Hello All,
I have recently developed a small application with C#.
What I wish to do is to add an uninstaller to the application that the user can use to uninstall my application instead of having to use the windows control panel.
Can someone please show me how to do this iin C#?
Thanks,
Maaran.

I am a newcomer to .Net Remoting. After I had read some articles at CodeProject,I did som work by my self.
I created three project:Server.exe,Client.exe,RemotableObject.dll.Here is my Client code:
<br />
using RemotableObject;<br />
...<br />
private MyRemotableObject remoteObject;<br />
...<br />
TcpChannel m_TcpChan = new TcpChannel();<br />
ChannelServices.RegisterChannel(m_TcpChan);<br />
<br />
RemotingConfiguration.RegisterWellKnownClientType(<br />
typeof(MyRemotableObject),"tcp://localhost:8080/MyRemotableObject");<br />
remoteObject = new MyRemotableObject();<br />
remoteObject.Method1();<br />
When I running the Client, it raise "System.IO.FileNotFoundException: File not found:RemotableObject".So I put RemotableObject.dll in the Client.exe's folder,and it's all well.
My question is: Does the RemotableObject.dll must be deployed together with every client? If it must,then what role does the RemotableObject.dll acts on the client? If it doesn't ,what additional work should I do to let RemotableObject.dll apart from the client?

Hi!
First you have to get a reference to the node you want to select and then you just have to call myTreeView.SelectedNode = theNodeReference;

thanks for ur reply
but then if u pass the node reference of a child node it is not accepting.... can u help me more plzzzzz
|
|
|
|

What do you mean by "it is not accepting"?
Either you have a reference to an existing node anywhere inside your tree, in which case the mechanism is working, or you don't have a reference to an existing node, in which case I'd expect the treeview to not select anything.
But without any code from your side it's impossible to tell what you did wrong.

Try something like this:
foreach (TreeNode node in myTree.Nodes)
{
if (node.Text == "12")
{
myTree.SelectedNode=node;
break;
}
}

hi sanjeev,
You can read the document first of all in a string, then find the number of occurences of <space> in the string.
sharma sanjeev wrote: And can i do formating
You will have to study the format of .doc file first to insert formatting in the file. When you know the format for, suppose italics, then you can insert that character in the right place.
You can also use Rich text box for formatting, if it supports .doc formatting (I am not sure abt the formats)
Hope this helps you.

How to validate a variable for numeric value.
Is any function is there to validat
|
|
|
|
|
Use Char.IsNumber(char c)
or parse it, for example Int32.Parse(string s);
if you get an exception, that means your
string is not a number.
|
|
|
|
|
int n;
if(int.TryParse(s, out n))
{
// n now contains your int
}
else
{
// was not a number.
}

Hi everybody!
I'm trying to serialize an object (PrintableListView that was posted on the site). to do that I created a class that will hold my object, and I marked it as [Serializable()].
The problem is that on the line:
bformatter.Serialize(stream, serial.plv);
when I'm trying to serialize the serial.plv (I marked plv as public), I get an exception, saying "Type 'PrintableListView.PrintableListView' in Assembly 'PrintableListView, Version=1.0.2088.26378, Culture=neutral, PublicKeyToken=null' is not marked as serializable." although I did marked the class as Serializable().
Does anyone have any Idea what could be wrong and how to fix it???
THANKS ALOT!!!

Hi,
PrintableListView is derived from ListView class. And the ListView class is not declared [Serializable()]. Thats why you cannot serialize the derived class PrintableListView objects.
If you want to save some data between the application runs then you can programmatically save the data to a text or binary file and read the data into the control when you start application next time.
Hope this helps !
