You can just include the merge modules in your setup kit and that would look after installing the required runtime dll's for your application. The link by kubben contains a link to get the merge modules.

You can make a Setup for your program by using Visual Studio. You can also use third party softwares like NSIS, InnoSetup and InstallShield etc.

Hi ,
I have written an assembly in C# which uses threads, and I want to add the reference of this assembly in both Windows Form and ASP.NET Web Form.
There is a method in a thread of my assembly which should send the current status of processing to Windows Form and Web Form .
My problem is, I first used the 'invoke and delegates' mechanism from my assembly to update WindowForm control , but this technique did't work on WebForm control as I could't find any equiavalent of 'Invoke' in WebForm .
Now I tried to use the Delegates and Events , I fire events from my assembly and try to catch those events in my WIndow Form , but getting error that "cross-thread operation is not valid" as I am trying to update GUI control frm my own thread....
Is there any way around to this ? I want to use technique through which I can update my both Win Form and Web Form controls !
Please I need help I m realy very badly struck here...
Thanks in advance.

I need to open a StreamWriter for a file, but have trouble mapping my Win32 CreateFile skills to C#, esp. the CreationDisposition. I need.
"Create file, truncate existing": That's probably what File.CreateText does
"Create File, error if it exist": ???
"Create File, Append if it exists": that's probably File.AppendText, but how di I figure out that it already did exist?
I can do the two latter ones by putting a File.Exists test in front of it - but that isn't the "atomic" operation.
Just Curious

If you create a FileStream first using then you can specify what you want to happen to the file.
FileStream fs = new FileStream(path, fileMode);
Where FileMode can be:
FileMode.CreateNew (exception thrown if already exists)
FileMode.Create (overwrites an existing file)
FileMode.Open (exception thrown if does not exist)
FileMode.OpenOrCreate (if exists then opens, otherwise creates)
FileMode.Truncate (opens existing file but wipes it, presumably throws exception if file doesn't exist)
FileMode.Append (appends to existing file)
Once you have opened it you can pass this to the StreamWriter's constructor.

Hi,
If a user edits a value on a DataGridView, the DataTable under its DataSource recognizes the change when calling DataTable.GetChanges()
However, if I edit a value programatically on the DataGridView, the DataTable.GetChanges() returns a NullReferenceException as if no change took place.
I know it saved to the DataTable, because I can look at it and see the updated value. Is there something else I need to call on the DataGridView after programatically updating it to make the changes noticable on the DataTable? Some type of commit method that is automatically called when a user edits?
Right now I am bypassing the error by updating directly on the DataTable, but I know the DataGridView.Rows is a much smaller collection to loop for changing than the DataTable.Rows (due to filtering already in place). Should I worry about this efficiency issue at all?
Thanks,
Pualee

The datagridview exists solely for the user's benefit. If you want to programatically modify a data set, modify it in memory - your DataTable directly. That is the correct approach.

Ok, thanks, I was worried I would never get answered

Can tell me anybody how can I populate a treeView from a class ... ?
|
|

You populate a TreeView by adding TreeNodes to its Nodes collection. See this[^] MSDN article.

I want to say that I have a class ... with many properties like primitive types or other types created by me.
I have an object populated with dates ... and I want to populate a treeview with dates from this object.

Can I create a class from a string name??
I want to Make a new instanc class from string name in C#.

Thanks For Your Time.

Yes we can using Reflection.
1. suppose you have added reference of a class 'clsTest' in your project.
2. then add
namespace System.Reflection
using System.Reflection;
now in your code write
Type tpClsTest = Type.GetType("clsTest");
object objTest = Activator.CreateInstance(tpClsTest);
now objTest represents the instance of your clsTest.

I am trying to write some some methods which will apply the System.Math methods to arrays instead of individual variables. I thought I might try a generic method (my attempt is below).
public static T[] Abs<T>(T[] array)
{
T[] absArray = array;
for (int i = 0; i < array.GetLength(0); i++)
{
absArray[i] = Math.Abs(absArray[i]);
}
return absArray;
}
The problem comes with the actual call the Math.Abs. The compiler complains:
Error 56 The best overloaded method match for 'System.Math.Abs(sbyte)' has some invalid arguments
Error 57 Argument '1': cannot convert from 'T' to 'sbyte'
Since the compiler doesn't know what type T is, I understand what is happening, but is there a way to make this work (or a better way to do this)?
I was just trying to keep from having to write several identical overloaded methods with differing types (and learn something in the process).

I don't think you can do it this way, T can be anything (int, float, bool, ...). You may have to write a function to get the type of the object and return the object as (int, float, sbyte,... )
