n# items checked
OR call the user an idiot and ask them to check 1 or more item.
If you can't work these things out you are really going to struggle as a developer!

I've only ever done this once but IIRC you put the notifyicon into the tray, when closing the app you need to remove it before closing the app. Use the mainform.onclosing event to remove the icon.

correct, unless your app crashes or you abort a debug run. Then the icon stays put.

yes it is.
1. create a web service application
2. in a method from your web service call your stored procedure using System.Data.DbCommand inheritance (i.e SqlCommand for SqlServer) by set it's CommandText property with name of your stored procedure, CommandType = CommandType.StoredProcedure and create it's related parameters (see SqlParameter class as sample)
3. Create a windows application (windows form or console)
4. Add Web reference from your web service address to your windows application, usually it will create a class refer to your web service object
5. call the method in step 2 from created web service class in your windows application
hope it helps

What makes you think there is any pressure on Dhiam, he is doing you a favour by trying to help you. No pressure on him!.
This is pretty straight forward design and construct for a developer, why is there pressure on you to perform this if you are a newbie. Asking someone for a "low level implementation" is the same as asking for the codz, greatly frowned upon in these forums. You need to do the work yourself, including the research into how to build a web service.

Sorry for the pressure.
If it's urgent, pay to get it done. Try rentacoder[^] or work at it and figure it out.
The pressure is only on you, no one here will code for you.

Hello
I am about to write an application which will be responsible to transfer files between two servers. Can someone suggest me the best possible way to do that? Should I go for socket programming? or dot net remoting? or web-services?
I am open for suggestions or comments.

I have two coordinates on the screen x1 and y1 and i have an object at that location.. now i have x2 and y2 which will be the destination point of my object.. I am planning to move my object 1 pixel at a time following the path from x1, y1 to x2, y2.. is there a formula that you can recommend?
|
|
|
|
|
Just work out the ratio of x2 - x1 to y2 - y1, and that will tell you the ratio of pixels to move in x versus y.
If you want reasonably smooth movement you'll need to track positions in floats.
If you want very smooth movement you'll need to take the time per update frame into account.
There are three kinds of people in the world - those who can count and those who can't...

yeah i was asking for the ratio formula
