I have a DLL which may be called by more than one exe or more than one instance of an exe. I need the DLL to be able to figure out which exe it is or more precisely, I want it to access some config information regarding the exe.
I am currently trying to fool around with
System.AppDomain.CurrentDomain.SetupInformation (this is in my DLL to get info on the app)
but not sure if that is what I should be doing.
Any clues?
Thanks

Figured it out. I need to use System.Configuration and create an app config file to do what I need.

Can anyone tell me the correct code to use to clear the checkmarks (not the items) in a CheckedListBox? I want to do this as sort of a reset function to allow the user to start over making their selections.
Thanks for any help you can give me.

for( int i=0 ; i < checkedListBox1.Count; i++ ) <br />
{ <br />
checkedListBox1.SetItemChecked(i, false); <br />
}
Earlier I provided the solution for normal Checkbox.

You left out the refences to Items. But it works. Thanks.
It should be:
for (int i = 0 ; i < checkedListBox1.Items.Count; i++)
{
checkedListBox1.SetItemChecked(i, false);
}

I am creating a strongly-typed collection class for a custom class using the CollectionBase class. I have added a Sort() function to the class with the following description:
public void Sort()
{
myClass[] tempArray = new myClass[List.Count];
tempArray.Initialize();
List.CopyTo(tempArray, 0);
Array.Sort(tempArray);
List.Clear();
foreach(myClass val in tempArray)
List.Add(val);
}Is there a better way to do this, performance wise? Or is this implementation a decent one?
FYI: The list count for this collection will be very large when used in the application.

Maybe there is another way of doing it, but the only one that passes through my mind now is the SortedList container.
Do you really need to have a Sort method or can the list be sorted all the time? If this is the case, then deriving from or aggregating a SortedList can give you the best performance.

The collection cannot be automatically sorted. In use, the collection will usually be unsorted. Only on occasion will sorting be necessary. Thanks.

Since you're inheriting from CollectionBase you can use the underlying ArrayList's Sort method. That will (should anyway) in turn call the underlying Array's Sort method.
You can access the ArrayList by the protected InnerList property on the CollectionBase.

It actually calls an quicksort implementation. Saw it many moons back. Quite fast as well.
Hey leppie! Your "proof" seems brilliant and absurd at the same time. - Vikram Punathambekar 28 Apr '03

If the data is not already sorted (which is the worst case of the QuickSort algorithm)

hi,
i have a databound datagrid control in a winform. i need work arounds for some problems.
1. When i click the last row in the datagrid a new row is automatically added. i need to control this new row addition. Before adding a new row I need to check existing rows in the datagrid and validate against some criteria. Depending on the values existing in the datagrid I want to reject or accept the addition of the row. How can i do this. I tried onRowchanging event of the table the datagrid is bound to but got into some other problems.
2. How can i undo a latest edit made in a databound datagrid again based on some criteria.
3. I have included a combobox inside the datacolum and the combobox again includes a tree view inside. i got most of the job done but whenever i try to add a new row in the datagrid it adds up three new rows. Then when i click on the first of the newly added rows the other two disappear but when i click on the 2nd and 3rd i get the arrayindexoutofbounds exception. Any solutions for this?
hope I get some replies.
Thanks.

When I call StartService() Web Method of my Web Service, aspnet_wp.exe consumes around 100% cpu utilization. What is wrong with this?
[WebMethod]
public void StartService()
{
threadListener = new Thread(new ThreadStart(Listen));
threadListener.Start();
}
private void Listen()
{
//Some code for creating a init tcp listner
threadListener.Suspend();
}

Plz,
examine the memory consumption
using some tools. Tools such as System Monitor or Task Manager can isolate
those processes. When using System Monitor, if both the "Private Bytes"
counter and the ".NET # of Bytes in all Heaps" counter increase at the same
rate, this is evidence of managed memory consumption. Look at the size of
allocated managed memory and consider what the garbage collector is doing.
The allocation profiler might be helpful to you:

I want to make a browser likes IE, but .NET doesn't provide a web browser control ( I want something that I can configure it easily, not hard). Please help me.
|
|
|
|
|
The VS.NET Toolbox window can be customized to add ActiveX controls such as the web browser control. When you drop this control onto your form, interop libraries will be automatically built and used.
|
|
|
|
|
please tell me how to use that control( and what they are)!!!
|
|
|
|
|
Tutorial[^]. What this article does not say is that, instead of using the cmdline to extract what's known as interop libraries, you can let the VC#.NET IDE do it for you, by simply dragging the "Microsoft Web Browser control" COM component from the Toolbox to your Form.

I need to convert a string variable to an array of integers (An ASCII code for each character) and send it over to a Fortran code.
First, I have converted the string var. to an array of char (see below), but how can I convert this (kurt) to an array of integers?
string SetupPath;
char [] kurt;
int [] intFilePath;
.
.
.
kurt=SetupPath.ToCharArray();
intFilePath = ????

I create a Windows Service, I allow it to interact with the desktop and I can see the NotifyIcon in the try bar when the service start, but I can't use the Icon.
I explain better:
_I can see the icon
_I can see the tooltip
_I can see the baloon
_I can't see the Context menu when i click with the right mouse button
_I can't execute the action that I assign to the left mouse button.
So, the service can intercact with the desktop, but the user can't interact with the try Icon.
There is a solution?
Thanks for any help.
Regards,
Emanuele

The NotifyIcon only addresses the issue of the icon in the toolbar. In order for the user to interact with this icon, you have to create the context menu and click events for that menu.

I have create all.
If i run the app all run ok,
but if i do the same in a service there is that problem....
