The headers included in your VC-project have nothing to do with compile errors. Check source files for #include statements. As far as I know, rhessys.h is not a Windows header.
Porting stuff from linux to Windows should (IMHO) be done manually, not with magical tools.

Don't mean to disappoint you, but Unix/Linux code cannot be easily ported from/to Windows, unless
1) the code is trivial (extremely simple), or
2) the code was written in a portable way
Here is a list of most unportable items:
1) GUI
3) Networking
3) IPC
4) Unsupported features
Best,

Hi,
I have a dialog that was previously a child window of another window. This dialog implements a custom control that notifies the parent using by sending custom WM_COMMAND messages.
I want to change this window to be a popup window but to remain a control of the parent dialog.
The problem is that once I change the window's style to popup() the SetDlgCtrlID() function fails.
GetLastError() reports:
1401: Invalid menu handle.
I have tried setting the id using ::SetWindowLong() as well, but I got the same error message.
Is it not possible to make a popup act as a control of another window? I need this control to be flexible enough so that it can be embedded in another window or to float on its own. I would prefer to use the WM_COMMAND message for sending notifications instead of defining a new window message for each notification.
Any help is appreciated.
Thank you,
Tom

Hi.
I have a program that terminates name given process. But it doesn't terminate most of processes. For example terminates calc.exe but doesn't terminate winamp.exe. I think some privilege issue but not sure. Here is my code:
void TerminateProcess(char *szProcToTerminate)
{
hProcessSnap = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, 0 );
pe32.dwSize = sizeof( PROCESSENTRY32 );
if( !Process32First( hProcessSnap, &pe32 ) )
{
CloseHandle( hProcessSnap );
}
char chhh[260];
do{
sprintf(chhh, "%s", pe32.szExeFile);
dwPriorityClass = 0;
hProcess = OpenProcess( PROCESS_ALL_ACCESS, FALSE, pe32.th32ProcessID );
if(stricmp(pe32.szExeFile, szProcToTerminate) == 0)
{
TerminateProcess(hProcess, 0);
}
} while( Process32Next( hProcessSnap, &pe32 ) );
CloseHandle( hProcessSnap );
Refresh();
}
How can i modify this function to terminate "all kind of" processes.

If you know it to be a "privilege issue," then why not adjust the privilege accordingly? Search for:
OpenProcessToken()<br />
LookupPrivilegeValue()<br />
AdjustTokenPrivileges()

It may also be the case that the process is stuck in kernel space, waiting for some object to become signalled? It wouldn't be the first (nor the last) time winamp hung. Does TerminateProcess() return FALSE, and if so, what does GetLastError() return?

I need to develop some control looking like this
please help with some ideas,
i think the best way is to derive a class frow CWnd and inside it make some CStatic controls wich will display images using GDI+, but if you have some expirience or know some doc or place to look at, please post it.
P.S.: I'm beginner in MFC

Probably just write a custom control and paint everything yourself. Windows are rather expensive objects and I don't see why you need so many windows to do something as simple as a BitBlt(). None of the windows common controls use GDI+, only GDI.
The only question I think is whether to extract all the thumbnails when the video is loaded and cache it, or generate and cache them on the fly.
Here's an article on creating custom controls.

