What do you mean the result is same? It happens in the same place? If so, maybe you could help us to help you by posting a relevant code snippet.

I ran into the same issue after upgrading to Windows 7 (and IIS7) A WCF service that was previously working started to get this error.
To fix, I went into the Build properties of my projects (Project/properties/Build Tab) and changed the Platform Targer to "x86". Then the problem was gone.

Hello everyone,
I have made some search, but can not find C# samples of using XmlDocument, either from MSDN or other sources.
Any recommended samples?
thanks in advance,
George

You didn't try very hard then. 5 seconds with Google threw up this[^].

Thanks pmarfleet!
I like this one. I add an additonal "sample" keyword to do the survey, and do not find as much as you did.

Can we have an string array and add strings elements to it at random points of time, without using a for loop??

You can not add element to array. Array has fixed lenght. You can only change any element in array any time:
myArray[0] = "hey bob!";
if you need to add element to array you need to create a new array(with more elements) and copy elements from old arrray to it together with you new elements. But this is pretty much what List<t> does, so if you need to add elements to array often at runtime I would recommend you to use List<t> which also has a method called ToArray which return current state of List<t> as regular array.

you can use arraylist for this purpose

No one uses the ArrayList anymore. The generic types in C# 2.0 have rendered it obsolete.
I suggest you check out the Generic List<>[^] type instead.

You can use generic List<string> class.

Good Morning all
i have recently moved from vb.net to C#, infact not moved but learning to use them both.i have been building N-Tier Applications with vb.net and there was a time when i have send a message from a BLL to the PL(Presentation Layer) in this case a Form, am building Windows Application. Now i have a BLL(Class) and i want to Display a messagebox, inn vb.net "Messagebox.Show" did not work, but instead i used "msgbox()" and it worked fine, now in C#, am looking for a Similar Function that will alow me to do that. I saw something like "mbox", but it seems it does do what i want.
Thanks

MessageBox.Show() works from a class too. Make sure you are using System.Windows.Forms namespace.

mbox is a code snippet. If you type in mbox and then press the tab (twice I think), it expands the text out into MessageBox.Show. Similarly, if you type prop and press the tab again, you get a property.

Hi i am developing an application in which i have required to get the print of panel control along with other control that are placed in panel control. I am able to take the print but there is a problem that i want that there should occur an Print Dialog befor printing but print Dialog does not occur so how can Print Dialog shows before printing...
CODE:
Global Declaration:
PrintDocument printDocument1 = new PrintDocument();<br />
System.Drawing.Bitmap memoryImage;
AT FORM LOAD
this.printDocument1.PrintPage += new PrintPageEventHandler(printDocument1_PrintPage);
PRINT DOCUMENT
void printDocument1_PrintPage(object sender, PrintPageEventArgs e)<br />
{<br />
try<br />
{<br />
e.Graphics.DrawImage(memoryImage, 0, 0);<br />
}<br />
catch (Exception ex)<br />
{<br />
MessageBox.Show(ex.Message,"Message",MessageBoxButtons.OK,MessageBoxIcon.Warning);<br />
}<br />
}
AT BUTTON CLICK TO TAKE PRINT
int count = Application.OpenForms.Count;<br />
for (int i = 0; i < count; i++)<br />
{<br />
memoryImage = new System.Drawing.Bitmap(panel1.Width, panel1.Height);<br />
panel1.DrawToBitmap(memoryImage, panel1.ClientRectangle); <br />
printDocument1.Print();<br />
printDocument1.Dispose();<br />
}
THIS CODE IS WORKING PROPERLY BUT IT DESNOT SHOW PRINT DIALOG BEFORE PRINTING SO PLEASE TELL ME HOW CAN I SHOW PRINT DIALOG BEFORE PRINTING AND ALLOW USER TO CHOOSE HOW MANY PRINT HE WANTS TO PRINT...

