hi all,
I have made a dialog based application in vc2008...
my problem is when i run my application sometimes it gives an error
Window has triggered a breakpoint in program.
This may be corruption of the heap, which indicates a bug in program or any of the dll it has loaded....
This may also be due to user pressing F12 while Program is in focus.
The output window may have more diagnostic information...
and sometimes it runs fine....
my application runs in release mode so can't debug it....
how can i resolve my problem...

Why cant you run it in debug?
|
|
|
|
|
Run the application in debug mode and read here[^]
You need to google first, if you have "It's urgent please" mentioned in your question.

I have developed a Ribbon application on Vista using VS 2008. It works fine on Vista. I statically link MFC so that I can run it on XP too.
But when I run it on XP, it puts up a dialog box saying "A required resource was unavailble". Later if I press OK on this dialog, it puts up another one saying "Encountered an improper argument". Many such("Encountered an....") dialogs follow(one after another) until I terminate it from the task manager.
Interesting thing I noticed is that this scenario occurs when I just place the mouse pointer over the Ribbon bar. I do nothing else. Then I open the Task manager and see that the memory used is increasing by 8 Kbytes with every second. Eventually followed by the above scenario.

I solved the problem.
There was a resource leak in my code, but it was crashing in MS VC++ code.
I was getting the handle to dc(GetDC()) in some UI update event(ON_UPDATE_COMMAND_UI), but I was not releasing it.

Hi,
I've been searching far and wide on how to setup a client certficate so that my application can access a https server using winhttp.
Ultimate goal
Application uses the https server for storage and updating of personal statistics information. This data can be accessed from any machine with this application, using it's internal memory certficate, eg, the certficate shouldn't be stored in a windows certficate store, user identification is done on protocols internal to the script running on the server address.
Problem
The documentation on how to setup and use a client certifcate (p12) with password for a certificate store, is very poor to non-existent.
If I try to load a p12 certificate through:
m_hCertStore = CertOpenStore(
CERT_STORE_PROV_FILENAME,
X509_ASN_ENCODING | PKCS_7_ASN_ENCODING,
NULL,
0,
L"my-client.p12"
);
The function fails, and as far as I can see, this is the only way to load a certificate for my application to use internally.
As mentioned above the ultimate goal is to have the certificate entirely in memory, but in the meantime it's acceptable to just load it from a file.
Solution?
Can anyone give some pointers on how to use a p12 file or other client certificate setup with a certifcate store?
When i test this same certifcate through IE it asks for the password contained in the file. So I'd imagine I'd have to supply this password through an API to load it into my certficate store, but there's no information how to work with this.
Any advice welcome, I'm completely stumped!!!

You have probably solved this by now, but, here are the key ideas for the client:
Read the .p12 into memory.
Use PFXImportCertStore to put it into a certstore
Use WinHttpSetOption with the WINHTTP_OPTION_CLIENT_CERT_CONTEXT parameter.
HCERTSTORE PFXImportCertStoreTCHAR( CRYPT_DATA_BLOB *PFX, const TCHAR * password )
{
#if defined UNICODE || defined _UNICODE
return ::PFXImportCertStore( PFX, password, 0 );
#endif
// Have to convert char * password to wchar_t *
size_t sizeInWords= 999;
wchar_t wcstr[999];
size_t count= strlen( password );
size_t returnValue;
errno_t err= mbstowcs_s( &returnValue, wcstr, sizeInWords, (const char *)password, count );
return ::PFXImportCertStore( PFX, wcstr, 0 );
}
// Use a .pfx certificate and private key
// Note that the certificate must be associated with a private key to avoid a ERROR_WINHTTP_CLIENT_CERT_NO_PRIVATE_KEY error.
//
void setClientCertificate( const std::vector< unsigned char > & clientPfx, const TCHAR * szPassword )
{
if ( 0 == (openFlags & WINHTTP_FLAG_SECURE) ) return; // No need to send a client certificate if using plain http
// Convert a .pfx or .p12 file image to a Certificate store
CRYPT_DATA_BLOB PFX;
PFX.pbData= (BYTE *)&clientPfx[0];
PFX.cbData= clientPfx.size();
HCERTSTORE pfxStore= PFXImportCertStoreTCHAR( &PFX, szPassword );
if ( NULL == pfxStore ) throw std::pair<int,int>( __LINE__, ::GetLastError() );
// Extract the certificate from the store and pass it to WinHttp
PCCERT_CONTEXT pcontext= NULL, clientCertContext;
while ( pcontext = ::CertEnumCertificatesInStore( pfxStore, pcontext ) ){
clientCertContext= ::CertDuplicateCertificateContext( pcontext ); // CertEnumCertificatesInStore frees its passed in pcontext !
BOOL stat= ::WinHttpSetOption( hRequest, WINHTTP_OPTION_CLIENT_CERT_CONTEXT, (LPVOID)clientCertContext, sizeof(CERT_CONTEXT) );
if ( FALSE == stat ) throw std::pair<int,int>( __LINE__, ::GetLastError() );
return; // Success
}
throw std::pair<int,int>( __LINE__, ::GetLastError() ); // No certificates in the store created from the pfx/p12
}

