Delete your *.sln file. (only do this if you do not depend on it to load your multiple projects)
rename your file *.vcproj manually in window explorer.
Then, open your renamed *.vcproj in VS IDE.
In your solution explorer, right click on your proj node and select rename.
(I guess this is not simple enough though)
There is another way to do it as well. If your project name is unique throughout your files. Use Find and Replace - Find In Files in your IDE to replace all the name in all your files. But this way is a bit risky.
(I hope there are easier ways to do it)

Hi guys,
is there any article or tutorial shown that how to detect parallel port address of computer automatically?
no i just make simple stuff to work with the parallel port but to make the stuff work on other computers i want to make it can detect the port address automatically instead of key in the address.
Thank U for ur help in advance!!

Hi, Anthony, thank you for reply. i m trying to use the one u suggest. but the code is hard to understand.
in case, i really dun know how the parameter "myPort" which in etAddressLptPort GetAddressLptPortInTheRegistry GetAddressLptPortInTheMemory
hv been used.
u have any idear abt it.
btw i m trying to get that book to c how. thank u very much!

I have a question for any of the experts out there but first here is some code...
I wrote the following code in C# for reading absolutely any file type. It does work perfectly for any file type and the method or style is called a binary file reader....
byte[] buffer = new Byte[SizeBuff];
int bytesRead = 0;
int ByteCounter = 0;
inputStream = File.OpenRead(@InputFile.Text);
while ((bytesRead = inputStream.Read(buffer,0,SizeBuff)) > 0)
{
ByteCounter = ByteCounter + bytesRead;
}
int TotalBytes = ByteCounter;
byte[] ModifyThisFIle = new Byte[TotalBytes];
int KiloByteCounter = 0;
inputStream.Close();
inputStream = File.OpenRead(@InputFile.Text);
while ((bytesRead = inputStream.Read(buffer,0,SizeBuff)) > 0)
{
for (int a = 0; a < bytesRead; a++)
{
ModifyThisFIle[a + (KiloByteCounter * 1024)] = buffer[a];
}
KiloByteCounter = KiloByteCounter + 1;
}
NOT TXT file types and NOT the simple ifstream statements....
What is the simular or identical method for reading each character of a file IN VC++??? "What is included within and including the while loop statements to read" in VC++ for binary files like JPG, HLP, PDF, etc???
Thanks,

You could try the C api.
FILE *fSrc;
if ( (fSrc = fopen(".\\yourfile.bin", "rb")) == NULL)
assert(NULL);
int nLoop = yourGetFileSize(".\\yourfile.bin");
UCHAR *pBuffer = new UCHAR[nLoop +1];
int p = 0;
while (nLoop)
{
pBuffer[p] = (UCHAR)fgetc(fSrc);;
nLoop--;
p++;
}
fclose(fSrc);
delete [] pBuffer;
This will read byte by byte to the UCHAR buffer.
I am sure there are some STL based functions which could do the same.

Thanks very much,
Interesting structure. I am not familiar with the term , "rb" that is located within the if loop but I assume with your above comment it means Reading Binary.
I also noticed something else that is a little bit different are the 2 semicolons ;; located within the while loop. That is new to me as well.
Please Quote me on this but I assume the pBuffer array is where each char is placed then it is deleted with the delete statement after you finnish what ever it is you need to do before you delete the array??? 
Also I noticed that you used UCHAR, I assume you could use BYTE as well???
Are there any special include files I need???

Yes, UCHAR is a unsigned char which has the range of 0 to 255, thus equivalent to BYTE. Reason to use UCHAR is that data type name is self explanatory the reason of using the type, just to save a few comments on your code.
You can not use _int8 or char here because this data type are from –128 to 127.

Why are you reading the file twice and throwing away the bytes read in the first pass? Here's a function to read all the bytes of a file in one pass to a C++ std::vector.
#include <fstream>
#include <vector>
#include <string>
using namespace std;
const int SizeBuff=1024;
typedef unsigned char BYTE;
void readFile(const string& inputFile, vector<BYTE>& buffer)
{
ifstream inputStream;
vector<BYTE> tmpBuf(SizeBuff);
streamsize bytesRead;
inputStream.open(inputFile.c_str(), ios::in|ios::binary);
while(inputStream) {
inputStream.read(reinterpret_cast<char*>(&tmpBuf[0]), SizeBuff);
bytesRead=inputStream.gcount();
if(bytesRead > 0) {
buffer.insert(buffer.end(), tmpBuf.begin(),
tmpBuf.begin() + bytesRead);
}
}
inputStream.close();
}

