Thanks for all help. I got this working. The problem was timing problem in the 3rd party dll's. AppA is starting appB in a sandbox and adds overhead (=> timing problem). Because of this timeing problem a exception was throwed before all dll:s were loaded. (difficult to give a precise explanation of a few short lines here)

Yes but is is still not working. From AppB i print System.IO.Directory.GetCurrentWorkingDirectory() and that path is alright. I Also print all loaded dll:s and when AppB is started through Process:Start, some dlls are not loaded

I have two C# .NET applications, AppA (located in folder A) and AppB (located in folder B). AppB is also using a lot of 3rd party dll:s and configuration files located in folder B. If I start AppB from folder B the application is working as expected. The problem is when I start appB from appA using Process.Start(), and Process.StartInfo.FileName is pointing to appB. AppB is now starting up, but it seems like it is trying to load resources from folder A instead of folder B. How can I solve this? appB shall always load resources and dll:s from folder B.

I am using a app.config to load dll from other folders than my applications bin folder. Now I can load all the dll:s my application need at startup. The problem is that my application is using another dll when the user presses a button. Can I load this dll using the app.config?

Thanks

I have a assembly A that must use .NET framework 3.5. This assembly has a referense to a 3rd party assembly that has been developed with .net framework 4.0. The problem is that I can't build because the 3rd party uses FW 4.0. Is it possible to solve this?

I have a C# application that tests a product my company developes. At the moment this application can be run on a ordinary laptop. I have now started to develope new tests that requires specific hardware and dll:s. These new tests can only be run on a computer that has this hardware installed. What is the best solution if I still want to be able to use the same application on an ordinary laptop to run the other tests that don't requires the new hardware? The "ordinary laptop" is missing the dll:s that my application is using to communicatio with the hardware.

Hi, I have a comma separated text file and I want to get all SerialNumber for a specific device. Example: I want to get the SerialNumber for all Device:A1 => 345 and 347

ID:432,Name:Jones,SerialNumber:345,Device:A1
ID:432,Name:Mark,SerialNumber:347,Device:A1
ID:432,Name:Ann,SerialNumber:346,Device:A2

I have now solved this problem with a combination of linq, foreach and regex. How can I do this in one linq expression? Best regards Olof

Hi, I want to have a fast algorithm to determine if it’s leap year, is this a good one?

bool isLeapYear(int year)
{
bool leapYear = year%4 == 0 && (year %100 != 0 || year%400 == 0;
return leapYear;
}

Thanks!

Hi, In a C++ software projetc I'm working with they gets

number of bytes = ((number of bits)* 7) / 8

Why isn't

number of bytes = (number of bits) / 8

Thanks!

Thanks!!

I have a C++ class that implements a interface (ErrorInterface), because of old design. My class don't uses one of the methods (reset) in this interface but I have added an empty implementation because I don't want the class to be abstract. When I build the project I get warnings "unused parameters 'error'". Can I remove this warning?

//Interface
class ErrorInterface
{
public:
virtual void reset(ErrorType error) = 0;
};

//.cpp file I have just added the implementation
//because I don't want MyClass to be abstract
void MyClass::reset(ErrorType error)
{
}

I use this solution, then it's working.

Yes.

I already include that header file

Hi, I'm working with a C++ project and have created a new .h file that contains typedef of new types. How do I use the new types in another class?

#ifndef COMMONSETTINGS_H_
#define COMMONSETTINGS_H_

typedef enum
{
    XX = 0,
    YY,
    ZZ
} ProductType;

#endif /* COMMONSETTINGS_H_ */

And the class that uses the type ProductType

class TestClass
{
public:
//! Constructor
TestClass();

//! Desctructor
virtual ~TestClass();

private:
ProductType product;
};

How do I do to use ProductTyp in TestClass? Now I get compile erro since TestClass can not find ProductType. What is the best way to solve this? I want to declare new types in a file and use the types in several other classes. /Olof

Hi, I need to get all installed languages on the computer. "Control Panel / Regional and Language / Keyboards and Languages / Display language". How can I get the selected language in .NET? Our application has language settings for a lot of different languages. If our application don't has support for the selected language in "Display language" then we have to see if we has support for a fallback language. I tried to use "GetThreadPreferredUILanguages" call and it work fine when I use C++, but I can't get is working on .NET. Is there an .NET call I can use instead to get selected languages and also the fallback languages? C++ code

wchar\_t buf\[2323\];

wchar\_t \*pBuf;

ULONG numLangs;

ULONG size= 2323;



GetThreadPreferredUILanguages(MUI\_MERGE\_USER\_FALLBACK, &numLangs, buf, &

C# code

[DllImport("Kernel32.dll", CharSet = CharSet.Auto)]

    static extern System.Boolean GetThreadPreferredUILanguages(

        System.UInt32 dwFlags,

        ref System.UInt32 pulNumLanguages,

        **out** System.IntPtr pwszLanguagesBuffer,

        ref System.UInt32 pcchLanguagesBuffer

        );





      uint MUI\_MERGE\_USER\_FALLBACK = 0x20;

        uint numLang = 0;

        IntPtr pwszLangBuf = new IntPtr();

        uint langBuf = 2323;

        bool b = GetThreadPreferredUILanguages(MUI\_MERGE\_USER\_FALLBACK, ref numLang, out pwszLangBuf, ref langBuf);



        string tmp = Marshal.PtrToStringAuto(pwszLangBuf

tmp string variable contains only a lot of chinese characters after Marshal.PtrToStringAuto(pwszLangBuf);. pulNumLanguages and pcchLanguagesBuffer returns the same in both C++ and C#. See more information about GetThreadPreferredUILanguages on http://msdn.microsoft.com/en-us/library/dd318128(v=vs.85).aspx[^] What is wrong? Regards Olof

I was just wondering if anyone could see something wrong with my C# struct declaration that could cause this error. Maybe, I shall see if I can get hold of the people who created this dll.

Yes, fnMGetApnData() is the unmanaged call to the dll. I don't have the source code to this dll. I tried to debug this unmanaged call in the assembler code but have not enought assembler experience. The only thing I can see is that a assembler "call" is causing the exception.

Hi, I am calling a .dll from C#. There is no problem loading the dll and call some functions from C#, but one function call gives "System.AccessViolationExceptionMessage: Attempted to read or write protected memory. This is often an indication that other memory is corrupt." There is no problem to call this function from c++. I suppose something is wrong with the structures I use in C# but I'm not sure what and how to solve this issue.

Of cours not, are you stupid or??? It very difficult to know when the user puts the system into sleep. And I don't see the meaning of your comment, you have no idea how big our application is and how it work. The application stops working ~1/100 sleep resume tests. Thanks for your answer!
