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,

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

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 />

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.

I am pretty much a newbie to C# and hence REALLY need HELP! Thanks to all those helping in advance.
