James,
In the case that you haven't checked email in a bit, I sent you some information concerning the application that might help in diagnosing the problem.
Thank you again for all your help.

James,
I didn't hear back from you yesterday after sending the code. Hope all is well.
If you get a chance to look the code I sent today I made a change in it that you'll need to know about.
See below:
The change deals with the pointer to the actual realtionship name instead of the table ID:
From: oRPT.DataSource = oDrv.CreateChildView("ItemID");
To: oRPT.DataSource = oDrv.CreateChildView("HSCTI1");
Unfortunately, I still do not get the child view.
<br />
<small><br />
public void Customers1_ItemDataBound(Object sender, RepeaterItemEventArgs e) <br />
{<br />
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem)) <br />
{<br />
Repeater oRPT = (Repeater)e.Item.FindControl("Customer2");<br />
DataRowView oDrv = (System.Data.DataRowView)(e.Item.DataItem);<br />
oRPT.DataSource = oDrv.CreateChildView("HSCTI1");<br />
oRPT.DataBind();<br />
}<br />
}<br />
<br />
public void Customers2_ItemDataBound(Object sender, RepeaterItemEventArgs e)<br />
{<br />
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem)) <br />
{<br />
Repeater oRPT = (Repeater)e.Item.FindControl("Customer3");<br />
DataRowView oDrv = (System.Data.DataRowView)(e.Item.DataItem);<br />
oRPT.DataSource = oDrv.CreateChildView("CTPT1");<br />
oRPT.DataBind();<br />
}<br />
}<br />
</small><br />
Please let me know if you have any suggestions.
Sincerely,
Tim

Well, i'm quite new to C#, but i wanna learn. So, i've decided to make a program, but i have some dificulties in finding a label that can be set to transparent(only the label, through a transparency key).
The idea is that i have a large picture in the form and that i want to put some labels(or buttons or anything else which has some writing in front and the option to click on it... and, of course can be set to transparent) on the picture so that when you click it, it shows a messagebox.
The basic idea is that i need an object that can stay on top of a picture and be transparent.
p.s.: the idea with cutting the the picture in small sizes which can be set as background won't work because there are many labels... 
thank u!

Only forms can have an opacity key but you can set the label to get its color from an ARGB (Alpha Red Green Blue) value.

C# newbie has a simple C# question here:
suppose I have a list in PhotoManager.cs class under /App_Code. In photos.aspx.cs I want to call one item from the list data such as string skname, what should I do? I know if you use dataset you will have something like this: dsCategory.Tables(0).Rows(0).Item("skname") but I don't know how to do it with List. I googled for a while still no luck. BTW, the GetCategory method returns single row of data.
public static List<getcat> GetCategory(){
.....................................
GetCat temp = new GetCat(
(int)reader["skid"],
(string)reader["skname"]);
list.Add(temp);
................
}
I am thinking something like this
string strTemp = PhotoManager.GetCategory.Item("skname")
Obviously this has syntax error. any input is appreciated. thanks a lot in advance!

I have created my own user control by subclassing UserControl. In the layout of the user control is a standard Button. The Button has its own Click event. How to I programatically raise the Click event of the UserControl when the Button inside is clicked?
Thanks,
Mark

Inside the UserControl:
private void button1_Click(object sender, EventArgs e)
{
this.onclick(e);
}

Hi
There is a Usercontrol which is displayed in the modeless state.
Now i display another Usercontrol on top of the the other control and the other control is now completely invisible (it goes behind the new one i have shown now).
The invisible control has a a button control in it and it has a mnemonic set so that upon a particular key press, it will fire its Click event code.
Now when the user is currently working with the new Usercontrol that is displayed on top on the old one (which is currently invisible, but it is there), and hits a key, say "J", the old control's button control's click event gets fired. This is because the key "J" is its mnemonic. How to ensure that when that Usercontrol is not visible, the key down hit is not consumed by the hidden usercontrol's button control. and is used by the one on top - i.e. the new control.
I hav tried all sorts - OnVisibleChanged(), OnLostFocus() etc where i tried to remove hte Click event handler from teh button's click event and adding it when the control becomes visible, etc, but these do not work.
I think the only way to do that is to do something in hidden control's WndProc().
Any ideas?

Hello,
I have a vb code which l am trying to convert to c# and having many problems with it. PFD = rpt.DataDefinition.ParameterFields.Item("@dt"). In c# there is not a parameterFields method called Item. So i am not sure how do l get the name of my parameter that is in the crystal report viewer.
Can anyone help me convert this code to c#.
<br />
Imports CrystalDecisions.Shared<br />
Imports CrystalDecisions.CrystalReports.Engine<br />
<br />
Dim mDate As DataTime = #01/01/2005#<br />
Dim rpt As New CrystalReport1<br />
Dim PFD As ParameterFieldDefinition<br />
Dim PValues As ParameterValues<br />
Dim Parm As ParameterDiscreteValue<br />
<br />
PValues = New ParameterValues<br />
<br />
PFD = rpt.DataDefinition.ParameterFields.Item("@dt")<br />
Parm = New ParameterDiscreteValue<br />
Parm.Value = mDate<br />
PValues.Add(Parm)<br />
PFD.ApplyCurrentValues(PValues)<br />
<br />
CrystalReportViewer1.ReportSource = rpt<br />
Thanks in advance,
Steve

