I guess you need a web control in your form, which can paint direct to your ad page, or to urls provided by the webservice.

How can I set a public value of a parent form from a child form?
|
|
|
|

It's easy!
You can pass your parent form to child form, and then you can do what you want.

Don't make it public. Use delegates to create communication between forms. You can pass form instances around, but it's ugly, and hacky. Delegates are the right way to do this. There's a CP article on passing data between forms which covers this nicely.

you must declare the parent property (Property Procedure) as static in the parent form then u can set it from any child form.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
in the child form just by accessing the parent property like this
ParentFormName.StaticProperty = anyValue;

You can iterate over the drives available and see if one is removable. The DriveInfo class in the System.IO namespace is, from memory, what you need.

hi all.
I was wondering if anyone can assist me..
I have this code below:
DataTable dtSource = m_dtUsed;
DataTable dtDest = dtSource.Clone();
foreach (DataRow dr in dtSource.Rows)
{
DataRow drNew = dtDest.NewRow();
// this code work perfectly
object[] obj = new object[dr.ItemArray.Length];
dr.ItemArray.CopyTo(obj, 0);
drNew.ItemArray = obj;
dtDest.Rows.Add(drNew);
// why this code can't work?
// after dr.ItemArray.CopyTo(drNew.ItemArray, 0), i find drNew.ItemArray is still empty,i don't know why?
//drNew.ItemArray = new object[dr.ItemArray.Length];
//dr.ItemArray.CopyTo(drNew.ItemArray, 0);
//dtDest.Rows.Add(drNew);
}
Any help would be appreciated.

What does 'not working' mean ? What does it do instead ? What does MSDN say ?

Thanks Christian Graus for your reply.
The issue is :
After "CopyTo" operation, the destination array(here is drNew.ItemArray) is still empty.

dr.(obj, 0);
That won't even compile.

The ItemArray property returns a new object array that contains references to the data in the data row. You are copying the data to this array, and then you are throwing it away. Replacing the references in the object array doesn't change the data in the data row.
Despite everything, the person most likely to be fooling you next is yourself.

Thanks Guffa for your help.
I think my incorrect code copied confused you.
The fact is like this:
1)This code can work and the drNew.ItemArray have my wanted data.
------------
object[] obj = new object[dr.ItemArray.Length];
dr.ItemArray.CopyTo(obj, 0);
drNew.ItemArray = obj;
2)But the method below seems bad.
------------
drNew.ItemArray = new object[dr.ItemArray.Length];
dr.ItemArray.CopyTo(drNew.ItemArray, 0);
dtDest.Rows.Add(drNew);
i found drNew.ItemArray is still empty.I don't known why?

I already explained why: The ItemArray property creates a new array. Changing anything in that array doesn't change anything in the DataRow. So, you create a new array, fill it with data, and throw it away.
Despite everything, the person most likely to be fooling you next is yourself.

I'm trying to disconnect socket connection and then want to reuse again when any new client request comes but as I Press disconnect and Re-login then get following Error Message
SocketException was unhandled.
Message:"A blocking operation was interrupted by a call to WSACancelBlockingCall"
ErrorCode:10004
Please help me out how to close socket properly so user re-login again successfully.
Regards,
Shanzay

It would be hard to guess the exact cause without looking at the code. However the WSACancelBlockinCall exception generally happens when you stop listening as Listen is a blocking method.
Call the Close method to close the connection.

Hi,
I want to get byte[] from MultiPage TIFF image.
Have tried out lots of things but not getting solution.
Please suggest me.
Image final; <br />
final = GetMultipageTiffImage();<br />
ImageConverter converter = new ImageConverter();<br />
Byte[] imageByteArray = (byte[])converter.ConvertTo(final, typeof(byte[])); this line is having error. as tiff image is multiple page file.
If doing with below code then also getting same error
byte[] blob;<br />
MemoryStream ms = new MemoryStream();<br />
Image image = GetImage();
image.Save(ms,System.Drawing.Imaging.ImageFormat.Tiff);
blob = ms.ToArray();
Thanks,
Sun Rays

how to adding numbers from multiple textboxes?
|
|
|
|
|
You can't add the numbers as long as they are in the form of strings. You have to convert them to numerical data before you add them.
There are plenty of methods to parse numerical data, like Int32.Parse, Int32.TryParse, Convert.ToInt32, and similar for most numerical data types.
Despite everything, the person most likely to be fooling you next is yourself.

Try NumericUpDown instead.

Could someone clarify a question i have about the code snippet shown below, i know when the useing block ends the OleDbConnection's Dispose method is called, but what i'm not clear on, is the OleDbDataAdapter's Dispose method called also as it is inside the using statement or must I Call it my self? Any information wuold be appreciated.
using (OleDbConnection connection = new OleDbConnection(_connectString))
{
OleDbDataAdapter adapter = new OleDbDataAdapter();
adapter.SelectCommand = new OleDbCommand(_selectCmdText, connection);
// additional processing
}
