You need a + to concatenate strings.

Yes, that will happen, because you are referring to the same checklist object all the time.

You need to cast the current enumerated object to what you put in there, and then get the value.

That depends on the data type you passed into it.

I am willing a create C# windows application and wanted to distribute it through internet.But I came to know the the .net assemblies can be decompiled.There are so many Obfuscaters avilable but i don't have money to buy that. Can anybody suggest anything other than Obfuscaters.

I believe VS 2008 comes with a obfuscater community edition which will be free.

No. But by asking this question, you likely will not need one. If you have some serious IP to hide, write it in C/C++.

If its something ground breaking, get a patent. You wont be able to stop someone 100% from reading your code.

Why are you worried about people seeing your code anyways?

Gareth.

Don't say some bullshit if you don't know the answer.
Every company is concerned about their source code.
I am creating a product by after a lot of hardwork.
Someone simply decompiling my code a creating a new version of it.
what is the meaning in that.

You do know that IP stands for Intellectual Property, don you? That would be the only thing that you would really want to protect in the first place.

Hi,
The code below gives this error:

Cannot implicitly convert type 'System.Collections.Generic.List<DataAccess.clsSetting>' to 'DataAccess.clsSetting'

Any thoughts please?

DataAccess.clsSetting s = DataAccess.clsSettingDB.GetSetting(strSelectedItem);

'in case you would like to know what GetSetting does:

public static List<DataAccess.clsSetting> GetSetting(string strSelectedItem)
{

//some code here...
return genericlist
}

DataAccess.clsSettingDB.GetSetting returns a List<DataAccess.clsSetting> and you are trying to assign to a DataAccess.clsSetting object. That is the error.

Using a C++ LIB in C#

indogerman3-Jul-08 1:21

Hi Guys,

A vendor of ours has given me the source code for one of his applications. This is a MFC based form (in VC++) which uses the vendor's own .lib file for its actual functionality (i.e. actual communication with device).

Now I need to make a similar application but in C#. For this I need to take the LIB file as provided with the source code, and use it in my C# application.
But I cannot find anyway to do this. C# only binds DLLs, right?

I tried to wrap the LIB in a DLL (MFC shared), but since i really dont know how the lib is made, and moreover, the lib gives out some enum datatypes from its functions (as paramter & return types), i am not able to successfully create this DLL.

Does anyone know any other way for using a C++ LIB in a C# App??

Thanks a lot guys!

Compile the C++ code with the CLR compiler flag, also add some managed C++ wrappers in there to expose to .NET. Simply reference the new assembly (yes, its an assembly now, not just a DLL).

Need help coding a MathML to C# converter

I'm working on an open-source project, writing a program to convert MathML (from, say, Word 2007) to C# code. I need help with coding and therefore would like to ask whether anyone is interested. Details of the project can be found here: http://www.codeplex.com/mmlsharp[^]

It seems you already have 2 active developers. I have been working solo on my opensource projects for more than 5 years, and never needed help (yes, time is what I do need! Poke tongue | ;-P

).

I just downloaded the code. Is that all of it? I dont understand why you need help with coding the project. Maybe you just need to be more patient Smile | :)

Well, there are lots of really nasty tasks - some of the features I'd like to have are hell to implement. BTW, what do you mean by 'viral license'?

byte[] to ArrayList

Rick van Woudenberg3-Jul-08 0:10

3-Jul-08 0:10

Dear all,

I'm stuck once again and calling on you for aid. I want to convert a byte array to an arraylist. I managed to write some code that will put my byte[] data in a file :

Byte[] result = (Byte[])foundRows[0]["bin_file"];
using (BinaryWriter binWriter = new BinaryWriter(File.Open("@C:\test.txt", FileMode.Create)))
{
    binWriter.Write(result);
}

This works fine but I would like to write it to an ArrayList so I can process it from there. Reading it back from the file into an ArrayList seems unlogical for me and unneccesary too.

ArrayList list = new ArrayList();
StreamReader se = new StreamReader("@C:\test.txt");
string line = se.ReadLine();
while (line != null)
{
    list.Add(line);
    //Read the next line
    line = se.ReadLine();
}

se.Close();

Can somebody point me in the right direction on how to tackle this problem ? With other words, how can I put my byte[] data directly into an ArrayList.

Kind regards,

Rick
