Question: I am developing an **OpenG**L application and need to use the **glew** library. I am using **Visual Studio C++ 2008 Express**.

I compiled a program using gl.h, glu.h, and glut.h just fine and it does what it's supposed to do. But after including glew.h it still compiles just fine, but when I try:

```
glewInit();
if (glewIsSupported("GL_VERSION_2_0"))
    printf("Ready for OpenGL 2.0\n");
else {
    printf("OpenGL 2.0 not supported\n");
}

```

It keeps printing:

> 
> "OpenGL 2.0 not supported".
> 
> 
> 

I tried to change it to `glewIsSupported("GL_VERSION_1_3")` or even `glewIsSupported("GL_VERSION_1_0")` and it still returns false meaning that it does not support OpenGL version whatever.

I have a Radeon HD 5750 so, it should support OpenGL 3.1 and some of the features of 3.2. I know that all the device drivers are installed properly since I was able to run all the programs in the Radeon sdk provided by ATI.

I also installed Opengl Extensions Viewer 3.15 and it says OpenGL Version 3.1 Ati Driver 6.14.10.9116. I tired all of them `GLEW_VERSION_1_1`, `GLEW_VERSION_1_2`, `GLEW_VERSION_1_3`, `GLEW_VERSION_2_0`, `GLEW_VERSION_2_1`, `GLEW_VERSION_3_0` and all of these return false.

Any other suggestioms? I even tried `GLEW_ARB_vertex_shader` `&&` `GLEW_ARB_fragment_shader` and this is returning false as well.

Answer: 
there may be some lack of necessary initialization. I encounter the same question. And here is how I solve the question: you need to include the `glCreateWindow()` ahead. Include this function and try again.
I encountered the same problem when running a program through windows **RDP**, then I noticed that my **video card** may not working properly when using RDP, so I tried **teamviewer** instead, both glewinfo.exe and my program start to work normally then. 

The OP's problem may be solved for a long time, just for others' infomation.
