First they need to help themselves. If people follow the posting guidlines and don't just come here asking stoopid question because they can't, or won't, do a little research firast then they can expect to be scorned.
On the other hand, if someone actually tries something, I am more than willing to help. Unfortunately there are less and less chances to do that due to the dross appearing in the forum.
If OP had stated they had tried SourceForge and could not find the older versions, I would probably have helped. However, when a ten second 'google - click - click' reveals the answer, I don't think I'm being too harsh about someone's lazyness.

I understand where you come from mate, please don't get me wrong, but there are nicer ways of doing things. The name-calling is a bit excessive I would say. But hey, people will eventuallyt learn to use google.........Someday...........I hope...........

Problem is, these cantthinkuses[tm] keep coming back and it starts to get boring:
Q: How do I ...?
A: Try Google.
Q: Gimme codz!
A: No!
Q: Why no work?
A: Where is your code example.
It works this way:
int stress = 0;
while (forum.HasUnreadThreads)
{
Message msg = forum.NextUnreadThread();
if (msg.Stoopid)
{
stress++;
if (stress >= 10)
msg.Answer("*&^%*&$*((% %^%^$&");
else
msg.Answer("Try google");
}
else
{
stress = stress / 2;
msg.Answer(Knowledge.Search(msg.Question));
}
}

With these clowns it's more like Light a man a fire and you keep him warm for the night. Light a man on fire and you keep him warm for the rest of his life.

Hi again,
I have another WPF problem.
A StackPanel contains a ListView
<stackpanel>
<listview name="theList" itemssource="{Binding ContactItems}"> ......
The ListView contains items called ContactItems. This ContactItems can be expand if the user want to edit it.
In edit mode this ContactItems is expanded (the selected ContactItems height is increasing). When the edit is finished I get a white space in the buttom of the list. It looks like the StackPanel has grown when I edit the contactItem.
Example (but the list is vertical..)
Before edit: "X X X X X X"
After edit: "X X X X X X "
Question:
Can I remove the white space without setting OnPropertyChange("ContactItems"), which will repaint the list. The problem is that it takes some time to update the list with OnPropertyChange("ContactItems").
Regards
Magnus

Try using yourListView.UpdateLayout(). It would be difficult to diagnose the actual issue with the information you have provided. Can you share the DataTemplate/Style you are using for the ListView.
Also, it's better you use the WPF forum[^] for WPF related questions.

Hi All. I have a wroking application that writes records to and Excel Sheet. I have now been asked by the users to make a small change to the program. After all records has been written to the Sheet I do a Calculation of All values in Two columns and write those totals to "D1" and "D2". I have been asked to write the totals to the bottom of the Sheet rather. Now, the current code I have that does this is as follows:
int lastUsedRow = objSheet.Cells.SpecialCells
(Excel.XlCellType.xlCellTypeLastCell, Type.Missing).Row;
int lastUsedColumn = objSheet.Cells.SpecialCells
(Excel.XlCellType.xlCellTypeLastCell,Type.Missing).Column;
objRange = objSheet.get_Range(lastUsedRow + 1,
System.Reflection.Missing.Value);
objRange.Value2 = "Total of Level 1";
objRange.Font.Bold = true;
objRange.Font.Italic = true;
objRange.Font.ColorIndex = "5";
When I try and change it to write the totals to the lastUsedRow + 1 it gives me an HRESULT exception. Here the code where it falls over on. I must add that when I debug it seems to be picking up the correct row, i.e. lastUsedRow + 1 but it fails when going onto the next Line of code. Any Ideas as to why this might be happening??
objRange = objSheet.get_Range(lastUsedRow + 1,
System.Reflection.Missing.Value);
objRange.Value2 = "Total of Level 1";
objRange.Font.Bold = true;
objRange.Font.Italic = true;
objRange.Font.ColorIndex = "5";

Just a thought, b/c I have not written XL macros for 15yrs, can you trust the specialcells to return the correct row/col. Is there a way of testing the value that you are trying to use. In my day there were no such things as specialcells so I kept track of where I was on the sheet manually.

My app make cross-thread calls to many main form controls. I have disable CheckForIllegalCrossThreadCalls by set it to false, without using any Invoke method for the cross-thread control update. And the app is running fine so far.
My question is: Is it okay to turn off CheckForIllegalCrossThreadCalls, for this cross-thread control update? What are the negative effects?
Thanks.

It is only for debugging and will only work when the debugger is attached. Here is what MSDN says,
Note that illegal cross-thread calls will always raise an exception when an application is started outside the debugger.

Not at all.
Your app will not work reliably if you do.
That property should never have been introduced, they created it when .NET (evolving from 1.1 to 2.0) got strict on cross-thread checking, so they thought it was wise to provide a way to continue doing things the wrong way.

hi all,
does any one know how to find a com port is default or not in C#?

hi,
how do find out what's your 'default com port' in general (e.g. in windows)? Is there anything I don't know? 
bye

Hi,
AFAIK there isn't a "default COM port" at the Windows level.
What may exist is a default port for some app, say a terminal server.
But then the notion only exists within that app, and how it gets selected is depending on that app.

Hi,
I am developing a contact book using C# WPF and a textbox can contain contacts as the user has added from the existing contact book. The textbox showing the selected contacts will looks like: "John; Peter; Tom;".
The user can add new names to the textbox but if he want to edit an existing name that name shall be highlight and not be able to edit the existing name, just like Microsoft Outlook when you send a new email and try to modify a email address added from contact list.
How do I adjust my textbox so it get this behavior?
Example:
The user has added the following contacts to the textbox. "John; Peter; Tom;"
The problem is how do I prohibit the user to modify contact "John" like "John123456789; Peter; Tom;"
If he starts modify contact John the textbox shall contains "123456789; Peter; Tom;" instead.
Regards
Magnus

I'm not sure of any WPF relevance but I would namage the position of the caret in the text (little flashing verticle bar) and depenting on the position and the relationship to the word and ; in the text manage the selected property of the text.

Hello,
Currently I am working on creating a drawing editor.
I am unable to find the function which can draw an arc using a mouse like a line by using the RevesibleLine function.
Thanks in Advance.
MR. Bats

I don't think there is one, there's only a method for drawing beziers, which means your user needs to define the individual points. To draw and have a steady arc come out, requires code to create a custom path, I beleive.
