You can read .txt, and .csv with relative ease (CFile, if you're using MFC). Other formats are not text-based and you will need to use the respective APIs/techniques to access those.
I can think of office automation for reading .xls and .doc files, and haru[^] to deal with .pdf files.
There are some articles that demonstrate reading from .doc and .xls, etc., files here at CP and you could do a search to find them out.

Hi Dude,
You try the following Code, hope it can help u reading the files.
Try to reduce the code, its too lengthy....
/****** This function is made to search a given string in the file and returns 1 or 0 *****/
int Search_Tag(char* input_line, char* tag_value)
{
int tag_len=0;
Flag=FAIL;
while(*input_line !='\n')
{
if(*tag_value=='\0')
break;
else
{
while(*tag_value!='\0')
{
if (*input_line==*tag_value)
{
input_line++;
tag_value++;
Flag=PASS;
}
else
{
Flag=FAIL;
input_line++;
tag_value++;
}
}
}
}
if(Flag==FAIL)
return FAIL;
else
return PASS;
}
/******This function searches the next occurance of the given string in the file******/
GetNext(FILE *ptr_read_file, char *str)
{
while(1)
{
fgets(line_buffer, 200, ptr_read_file); // read the input file line by line
if(Search_Tag(line_buffer, str))
{
break;
}
}
return 0;
}
/***** This function traverses through the whole file and gives the position of the given strings *****/
int Search(FILE *ptr_read_file, char *str1, char* str2)
{
while(1)
{
fgets(line_buffer, 200, ptr_read_file); // read the input file line by line
if(Search_Tag(line_buffer, str1))
{
GetNext(ptr_read_file, str2); //Find Second Parameter
break;
}
}
return 0;
}
/*********** Reading the File *************/
void CABCDlg::OnButton1()
{
// TODO: Add your control notification handler code here
ctr++;
if(ctr == 1)
{
fp1 = fopen("File 1.txt","r");
//if the file doesnot exist or cannot be opened then return
if(fp1 == NULL)
{
MessageBox("File Not found 'File 1.txt' Check source directory and try again...","Error",0);
ctr--;
return;
}
fp2 = fopen("File 1.txt","r");
fp3 = fopen("File 1.txt","r");
Search(fp3, "Object number: 2", "Message contents");
fgets(line_buffer, 200, fp3);
/*********** READ 1st Four Bits From the File *********/
for(i=0; i<4; i++)
{
msg[i] = (fgetc(fp3));
}
m_txt1 = msg;
UpdateData(FALSE);
}
}
** Similarly u can read the .csv(dot csv) files as well.
Note: Save the files in the same folder where .dsw was saved, to save the search time.

Implement a program to find out whether a trial string is an anagram of a source string.
Anagram: The result of rearranging the letters of a word or phrase to produce other
words, using all the original letters exactly once.
Examples: “Dormitory”: Dirty room
: “Mother in law”: Women hitler
: “Desperation”: A rope ends it

Hi Abhishek,
See there are some things that you need to understand before asking a question.
1. Read the Guidelines that is available as the first link in the forum
2. You know what you should do. So try to solve the problem.
3. Do Something and if you are stuck then come back to the Guru's. There are people here to help here. This is not the right way to ask a query.
And i am really surprised why Rajesh was not annoyed and was not commenting on seeing his slang

HI
SRY I DINT MEAN THE CODE EXACTLY...I HAVE GIVEN A THOUGHT ABT IT BUT I DINT COME 2 ANY PROPER IDEA SO I JUST WANTED ANY1 TO SUGGEST ME ANY STARTUP WITH THIS.....I THOUGHT ABT USING BACK TRACKING ALGORITHM BUT FOR THT THE WORDS NEED TO BE IN A SEQUENCE....SO I WANTD 2 KNOW ANY SPECIFIC ALGO I GOTTA USE OR ANY OTHER JUST A START UP IDEA

There are some more things that you need to know.
1. Using Capital letters is like shouting. So try avoiding it.
2. Don't use slang's. For example: If you can type "Abt" there is nothing wrong in typing About. doesn't take much of time.
3. Don't just type something, understand the problem.

