I'm just conducting a research. Is it possible to create a round shape on screen that can be invisible or not seen by human eye,which can be seen by software that perform something like bio-metric reading/face detector. Its can not be only a shape even if its some sort of light/image that is impossible for a human to see but possible to software doing similar as face detection?
If this is possible how could one go about doing this and what this form is called and also if any knows samples, documentation about this.
I know this maybe a complex question but as I've said I'm conducting a research on this.
Hi, thanks. but what I mean is that if it can be something that will not block a user from seeing from the screen. Something like water mark. even if its visible but a user must be able to see through it clearly.
Thanks and this looks as if its exactly what I'm looking for, but what how can I make this be sort of transparent? I mean the whole form with one picture to be sort of transparent so that I can see through it while the picture is not 100% invisible but be a see through?
I want my form to be OnTop always and it must not block me from using a computer, I must be able to see through it with the picture or make it show lets say after 20 seconds and be 100% transparent and after 20 seconds be maybe 99.8% or 99.9% transparent. The transparent must be something which I can also detect by maybe a face detector technique.
I have the following program and I am trying to do the conactenation of two strings using overloading operator "+", but I am getting error in function "String operator+ (String box)" and line "box4 = box1 + box2".
Why doesn't show my string concatenated ?
Using Windows 7 and VS 2010 (soon 2015).
I’m writing a C++ managed code dll (managed.dll)which will be an intermediary between our unmanaged C++ code (program.exe) and a third party C# driver dll (tcbDriver.dll).
I don’t have access to the code for tcbDriver.dll. However, in the following example of managed.dll code, I use a TcbDriver class which accesses the tcbDriver.dll. So program.exe calls "__declspec(dllexport) int ConnectTCB()" in managed.dll, which in turns calls Connect() in tcbDriver.dll.
The problem is, I don’t know how get the managed.dll code to preserve the same instance of "work" or "tcb" for other methods that program.exe will call.
For example, in this case tcbDriver.dll will eventually make tcb.Initialized equal to "true", indicating it is done initializing the hardware.
However, managed.dll needs to use the same instance of "work" or "tcb" in another exposed function that it used to call Connect().
The exposed function "__declspec(dllexport) bool IsInitialized()" makes a new instance, so tcbDriver.dll doesn't ever make tcb.Initialized equal to "true", even after TcbDriver is done initializing.
I have the following code.
Why does not my x is displayed.
I do not understand, X is returned by the getX() function wich is called from the derived class SecondClass() through an object of type FirstClass().
Initialization of X was done using constructor function FirstClass(int x).
I did not want to use the initialization function like setX ().
cout <<"\n Default constructor FirstClass()."<< endl;
cout <<"\n Constructor FirstClass()."<< endl;
this->x = x;
cout <<"\n X = "<< x << endl;
class SecondClass:protected FirstClass
cout <<"\n Constructor SecondClass()."<< endl;
void printX(FirstClass& obj)
cout <<"\n X = "<< obj.getX() << endl;
I am a student of BS(CS) "Computer Science" .
I have a project of "AES Code implementation in C++" and i have submit that project on 28 JUNE 2016
I have a technical issue in my code
Only serious programmers were needed. I can provide any sort of help (to understand my code)
