What kind of file?

You can never execute a single file in a project. If you are creating a windows application, you can only execute the application itself. If you are creating a web application, you can execute any of the pages, but a page normally is the result of several files.

So, you want to execute just one cs file within one project? Is that right?

For what purpose? If it is just for testing then you might like to look at a testing framework like NUnit. While it won't execute the single file you can use it to invoke methods in the class in the file through a test fixture that you build.

NUnit comes with a number of samples to show you how it works, an a quick start tutorial[^]

You create a TestFixture class in a test assembly. This class will have a number of Tests. The test methods create the class you want to test, called the class-under-test (CUT) and invoke methods on it. You can then set up various assertions to see if the test ran as expected. If you are unsing NUnits GUI runner then you get a nice green bar if everything went okay. Or a red bar if it failed.

I doubt it. I think he wants a reference to *each and every* object that his program creates. AFAIK, there's no way to do this.

Urgent Help needed for reflection

5-Dec-05 14:26

FieldInfo[] fi44 = obj.GetType().GetFields();
for(int j = 0; j < fi1.Length; j++)
{
object obj3 = fi44[j].GetValue(obj);
}

I am using this code to retrieve objects using reflection. For certain values of j the object is of type System.Array. I want to retrieve the individual elements in the array. If i use the quick watch tool i see that the obj3 has elements defined as obj3[0] in the quick watch window.

How do i go about converting the object obj3 into an array if it is of type system.array.

Any help or references will be greatly appreciated.

thanks

What's up with this new Loader Lock exception?

dxben5-Dec-05 12:10

I'm getting an exception that looks like below when my debug C# app calls
into my debug C++ dll (which uses the MS CRT, debug dll).

Apparently if I go to the Menu>Debug>Exceptions>Managed Debugging Assistants
and unchecked Loader Lock checkbox, the exception goes away but I get a
message saying that I'm trying to use a dll that's loading the CRT without a
manifest file.

This must all be part of this new manifest side-by-side stuff that is
introduced in VS2K5. However I am not getting this problem when I run the
release build of my solution and I cannot for the life of me figure out what
Microsoft wants you to do here. All I want to do is call into my dll, why has
this become so hard to do in the new version of VS.NET ??

Loader Lock was detected:<br />
Attempting managed execution inside OS Loader lock. Do not attempt to run <br />
managed code inside a DllMain or image initialization function since doing so <br />

Compile the assembly with /NOENTRY (IIRC). IOW you cant use managed code inside DllMain.

Well that changed the way the error was thrown, but it looks to be throwing the same error.

Here's what it is saying:

Managed Debugging Assistant 'LoaderLock' has detected a problem in 'D:\Dev\throwaway\pinvoke\pinvoke\bin\Debug\pinvoke.exe'.<br />
Additional Information: Attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.[/code]<br />
<br />
Here is what my DllMain looks like, but again why isn't this happening with my release version?<br />
<br />
<code><br />
BOOL APIENTRY DllMain( HMODULE hModule,<br />
                       DWORD  ul_reason_for_call,<br />

Calling a Win32 api in C# - urgent!

spellman5-Dec-05 10:59

spellman

5-Dec-05 10:59

I need to call three C++ methods from C# which are defined as follows:

initHdr(HDR **hdr)
readHdr(HDR *hdr)
freeHdr(HDR **hdr)

The HDR struct is defined as follows:

typedef struct HDR {
long hdr_size;
unsigned char *hdr_data;
}

initHdr - mallocs hdr and hdr_data.
readHdr - fills hdr_data.
freeHdr - frees hdr_data and hdr.

I am trying to write a test program in C# that calls these three methods and use the data.

Any suggestions on the best approach to take, and how to declare the struct in C#. I'm struggling with how to declare an unsigned char pointer in C#. I thought that "unsafe" allowed you to declare C++ types, but I wasn't able to do it.

Thanks, Cindy

Cindy,

First, have a peek at PInvoke.net[^]. It's a great website that can help you out with lots of examples of calling native code from managed code, which is what you're trying to do.

Secondly, the unsafe keyword just lets you use pointers. It doesn't allow you to write C++ types in C# code.

So go look at PInvoke.net, as you'll find examples of how to marshal things like unsigned character pointers properly. If I were to guess (and this is only a guess), try something like

[System.Runtime.InteropServices.StructLayout(LayoutKind.Sequential)]
struct HDR
{
   int hdr_size; // keep in mind, a C++ long is a 32 bit integer, which C# calls int. C#'s long is a 64 bit integer
   string hdr_data; // Not really sure what's the best way here: some people use ushort*, others use string or even StringBuilder. Depends on what you're doing with hdr_data, and whether it needs to be returned to managed code.
}

CodeDomSerializer and Custom Control

Dmitry G. Vorochek5-Dec-05 10:07

Dmitry G. Vorochek

5-Dec-05 10:07

Hi I've got a problem with CodeDom Serialization. Could anybody HELP me?
Please spend some time to read the description 'cause I spent 5 days to find clasic solution and I don't have it yet. Smile | :)

I've got custom control:
[DesignerAttribute(typeof(MThemeControlDesigner)), DesignerSerializer(typeof(MThemeControlCodeDomSerializer), typeof(CodeDomSerializer))]
public class MThemeControl : System.Windows.Forms.UserControl

it has property:
[Category("Appearance"), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public ControlColors Colors{get{return _theme.Colors;}}

there is ControlColors class declaration:
[TypeConverter(typeof(ControlColorsTypeConverter))]
public class ControlColors
{
..........
public ColorSet AddColorSet(string Name, ColorSet BaseColorSet) {....}
......
}

I would like to have next code into Form Designer generated code:
this.mThemeControl1.Colors.AddColorSet("ColorSet1", this.mThemeControl1.Colors.ColorSets["Default"]);
It isn't so difficult, BUT:

When I try to switch to Design mode, I've got an exception:
C:\Work\C#\WindowsApplication1\WindowsApplication1\Form1.cs(65): The designer cannot process the code at line 65: this.mThemeControl1.Colors.AddColorSet("ColorSet1", this.mThemeControl1.Colors.ColorSets["Default"]); The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again.

When I try to trace Deserialize method of MThemeControlCodeDomSerializer - i cannt do i 'cause exception throws early. When I try to trace any method of MThemeControlDesigner - the same. Frown | :(

HELP me please! What shall I do?

I didn't apply Serializator code 'cause it's very simple code, just append some CodeStatement expressions (...MethodRefenece and like this...)
