I assume you mean this?
int a, b;
const char* buffer = "90";
sscanf(buffer, "%d", &a);
sscanf(buffer, "%d", &b);
Or if you really want to use dynamically allocated memory (I wouldn't):
int *ptr = malloc(sizeof(int)*2);
const char* buffer = "90";
sscanf(buffer, "%d", &ptr[0]);
sscanf(buffer, "%d", &ptr[1]);

Well friends,
I have actually a function which takes an input an int** ptr and allocates a memory.
void function( int**ptr)
{
*ptr=(int*)malloc(sizeof(int)*2);
char* buffer="90";
sscanf(buffer,"%d",(*ptr)[0]);
sscanf(buffer,"%d",(*ptr)[1]);
}
int main()
{
int*ptr;
function(&ptr);
return 1;
}

Hi,
I want to access the data of node "sequence" and "prompt" in following DOM XML.
<br />
BSTR bstrResponse = SysAllocString( L"<Item>"<br />
L"<serviceProvider>Test</serviceProvider>"<br />
L"<scanSerialNumberPrompt>"<br />
L"<sequence>1</sequence>"<br />
L"<prompt>Serial Number</prompt>"<br />
L"</scanSerialNumberPrompt>"<br />
L"</Item>");<br />
I am using the following code
<br />
MSXML2::IXMLDOMNodePtr pNodeItem = NULL;<br />
MSXML2::IXMLDOMNodePtr pNode = NULL;<br />
MSXML2::IXMLDOMNodePtr CurrentChildNode = NULL;<br />
MSXML2::IXMLDOMNodePtr CurrentNode = NULL;<br />
pNodeItem = CurrentNode->selectSingleNode("serviceProvider"); <br />
pNodeItem =CurrentNode->selectSingleNode("scanSerialNumberPrompt");<br />
for (CurrentChildNode=pNodeItem->firstChild; CurrentChildNode!=NULL; CurrentChildNode = CurrentChildNode->nextSibling)<br />
{ <br />
pNode = CurrentChildNode->selectSingleNode("sequence");<br />
pNode = CurrentChildNode->selectSingleNode("prompt");<br />
}<br />
I am getting the null value in "pNode". Can you please let me know what is the error in accessing the child node in DOM XML.
Thanks

I would do it a bit differently:
....
....
pNodeItem =CurrentNode->selectSingleNode("scanSerialNumberPrompt");
if (NULL != pNodeItem)
{
MSXML::IXMLDOMNodeListPtr pXMLNodeList = pNodeItem->selectNodes(_T("sequence"));
if (NULL != pXMLNodeList)
{
MSXML::IXMLDOMNodePtr pXmlNode = NULL;
for(int i = 0; i < pXMLNodeList->length; i++)
{
pXMLNode = pXMLNodeList->nextNode();
if(pXMLNode)
{
_bstr_t bsTxt = pXMLNode->getText();
........
Do what ever you want with the text here
........
}
}
}
}
same thing for "prompt"
Hope this helps you

Thank you very much Yaron!! your solution is working fine. I wish, I could got the exact problem of my code too.

Hi
I am making an application where I need DDK and I started with a dialog based application in which only include ntddk.h file
Here I am having a problrm, when I include NTDDK.H then it gives error as folloews:

It looks as though you are missing some .h file. I've not dealt with device drivers so I can't offer any suggestions as to which one. Perhaps this search will help.

The last error highlights the problem. You need to specify which architecture you are compiling for - which processor you are targetting for the driver. The other errors are because you haven't specified the architecture. Have a look are the lines surrounding the #error directive to see what your options are.

Hi Ryan
Infact I didnot program for DDK yet before, So Please tell me that how to specify which architecture I am compling ,
Please note that I am making a console based application using VC++ 6.0.
Please guide me.
Thanks

Have a look at the line that's causing the #error (line 10342 of ntddk.h) and see what is causing the #error. I haven't programmed for the DDK in a long time, so I can't remember how to set the architecture. I'm sure Google or MSDN search will help.

