Thanks; but I have been writing my own software to handle Windows graphics images and graphics files for many years. I merely need to know how to link an existing bitmap (as identified by its HBITMAP handle), to a device context (HDC), so I can use TextOut(dc,----) etc to write text to the graphics image in the bitmap identified by the hbitmap. Thanks.
(I learned Windows programming in the old days; I do not use classes, except some classes which I wrote for myself.)
Thanks for answering the various queries that I have asked here in the past.

Oh, I see. You just use:
SelectObject(hdc, bm);
Where hdc is the Device context handle (HDC) and bm is the bitmap handle (HBITMAP).

How can I find the size of a file without opening it? Or if I do have to open it, how can I open it and get the file size when it is already open by another application?

The FindFirstFile() API works fine.

I have Windows Vista.
I am writing an image-handling section in a program. The parts relevant here are:
SIZE sz; char T[256]; BITMAP bm;
// Next I set bm.bmType=0; bm.bmWidth=bm.bmHeight=840; bm.bmWidthBytes=2520,
// bm.bmPlanes=1; bm.bmBitsPixel=24; bm.bmBits = address of the bit pattern of an image;
HBITMAP hbm=CreateBitmapIndirect(&bm);
// which should put in hbm a copy of the bit pattern bm
// Here a test showed that hbm!=0
GetBitmapDimensionEx(hbm,&sz);
sprintf(t,"hbitmap is %d * %d",sz.cx,sz.cy);
MessageBox(0,t,"size",MB_OK);
//which showed that sz.cx == 0 and sz.cy == 0, i.e. the bit pattern in hbm is size 0 * 0, and not as in bm.
Please what may be wrong?

You should use GetObject() to get the bitmap's dimensions, not GetBitmapDimensionEx().
From the GetBitmapDimensionEx() docs:
"The retrieved dimensions must have been set by the SetBitmapDimensionEx function."

Hi all,
I am implementing an TFTP server application.
As far as I know a server can not send any data to client until it asks for it.
Till that time it will be in listening mode.
But is there any chance that the server can send any simple command to client with out the initiation of client.??
Please help me.
Regards,
Sunil Kumar

I strongly doubt it. That poses a lot of security risks.

what client? How does the server know of a client until the client connects? This is somewhat of constant in the concept of client-server computing, servers are known, clients are not.

Probably you should not be talking of client-server model
The server has no idea of the client till the client connect to it .
Though TFTP being light weight & using UDP , it cannot know who the client is

Hi all,
How can I convert a number to binary?
For example when I write 10, 1010 appears.
Thanks all.
|
|
|
|

You never convert a number to binary, a number is a number and is independant of how you 'present'it. I guess what you want to do is create a string representing your number in binary notation, right ?
If that is the case, you can use itoa[^] with a base of 2.
|
|
|
|
|
And this[^] article has good info about conversion between Binary,...

Wow, it looks like an awfull article  Why the hell would you want to rewrite those parsing functions ?

Hi!
The following code shows error.
protected:
virtual int_type uflow()
{
int_type v = base_type::uflow();
count_ += egptr() - gptr();
int p = count_ * 40 / size_;
if (p > prev_perc_)
{
std::cout << "*";
prev_perc_ = p;
}
return v;
}
The errors are:
error C2146: syntax error : missing ';' before identifier 'uflow'
error C2433: 'TestGUIApp::int_type' : 'virtual' not permitted on data declarations
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
warning C4183: 'uflow': missing return type; assumed to be a member function returning 'int'
error C2065: 'int_type' : undeclared identifier
error C2146: syntax error : missing ';' before identifier 'v'
error C2065: 'v' : undeclared identifier
error C2653: 'base_type' : is not a class or namespace name
error C3861: 'egptr': identifier not found
error C3861: 'gptr': identifier not found
How do I resolve these errors?

isn't this code comeing from the STL ?
what are you trying to do ?
if the STL is not compiling, it more likely because YOU made an error in YOUR code, and the error is propagating...
didn't you forget a header to include ?
|
|
|
|
|
include header file where the int_type is defined.
-@SuDhIrKuMaR@-
|
|
|
|
|
are you trying to migrate the project from Older VS to New ?
I strongly think you are missing some thing in the " Include Files "
section of the Options-> vc++ directories
check if the path (header) are included in the include path.

I think you need to substitute "int" for "int_type".

I have a bitmap of height 242 and width 242
I need to place this bitmap in Rectangle having an area of height 50 and width 50.
But before placing in the rectangle I need to draw a circle on the bitmap dynamically. and want to know the region so that i can fill color on it.
