when you use the MySql QB what value does it use to populate the field? and I would have to see the code you are using to call the MySQL procedure.

Here is the c# code that calles the stored procedure:
public void createUserProcedure(string uId, string lname, string fname, string email, string pswd, DateTime expdate, int secId, char usrStat, DateTime lgn)
{
MySqlCommand cmd = new MySqlCommand();
try
{
DB_Connection conn = new DB_Connection();
cmd.Connection = (MySqlConnection)conn.DBConnect();
cmd.CommandText = "createUser";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("USERID", uId);
cmd.Parameters["USERID"].Direction = ParameterDirection.Input;
cmd.Parameters.AddWithValue("USER_LAST_NAME", lname);
cmd.Parameters["USER_LAST_NAME"].Direction = ParameterDirection.Input;
cmd.Parameters.AddWithValue("USER_FIRST_NAME", fname);
cmd.Parameters["USER_FIRST_NAME"].Direction = ParameterDirection.Input;
cmd.Parameters.AddWithValue("USER_EMAIL", email);
cmd.Parameters["USER_EMAIL"].Direction = ParameterDirection.Input;
cmd.Parameters.AddWithValue("USER_PSWRD", pswd);
cmd.Parameters["USER_PSWRD"].Direction = ParameterDirection.Input;
cmd.Parameters.AddWithValue("USER_PASSWORD_EXPIRE_DATE", expdate);
cmd.Parameters["USER_PASSWORD_EXPIRE_DATE"].Direction = ParameterDirection.Input;
cmd.Parameters.AddWithValue("USER_SECURITY_LEVEL_ID", secId);
cmd.Parameters["USER_SECURITY_LEVEL_ID"].Direction = ParameterDirection.Input;
cmd.Parameters.AddWithValue("USER_STS", usrStat);
cmd.Parameters["USER_STS"].Direction = ParameterDirection.Input;
cmd.Parameters.AddWithValue("USER_UNSUCCESSFULL_LOGIN", lgn);
cmd.Parameters["USER_UNSUCCESSFULL_LOGIN"].Direction = ParameterDirection.Input;
cmd.ExecuteNonQuery();
}
This is how I call the procedure:
DateTime dt = new DateTime();
dt = DateTime.Parse("02/01/2007");
UserDAO test = new UserDAO();
test.createUserProcedure("test","TEST", "tst", "tst@net", null, dt, 1, 'A', dt);
Here is the stored procedure in mysql:
DELIMITER $$
DROP PROCEDURE IF EXISTS `the_vault`.`createUser` $$
CREATE DEFINER=`VAULT_DEV`@`%` PROCEDURE `createUser`(IN USERID varchar(20), IN USER_LAST_NAME VARCHAR(40), IN USER_FIRST_NAME VARCHAR(20), IN USER_EMAIL VARCHAR(50),IN USER_PSWRD VARCHAR(20), IN USER_PASSWORD_EXPIRE_DATE DATETIME, IN USER_SECURITY_LEVEL_ID INT, IN USER_STS VARCHAR(1), IN USER_UNSUCCESSFULL_LOGIN DATETIME)
BEGIN
INSERT INTO USERS VALUES(USER_ID, USER_LAST_NAME, USER_FIRST_NAME, USER_EMAIL, USER_PASSWORD, USER_PASSWORD_EXPIRE_DATE,
USER_SECURITY_LEVEL_ID, USER_STATUS, USER_UNSUCCESSFULL_LOGIN);
END $$
DELIMITER ;

END $$
Check the "Bold" values. They are different. Is this an intended difference, or is it a mistake?

I'd say that's it. Everything else looks pretty good.

Kevin, That was the issue,however why would MySQL still write this record to the table even though tere wasn't a valid USERID value?
|
|
|
|
|
Is the USER_ID field actually set as the PK in MySQL?
You say it is a varchar?
Is it set to Auto Increment?
Is set to not null?
in MySQL QB does the newly inserted value show up as empty or null?
-Kevin
|
|
|
|
|
Yes, PK
Yes, varchar
No it is not set to auto increment
Yes, it is set to not null
in mysql qb it shows up as the value that I passed to the stored procedure
|
|
|
|
|
yes, now that you've fixed it, it should show up as the value you passed. Your question was why did it allow this in the first place? Your original post stated "It populates the field with an empty string instead of the value". That was my question was the value showing up in the db as any empty string or null, before you fixed it? There is a difference. I think your application was posting an empty string and not a null value, thus passing the db's test to not allow nulls. and since you do not have the field set as auto-incrementing an empty string would be a valid unique string. You probably could not run it twice in a row since that would violate the "unique" requirements of a pk. I guess in any event it is working now, eh?
-Kevin

Yes, it is working. Your analysis is correct. It put an empty string it orig. and not the value.
Thanks for your help!

