I have never heard of that. As far as I know the DllImport will expect to load a DLL from one of the library directories, so I don't know of any way it could be redirected to the resources. Also why would you wish to do such a thing, it seems over complicated.

You can extract any embedded resource (something compiled in with /res: in the compiler command line or with a build action selected as Embedded Resource in an IDE) with something along the lines of
Assembly.GetExecutingAssembly().GetResourceManifestStream(filename);
If you're using Visual Studio it has a horrible habit of prepending the default namespace on the front of all your resource files, so either (i) don't use VS or (ii) adjust all your resource-grabbing calls accordingly.

No. DllImport attributes are compile-time-bound to a file (though I'm not sure if the file actually has to exist at the appropriate time). You can load a managed DLL from resources using the byte[] overload of Assembly.Load, but to access an unmanaged one at runtime is something I don't know how to do. I would set the working directory of the application to a folder you have write access to and then copy the DLL you are trying to use in there when you run (or just include it in the deployment package).

For completeness I am re-posting the following link up here.
It explains how one can load an unmanaged dll using a source besides a file. Note that this technique requires a high level of experience both in C/C++, windows architecture and file formats. And it is also likely that it could require changes based on things like OS version and probably for 64 bit formats.

But it is possible.

Is there a support for serial ports in WinRT metro style application in the Developpers preview or is there going to be in the release version.
I need to communicate with our company proprietary device. In Windows CE I did it with Windows.IO.Ports.SerialPort and used FTDI USB to serial driver and dongle.

Hi everyone,
im working on a project to detect car license plate using ABBYY FineReader Engine 10 SDK. And i would like to ask, how do i do closing on car license plate? Because i want to remove the protruding words and numbers from the car plates such that the image is 2D.
P.S, your answer is greatly appreciated And i do hope to get some sample codes as reference. Modifications will be done to given sample codes.
Thank you!!

I hate to tell you, but no one is going to give you the source code. You're going to have to figure this one out yourself.

Sadly, I have to create a COM object in C# that will be consumed by a PowerBuilder 11.5 application. Given some parameters, I need to return a byte array. I'm having trouble determining how to do this. I've tried including a ref parameter of type byte[]; no dice. I've tried declaring the parameter as "out"; again, no dice. I know the bytes I want to return are valid because I wrote them out to a file to verify. Can someone please tell me the best method to return a byte array to a calling application?

As I am new at this, and this is my first attempt at actually writing code, some of you may chuckle (or laugh out loud at the simplistic code)... please be merciful.
I keep getting the error message: A namespace cannot directly contain members such as fields or methods"
I have visited MSDN, and virtually every google and bing hit out there, but no matter how I change the first entry, I get the same message. Could someone help?

Check your curly braces... they don't properly enclose the object.

I wanted to wander back and thank you formally. I changed "product" to "muliply" and it looks like I neglected the "convert to 32" as well as my other errors.
Thank you again.

As mentioned, your } brackets are wrong and the problems starts with the ; at the end of your Main method.
namespace _11012_debproject_2
{
class Program
{
static void Main(string[] args)
{
int number1;
int number2;
int multiply;
Console.WriteLine( "Enter first number:" );
number1 (Console.Readline());
Console.WriteLine( "Enter second number:")
number2 ( Console.ReadLine());
product = number1 * number2;
Console.WriteLine( "product is {0}",product );
}
}
}
You would do well to read a bit about naming conventions. namespaces should start with a letter. Not a number of underscore.

I am having difficulty posting replies.
If this is a double, I apologize. Thank you for your assistance. My namespace "name" is a bad habit I must break (from business emails with the date at the beginning of the Subject line). Thank you for the reminder.
Also, the braces? I have no excuse for the carelessness.

Don't worry about that, Deborah. Quite a few of us have been having trouble with that for the past week or so. The site administrators are running some SQL Server scripts that are processor-intensive, and that tends to bog things down a bit. Be patient... It will get better.

