I want to ask some question about vb.net and c# . I had created dll file that write in vb language and I want to used in c# project Its possible or not if I do that!
thank you for all that give some advice me !!!

Yes it is possible. Once its compiled it does not matter if it is in VB.Net or C#.Net you will still be able to make use of its functions from within another class. Just make sure you reference the DLL correctly.

Hi, like musefan said, it's possible
But, I'm wondering.. why didn't you just go ahead and try it?

Though, you have already been answered. It would be nice to read a bit about this[^].

Well, the question is answered. But I'll try to add more pointers.
Your query can come into picture only when the DLL was written in a native language, but needs to be consumed from within a managed language (or the plain old VB thing) AND which Calling Conventions[^] were used to export the functions from within the DLL.
While you write a DLL with any of those managed languages (or the plain old VB), it is always a COM DLL (You cannot write a Win32 DLL with VB, but you can write a COM DLL with C/C++).

Use the WHERE clause in the SQL itself. It would trip the the number of rows returned.

Are you really displaying the 2000000 all at once?
If not, use the paging instead and get the number of rows from the SQL on each page change.

Just to expand on the other post, loading 2 million records will take some time, paging would be your best bet to improve performance for loading, but for filtering 2 million records I don't see how to improve that bottleneck...

What possible use to an application user would there be of showing 2 million records? Do you ever go past page 5 on, say, search results at google?
Display what the user wants to see, not everything in the database and expect the user to trawl through hundreds of pages looking for the record he/she wants.

iTextSharp (.NET) and libHaru (native language) comes to my mind. But I'm not sure if they allow you to extract "specific data" from a PDF file. You might be able to extract the whole contents of the file and you can create a text file out of this extracted data.

Hi
I have two projects, A and B. A is referencing B. And I want to compile programmatically in the project A the referenced project B to a DLL-File.
How can I do that?

By deploying the command line compiler, and running it with Process.Start, I guess. Why do you want to do that ? I'm not sure what changes you can make to the dll and have your reference still work.

Wow! Thanks for that fast answer! 
Hm, could you explain that more detailed, because I am kind of a newbie in all that compiling stuff...
I am part of a team and my part is to compile this DLL, based on the interface definition

I just glanced over the link you gave me. Seemes to be good help.
But in my case, it's the user who is generating this DLL dynamically.
In the article you gave me, it is described how to compile the DLL by giving the source files (.cs) as parameters. But when I release my application the user just gets a .exe file of the application, without the .cs files. How can I compile the project without the given source files, just the released .exe file?

You can't....there would be nothing to compile! What exactly are you expecting the user to compile? If they already have a compiled exe and no .cs files what more could they want?
|
|
|
|
|
Hmm ...
The aim is to have a DLL consisting just one of those projects -> the second one which is refered by the first one. The user selects a XML-Definition file which is going to be a ressource and than it generates the DLL.

Hi,
Can anyone urgently tell me or maybe have example on how to be able to access Microsoft Outlook Calendar and allow a User Group in Exchange to Edit or add on of from the Calendar? Please help me urgently...

Read the guidlines on how to ask a question to get the best results. Asking for urgent responses is not one of them. All here are volunteers, if you need urgent support get your CC out and visit one of the paid support forums.
You might also try doing some research[^]
I assue you want to do this from C#, in an application you have created, you do not say!

Sorry. First time on your forum. Yes, I need to do this from C#. It will be used in a web application created in Visual studio 2005. I need to acces Outlook Calender and allow a specific user group in exchange to be able to edit or add to the calender (Shared calendars from users) and onother group to only view the shared calendars from specific users. Can anyone help me?

Web based MS Exchange is probably mostly already done. See here[^]
