Hello everyone. It's me again. I am working on this project and I want to save information to this datatable, and when the user clicks submit, it should be saved into another datatable. The only problem is everything gets reset, so I was wondering if anyone knew of a way for that not to happen.
Sincerely,
The Major Rager

Set the data in your grid inside a !IsPostback block.
if (!IsPostback)
{
grid.DataSource = .....
}

Hello, thanks for replying to my question. The thing is however, that I want the user to click the submit button, and when the user does click it, the information that is in the temporary datatable should be stored into another datatable. So that !IsPostback would not work for me.
Sincerely,
The Major Rager

Not using IsPostback is the reason your table is being reset every time. You can copy the data in your event handler, but unless you make sure it's not reset every time using ispostback, it will be.

Sori for the no-brainer commet but that's the 1st time i've seen Christian Graus post an actual code. Must be in a good mood...
But i totaly agree...by not using IsPostback, everytime you refresh the page everything resets to what you initialy set it to and thus does not display whatever changes you have made

Really ? I post code all the time, in fact I ran up a VB project to write some code to help someone earlier today.
But yeah, I find I tell more and more people to use google. Not to be rude, but to be honest, because it's not helping them to tell them anything else. every developer needs to be able to do some research.

Hello, thanks for replying to my message. The !IsPostBack does not work in my case, because when the user clicks the submit button, it goes to the form load and it is a post back, so it does not get stored to the datatable.
|
|
|
|

I don't get it. The code to load the initial data to the form goes in the !IsPOstback block, not the code that you WANT to run on postback. That would go in an else block, surely ?

You may try to store it on a local database or a file to be not reset,or if its not so much data you may store it in the Session collection till you copy it and then delete it again.

I need the user from windows, so i can ot get that because when i use Environment.UserName it returns ASP.net, i do not want that, i want the user that made a logon on windows, so if exists an API from windows that returns that, or any class from asp.net, please help me.

Your page will be executed under the ASP.NET account, so all methods that return the current user name will return ASP.NET.
You could try to get the user who started explorer.exe (process.StartInfo.UserName)

Hi ALL.
In C++ the const value write in *.h file (header).
I have a lot of const values that i need to include in my code , i can open new *.cs file and write them all in it - but does C#.NET support some file like *.h (header ) file that will contain all my const values ?
Thanks for the help.

I think you're doing it the right way. There is no concept of a header file in C#.

No. Put them inside your class, or create a class that contains them if you like. Make them static.

I'm keying a table on filename, and would like to preserve capitalization for the user since spaces aren't allowed in the name (ie FileNameWithMultipleWords). I'm using a filesystemwatcher to detect when other instances of the app modify the file to update timestamp info internally. The problem is that the fsw returns an all lowercase filename (the remainder of the path is properly capitalized), and 'FileNameWithMultipleWords' doesn't match with 'filenamewithmultiplewords' when I look for the old record.

No, you can't force the hashtable keys to be case insensitive. You can, on the other hand, force the keys to be lower case when you create the table entry. Just call the .ToLower() method of the filename string to return the lower-case version of the string before you put it into the hashtable.

That's what I thought, I'm using the filename as a the key though, and was hoping I could preserve the capitalization for UI use without having to modify my datastructure though.

You can use the lowercase version of the filename as your key, but store a structure in the value portion that contains the original filename with casing.

My issue wasn't with the drive letter but the filename itself. While I did have a hack to do the equivilant of the above it ended up affecting code elsewhere and I wanted to preserve the capitalization because WordsMashedTogether is easier to read than wordsmashedtogether.

I haven't tried it, but there is a
System.Collections.Specialized.CollectionUtil.CreateCaseInsensitiveHashtable method.
It looks like Hashtable takes an IHashCodeProvider and an IComparer in a few of its constructors.

Hmmm.... Never looked down there before. I'll have to experiment with that a little bit.

That simplified things somewhat, but not a lot since I still need to get the mixed case version of the name when adding a new file, and when updating a new one. Because of the smallness (a few dozen files max) of the dataset I'm iterating across the entire folder/keyspace rather than trying to modify the datastructures since I'm not 100% conversant with how that section of the code works.

I wanted to know if anyone has the program for Graph Coloring or Map Coloring using Forward Checking.
