Could someone explain in pseudo code what this line is doing?

hr = pEnumerator->RegisterEndpointNotificationCallback((IMMNotificationClient*)&pNotify1);

Specifically this part:...

Does anyone have a working example of this http://msdn.microsoft.com/en-us/library/windows/desktop/dd371417(v=vs.85).aspx

I've tried the code posted here...

Thank you... you C++ guys are amazing!!

This works perfectly for me, and should be enough to get me on my way.
(I'm sure I'll hit a few stumbling blocks, and might have to ask more questions).

Yes, I had read that, but still being fairly new to C++ I find this very confusing.

Can one type be cast to another then?

I have been using GDI+ in my VB6 projects for the last year, and have...

So are you are saying the Flat Api functions cannot be used in C++,
or just that using the wrapper method is easier?

I added

using namespace Gdiplus:: DllExports;

to my code and I now get...

I am trying to figure out how to call a GDI+ Flat Api function, but cannot get anything working.

Here is my code:


#include <windows.h>
#include <objidl.h>
#include <gdiplus.h>
#include...

I for some reason didn't think you could mix GDI and GDI+

Curiosity then, this cannot be done using GDI+ alone?

I cannot find how to draw a simple selection rectangle (rubberband) using
GDI+.

This should be a simple thing, but I'm beginning to wonder if it is even possible.

If I set the last parameter of the GdipDrawImageRectRect function to UnitInch I get a Not Implemented error

If I do as below I get proper drawing except not to the specified dimension (want 1" X...

Thanks for the suggestion.

I tried that; I get an error when GdipDrawImageRectRect executes
(and obviously nothing gets drawn).

I am trying to draw a bitmap on the screen 1" X 1.5" using this code:



status = GdipDrawImageRectRect(graphics, image, _
0, 0, 1, 1.5 , _
...

OK, I tried your code and it works perfectly to rotate the image about the center.

It draws the rotating bitmap with top left corner at (0, 0) on my form.

I tried moving the top left corner of...

Thanks Chris_F

I think I understand what you are saying.

I will try later and see if it works for me like I think it should.

I am trying to rotate a bitmap about it's center point.
The bitmap I am using in my test project is 200 X 200 pixels.

By trial and error, I came up with the following. It works, but I don't...

Yes I used delete with the new method of declaration...
don't know if I used it correctly, but there were no compile errors or warnings.

Yes I've seen that Hello World program before.

Thanks ovidiucucu, both of your methods work... code successfully produces a metafile. :D

While we are on the subject of new, when might it be necessary to declare something this way?

Also, I...

I am trying to use GDI+ to create the metafile (file that contains all instructions to render a vector image).

The following line of code won't compile (I copied it from MSDN)
myMetafile = new Metafile(L"MyDiskFile.emf", hdc);

I get this error:
error C2065 'myMetafile' : undeclared identifier

I've...

Changing the specifier in fprintf works with your suggestion... Thanks!



FILE *fp2;
fp2 = fopen("output2.txt", "w");
fprintf(fp2, "dwBytesRecorded = %d\n", lpBuffer[0].dwBytesRecorded);
...

Thanks for offering some help.

Still not getting the results I expect.

fprintf(fp, "[%d] <%s>\n", j, lpBuffer[0].lpData);
returns
[0] <>
[1] <>
[2] <>
[3] <>

I am trying to print the contents of a buffer LPMIDIHDR lpBuffer

I am after the lpData member, and since it is declared as LPSTR

I tried doing it this way:


fprintf(fp,"lpBuffer =...

I should add, the program operates properly for both type 0 and type 1 MIDI files,
it is just my printing code that causes problems.

I am making progress with printing to a file, but have run into a problem that I don't understand.

I am trying to read a MIDI file and print out the contents.

The code below works for standard...

Works perfect!

I coudn't get the cout to work, but I did it with fprintf.

Thanks!

With regards to the code/output in Post #11, I would like output as so:


lpEvent->nData = 8
lpEvent->lpData = <untitled««««««««>
char 1 = u = hex = 75
char 2 = n = hex = 6E
