Hi,
I am working with a VS2005 windows application. There are some text boxes that are used for entering decimal numbers.
If user enter -1234567.8, I want to reformat it as -1,234,567.80
How can I do it, I tried to use MaskText box but could 
Thanks you!

You can use string.Format to format a number, or you can overload the textbox itself to give you the format you want, by handling events when the text changes, and reformating it. You're better off formating it when the focus leaves the textbox tho

I have wizard kind of windows application with many forms. I have set the form Location
this.Location = new Point(100, 100);
This works fine with single monitor. If the user connects to 2 monitors i want the form to be displayed in both the monitors. How can set the form Location? Also also if the user switches back to single monitor the Form should display in one monitor?

Screens.PrimaryScreen will give you the main monitor. All the screens in the collection will have locations relative, so you can position your window anywhere you like. Getting the same form to display on both monitors, is actually a setting in windows, which would make the full screen be cloned. Otherwise, you'd need to create two windows and have them mirror each other.

Thanks for your reply.
As you mentioned "Getting the same form to display on both monitors, is actually a setting in windows, which would make the full screen be cloned."
I dint understand it clearly. Do you mean to say i cannot programmatically make the same form to display on both monitors? Or i need to change same settings in the Windows. How to do this?

Well, I don't know, I've not heard of it. But, I recommend www.rentacoder.com if you're looking for full source code. Here, we help programmers who are stuck with their own code.

I am using third party control (Infragistics UltraComboEditor). Unfortunately, this control is not raising MouseWheel event with Mouse wheel is moved (may its a bug in control). How to handle global mouse wheel event?
Somehow i want to handle the mouse wheel moved event in my application, and will check whether currently the focus is in UltraComboEditor and act accordingly, is this possible?
Thanks

I have an interface library to a device and one function is defined as
unsigned short init(HANDLE handle, unsigned char* cFlag);
The cFlag is just a byte ([in] parameter), and not an [out] parameter and should not be a pointer. Expected values are 1, 2, 4.
If I create the following p/invoke...
[DllImportAttribute("if.dll", EntryPoint = "init")]
public static extern ushort init(IntPtr handle, IntPtr cFlag);
Now, how do I use it...
Case 1:
IntPtr handle = ...
IntPtr cFlag = new IntPtr(2);
int result = init(handle, cFlag);
Case 2:
IntPtr handle = ...
IntPtr cFlag = Marshal.AllocHGlobal(1);
Marshal.WriteByte(cFlg, 2);
int result = init(handle, cFlag);
Marshal.FreeHGlobal(cFlag);
Which is correct and recommended?
Best regards,
Paul.

I want two merge two tables A & B. Table-A contains column A, B, C and Table-B contains column D, E, F. I want the result table to contain columns from both tables i.e., A,B,C,D,E,F. Is there a way to accomplish this in C#? I'll greatly appreciate any response.

How do rows in the two columns map to each other, so that such a join makes sense ? Where are the tables coming from ? The most sensible thing would be to write SQL to return a table that merges the two tables together, assuming there's a way of doing that logically.

I assume that you're saying you want to merge 2 System.Data.DataTable objects into one. If thats not the case forgive me...
If this data is coming from 2 separate, but related tables in your database, you can add them to a DataSet, and set up a DataRelation between the 2 tables.
This doesn't merge the 2 tables into 1, but it will allow you to retrieve the data for a particular DataRow in DataTable1, as well as the DataRows from DataTable2 that are related to it.
You can get the related row information by calling dataRow.GetChildRows(), dataRow.GetParentRow(), or dataRow.GetParentRows()
Hope that helps...

Thank you very much for your response. Yes, i want to merge 2 DataTable objects into one. I'll try the method you suggested. Thanks again.

Hello- Please help me with the following questions, if possible,
please also provide some explanations--thanks in advance:
1) Assuming that "valid connection string" is a valid connection string, what will be the output of the following code? If the code cannot compile, please state why.
the same rules apply to this question as for the one above
using(SqlConnection sqlConn = new SqlConnection("valid Connection string"))
{
System.Diagnostics.Debug.WriteLine("Opening a connection");
sqlConn.Open();
System.Diagnostics.Debug.WriteLine("Connection Opened");
sqlConn.Close();
System.Diagnostics.Debug.WriteLine("Connection Closed");
}
if(sqlConn == null)
System.Diagnostics.Debug.WriteLine("Connection State is NULL");
else
System.Diagnostics.Debug.WriteLine("Connection State:" + sqlConn.ConnectionState);
2)The following code needs to generate a string of 1000 alternating '+' and '-' characters
Rewrite this code to make it more efficient (Note: You can use different data types than the ones present)
string htmlOutput = string.Empty;
for(int itemIndex = 0; itemIndex < 1000; itemIndex++)
{
if( itemIndex % 2 == 0)
htmlOutput += "+";
else
htmlOutput += "-";
}
3)Assuming that CustomException is defined, what will be the output of the following code?
try
{
throw new CustomException("Something went wrong");
}
catch(Exception ex)
{
System.Diagnostics.Debug.WriteLine("Generic Exception has been triggered");
}
catch(CustomException ex)
{
System.Diagnostics.Debug.WriteLine("Custom Exception has been triggered");
}
4) What will be the difference in behavior between the lines marked 'a' and 'b' during runtime? (Assume that CustomClass is a defined class)
object objClass = new object();
CustomClass myClass1 = objClass as CustomClass; //a
CustomClass myClass2 = (CustomClass)objClass; //b
5) Assuming you have the following class:
public class MyClass
{
public MyClass()
{
}
public string DoNothing(string someParameter)
{
System.Diagnostics.Debug.WriteLine(someParameter);
}
}
How would you call the DoNothing function asynchronously and provide a callback?
6) What is the difference between a Monitor and a Semaphore?
7) Architectural Question: If you have pages that perform heavy DB or File I/O, what could be done to help increase the overall performance of the application? (Asp.net only! Assume all non asp.net factors have been optimized to the max)
8) What is the difference between the following 2 statements?
try
{
throw new ApplicationException("None");
}
catch(Exception ex)
{
throw ex;
}
try
{
throw new ApplicationException("None");
}
catch(Exception ex)
{
throw;}
9) What is the difference between a List and a LinkedList?
10) Assume that you retrieve a list of 1,000,000 Person objects from a database that contain the SocialSecurityID, First and Last name properties. Which collection class would you use to store and allow for quick lookup of Person objects based on the SocialSecurityID field?
