Point firstFormLocation = firstForm.Location;
Size firstFormSize = firstForm.Size;
firstForm.Hide();
secondForm.StartPosition = FormStartPosition.Manual;
secondForm.Location = firstFormLocation;
secondForm.Size = firstFormSize;
secondForm.Show();
I don't recommend this at all though... it'd be much better to use container controls in one form and just swap those.

Format : INSERT INTO Tablename(Var1,Var2,...) VALUES(Value1,Value2,...)
If there is one variable (Var1 as Date/Time variable),what is the format of Value1(#5/29/2006#,"5/9/2006",#29/5/2006#,"29/5/2006"). I've tested all of Value1's format.But it's still Systax Error.
Thanks

Hi, Surasaku.
I'm not sure why you're having a problem with the syntax. I just got through with some stuff using the "#5/30/2006#" format in the sql strings. Could it be that the syntax error is caused by something other than your date field?

What database are you using?
Access uses # around a date, MS SQL and MySQL uses apostrophes (').
Try using ISO 8601 format: 2006-05-29

else
trans.Rollback();
}
catch(Exception ex)
{
MessageBox.Show(ex.Message.ToString());

finally

Date is a reserved keyword. Change the field name, or if that is not possible, use brackets [] around the field name in the query.

Hello!
I have this code:
GraphicsPath path1 = new GraphicsPath();
path1.AddEllipse(10,10,100,100);
PathGradientBrush brush1 = new PathGradientBrush(path1);
brush1.CenterColor = Color.White;
Color[] colorArray2 = new Color[] { ScaleColor(Color.White, 0.25f) };
Color[] colorArray1 = colorArray2;
brush1.SurroundColors = colorArray1;
-----------------------------------------------------------------------------------
public static Color ScaleColor(Color sourceColor, float scale)
{
int num1 = (int)(sourceColor.R * scale);
int num2 = (int)(sourceColor.G * scale);
int num3 = (int)(sourceColor.B * scale);
if (num1 > 0xff)
{
num1 = 0xff;
}
if (num2 > 0xff)
{
num2 = 0xff;
}
if (num3 > 0xff)
{
num3 = 0xff;
}
return Color.FromArgb(num1, num2, num3);
}
---------------------------------------------------------------------------------------
this works fine but when i change the size of the ellipse and the width or height is zero my project shows an exception : Out of memory
Somebody knows why this happen or why can i do to fix this?

Alberto Martinez

Ventomito,
Here's a routine I keep around for such things. You'll naturally need to insert the name of your smtp server in the slot indicated. Hope this helps.
using System.Web.Mail;<br />
<br />
protected Boolean SendEmail(string strFromEmail, string strToEmail, string strSubject, string strBody)<br />
{<br />
Boolean bStat = false;<br />
try<br />
{<br />
MailMessage Message = new MailMessage();<br />
Message.To = strToEmail;<br />
Message.From = strFromEmail;<br />
Message.Subject = strSubject;<br />
Message.Body = strBody;<br />
<br />
SmtpMail.SmtpServer = "your.smtpserver.com";<br />
SmtpMail.Send(Message); <br />
bStat = true;<br />
}<br />
catch (Exception)<br />
{<br />
bStat = false;<br />
}<br />
return (bStat);<br />
}

I have a user control with labels on it.
But I need to get the click event. And since the backgroup is transparent I cant get a click.
Is there a hit test event i can do or something.
I tried MouseClcik and Click and it doesn't work
Thanks,
Nick

I vaguely remember it being possible to compare regions in GDI, and determine if they overlapped. Then use this value in a collision detection algorithm.
Is there a simple way to compare regions without using a graphics object? Or do i need to make bounding box maps and compare them?
Cheers
Tris
Update: I have regions which define the shape of objects. And depending on the entity that it represents, it will have a translation Matrix applied to it. I need a way to test whether two regions, with the relevant Matrix applied, overlap in any way.
This seems like a pretty fundamental requirement that should be doable without any kind of farting around with graphics handles etc.

Hi All,
I have a function for example, Foo(). I am implementing a FileWatcher in my project and the watcher continuosly watches a particular folder for example c:\source. Now my problem is that when more than 1 files are created at a time in this source folder, i get uneven results. I have tried to use Synclock and monitor class but i could not implement it properly. I have called the Foo() method in the event OnCreated() event handler of watcher. When for example 6 files are copied and pasted to the source file at once, 6 events are fired. This makes uneven results. What i want is that When 6 files are created at once in source folder, the events should be called sequentially for each file.
Hope i am clear with my description. Any help would be appreciated.

You may want to consider using the lock statement which is an exception safe way to provide synchronized access to a body of code. For example:
public void Foo()
{
lock (this) {
...;
}
}

Hi
I have one big solution containing C# and C++ projects.
There is a problem with compiling C++ files.
There are many errors like for example :
Error 26 error LNK2001: unresolved external symbol _fflush
Is it due to the fact that I have to choose environment settings for one language and I have chosen C#?
Is there any problem with compiling a solution containing projects in other languages in VS2005?
Thanks for help

the intellisense doesn't show the methods I have created inside TestClass.
You have to create an instance of TestClass to see it's (non-static) public members. Type
TestClass x = new TestClass()
x. and you'll see your instance methods.
Share and enjoy.
