i try to use 'swicth', but then i only manage to click number but don't know how to assign picture to that number..

You can use of CImage class for load bmp,jpg,gif,png.
CImage m_Image;
m_Image.Load(your file);

where should i put that code?
i've try to put in like this, but it get error.
<br />
void test(int z){<br />
<br />
CImage m_Image;<br />
<br />
cout << "You have press " << z << endl ;<br />
switch (z)<br />
{<br />
case 1 : cout << "Picture 1 is\n":<br />
m_Image.Load(pic1.jpg);<br />
<br />
break;<br />
.........<br />
....}<br />
}<br />
is it the same as CxImage?

Are you using MFC, or just the Win32 API? Is this a console or GUI appliocation?

just win32 API console application..

Console applications cannot display GUI images.

it is still using c++ programming?
or the different is just the Project?

You can develop a console application using Win32, MFC, or both. You can also develop a GUI application using Win32, MFC, or both.

Hi All,
I use dc.GetPixel() dc.SetPixel() functions to render bitmaps with my color and then StretchBlt on to my Paint dc.I do StretchBlt of around 16 bitmaps on Paint DC.As a result my painting is delayed by 3 secs.
So, Is there any otherway other than GetPixel() and SetPixel() to reduce the delay?
Thanks in Advance
Today is a gift, that's why it is called the present.

A replacement to GetPixel, is to use GetBitmapBits and access the memory directly.
<br />
BITMAP bm= ###;
<br />
int datasize = bm.bmWidth*bm.bmHeight*bm.bmPlanes;<br />
COLORREF* lpClrData = (COLORREF*)LocalAlloc(LPTR, datasize * sizeof(COLORREF));<br />
DWORD ds = GetBitmapBits(hBitmap, datasize * sizeof(COLORREF), lpClrData);<br />
<br />
COLORREF pixelColor = lpClrData[y*imageWidth+x];<br />
<br />
This is much faster that GetPixel...
I haven't had to deal with SetPixel (but i'm sure with the above you should be on your way to finding a solution).

Jubjub,
is this work with any color resolution?I remember that I try something similar in past,...and I remember that I fonund many problem if the system was 16k colors, where 2 Bytes are used to define the pixel color.

What do you mean by this? What are you actually doing with the pixel values?
This would determine how best to efficiently access the pixels IMO.
If you need pixel access then I would recommend using a DIB section, which gives you an HBITMAP
for GDI operations along with a pointer to the pixel bits for direct manipulation.

Hi All,
I'm writing an ActiveX control, and one of the methods needs to return an array of bytes. This array then needs to be used in Javascript and posted via the MSXML2.XMLHTTP (send).
I've create a method in my ActiveX class that returns a VARIANT, but what ever way I try to create the VARIANT, this fails.
Either I get "type mismatch" when I try to use the data returns, or I get a "Variable uses an Automation type not supported in JScript".
Does anyone know some easy way to return a byte array and use in javascript?
Cheers,
Jub

Hello All,
Let me introduce myself. I am a programmer.
I have been implemented encryption algorithm in pure VC++. It is standalone application. It has dialog box for taking source file name (Plain text file) and destination file name (Encrypted text). It is working perfect.
Now I got new requirement that, I have to integrate this algorithm in explorer as toolbar. I created toolbar and integrated my code. Now I have to send some information to server which has been implemented in J2EE. My question is I am which technology I can use to passing information from client VC++ to server J2EE. And also server will send response client has to process.
I have to implement client side program and one of my friend is working in server. He is asking to provide jar file. Can I know how can I do that? Or Can I use JNI or DCOM server? Please suggest me on this.
Thanks in advance,
Chandu

thats not the problem buddy.. which ever technology u use it will work. because the network protocols are independent on the technologies.. so when u r communicating between server and client that communication is between two sockets ....

Actually, you can do Win32 API programming (even plain C) with Visual C++ .
