It ONLY works only Windows 98 and I was surprised to learn this as you are!
If you set _UNICODE, and compile it under UNICODE, as a SEPARATE exe or DLL then it works ONLY on Windows 98.
So far, nobody has created a class or piece of code that will compile and create a SINGLE exe or DLL that works on BOTH Windows 98 and Windows 2000.

I'm confused,
Shog9's app work on my Win 2000 and 98 for me.
Have you mangled your 2000 ?

I have looked at every sample of source code i could find on creating Links on the Desktop and EVERY piece of sample code FAILS to create links on Windows 2000--except for those samples that include a separate UNICODE version of the code.
Now it is VERY inconvenient to have to include 2 versions of a program, one in ASCII and another in UNICODE. So what's the answer?
I will offer 2 solutions to this problem that I originally proposed in the "Lounge" where I was told was the wrong place to post anything important or serious!
The first solution is to create 2 versions of your code, and include BOTH versions as a resource in your application and launch the correction version from your program based on the Windows Platform. This works but is not elegant at all--it is the solution that i believe is used by BOTH InstallShield and WYSE Installers! No wonder their exe files are so big!
The other solution I offer below. I believe it will work if compiled on Windows 2000. And it would be nice if someone with Windows 2000 could let me know if it works?
I develop on Windows 98 using Visual Studio 6...
#include "direct.h" /* This is needed for _mkdir */
#include "objbase.h"
#include "shlguid.h"
#include "wchar.h"
#define INITGUID
#include "initguid.h"
//#define INC_OLE2
//#pragma comment( lib , "OLE2")
//#include "ole2.h"
//#include "comcat.h"
//#include "olectl.h"
Where UINT uLinkLoc = CSIDL_DESKTOP;
Is there a way to write a SINGLE class that can create a link on the Desktop in both Windows 98 and Windows 2000 without compiling 2 separate versions(one UNICODE and one ASCII)???

I forgot to include one of the functions that I call in the code sample above and I am including it below.
bool CInstall::GetShellFolderPath(LPCSTR lpShellFolder, LPSTR lpShellPath)
{
//lpShellFolder can be one of the following
//AppData, Cache, Cookies, Desktop, Favorites, Fonts, History, NetHood,
//Personal, Printhood, Programs, Recent, SendTo, Start Menu, Startup,
//Templates, ShellNew
DWORD rc;
DWORD length = MAX_PATH;
DWORD type = REG_SZ;
HKEY hkey;
rc = RegOpenKeyEx(HKEY_CURRENT_USER,
"Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Shell Folders",
0,
KEY_READ,
&hkey);
if (rc == ERROR_SUCCESS)
{
rc = RegQueryValueEx(hkey,
lpShellFolder,
NULL,
&type,
(BYTE *) lpShellPath,
&length);
RegCloseKey(hkey);
}
if (rc == ERROR_SUCCESS)
return true;
else
return false;
}

Have not tested, but if you say a UNICODE build will work
it is maybe because there are 2 IShellLink interfaces, one
IShellLinkA and one IShellLinkW, and if that happens to be
the case you could build an ANSI app and use IShellLinkW and get
it to work
|
|
|
|
|
So if this is the case, then:
if (b2000 || bNT) {
// Call "IShellLinkW"
}
else {
// Call "IShellLinkA"
}
Is this what you had in mind to build 2 versions in one class?
What I don't understand is why hasn't anyone posted a sample of this code before?
Bill SerGio, The Infomercial King

I was thinking, just query for IShellLinkW, if you get it, use it.
Otherwise use IShellLinkA.

Anyone know ehre to get some ASPI documentation?
Thanks in advance.

I was just wondering if there was a way to turn on and off the keyboard lights for CapsLock, NumLock and ScrollLock programmatically.
any help appreciated

How can I get the style of a window class.
Ex: I have a window (handle=0x00000b94, class name=#32770(dialog) )
I want to get the styles and extended styles of it as CS_DBLCLKS, WS_EX_CLIENTEDGE....
How can I do that ?
I try this way:
LONG lStyles=::GetWindowLong(hwnd,GWL_STYLE);
LONG lExStyles=::GetWindowLong(hwnd,GWL_EXSTYLE);
CString strStyles;
if ((lStyles&BS_OWNERDRAW)==BS_OWNERDRAW)
strStyles+="BS_OWNERDRAW";
if ((lStyles&CS_VREDDRAW)==CS_VREDDRAW)
strStyles+="CS_VREDDRAW";
...
...

