static char check_name[12][5] = {
"A320", "A330", "B320", "B330", "D320",
"D330", "F340", "I320", "I330", "P320", "P330" };
this is how check_name is initialized.

OK, it looks fine. Now, could you please reformat OP code using <pre> tags?

what do you mena by OP code

The (long) code snippet of the original post.
You may also repost it, correctly formatted, of course.

Have you used the debugger to single-step through the code to find the offending statement(s)?

Comment #1: Try to remove "magic numbers" in the code.
Comment #2: check_name is intialized with how many values?
What happens in the following code if, by some chance, check_name[n] is a character string longer than 11?
char check_name[12][5];
char pns_name[12];
sprintf(pns_name, "%s.PNS", check_name[n]);
Comment #3: Walk through code in the debugger. Use small numbers.

I am drawing a bitmap on dc using loadImage() and bitblt method
it is working fine. but my problem is that I cannot change the alpha
values of the image i.e. from 0 - 255

AlphaBlend () API can be used.

but it works with 32bit bitmap I am working with 24 bit.
Trioum
|
|
|
|

AFAIK 24 bit bitmaps have not an alpha channel, Am I wrong?

Sorry for quering .I am reviewing my question again actually
I want to set the transparency of the bitmap i.e. from (0-255).
Trioum

|
|
How are you displaying your bitmap ? And what do you need to do exactly ? Do you only need to have some parts of your bitmap transparent ? If yes, take a look at TransparentBlt[^]
|
|
|
|
|
No transparent blt transparent some part. I want the whole image

Why you can't use 32-bit ones?

Did you try with CImage::AlphaBlend ?
|
|
|
|
|
Do you want to actually alter the bitmap pixel data or
just draw the bitmap with adjustable transparency?
To draw with transparency, you can use AlphaBlend(). The
bitmap does NOT have to be 32-bit, but you need to initialize
the BLENDFUNCTION properly:
BLENDFUNCTION blendfunc;
blendfunc.BlendOp = AC_SRC_OVER;
blendfunc.BlendFlags = 0;
blendfunc.SourceConstantAlpha = 40;
blendfunc.AlphaFormat = 0;
To change the pixel data, load it as a DIBSection and loop through the pixel data
applying alpha to each pixel's data.

yes I want that stuff you are right . but when I am using it
BLENDFUNCTION *blendfunc;
blendfunc.BlendOp = AC_SRC_OVER;
blendfunc.BlendFlags = 0;
blendfunc.SourceConstantAlpha = 40; // Set your transparency (0-255) here!blendfunc.AlphaFormat = 0; //Don't use AC_SRC_ALPHA for 24-bit images - there is NO source alpha data
AlphaBlend(m_DC,0,0,720,576,memDC,0,0,100,100,blendfunc);
where 100 100 is height and width of image
error fires call of non function

blendfunc should NOT be a pointer.
BLENDFUNCTION blendfunc;
blendfunc.BlendOp = AC_SRC_OVER;
blendfunc.BlendFlags = 0;
blendfunc.SourceConstantAlpha = 40;
AlphaFormat = 0;
AlphaBlend(m_DC,0,0,720,576,memDC,0,0,100,100,blendfunc);

On the AlphaBlend() line?
If so, you may need to define WINVER to something >= 0x0400.
This needs to be before any windows or MFC #included header
files.

You can use of CImage class and use of SetPixelRGB.

Solve It .Actually I am using plan SDK .I cannot use CImage.

i have splitter control and there are some items in the control. now i have added a new menu item. created a dialog and the base class is CFormView class. now when i am trying to open this dialog with the menu item its giving me an assertion error. it comes to this line in CFormView.cpp
<br />
if (!_AfxCheckDialogTemplate(m_lpszTemplateName, TRUE))<br />
{<br />
ASSERT(FALSE);
PostNcDestroy();
return FALSE;<br />
}<br />
#endif //_DEBUG<br />
<br />
have given the right IDD for the dialog box. what can be the problem?<br />
<br />

Debug more into _AfxCheckDialogTemplate

Please check the Dialog associated with the Resource ID preexist. If the Dialog is there, you shouldn't get any error.
