If the window you want to refresh was created by you, then you can take the handle of that window, and refresh it using RedrawWindow(); Like: m_pEnhancedWindow->RedrawWindow();//where m_pEnhancedWindow is the pointer to that window. I don't know how you are using the window. I mean if you have its handle, pointer etc. If this does not solve the problem then a little code would help. this is this.

Use the ON_COMMAND message map to perform the specific operation on the toolbar button.

First, you need to get the dimensions of the bitmaps, then allocate an appropriate array (wid*hei*bpp/8 bytes). Use the GetBitmapBits function to populate the array. Do the same with the second array. Subtract them byte by byte. Use the SetBitmapBits to fill the CBitmap. Live long and in prosper johny74656@gmail.com

If you use GDI+, you can use the Bitmap constructor that takes a path. You can draw the image yourself, or you can use a PictureBox control. If you're in VC6 and don't want GDI+, then ::LoadImage will load a bitmap file, which you can then do the same with. There is no support for other image formats in VC6 without GDI+, or some other library such as Paintlib. Christian Graus - Microsoft MVP - C++
