Have you declared your function like this?
extern "C" __declspec(dllexport) int WINAPI SumValue(int); If not, you might want to give it a try to see if this fixes your problem.

I use Visual C++ 6.0 Professional with Visual Studio. In the Dialog design
tool I would like to put a raised bump line or a sunken line grove onto
the dialog. The problem is that for reasons unknown to me there is no
LINE tool on the Dialog Controls Palette Tool bar. Can anyone tell me
how to design a line into my dialog at design time? Then also is there
some way to add a line tool to the Dialog Controls Tool Bar?
Thanks
Mike

THis bevel line control should do what you need:

Add a "Picture" control from the resource editor's Controls pallette. Set its "Type" to "Frame" and its "Color" to "Etched". To create a horizontal line, resize the control so that its height is zero; to create a vertical control, set its width to zero.

you couldn't set it to zero. Instead, you can set it to one. I think that is what you want to say.

This is a great idea Ravi. I like this solution because it can be totally handled at design time and requires no code to be added. After all who wants to have to add more code to draw a line on a Dialog Box.....
I still miss the old Borland BC3.1 C C++ compiler from 10 years ago for programming with Win 3.1 & WFW. Their RESOURCE WORKSHOP tool had a nice line control with six separate styles to pick from....Why today does MS not support the lowly line????

I get the following error trying to map a network drive. Obviously it's a conversion issue. How do I convert a CString to the proper type that is needed?
:ERROR C2679:
"binary '=' : no operator defined which takes a right-hand operand of type 'class CString' (or there is no acceptable conversion)"
//Begin Source
CString m_strResource;
NETRESOURCE resource;
resource.dwType = RESOURCETYPE_ANY;
resource.lpRemoteName = m_strResource; // Doesn't work
resource.lpRemoteName = "\\\\Server\\Share"; // Works
resource.lpProvider = NULL;
DWORD result = WNetAddConnection2(&resource, m_strPassword, m_strUsername, 0);
//End Source
|
|

The problem is that resource.lpRemoteName is a LPTSTR, and CString casts only to LPCTSTR (note the additional C for "const"). In this particular case, you know the conversion from LPCTSTR to LPTSTR is safe, as WNetAddConnection2 (hopefully) does not change the NETRESOURCE passed in, so you can force the casting with
resource.lpRemoteName = const_cast<LPTSTR>(LPCTSTR(m_strResource))

Hello,
I assume that by the time we get from :
CString m_strResource;
to :
resource.lpRemoteName = m_strResource;
"m_strResource" would have been set to a valid string value.
Now, from the documentation of the "NETRESOURCE" struct, the field "lpRemoteName" is LPTSTR. Thus, you need to :
1. First cast "m_strResource" to an LPCTSTR.
2. Next cast the resultant "(LPCTSTR)m_strResource" to an LPTSTR.
For example :
resource.lpRemoteName = (LPTSTR)((LPCTSTR)m_strResource);
The casting from a CString to an LPCTSTR will be successful because CString has a "LPCTSTR" casting operator.
The casting from the resultant "(LPCTSTR)m_strResource" to an LPTSTR will be successful because it is a normal casting operation in C/C++ albeit not something to be encouraged.
Please give it a try and let us know how things turn out. Good luck !
Best Regards,
Bio.

Thanks for the help - it's now working with the following statement.
resource.lpRemoteName = const_cast<lptstr>((LPCTSTR)m_strResource);
The program reads a text file line by line contains drive mappings. I then pass the line as a CString to a function. The function then extracts the Drive letter and Resource name from the CString and then passes those values to NETRESOURCE and creates the connections.
It was mention that this type of casting should not be encouraged... what would be the proper way of performing this?

This is the proper way --it is not your fault, but that of the MS guy who defined NETRESOURCE and WNetAddConnection2 witthout caring about constness.

Hello,
I am trying to figure out if it is possible to display 256 colors in a SDI tool bar button.
Any ideas?
Rob

Apparently, regular CToolBars support more than 16 colors. Check Kirk Stowell's article Using Hot Toolbar Buttons, where he discusses this issue (among other things).

It depends on your image list. When you create your CImageList use the ILC_COLOR8 flag for 256 colors. You can even use ILC_COLOR24 for a true color bitmap.

Hello,
I use this bit of code to pull the text(source) from a provided url.. Maybe you can see something different with this code vrs yours.
CString CUserProfileDlg::GetFile(const char *url, const char *filename)
{
char httpbuff[HTTPBUFLEN];
TCHAR szCause[2048];
CString Cause;
Cause.Format("YES");
TRY
{
CInternetSession mysession;
CStdioFile *remotefile = mysession.OpenURL(url,1,INTERNET_FLAG_TRANSFER_BINARY|INTERNET_FLAG_RELOAD);
CFile myfile(filename, CFile::modeCreate|CFile::modeWrite|CFile::typeBinary);
int numbytes;
while (numbytes = remotefile->Read(httpbuff, HTTPBUFLEN))
{
myfile.Write(httpbuff, numbytes);
}
}
CATCH_ALL(error)
{
error->GetErrorMessage(szCause,2046,NULL);
Cause.Format("%s",szCause);
}
END_CATCH_ALL;
return (Cause);
}

Can I use an Active X in a ISAPI ? I have an Active x that I can use in a standard MFC application and I want to use it in an ISAPI (made in C++ with MFC), how can I do that ? I tried to put my Active X in a invisble dialog and then create the dialog and access a function that use the active x, but it only work in my standard MFC application, not in the ISAPI. Please help me, I have a prototype to deliver next week....
Thanks,
Guillaume Frechette

How exactly does the ActiveX fail? Can you create the ActiveX control? If not, what is the HRESULT fail code?
On important factor is that the ISAPI DLL is run in the IIS process, and is run as the IUSR_computername account. Does this account have access to this ActiveX control?

Humm,
maybe I didn't create it correctly, because I only declare the variable of my ActiveX, initialize everything...Normally, the mfc windows create the control itself, so I presume that my invisible windows trick should works Should I do it with CreateControl(); ? Maybe it's my IUSR_MYCOMPUTER that doesn't have the right to use it. I will give it a try...
Thanks

How do I invoke a Common File Open Dialog with MFC's CFileDialog class and have its initial folder view as the root of my shell namespace extension. I have created a shell namespace extension to browse dicuments on a remote computer, when I invoke CFileDialog::DoModal() I can browse to my shell namespace OK and select files OK, but I cannot set the initialDir to the root of my shell namespace.
Many Thanks
