Hello,
I create controls dynamical by the values of the rows in my BindingSource. I do this in the event CurrentChanged.
I add a control to a panel and bind this control to the BindingSource.
the problem is: the current changes BEFORE I add the fitting control.
that means a wrong (old) control might still exist when the BindingSource changes to another row. so the content might not fit for this control. the "old" is cleared and the new (fitting) one is added afterwards.
how could I clear the old control BEFORE the "current Changed"?
thank you!

instead of binding it in current change event... bind it item databound of that table

Hello,
thank you for your answer! The problem is, i dont find this event. I can imagine such a event in .net 1.1 webcontrol-datagrid.
I am using .NET 2 on Winforms.
can you specify your answer? thank you.
thank you

I noticed something weird with the DataGridView.Columns. I set up a DataGridView on my form and I wanted to set a DataTable as the DataSource. When I did this all of my columns are displayed, but I only wanted to have some of them displayed. With a DataGrid I would just use the DataGridTableStyle object, but they don't work with DataGridView. So instead I set at design time all the columns I want to see displayed and map them to the column names in the DataTable using DataPropertyName of each column. This works, in that the data from the table get displayed in the right columns, but the DataGridView rather unhelpfully decides to fill in all the missing columns too. So I add all the missing columns at design time but set them to be not visible. Now this seems to work fine.
Next I decided I'd like to be able to toggle the visibility of some of the columns. So I set up some menu options and try to toggle the visibility using the Column object I set up at design time. Some like this:
colMyColumn.Visible = !colMyColumn.Visible;
This works fine before I bind my DataTable, but not afterwards. After binding colMyColumn is no longer a member of the DataGridView's Column collection. I.e.
MyDataGridView.Columns.Contains(colMyColumn);
Returns false. However, this:
MyDataGridView.Columns["colMyColumn"];
Returns the correct column that is a member of the column collection. My question is why does colMyColumn no longer hold a reference to the same object as the one in the column collection? Why has the DataGridView appear to have cloned it when it bound to the DataTable? What is going on here?
Thanks

I've got a large number of values to output as text, so I want to change the behavior for my entire outwput mehtod rather than calling Double.ToString(...) every single time. THe problem is that despite intelisense claiming that the numberformat Property is both a getter and a setter, when I try and change it I can an invalidArgumentException that the instance is readonly.
<br />
System.Globalization.NumberFormatInfo normal, changed;<br />
changed = new System.Globalization.NumberFormatInfo();<br />
changed.NumberDecimalDigits = 6;<br />
System.Threading.Thread.CurrentThread.CurrentCulture.NumberFormat = changed;
|
|
|
|
|
by using a System.Globalization.CultureInfo object i can avoid a crash, but the default conversion of a double to a string completely ignores the value. nor do either of the following work:
string s = someDouble.ToString(changed.NumberFormat)<br />
string s = someDouble.ToString(changed)<br />
|

CultureInfo's properties are read-only once assigned to your app's thread. You'll need to create a new CultureInfo object with the settings you desire.
System.Globalization.CultureInfo info;<br />
info = System.Globalization.CultureInfo.CurrentCulture;<br />
info = new System.Globalization.CultureInfo(info.LCID, true);<br />
info.NumberFormat.NumberDecimalDigits = 6;<br />
System.Threading.Thread.CurrentThread.CurrentCulture = info;
Unfortunately, the Double.ToString() method (without arguments) ignores the NumberDecimalDigits property. You have to do a Double.ToString("N") for it to work, which is not what you want.
Unless of course there's a way to change the default format string for a double.

Is there a SQLDMO equivalent for Oracle? I am stuck in my project due to this. I have developed an application that uses SQLDMO that works great for SQL Server database. Now I need to extend that app to Oracle and am having a hard time finding a tool that does to Oracle what SQLDMO can do for SQL Server.
Thanks in advance.

I could be wrong but I don't think there is an exact equivalent of SQLDMO in Oracle. You should go to Oracle's developer's network and query their message boards or knowledge bases. Oracle does have some .NET tools such as ODP.NET.

Hi all,
I want to serialize Cursor object on server
and deserialize it on client.
I tried to implement it but i got
exception "Cursors can't be serialized"
Can anybody give me a code snippet that
shows how to do it?
thanx

A mouse cursor? There's really nothing to serialize, except maybe which cursor is being used and it's position on the screen. What are you trying to do with this?

I want to inform client that which cursor is being used.
Can u give me idea how to do it.

Why??? There's no reason for it! The cursor changes depending on what's going on in the current application, what window and what part of a window the cursor is over, ... I just don't see any useful information in it.
This is basic serialization to an XML file.
Dim serializer As New XmlSerializer(GetType(Cursor))
' You can use other stream types, but you never said what you're doing with this
' or how your passing this to any client...
Dim writer As New StreamWriter(filename)
serializer.Serialize(writer, Cursor.Current)
writer.Close()

I have created 3D head and my appliction that I input text it will read . I want to programm lips movments accourding to out put soud. My text to speech application have programmed using C#. Help me !

Of course, there's no way to do this using the .NET framework class library as it's just not a common programming operation. You're going to need some software that hooks up sounds with vertices on your 3d model; this is certainly something you don't want to be forced to program yourself (which would be an enormous undertaking, I would imagine).
Search the web for 3d lip syncing, you should get some hits. There is software out there built for doing this.
Now, if you don't need high-quality, full fidelity lip movements, you could just write some animation into your 3d model to move its mouth while the text is being read...

I only started coding c# a week ago, and I’m a little stuck! I'm making an application where the user has 1 second to click the mouse button once they see movement on the screen.
My problem is: what is the best way of waiting until the mouse button has been pressed without hogging the system resources? If I use a sleep then the onclick method for the mouse click won’t be called until the sleep has finished I assume?
I need the time at which the mouse button was pressed, therefore sleeping for 1 second and then seeing if the mouse was pressed isn't good enough. Currently the application was coded by someone else, and it uses a while loop until the time equals 1 second later. Obviously this allows the application to receive messages and make the onclick method call occur but it also uses all the processing resources.
Further to this, is there a way of getting a time stamp of when a message occurred? This would be more accurate than getting the time once the on click method has been called.
Any help with this would be greatly appreciated!

If I've understood you correctly, then I suggest you something like this:
remember when timer was started in absolute values.
use another thread loop with Join(interval) method, where interval = precision of time measurements, that you need. You can use timer component in the form to implement this simply. On each timer tick - check, is it second already.
onClick event must first remember what time is now, in absolute values, stop timer, then calculate difference between start and stop time.
Should work.

Thanks Robin, I was thinking of something like that, I just wasn't sure if there was something similar to the sleep method which allowed messages to pass. I'll have a go at implementing it that way.
Many thanks

Put a timer on the form that fires after a second. Then you just have to sit back and wait for events, and see if the click or tick fires first.
