Thanks, I did have binary compatability on, but still got new guids. However your answer led me to look at it in more detail and I discovered that the binary compatable dll referrenced had a different type lib version to the dll I was buildinf and hense generated new guids. I updated the dll reference and hey presto consistant guids.

That is pretty much what we do

I think as you say using AppDomains is the answer, but I'm have difficultly understanding how to set one up, it look as though if I load a dll to a new application domain as in my example it loads the dll to both the new domain and the current domain maybe I need to create a domain and somehow load my dlls from within it.

I think Most of the memory added is the actual size of the dll I'm loading along with all its dependancies. It is not leaking in that it does reach a maximum but since my application is run from a shared server terminal service I need to free up this memory when I'm finised with it.

I have c#.Net dll that is available through COM This .Net dll then Loads .net DLLs as shown in the loading code in my question. Problem is that when I unload the application domain it has little of no effect. I Suspect that it is not quite as simple as I first thought.

I gave you 5 for the answer, but didn't acccept it because the question was how can I do this in win32 without access to .net. I already knew how to do it the way you suggested.

It only would have been quicker if an api call existed to do this. But since it doesn't then it is not a solution. For now I've avoided the problem by using sn to get the keys the put the keys in a file which I read from the win32 console application.

not off the top of my head, any info on that would be useful I think I might revisit this at a later date, thanks

Another dirty solution I considered would be to call sn -T from my win32 application and extract the output. It does appear as though a win32 api call for this doesn't exist.

Some background to this: We have a product which is a mix of win32 binaries and .net assembles. Many of the win32 modules use COM. Some .net modules are called through COM, and call some win32 modules through COM. Problem is we don't want a COM/Registry dependancy for deployment reasons, so we have to generate sidebyside manifest files and run the application COM free. We have 2 tools that generate the manifests Regsvr42 (win32 C++ console app) and GenMan (.net and deals with .net assemblies) The main exe is a win32 application so we use Regsvr42 to generate this manifest. In this generated manifest are listed all the dependancies of the exe some of which are strong named .net assemblies. Thus my question, regsvr42 is a win 32 console application written in C++ and compiled with /mt (so is incompatable with /clr i.e. cannot access .net)

Avoid using .NET in this instance I was looking for a quick solution that could be used with my application's existing win32 /MT environment. Otherwise I would have just converted the application to use /clr and access .net. See earlier comments for the background and ultimate goal.

Thank for taking the time to answer but this was exactly the sort of thing I wanted to avoid, due to time constrants. I think you could do something simpler by re-writing regsvr42 as a c++/.net console application but I don't have time for that either. My current solution involves reading a list of public key tokens from a file - not great but quick. I gave the example of GetFileVersionInfo as an example of the kind of api call I'm looking for only it might be called GetPublicKeyToken if it existed point is it would be win32 API not .net

Not clear what you want to acheive here. Do you want a modal or modeless dialog, why do you want to run a modal dialog on a separate thread?

I wouldn't be using ActiveX or VB6 code if I could help it. Unfortunatitly I can't make a business case for spending a year or 2 porting everything to .net. So we take a steady migration approach and make the best of what we have.

This is correct only on the development machine. Problem we have with this is that we may be working on more than one version at a time so building updates the registry to the last version built.

Oh year, thanks for the code you learn something everyday. +5 for the comment

You can pass function pointer to any function template or not. But not as a template parameter(this should be a type could be a type of function pointer) template parameters being the ones in angle brackets <t1, t2=""> as opposed to function parameters in normal brackets (T1 arg1,T2 arg3)

Not sure what exactly it is you want to do. do you want to write a template class, a template function or something else? You might be better just trying it and then posting the code if there is a problem with it.

You have two options as I see it,

1 Get your C# to register as COM objects then call it from c++ (quite technical at the C++ end and problematic if the c# has user interface.

2 Write all the code in C++ - On the face of it probably the best option.

What is the problem now?

Find out what the value of j is when this exception is thrown

Your must be indexing out of the range of the array. not a vb expert if the array range is either 0 to readText.Length-1 or 1 to readText.Length

Good point didn't notice that, still what said about sizeof stands

Some code would be useful here, I don't clearly unstand you issue

what is your problem?

Also Favor Size or Speed Favor small(/Os)

It is not clear where WCF fits into this, Do you want to get rows from a database, send them over some network/internet then display the results in excel? Or just get rows from a database and display them in excel?

CComQIPtr just manages the release of the interface IPicture. You might want to repost this and give more detail on the IPicture interface

Some people seem to have a problem with your statement of urgentcy. People will answer your query as fast as possible adding urgent does seem to get a lot of people's backs up which is a shame because it is quite an interesting question.

How long does the query take if you do it in SQL on the database? If it takes a long time here the problem is with the database.

Do you have any sample code, it is very hard to help without any idea what your program does?

If it doesn't access a member variable then it should be static. Otherwise it will make maintence difficult e.g. some one in the future may change the function to access a member variable but not notice all the places where it is called without an instance

I agree that in practice NULL is nerely always 0 and nullptr is better if available. I don't like the refering to a pointer as 0 because 0 is a value where as the notion of NULL is no value more appt for a pointer. My main point was always initialise a pointer so you know what value it starts with otherwise you can't predict what value it will start with at runtime.

Am I going mad, if AgentFuntion is not static it will crash as soon as it accesses 'this' none of the other answers seem to agree, what is more a release build in VC6 for certain will contain a random address in baseClass. If the function is static then it would look much clearer like the CBaseClass::AgentFunction

We had problems with the dotnet framework compact edition using around 20mb even with a simple application, it seemed to be allocating the memory upfront to speed up the new command. in a dot net object have all the type information associated with them for use with reflection, maybe that is why your structured approach is paying off.

What OS is you device using?

Is Your timer tick reentrant (called before the last one finished)

Could it be something to do with serialPort1.ReadExisting()?

Thanks this is what I have done, but I was expecting a function to do it, Like in MFC CRect has a CenterPoint() function.

Just realised where I got the notion, in C++ MFG CRect has a CenterPoint function C

What language is it? It looks like a strange mix between c# and c++. If it is c++ then remove the public from the start of the function. If it is c# then why is there an #include and where is the class

Have you got ports C and B connected together then. Are they connected correctly? Do the port settings match?
Perhaps your serBread returns 0 because there is nothing to read.

Have you posted the correct code? I can't see any while loops here

I suggest you do some demo web applications that you can send links to along with your cv. Make a web CV and include it as a link in your standard CV. Do some of the free brainbox tests and include the results on your web CV.

Also add a skill summary clearly visible on the first page of your CV, I did a nice graphicical chart showing all my key skills and the amount of experience I had in each.

Personnally I like to group both private, and public functions into logical regions e.g. all method that deal with a partular control on a form

Have you tried
LightControl^ lighcontrol = (LightControl^)obj;
((ILightControl^)lighcontrol)->Settings();

It might help if you say what the problem with the code is.

Does the guid 27CC4E03-D86D-40B5-96D4-F7EA5B148A0D match the key in the registry?

What is the exception? try going to the debug menu an check break when c++ runtime exceptions are thrown.

Games programming is also very broad. C++/WIN32 with DirectX libraries for game run-time and MFC or .NET for development tools. You can get DirectX for .Net but for performance reasons I don't think many games manufactures use this.
