Your size parameter values need to be scaled for output to a printer. When drawing to the screen 300 is the number of pixels, but when drawing to a printer it is the number of dots. See SetMapMode function (Windows)[^].
My application don't want to create any entry in registry. If I comment SetRegistryKey(_T("Local AppWizard-Generated Applications")) then application throw an Assert failure. How to overcome from this problem.
I have a MFC dialog application in which I have a gdiplus object that I use to draw images in real-time. Works fine if I don't want to do any changes to this object or its associated variables. But when I try to update them at runtime, it starts to increase my memory consumption.
So, my question is, how to safely update a gdiplus object at runtime.
So whenever the user clicks a button to change between grayscale and color pallette, SetImageColor() is called. When I monitor the memory usage while clicking that button, I see its changing the way I expect it to, but the memory usage keeps increasing at a rate of ~300KB per click.
Is there any safer way to achieve what I am trying to do without memory leaks?
When I am trying run program, command line for ubuntu generation error that.
I'm trying run compline program with command /build/LSB/LSB$ ./thanhtmLSBext Girl.emb.bmp
This is code of my:
File c: thanhtmLSBext.c
int *alloc_int_1D(int rows);
void free_int_1D(int *array);
int main(int argc, char** argv)
int i, j, n = 0;
Mine is a project in Visual C++, in which I am using STL, and trying to use the "find" algorithm with vectors. But it's giving me the error, error C2678: binary '==' : no operator found which takes a left-hand operand of type 'xyz' (or there is no acceptable conversion), because I have an app class in MFC which has a structure 'xyz' whose only member is a BYTE array. I am trying to get the iterator position by finding a value in a vector of a user-defined type and in return I am getting the above error. Hence a problem. Please help.
someone can also suggest, which algorithm should I use to get the iterator position of the value I am searching for,from a vector of a user-defined data type (you can suggest that algorithm from the boost library also)?
Thanks in advance. This is urgent.
Here is the relevant code snippet to understand the problem:
In the header,
typedef struct xyz
class CMyApp : public CWinApp
Many thanks for this solution, I fully appreciate it. Coincidentally, I had already implemented this, but since this was taking time in checking a database which is huge in size, I was looking for some other algorithm which will give a quicker result. Could you please suggest a better algorithm which will save me from using memcmp?
First of all, many thanks for your solution. Although it has solved my operator == overloading question, but I have one more difficulty, may be a strange experience. The find algorithm of STL is not giving the iterator position, even if the item to be searched is located in the BYTE array. Does it have anything to do with the size of the arrays as well? because one BYTE array is of 16 bytes, and the one it is to be compared with is of 33 bytes? In such a case, how can I make the find algorithm give me the correct answer? Please help.
Thanks in advance.
