Getting the selected items from a radioButton group

Twyce28-Sep-09 6:42

I am trying to get the seleted radioButton from a group of radio buttons.
The program is supposed to check on the database for controls that match the selected radiobuttons. The radiobuttons are named High,Medium,Low.
For example

If a person selects High, the program must go through the database and choose all the controls that are rated High and then must load them into a listBox.

My problem is that the code i am using does not see the selected items and does not load the listBox.
I am usig SQL server database and stored procedures to do this.

Any suggestions on how i can go about doing this will be appreciated.

Not sure if you are doing this in a web page or in a rich client. In a rich client application it is very easy:

Create your group and put all radio buttons in there.
Bind all buttons to a single event handler.
In the event handler write something like this:
foreach ( RadioButton item in myGroup.Controls)
{
      if ( item.Checked )
      {
         // TODO: Insert your code here
      }
      else
          continue;
}

Now for the not-so-rich-and-pissy web interface you should confirm that all of your radio buttons have AutoPostBack=true and see if that helps your situation.

I suppose this would work better than trying to do it mentally, unless your Stephen Hawking.

Have you even tried searching for an answer or do you expect everyone else to do your work for you? This is something that just about any article on DataGridView should cover.

Take it easy there my friend..

Mark is simply saying you could have googled this, but just to get you started
the functionality you require is hidden away under :

DataGridView.Rows[rowindex].Selected = true;

On another note, people won't help you if your're rude.

dllnotfoundexception when compiling release version

tjeffries28-Sep-09 4:50

tjeffries

28-Sep-09 4:50

I have an application written in C# using VS 2005 that calls a C DLL.
Everything has been working fine until recently. A few days ago I sent a
release build to my client and they reported they are getting a
dllnotfoundexception. We worked through some similar issues some time ago and
up until recently the versions I sent out worked just fine.

Dependency walker tells me that WINMM.DLL calls MSVCR80.DLL, and there may
be a version problem. However, even if I put a version of MSVCR80.DLL in the
same directory, I still get the error. Apparently it is coming from the fact
that IESHIMS.DLL and WER.DLL are not on the system. I don't need ANYTHING in
those DLLs- all my DLL does is some mmsystem based wave playback. But that
does not alter the fact that Windows won't run the release version. The debug
version, by the way, runs fine, but only on a system with VS 2005 installed.

I have seen some references to the fact that the latest version of IE got
rid of IESHIMS.DLL and replaced it with something else. However, the
solutions I've seen posted don't seem to help. I'm running on XP (as is my
client) but this will be a commercial product, so we have to support Vista
and W7.

I have seen remarks dating from around 2005 that say certain manifests need
to be built certain ways to avoid this, but I have not figured out what is
involved. I would appreciate any thoughts on finding a solution to this!

Reflection-Typecasting on a SortedList / KeyValuePair

I would like to take any(unknown types) SortedList and get access to the KeyValuePair data as type object so I can then access the data.
Given
SortedList<string,int> tmp = new SortedList<string,int>();or
SortedList<int,myObj> tmp = new SortedList<int,MyObj>();or
......

I need to be able to do something like
foreach(KeyValuePair<object,object> kv in tmp).......

to get access to the objects then use reflection to determine type and such.

How can I typecast an object,which is of type SortedList to a SortedList.

public static string UnknownSortedListToStr(object tmp)
{
string res = "";
object n;
object v;

  // This Line Fails.(Unless the SortedList passed in(tmp) was declared <object,object>)
SortedList<object, object> si = (SortedList<object, object>)tmp;

if ((tmp.GetType().FullName.Contains("System.Collections.Generic.SortedList")) ||
(tmp.GetType().BaseType.FullName.Contains("System.Collections.Generic.SortedList")))
{
for (int i = 0; i < si.Count; i++)
{
string s = "";
n = si.Keys[i];
v = si.Values[i];
if (n != null)
s = n.ToString() + "=";
if (v != null)
s += v.ToString();
res += s + "\r\n";
}
}
else throw new Exception("Not a SortedList");
return res;
}

Take a look at this[^], particularly the last part of the answer from John Grove.

This[^], particularly Example 40, right near the end.

And finally this blog from Brad Abrahams[^].

One thing they all have in common is that they start with the Type of the collection, and get the parameter types from there. Once you have the types of the parameters, you can go practically anywhere.

You might find other useful/interesting stuff by googling something like reflection generic collections which is how I found the above.

I want to use dynamic background in my winform app, I used GIF image now, it looks not so good, can I use a flash as background? how?

In my opinon, I need to use "AxShockwaveFlash" to play the flash, this object is not under control of my app, so I can't draw on it...