Thank you for the update, I thought that 7 was wreaking havoc with my one lonely desktop. I used Vista (no gagging) with relish for so many years, that the Apple-esque features of 7 cause me to blame it for everything. I do like Stick Notes though.
Just as an update, my application runs smoothly after I fixed further code errors
Thank you again for your help.

The problem (as mentioned above) is your curly braces - the last two are commented out, as is should by them being coloured green.
If you get this kind of problem, Try CTRL+K CTRL+D - it formats your code so that everything is indented nicely. It won't work when you have missing braces, but if you fix that and try it, it should be obvious in future where things are going wrong.
BTW: You can change how Visual Studio handles your indentation to your preferred style in "Tools...Options" and then "TextEditor", "C#", "Formatting", "Indentation".
So if you prefer 1TBS:
if (condition) {
statement;
statement;
} Or K&R:
if (condition)
{
statement;
statement;
} Or Whitesmiths:
if (condition)
{
statement;
statement;
} You can get it to work with it happily. (I prefer Whitesmiths)

Thank you very much for the guidance. I will make the necessary adjustment in Visual Studio.
I appreciate you taking the time to help.

K&R is for real programmers good sir...

|

Nah. It's clumsy and inconsistent with single statement indentation:
If you write like this:
if (condition)
statement; Why would you change the indentation when it is a block you are using instead of a single statement?
if (condition)
{
statement;
statement;
} It's up to personal preference (or company practice) though - the important thing is to be consistent throughout.

I prefer K&R to 1TBS (devotees of both cults can be fanatics), because I think it's more readable, and more easily maintainable. WhiteSmith's I've never personally seen used at any place I've worked.
I maintain two simple macros in UltraEdit that will convert K&R<=>1TBS, if I should ever need to.
But, I think your "shibboleth" example code is a bit mis-leading: nothing stops you from using "pure" K&S and writing:
if(condition}
{
statement;
} Or even:
if (condition) { statement; } I've asked the braces directly how they feel about having only one statement, and they assure me they do not feel neglected or lonely
I think lack of braces around one simple and short statement, following an if-clause is seldom written with braces no matter what style of formatting you use.
Where omitting the braces would really "bother" me would be when the the single statement following the if-clause was so bloody long that it overflowed the text-working-area boundaries to be several lines long !
But, of course, you are, as usual, bulls-eye-center, when you emphasize you may not have personal choice if you go to work on some project where there are code formatting guidelines in place for all team members.
Thank goodness C# does not allow multiple statements separated by colons, or "line-continuation" characters, as in the late Pleistocene when VB roamed the savannas, and real men did not eat quiche and programmed only in C and assembly language.

Personally, I use braces round single statements, but then I grew up without auto-indenting IDEs, so it was too easy to get caught by assuming logic flow from the indentation:
if (condition)
statement;
statement; Which is one of the reasons I really dislike 1TBS: it can be far to easy to miss the opening bracket, particularly if the condition is quite long.

I prefer
if(condition) statement;
and
if(condition){
statement;
statement;
}
Only for a limited set of statement lengths (or a long condition) will I do
if(condition_which_is_quite_long)
statement;

Hello All,
Lately i saw people using the scrabulizer app, which "helps" you with the game wordfeud
for the ones not familiar with wordfeud .. it is based on the old fasioned "scrabble" game two players having stones with characters playing turn by turn trying to mke words on the playing board
the app recognizes the characters(bitmaps?) on your screen (the playing board is a grid)
and suggests the best word you can make
it would be a real challenge for me writing such an app on my own
it is a concept usable for all kind of cardgames mah-yong etc etc.
It would be a long term time consuming project, which can of course be split into all different modules
the module i would like to start with is making a grid on my screen
(a1 - k12 or something like that) in some of the boxes there will be playing cards. i would like to compare every box with a known set of playing cards (eg bit maps) and on every positive match i would like to return which card is in the box
eg it returns a5 - 9H if there is a nine of hearts in box a5
at this moment i have no clue on how to detect a known image anywhere on the screen, is there someone who can give me a hint on what search terms to google for?
thanks in advance
Jan-Willem