I am using an Image Control that i found here:
http://www.codeproject.com/KB/vb/PanZoomExample.aspx
It is really good and very useful. I am building a map based system and need to retrieve the mouse coordinates on the map. The 'onclick', 'onmousedown','onemouseup' etc events are not working on this 'imagecontrol'. It doesnt trigger when i click anywhere on the map except for the border near the scrollbar. I tried with the normal picturebox control and it worked perfectly. But I obviously need to use this control because of the great features.
What should I do? why doesnt the event trigger on the image. I tried what someone (splater) had suggested on the messageboard of that page but to be honest i couldnt exactly understand what he meant........ mebbe coz im using VC# and some stuff might be diff from VB. I didnt understand what the drawingboard etc was.....I even tried getting the email id of the creator of that control but wasnt able to find it anywhere.
his is what i have been doing....... but it seems the events themselves are not firing..... nd i have no clue why
//imagecontrol name: img_Map
//clickPos is a global variable
<br />
private void img_Map_MouseDown(object sender, MouseEventArgs e)<br />
{<br />
clickPos.X = e.X;<br />
clickPos.Y = e.Y;<br />
MessageBox.Show("Down");
}<br />
<br />
private void img_Map_MouseUp(object sender, MouseEventArgs e)<br />
{<br />
MessageBox.Show("Up1");
if ((e.X == clickPos.X) && (e.Y == clickPos.Y))<br />
{<br />
MessageBox.Show("Up2");<br />
}<br />
}
I am doing this as the control also has panning feature when we click the mouse and move it. So i want it to give the coordinates only when the mousedown and mouseup occur at the same position (else it is panning).
But BOTH these events do not fire when i click on the image in the control. but it does work when i click on the border near the scrollbars.
I might be asking for a little too much, but if anyone could download that control and check it out, it would really be a huge favor.

Which makes it ridiculous for you to be building a 'map based system' in C#. Someone is paying you to learn C# on the job ?
I answered this yesterday, but it looks like you're trying to take my advice ( well, it was the advice of someone who used the control before ). Assuming what they said had worked for them, I have to assume you're not hooking the events up ( in VB, they can be hooked up inline, in C# you need to do it in the designer, or in the constructor or load event ), or you're hooking them up to the wrong thing.

Hi there,
I'm looking for some advise for a generic data fetch pattern for IDataReader I'm working on, as follow:
using(GenericDataReader reader = new GenericDataReader(cm.ExecuteReader()))
{
while (reader.Read())
{
orders.Add(reader.Get<Order>());
}
}
public class GenericDataReader : IDataReader
{
public T Get<T>(string name)
{
int i = _dataReader.GetOrdinal(name);
if (_dataReader.IsDBNull(i))
return default(T);
else
return (T)_dataReader.GetValue(i);
}
public T Get<T>() where T : ILoadable, new()
{
T entity = new T();
entity.Load(this, false);
return entity;
}
}
public interface ILoadable
{
void Load(GenericDataReader reader, bool deep);
}
class Order : ILoadable
{
int id;
Customer customer;
DateTime orderDate;
DateTime requiredDate;
DateTime? shippedDate;
List<OrderDetail> orderDetails;
public Order(){ }
public Order(GenericDataReader reader)
{
Load(reader, true);
}
#region ILoadable Members
public void Load(GenericDataReader reader, bool deep)
{
id = reader.Get<int>("OrderID");
customer = reader.Get<Customer>();
orderDate = reader.Get<DateTime>("OrderDate");
requiredDate = reader.Get<DateTime>("OrderRequiredDate");
shippedDate = reader.Get<DateTime?>("OrderShippedDate");
if (deep && reader.NextResult())
{
orderDetails = new List<OrderDetail>();
while (reader.Read())
{
orderDetails.Add(reader.Get<OrderDetail>());
}
}
}
#endregion
}
What do you think? Are there any major drawback with this model I'm missing? Are there any more clever way to do that?
I really appreciate your time reading this. As long we come to a conclusion I'll write an article for CP with that we learned about it.
TIA,
Rubens

Hi,
can you please edit your post and place code in <pre> and <code> like this?:

I would consider two things.
First would be performance of return (T)_dataReader.GetValue(i); , I don't know exactly how GetValue works internally but I think that it is a bit slower than type specific method like GetInt32 becase there is more type conversion stuff. Plus by using type specific Get method you would save one of your type conversion return (T)_dataReader.GetValue(i) . Disadvantage is that you would have to use IF statement to determine which specific Get method to call.
Second thought is that I'm not sure if it is a best practice to have GenericDataReader to create businness objects. In my opinion objects like data readers should just get you a data and that is it. They should not be creating any business objects. Also I think that Business object should not work directly with data reader. It has lot of other work to do anyway. So I would suggest to create some BusinessDataObject that would take care of getting data from database, using GenericDataReader. And then any business object would just use relevant BusinessDataObject to load data.
