Hi!
How can I use one in Visual BASIC developed DLL in Visual C ++?
This DLL contains several classes which I want to use in mine C ++ program. DLL is registered.
At the moment I do the following:
#import "ConvetHTML2WORD.dll"
using namespace ConvertHTML2WORD;
....
....
....
_CConvertHTML2WORDPtr ptrConvert; //CConvertHTML2WORD is a class from a VB6 DLL
HRESULT hr = ptrConvert.CreateInstance("ConvertHTML2WORD.CConvertHTML2WORD");
//"ConvertHTML2WORD.CConvertHTML2WORD" is a registry key in the registry
The CreateInstance does not function.
ptrConvert it remains NULL
what do I do to wrong?
Thnks, Nikolai

What's the value of hr?
If you use the hr format in the Watch window (type hr,hr) the debugger will convert to the symbolic name for you.

hello
I have a little problem with a dll
I am tying to hook some processes with a variable in a dll.
The variable should hold the names of all the path for the hooked processes. I have shared the variable everything is OK but when I try to initialize it from a file (because I read the entryies from a file) the callback function for the hook runs wild and I do not get the correct modulefilenames. All I get is my program's module filename.
I was wondering what is wrong.
here is a piece of code:
//globals
struct pr<br />
{<br />
char nume[1024];<br />
};<br />
<br />
#pragma data_seg("SHARED")<br />
HHOOK cbt=0;<br />
pr procs[100];<br />
int cnt=0;<br />
#pragma data_seg()<br />
#pragma comment(linker, "/section:SHARED,RWS")<br />
<br />
<br />
LRESULT CALLBACK CallWndProc(int nCode,WPARAM wParam,LPARAM lParam)<br />
{<br />
<br />
if (nCode<0)<br />
return CallNextHookEx(cbt,nCode,wParam,lParam);<br />
<br />
CWPSTRUCT *wps = (CWPSTRUCT*)lParam;<br />
<br />
<br />
DWORD pid;<br />
GetWindowThreadProcessId((HWND)wps->hwnd,&pid);<br />
HANDLE hProc;<br />
hProc=OpenProcess(PROCESS_ALL_ACCESS,FALSE,pid);<br />
HMODULE mods[100];<br />
DWORD size;<br />
char nume[1024];<br />
<br />
<br />
if (EnumProcessModules(hProc,mods,sizeof(mods),&size))<br />
if (size>0)<br />
GetModuleFileNameEx(hProc,mods[0],nume,sizeof(nume));<br />
<br />
<br />
<br />
CreateMutex(0,0,"Pula");<br />
if (GetLastError()!=ERROR_ALREADY_EXISTS)<br />
{<br />
CreateMutex(0,0,"Pula");<br />
FILE *str;<br />
char temp[1024];<br />
GetTempPath(sizeof(temp),temp);<br />
strcat(temp,"\\IdleProcesses.sys");<br />
str=fopen(temp,"a+");<br />
int i;<br />
i=0;<br />
while(!feof(str))<br />
{<br />
i++;<br />
fgets(temp,sizeof(temp),str);<br />
temp[strlen(temp)-1]='\0';<br />
strcpy(procs[i].nume,temp);<br />
<br />
}<br />
fclose(str);<br />
cnt=i;<br />
}<br />
<br />
<br />
<br />
<br />
for (int i=1; i<=cnt; i++)<br />
<br />
<br />
if (StrStrI(nume,procs[i].nume)!=NULL)<br />
{<br />
DWORD exit;<br />
GetExitCodeProcess(hProc,&exit);<br />
TerminateProcess(hProc,exit);<br />
}<br />
<br />
<br />
return CallNextHookEx(cbt,nCode,wParam,lParam);<br />

Hello,
I am working with tab controls and I would like to know if when a user selects a tab if you also have to hide the other tabs?
In my example there are two tabs here is the code that i am using the for loop works the code below the for loop does not. the only difference i can see is that in the for loop code i am hiding and showing and the code further down is only showing. does anyone have any comments or suggestions?
TCITEM tcItem;
for(int i = 0; i < m_TabCtrl.GetItemCount(); i++)
{
if (i != m_TabCtrl.GetCurSel())
{
m_TabCtrl.GetItem(i, &tcItem);
m_pDlg = (CMyDlg*) tcItem.lParam;
m_pDlg->ShowWindow(SW_HIDE);
}
}
m_TabCtrl.GetItem(m_TabCtrl.GetCurSel(), &tcItem);
m_pDlg = (CMyDlg*) tcItem.lParam;
m_pDlg->ShowWindow(SW_SHOW);
*pResult = 0;
}
// THIS CODE DOES NOT WORK IT IS SUCCESSFUL IN GETTING THE HWND BUT IT DOES NOT PROPERLY HIDE AND SHOW. I AM CURIOUS TO KNOW WHY I DIDN'T THINK THAT IT WAS NECESSARY TO HIDE THE WINDOWS AS WELL BUT I AM BEGINNING TO THINK THAT IT IS NECESSARY BECAUSE THAT IS WHAT THE CODE ABOVE DOES?
int Index = m_TabCtrl.GetCurSel();
m_TabCtrl.GetItem(Index, &tcItem);
CMyDlg* pDlg = (CMyDlg*) tcItem.lParam;
pDlg->ShowWindow(SW_SHOW);
Thanks,
Lino

