Make a backup of it all (for safety) and just rename the folders. When you open the solution VS should complain that it can't find the projects, and give you the option to locate them.

Hi,
Can anyone tell me if I can use .Net Framework 2.0 with Visual studio .Net 2002. I have not been able to add references of the system.dll of version 2.05. The message I get is something like not recognized COM or dll.
If can please explain how to use debug using 2.0v with VS .Net 2002.
Thanks
Vijay

You cannot do this. Visual studio is tightly coupled to the framework. VS02 will work with .net1.0 only. Try the free Express versions or sharpdevelop if you don't want to buy VS05.

I am trying to communicate over Rs232 using a basic RS232 class for .NET. I am able to communicate fine for the most part with most devices. However, a few devices don't respond or respond with garbage when I try to receive data from them in my program. If I connect with HyperTerminal and send the same commands, I get a correct response, and if I try to connect with my application after having connected with HyperTerminal, my application talks fine with the devices.
It is almost as though HyperTerminal is doing some additional initialization that a straight serial connection isn't. Is there anything that anyone can think of that I could do to get my application to behave more similarly to the HyperTerminal way other than checking the settings such as baud rate, parity, stop bits and flow control?
I know this is sort of open ended, but there isn't really another way to describe it so far as I can tell.
Thanks for any feedback.

Hyperterminal doesn't do any extra initialisation so it something to do with your code I'm guessing. Check settings and encodings again 
Sorry but in my experience if Hyperterminal does something and your program does something else then its almost guaranteed that it's not Hyperterminal. (I know there are faults but in my experience these only occur when you try something stupid / abnormal).

What terminal protocol are you using? Perhaps that has something. HyperTerm auto-negotiates the protocol by default when it connects.

I have .Net 1.0.3705
When Setting TrustLevel for Remoting Application for Server as well as for the client, by following command,
Dim SProvider As IServerChannelSinkProvider
Dim CProvider As IClientChannelSinkProvider
SProvider = New BinaryServerFormatterSinkProvider()
CProvider = New BinaryClientFormatterSinkProvider()
CType(SProvider, BinaryServerFormatterSinkProvider).TypeFilterLevel = TypeFilterLevel.Full
chan = New TcpChannel(props, CProvider, SProvider)
I get an an error in the second last line. And when i comment it run run the serverand the client i get an error
like this:
<<""This remoting proxy has no channel sink
which means either the server has no registered server channels that are listening, or this application has no suitable client channel to talk to the server."">>
I have also read that all the remote application has Trustlevel =low ByDefault.
Help me out!!!

Hi
I using XmlValidatingReader to validate xml against xml schema.
My xml is looking like this:
<some_name>
... some integer and string data
<xmlData>
... random xml data, like : <a>asdsds</a><b>dsds</b>
</xmlData>
</some_name>
I have no problem with integer and string data, but I don't know to which type to set xmlData element.
xmlData can contain random xml which structure unknown.
Any suggestions?

Hi,
OK - I've searched CP and Google (in that order...) and found next to nothing, so now I turn to the lounge for help. If this should be in the C# or .net framework forum, please say so and I will move it. The specific error at hand might suggest so, but I believe that the general question is, well, .. more general ?
Scenario:
My software (.Net 2.0 app) running on a client win2000 pc.
Problem:
After some time I get the mentioned error dialog from the framework. I think it is some sort of a failfast ? Anyway, I can't figure out from where the error originates and press the "What data does this error report contain?" link and get a new dialog box with this:
Error signature -------------------------------------------------------
EventType: clr20r3 P1: program.exe P2:1.83.2270.18759
P3: 441e74ff P4: system.windows.forms P5: 2.0.0.0 P6: 4333aefa
P7: 16b3 P8: 159 P9: system.componentmodel.win32
Reporting details -------------------------------------------------------
Bla bla bla...
"View the contents of the error report" link
"Read our Data Collection Policy" link [Close]
Pressing the "contents" link gives me yet another dialog box with this interesting information
Exception Information
Code: 0xe0434f4d Flags: 0x00000001
Record: 0x0000000000000000 Address: 0x000000007c59bc3f
General questions:
Since this is a debug compilation of the program, I would have expected the more informational "old" framework 1.1 error message with the call stack etc, that could tell me where things died. I don't know how to decipher the "error signature" above, as I can't find any official specification of WHAT the parameters P1 -> P9 actually contains. All that google gives from Microsoft is a load of "what has been fixed in <insert_ms_app_here>". Grr....
1)
What does the parameters mean ? Is there a specification somewhere ?
2)
Why don't I get the "old" 1.1 style error dialog with the stack trace. Can I do something to get that ?
Sigh... I moved to 2.0 to get better tracing and so, but it might turn out to be a bit less helpfull when something stops working. Any comments and links will be most welcome !

