visual c++ - glDrawElements flicker and crash -

-

I am getting a glitch error while using glDrawElements () I have to simplify the line of text to simplify primitives (Mainly rectangles), but when I call glDrawElements (), the whole screen blinks black for one frame (not just my window area), the next limit is the first Returns to "Windows colors" as well and so it's something from Flicker for the message ends in the message box box 

  NVIDIA OpenGL driver encountered an unreadable error and should close this application Error 12

Is there a setting for GL that I need to reset before calling glDrawElements ()? I know that this is not something glEnableClientState (), I checked it (I was one of those, but then crashing instead of glDrawElements ())

Come to think about it, it looks almost like some back buffer error ... Any ideas to try?

Obviously you are mixing VBO mode and VA mode. It is completely possible but should be used with care.

When you call: 

  glBindBuffer (GL_ARRAY_BUFFER, 0); Glubbind Buffer (GL_ELEMENT_ARRAY_BUFFER, 0);

This means that the next time you render something with glDrawElements (..., ..., ..., x) , then This will use as the pointer on index data, and last call for glVertexPointer points on cholera data.

If you do not no current VBO and IBO (two globalbuff calls given above), this means that when rendering with similar glDrawElements, Strong> In the IBO index data will be used as offset, and glVertexPointer as the offset on the virtual data in last call VBO

Depending on the values ​​of x and glVertexPointer, you can create driver crashes because the offset exceeds the limit and / or the underlying data is of the wrong type (NaN).

/ li>

  • Specify the address on the right with glVertexPointer
  • glDrawElements

    • with correct index address Specify and then it will be fine.

    c# - How to capture HTTP packet with SharpPcap -

    -
    I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...