Is it possible to use Visual Studio .Net (7.1) for the generation of Web pages, or is it much better to use something like DreamWeaver. The pages will have quite a bit of I/O controls in them; e.g. buttons, edit boxes etc.
Someone said that you can edit html files (and asp files) in Visual Studio.
I did have a look, but what type of project do you specify if it is possible to have a series of Web pages as a project.
Also whats the difference between html and asp files and does it matter what you use in Visual Studio.

SetMapMode (hdc, MM_ISOTROPIC) ;
SetWindowExtEx (hdc, 276, 72, NULL) ;
SetViewportExtEx (hdc, cxClient, cyClient, NULL) ;
SetWindowOrgEx (hdc, 138, 36, NULL) ;
SetViewportOrgEx (hdc, cxClient / 2, cyClient / 2, NULL) ;
Can anybody gives me a fully step by step explanation about the codes above, why the logical point (0,0) become the way it is?
Or give me a link to resources that can clarify the "SetWindowExtEx,SetWindowExtEx, SetWindowOrgEx,, SetViewportOrgEx" in much easy understanding way?These problem really bother me a lot!

there are too many #endif ...
you need to have one #endif per #if ( or #ifdef or #ifndef )
at the end you should have something like :
#ifdef __cplusplus
}

Then how do source code and resource hackers work...? V.G

Resource 'hacking' is a different story. Windows has a defined interface (UpdateResource[^]) for modifying resources in executables.

 do u seen any s/w which reveal you source code of application ?
if this possible, then new MSCP Window is coming next month  ?
yeah it possible to to hack resource, UpdateResource api will help,but it's work on Win2000 and above plateform only

For compiled C++ programs, this isn't generally possible. The compiler translates C++ source code into machine language. The resulting machine language does not contain sufficient information (at least in code compiled for release) to reconstruct the original source.
For .NET programs, compiled into IL, I believe it is possible to decompile those programs.

Hi guys,
I am developing a program that replaces executables icons with icons from other applications (executables) or from icon files. For now I am using this code in order to do it:
<br />
HMODULE hLibrary;<br />
HRSRC hResource;<br />
HGLOBAL hResourceLoaded;<br />
LPBYTE lpBuffer;<br />
HICON hIcon;<br />
int skip=0;<br />
<br />
hLibrary = LoadLibrary(icon);<br />
if((int) ExtractIcon(AfxGetInstanceHandle(), icon, (UINT) -1))<br />
for(unsigned long n=0;n<=1000000;n++)<br />
{<br />
hResource = FindResource(hLibrary,MAKEINTRESOURCE(n), RT_ICON);<br />
if(hResource)<br />
if(skip==IconIndex)<br />
n=1000001;<br />
else<br />
skip++;<br />
}<br />
else<br />
MessageBox("The icon file or the first file contains no icon");<br />
if(hResource)<br />
{<br />
hResourceLoaded = LoadResource(hLibrary,hResource);<br />
lpBuffer = (LPBYTE) LockResource(hResourceLoaded); <br />
hIcon=CreateIconFromResource((PBYTE)lpBuffer,SizeofResource(hLibrary,hResource),1,0x00030000);<br />
<br />
HANDLE hUpd=BeginUpdateResource(my_name,0);<br />
UpdateResource((HMODULE)hUpd,RT_ICON,MAKEINTRESOURCE(1),MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),lpBuffer,SizeofResource(hLibrary,hResource));<br />
EndUpdateResource(hUpd, FALSE);<br />
}<br />
FreeLibrary(hLibrary);<br />
So now I am using LoadLibrary, FindResource, LockResource to extract icon from executable or dll and then I use UpdateResource(...) to write icon to new exe. The problem is that this options does not suport icon files (.ico) and also it doesn't allow the user to extract the specified icon. I am using ExtractIcon() to get icon number.
Another way, more efficient and better would be to use ExtractIcon() to get icon form exe, dll or ico file. The problem of this mettod is that ExtractIcon() does not return a pointer to the data to be written by UpdateResource(...) instead it returns a HICON handle.
My question is how could I write this HICON handle to the new exe using UpdateResource(...). Itried several different methods but achieved one worked?
Please help anyone, this is very important to me.
Thanks.

Hi,
What I need to do is schedule some files to be deleted either at shutdown or at startup. My application can't do this because it is closing after it creates them and they need to remain there until shutdown. My app is currentlly creatting bat files for each of them and adds them to Startup folder in Start Menu. This method is inneficient though. For example how do uninstallers delete their executable at shutdown (startup)???
Thanks,
Andrew
