Um, no. This is pretty much the crux of your problem. You need to provide the complete text of the exception for anyone to be able to help you?

Hi,
I am encountering problems with clearing the combobox, the first value gets automatically selected. Even though i have set the SelectedIndex to -1 in the load event.
Another problem: I have placed the combobox on a tabpage of a tabcontrol. If I clear the combobox and then swtich tabs the first value again gets automatically selected.
The combobox is bound to string array.
Using .NET v1
It seems like a .NET bug to me. Any help would be appreciated.
Thanks.

If you haven't already created one, add an event handler to the combobox for SelectedIndexChanged. Then add some dummy code at the beginning of that method and place a break point on the dummy code. Then, when the index changes, the break point will be hit and you can track where it was called from.
Hope that helps.

I am failing in finding a way to use the new ListView.OwnerDraw=true and render a custom background.
- ListView.BackgroundImage does not work for our needs.
- SetStyle(ControlStyles.UserPaint, true); causes OnPaint and OnPaintBackground to fire *after* OnDrawItem, erasing any custom Item rendering.
Am I missing a way to custom draw a ListView background while using the new-fangled OwnerDraw?

Q. Unable to get a Profile custom (object) collection to bind to GridView,etc (IList objects)?
This is my first custom object so I may be doing something rather simple, wrong, or it may be something else to do with the Profile object. Either way, I need help 
Here's a brief description of the code----------------------------------------------------------------------------------
1) I have a custom object: "School.Teachers" (see below)
2) which is used as a Profile object data type in the web.config file:
<profile defaultProvider="AspNetSqlProfileProvider" >
<properties>
<add name="Teachers"
type="School.Teachers"
allowAnonymous="true"/>
</properties>
</profile>
3) I'm setting the value of a Profile object (ASP.NET 2.0) equal to the custom object:
School.Teachers tlTeachers = new School.Teachers();
tlTeachers.Add(new School.Teacher("Buck"));
Profile.Teachers = tlTeachers;
4) Code like this works:
Label1.Text = Profile.Teachers.Count.ToString(); // The number of items in the profile object
Label1.Text = Profile.Teachers[1].FirstName.ToString(); // The value of an item at a particular index position
5) But this does not:
GridView1.DataSource = Profile["Teachers"]; // Populate the GridView1 from the Profile Object
GridView1.DataBind();
The custom object: "School.Teachers"---------------------------------------------
[Serializable()]
public class Teachers : CollectionBase
{
public Teachers()
{}
public Teacher this[int index]
{
set
{
List[index] = value;
}
get
{
return (Teacher)List[index];
}
}
public int Add(Teacher value)
{
return List.Add(value);
}
public int IndexOf(Teacher value)
{
return List.IndexOf(value);
}
public void Insert(int index, Teacher value)
{
List.Insert(index, value);
}
public void Remove(Teacher value)
{
List.Remove(value);
}
public bool Contains(Teacher value)
{
return List.Contains(value);
}
}

Hello,
I have textbox.text = row["TotalArea"].ToString();
In VS 2003, all the trailing zeros were removed, so if the value of the area was 60.0000, then I would see only the value of 60.
However, in VS 2005 the same statement gives 60.0000. Exact value from a server. How can I make sure for all values the zeros are removed.
Thank you.

Specify the format string you want to use in the .ToString() method.
TextBox.Text = row["TotalArea"].ToString("###.##");

But that way if the value has 3 decimal values, it will cut it short.
So I guess what I am asking, how come the same command produces different results in both version of Visual Studio?
|
|
|
|

Actually, I'm not getting the results your describing. No matter what I input for a datatype, I'm always getting the trailing zero's removed when .ToString() returns.
You might want to try to force the value to a known type first before calling ToString() on it:
textbox.text = ((float)row["TotalArea"]).ToString();

Is there some documentation of all available formatting rules? In my opinion MSDN lacks this information, but maybe I'm just blind

Do you mean this[^]?
Be sure to look at the index on the left side of the page to see additional information. Formatting is a MUCH larger topic than it would appear to be.

How can I make a form ALWAYS topmost regardless if another form within the project has been set to topmost? Thanks in advance.

try adding to your database at your forum-msgs table another field called "Type", you should probably use numbers for this.
when you call for your messages at your page, try putting first the ones with type = 1, and later get the others.
this is a prioraty for your messages, then you can arrange them.

Ummm....And this has what to do with making a form TopMost???

hmmm... escuse me for being new here and not knowing **** about anything...
but now i get what he sais... sorry 
|
|
|
|
|
So, is there a way to do this?
Thanks

well... i think that the best solution is that when you show it, you use the command form.showdialog() insted of form.show, this way it won't enable it to go to the last one...
that's the best option that i could think of, i don't think that you can do topmost with some other and not enable it to switch forms... unless...
you can do an event "On leave", and then do a focus command on the form, that way if you leave, it will get focused on the form and wouldn't be able to switch... i think that that would work.
no moer options for me...
good-luck, NaNg

Hey, no offense. We just found it really odd that the OP kind of asked a question about, say, washing a dog, and you gave him instructions on aging cheese.
We thought you posted a reply to a question, but clicked on the wrong Reply link. That's how far off topic you were!

Well, off the top of my head, you have a problem. Your app can only have one TopMost form. The one that gets set to TopMost LAST stays there. Ther previous ones get knocked down the z-order. It looks like you're going to have to manage your TopMost property a bit more carefully, and sparingly.

Hey guys.
I'm writing a program that is integrated with Outlook 2003. When I create mails from my program, i'm having trouble inserting the default signature the "right" way. The signatures are stored locally in different formats, but I cannot seem to access them by the Outlook SDK object model.
Anyone out there who have encountered, and solved this issue?
Regards, Thomas.
