I am binding JMC objective C static library to Xamarin compatible one, currently I am trying to build my binding project now(which contains ApiDefinition.cs, StructsAndEnums.cs and libJmcSDK.a) but when I try to build this Xamarin binding project I'm getting the following error:
BTOUCH: error BI1017: btouch: Do not know how to make a signature for System.Int32* in method 'get_IssueTransport'.
When I try to search for get_IssueTransport method, their is no search results for this, trying to find the System.Int32 signature as well but not able to find in throughout solution.
Any help in resolving this issue is much appreciated in advance. Thanks.
Answer
Remove unsafe keyword and * from int.
Like:
unsafe int*
Change int* (any pointer type) to IntPtr

I have an multi Module Project. Here we are passing System::Object^ from one exe to code from another DLL.
When I am trying to convert that Object to its type(Here we have the same definition) in DLL, I am getting the below error...
[A] can not be cast to [B]; A originates from one assembly , b from another
I tried through some documents but could not crack through.
Both the below code giving that conversion error
LocalClassType ^x1 = LocalClassType (x);
LocalClassType ^x2 = cli::safe_cast<LocalClassType ^>(x)
Can anyone please suggest or guide me through the document where I can convert correctly.
I was able to resolve the issue, and cast it using static_cast
LocalClassType ^x2 = static_cast<LocalClassType ^>(x)
I want to access the file generated by Xtext to compile it automatically. So I need its absolute path. It's enough to get the absolute path of the current project at run-time. Any idea how I can get it?
I am working inside the "MyDslGenerator" Class. I tried to get it from the "resource" in
override void doGenerate(Resource resource, IFileSystemAccess fsa)
but couldn't find it.
Help is highly appreciated.
I ended up using this code:
var uri = (fsa as IFileSystemAccessExtension2).getURI(fileName)
maybe you can use the Interface org.eclipse.xtext.generator.IFileSystemAccessExtension2. the passed IFileSystemAccess may implement this interface too.
I'm writing a basic program using direct3d and DXUT.
I am creating a direct3d device manually with D3D11CreateDeviceAndSwapChain() and passing it to DXUT using the DXUTSetD3D11Device() function which, according to the documentation should be correct.
What confuses me is that I get an LNK2019: unresolved external symbol error when calling DXUTSetD3D11Device(). I can call other DXUT functions such as DXUTCreateWindow() just fine, also I have built DXUT myself and have linked to it properly.
When I look in DXUT.h I can find the declaration of DXUTSetD3D11Device() but when I look in DXUT.cpp I can't find any reference to this function, so I think this might be why I'm getting this linker error.
This seems to be the same problem as mine.
I'll leave the relevant pieces of code here, just in case:
bool DXUTEngine::Initialise()
{
HR(DXUTCreateWindow(m_appname));
if(!m_pDirect3D->Initialise(DXUTGetHWND(), m_width, m_height))
{
OutputDebugString(L"\n\n Failed to initialise Direct3D\n\n");
return false;
}
HR(DXUTSetD3D11Device(m_pDirect3D->GetDevice(), m_pDirect3D->GetSwapChain()));
return true;
}
Here's where I create the device:
result = D3D11CreateDeviceAndSwapChain(NULL, driverType, NULL, 0, &featureLevel, 1,
D3D11_SDK_VERSION, &swapChainDesc, &m_pSwapChain, &m_pDevice, NULL, &m_pContext);
At the moment I either think I'm doing something very wrong or that this function just doesn't exist. I'd really appreciate any help.
Thanks in advance.
From the link you post which point to MSDN forum, the DXUT11 framework was delivered in source code, so there is no lib files. so the error was not about any link errors.
Another important thing is: function DXUTSetD3D11Device has no implementation in DXUT framework. if you want to use it, you should implement it yourself.
I am investigating Windows 8 Store app development, and am having trouble locating the following members
Type.IsClass
System.ComponentModel.DesignerProperties.IsInDesignTool
Visual studio claims they don't exist, but MSDN suggests they should.
I am obviously missing something silly: Can anyone point me in the right direction please?
Regards
John.
The IsClass property has moved to the TypeInfo class. Basically you need to replace;
bool result = type.IsClass;
with;
bool result = type.GetTypeInfo().IsClass;
GetTypeInfo() is an extension method from the System.Reflection namespace, no not obviously visible on System.Type unless you're already using System.Reflection.
The IsInDesignTool property has moved to another place too and changed name;
bool result = Windows.ApplicationModel.DesignMode.DesignModeEnabled;
Does anyone have the faintest idea what this error means please and how to resolve it? All my research is drawing a blank, I can see how to set it on MSDN but it doesn't explain it in a way that explains to me what the issue is. If I remove some of my LINQ queries to set viewbag items then it seems to resolve it but the moment I set new ones and pass them into my view to generate a mail for MVCMailer it comes back. Not sure if its a viewbag issue or simply that I am calling too many linq queries to generate them to pass to the view.
I am very stuck (again)..........
Cheers,
Steve.
DbLimitExpression requires a collection argument.

An example of the code is:
var VBSalutation = from A in context.Salutations
where A.SalutationId == policytransaction.SalutationId
select A.SalutationName;
ViewBag.Salutation = VBSalutation.FirstOrDefault();
This is repeated for various parameters and then passed to the view.
Well, I faced a similar problem and solved it. Problem was in WHERE clause: data type of left side equal operator (=) sign was not matching with data type of right side. So in your scenario:
where A.SalutationId == policytransaction.SalutationId
SalutationID of A might be an INT and SalutationId of policytransaction might be a string (This is how it was in my case).
I solved it by assigning policytransaction.SalutationId to an Int variable and using it:
int myIntVariable = Convert.ToInt16(policytransaction.SalutationId);
...//some code here
where A.SalutationId == myIntVariable;
Please also note that you cannot directly cast your variables directly in Linq else you'll get an error "LINQ to Entities does not recognize the method". You'll have to use a temp variable and then apply the where clause.
Try ViewBag.Salutation = VBSalutation.SingleOrDefault();
