I have two projects in my solution:
1. Project1, containing camera code which captures image frames
2. Project2, which takes input image and does processing on it. I would like to share/provide the image generated in project1 to the project2. I am trying to use Project references to share data between projects.
I created a class(with namespace) containing the required data members(to be shared) and member functions(populating the data members) in Project1. I am not able to use this class in Project2 despite adding Project Reference in Project2.
Project1:
namespace TheImagingSource
{
class Images {
public:
UINT8 input_image1[IMAGE_SIZE];
UINT8 input_image2[IMAGE_SIZE];
void upload_image(Mat);
} TIS;
void Images::upload_image(Mat m)
{
memcpy(input_image1, m.data, IMAGE_SIZE);
memcpy(input_image2, m.data, IMAGE_SIZE);
}
}
The 'using Project1' statement in Project2 gives error: identifier 'Project1' is undefined.

I want to delete all the object that is not used now.
I used Visual Studio 2019.
When I search Object Browser, It gets to me some strange struct or class that I modified of name.
For example, first I define a structure as
typedef struct stOutput
{
double dDirtyPrice_CumInt;
double dDM;
//...
double dYield;
} stOutput
Later I changed this definition to
typedef struct stOutput_New
{
double dAI;
//...
long lObservStartDate;
} stOutput_New
However, the object browser shows to me just
stOutput.
There is no stOutput_New.
Also I put my cursor on 'stOutput_New' and push 'F12' then it locates my view some strange area.
There are even no 'stOutput_New'
Now, below picture is describing my real situation
This is 'Class View'
Actually I just use One stOutput, but there are so many stOutput that has same file path
Also below picture is my 'Object Browser'
As you can see the two stOutput have different member variables.
And I changed the name from stOutput to stOutput_new the latter.
But it seems my object browser didn't reflect it.
I tried
Project Unload and Reload it
Organize the code of Solution and Project
Re-Build Solution.
But everything doesn't work.
Please help me
In vs2019, I defined the structure exactly like yours according to your description, and then changed the structure according to your description. My object browser did not have the problem you described. If you are sure that your code does not repeat the definition of structure and other problems, I suggest you reinstall or repair VS.

I have two files in a Unity3d project. One is a test script that runs in edit mode. The other is a single class with static functions that I'd like to call from the test scripts.
here's my test script:
using UnityEngine;
using UnityEngine.TestTools;
using NUnit.Framework;
using System.Collections;
public class NewTestScript
{
[Test]
public void TestAnotherStaticFunction()
{
int a = NewBehaviourScript.FunctionUnderTest(1);
int b = 1;
// Use the Assert class to test conditions.
Assert.IsTrue(a == b);
}
}
here's my function under test:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class NewBehaviourScript : MonoBehaviour
{
/// <summary>
/// the stupidest function in the world,
/// used to verify tests.
/// </summary>
public static int FunctionUnderTest(int a)
{
return a;
}
}
This gives me the error from the Unity compiler (I'm not building outside of Unity):
Assets/TestS/NewTestScript.cs(12,17): error CS0103: The name `NewBehaviourScript' does not exist in the current context
These are running in edit-mode.
I've tried adding and removing the SuperTestNameSpace namespace from the function under test and the calling code.
I've attempted adding/removing files from the .asmdef file that was autogenerated by unity, although this usually leads to other compile errors.
My previous unit test experience is largely in Visual Studio or VSCode, and I'm trying to get my unity3d test experience to match my prior test environment experiences.
Is there a fundamentally limited functionality in the edit-mode tests, or am I missing something stupid?
Further elaboration on the assemblies involved. It looks like there are two assemblies at play here: Assembly-CSharp.dll contains my code under test and TestS.dll contains my testing code. I believe my questions boils down to: how do I add a reference from the TestS.dll assembly to the Assembly-CSharp.dll. I'd know how to do this in Visual Studio (either via the context menu in VS or directly editing the csproj file), however I don't see how to do it in Unity3d. Any edit I make to the csproj file is frequently overwritten by unity, and while there is a 'references' section in the inspector (see picture) I can't add Assembly-CSharp.dll as a reference.
These are the inspector settings for TestS.asmdef. While there's an option to add references, I can't add a reference to Assembly-CSharp.dll, which is where my code-under-test lives.
Ok, I figured this out. There were two things going on:
Editor tests need to be underneath a folder called editor. It's really annoying that the unity editor doesn't do this for you.
