Hello . I want a simple program with 2 form
1. ask User name and password and if it is true then I have permission to use second form
2. in the second form I have registration form and database permission for user that after they registered they can recive one user name and pass then they can use the application .
thank you for your help .

Offline or Online?
Offline apps that ask for username and password can use simple file i/o for login if you wanted to... the second form (registration form) could also be easily done with fstream and calling the login part to read from exact file... dats if u wanna do it easily... Online, im stuck on that as well but ill let u know when i get it 
If you need help with offline logins then i could help you with what you need, im sure others here will be glad to give u links to articles thatll help you with server logins... There are many articles relating to login authorization, just use the search button

Can anyone who have or know where i can get the header file of <unistd.h> help me with it. I tried to search it but the search was fruitless
-oam-
|
|
|
|
|
which header file ?

|
|
|
|

Sory i thought i posted it
#include unistd.h
thanx

Are you developing on UNIX? .. I Tlooks like it's a UNIX specific header file
see: [^]
for my google results... I also found this http://aegis.sourceforge.net/doxygen-html/unistd_8h-source.html[^] which is *A* uninstd.h file .. but i have doubts that it's the one specific to the application you are trying to compile ....
IF you can provide details about the application / source / where it was obtained from / what platform your working on etc... I will do my bes to help you out ...
Regards

Question is, what good is a header file to him anyhow ? I suspect he's got code that includes it, and he has no idea that the header file needs at least a lib file to link to before it's worth anything.

OK - as I thought. You're more than a little lost here. A header file describes functionality that needs to be provided either in matching .cpp files, or in a library file. The compiler is asking for the header file now, but if you provide it, you will get linker errors from here to sundown, because you will have a file that promises the compiler that you'll tell it how to impliment functions you're describing now, sometime later. You will not meet that promise, and so your code will still not work ( unless this is an inline class that's all in the .h file, implimentation as well as interface, but that seems unlikely ).

Did you check the code i sent there
headers are
#include <stdio.h> /* has definitions of printf, fprintf, fopen, fscanf,
fclose, fflush, perror, rename and BUFSIZ */
#include <stdlib.h> /* has definitions of getenv and exit */
#include <unistd.h> /* has definition of sleep */
#include <string.h> /* has definitions of strcpy and strcat */
therefore i thought the header file will take care of the definition of sleep and that there header file is standard like some headers files that you can get them from somewhere and use them

No, you need to check 'Do not treat <'s as HTML tags' so I can see this code, for what it's worth
mpapeo wrote:

It will take care of the 'definition', that is, it will define the interface, the functions/structs/classes provided elsewhere. It won't give you the code you need to make those things work. The standard library headers, such as iostream, define exactly that, and have corresponding .cpp files which are in directories that your compiler includes in it's searches by default. So they get compiled and linked into your project, no problem. You can't just add other header files to do the same thing, without making sure you are linking to a library, or have the implimentation files available to the compiler also.

True, but not always. Some of them have typedef and struct declarations only. I've no idea what mpapeo is looking for, however.

Yeah, and some contain the entire class ( can't they ? ). I said as much before, but in restating it, I was less careful

I've generally found that you can just delete this line and it will work under Windows. Don't quote me on that though, it may not work at all.

