I have a MFC SDI application created and added CDialogBar to set as main toolbar as you look in the screenshot I attached. It works well on every windows os(Xp, 7, 8, 8.1, 10) of windows tablet devices except only Microsoft Surface.
Please look at this screenshot. the CDialogBar menu is cut off. I don't know reason why this happens. The drawing issue always only occurs on Microsoft Surface 3 which has high resolution and high DPI screen and it works good on any other tablet. This is very strange issue so I dragged toolbar(CDialogBar) and dropped down on any place then the toolbar was re-painted clearly. So.. through this issue, I am sure that this is re-drawing issue. Is there any drawing function to redraw that area?
I am attaching my minimized source code to represent drawing issue.
Operating System: Windows 10
Tablet: Microsoft Surface 3
Tool: Visual Studio 2015 Update 3
DPI rate: 150%
To resolve this issue, I have been trying to set DPI Awareness property to None, but the graphics Interface was not good and they were all stretched. I really don't like this solution, I have to find other solution without setting DPI Awareness to "None".
hmm, beg to differ in my interpretation of the purpose of this area. I marked it as Type: 'News' and this is listed as the Managed C++/CLI discussion area. That may explain a general lack of actual discussion however. I may post there too. Thanks
interior_ptr<T> is useful if you need pointer arithmetic in managed code or a pointer that can reference a managed or native object. It doesn't pin the referenced object and instead gets updated by the CLR when the object moves just like a handle. Can be useful for some functions that can operate on managed and native objects as a native pointer can be passed to an interior_ptr<T> argument.
pin_ptr<T> is useful if you want a managed object that can be referenced by native code. It stops the GC from moving the object so the object's address can be safely assigned to a native pointer as long as the pin_ptr<T> is alive. You see this used a lot when people manually marshal System::String to a char*.
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 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)
