Here is the modified code for the function that calls func1(getList()) and other functions from the dll:
void listTheMembers(unsigned __int16 ID1, unsigned __int16 ID2)
{
unsigned __int16* arg3;
int i;
unsigned int test;
printf("\nMembers in list %d on server %d:\n", ID2, ID1);
if((test = getList(ID1, ID2, &arg3)) != 0)
{
printf("Error getting member list for %d: %d\n", ID2, test);
return;
}
if(!arg3[0]) {
printf("No members\n\n");
freeTheAllocatedMemory(arg3);
return;
}
for(i=0; arg3[i]; i++)
{
char* nameOfMember;
if((test = getName(ID1, arg3[i], Member_Username, &nameOfMember)) != 0)
{
printf("There was an error in querying member's username: %d\n", test);
break;
}
printf("%u - %s \n", arg3[i], nameOfMember));
freeTheAllocatedMemory(nameOfMember);
}
printf("\n");
freeTheAllocatedMemory(arg3);
}
The signatures for the called functions are:
unsigned int getList(unsigned __int16 ID1, unsigned __int16 ID2, unsigned __int16** result);
unsigned int freeTheAllocatedMemory(void* ptr);
unsigned int getName(unsigned __int16 ID1, unsigned __int16 MemberID, size_t flag, int* MemberName);
No. Some articles yes. And I am in the middle of writing my own.
That's great, it will be awesome to read one.

seeing the real function name, and example code using it, I now know the native function is allocating an array and setting its pointer through arg3 (which you later must free again). So you don't need any fixed nor GCHandle and this code of yours[^] should be pretty close. However your int [] managedArray = new int[1] is still wrong, they are 16-bit numbers, so use short!
Check again in the way I indicated here[^].
When in doubt, compare results for a native caller and your managed caller.

I am receiving following values in the index 0 of the array, and index 1 is always 0:
504150240
504150256
504150272
504150288
504150880
504150896
504150912
504150928
504150944
504150960
It looks like address values.

That most probably isn't hex as I see 9 digits (for a 16-bit number???); it takes hex to get maximum probability of seeing a pattern if there is one.

This is the actual value and its hex equivalent for the 0th index of the array. I printed these values in a file like this:
System.IO.File.AppendAllText("c:\\projectLog.txt", Array[0].ToString());
System.IO.File.AppendAllText("c:\\projectLog.txt", ":");
System.IO.File.AppendAllText("c:\\projectLog.txt", Array[0].ToString("X8"));
System.IO.File.AppendAllText("c:\\projectLog.txt", Environment.NewLine);

505140544:1E1BD540

Here is to elaborate (remember I initialized the array[1000] with values 0 to 999):
Index 0: 486734960 : 1D02FC70 , Index 1: 0 : 00000000 , Index 2: 2 : 00000002

Index 0: 486735008 : 1D02FCA0 , Index 1: 0 : 00000000 , Index 2: 2 : 00000002
Index 0: 486735024 : 1D02FCB0 , Index 1: 0 : 00000000 , Index 2: 2 : 00000002

OK, these clearly are pointers, they are multiples of 16, and ascending.
And your C code needs to pass one of them to get a member name.
You still have lots of details wrong, e.g. pointers cannot be int16, yet you declare arg3 as int16 pointer.
FYI: I retire from this thread; it has taken you till now to not tell what it is about, to provide real function names, and to mostly ignore what I have replied before.
You still have a lot to learn, I suggest you read a couple of books first.

That is not my code, it is part of a propriety SDK that I received to work with. And I am under obligations not to release the code (might get fired ). And that SDK has the int16 implementation.
I retire from this thread
I am sorry to hear that.
it has taken you till now to not tell what it is about, to provide real function names
Well you now know why.
mostly ignore what I have replied before
That's not true I have used almost all of your suggestions, and learned a lot in the process.
You still have a lot to learn, I suggest you read a couple of books first.
That is very true, that is why I was asking you about the particular book (If you have any suggestions in this regard it will be helpful). Thank you very much for all the time and efforts you have put on this. I appreciate it a lot.

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 )
{
}
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.

Thanks Mr
I did not ask to suspend
But asked for help
If you can not help me I would not Alngliq of no benefit
I did not ask for assistance only after the test, Mr.
Thanks

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.

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!

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;
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.
