C#

Thanks a lot!!! Jerzy:)

hmmm,thanks:):rose: Mazy "So,so you think you can tell, Heaven from Hell, Blue skies from pain,... How I wish,how I wish you were here." Wish You Were Here-Pink Floyd-1975

I think it's not bad to take a look at "managed C++" part, I think your answer is there. Mazy "So,so you think you can tell, Heaven from Hell, Blue skies from pain,... How I wish,how I wish you were here." Wish You Were Here-Pink Floyd-1975

override the MouseDown Event from the ListBox Control: private void listBox_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) { if(e.Button != MouseButtons.Right) return; int nIndex = listBox.IndexFromPoint(new Point(e.X,e.Y)); if(nIndex != -1) listBox.SetSelected(nIndex,true); } Rgrds Martin

for any conversation i use System.Convert. Example: string str = "555"; int i = System.Convert.ToInt32(str); (also you can use ToInt16(), ToInt64() ...) See System.Convert for additional Information. Rgrds Martin

If its too messy its probably a good idea :) Personally I find myself redoing lots of code because it becomes difficult to discern what is going on. Domenic [CPUA 0x1337] wrote: So, does this sound like a good plan? I just iterate through the rows every time columnchanging is called, determine the valid ones, rebuild my data structure using those, and then rebuild my datagrid from my datastructure. Without knowing whats going on its hard to say what would be best. From what I know I would let the datatable do its job then pull the data out of it only when its needed. Handling the ColumnChanging/ColumnChanged events as needed for validation; then run a final validation with the RowChanging event to ensure that fields within a row are ok. Domenic [CPUA 0x1337] wrote: And how to decide between ColumnChanged and ColumnChanging? Here's a quote from the documentation. The ColumnChanging, RowChanging, and RowDeleting events are raised during the update process. You can use these events to validate data or perform other types of processing. Because the updates are in process during these events, you can cancel the update by throwing an exception, which prevents the change from being completed. For more information, see Data Validation in Datasets. The ColumnChanged, RowChanged, and RowDeleted events are notification events that are raised when the update has been completed successfully. These events are useful when you want to take further action based on a successful update. Hopefully you can get some idea where to go from here :) James Sonork ID: 100.11138 - Hasaki "Smile your little smile, take some tea with me awhile. And every day we'll turn another page.

Okay, now I understand. Depending on the operating system, you still have to write different code. Thank you very much for your remarks! Kind Regards, Ludwig

try to get code from this book. chapter 13 - Programming C#. by Jesse Liberty Link for source code is in this web site. www.libertyassociates.com

This should give you a base to start from. using System; using System.Windows.Forms; namespace Namespace { public class MyButton : Button { public MyButton() : base() { SetStyle( ControlStyles.AllPaintingInWmPaint | ControlStyles.UserPaint, true ); } protected override void OnPaint(PaintEventArgs e) { // Draw the button } } } HTH, James Sonork ID: 100.11138 - Hasaki "Smile your little smile, take some tea with me awhile.

Hehe lets hope so. It also seems that .NET server has it already and will have it. On my beta it has 'The .NET Framework' however I have not dabbled in that realm as of yet. .NET or not .NET? MFC is the question......

:-D thank you!! now i get the messages.
