Dear Antri,

Thanks for your prompt reply. My email is coolcool883@hotmail.com.

Is there any alternative if I have to provide progress information to user?

For parameter passing, if I have to pass an array of 10 elements each of which is a fixed length 80 byte string. How should I define in my VB and how can I update the array element in my C program?

Thanks for your kind help.

Regards,
wavewave

'to define the Usertype Array:

Public Type MyArray
String1 As String * 81 ' : array[1..81] of char; // 80 byte string
String2 As String * 11 ' : array[1..11] of char; // 10 byte string
end type

dim MyRecord as MyArray

'to define the dll-function in vba:

Declare Function MyCppDLL Lib "CppTest.dll" Alias "FirstFunctionName" (MyRecord As MyArray) As Byte

'in c++ define the same record with struct.... and you can access the strings (char String[n]) stored in the UserRecord (struct)

String[01] of 255 bytes
String[02] of 255 bytes
String[03] of 255 bytes
:

String[25] of 255 bytes

Thank you.

How to use this API to get the info of remote machines? Here is my sample code.. I am getting a memory error . Can anyone suggest me where i went wrong. Is there any other way to pass the first argument(machine name) to the API?

////////////////////
//getting details of machines
wchar_t *tmp4=(wchar_t *)malloc(sizeof( wchar_t ));
strcat(mbstr2,tempname[snum]);
mbstr2[strlen(mbstr2)]='\0';
size_t x=strlen(mbstr2);
mbstowcs(tmp4,mbstr2,x);
WKSTA_INFO_101 *level=NULL;
LPTSTR tmp7=(LPTSTR)tmp4;

NET_API_STATUS nwData=NetWkstaGetInfo(tmp7,101,(LPBYTE*)&level);

if(nwData==NERR_Success)
{
int iLen3=wcslen ((unsigned short *)level->wki101_computername);
for(int j=0;j<ilen3;j++)
{
="" name[j]="*(level-">wki101_computername);
level->wki101_computername++;
level->wki101_computername++;

I don't understand all that string manipulation at the beginning. Confused | :confused:

The first param is either NULL to use the local computer, or a Unicode string holding the name of the computer to get info for, for example L"\\Servername"

I want to give the first argument at run time(not a NULL value),means give the selected machine name from a list box or edit box. The initial string manipulations were used to convert the value in a CString variable to the type of the first parameter . is it not required? Kidly help..

Use the T2CW macro to do that

#include <atlconv.h> // need this header for the macro
 
{
USES_CONVERSION;
 
  NetWkstaGetInfo ( T2CW(LPCTSTR(sComputerName)), ... );
}

CHtmlView from a DLL

Hi, I am writing an application that has plugins (DLLs). Each DLL has a child window that resides in the application's main dialog window. Some of the plugins need to use web services, however, when I attempt to use the CHtmlView in the child window of the DLL, I crash and burn every time. If I move the same code to the master program, it works.

I tried modifying the DLL to have it's own dialog window, and still both CHtmlView and even the ActiveX MS WebBrowser control do not work. They crash on initialization of the child dialog (dialog never even gets created). This leads me to believe it isn't the child dialog that is the problem, it is DLL + HtmlView = boom....

Has anyone had any success with this type of thing?
Thanks in advance!!

Hey all,

Figured it out. In case you ever run into this problem, the solution is to not only call AfxEnableControlContainer() from your DLL's InitInstance(), but you must also first call CoInitialize(NULL) as well. Smile | :)

Actually, I figured it out. There is an "Adobe Photoshop SDK" on the Adobe Photoshop CD (Version 6.0 and earlier -- apparently they started charging for it in Version 7.0).

How can I get rid of the black line drawn at the bottom of a tab control? None of the options on the property pages seem to do it without adding other lines in places i don't want, and i don't see any member functions that would do it. I want a control that has the dialog face color on its bottom edge (like a typical property page tab set), not black.

if you meant this:

void CMyTab::OnNcPaint() 
{
   CDC *pDC = GetDC();
   CRect cr;
   GetClientRect(cr);

   FrameRect(pDC->m_hDC, cr, ::GetSysColorBrush(COLOR_3DFACE));
   ReleaseDC(pDC);
}

then, no. that's not it. the border is still there.

I'm looking for a way to change the IP address of my computer through an application and testing to make sure there is no network conflict, ect. Can anyone point me to a good resource to figure this out? Thanks

Are you asking how to change it programatically, or are you just wanting to change the ip?

You can use ipconfig from the command line to change network settings pretty quickly, but I am not sure if that is what you are asking for.

Could you clarify what you want to do please?

They don't leak in W2000/XP. In W 95/98/ME, you'll find you suddenly can't draw any thing, nor can the system. MSDN mag ran a tool that showed the number of resources used and allowed you to browse them, a couple of years ago I think.

They leak every where, but WinNT/Win2000,WinXP system are use 32bit vales for addressing up to 2^32 GDI objects while 9x system uses just 16bit values, thus can hold only 2^16, which is much fewer. However that does not mean you can use the whole 4 billion GDI objects in WinNT systems, still the system put an upper limit but I do not know it exaclty, but I did encounter resource leak in WinXP before.

check this MSDN article
http://msdn.microsoft.com/msdnmag/issues/01/03/leaks/default.aspx

Anyway, to detect resource leaks in Win2000/WinXP just open the task manger and go to the processes tab, then from from the "View" menu choose "Select Columns..." the check "GDI Objects". After that look up your process from the system processes and monitor its GDI Object, if they constantly increase then you have a leak, if it increase then stop increasing then it could just be initial allocations.

CObArray.copy ???

Here my special problem:

I have a class CBauteil (derived from CObject) and an CObArray.
CBauteil has although Array with an CObject Class (CBauteilschicht).

exp.

class CDoc : public CDocument

{
public:
CObArray m_oaBauteil;
...}

_________________________________________________

class CBauteil : public CObject

{
public:
CObArray m_oaBauteilSchicht;
...}

_________________________________________________

//Acces to first (filled) array
CBauteil *pBauteil = (CBauteil*) pDoc->m_oaBauteil[0];

//Pointer to second ObArray (m_oaBauteilschicht)
pBauteil->m_oaBauteilschicht

//Now I add a new entry to the first Array
CBauteil *pNeuBauteil = new CBauteil();
pDoc->m_oaBauteil.Add(pNeuBauteil );

//and now I want to copy the first Entry of the "SubArray"
pNewBauteil->m_oaBauteilSchicht.Copy(pBauteil->m_oaBauteilschicht);

The Problem:
When I change a value in the original Array m_oaBauteilSchicht[0] the value in m_oaBauteilSchicht[1] changes although. How can I get a real copy so that I can change the values seperately?

allocate a new CBauteil object. copy the data from your 'source' object. add the new object to the second array.

Drawing ( CView )

Hello,

I have a VC++6(MFC) Application which is giving me a problem in Windows98/ME, but not on XP or 2000. The App has a CView that I use to draw on the screen OnDraw(CDC* pDC). I read information for an access database using ado and from that information I draw a chart on the screen. It runs five on XP/2000 but on 98 after a while or many call to the OnDraw functions it freezes and all the bitmaps that I am drawing on the screen don’t show anymore when I try to open a dlg it show a message box saying “A required resource was”.

Any help will be appreciated.

Thank You,
Alfred

This should work.. Handle the PreTranslateMessage() Function in your dialog..

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->message == WM_MBUTTONDOWN)
AfxMessageBox("Middle Button Pressed");

return CDialog::PreTranslateMessage(pMsg);
}