Dear all,
I am doing a project which is loading the data from a DataSet into an in memory object Excel worksheet, then setting up the PrintTitleRows for the Excel worksheet, finally redirecting the in memory Excel worksheet to the client side.
When I run it, the error message is "System.Runtime.InteropServices.COMException (0x800A03EC): Unable to set the PrintTitleRows property of the PageSetup class at System.RuntimeType."
The following is my code, anyone can help me with it is highly appreciated.
Dim excelCol As New excelColumn
Public Structure excelColumn
Public data() As String
End Structure
Dim dt As New DataSet 'DataSet is filled in another fuction
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim iRow As Integer
Dim iCol As Integer
Dim myTable As DataTable
Dim filename As String
excelCol.data = New String(4) {}
excelCol.data(1) = "A"
excelCol.data(2) = "B"
excelCol.data(3) = "C"
Dim qxl As New Excel.Application
Dim qxlwb As Excel.Workbook
Dim qxlws, qxlwstemp As Excel.Worksheet
qxlwb = qxl.Workbooks.Add()
qxl.Visible = True
qxlws = DirectCast(qxlwb.Worksheets.Add, Excel.Worksheet)
qxlws.Name = "All Columns"
Try
For iRow = 0 To dt.Tables(0).Rows.Count - 1
For iCol = 0 To dt.Tables(0).Columns.Count - 1
If (iRow = 0) Then
qxlws.Range((excelCol.data(iCol + 1)) & CStr(iRow + 1)).Value = dt.Tables(0).Columns(iCol).ColumnName
End If
If (Not ((dt.Tables(0).Rows(iRow).Item(iCol)) Is DBNull.Value)) Then
qxlws.Range((excelCol.data(iCol + 1)) & CStr(iRow + 2)).Value = DirectCast(CStr(dt.Tables(0).Rows(iRow).Item(iCol)), String)
End If
If ((dt.Tables(0).Rows(iRow).Item(iCol)) Is DBNull.Value) Then
qxlws.Range((excelCol.data(iCol + 1)) & CStr(iRow + 2)).Value = ""
End If
Next iCol
Next iRow
qxlws.PageSetup.PrintTitleRows = "$1:$2"
'Me.Label1.Text = qxlws.Range((excelCol.data(2)) & CStr(9)).Value
Response.ContentType = "application/vnd.ms-excel"
Response.Write(qxlwb)
qxlws = Nothing
qxlwb = Nothing
qxl = Nothing
Catch ex As Exception
Me.Label1.Text = ex.ToString
Finally
If Not (qxlws Is Nothing) Then
ReleaseComObject(qxlws)
qxlws = Nothing
End If
If Not (qxlwb Is Nothing) Then
ReleaseComObject(qxlwb)
qxlwb = Nothing
End If
If Not (qxl Is Nothing) Then
ReleaseComObject(qxl)
qxl = Nothing
End If
System.GC.Collect()
End Try
End Sub

I've started to use /clr in my old MFC app using VS 2005
How do I distribute my application in an easy way? It only works on computers having visual studio 2005.
I have run Dependency Walker an error is shown:
Error: The Side-by-Side configuration information in "MyApp.exe"contains errors. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem (14001)
I got the following error when I try to launch my app:
This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem
All I want is to make my application run on another computer before lunchtime...
I have the .NET Framework 2.0 (dotnetfx.exe) installed on my other cpu.

Hi guys...
As you can probably tell from my question i am new to programming c# & the .net framework.
My question is to ask if it is possible to create an application that will play music when a caller is put on hold?(using a smart device).
Any help is greatly appriciated.
Regards.

That would depend heavily on your phones ability to even do this, regardless of the code used. You might want to find out before wasting a bunch of time trying to code something that will never work.

You do not explicitely insert a page break. Just set the HasMorePages property of the PrintPageEventArgs to true and another PrintPage event will fire after the current one is finished.

