it is a bit easy task to load an image, on a dialog
but before i proceed to suggest you the best technique, that suits your application,
please answer these questions.
1.is your image constant throughout the application, or it may change based on the context dynamically.
2.have you already created a resource for that image?
3.if you have only one image and want to see it on the screen, then you can link it statically.
4.if you have to load images, based on the context(condition) then you can take that many number of controls and toggle them as per your requirement.

I have to change the image dynamically according to the move movement on the dialog box
S.Yamini
|
|
|
|
|
how many images you have to the max.
|
|
|
|
|
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
|
|
|
|
|
assign a member variable to that control,
then, m_ctrl.GetDC();
|
|
|
|
|
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.
|
|
|
|
|
you should use LoadBitmap as
HBITMAP bitmapHandle = LoadBitmap(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_IMAGE));
|
|
|
|
|
Thanks it works can u suggest me some ways for getting the DC. I have added the code before.
S.Yamini
|
|
|
|
|
You should use
CPaintDC dc(this);
dc.TextOut(...);
if u are intended to use this function in OnPaint() method, otherwise u should use
CClientDC dc(this);
dc.TextOut(...);
|
|
|
|
|
I tried CClientDC but it did not work.Should i have to change any property of the dialog box
S.Yamini
|
|
|
|
|
If u want it use it with CDC(though not recommended) u can use it like below,
PAINTSTRUCT pStruct;
CDC* pDC = BeginPaint(&pStruct);
//Use CDC here.
pDC->DoWhatEverYouWantToDo(); // !!
EndPaint(&pStruct); //Don't forget this o'wise sometime result would be disastrous.!!
(For your knowledge, CClientDC and CPaintDC both do BeginPaint in Constructor and EndPaint in Destructor..)

I tried it in onintidialog it does not work. Can u suggest some more ways to solve this issue
S.Yamini
|
|
|
|
|
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 cannot use erasebk bcoz i have to toggle the images.
S.Yamini
|
|
|
|
|
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 ...
|
|
|
|
|
Yes it will work.
Can u suggest me for transparenting the background for the button control
S.Yamini
|
|
|
|
|
again, You can override OnEraceBk,, and return TRUE from there for that button, it won't paint buton background...
|
|
|
|
|
Thanks I will try
S.Yamini
|
|
|
|
|
If you have bmp on the resource you can use of CBitmap class.
|
|
|
|
|
Thanks.
