how to let all contents tabs of html-help expand when the htmp-file pops up by HtmpHelp(...) function?
it can be done in html-help design or c++ code.
I did see some apps with contents tabs expended when apps' html-help pop up.
thx.

I have one source code of project in which our dll is used that source code is not full source code the client give us obj file instead of cpp and we fix bugs of our dll now linking error occur when i execute that program with new dll. pls help me if anybody have any idea.
Thanks in advance

Maybe (i.e. post error messages for meaningful help) you have changed function signatures.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

No i dont change any function signature ,i just fix bugs only. the problem is that as i learn .obj is only compiled file and it is not linked with library when we execute our porgram than it link with library and gives executable file. (.exe ).but in my case it give linking error.

the .obj contains the necessary info to perform the function calls to your DLL at runtime hence, if you're stuck with original signatures (and exports) then you shouldn't experience problems. BTW Why don't you post the error message?

OK, to summarize, all the info I got from you, are: "I fixed bugs". Hence, all that I can deduce is that your executable works fine, congratulations!

I am writing the following code for creating the XML file.
HRESULT hr;
IXMLDOMDocumentPtr pXMLDoc = NULL;
CoInitialize(NULL);
hr=pXMLDoc.CreateInstance("msxml2.domdocument");
IXMLDOMNodePtr pRootNode= NULL;
IXMLDOMNodePtr pRecNode= NULL;
IXMLDOMNodePtr pRecNode1= NULL;
IXMLDOMElementPtr pElement=NULL;
_variant_t varNodeType((short)MSXML2::NODE_ELEMENT);
hr= pXMLDoc->createNode(varNodeType,
_T("RTCS"), _T("Remote Target Control System"),&pRootNode);
hr=pXMLDoc->createElement(_T("Connection"),&pElement);
IXMLDOMAttributePtr pRecIdAttr = NULL;
IXMLDOMNamedNodeMapPtr pattributeMap;
hr=pXMLDoc->createAttribute(_T("connect"),&pRecIdAttr);
hr=pRecIdAttr->put_nodeTypedValue(_variant_t(_T("connect_val")));
hr=pElement->get_attributes(&pattributeMap);
hr=pattributeMap->setNamedItem(pRecIdAttr,&pRecNode);
hr=pXMLDoc->appendChild(pRootNode,&pRecNode);
but i am not able to see the child node created in the xml file.Only root node is created:
The xml file i want to create is:
?xml version="1.0"?>
<rtcs name="Remote Target Control System">
<Connection connect= "connectval" ipaddress = "ip_addresss" Port = "port_number"/>
<Logging Directory="path" Level="level" ComPort="port_number" Maxsize="max_size"/>
<Video BitRate="bitrate" InputType="input_type" Preview="preview" FrameDrop="frame_drop" Dumping ="dump"/>
<IR directory_path="dir_path"/>
</rtcs

If you are CREATING an entire XML file, why not do it using string classes instead of all that messy COM stuff ?
Why on earth do you bother to grab the HRESULT returned, if you never check it ?

Hi
In my VC 6.0 programme I used Sqlserver with ODBC connection.
Connection and the retrieving data from the Server was ok.
But initially when I executing it ask for the Server login and password for the Sql Server.
Can any tell me about giving the Sql Server login id and password through Coding itself.
(In programme I used CDatabase, CRecordset)
Awaiting for your suggestion of this.
Regards

Here below is the code snippet to directly give uid and pwd
#define CONNECT_STRING _T("DSN=xxxxxxxxxxx;UID=cccccccc; PWD=ccccccccccc")
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);
.......................
But with this way, you can not change your database password, with out rebuilding the application. The best way is to add two fields (uid and pwd) in the registry and read it from there. With this you can change uid and pwd with out rebuilding the application. But you need to encrypt the uid and password in the system registry, else any one can hack it.

Hello everyone,
If I want to convert LPCTSTR and HRESULT to standard C/C++ data type (like char*, int, long, etc.), I am wondering what standard data types should I convert to be safe and do not lose and data precise?
thanks in advance,
George

|
|
|

Thanks Shilpi,
I found from winnt.h that HRESULT is defined to long. But I can not find the definition of LPCTSTR. Could you find it out?
regards,
George

For unicode it is CONST WCHAR *
and for latin CONST CHAR *
i think now it is helpful for u.
long pointer to null terminated string
LPCSTR Pointer to a constant null-terminated string of 8-bit Windows (ANSI) characters. For more information, see Character Sets Used By Fonts.
This type is declared in WinNT.h as follows:
typedef __nullterminated CONST CHAR *LPCSTR;
LPCWSTR Pointer to a constant null-terminated string of 16-bit Unicode characters. For more information, see Character Sets Used By Fonts.
This type is declared in WinNT.h as follows:
typedef CONST WCHAR *LPCWSTR;
LPCTSTR An LPCWSTR if UNICODE is defined, an LPCSTR otherwise.
This type is declared in WinNT.h as follows:
#ifdef UNICODE
typedef LPCWSTR LPCTSTR;
#else
typedef LPCSTR LPCTSTR;
#endif

Thanks Shilpi,
I do not know it is const before, so I can not change the value of the string, right?
What means long pointer (for 1st letter L in LPCTSTR)?
regards,
George
