I have one class derived from ContentControl.
And inside it's content I have ImageSource and a TextBlock, I want to bind the Text property of TextBlock to the Name proeprty of an object but it's not working.Below is the code snippet:
public void AddBitmapToCanvas(System.Drawing.Bitmap bitmap, string pageName,int width,int height,HorizonPage hpage)
I can get data from SQL to datagridview, textbox and combobox objects.
I can edit or view any data from or to database with the above objects!!!
But not to StatusStrip, at least not directly!!!
I get the data from sql to other object, and then pass it to statusstrip.
Is there a direct way? like the other object. statusstrip doesn´t has a datasource
Hi, I am very new to C# but I am modifying an image buffer directly within memory, I am scanning along moving the pointer to get the RGB of each pixel, but I need away to jump around the image memory and read the pixels at random rather than just p++ or p--?
byte* p = (byte*)(void*)pBuffer;
for(int y = 0; y < Height; y++)
for(int x = 0; x < Width; x++)
int srcB = p;
int srcG = p;
int srcR = p;
Hi, the problem is I have only used Blitz Basic before and I could jump to a pixel, eg GetColor(129,280)"Width,Height", with pointers I have to scan along the image for the data, I dont know how to jump to the pixel data I want?
For a 24 bit bitmap, the location of a pixel can be calculated with:
scan0 + y * scan + x * 3
(Note that for a bitmap that is stored upside down, which is the common way, scan0 points to the last line, and scan is a negative value.)
Your code for looping the image is incomplete. The lines might not be stored end-to-end in memory, you have to skip any extra bytes between the lines (calculated by scan - x * 3). Also, if the bitmap is stored upside down, you will either get the data upside down, or only getting garbage after the first line read.
Despite everything, the person most likely to be fooling you next is yourself.
when the last reference to an object (such as a byte array) is given up, the object becomes collectable.
byte myArray=new byte;
myArray=new byte; // old array is abandoned
myArray=null; // second array is abandoned
} // third array is abandoned (myArray out of scope)
Collectable means the garbage collector, when it decides to run, would find and collect the object.
However it will only run when there is a need to run, unless you force it with one of the GC
methods. Doing so is almost always a bad idea, since a GC run is costly, and temporarily blocks all
the threads; therefore the GC should only run when necessary, i.e. when there isn't enough
free memory to satisfy a new SomeThing() request.
