I am working on a winamp plugin in managed c++. i have another dll referenced in my project that i need to use (in C#). Everything compiles fine, however when the dll is loaded into winamp it throws a FileNotFoundException stating it can't load the C# dll. the dll is in the same directory as the c++/cli. what do i need to do to get the assembly detected?
thanks in advance,

So the DLL is "Facebook.dll"? Does of the DLL match the one in the exception message?

Is the winamp interface to your DLL a native C++ interface? If so then there is probably some way (configuration data) to tell winamp where your DLL is right? So when the .NET runtime is loaded into the Winamp process, the .NET runtime doesn't know anything about the Winamp configuration data that points to the folder with those DLL's. The .NET runtime is using the current working folder of the Winamp process to look for that assembly, plus of course however else it looks for assemblies, but it certainly won't look in a folder that is only known to the Winamp native code.

yeah the facebook dll does match (version number and everything). you were right though, I put the facebook.dll in the directory where the executable lives (instead of the plugin directory where my plugin lives) and it worked perfectly! I always thought that the dependencies all had to be in the same folder (or else should be registered) and it had me totally messed up.
thank you so much!

Hi, all:
In VS2003, I had no problems declaring (custom control) properties that were visible in the properties window for the control - also in a catagory of my choosing (typically named after the control, itself).
With VS2008, I had to change the format for declaring the properties (to one much like that of C#). They compile without error, and can be used within the control class.
Problem is that they don't show in the properties window. Even if I use standard names. There also seems to be an insistance that I declare them as follows:
public:<br />
[Description("Some descriptive verbage"),Category("Layout"), Browsable(true)]
static property type propertyName {<br />
public: void set(type value) {...}<br />
public: type get() {....}<br />
}
The declaration as static has quite a few annoying side effects, and was unnecessary in the oldsyntax version (below).
This is not the first time I visited this problem, but now the frustration level is getting to me. How is this done correctly? I'd settle for, as above, where I have to use a predefine category, but would prefer to do as I'd done before, which is to block them together in a custom name.
Thanks, in advance,
Balboos
Old Syntax (VS2003):
<br />
public: <br />
[Description(S"Some Descriptive Verbage"),Category(S"Anything")]<br />
__property type get_PropertyName() { ... }<br />
__property void set_PropertyName(type value) { ... }

...and what were you doing wrong or needed to change? This way the next person that runs in to the same problem has some ideas on what needs to be fixed.

Fair Enough - The following will work, creating the properties and putting them in the specified category within the Properties Window for the control:
public:
[Description("Type A Description That Appears at Bottom of Prop Window"), Category("Some_Category")]
property type popertyName {
public: type get() { return dataMember;}
public: void set(type value) { dataMember = value; }
}
Now the above seems to be quite a simple change - the mess was that the early reference I found to this steered me in the direction of declaring the property static. All seemed well, although, being static, it require all of its members/called methods to be static objects, as well. This was not, for the general case, practical (and for inherited members, sanely do-able).
I figured out the error when I tried to use the property via 'hand coding': it would not let me use it as an instance, but only as a class member (because it was static - Duh!). This made me consider the static declaration not only a nusiance, but just plain wrong. Throwing caution to the wind, I deleted the (recommned via examples) static declaration and let the magic happen.
So trivial in hindsight. But why didn't the MSDN help just #*&)&&^)^ spell it out with a clear example?

Thanks. Now that the difference is clear, it does seem so trivial.

You're joking, right? MSDN docs with clear examples? It'll never happen.

Either a rhetorical question or just being cynical.
When I was first learning managed C++, I was trying to find out how to use the ExecuteScaler() method from ADO.NET - I was having trouble figuring out how to cast the value in the new syntax. Foolishly got to the MSDN help, I found an example of ExecuteScale(), but they treated it like it had void for a return type (instead of Object * which was before the current Object ^). My initial instinct was to find out if homocide was illegal in Redmond, Washington.
Another rhetorical question, then: the people who have written the 'help' - are they sadists - or just plain stupid?
Yet . . . I keep ending up going back there . . . making me wonder about myself, or, to quote Forest Gump: "Stupid is as stupid does" ????

HTTP doesn't work like that, you better do some studying. Software developers should understand the technologies they intend to use before planing how to use them, otherwise you end up trying to install a clutch in your refrigerator.

There are Mdi parent and its child form. In parent Mdi header file I include "child.h" in order to create and show it to the screen. But how to access from child any public data of Mdi parent. If I include in child.h "parent.h" it does not compile? cross reference.
parent.h file
#include "child.h"
class Parent {
...
}
child.h file
#include "parent.h" <------- does not allow to be compiled
class Child {
...
}

Look at Model-View-Control pattern[^], views should not be tightly coupled. One obvious approach to avoiding two classes being tightly coupled is to use a third.
classA classB

The manifest may only be part of the problem, if at all.
You also have to ensure all required modules/assemblies/etc.
are available on the target machine.

Thanks, but the problem was only solved when I used static linking instead of dynamic linking of multithreaded C library

In that case, you either deployed a debug build, or didn't install the CRT

Hi all
I am launching from my C++/Cli console application a child process using System::Diagnostics::Process class.
This child process throws an exception and the damned "do you wish to debug" window .
Is there any way to trap this kind of exception in my code?
Many Thanks
ManuStone

exceptions are a stack mechanism, a parent process has no access to a child process stack.
