How can I get all folder names if specified folder, lets say "c:\new folder\" I want names of the all folder in new folder

Use FindFirstFile and FindNextFile.
The WIN32_FIND_DATA member dwFileAttributes will tell you if the file is a directory.

Hi all,
got a question thats bugging me. I can not figure out this very simple compile error I am getting. Here is the error:
C:\Documents and Settings\mininet\My Documents\C++\9APR09\test.cpp In function `int main()':
28 C:\Documents and Settings\mininet\My Documents\C++\9APR09\test.cpp expected primary-expression before "GetLocalComputerName"
28 C:\Documents and Settings\mininet\My Documents\C++\9APR09\test.cpp expected `;' before "GetLocalComputerName"
I know its related to the string. but what is wrong with it? If you tell me whats wrong, dont just tell me. Please include a description of why the string is messed up. Thank you in advance! Code is as follows:
<code>// Project 01 by Rob
#include <iostream>
#include <string>
#include <windows.h>
using namespace std;
int main()
{
system("CLS");
string password;
string GetLocalComputerName;
cout << "password: ";
cin >> password;
if (password == "123"){
system("CLS"); // Cleares the screen
cout << "password accepted" << endl;}
else{
cout << "password incorrect" << endl;
goto exit;}
exit:
system("CLS");
system("TITLE Local Computer Name");
string GetLocalComputerName()
{
TCHAR chrComputerName[MAX_COMPUTERNAME_LENGTH + 1];
string strRetVal;
DWORD dwBufferSize = MAX_COMPUTERNAME_LENGTH + 1;
if(GetComputerName(chrComputerName,&dwBufferSize)) {
strRetVal = chrComputerName;
} else {
strRetVal = "";
}
return(strRetVal);
}
//std::cin.ignore( std::numeric_limits<std::streamsize>::max(), '\y' );
return 0;
}
V/R

it is a string, i could have called it anything. But I kept it familiar with the function. All I am trying to do is retrieve the local computer name.

No, it's the beginning of a nested function, which is not allowed.

Hello Rob,
You've defined GetLocalComputerName() inside main(). Nested function definition is illegal. So move GetLocalComputerName() outside to resolve the error.
Regards,
Jijo.

First off thank you very much. I read into the embeded function and your right, it will not work.
I do however feel there is something missing. I relocated the entire section related to retrieving the local computer name, to outside int main().
I think there needs to be
#include <fstream>
and have string GetLocalComputerName; cin >> or output somehow. Because the program compiles, yet it dosent seem as if it is doing anything. After I type in the password, it should jump to the next sequential portion of the program, and retrieve the username. It does nothing but stare back at me. I feel as if I am missing something, can someone point me in the right direction? I do a lot of reading but the reading needs to be put into perspective. Thank you very much in advance.
V/R

Hi Rob,
You should call GetLocalComputerName() function and print it. For instance, see the corrected code snippet.
#include <iostream>
#include <string>
#include <windows.h>
using namespace std;
string GetLocalComputerName()
{
TCHAR chrComputerName[MAX_COMPUTERNAME_LENGTH + 1];
string strRetVal;
DWORD dwBufferSize = MAX_COMPUTERNAME_LENGTH + 1;
if(GetComputerName(chrComputerName,&dwBufferSize)) {
strRetVal = chrComputerName;
} else {
strRetVal = "";
}
return(strRetVal);
}
int main()
{
system("CLS");
string password;
cout << "password: ";
cin >> password;
if (password == "123"){
system("CLS");
cout << "password accepted" << endl;}
else{
cout << "password incorrect" << endl;
goto exit;}
exit:
system("CLS");
system("TITLE Local Computer Name");
cout << GetLocalComputerName();
return 0;
}
Regards,
Jijo.

I'm looking at using some of the new stuff that comes from the MFC Service Pack in our current application (possible release date for this is late this year, so it's not urgent)
We have at least one resource ID conflict between our resources and the new resources in the Service Pack.
for example :
our code:
#define IDS_MESSAGE_FORMAT 17018
MFC code:
#define IDS_AFXBARRES_ADD_REMOVE_BTNS 17018
What's the best strategy to clean up resources to prevent/limit/remove conflicts ?
I have used ResOrganiser[^] and it works ok, but looking for preentive solutions.
Thanks.

