VS.NET comes with a handy install creation wizard, you can create setup and deployment package using that. It has options to pull in the runtime on demand,it can also take output from other projects on the solution.

No it doesn't. The CLR merge module it has is only to satisfy dependencies with .NET Framework assemblies. This is clearly outlined in the .NET Framework SDK docs / MSDN. To do this, you need to write a bootstrapper (executable) that checks the necessary registry key and installs the framework before continuing the Windows Installer portion of your application (something I happen to know a lot about and follow closely).
Wise for Windows Installer (www.wisesolutions.com) did it right: the bootstrapper should also see if Windows Installer 2.0 is installed (the MSI runtime). Since it is required for .NET and the .NET installation requires Windows Installer 2.0 (makes sense, right?), your bootstrapper can merely check to see if .NET is installed. If it isn't, you need to install it anyway, which includes the Windows Installer 2.0. If MSI 2.0 is installed but not .NET, no harm done.
If you look in the framework SDK docs (in the TOC), there is a lengthy topic on deploying .NET with your application. The MSM that is meant only to satisfy dependencies (which is why it is marked as Ignore by default) and only includes assemblies - it does not include the CLR, Fusion, or anything else required for .NET to actually run!

Thanks for the clarification, I had thought the installer would take care of installing the runtime along with the application. I guess .Net or not installation is always going to be a pain. I will go through the docs. thanks again.
Cheers,

I would like to know, if it is possible,or should I say feasible to have remoted window form..in the event I am being ambiguous I will explain..
Can I remote a Window form class so that a client can just connect to the remoted object and activate it, and run it on client side..so that virtually no code for that form is available on client side..other than perhaps an class interface for the remoted forms..I am sure with enough MarshalByRef or Serialization attributes, it is possible, but was not sure if it was possible?
Thanks for your time guys/gals

How do I make the form show spaces for a string that has spaces following the last character? For example: "ABCDE ". The label never shows the spaces after it. Thanks.

you wont see the space, because it's just a space , but you can check if there's a space at the end of the label very easily , eg:
VbCode:
<font color="blue">private</font> <font color="blue">void</font> button2_Click(<font color="blue">object</font> sender, System.EventArgs e) <br> { <br> label1.Text="sometext "; <br> } <br> <br> <font color="blue">private</font> <font color="blue">void</font> label1_Click(<font color="blue">object</font> sender, System.EventArgs e) <br> { <br> <font color="#0000FF">if</font>(label1.Text.EndsWith(" ")) <br> { <br> MessageBox.Show("found a space!"); <br> } <br> } <br>
Vb:
<font color="blue">Public Function</font> TwinsOnWay(<font color="blue">ByVal</font> twins <font color="blue">As String</font>) <font color="blue">As String <br> Select Case</font> twins<br> <font color="blue">Case</font> "Gender" <br> <font color="blue">Return</font> "Two Girls" <br> <font color="blue">End Select <br> End Function</font> <br>

I am trying to send a document (text/plain) to a server (.aspx page). I am always having a time-out (if I specify GET, I get a 404, as I expected).
When I look in the IIS log, I see the following:
2003-07-02 20:17:03 127.0.0.1 - 127.0.0.1 80 POST /Test/WebForm1.aspx - 500 87 -
This appears in the log whether or not the page exists on the server.
The 87 error means "The parameter is incorrect". I suspect that it has something to do with the Content-Length. Here is a code snippet I use to fill the HTTP stream with the document:
protected virtual void FillHttpStream(IDictionary pRequestParams, HttpWebRequest httpRequest)
{
string httpRequestDocument = (string)pRequestParams["RequestString"];
StreamWriter httpStreamWriter;
if ((httpRequestDocument == null) || (httpRequestDocument == String.Empty))
{
throw new Exception("No document to send");
}
httpRequest.Method = "POST";
httpRequest.ContentLength = httpRequestDocument.Length;
httpStreamWriter = new StreamWriter(httpRequest.GetRequestStream());
httpStreamWriter.Write(httpRequestDocument);
}
I should at least receive the 500 error code, but I time-out.
I could also use a tutorial on programmatically send a document via the HTTP POST method, if anyone know of any.