Hi.
I have an MSI package which works with 2000, XP and Vista Home Premium; after installation, in each case the ShellNew process works perfectly (a right click on the desktop and explorer offers the creation of a new file based on a template which is fully qualified; and life is good). However, under Ultimate the popup menu does not contain the option. I have tried adding the template (removing the qualified path from the Reg ShellNew entry) to the system ShellNew directory, but whatever I do; it simply will not work. Has something changed under Ultimate or is there an additional setting that I need to consider. Any help or comment would be much appreciated.
My best regards, in hopeful and optimistic anticipation.
James.

hi guys,
i been working on a worm scanner lately... i got a funtion that list all the files in a directory.. but the the filename is on vector<wstring> but i need to list them in a list box. but when i compile there is no problem but when i run it there is problem showing :
An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll
Additional information: Input string was not in a correct format.
Below is my coding :
if (ListFiles(directory, L"*", files)) {
for (vector<wstring>::iterator it = files.begin();
it != files.end();
++it) {
std::string filename = WStringToString(it->c_str());;
std::string s=filename;
String ^someString= gcnew String(s.c_str());
listBox1->Items->Add(String::Format(someString,"\n"));
// wcout << it->c_str() << endl;
}
}
Kidly help me plz...
Regards,
Thilek

I suppose you don't need to convert the std::wstring to a std::string before assigning it to a System.String, moreover AFAIK the first argument to String::Format should be the requested format. Anyway you'll eventually get better help in the (Managed) C++/CLI [^] forum.

Why can't you just send the listbox a LB_DIR message?

Hi all,
I'm embarking on a fairly complex project (I know. Please don't say simply "Google for it". I already did).
What I want is to implement an OLE DB layer between a physical DB (connection via standard OLE DB interface) and a client application.
The aim is to implement row level security and additional functions (such as logging) in the OLE DB layer.
So the architecture should be like this (top-down):
Client Application <- Ole DB consumer application (MFC, .NET, Excel...)<br />
-----------------------<br />
OLE DB Provider <- On the client. Dumb connection to my service via the Network layer<br />
-----------------------<br />
<br />
Network layer <- I really don't know how to pass through this<br />
<br />
-----------------------<br />
OLE DB Consumer/Provider service <- This should be on a network server. Here I'm implementing row level security. This service acts as an OLE DB consumer for the DB and exposes data to the client.<br />
-----------------------<br />
Physical DB <- Any OLE DB-compliant database (mainly SQL Server or Oracle)<br />
-----------------------
My question is: what is the best way to implement the Network layer?
I found an OLE DB Remoting Provider by Microsoft, but seems outdated and not supported ATM. If using this, I should implement OLE DB Provider interfaces into the Service on the server.
Any suggestions?

When our application is used on a Japanese system, we are encountering a DBCS problem. When entering text into one of the edit controls, there may be several instances of the shift-out/shift-in pair intermingled with "normal" text. For example:
SoXXXXXXSiXSoXXXXXXSi
When I call GetTextLength() on this text, it returns 13. If this text is saved to a text file (e.g., using Notepad since it's all I can understand on a Japanese system), the size is reported as 13 (I guess the 2 SoSi pair did not get saved). Now for the problem: when I send this text and its length (13) to the AS/400 system for processing, it complains about a mismatched SoSi pair. Debugging on the AS/400 end, we can change the length to 17 and it works fine. I've no clue how to handle this. If the above example were doubled, then GetTextLength() would return 26, yet we'd have to change the value to 34 in order for it to work.
Any clues?

GetTextLength() is returning the length in characters.
How are you determining the number of bytes to write to the file?
For DBCS, length in characters is not the same as length in bytes.

You've considered using Unicode, I assume?
If not, you may have to write your own strlen, hunting from the start to a terminating zero, to get the number of bytes.

I'm not. I just paste the text into Notepad and save it.
Graham Bradshaw wrote: You've considered using Unicode, I assume?
Yes, but I've read nothing thus far that says it would solve the problem. The application is 10+ years old so retooling it for Unicode would be no small undertaking.