try this:
<br />
using CrystalDecisions.Shared;<br />
using CrystalDecisions.CrystalReports.Engine;<br />
<br />
DateTime mDate = DateTime.Parse("01/01/2005");<br />
CrystalReport1 rpt = new CrystalReport1();<br />
ParameterFieldDefinition PFD; <br />
ParameterValues PValues = new ParameterValues();<br />
ParameterDiscreteValue Parm;<br />
<br />
<br />
PFD = rpt.DataDefinition.ParameterFields["@dt"];<br />
Parm = new ParameterDiscreteValue();<br />
Parm.Value = mDate;<br />
PValues.Add(Parm);<br />
PFD.ApplyCurrentValues(PValues);<br />
<br />
CrystalReportViewer1.ReportSource = rpt;<br />
hope it works

Thanks for all your help.
PFD = rpt.DataDefinition.ParameterFields["dt"];
Have to take out the @ sign of an error message says field name does not exist.
Thanks,

Hello everybody .
I am developing chat / Server Application and my project worked will on my localhost and Lan but not on Wan or the internet. I posted this problem at the past and some professional programmers helped me i thank them very very much really i appreciate that from them , I Found that the windows xp has built in firewall i enabled it to access internet users to my server ports manually from my network connection properties. Ok and it works and i chatted with my friends through the internet using my application , But the problem is i need anyone install my messenger on his pc to enable these ports automatically during installation not to make the user manually enable his/her firewall . I know it must have a possible way to do that through win32 send messages function . Is there anyone knows how to send message programmatically to the firewall of windows to enable these ports through code through calling sendmessage , And if there any other methods i appreciate that from you all

If you think about it, a firewall that allows programmatic access to its setup woul be pretty daft! Virus writers could quite easily circumvent the protection of the majority of computer users.
I think the possibility of doing this (at least without local admin rights) is slim to nil.

Hi coders !
I need to binary convert a byte (unsigned 8 bit, 0 to 255) to an
sbyte (signed 8 bit, -128 to 127).
I have no problem converting an array of bytes to any other
type using BitConverter.To[type] functions, but there's no
BitConverter.ToSByte ....
VS 2003 - compact framework SP3
any ideas ?
Ciao
Marco

You can just convert it, ignoring overflow, as there is no data loss.
byte source = -42;<br />
sbyte dest;<br />
<br />
unsafe { dest = (sbyte)source; }
---
b { font-weight: normal; }
|
|
|
|
|
Are you sure ?
First off
<br />
byte source = -42;<br />
is indeed wrong since byte is UNSIGNED (0 to 255).
Second a simple cast doesn't convert BINARY the values,
meaning a 10010011 is (let's say) 215 for a byte and
-81 for a sbyte.
still looknig for help
Ciao

Just a typo. Of course a byte can't be -42.
It was unchecked (as leppie suggested) that I was going for, not unsafe.
However, some testing reveals that you can just cast the value from byte to sbyte. You don't need unchecked mode for casting between signed and unsigned data types.
byte source = 214;<br />
sbyte dest;<br />
dest = (sbyte)source;
Now dest will contain the value -42.

What do you mean by convert BINARY, then?
---
b { font-weight: normal; }

It works perfectly, I did the same test
and got the same result.
By binary I meant exaclty that : having a brunch of bits read
from the sbyte point of view (so to speak)
Thanks a LOT everyone !!!
Ciao

ps: I WANT to install vs 2005 .... it's GREAT, but I have only

Try to use Convert.ToSByte(source);
May be this will work.
byte source =42;
sbyte dest;
dest = convert.ToSByte(source);

Hello all,
I have an application that performs alot of logging, as a result of this the execution time is increase by an unnacceptable amount. Unfortunatly the logging is a necessarily evil and the volume cannot be reduced
To get around this problem I placed the logging code into a typical threadpool implementation
delegate void ThreadedLogger(int logLevel, string data, Datetime logDate);
...
...
ThreadedLogger tl = new ThreadedLogger(LogWriter);
timl.BeginInvoke(1,
"log data",
Datetime.Now,
null,
null);
...
...
void LogWriter(int logLevel, string data, Datetime logDate);
{
}
Now this all works fine, and my execution times have dramatically dropped. The problem is that if the calling application exits before the the ThreadPool has finished the remaining items in the threadstack are purge and the log is never written.
Putting a wait in the code to ensure that threadpool has finished defeats the point of threading off in the first place, so i am looking for another solution. Does anybody have any ideas on possible solutions to this problem.

I created a class library and would like in one class to keep a variable of type
System.Windows.Forms.TextBox
However for some reason in the class library the namespace System.Windows is not known. Is this normal? Did I screw up a setting somewhere?
Please help me if you know what might be wrong...
Friendly Regards,
Davy
