hello guys... i have two projects. Now from Project 1, I copied all the necessary (XYZ.h) and (*.cpp) files to Project 2. Then I added them (Project->Add Existing Item) to the Project 2. But when I run the Project 2, it complains that
fatal error C1083: Can not open include file: 'XYZ.h' No such file or directory
whats wrong??

At a guess it cannot find "XYZ.h". Take a look in your project directory and make sure the file is in the correct place.

well i have done this once again. The file is in the directory. Is there anything else that I am forgetting?

Try right-clicking the #include "xyz.h" directive and selecting Open. Does it? From where?

Why do you need to post the same message three times? Post it once and wait; if anyone has the answer they will give it to you, if not you may have to do some research for yourself.

Use this
#define CONNECT_STRING _T("DSN=mmmmmmm;UID=sssssss; PWD=gggggg")
m_pDBConn = new CDatabase();
BOOL w_bIsOpen = FALSE;
if(m_pDBConn)
{
try
{
//opens a connection to the data source
w_bIsOpen = m_pDBConn->OpenEx(CONNECT_STRING);
}

Hi all,
i m reading a text file by using CStdio file,i want when i redaing the file and find the purticular line now i want to update it.

Hi,
The only updates you can do on a text (sequential) file is appending or shortening.
So if you want to change something 'inside' you must create a new file and write there [unchanged beginning][changed part][unchanged ending].
Then you can delete the original file and rename the new file with the original name.
cheers,

is there no onther option to update file without deleting old file and create new file.

There is no other safe option. If you are adventurous you can
1 Shorten to [unchanged beginning]
2 Append[changed part]
3 Append[unchanged ending]
If a power failure (or like problem) occurs during this processing you may have lost [changed part] and [unchanged ending].
cheers,
AR

In addition to the previous answer: most of the case, when manipulating files, you read them completely in memory and works directly with the data in memory. When you modify the information and have to save your changes, you recreate the complete file at once.
|
|
|
|
|
Another way to do this would be to memory map the file.
This way you can simply modify the contents and they will be automatically saved to disk by the Lazy Writer component of the Windows kernel.

The size can be controlled by mapping more views and using SetEndOfFile.

Don't you think it's slightly overkill for the OP?

You're right.
There are so many crazy ways to do things.

Hey, I just came across a little problem and wanted to ask for your guys opinion.
What would be the most elegant solution to fix this little issue.
if (GetDriveType(drv) == DRIVE_FIXED)
{
GetDiskFreeSpaceEx(drv,0,&DiskSpace,&FreeDiskSpace);
itoa(GetTickCount()/1000%60,ds,10);
itoa(GetTickCount()/1000%60,fs,10);
string temp = "test " + ds + " dasd" + fs;
}
error C2110: '+' : cannot add two pointers

You did not show how ds and fs were declared, but one way might be:
string temp = string("test ") + ds + string(" dasd") + fs;