I have a few questions over speed and threading of the .NET 2.0 web browser control...
1) Which of the following is the "faster" methodology for capturing events HTML events?
a) setting up custom scripting methods (window.external with an ObjectForScripting and ScriptMethods)
b) nabbing HTML elements and setting events to them (.GetElementById() and then adding an event to it)
To me it seems that the more diversity as it can be called from any object by evoking the window.external script object, but if nabbing HTML elements is "quicker" by only monitoring one element instead of waiting on a method call it might be best.?.
2) Also do you think it'll be safe to interact with the web browser control cross thread? or should I make some type of external method in the owner class to interact with the web browser control to be called from the 2nd thread?
(I think I should do the later, but it might not be safe at all.?.)

hi friend's
i have a method that do below code:
for(int i=0;i<=max;i++)
str+=i.ToString();
i want to create two thread that call this method at a same time.
but i have a problem:
max and str are variables that difference for each thread it means that each thrad must have max and str that contain a difference value from other threads.
what i have to do?
thank you for your guide.
nobody help you...
you have to help you yourself
and this is success way.

Then don't make them static.

Hi,
don't use statics for things that are not unique at all. Instead:
make a class that contains some data (str, max) and a method containing your for loop.
have its constructor create a thread calling that method. Now instantiate two objects.
BTW: you did not specify any output, so I will assume the method ends on
Console.WriteLine(str);.
Otherwise you may need some delegate to report results to the original class.

Hi people
I have an idea for an algorithm, but am gonna need some help in actually implementing it.
What I need to do is read file paths from right to left, comparing all of them, finding the right-most unvarying element of the path.
An example of how I want this algorithm to work is below
C:\Root Dir\Const Sub Dir1\Sub Dir1
C:\Root Dir\Const Sub Dir1\Sub Dir2
C:\Root Dir\Const Sub Dir1
Path scanned was C:\Root Dir\Const Sub Dir1
Any ideas would be greatly appreciated
Cheers

How about something like this: split the string into pieces separated by the \ character. You can do this using theString.Split('\\')
Once you've split the string up into an array, you can check the last elements of the array for the differences.
|
|
|
|

It will actually be faster to just go left to right, comparing each char as you go. When one of the chars varies, return the current string (as follows):
List<string> paths = new List<string>();
int shortestPathLength;
// Populate paths and shortestPathLength
if (paths.Count == 0) return string.Empty;
string result = string.Empty;
string tempResult = string.Empty;
for (int charIdx = 0; charIdx < shortestPathLength; ++charIdx) {
char c = paths[0][charIdx];
for (int pathIdx = 1; pathIdx < paths.Length; ++pathIdx) {
if (paths[pathIdx][charIdx] != c)
return result;
}
// Not sure if "DirectorySeparator" is the property, but you get the idea
if (c == Path.DirectorySeparator)
result = tempResult;
tempResult += c.ToString();
}
return tempResult;
Hope this helps!

Yeah this helped, am now working on translating your example into my source code, gonna be a long old scan, considering am talking about 3500+ paths here

If you are dealing with that many paths, you could skip the first three characters if you know for sure they all start on the C drive. If not, you could skip only the second and third characters since you know they will be ":\" for all paths. Other than this optimization, there is no way to improve the efficiency of this algorithm since every character will need to be compared to check for equality.
Jeff

Tip:
Instead of creating a lot of intermediate strings by adding one character at a time, make result an int, put the length of tempResult in result, and use tempResult.Substring(0, result) to get the string.

Good call! In fact, you could change the code to be the following for max optimization using the previous suggestions:
int result = 0;
for (int charIdx = 0; charIdx < shortestPathLength; ++charIdx) {
if (charIdx == 1) {
++charIdx;
result = 2;
continue; // Skip the :\ from the path
}
char c = paths[0][charIdx];
for (int pathIdx = 1; pathIdx < paths.Length; ++pathIdx) {
if (paths[pathIdx][charIdx] != c)
return paths[0].Substring(0, result);
}
// Not sure if "DirectorySeparator" is the property, but you get the idea
if (c == Path.DirectorySeparator)
result = charIdx;
}
return paths[0].Substring(0, shortestPathLength);

Hi,
there is a lot of opportunity for optimizations here;
I assume you are not interested in partial folder names (i.e. C:\A\B1 and C:\A\B2 have
C:\A in common, not C:\A\B).
The candidate result initially equals the first string.
The only thing that can happen to it is you must drop everything from the last backslash
up to the end (possibly performed iteratively).
Something like:
public string findCommonPath(string[] strings) {
string common=strings[strings.Length-1];
foreach(string str in strings) {
while (!str.StartsWith(common)) {
int i=common.LastIndefOf(@"\");
if (i<=0) return null;
common=common.SubString(0,i);
}
}
return common;
}
remarks:
- you may want to do everything in case-insensitive way;
- if your strings happen to be sorted alphabetically, you should only compare the first
and last one !
- I started with the last string hoping it differs most from the first one, resulting
in a sooner shortening of common, hence less CPU cycles for StartsWith.
- if you happen to know what the shortest string is, you may want to handle that one first.
- the number of objects created is very low (in the order of the number of backslashes
in the first string)
