In C# , I have upload data from CSv file to SQL Table without using CsvDataReader. is there a way to do this?
|
|
|
|
|
Why can't you use CsvDataReader? One alternative would be a combination of StreamReader and the String.Split method.

hi
What is the way to check for empty arraylist?..any one can help me ?
|
|
|
|
|
Check the .Count property.
|
|
|
|
|
yaa...i tried...but it is throwing an exception....
|
|
|
|
|
Probably your ArrayList is not created yet. Check if it's null first. Not created is not the same as empty.
|
|
|
|
|
In that case show your code and tell us what the exception says.

I am developing an windows application where i have an MDI parent form that has menu strip i want that what ever option i have select from menu strip that may effect on MDI child form.
Suppose that
I have a label control on the child form i what to change the text color of that label then i have selected the option from menustrip that is in MDIparent so how can i show color dialog from MDI parent that can work for MDI Child form...
|
|
|
|
|
I would accomplish this with events. Create events for all toolbar buttons on the MDI parent and have the child forms listen to the events that they can make something out of. That way you do not need to check if the currently active child form can handle the function that the user is clicking.

1 - everyone wants help, 'help' is not an intelligent subject
2 - yes, we can help. What's the problem ? Oh, the problem is that you have a bunch of blank methods and hope we'll do your homework for you ? In that case, no.

sorry, I newbie in programming, I still confuse about this code
if(strs[0]=="q")
break;
else if(strs[0]=="print")
PrintSortedData();
else if(strs[0]=="inc")
Increase(strs[1]);
else if(strs[0]=="dec")
Decrease(strs[1]);
else if(strs[0] == "swap")
Swap(strs[1], strs[2]);
else if (strs[0] == "ref")
Ref(strs[1], strs[2]);
else if (strs[0] == "unref")
UnRef(strs[1]);
I have already make some changes in the coding, like below :
I confuse what i should fill in Increase, Decrease and unref procedure

1 - are you using an ld version of .NET ? If not, use generic containers, always.
2 - like I said, we're not going to write the code for you. Write some code and ask specific questions when you get stuck. Working out what to do, is half of the reason you were given this homework.

If you don't understand the question ask your teacher. If you do understand it then work out what to do, I rather suspect the clue is in the method name and description -

Hello everyone,
I am new to how to use C# to calculate hash value for a string. I want to check we normally use MD5CryptoServiceProvider.ComputeHash?
As described here?

thanks in advance,

What's wrong with the gethash method that's built in ?
You can use any method you like, but I would agree you should use a built in crypto class, if you want something other than the built in method.