First off the CS_DBLCLKS is a CLASS style, not a window style
the GetWindowLong, using the GWL_STYLE or GWL_EXSTYLE will only return you the window styles (i.e. WS_XXX ,or WS_EX_XXX)
for CS_XXX you need to call GetClassLong( hwnd, GCL_STYLE )
As far as conmverting them to a string, I think you are stuck with a big if/else statement, sorry !

Dear All,
how can i solve the problem of including the View class header file in the MainFrame.cpp file. when do so an error occure about the GetDocument(); declaration in the view header file.the error says "error C2143: syntax error : missing ';' before '*'"
thanks,
Mohammad Zakarni

You need to include the document class as well. The error is because GetDocument returns a pointer to a document object, so you need to include it first, so it knows what that is.

I got the same error C2143 when I moved a snippet of working code to open a file and load a list box. I put the code in a new file as a good programming practice and I think the error was related to the include header:
#include <fstream>
using namespace std;
Any suggestions?

1. Check 'display this message as is' or use < and > to do < >
2. NEVER use all of namespace std.
3. I really don't know, because I don't know what you included. The problem will be different now, because it's obviously std library stuff you're using. Could you post the offending code and the name of the header ?

When i edit my menu in the resource editor it is OK, but when i start the app, it is
disabled, and i cannot enable it, i tried with handling WM_INITMENU, and enabling the
items there but no success. Only E&xit it OK, it is the only menu item that works,
why is that ?
And another question... Is there any significance which class will contain the menu's
ON_COMMAND handlers ?
|
|
|
|
|
if you are using MFC the menu handler will need to be in a class that has an instance available ..... if you have the menu handler in a doc class that has no open document...then MFC will disable the menu item for you...since there is no handler available to service the request.....if that is not the case, give a little more detailed info.....about the problem

I am Korean and weak English.
I want fax brodcasting service. But I don't know how to use below three API.
I want to know how to working together three below API.
FaxSendDocumentForBroadcast()
FaxCompleteJobParams()
FAX_RECIPIENT_CALLBACK()
Please help me. I searched MSDN and web site.
But there no detail data about FaxSendDocumentForBroadcast().
I attach my fax broadcast project source code.
Thank you very much.
BOOL CALLBACK CALLBACK FAX_RECIPIENT_CALLBACK(
HANDLE FaxHandle, //handle to the fax server
DWORD RecipientNumber, //index indicating current fax recipient
LPVOID Context, //pointer to context information
PFAX_JOB_PARAM pfxParam, // [in,out] pointer to job information structure
PFAX_COVERPAGE_INFO pcpInfo ) // [in,out] pointer to local cover page structure
{
pfxParam->SizeOfStruct = sizeof(FAX_JOB_PARAM);
pfxParam->RecipientNumber = pszFaxNumber; // recipient's fax numbe
pfxParam->ScheduleAction = JSA_NOW; //schedule the transmission at any time in the next 24 hours
if(RecipientNumber > 10) return FALSE;
else return TRUE;
}
void CFaxClientDlg::SendFax()
{
if(!FaxConnectFaxServer(NULL, &fxHandle))
{
DWORD dwError = ::GetLastError();
switch(dwError){
case ERROR_INVALID_PARAMETER:
break;
case ERROR_NOT_ENOUGH_MEMORY:
break;
}
ReportOSError();
FaxClose(fxHandle);
return;
}
/*
if(!FaxCompleteJobParams( &pfxParam, &pcpInfo ) )
{
ReportOSError();
FaxClose(fxHandle);
return;
}
*/
if( FaxSendDocumentForBroadcast(fxHandle, pszFileName, &dwJobId, FAX_RECIPIENT_CALLBACK, NULL) ) /* [out] dwJobId */
AfxMessageBox("SendDoc Succeeded");
else ReportOSError();
// Cleanup here
FaxFreeBuffer(pfxParam);
if ( pcpInfo )
FaxFreeBuffer(pcpInfo);
FaxClose(fxHandle);
}

you didn't find indo on MSDN on this because, (I believe), this is not part of the OS API, Windows has traditionally never provided fax support....this is probably a 3rd party lib, you need to consult the vendor documentation....if Windows is now supporting Fax thru API then it is a new one on me, wouldn't be the first time though!!!!

Windows is now supporting Fax Service and Fax Client API.
From Windows 2000, Windows support FAX SERVICE and I just want to program
fax client.
Below three API is FAX CLIENT API. But I nerver know how working together three API.