You need to have an assembly definition for the code under test and add a reference from the test code to the newly created assembly definition. This must be done in the Unity editor UI.
by default, unity adds your script code to an assembly called Assembly-CSharp.dll, and, for reasons unknown, this assembly isn't referenced by my edit mode test code. I'm not sure if this is a bug in Unity or if it's by design, but explicitly creating and referencing the assembly definition has cleared things up.
The main issue is currently you are trying to call the
NewBehaviourScript(1);
constructor which does not exist...
instead of the method
using SuperTestNameSpace;
//...
NewBehaviourScript.FunctionUnderTest(1);
or alternatively with the namespace in the call directly
SuperTestNameSpace.NewBehaviourScript.FunctionUnderTest(1);
Also make sure the filename matches exactly the class name. So in your case it should be
NewBehaviourScript.cs
Note that the .cs is not printed by Unity in the Project view so there it should say NewBehaviourScript.
Why does it not compile with the using SuperTestNameSpace;? What is the error?
If that exception
Assets/TestS/NewTestScript.cs(14,17): error CS0103: The name `NewBehaviourScript' does not exist in the current context
is only shown in VisualStudio but the script compiling fine in Unity especially after adding a new script it helps to simply close and restart VS.
In some cases it also helps to close Unity and VS, remove all files and folders except Assets and ProjectSettings (and if you are under version control anything that belongs to it like e.g. .git, .gitignore, .gitattributes etc) in particular delete the Library, .vs folder and all .csproj and .sln files.
Than open Unity again and let it recompile everything.
Make sure the file that contains your NewBehaviourScript class IS NOT inside an Editor folder.
Move both the scripts in the Assets (root) folder and try again.
I'm just beginning to write code with C++, and I got stuck when I want to add reference to class from other project from the same solutions.
my Main code located at :
InventoryAppDLL (contains code to access Sql Database)
class : dbConnection.h
Code:
ref class dbConnection
{
public:
dbConnection();
void SetCommandText(String ^command,bool ^commandText);
int ExecuteScalar();
DataSet^ ExecuteDataSet();
DataTable^ ExecuteDataTable();
protected:
~dbConnection();
private:
DbConnection ^conn;
DbCommand ^cmd;
ConnectionStringSettings ^settings;
DbProviderFactory ^fac;
};
after i build the main project (InventoryAppDLL), it was success and contains no errors.
but after I include the header into another project (InventoryAppService),and then I build it, it contains error :
error C2143: syntax error : missing ';' before '^'
when I reference to the error, I've got ConnectionStringSettings missing library on dbConnectionClass (InventoryAppDLL).
private:
DbConnection ^conn;
DbCommand ^cmd;
ConnectionStringSettings ^settings; // <---
DbProviderFactory ^fac;
};
I think you don't even need to include the header file. Since you have already added a reference from the consuming project to the project containing this class, the consuming project can read the metadata from the DLL project and you can simply say:
auto x = ref new dbConnection();
I have a Visual C++ solution, which consists out of 3 projects.
One of these projects, project "A" is used by both other projects and it has some global data which should always be the same.
However when I link project A into both other projects it seems that two instances of project A are working on different data.
Can this be the case and how can I set up the linking process to prevent this from happending?
--- Update to make things more clear
- Project 1 -
main () {
init();
test();
}
- Project 2 -
test () {
cout << get_data();
}
- Project A -
int data;
init() {
data = 123;
}
get_data() {
return data;
}
As you can see in this exaple I am initializeing the data of project A in the first project and I am accessing it from the second project. My observation is that the data is not initialized when the acces from the second project takes place.
Both projects A and 2 are linked statically into project 1 so the output is a single executable.
A global resides in a single place in a process's memory space. If you have two processes that share a module, they'll each have separate variable, yes.
You'll need to use IPC to share data between processes.
The symbols from project A in the static library are linked into both project 1 and project 2, separately. Getting them merged involves compiler-specific mechanisms.
Basically, you must make project 2 re-export project A's symbols, and have project 1 import those instead of importing project A directly.
If you can't do that (e.g. because you don't have control over either project 1 or 2), you must write workarounds inside project A. One option (the easiest usually) is to convert project A to a dynamic library. Then both project 1 and 2 load the same instance of project A and the data is shared.
