Thanks for the both replay. But I'm not sure that is easy to me 
This is the way I've done it.
<br />
void CSRFDBDlg::CheckFileName(CString FileNameToCheck)<br />
{<br />
CString withExt;
CString fileExt;
<br />
withExt = FileNameToCheck.Right(FileNameToCheck.GetLength() - (FileNameToCheck.ReverseFind('\\') + 1));
<br />
fileExt = withExt.Mid(14, 3);<br />
<br />
if( (withExt.GetAt(0) == 'G') && (withExt.GetLength() == 17) )<br />
{<br />
if( (fileExt.GetAt(0) == 's') && (fileExt.GetAt(1) == 'r') && (fileExt.GetAt(2) == 'f') )<br />
{<br />
CString str( _T("Selected Target:\n\n" + FileNameToCheck) );<br />
AfxMessageBox(str, MB_OK);<br />
GetDlgItem( IDC_READ )->EnableWindow( TRUE );<br />
}<br />
else<br />
{<br />
AfxMessageBox( "This file format is not support in this application." );<br />
}<br />
}<br />
else<br />
{<br />
AfxMessageBox( "This file format is not support in this application." );<br />
}<br />
}<br />
I appreciate your help all the time...

If you use CArchive::Serialize it will check if the structure of the data are correct to the project it self.
I.E. you code this:
if (ar.IsStoring ())
{
ar << myObject.myInt;
ar << myObject.myDouble;
ar << myArray[x].myString;
}
and you save a file with those datas, if you afterwards try to read them and you put it in other way, like:
else
{
ar << myArray[x].myString;
ar << myObject.myDouble;
ar << myObject.myInt;
}
the programm will complain and say that the data are not readable. So there is an error coding, or the file is not from your application. Is very difficult to find a "fake" file with the same structure of data as the files from your application (probability will be inverse proportional to the ammount of data saved in your file).
With the CFile you dont have that support, so you should use the solutions above.

Thanks pal. How about if I check both structure(as you said here) and the way the file name organized(as my code). Is it good or bad.
I appreciate your help all the time...

This is a simple assignment for my c++ class requiring us to convert some text in a char array inline, not using another array. My code compiles with no errors, but when I run the program nothing comes out. I guess somewhere I'm accidently overwriting the entire string to nothing but... yeah. Anyhow, in the array, the following changes are supposed to occur: th -> z, s -> z, and r -> rr. This, of course, requires the entire string to be shifted if in the cases of th -> z and r -> rr. Here is my code:
<br />
#include "stdafx.h"<br />
#include <br />
#include <br />
#include <br />
<br />
using namespace std;<br />
<br />
#define MAX_SIZE 100<br />
<br />
int getLength(char inputText[]);<br />
void moveLeft(char* inputText, int index);<br />
void moveRight(char* inputText, int index);<br />
<br />
<br />
void main()<br />
{<br />
<br />
char text[MAX_SIZE];<br />
<br />
cout << "Enter your words here: ";<br />
cin.getline(text, MAX_SIZE);<br />
<br />
int sizeText = getLength(text);<br />
<br />
int j;<br />
int k;<br />
<br />
for( j = 0, k = 0; j < sizeText; j++, k++)<br />
{<br />
if ( (text[j] == 't' || text[j] == 'T') && (text[j + 1] == 'h' || text[j + 1] == 'H'))<br />
{<br />
text[k]= 'z';<br />
moveLeft(text, k);<br />
j++;<br />
}<br />
else if (text[j] == 'r' || text[j] == 'R')<br />
{<br />
moveRight(text, k);<br />
text[k] = 'r';<br />
text[k+1]= 'r';<br />
k++;<br />
}<br />
else if (text[j] == 's' || text[j] == 'S')<br />
{<br />
text[k] = 'z';<br />
}<br />
<br />
}<br />
<br />
cout << "The new line is: " << text << endl;<br />
<br />
}<br />
<br />
int getLength(char inputText[])<br />
{<br />
int length = 0;<br />
while (inputText[length]!= '\0')<br />
{<br />
length++;<br />
}<br />
<br />
return length+1;<br />
}<br />
<br />
void moveLeft(char* inputText, int index)<br />
{<br />
for (int i = index; inputText[i] = '\0'; i++)<br />
{<br />
inputText[i] = inputText[i+1];<br />
}<br />
}<br />
<br />
void moveRight(char* inputText, int index)<br />
{<br />
for (int i = 100; i > index; i--)<br />
{<br />
inputText[i] = inputText[i-1];<br />
}<br />
}<br />
Any help that you could provide would be greatly appreciated! Thank you!

I guess here is the mistake :
for (int i = index; inputText[i] = '\0'; i++)
you're assigning it ! Correct it as :
for (int i = index; inputText[i] == '\0'; i++)
Better keep habit of placing constants at left side of '==' and variables at right side while comparing (conditions). i.e.
for (int i = index; '\0' == inputText[i]; i++)
This would raise compiler error itself, if you put single '=', rather double '=='.

It's a common mistake to simply look at a program's output in determining if it's correct or not. Instead, you should use the debugger and step through each line of code to verify whether or not it's doing what you expect. Using that approach, you can easily narrow the problem to a statement or two.

With IOCP, you are responsible for creating a pool of threads.
Any thread waiting on GetQueuedCompletionStatus() is part of the IOCP's "thread pool".

Hey Guys,
I'm working on a graphics app. There will be a form that allows the user to find/select a image from hundreds of stored art. My question is: How can I "load" hundreds of images effeciently? I know MS gives you a listviewbox to work with but it is terribly slow and cumbersome when dealing with so many images. 
Popular graphics programs like PrintShop gives you hundreds of images in one area with seemingly no load time. Any tips on how to accomplish this?
Richard
may your code be error free.
(okay, maybe two lines.)

I have seen a lot of samples around which passes the processing to a thread. This will make your application still available for the user to interact with while the thread processes the loading of image. The rest will rely on your algorithm of loading each image to the form. Optimize your codes for faster processing.

hi all,
i'm using ADO and datagrid in my project, which is working fine in my machine. But when i made a setup and ran in another machine it was not working , there is problem in loading the ADO or data Grid. DSN name is coming correctly since i included the code for that when i made set. i also included the all the MFC dll(like MFC42.dll,etc) which i used to include.
Should i include any other dlls or any registry entry when i use these(ADO n data Grid ) when i make setup?
kindly reply,
thanks in advance...

Use the vc tool "Depends" you already have to find all the dlls your progam depends on.