If you haven't read the guidelines[^], I'd suggest that you read it now (specifically point numbers 2, 6 and 9).

Well, aside from warnings you are getting from others (apply to them please) I'm getting few ideas:
- in anagram all letters must be used (from source string), and only one time (can't re-use the same letter).
Chack for length (without spaces) it must be equal.
Next you can use source string as matching point, start from first letter and check for existing in trial string. If it exist remove it from both strings, if it doesn't your trial string is not an anagram.Preform that operation until you check all letters. If an empty string is what is left than yours trial string is indeed an anagram.
Hope this helps.

Hi,
I want to programmacally create an entry under
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run in Vista to make my application to Load at windows start up. But when trying to create an entry RegSetValueEx return Access denied error. How can i add an entry under Run programmatically using VC++. Whether there is any API to get an access right to Vista Registry. I am using Vista Home and VS 2005 to develop my application.
thanks
Nitheesh.

Hi there,
I'm having problems getting an HTML element from a CDHtmlDialog.
Here is my scenario:
I need to create a Dialog in which to display a HTML page with some textareas. These textareas need to be filled dynamically from my code. The purpose of this Dialog is somewhat resembling a preview dialog. I need to show the end user how a pdf will look like and allow the user to modify some data just before creating the pdf.
So, I used CDHtmlDialog, I loaded the page using Navigate(fileURL)(please be aware that I cannot store the htmls as resources because I will need to load a relatively large number of them, so I would prefer loading them straight from the disk), and now I want to populate the textareas .
To do that, I used this chunk of code that I found browsing the web:
IHTMLElement* pLinkElement = NULL;
if (GetElement(_T("text_id"), &pLinkElement) == S_OK && pLinkElement != NULL)
{
pLinkElement->put_innerText(text_value);
}
The problem is that GetElement returns an E_NOINTERFACE error message.
This happens when I'm using this code on the OnInitDialog() method, right after using Navigate().
I also intercepted some OnClick messages for a few buttons in my HTML (using the DHTML_EVENT_MAP). If I use the code above on one of those OnClickButton() methods, the code works fine.
Does anyone have an ideea why this would happen?
Thanks in advance,
Paul.

It's been a long time since I tried to hijack the browser to create a user interface but you may have to wait until the browser had built the DOM. There are events it fires like documentComplete or some such thing.

Thanks a million man! You saved me from a nervous breakdown (and, of course, from a stupid workaround, VERY bug prone)  .
Indeed, calling the code in the OnDocumentComplete() did the trick.
I ow you a beer

Hello, sorry for the late reply.
I think you should use the OnDocumentComplete method and not use OnInitDialog method because the html element only ready to be used after the document has been fully loaded.

in MFC application am using JPEG images which are using as background images for my dialogs. fro the am carrying image filtes with my application instead of that can i set imaged into dll and load the images from dll whenever required?
|

Yes. Add them into the resource file. I've added an HTML file (contained in the 'res' sub-directory of my project) to my resources using this entry in the resource (.RC) file:
ABOUTDIALOG.HTML HTML "res\\aboutdia.htm"
You could use (for example)
TEST.JPG JPG "res\\test.jpg"
You can then use a code fragment like the following to load a resource into memory:
std::string LoadFileFromResource(HINSTANCE hmodResource, LPCTSTR name, LPCTSTR type)
{
if (!type)
type = ::PathFindExtension(name) + 1;
HRSRC rsrcFile = ::FindResource(hmodResource, name, type);
if (!rsrcFile) return std::string();
HGLOBAL gblFile = ::LoadResource(hmodResource, rsrcFile);
if (!gblFile) return std::string();
DWORD sizeFile = ::SizeofResource(hmodResource, rsrcFile);
if (!sizeFile) return std::string();
LPVOID filePointer = ::LockResource(gblFile);
if (filePointer)
{
std::string contents((char*)filePointer, sizeFile);
::FreeResource(gblFile);
return contents;
}
return std::string();
}
[edit]You'd call that function a bit like this:
std::string loadedJpeg = LoadFileFromResource(resourceDllHandle, _T("TEST.JPG"), _T("JPG"));
std::string might not be the best result type for you, as you're loading a binary file - I've only loaded text files with this...[/edit]