Another option is to change project A so that it doesn't have a global variable, but instead registers a process-global data item that contains the data you want; for example, you could abuse the local atom table[1] to store a pointer to dynamic memory.

I followed the instructions I found in form of tessesract on how to includ baseapi.h.
i am using:
vs2010
Version tesseract 3.01
i try to understand how to use baseapi.h.
test program:
#define __MSW32__
#include "baseapi.h"
using namespace tesseract;
int _tmain(int argc, _TCHAR* argv[])
{
TessBaseAPI *myTestApi;
myTestApi=new TessBaseAPI();
//myTestApi->Init("d:/temp.jpg","eng");
return 0;
}
form gide:
add the following folders to Additional Include Directories (properties) - to resolve file not found issues after including "baseapi.h"
tesseract-3.01/api
tesseract-3.01/ccmain
tesseract-3.01/ccutil
tesseract-3.01/ccstruct
added the following libs to "Properties/Linker/Input/Additional Dependancies" in order to use the Tesseract and Leptonica libs libtesseract.lib;liblept.lib
// added the following paths to "Properties/Linker/General/Additional Library Directories" in order to find the Tesseract and Leptonica libs
tesseract-3.01/vs2010/Release
tesseract-3.01/vs2008/lib
And I try to run now
So I try to find libs libtesseract.lib and replaced with libtesseract_tessopt.lib and then run
1>------ Build started: Project: test4, Configuration: Debug Win32 ------
1> test4.cpp
1>test4.obj : error LNK2019: unresolved external symbol "public: __thiscall tesseract::TessBaseAPI::TessBaseAPI(void)" (??0TessBaseAPI#tesseract##QAE#XZ) referenced in function _wmain

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
Is anything known solution to the problem?

This is what I did to compile it:
1.) Copy all header files into one includedirectory, so later only §(TESS_DIR)\include has to be added to the include directories.
copy the leptonica headers into $(TESS_DIR)\include\leptonica.
2.) Open vs2010\tesseract.sln and compile all configurations. Then copy all lib files into $(TESS_DIR)\lib\debug and $(TESS_DIR)\lib\release. Then add those directories to the build settings.
3.) Copy the compiled libtesseract.dll and liblept168.dll as well as the folder tessdata, containg eng.traineddata, to the Release folder of your project.
4.) Add these libraries as additional dependencies:
libtesseract.lib
liblept168.lib
5.) #include <baseapi.h>
I figured it out, if you are using visual studios 2010 and are using windows forms / designer you can add it easily this way with no issues
1) add the following projects to your project ( i am warning you once, do not add the tesseract solution, or change any setting in the projects you add, unless you love to hate yourself )
ccmain
ccstruct
ccutil
classify
cube
cutil
dict
image
libtesseract
nutral_networks
textord
viewer
wordrec
you can add the others but you don’t really want all that built into your project do you? naaa, build those separately
2) go to your project properties and add libtesseract as a reference, you can now that it is visible as a project, this will make it so that your project builds fast without examining the millions of warnings within tesseract. [common properties]->[add reference]
3) right click your project in the solution explorer and click project dependencies, make sure it is dependant on libtesseract or even all of them, it just means they build before your project.
4) the tesseract 2010 visual studio projects contain a number of configuration settings aka release, release.dll, debug, debug.dll, it seems that the release.dll settings produce the right files. First, set the solution output to release.dll. Click your project properties. Then click configuration manager. If that is not available, do this, click the SOLUTION's properties in the solution tree and click configuration tab, you will see a list of projects and the associated configuration settings. You will notice your project is not set to release.dll even though the output is. If you took the second route you still need to click configuration manager. Then you can edit the settings, click new on your projects settings and call it release.dll...exactly the same as the rest of them and copy the settings from release. Do the same thing for Debug, so that you have a debug.dll name copied from debug settings. wheew...almost done
5) Don’t try to change tesseracts settings to match yours....that wont work ....and when the new release comes out you wont be able to just "throw it in" and go. Accept the fact that in this state your new modes are Release.dll and Debug.dll. don’t stress out...you can go back when its is finished and remove the projects from your solution.
6) Guess where the libraries and dll’s come out? in your project, you may or may not need to add the library directories. Some people say to dump all the headers into a single folder so they only need to add one folder to the includes but not me. I want to be able to delete the tesseract folder and reload it from the zips without extra work....and be fully ready to update in one move or restore it if I made a mess of the code. Its a bit of work and you can to it with code instead of the settings which is the way i do it, but you should include all the folders that contain header files within the 2010 tesseract project folder and leave them alone.
