scrollbar in my MFC ActiveX Control

Possibly the debug build defines the _UNICODE symbol while the release build NOT defines it.

Hi,

I want to display a scrollbar in my MFC ActiveX Control. How do i do this? Do i have to create a scrollbar control or is there a way i can specify a scrolling window style or maybe a scrollable view i can work with?

Thanks for the help

Why dont you create a stitched bitmap first and then draw this bitmap on device context.<br />
i mean <br />
Graphics gr(bmpTemp)<br />
.... Stitching code.<br />
<br />
Graphics gr(hDC)<br />
RatateTransform()...<br />
DrawImage(bmpTemp)..<br />
<br />
Does it make sense?? <br />

I received a reply from Sandip but I'm having hard time translating it to code. The process is what i needed it's just that I can't make it work.

First I haven't found a constructor for
Graphics gr(bmpTemp)

and for function
DrawImage(bmpTemp)..

I'm not that good in GDI so I hope somebody can help me.

It will be a big help if you reply. Thanks.

(One overload of )The Graphics constructor accepts a pointer to a CImage object.
DrawImage (as well as RotateTransform) is a method of the Graphics class.

But how will I declare bmpTemp?

?????????<br />
Graphics gr(bmpTemp)

I'm confused on how will I declare this one.
Can yu please show. Thank you.

Did you look at the link i gave.
It shows a graphics constructor which accepts Image class object as a parameter.
Bitmap class is derived from the Image class. So when you will pass the Bitmap object to the graphics constructor it would invoke that constructor.

Now declaration of bitmap.
You can simply create a canvas bitmap which will hold your other bitmaps someting like this.

Bitmap *bmpTemp = new Bitmap(iWidth,iHeight);

Is it clear now???

I have tried

Image *bmpTemp;<br />
Graphics gr(bmpTemp);<br />
.... stitching here

but result to following error,
bmpTemp is being used without being defined.

I don't really know how to implement it.

CPallini8-Sep-08 20:54

For instance

CImage bmpTemp;
bmpTemp.Create(640,400,32);
Graphics gr(& bmpTemp); // please note the ampersand

Bitmap bmpTemp(640,400, PixelFormat32bppRGB);
Graphics gr(& bmpTemp);

Did you follow the link provided by
Sandip?
Have you a good C++ tutorial?

Yes, I have tried also

CImage bmpTemp;

but there is no intellisense for .Create()
bmpTemp.Create();

I have tried including altimage.h but it comflicts to other class I'm using.

Or is there other header to include?

I dont know if CImage is derived from Image.

But you can use

Image *bmpTemp =  new Image(iWidth,iHeight);

Did you try this??
I don't know why are you facing so much trouble in this
Previously you were using hDC directly to draw your bitmaps on.
Now you just have to replace this hDC with temporary bitmap..
and once you finish all your operations do following

Graphics gr(hDC);
gr.RotateTransform(..);
gr.DrawImage(bmpTemp);

Is it clear?

I received an error on this,
I think there is no constructor available.

I am nt sure if constructor is available for the Image class but it is surely there for Bitmap.
What is the problem you facing in following code.

Bitmap *bmpTemp = new Bitmap(iWidth,iHeight);
Graphics gr(bmpTemp);

If you still have problems
Please Look at this section on CP GDI+[^]
I hope it will help you..

I installed VS 2005 Pro on a new machine and went to debug an existing application. The ADO calls to query the SQL server DB are taking a REALLY long time, where they run instantly on the old installs. Are there any global settings that will change the debugger performance? I have all the patches installed, right data sources, same connection string, etc. but it won't run quickly.