Thanks Roberts i found the solution few minutes later in some other code project article.

I was wanted to share some performance observations after fiddling around with arrays and IList<type>. Since e.g. a double[] a array automatically implements IList<double> in .NET 2.0 I can conveniently accept IList<double> as argument for any method without also needing an overload for double[]. However, after some quick testing it seems a performance penalty is involved using the IList interface! I used this small program to compare the options:
using System;<br />
using System.Collections.Generic;<br />
using System.Text;<br />
<br />
namespace TestListVsArray {<br />
class Program {<br />
static void Main(string[] args) {<br />
double[] a = new double[10000];<br />
<br />
for (int i = 0; i < 3; i++) {<br />
TestA(a);<br />
TestB(a);<br />
TestC(a);<br />
TestD(a);<br />
Console.WriteLine();<br />
}<br />
}<br />
<br />
private static void TestA(IList<double> a) {<br />
DateTime start = DateTime.Now;<br />
double x = 0d;<br />
for (int j = 0; j < 1000; j++) {<br />
for (int i = 0; i < a.Count; i++) {<br />
x += a[i];<br />
}<br />
}<br />
Console.WriteLine("{0}, {1}", DateTime.Now - start, x);<br />
}<br />
<br />
private static void TestB(IList<double> a) {<br />
DateTime start = DateTime.Now;<br />
double x = 0d;<br />
int n = a.Count;<br />
for (int j = 0; j < 1000; j++) {<br />
for (int i = 0; i < n; i++) {<br />
x += a[i];<br />
}<br />
}<br />
Console.WriteLine("{0}, {1}", DateTime.Now - start, x);<br />
}<br />
<br />
private static void TestC(double[] a) {<br />
DateTime start = DateTime.Now;<br />
double x = 0d;<br />
for (int j = 0; j < 1000; j++) {<br />
for (int i = 0; i < a.Length; i++) {<br />
x += a[i];<br />
}<br />
}<br />
Console.WriteLine("{0}, {1}", DateTime.Now - start, x);<br />
}<br />
<br />
private static void TestD(double[] a) {<br />
DateTime start = DateTime.Now;<br />
double x = 0d;<br />
int n = a.Length;<br />
for (int j = 0; j < 1000; j++) {<br />
for (int i = 0; i < n; i++) {<br />
x += a[i];<br />
}<br />
}<br />
Console.WriteLine("{0}, {1}", DateTime.Now - start, x);<br />
}<br />
}<br />
}<br />
Output on my machine was (tests are repeated to rule out exceptional starting behaviour):
<br />
00:00:01.1015840, 0<br />
00:00:00.6008640, 0<br />
00:00:00.0801152, 0<br />
00:00:00.0801152, 0<br />
<br />
00:00:01.0915696, 0<br />
00:00:00.6008640, 0<br />
00:00:00.0801152, 0<br />
00:00:00.0801152, 0<br />
<br />
00:00:01.0815552, 0<br />
00:00:00.6108784, 0<br />
00:00:00.0801152, 0<br />
00:00:00.0801152, 0<br />
Concluding: iterating of the array interface is quite some faster than iterating over the IList interface of the same array object. Unfortunately using a.Count in the for loop also does cost some. I hoped the compiler/runtime was smart enough such that it would not cost anything.
Let's add those overloads again now.

Of course there will be a performance penalty for using a collection over an array. Even though with generics you can easily implement strongy typed collections (avoiding casting and boxing unboxing), the collections in fact use arrays. They provide you with more flexibility than an array (like you don't need to know the number of elements and they can grow as needed) but basically what it does is array operations.
There are some ways you can improve performance, if you know the number of items you can setup the MaximumLenght property of your collection.
Also, both with arrays and collections, whenever you try to access a member, the CLR will perform a bound check.
but if you access it in a for loop, where you expressely use the .Count, or .Lenght property, the compiler is smart enough to detect that and won't do bound checks with a considerable performance gain (in long running loops).
for example
suppose you have an array a and you want to iteract.
you can do it like this:
int limit = a.Lenght;
for (int i = 0; i < limit; i++)
{
}
this will do a bound check for each iteraction.
if you do
for (int i=0; i < a.Lenght; i++)
{
}
this boundcheck will not be performed.