7) there is no need to add any files to your project. just these lines of code..... I have included some additional code that converts from one foreign data set to the tiff friendly version with no need to save / load file. aren’t I nice?
8) now you can fully debug in debug.dll and release.dll, once you have successfully built it into your project even once you can remove all the added projects and it will be peeerfect. no extra compiling or errors. fully debugable, all natural.
9) If I remember right, I could not get around the fact I had to copy the files in 2008/lib/ into my projects release folder….darn it.
In my projects “functions.h” I put
#pragma comment (lib, "liblept.lib" )
#define _USE_TESSERACT_
#ifdef _USE_TESSERACT_
#pragma comment (lib, "libtesseract.lib" )
#include <baseapi.h>
#endif
#include <allheaders.h>
in my main project I put this in a class as a member:
tesseract::TessBaseAPI *readSomeNombers;
and of course I included “functions.h” somewhere
then I put this in my classes constructor:
readSomeNombers = new tesseract::TessBaseAPI();
readSomeNombers ->Init(NULL, "eng" );
readSomeNombers ->SetVariable( "tessedit_char_whitelist", "0123456789,." );
then I created this class member function: and a class member to serve as an output, don’t hate, I don’t like returning variables. Not my style. The memory for the pix does not need to be destroyed when used inside a member function this way I believe and my test suggest this is a safe way to call these functions. But by all means, you can do whatever.
void Gaara::scanTheSpot()
{
Pix *someNewPix;
char* outText;
ostringstream tempStream;
RECT tempRect;
someNewPix = pixCreate( 200 , 40 , 32 );
convertEasyBmpToPix( &scanImage, someNewPix, 87, 42 );
readSomeNombers ->SetImage(someNewPix);
outText = readSomeNombers ->GetUTF8Text();
tempStream.str("");
tempStream << outText;
classMemeberVariable = tempStream.str();
//pixWrite( "test.bmp", someNewPix, IFF_BMP );
}
The object that has the information that I want to scan is in memory and is pointed to by &scanImage. It is from the “EasyBMP” library but that is not important.
Which I deal with in a function in “functions.h”/ “functions.cpp” by the way, i am doing a little extra processing here while i am in the loop, namely thinning the characters and making it black and white and reversing black and white which is unnessesry. At this phase in my development I am still looking for ways to improve the recognition. Though for my proposes this has not yielded bad data yet. My view is to use the default Tess data for simplicity. I am acting heuristically to solve a very complex problem.
void convertEasyBmpToPix( BMP *sourceImage, PIX *outputImage, unsigned startX, unsigned startY )
{
int endX = startX + ( pixGetWidth( outputImage ) );
int endY = startY + ( pixGetHeight( outputImage ) );
unsigned destinationX;
unsigned destinationY = 0;
for( int yLoop = startY; yLoop < endY; yLoop++ )
{
destinationX = 0;
for( int xLoop = startX; xLoop < endX; xLoop++ )
{
if( isWhite( &( sourceImage->GetPixel( xLoop, yLoop ) ) ) )
{
pixSetRGBPixel( outputImage, destinationX, destinationY, 0,0,0 );
}
else
{
pixSetRGBPixel( outputImage, destinationX, destinationY, 255,255,255 );
}
destinationX++;
}
destinationY++;
}
}
bool isWhite( RGBApixel *image )
{
if(
//destination->SetPixel( x, y, source->GetPixel( xLoop, yLoop ) );
( image->Red < 50 ) ||
( image->Blue < 50 ) ||
( image->Green < 50 )
)
{
return false;
}
else
{
return true;
}
}
one thing i dont like is the way I declare the size of the pix outside the function. It seems if I try to do it within the function I have unexpected results....if the memory is alocated while inside it is destroed when I leave.
g m a i l Certainly not my most elegant work but I also gutted the hell out of it for simplicity. Why I bother to share this I don't know. I should have kept it to myself. What is my name? Kage.Sabaku.No.Gaara
before i let you go i should mention the subtle differences between my windows form app and the default settings. namely i use "multi-byte" character set. project properties...and such..give a dog a bone, maybe a vote?
p.p.s. I hate to say it but I made one change to host.c if you use 64 bit you can do the same. Otherwise your on your own.....but my reason was a bit insane you dont have to, kinda silly actually
