Where should I check this? If this is supposed to be in my code,

In your stdafx.h file.. it is self generated according to vc version you are using

Well, I finally got the project to compile. I had to add the typedef struct for _WLX_NOTIFICATION_INFO and PFNMSGECALLBACK in order for it to compile without errors. But now my question is why doesn't it work? I have compiled the following code, and copied newNotif.exp and newNotif.dll to C:\Windows\System32\ and added the below registry entry to my registry. When I reboot, it doesn't do anything, not even the messagebox is displayed.

Hi guys~ I need to build a 3D map system that will accept 2 inputs from users (the current location and the destination user wants to go), by clicking, then the system will generate a path from the current location to the destination.
At first I planed to use OpenGL to do so....but I faced one problem. The exporter that I used can only extract the vertices of the model I built in 3DsMax, not included the texture mapping! I already done nice mapping in 3DsMax and I think it takes time to do mapping in OpenGL.(total up 15 buildings need to be mapped)
Therefore, I switch to VRML (because the 3DsMax can export the model to VRML file with texture mapped)but I found VRML is dead and not powerful at all. Then I switch to Java3D but I heard someone says this programming is dying and will run slow! The most powerful tools for 3D Graphics Application still belongs to--->OpenGL!! And now I stuck here~Time passed away quickly and I still not yet done my system!
I need some help from you guys and suggestions, advices from you all~Please...please help~~~~sob sob////
I more familiar with OpenGL if compared with Java3D and VRML(both I learned 3 days ago only,very unfamiliar~)
I wish to extract the model(with texture mapped) to OpenGl then I can quickly concerntrate on my system(my due date for this project is coming soon)

Thanks a lot!

I think perhaps http://www.wotsit.org is helpful for you

Thanks Thanks Thanks....
I believe that site will help me out a lot. Big Grin | :-D

check out http://www.openscenegraph.org/[^]

All the power of OpenGL, all the ease of higher level operation.

Sir,

I amd Suresh Kumar want to know the differences between the VC++ and .Net. Please send me the differences I request. I referred many books but i didn't get any information regarding this and also searched on internet in many sites
including Microsoft.

Regards,

S.Suresh Kumar

WHat type information are you looking for?

f:\installation\vc98\include\xmemory(37) : warning C4100: '_P' : unreferenced formal parameter
f:\installation\vc98\include\xmemory(68) : see reference to function template instantiation 'void __cdecl std::_Destroy(unsigned int *)' being compiled
Error.cpp

I also got this error. It seems that it caused by the include header. How can i solve this?
Thanks again.

That is only a warning so you don't have to fix anything. The warning says that the function std::_Destroy(unsigned int *) did not use the one parameter.

unexpected end of file while looking for precompiled header directive

i have this error when i compile my project on debug mode but when i compile it in release mode it doesn't have this problem. Please help me. i don't know how to debug this and how come the error occurs when I compile it in debug mode and not when I compile it in release mode. What probably is the cause? Does it mean that i have a missing file? I'm new to Visual C++ Programming.

Put this at the top of every cpp file:

#include "stdafx.h"

John

-- modified at 21:25 Friday 10th March, 2006

i did what you have suggested. It resulted to another error. here it is:

fatal error C1853: 'Debug/CMMITool.pch' is not a precompiled header file created with this compiler

the file which i included the stdafx.h header file is a C source file. this must have caused the other error.

Delete Debug/CMMITool.pch and try again. A pch file may not be used on two different versions of VC++.

John

delete Debug directory, and delete .clw, .opt, .NCB files.
then compile again.

I am writing BHO for now, which dynamically changes the document.

I faced that thing, that if I do next (after the 'documentcomplete' event in browser)

//Code:
CComQIPtr<IHTMLElement> piSpanElement;
hr = pHtmlDocument->createElement(L"span", &piSpanElement);
BSTR innerHtml = L" <u>This is string with leading space"</u>";
//leading space is happily ignored, when I'm inserting that text:

hr = piSpanElement->put_innerHTML(innerHtml);

//Ok-ok, I beleive, it is with the good intentions
//of MSHTML, I will try to insert some text...
//I even do not put a whitespace there...

//Ok, I will try to insert some text...
//(In MSDN it is said, that InsertAdjancedText inserts plain text.

hr = piSpanElement->insertAdjacentText(L"beforeEnd",L"Some text");

//OK, text is in element, but... I needed before content, ok, mistake - I try to correct:

hr = piSpanElement->insertAdjacentText(L"afterBegin",L"!I WANNA SEE THIS TEXT IN ELEMENT before content!");

//It does return S_OK... I do not see that text, WTH!?
//I insert this element simply querying interface and
//substituting the DOM node. After that html element tortures.

May be I'm "stupido", but I cannot convert IHTMLDomNode element to the IHTMLElement. If there is any method - please tell..

then - one more...
we have "this node", reference node, and node to substitute
Substituting node is IHTMLDomNode pointer, former IHTMLDOMTextNode with text " " or any other - the result was same.

CComQIPtr<IHTMLDomNode> resultNode;
VARIANT refNode;

refNode.vt = VT_DISPATCH;
refNode.pdispVal = rNode; //reference node pointer

hr = thisNode->get_parentNode(&pNode); //parent node pointer
//OK, pNode is not null.
hr = pNode->InsertBefore(substitutingNode,refNode,&newNode);
//Why hr is EINVALIDARG???

or just simply - is there any way to insert that eaten leaded space.

Or what I do incorrectly?

1) You should NOT use unicode strings in place of BSTR's. Use SysAllocString() and SysFreeString(). Or better yet, use ATL::CComBSTR.

2) Use QueryInterface() to get IHTMLElement from IHTMLDOMNode. Or better yet use ATL::CComQIPtr<IHTMLElement> spIHTMLElement(piHTMLDOMNode). This calls QueryInterface() automatically.

3) You should NOT use raw VARIANT. Use VariantInit(), VariantChangeType(), and VariantClear(). Better yet, use ATL::CComVariant.

Problems:
QueryInterface() returns null and E_NOINTERFACE (or smth like).
So it seems to me, that the circle closed...
If somebody know, howto do that, please answer

Hello!

Which version of VC++ are you using?
For most applications, they will have dependency on the C Run-time dlls.

In VC++ 2003 and earlier, those CRT dlls are dropped to system32 folder and they just need to be on the path. You can figure out the names of the dlls by using depends.exe.

In VC++ 2005, the CRT dlls are now distributed through Msms that needs to be merged into an Msi to get installed on the user's machine. You can search for VCRedist.exe on the microsoft website. Again - depends.exe should help you figure out those dlls.

hi guys,

im using ReadProcessMemory to read out 4 bytes of a process. The value is a DWORD. Yesterday a friend said to that I should use a Pointer opperation to read out the memory. I read a bit about Pointer and Memory allocation but i didn´t get it working.

I tried this:

DWORD dwAddress = 0x01234567;
DWORD *dwValue = *(DWORD*)dwAddress; // got the address of dwAddress

DWORD dwValue = *(&dwAddress); // got the address ( 0x01234567 )

How can i read out the value ?