HI All,
I am trying to authenticate my username password using Advapi32.dll with function LogonUser. I am passing my Username and Password and domain and all things which need to pass in this function. But I am always getting false from this function. I am using windows 2000 Prof. and i have installed microsoft visual studio .net 2002 on my system.
One strainge thing is this exe is running on XP box very nicely. So any body tell me what could be the problem?
thanks,

Hi,
Actully I'm facing the same problem you've got! I think the domain paramter must take the name of the PC the file is in, not the name of domain or DC. This has nothing to do with Server! it's about connecting to a file in a PC, I thinks this is it!!
If you found the solution for that please send me it:

Hoang Dung, the following is not the best code on the globe but hope it gives you some ideas.
// construct table for Tasks grid and define columns
m_dtTasks = new DataTable("Tasks");
m_dtTasks.Columns.Add("Task Name", typeof(string));
m_dtTasks.Columns.Add("Frame Maker Location", typeof(string));
m_dtTasks.Columns.Add("Approved", typeof(string));
m_dtTasks.Columns.Add("Approval Cycle", typeof(string));
OleDbCommand cmd = new OleDbCommand(sSelectQuery, conn); // have yr query & connection ready
OleDbDataReader reader = cmd.ExecuteReader(); // DataReader is now loaded with data
while(reader.Read())
{
nNumRowsAffected++;
Console.WriteLine("TaskName = " + reader.GetString(0));
sTaskName = reader.GetString(0); // TaskName
sFrameMakerLoc = reader.GetString(3); // FrameMakerLocation
sApproved = (reader.GetBoolean(11) ? "Y" : "N"); // Status
sApprovalCycle = reader.GetString(12); // Approval_Cycle
// construct a new data row
drTask = dtTasks.NewRow();
drTask["Task Name"] = sTaskName;
drTask["Frame Maker Location"] = sFrameMakerLoc;
drTask["Approved"] = sApproved;
drTask["Approval Cycle"] = sApprovalCycle;
// add new row to table
dtTasks.Rows.Add(drTask);
}
dgdTask.DataSource = dtTasks; // attach data source to grid
Hope it helps

Class A
{
public event MyEventHandler DataChanged(A myClassA);
....
}
Class B:A
{
...
//Raising the DataChanged event in this child class leads to error saying
//DataChanged can only be on lefthand side of += or -=
DataChanged(this);
}
The problem I am encountering right now is my inability to raise the
DataChanged event within the child class (leads me to believe event
inheritance is not present in c# yet?). I remember reading VB.NET is
capable of event inheritance though.
Is there a nice work around to problem?
Thanks .

Normally how things are done is:
<font color="#008800">
public delegate void MyEventHandler(object sender, EventArgs e);
<font color="#008800">
Class A
{
<font color="#008800">
public event MyEventHandler DataChanged;
<font color="#008800">
protected void OnDataChanged(EventArgs e)
{
if(ElementMouseUp !=null)
ElementMouseUp(this, e);
}
....

Hello,
I want to add Items (string-Variables) to a Combobox.
But running the application, a NullReferenceException is thrown.
"The Object is not set to an instance of an object" (something like this, I've the german SDK, sorry)
I fill the Combobox in the constructor of an selfmade Dialog:
public dlg_clickedOrtAuswahl(string[] liste, int anzahl)
{
for (int i = 0; i < anzahl; i++)
{
//filling the Combobox cb_Auswahl
this.cb_Auswahl.Items.add (liste[i]);
}
InitializeComponent();
}
What could be wrong?
I've tried it with a HashTable, but the same error accours, binding the hashtable to the combobox with cb_Auswahl.DataSource = myHashtable.
Thanks a lot, for your help.
Greetings
Torsch

The combobox is created in the InitializeComponent method, so you can't use it until after that method has been called.
Also, I assume anzahl is the length of the array; you could also use liste.Length.

That there is no such thing as a "BitmapButton" class in .NET? Something that displays a bitmap but acts like a button--up, down, mouse over, has focus, ALT-[x] functionality?
Please, someone tell me I'm wrong.
(And don't point me to Button's Image member, because it doesn't work when using a manifest--no bitmap appears--and it the ImageAlign property does work right--bottom is top, and vice versa, left is right, and center doesn't).

And MouseDown, MouseUp, GotFocus, LostFocus, and I'm working on MouseEnter/MouseLeave, which doesn't seem to be working. I smell a short article. I can't believe there isn't a BitmapButton control on CP (I've looked, only thing I found was something using code valid only in one of the beta's).

It makes your GUI's look pretty. Like Microsoft's. Rounded buttons, etc. I guess if you have different skins, it adjusts your GUI to whatever skin the user has configured. Look at the first screenshot in http://www.codeproject.com/csharp/AAL-5A.asp[^]. Notice the radio button too. However, also notive that the tab pages have white tabs and grey backgrounds for their body. They can't even get that right.
