I have written an application in c# that has a reference to a dll written in c++. I can run the application in debug mode and it works great, but after I build the application, it will not start and gives me the following error, any thoughts on how to resolve this?

You need to at least narrow down whether it is the C# application or the C++ DLL.

Hi, thanks for the response. The event log indicates it is the c++ dll that is causing the error. What else would you like to know?

I have seen that error when you mix 64 and 32 bit platforms. The application and the dll need to agree on their "bitness". Check your build parameters for C# to see the platform selected. If it says "Any", that means that, at runtime, it will pick the architecture best for the machine you are running on. If the dll doesn't match that, you will get this error.

Thank you, I will try that on Monday when I get back to work and reply back with the results.

Hello,

I do not see that option in my Visual Studio Express, would this be the proper instructions on how to do that?

Sorry, I don't use Visual Studio Express. In Visual Studio 1008 Enterprise it's in the Project Properties, Build tab, Platform Target field. There's a setting for both Debug and for Release. Sorry I can't post a screenshot of the relevant screen.

How to get the locale? [SOLVED]

After trying many different settings in VS 2008, I downloaded a different version of the helper dll that I was using and this seems to have fixed the issue. Thank you to the two people that replied.

I'm experimenting with D and I'm trying to make a resource manager much like the C# one.

Now I'm hitting a problem...

How do I know the current user locale? i.e. "en-Au" / "en" ?
I found this function: GetUserDefaultLocaleName

but apparently it's only post vista... what if my program run on XP? what should I do? (I'm trying to write an installer, so I'd like to cater, at least from XP tp 7!)

I found this one too: GetUserDefaultLCID() but what am I to do with a LCID?
Is there a referenc etable I can use?

[EDIT]I just found a big table with the exhaustive list of locale...

A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station....

Have you tried GetLocaleInfo()?

Super Lloyd2-Jun-11 16:59

2-Jun-11 16:59

I haven't. The fact it doesn't seems to work on vista and later where I should use GetLocalInfoEx() is a problem.

But I have an exhaustive dictionary of all LCID and and their code name, much better for me! Wink | ;)

I'm not sure what you mean by this, but GetLocaleInfo() dates all the way back to Windows 2000, whereas GetLocaleInfoEx() works on Vista and newer.

Trouble with C macro '#'

#define MyTemplate( filename ) "D:/Template/MyApp/" # filename

#include MyTemplate( stdafx.h ) // failed to compile

int main()
{
cout << MyTmeplate( stdafx.h ) // ok, print "D:/Template/MyApp/stdafx.h"
}

How to include files in "D:/Template/MyApp/" if I don't copy them to my own project directorie?
solution like the macro doesn't work perhaps #include instruction doesn't accept another '#' in its statement.
Could someone help me, thanks in advance!

I recommend you have a look at Token Concatenation[^]. That explains how to define and use a C macro to concatenate tokens.

Considering you're using stdafx.h, I assume you are using Visual Studio? Why not just add the include directory to Additional Include Directories in the Project Properties dialog, under the C/C++ tab. That way, there's no need for possibly troublesome macro's and makes it easier to maintain.
For other build environments there should be similar options.

I found another trouble, I have to include the D:\template for every individual project. Is it possible to include it like "VC98\include" as an one-time-job ?

In vs2005,

1. Go to Tools->Options
2. Click on projects and solutions tree item
3. Select vc++ directories item
4. Select Include files in drop down window "Show Directories for"
5. Then add your include directory.

I think it will be same in all VS IDE.

Is m_Port a pointer?

kosacid wrote:

Why are you casting an int to a pointer? If m_Port is a global int, you'd need something like:

AfxBeginThread(ServerEXE, (LPVOID) &m_Port, THREAD_PRIORITY_NORMAL);

kosacid wrote:
int host_port = (int)param;

This does not look right. If param is supposed to be treated as a pointer to an int, you'd need:

int host_port = *((int *) param);

int *host_port = (int *) param;

Also, why are you having the secondary thread interact with a UI element? Only the primary thread (the one that owns the UI element) should do that.

it passes the param ok its not that its definitly the print function seems to be
m_Print.SetWindowText(ms_Output);

ms_Output contains say "port = 100" if i set it to 100
seems that m_Print.SetWindowText(ms_Output); cant find the edit box its pointing to 0

No surprise since you are attempting this from a secondary thread.
