How to use LoadBitmap in a dialog box

[chandu004]

how many images you have to the max.

[Bhavesh Bagadiya]

after onInitdialog completes, whole dialog being repainted so your graphics erased. one solution is to override OnEraseBkgnd and return TRUE from it so System will never erase background. but be careful, system never erase Background !!

I have two images.I has to toggle according to the mouse movement. I nned to know how to get the dc of the dialog control.Please S.Yamini

[yaminisridaran]

I cannot use erasebk bcoz i have to toggle the images. S.Yamini

[Bhavesh Bagadiya]

so whats problem will be in toggling images after overriding eraseBk ??? whatever painting done by you will be there, only system won't paint its default bkground ...

[chandu004]

are you using the bitmap control you have in your tool bar, or is it ok for you if i give my active X control which can take any bitmap image any time. what all you have to do is, you have to specify the file path. for example, ctrl.SetImage("C:\\image1.bmp"); then after some time, ctrl.SetImage("C:\\image2.bmp"); is it ok for u.

[chandu004]

assign a member variable to that control, then, m_ctrl.GetDC();

[yaminisridaran]

Yes it will work. Can u suggest me for transparenting the background for the button control S.Yamini

[Bhavesh Bagadiya]

again, You can override OnEraceBk,, and return TRUE from there for that button, it won't paint buton background...

[yaminisridaran]
