The article shows the use of extension methods and the presented Merge method doesn't merge the two list as you're planning to do it. It only appends the elements of the second list to the first one.
In your case after the merging List1 has a different type (3 values per entry instead of 2). Of what type are the elements of these lists? By what you provided it seems they all are of different types, so I think it would be best to create a third list by iterating over the first two and creating the elements of the third list from their elements.

List 1 has class with construcors so yes we can reuse List 1 in my case.
List1(int, string)
List1(int, string, int)
So Im wonder HOW to merge these two lists. Like Joins in SQL
please any idea

I think the best would be iterating over the lists and either create new items or assign the second int if accessible.
for (int index = 0; index < List1.Length; index++)
{
List1[index] = new Class1(List1[index].firstIntVar, List1[index].string, List2[index].SecIntVar);
List1[index].SecIntVar = List2[index].SecIntVar;
}

well guys hello!!
jus wanted to know that there is compiles project i got from my senior, but it has not database and gives me errors, i feel like not makin whole of the tables again.. i found there is a file with .pdb extension in debug folder, "program debug database" .
Is it the real database, or what it is ??
can u help me guyzz
<<realin wuz="" here="">>

As the name implies the pdb-file holds information for debugging (afaik to give you filenames and linenumbers if errors occur). So either you get the "real" database from your senior or you'll have to rebuild it.

All jokes aside, what do you mean by that? There are many sources in the internet that provide completed projects for certain purposes (CP is only one of them).

Do I understand right, that you're looking for a task or project to program yourself.? If so, I can't imagine that there's nothing floating around in the internet. Even in this forum almost every day someone post a homework task and asks how to do it. Also most books provide some practising tasks or at least some sample projects which you can try to rebuild on your own.

I created cab files to use as updates for my app, the problem being that once the user recieves the cab file, he has to extract it to the installation directory of my app, is there someway I can automate this with some kind of selfextracter, so the user only double clicks the file and it copies automatically to the relevant directory.
Thanx in advance

Don't know if there is any such thing for cab arhcives but WinRar will let you create self extracting archives with several nice options.
|
|
|
|
|
How would winrar be affected if my client doesn't have it installed, will it still work??
He who laughs last is a bit on the slow side

|
|
Yes. The resulting executable will contain everything he needs including the decompression algorithm.
|
|
|
|
|
Thanx for the reply
You mean from the winrar? Do I need to distinute winrar with my app or does windows automatically recognize it and know what to do?

No you do not need to distribute it. You create the self extracting archive on your machine. It will get the extension .exe and thus it can be started like any other setup/application. Nothing special has to be installed on the target machine for this to work.

|

Many thanx for your help, do you by any chance know how to distribute the msde with the app installer.
I was looking at the merge modules, but looks quite hectic and I'm struggling to get orca.
Then I read that microsoft no longer recomends the use of merge modules, they talk about using a bootstrapper to initialize the setup.exe of the msde, and that a whole new chapter for me.
Thanx again

Hi,
Please also tell me how can I take a backup of an Access database in c#, I am developing a desktop application not a webbase application.
Regards
|
|
|
|

Simplest way I can think of is copying the mdb-file.

Hi,
dear thanks for your suggestion about backup of an access database but i don't want to use this copy-paste method, I want to use orignal method for creating access database backup??????
Best Regards,
|
|
|
|
|
AFAIK there's no such "original method". So have to either copy the mdb-file or create some backup functionality on your own.

hello,
thanks a lot for your reply, dear once i had seen such kind of backup in an oracle database, he was creating a file which was in unreadable format and recovers the whole database so is there any possibility of such kind of "Backup"?

Hello,
I am developing a project in c#, I am going to show data in a datagrid, I have some child records under some of main records I want to show child records under + sign navigation against specific record, I am using Dataset, I don't know how to do it? please tell me if anybody knows, It will be really great for u................
Thanks and Best Regards,
AbuBakar Malik

Have a look at the Relations property of DataSet. It has several add methods where you can specifiy which column of a child table matches which other column of a parent table. Once this is done and you have bound your DataSet to a DataGrid the navigation will work 'automagically'.