Hello, I'm parsing an XML on a deskband client using SAX: Here is the code:
<br />
CoInitialize(NULL); <br />
ISAXXMLReader* pRdr = NULL;<br />
<br />
HRESULT hr = CoCreateInstance(__uuidof(SAXXMLReader), NULL, CLSCTX_ALL,<br />
__uuidof(ISAXXMLReader), (void **)&pRdr);<br />
<br />
if(!FAILED(hr)) <br />
{<br />
hr = pRdr->putContentHandler(&m_whizzWnd->m_whizzHandler);<br />
<br />
VARIANT var;<br />
VariantInit(&var);<br />
V_BSTR(&var) = SysAllocString(wresp.c_str());<br />
V_VT(&var) = VT_BSTR;<br />
<br />
hr = pRdr->parse(var);<br />
<br />
VariantClear(&var);<br />
<br />
pRdr->Release();<br />
} else {<br />
MessageBox(NULL, TEXT("Error"), NULL, MB_ICONASTERISK);<br />
}<br />
<br />
CoUninitialize();<br />
The problem is that I have reports of memory leaks generated by that code. I'm detecting the memory leaks with the following code after the last include in all my cpp files:
<br />
#include <crtdbg.h><br />
<br />
#ifdef _DEBUG<br />
#define new new(_NORMAL_BLOCK, THIS_FILE, __LINE__)<br />
#undef THIS_FILE<br />
static char THIS_FILE[] = __FILE__;<br />
#endif<br />
And with the following class (I create an instance to begin test and get a memory leak report when the instance is deleted).
<br />
class FindMemoryLeaks<br />
{<br />
_CrtMemState m_checkpoint;<br />
public:<br />
<br />
FindMemoryLeaks()<br />
{<br />
_CrtMemCheckpoint(&m_checkpoint);<br />
};<br />
<br />
~FindMemoryLeaks()<br />
{<br />
_CrtMemState checkpoint;<br />
_CrtMemCheckpoint(&checkpoint);<br />
_CrtMemState diff;<br />
_CrtMemDifference(&diff, &m_checkpoint, &checkpoint);<br />
_CrtMemDumpStatistics(&diff);<br />
_CrtMemDumpAllObjectsSince(&diff);<br />
};<br />
};<br />
Any way, I have two kinds of memory leaks reports, the nice ones (no problem because I have file/line number)
<br />
Data: << r e s p o n s > 3C 00 72 00 65 00 73 00 70 00 6F 00 6E 00 73 00 <br />
c:\eclipse\workspace\gxclientcpp\gxclientcpp\gxclient\deskband\cwhizzmanager.cpp(348) : {267} normal block at 0x00D97FE0, 4 bytes long.<br />
And the ugly ones, because they DON'T report file/line number  :
<br />
Data: <A 5 0 0 p l u s > 41 00 35 00 30 00 30 00 70 00 6C 00 75 00 73 00 <br />
{460} normal block at 0x00D9F5F8, 32 bytes long.<br />
The funny thing is that the A500plus comes in a character and in an attribute of an XML tag
The Content handler seems to be ok:
<br />
void MyContent::GetSafeValue(wstring &target, ISAXAttributes *attrs, LPTSTR name) {<br />
size_t len1;<br />
int len2;<br />
StringCchLength(name, STRSAFE_MAX_CCH, &len1);<br />
LPTSTR value;<br />
<br />
if (attrs->getValueFromQName(name, len1, &value, &len2) == E_INVALIDARG) {<br />
target = TEXT("");<br />
} else {<br />
target = value;<br />
SysFreeString(value);<br />
}<br />
}<br />
<br />
HRESULT STDMETHODCALLTYPE MyContent::startElement(wchar_t __RPC_FAR *pwchNamespaceUri,<br />
int cchNamespaceUri, wchar_t __RPC_FAR *pwchLocalName,<br />
int cchLocalName, wchar_t __RPC_FAR *pwchRawName,<br />
int cchRawName, ISAXAttributes __RPC_FAR *pAttributes)<br />
{<br />
m_characters.clear();
<br />
if (!wcscmp(pwchRawName, TEXT("response"))) {<br />
wstring boolStr;<br />
<br />
GetSafeValue(boolStr, pAttributes, TEXT("hasPrev"));<br />
<br />
if (!wcscmp(boolStr.c_str(), TEXT("true"))) {<br />
m_hasPrev = TRUE;<br />
} else {<br />
m_hasPrev = FALSE;<br />
}<br />
<br />
GetSafeValue(boolStr, pAttributes, TEXT("hasNext"));<br />
<br />
if (!wcscmp(boolStr.c_str(), TEXT("true"))) {<br />
m_hasNext = TRUE;<br />
} else {<br />
m_hasNext = FALSE;<br />
}<br />
}<br />
return S_OK;<br />
}<br />
<br />
HRESULT STDMETHODCALLTYPE MyContent::characters(wchar_t __RPC_FAR *pwchChars, int cchChars)<br />
{<br />
wstring aux(pwchChars);<br />
m_characters.append(aux.substr(0, cchChars));<br />
return S_OK;<br />
}<br />
Believe me, there seems to be nothing extrange there (no more than the GetSafeValue), and there are no obvious memory leaks (And the file is a little big to post it here)
If any one sees the mistake I would be grateful for ever
Regards, Demián

I have a small function in my app that displays an HTML dialog that works find in Windows XP but not 98. Code is as follows:
<br />
void ShowExportTemplatePreview(HWND hwnd)<br />
{<br />
<br />
HINSTANCE hinstMSHTML = LoadLibrary(TEXT("MSHTML.DLL"));<br />
<br />
if(hinstMSHTML)<br />
{<br />
SHOWHTMLDIALOGFN *pfnShowHTMLDialog;<br />
pfnShowHTMLDialog = (SHOWHTMLDIALOGFN*) GetProcAddress(hinstMSHTML, TEXT("ShowHTMLDialog"));<br />
<br />
if(pfnShowHTMLDialog)<br />
{<br />
char szTemplatePreview[MAX_PATH];<br />
wsprintf(szTemplatePreview, "%s\\Temp_0.html", cStartupData.szAppDirectory);<br />
<br />
WCHAR wcTemplatePreview[MAX_PATH];<br />
<br />
MultiByteToWideChar(CP_THREAD_ACP, NULL, szTemplatePreview, sizeof(szTemplatePreview), <br />
wcTemplatePreview, MAX_PATH);<br />
<br />
IMoniker *pURLMoniker;<br />
CreateURLMoniker(NULL, wcTemplatePreview, &pURLMoniker);<br />
<br />
if (pURLMoniker)<br />
{<br />
BSTR bstrOptions = SysAllocString(L"dialogHeight:30;dialogWidth:45;resizable:yes");<br />
<br />
(*pfnShowHTMLDialog)(hwnd, pURLMoniker, NULL, (char*) bstrOptions, NULL);<br />
<br />
SysFreeString(bstrOptions);<br />
<br />
pURLMoniker->Release();<br />
}<br />
}<br />
<br />
FreeLibrary(hinstMSHTML);<br />
}<br />
}<br />
This is mostly copied from MSDN and I am trying to find compatibility issues with no success. We have pinpointed the problem to:
(*pfnShowHTMLDialog)(hwnd, pURLMoniker, NULL, (char*) bstrOptions, NULL);
But i have no idea as to what is causing the error or how to even go about solving it. Does anyone have any experience with this function that could be of help? Thanks in advance.

You haven't said what the error is?

What problem - besides "not working"?
You aren't testing a) if the file exists, b) whether an appropriate version of MSHTML is being used, c) what ShowHTMLDialog() returns, d) whether the hWnd is valid.
FYI you should use the pre and code links on the Formatting bar below the mssage area when posting code.

GetLastError() returns 0 and I don't know specifically which function to call to get this type of error (I'm very new to this stuff and can't find it in MSDN)
Not working means the dialog isn't opening. The file is there, MSHTML.dll is being loaded as well.
Thanks for the help.

Check your return values and init your pointers to NULL. Specifically, if CreateURLMoniker() fails, you don't look at its retval and pMoniker will be left as uninitialized (but non-zero) garbage, which you will treat as success.