Increase the size of Static Text Control

"Increase the size of Static Text Control "
Yes I did it, and i saw that Text when i design,
But when i compile my program, the compiler display a warning :
"title string too long; truncated at 256"
and then i runed my program,:
only 256 first character is displayed.
Why ???
|
|
|
|
|
i think that 256 character limit is due to the resource editor, not to the abilities of the static control itself.
try setting the text with m_myStaticControl.SetWindowText("...");

you can change font from static control
|
|
|
|
|
you wrote"you can change font from static control"
how to do that ?
could you tell me step by step ?
|
|
|
|
|
you can declare one font with createfont
and then assign this font to control
in this parameter from createfont you can set size from font

I have developed an application in C++, and it's time to deploy it. I am using Visual Studio 2003 setup project to deploy it. It's easy to create a simple setup, but customizing the setup is a nightmare, for example, to add a page that displays a log that is generated by an external application that is run during the installation.
During uninstallation, it says that I should close MSN messenger, Windows Messenger and Notepad before uninstalling.
Remove Previous Version also does not work consistently, sometimes, it removes the previous version automatically, at other times, it just gives a messagebox telling that I should remove the earlier version from the control panel.
Am I missing something or are these bugs that you have encountered earlier?
Also, the documentation for setup projects seems to be limited. Could you point me to some good articles on creating setup projects with a fair level of customization?

I have been using Inno setup for other projects and am happy with it. But for this case, I need to include merge modules into the setup, which, I do not think, is possible with Inno setup. That is why I resorted to the Visual Studio setup in the first place.

Hello together,
I have a problem with a Memo-Field or a Binary-Field in Access.
In the Release-Version all is OK, but in the Debug-Version (VisualStudio 5) the comparison of the two pointers (look at the code) failed.
<br />
void AFXAPI AfxLoadField(CRecordset& rs, UINT nField,<br />
void* pvField, long* plLength)<br />
{<br />
CFieldInfo* pInfo = &rs.m_rgFieldInfos[nField - 1];<br />
<br />
rs.SetFieldStatus(nField - 1, pInfo->m_bStatus);<br />
<br />
if (!rs.IsFieldStatusNull(nField - 1))<br />
{<br />
if (pInfo->m_nDataType == AFX_RFX_BOOL ||<br />
pInfo->m_nDataType == AFX_RFX_BYTE ||<br />
pInfo->m_nDataType == AFX_RFX_INT ||<br />
pInfo->m_nDataType == AFX_RFX_LONG ||<br />
pInfo->m_nDataType == AFX_RFX_SINGLE)<br />
{<br />
AfxCopyValueByRef(&pInfo->m_pvDataCache, pvField,<br />
plLength, pInfo->m_nDataType);<br />
}<br />
else<br />
{<br />
AfxCopyValueByRef(pInfo->m_pvDataCache, pvField,<br />
plLength, pInfo->m_nDataType);<br />
}<br />
}<br />
else<br />
*plLength = SQL_NULL_DATA;<br />
<br />
#ifdef _DEBUG<br />
if (pInfo->m_nDataType == AFX_RFX_BINARY)<br />
{<br />
pvField = ((CByteArray*)pvField)->GetData();<br />
}<br />
<br />
if (pInfo->m_pvBindAddress != pvField)
{<br />
TRACE1("Error: field address (column %u) has changed!\n",<br />
nField);<br />
ASSERT(FALSE);
}<br />
#endif // _DEBUG<br />
}
This is the Problem:
AfxCopyValueByRef(&pInfo->m_pvDataCache, pvField,<br />
plLength, pInfo->m_nDataType);
My Code:
RFX_Binary(pFX, _T("[Polygon]"), m_Polygon, 65536);
m_Polygon is the CByteArray.
By AfxCopyValueByRef the pointer pvField sometimes change the adress.
pvField is a pointer on the CByteArray.
Can someone help me ???