That was when I was new to C#. I was making the first pass to get the actual number bytes in the file so I could use it to fill dynamic arrays with each character. I did not know at that time what method or call was used to get the size. Yes, I knew before I placed the code on this thread that it is a waste of time to read a file twice. I do know C# now, and I know console C++. Just a couple of days ago I have migrated to VC++MFC which I am still a little bit new at, your help is greatly appreciated.
Thanks markkuk,
Interesting function you have.
Vector is a STL container. You are passing both the "file_path_and_name" and the vector named buffer by reference so it is a void function. You also used a typedef.
So within the main program you could...
vector<BYTE> BufferNumberOne;
readFile("C:\files\picture1.jpg", BufferNumberOne);
for (int a = 0; a < BufferNumberOne.size(); a++)
{
BufferNumberOne[a];
//do stuff like fill array, modify chars, or etc.
}
or would you...
String some_file = "C:\files\picture1.jpg";
vector<BYTE> BufferNumberOne;
readFile(some_file, BufferNumberOne);
for (int a = 0; a < BufferNumberOne.size(); a++)
{
BufferNumberOne[a];
//do stuff like fill array, modify chars, or etc.
}
Please quote me if I am wrong on any of the above statements.
In past C++ courses we used statement like while(!EOF) but EOF is char 26, ^Z and it exists many times within jpg or other such file types that use any or all of the 256 different characters. Not many C++ text books discuss methods in any detail at all on how to read files of types other than txt.
Thanks Much markkuk,

You can call the function both ways, just remember that the standard string type is string, not String. Some error checks should be added to the function before using it in a "real" program.
The constant EOF in C and C++ code isn't the ASCII EOF character, it's an integer value different from any character and can be used with any types of file.

Hi.
I want to add a licensing support to an existing project.
I did this:
Added this two lines to the control's immplementation file:
static const TCHAR BASED_CODE _szLicFileName[] =
_T("License.lic");
static const WCHAR BASED_CODE _szLicString[] =
L"Copyright (c) 1995 ";
then these functions:
BOOL CLicenseCtrl::CLicenseCtrlFactory::VerifyUserLicense()
{
return AfxVerifyLicFile(AfxGetInstanceHandle(),
_szLicFileName, _szLicString);
}
BOOL CLicenseCtrl::CLicenseCtrlFactory::GetLicenseKey(DWORD dwReserved,
BSTR FAR* pbstrKey)
{
if (pbstrKey == NULL)
return FALSE;
*pbstrKey = SysAllocString(_szLicString);
return (*pbstrKey != NULL);
}
but it does not work. I figured out that the license keyword needs to be added to the .odl file, and also a license key created.
Anybody that can direct me to a good site explaining this? Thanks.

How can you stop the Tab key acting as an Enter key during text entry into a Edit Box.
If I enter text into the Edit Box and press the Tab key, then the program acts as if the Enter key was actioned.

I think the tab key was overrided for switching between controls in CWnd.
You could use CTRL D to see the sequence of tab sequence.
My opinion will be override the OnKeyUp of your CWnd for VK_TAB.
But probably there are simpler way to do.

See Michael Dunn's C++ FAQ on this site. It outlines a good method.

I am trying to create a program using the CreateProcessWithLogonW. I am working on a Windows 2000 Professional. The program compiles fine but when it tries to link it, it gives the following errors:
Linking...
CreateProcess.obj : error LNK2001: unresolved external symbol __imp__CreateProcessWithLogonW@44
Debug/CreateProcess.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
Creating browse info file...
CreateProcess.exe - 2 error(s), 0 warning(s)
The code that I am trying to compile is as follows:
#define UNICODE
#define _WIN32_WINNT 0x0500
#define WINVER 0x0500
#include <windows.h>
#pragma comment(lib, "Advapi32")
int main(int argc, char* argv[])
{
STARTUPINFO si;
si.cb = sizeof(STARTUPINFO);
PROCESS_INFORMATION pi;
if (CreateProcessWithLogonW(L"UserName", L"Domain", L"password", LOGON_WITH_PROFILE, NULL, L"\"full file path\"", CREATE_DEFAULT_ERROR_MODE, NULL, L"\"current directory\"", (LPSTARTUPINFO)&si, (LPPROCESS_INFORMATION)&pi)) {
CloseHandle(pi.hThread);
CloseHandle(pi.hProcess);
}
return 0;
