i dont know about paypal or Ipn well..But again I am confused, in your code there is no information (your user name password payment information etc) what should suppose to return to your code anyway? I hope someone will solve this :(

this is not a solution, please delete

I m not sure,but I think you should (you can try without it also) because its a web request.Still no progress?

even if you want to set value at Stored Procedure you need to add this line, I think..send with null value maybe?

insert into register(id,username,firstname,... thats your procedure's line..

while in code cm.Parameters.Add("firstname", SqlDbType.NVarChar, 50).Value=txt_fname.Text;
cm.Parameters.Add("lastname", ...

id generated automaticly i assume..but there is no username parameter at button submit click??

cm.Parameters.Add( "username".. thats you forget I think

because there is an error and it is giving exception..try to insert breakpoint to begining of your code and move with F11 line by line..see which line the error occurs

where is the exception point and what exception do you get?

Convert.ToWindowsApplication(ASP.Net) in the future maybe ?

req.ContentType = "application/x-www-form-urlencoded";
is it also string? if so then double slash it again..if this doesnt work too,i will wait for an answer with you too

at least code goes to else if (strResponse == "INVALID") { line..that means an answer is coming from service..maybe you didnt provide a necessary info like password or something?

let me know if its helped?

and you can check for the escape characters :

5++;

try this

string strSandbox = "https://www.sandbox.paypal.com//cgi-bin//webscr";
string strLive = "https://www.paypal.com//cgi-bin//webscr";

string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr";
string strLive = "https://www.paypal.com/cgi-bin/webscr";

there are // and / both in strings,maybe?

150 digits and int length ??

I am not sure, it can be a memory problem..After seen your post,I m curious about Big O notation of this algorithm..if its something like n2 or worse it can cause trouble with big numbers naturally

5++;

while you are writing Hello World ,you can split your word ( Hello and World you get) and between them you can use Ahmad's code..You shouldnt rely on code everytime,just try your algorithms

you need to ask clearly and be spesific, not just with codes (and as a solution of course)..no one can guess what it does you need to tell what this codes do

possible data loss while deploying ??

you can get digit count like in this link http://www.dotnetperls.com/integer-digit-count
or of course there must be some other ways..
when you get the digit count you can put your comma anywhere you want example : http://csharp.net-informations.com/string/csharp-string-insert.htm
and if you do all this work inside DataGridView.CellValueChanged Event (http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.cellvaluechanged.aspx) you can achieve , i suppose

especially when you have a great big big array :( 5+

did you search what technologies or hardwares do you need for that first? a good analysis can bring the code for sure

there are 4.660.000 result when just copy paste your title to Google :) they are not full projects but sure they must help

you will write 1905 to cell and it becomes automaticly 1,905 while you are writing..is this you want?

thanks a lot for explanation

http://stackoverflow.com/questions/2727417/how-to-use-foreach-loop-to-edit-textboxes

maybe it helps

decimal yourDecimal=5.50;
int temp = (int)yourDecimal;//or Convert.toInt32(..) 5.50 will be 5
decimal pointAfterDecimal= yourDecimal-(decimal)temp;

i am just guessing, if you declare dropdownlist ht= new dropdownlist() public or static maybe cant you reach it from anywhere ?

constructor can be static also..there will be answers sure but i think best way debug and see

sergey is right,you are probably having problems with your algorithm not your check box?

why dont you tell them that you dont know anything ?? :S you can see from comments how is this road i hope you can do it !!! ( !!! is necessary for that really?)

can you explain how do you understand that he does not have a Windows Form ? Because of 'Myproject.frmDisplay.UpdateParties' does not contain a definition for 'toolStripStatusLabelGuestID' error ??

it must be the code is always not going to else {CurrentRecord++} block..did you try to debug mode ?

I just tried this simple code

string date = "28/02/2013";
DateTime time = Convert.ToDateTime(date);
MessageBox.Show ( String.Format("{0:dd MM yyyy}", Convert.ToDateTime(date)));

you can compare the date string with appopriate format sytle with String.Format() maybe it helps

no but i will try some little performance tests, it seemed to me useful..anyway,thanks for tip

any idea about this operator's performance?

when you write the full path ~ is needed ??

anyway,this is not an solution

i didnt get it,sorry for bad english,are you trying to do while t1 is writing t2 could not reach data received event?

i'm not sure but replying a comment as solution can be confusing? commenting sure be better

simple and correct,thanks for the link

it's so true..i love this word especially when i'm feeling lucky :)

yes grouping data must be the answer,i suppose..i am not sure if paging will make it faster anyway ?

try degub mode.writing the lines which error(s) occur will be helpful for who try to help you

there is a mistake 'ö'nmouseover ??

cHill60's second link has a good answer..Philip Rieck commented that "enums do not have to be int based"

if you've asked that how can i start and what i need to know for that application that would be so better, i think.