The code I'm writing is designed to read into a Smart Card Reader. However, I've having a most difficult time trying to just setup the connection and get the filename so I can use CreateFile.
I've looked at the MSDN Library and done countless searches on the topic and have seen various things. Some people allocate the SP_DEVICE_INTERFACE_DETAIL_DATA struct, and claim it works, and some don't and they also claim it works (Both of which do not work for me).
The current way my code is set up right now pulls the required size, but when it goes to fill in the struct, the program freezes. Quite frustrating, really.
So here's my question: What must I do to the struct prior to attempting to fill it in with SetupDiGetDeviceInterfaceDetail in order to pull up *->DevicePath ??
Here's the code:
....
//declarations
int n=0, result;
char af[80]="";
bool found=FALSE;
GUID SCRGuId;
DWORD requiredsize=0;
HDEVINFO hDevInfo=NULL;
SP_DEVICE_INTERFACE_DATA DeviceInfoData;
PSP_DEVICE_INTERFACE_DETAIL_DATA DevDetailInfoData;
....
do
{
if(SetupDiEnumDeviceInterfaces(hDevInfo, NULL, &SCRGuId, n, &DeviceInfoData))
{
found = TRUE; requiredsize = 0;
SetupDiGetDeviceInterfaceDetail(hDevInfo,&DeviceInfoData,NULL,0,&requiredsize,NULL);
sprintf(af, "reqsize: %d", requiredsize);
SendDlgItemMessage(hWnd, IDC_ACTIONLIST, LB_ADDSTRING, 0, (LPARAM)(LPCSTR)af);
if(requiredsize != 0)
{
//this is the problem code...can anybody help me here?
DevDetailInfoData->cbSize = sizeof(SP_DEVICE_INTERFACE_DATA);
SetupDiGetDeviceInterfaceDetail(hDevInfo,&DeviceInfoData, DevDetailInfoData,requiredsize,0,NULL);
sprintf(af, "device path %s", DevDetailInfoData->;DevicePath);
SendDlgItemMessage(hWnd, IDC_ACTIONLIST, LB_ADDSTRING, 0, (LPARAM)(LPCSTR)af);
}else{
....

I use this approach when querying audio devices using the ANSI API's ...
<pre>
// Get details for the device registered in this class
DWORD size = sizeof(SP_DEVICE_INTERFACE_DETAIL_DATA) + MAX_PATH * sizeof(WCHAR);
// use vector so it will clean up afterwards
std::vector<BYTE> buffer(size,0);
// set up the pointer
SP_DEVICE_INTERFACE_DETAIL_DATA* pDevInterfaceDetails =
reinterpret_cast<SP_DEVICE_INTERFACE_DETAIL_DATA*>(&buffer[0]);
// let SetupDi know how big a buffer we have ...
pDevInterfaceDetails->cbSize = sizeof(SP_DEVICE_INTERFACE_DETAIL_DATA);
// get the device path ...
if (!SetupDiGetDeviceInterfaceDetail(hDevInfo,&DID,pDevInterfaceDetails,size,NULL,&DevInfoData))
{
continue;
}
Apologies for CP formatting ...

Hi, I've set breakpoints in my application. Last night my breakpoints were being hit ok. This morning none of the breakpoints that are set are being hit. So I deleted the project's NCB file. Spurious results at best. I deleted the NCB file again, restarted, cleaned project then rebuilt and my breakpoints are being hit again. Yeah.
However, if I set new breakpoints those breakpoints are missed/skipped.
WTH?

In VC6 at least, breakpoints are stored in the .opt file. .ncb is a pest that gets corrupted regularly by intellisense!

Didn't know the OPT was used for that! Thank you!! :P
I was able to get it to work - after I deleted all my breakpoints. I'll now next what to do ahead of schedule.
Cheers!!