Hi fellows
I'm developed an app that generates a xml file with some nodes.
it works file, but a little different thing is occuring: the nodes and the filename are saved with chinese(or japanese, I don't know) characters.
I have a function that transforms a string to BSTR. I've verified if the functions works fine and it works, It doesn't convert to chinese os japanese chars. If I define BSTR in the SaveXML function the nodes are saved correctly.
I think that the problem occurs in my conversion to BSTR, but I'm not 100% certainly.
This is the code:
<br />
void myClass::SaveTheXML()<br />
{<br />
BSTR string; <br />
BSTR theString, theString2; <br />
VARIANT theVar, theVar2; <br />
string = L"teste.xml"; <br />
theString = L"arquivo"; <br />
theString2 = L"valor"; <br />
VariantInit(&theVar); <br />
VariantInit(&theVar2); <br />
V_BSTR(&theVar) = SysAllocString(string); <br />
V_BSTR(&theVar2) = SysAllocString(theString2); <br />
V_VT(&theVar) = VT_BSTR; <br />
V_VT(&theVar2) = VT_BSTR; <br />
parent = CreateXMLElement(sNode1); <br />
child = CreateXMLElement(sNode2); <br />
xmlDocument->createElement(L"primeiro", &parent); <br />
xmlDocument->createElement(L"segundo", &child); <br />
InsertChildNode(parent, child); <br />
InsertChildNode(xmlDocument, parent); <br />
xmlDocument->save(ReturnVariantString(xmlFileName));<br />
}<br />
So, fellows what's going on? Thanks a lot for the support. Below the code that I developed:
<br />
void myClass::InsertChildNode(IXMLDOMNode * parentNode, IXMLDOMNode * childNode) <br />
{ <br />
IXMLDOMNode * localNode = NULL; <br />
handleResult = parentNode->appendChild(childNode, &localNode); <br />
if(localNode == NULL)<br />
{<br />
MessageBox(NULL, "Erro na inserção do node", "Erro", MB_OK|MB_ICONERROR);<br />
return;<br />
}<br />
} <br />
void myClass::SaveTheXML()<br />
{ <br />
string sNode1, sNode2, xmlFileName, sAttribName, sAttribValue; <br />
IXMLDOMAttribute * tempAttribute = NULL; <br />
sNode1 = "primeiro"; <br />
sNode2 = "segundo"; <br />
xmlFileName = "teste.xml"; <br />
sAttribName = "arquivo"; <br />
sAttribValue = "valor"; <br />
parent = CreateXMLElement(sNode1); <br />
child = CreateXMLElement(sNode2); <br />
theAttribute = CreateXMLAttribute(sAttribName, sAttribValue); <br />
child->setAttributeNode(theAttribute, &tempAttribute); <br />
InsertChildNode(xmlDocument, theAttribute); <br />
InsertChildNode(parent, child); <br />
InsertChildNode(xmlDocument, parent); <br />
xmlDocument->save(ReturnVariantString(xmlFileName)); <br />
} <br />
<br />
VARIANT myClass::ReturnVariantString(string sNodeName) <br />
{ <br />
VARIANT variant;<br />
VariantInit(&variant); <br />
V_BSTR(&variant) = SysAllocString(StringToBSTR(sNodeName)); <br />
V_VT(&variant) = VT_BSTR; <br />
return variant; <br />
}<br />
<br />
IXMLDOMElement * myClass::CreateXMLElement(string sNodeName)<br />
{ <br />
IXMLDOMElement * xmlElement = NULL; <br />
BSTR sTemp = StringToBSTR(sNodeName); <br />
handleResult = xmlDocument->createElement(sTemp, &xmlElement); <br />
if(xmlElement == NULL)<br />
{<br />
MessageBox(NULL, "Erro na criação do node", "Erro", MB_OK|MB_ICONERROR); return NULL;<br />
} <br />
return xmlElement;<br />
}<br />
IXMLDOMAttribute * myClass::CreateXMLAttribute(string sAttributeName, string sAttributeValue)<br />
{ <br />
IXMLDOMAttribute * theAttribute = NULL; <br />
xmlDocument->createAttribute(StringToBSTR(sAttributeName), &theAttribute); <br />
handleResult = theAttribute->put_value(ReturnVariantString(sAttributeValue)); <br />
if(handleResult != S_OK)<br />
{<br />
MessageBox(NULL, "Erro na criação do atributo do node", "Erro", MB_OK);return NULL;<br />
} <br />
return theAttribute;<br />
}<br />
<br />
BSTR myClass::StringToBSTR(string sValue)<br />
{<br />
BSTR sTemp = (BSTR)(const char *)sValue.c_str(); <br />
return sTemp;<br />
}<br />

This will give you interesting results at best. The reason is that BSTRs have to be allocated (you haven't allocated anything in this method). A replacement would be:
_bstr_t myClass::StringToBSTR(const std::string& value)
{
_bstr_t bstrValue(value.c_str());
return bstrValue;
}
You can pass _bstr_t's into MSXML's method calls because it overrides the BSTR() operator for you.

Two questions Zac:
1)What's the _bstr_t?Is it a private variable that I must to declare?I tried this and doesn't work.
2)I don't understand this: bstrValue(value.c_str()); What is the bstrValue?
|

_bstr_t is a helper class that Microsoft wrote. Check here for the documentation.
Line by line, the code I wrote does the following:
_bstr_t myClass::StringToBSTR(const std::string& value)
{
_bstr_t bstrValue(value.c_str());
return bstrValue;
}
I believe I forgot the return line in the previous post ... sorry about that.

You are not creating BSTRs correctly - a BSTR is not simply a pointer to an array like a C-style string is. See my string article[^] - look at the "String in COM" section.
Tom make things easier, you could use a wrapper like _bstr_t or CComBSTR.

Hi all,
When i use create() to raise a modeless dialog
the compiler tells me i can't use create() with no arguments.
What is the correct way to do that ?
Thanx in advance,
Desmo16.
|
|
|
|
|
hDlgModeless=CreatDialog(hInstance,szTemplate,hwndParent,DialogProc);
|
|
|
|
|
For either of the methods:
BOOL Create( LPCTSTR lpszTemplateName, CWnd* pParentWnd = NULL );
BOOL Create( UINT nIDTemplate, CWnd* pParentWnd = NULL ); You must specify at least a template name or a template id.

Hey guys,
I tried searching for static unsigned int on Google but I get a lot of gibberish answers.
It would be greatly appreciated if someone can give me a brief description about it because the document im trying to understand is full of static unsigned integers
Thanks

The key here is 'static'. It tells system to allocate memory for the static variable in heap, rather than stack. So the value of the variable can be retrieved globally.
|
|
|
|
|
No, static tells the compiler to allocate the memory in the static memory area. new, malloc, etc, allocate from the heap.
