The regular expression "^[^\.]+$" matches a string that is at least one character and has no periods.
Experience is the sum of all the mistakes you have done.

This regular expression gets all ordinary characters plus the . character.

if (char.IsNumber(e.KeyChar) == false)
{
e.Handled = true;
}
write this in the key press event on a textBox then it will allow only integers

Hi,
Consider the following class:
class A{<br />
private int i;<br />
private int j=8;<br />
private int k;<br />
{<br />
int i =j;<br />
}<br />
public Test1a(int k)<br />
{<br />
this.k=k<br />
}<br />
}
...
program is not complie why?
|
|
|
|
|
Because you missed a semicolon after this.k=k?

Just curious: But didn't the compiler tell you that there was a missing semi-colon? If not what did it say?

Argghhhh - it was an examination question. Really, do we want numpties like this unleashed on the workforce if they can't spot something simple like this?

In the OP's defence *takes own temperature*, before the compiler warned about missing semi-colons I could be looking at the screen for ages before spotting it. This was especially true in Borland's Turbo C++ (The fist C++ compiler that I used which was DOS based) as it would find fault with everything after the line with the missing semi-colon because it would just get really confused. And I spent ages tracking down dozens of errors that didn't exist.
However, given the small size of the code, it should be easy to spot a missing semi-colon.

Ah, but experience in those days used to show that clearing one error would normally clear a couple of hundred errors, which was why I always used to start at the errors at the top of the failure to see if they could be the culprit. 9 times out of 10, the error was in the top 2.

put semicolon at the end of the statement
this.k=k;

HI ,
i want to know how to create a class which has an INSERT method for several forms.
for example: i have 3 forms , FORM1,FORM2 FORM3.
FORM1 has 3 textboxes.
FORM2 has 7 textboxes .
FORM3 has 20 textboxes.
Each textbox contrl has datas with differen datatypes.i want to create a common class with INSERT method which inserts data in different table for its corresponding calls made by every forms.
i had already done this task but seperate INSERT methods for individual forms.
now if i try to user a common insert method for the 3 form with diff contrls and datatypes, i cant get a clear idea to accomplish this task.
can anybody give me solution.
thanks

First "Happy new year to all"
I am using listview control of c#.net 2003,
And when i am updating the list with data from database it giving the
System.NullRefrenceEXception error.
What can be the problem?
Is the data not fetching up from DB, or I am not linking it properly?
And How can i analyse this?

Wow, that was rude. You expect people to help you when you act like that?

its because the app is nt getting the reference to the control . please check whether you added and the control. check its initialization also.
My small attempt...
|
|
|
|
|
if i dont bind/call the DB function, then its displaying the blank list properly, but when i call the function it shows error.
Are you saying, that the data from database not binding properly to list items??
|
|
|
|
|
you are getting error where you try to give data right???
the error means the reference to that list is not there
My small attempt...

Removed due to rudeness by OP.

byte[] byteData = null;
string CH, GET, PATH, XML;
m_Client = new MCLClient();
UTF8Encoding utf = new UTF8Encoding();
byte[][] Settings = new byte[4][];
Settings[0] = new byte[aName.Length];
Settings[1] = new byte[aMethod.Length];
Settings[2] = new byte[aPath.Length];
Settings[3] = new byte[aData.Length];
//encode
utf.GetBytes(aName, 0, aName.Length, Settings[0], 0);
utf.GetBytes(aMethod, 0, aMethod.Length, Settings[1], 0);
utf.GetBytes(aPath, 0, aPath.Length, Settings[2], 0);
utf.GetBytes(aData, 0, aData.Length, Settings[3], 0);
gchRequest = GCHandle.Alloc(Settings, GCHandleType.Pinned);
MPACKET Packet = new MPACKET();
//fill packet with send buffer
