Simply because your image will be recognized as an image within the pdf file. So you cannot extract text from an image.
From the link you gave us, they probably do character recognition inside their program.

Hi,
I want to add ATL support to an MFC extension DLL in VC++.
You know that VC++ can add ATL support to regular DLLs but does not add this support to MFC extension DLLs.
Is there any way to add ATL support to MFC extension DLLs.
Should I convert the MFC extension DLL to a regular DLL first?

I am wondering about what's the best and easiest way to strip trailing whitespace from every single file in a folder, recursively.
I want to write a program/script so that you pass in a folder name and it'll recursively go through all sub-folders and strips trailing whitespace from every single file.
Trailing whitespace includes:
1. whitespaces at end of text lines, strip whitespace but retain text
2. whitespaces on empty lines, strip whitespace but leave the empty line

Open the file. Set the file pointer to the end using SetFilePointer(). Read the character. If it is non-white, call SetEndOfFile() and close the file. Otherwise, read the previous character...

See following code:
main (....)
{
CString strPath = "*.*";
Trim (strPath);
}
void Trim (CString &strPath)
{
CFileFind Info;
CStdioFile File;
CString strRecord;
BOOL bLoop;
bLoop = Info.FindFile ((LPCTSTR)strPath, 0);
while (bLoop)
{
bLoop = Info.FindNextFile ();
if ( Info.IsDirectory ()
&& !Info.IsDots ())
{
CString strSub;
strSub = Info.GetFilePath ();
strSub += "\\*.*";
Strip (strSub);
}
else if ( !Info.IsDirectory ()
&& !Info.IsHidden ()
&& !Info.IsReadOnly ())
{
printf ("%s\n",(LPCTSTR)Info.GetFilePath ());
if (File.Open ((LPCTSTR)Info.GetFilePath (), CFile::modeReadWrite|CFile::typeBinary, NULL))
{
DWORD dwReadPosition = 0;
DWORD dwWritePosition = 0;
UINT nRecord = 0;
try
{
while (File.ReadString (strRecord))
{
dwReadPosition = File.GetPosition ();
strRecord.TrimRight ();
File.Seek (dwWritePosition, CFile::begin);
File.WriteString ((LPCTSTR)strRecord);
File.WriteString ("\r\n");
dwWritePosition = File.GetPosition ();
File.Seek (dwReadPosition, CFile::begin);
printf ("%d\r",++nRecord);
}
printf ("\n");
}
catch (CFileException *Exception)
{
Exception->Delete ();
fprintf (stderr,"\nError writing to file\n");
File.Close ();
exit (1);
}
File.SetLength (dwWritePosition);
File.Close ();
}
}
}
}
This code example expects you use MFC. If you don't, you will have to use the standard FILE * type of routines.
Good luck.

Can someone tell me how a '+' operation is internally handled by the compiler(if possible with an example). Meaning that if I say 5+10 wat happens internally and how the compiler handles it??
|
|
|
|

From what I understand, all a compiler does (MSVC for example) is to convert your source code into machine readable code called ASM. If you google around you can find many examples of this language, which in turn will give you a better idea of what is actually happening behind the scenes.

Not quite. Assembly is just another language, although not as high-level as C. What the compiler and linker do is create machine code that matches the instruction set of the processor.

On a very low level, you change the current in some transistors so that the resulting transistor combination of open and closed transistors is interpreted as 15 by your computer.

this is how VC8.0 handles this:
int a, b, c;
a = 5;
<code>00416C23 mov dword ptr [a],5 </code>
b = 10;
<code>00416C2A mov dword ptr [b],0Ah </code>
c = a + b;
<code>00416C31 mov eax,dword ptr [a]
00416C34 add eax,dword ptr [b]
00416C37 mov dword ptr [c],eax</code>
codito ergo sum

Regarding these resource files I know it is possible to store just about any type of binary data, but the problem is access. I am trying to include an Excel .xls file into my project. Including this as a plain file is no problem, but when added as a resource I have trouble accessing it. Namely with functions that expect a string pointer.
This xls file is the master template for which my program would copy/fill-in/manipulate. Therefore I would prefer it to be hardcoded into the exe where it would be pretty much impossible to be deleted or edited.
Is there a workaround or a method of conversion?
|

If I'm interpreting your situation correctly, you're saying you have an 'integer' identifier (defined in resource.h) for your Excel resource and need to know how to form the 'string' value that can be used to reference it.
To convert that integer value to a 'string' (wink, wink) Microsoft provides the MAKEINTRESOURCE[^] macro.
Is this what you are looking for?

Dan

Hi All,
How to write an email application from VC++?
Thanks in advance,
Awating your reply,

What you have to do ?
Do you have to just send the message or anything else.
Cheers

If you just need to send an email to a specific address, you can just ShellExecute that email address (similar to how you invoke a url).
ShellExecute(hwnd, "open", "mailto:your.address@domain.com", NULL, NULL, SW_SHOW);
You can even supply a body/subject by crafting the mailto like a Query string (MSDN[^]):
mailto:your.address@domain.com?body="This is the body"&subject="Auto-generated e-mail subject"
If you need more advanced functionality (such as choosing your server), check the forum Q&A FAQ.
