Hello,
I'm still really confused, so I tried this
<pre>
IEnumerable<string> carnames = from cars in Car
select cars.name;
</pre>
The error I get is error CS1936: Could not find an implementation of the query pattern for source type 'CaraPartnersSdk.Robot'. 'Select' not found.
I'm real confused I just want to print out the string name of the car. Please help.
Best,
Adrian

To enumerate an enumerator, all you need is a foreach statement.
I'm also assuming that FindByName can take a wildcard.
But, as you still haven't told us what error you were getting, we still don't know!

Hi,
I have some hands on experience in developing .net web applications .Now i am thinking about developing components (Like charting components,HTML to pdf etc) which can be referenced in .net applications. For eg like the one mentioned in http://www.dotnetcharting.com/[^] . I know it will take time and effort to create stuff like that . But i want to the basic steps in developing components like this . Is these are com components? (C++) or can we develop the same in pure .net code?
Thanks

Hi all,
I am using Visual Studio 2005/2008, I tried to use the OpenFileDialog to open file.
But I would like to know what codes/settings do I need if I want to let the users only select one floder and all files in it would be opened?
Thanks very much!

Hi,
how about using the FolderBrowserDialog class to let the user choose a folder, then use Directory.GetFiles() to get a list of all files, and finally open those files in whatever way you think appropriate, either reading them yourself inside your app, or launching them with Process.Start()

Thanks Luc!!
It sounds link a good solution for me! However, I am really too lack experience in write such a program.. I got a warning of "No overload for method 'GetFiles' takes '0' arguments..
How can I resolve this?
|
|
|
|
|
whatever the problem is, there are three steps to a solution:
1. read the documentation (in this case, it will tell you GetFiles takes 1 or 2 or 3 parameters);
2. if that did not work, search the web, i.e. ask Google
3. and if that failed too, ask on a forum like CodeProject.
FYI: if you're new to programming language, or to programming in general, I strongly advice you to buy a book of your choice, and study it thoroughly. That will teach you the fundamentals, in a structured way, and at a much higher pace than you can achieve by experimenting and asking around.

Thanks =p
I would try to google more and search on the msdn page. My project is quite urgent that there would be no time for me to read a book =\
Thanks again Luc!

When i display a Cursor object in a property grid i get a dropdown menu with all the custom cursors and associated images. Is there a way to do this with a custom object so i can display custom images in the same format.
I have found an article on this site that give a way to display little rectangle images in the property grid but the cursor images are different. with the cursor the images are larger and square they are also not shown when the dropdown list isnt shown.
Can anyone tell me how i can imitate this effect with a custom object or maybe help me to modify the Cursor object to show custom txt and images.

good day to everyone. i just want to know how to hide tables in ms sql using c# codes. because, i want to hide the tables so that no one will be able to edit or even delete the tables i've created.thank you very much in advance...

accessing a database can be restricted using usernames and passwords.

thanks for the reply...but is there a way to hide the tables just for add-up securty?thanks again...

I don't think so, and I don't see a need.
Create your app with the functionality you want, and no more; give it a connection string that provides access to the database; and store that connectionstring in a settings file, outside the app, but encrypted, so the world can't use it, only your app can.

Assuming your Web Service runs in IIS, give the user account executing the web service AppPool permissions to access the database table. Do non give these permission to any other user account (excpet administrative account).
Doing so the access to the table will be possible only through your Web Service.

I guess Google is not available from where you are at.
This is such a simple question that you could most likely stumble blindly in any forum and find the answer.

I am currently a student and really enjoy programming, mostly in C#!
I don't really get told much about the "real" software development world and thus I would like to know some of your experiences or advice for real world programming!!!
Thank you!
