that works thx!

That's a hack. You should instead figure out what's going wrong with the zip library.

Well, I'd think if it's a problem in the framework, then others will have encountered it. If you find nothing on google, it's a bug in your code. 'If we have time at the end', means, we're going to leave it broken. At least, that's what I'd expect it to mean.

What do you mean with that?

hello again,
well I made a parent child form in C# 2.0 windows application with sql server 2000 and i'm having troble in deleting the parent record bcz it gives a constraint error that the table is also reffered to in another child table that is not being used in the current form. so can u plz tell me what I should do to delete that parent record when there are references in its child table.
thanks in advance

i have also face the same problem in java.
At that time i have to delete the record from the child record and then to the parent node.
U can't simply delete parent record.
Try this out and let me know.

This isn't strictly true. You can do a cascading delete, but only if the database supports it and the tables have been set up to support it. I wouldn't recommend it, but you can.

If some constraints are specified between two tables. How do to overcome the constraints.
If the above sentence is true means. How do you delete the data with deleting the data from the child record.

It works by setting up a cascading delete on a foreign key. Basically, this means that when you delete from the master table, related entries are deleted from child tables. In SQL Server, you do this by adding ON DELETE CASCADE to the foreign key constraint.
As I noted above though, it is generally best to avoid doing this. You really need to have more control over what you are deleting because sometimes you may end up deleting things that you didn't want to.

well yes I didnt have the cascade option there but now I think its a better idea to have more control over it bcz these tables are bill and billDetails so one shouldnt be able to delete the whole bill along with all the detail records. Right?

|

well I have a little question: how do we chk for the existance of child records in C#. is it something like getChildRows() or something??
|
|
|
|
|
You actually need to query the tables that are linked to see if they point back to the row.

draw an organization chart on a form but the rectangles I drew exced the size of the form what can I do to make the form sizable

Look at Form property -> FormBorderStyle
If you can't find time to do it right the first time how are you going to find time to do it again?

EDIT2: Solved, thanks to CPallini. I was stupid not to see it in the first place myself. 
EDIT: The code that generates the random bools is in a different assembly from the code that calls it - caching is unlikely to work. Due to design constraints, I cannot change GetRandomBool's signature
I am trying to generate pairs of bools in a loop. Here's the relevant code with method and variable names changed:
for(int i = 0; i < rounds; i++)
{
bool firstPlayersChoice = GetRandomBool();
bool secondPlayersChoice = GetRandomBool();
}
public static bool GetRandomBool()
{
System.Random randomNumberGenerator = new System.Random((int) DateTime.Now.Ticks);
int randomNumber = randomNumberGenerator.Next();
if(randomNumber % 2 == 1)
{
return true;
}
else
{
return false;
}
}
When I step through the code, executing the program step by step, the results are fine. However, when I run the program directly, I'm seeing pairs of the same value, i.e., many instances of (true, true) or (false, false). Statistically, half my outcomes should be identical pairs, but even when rounds is 100, I barely see a non-identical pair like (true, false). 
I'm guessing the program runs so fast that the two calls to GetRandomBool generate identical values for randomNumberGenerator and hence generate identical bools. 
Is there some way I can get bool pairs that are statistically similar to what I'd expect?

I think you get the same Ticks twice.
Have you tried re-using the random number generator?
for(int i = 0; i < rounds; i++){
System.Random randomNumberGenerator = new System.Random((int) DateTime.Now.Ticks); bool firstPlayersChoice = GetRandomBool(randomNumberGenerator);
bool secondPlayersChoice = GetRandomBool(randomNumberGenerator);
}
public static bool GetRandomBool(System.Random randomNumberGenerator){
int randomNumber = randomNumberGenerator.Next();
if(randomNumber % 2 == 1)
{
return true;
}
else
{
return false;
}
}

I think it's a better idea to reuse more times the random generated sequence,

Thanks for the reply, Coco. Unfortunately, I have some constraints - I cannot modify GetRandomBool's signature. You see, it's a method in a different assembly that is called using a superclass reference. I've updated my post to reflect the constraints.
I'd appreciate any help.
Cheers,
Vikram.

You should NOT restart the number generator sequence each time your GetRandomBool is called.
I suggest the following changes:
System.Random randomNumberGenerator = new System.Random((int) DateTime.Now.Ticks);
for(int i = 0; i < rounds; i++)
{
bool firstPlayersChoice = GetRandomBool(randomNumberGenerator);
bool secondPlayersChoice = GetRandomBool(randomNumberGenerator);
}
...
public static bool GetRandomBool(System.Random rg)
{
int randomNumber = rg.Next();
if(randomNumber % 2 == 1)
{
return true;
}
else
{
return false;
}
}

Thanks for the reply, mate. Unfortunately, I have some constraints. Please see my original post (I've updated it). Would appreciate assistance.
