Hii Sandip,
Ya when returning value from dll it is in -VE so it is giving error.
I am not getting what is wrong with my program. please tell me.
My code is like this:

typedef BOOL (WINAPI* ptr_func1)(BSTR* bstr,BSTR* bstr1,BSTR* bstr2,BSTR* bstr3,BSTR* bstr4);
ptr_func1 ProcessingInformation = NULL;
HINSTANCE hLib;

hLib = LoadLibrary(_T("C:\\Program Files\\Microsoft Visual Studio\\My Projects\\BoolDate\\SampleDll.dll"));

if (hLib == NULL)
{
MessageBox(_T("Unable to load .dll"), NULL, MB_ICONERROR);
}
else
{
ProcessingInformation = (ptr_func1)GetProcAddress(hLib,
_T("ProcessingInformation"));

CString str;
BSTR server,usr,pwd,Temp,Temp3;
BOOL bstr;
Temp=SysAllocString(L"21\8\2008");
str=Temp;
MessageBox(str);
Temp3=SysAllocString(L"21\7\2008");
str=Temp3;
MessageBox(str);
server=SysAllocString(L"savitri");
str=server;
MessageBox(str);
usr=SysAllocString(L"root");
str=usr;
MessageBox(str);
pwd=SysAllocString(L"base");
str=pwd;
MessageBox(str);
//bstr=TRUE;
/*bstr=m_UserControl1.Processattendacne(&Temp,&Temp3,&server,&usr,&pwd);
str.Format("%d",bstr);
MessageBox(str);*/
m_Edit1="savitri";
m_Edit2="Base";
MessageBox("Gettting Value");
/* The actual call to the function contained in the dll */
bstr = ProcessingInformation(&Temp,&Temp3,&server,&usr,&pwd);
MessageBox("Gettting BSTR Value");
str.Format("%d",bstr);
MessageBox(str);

SysFreeString(Temp);
SysFreeString(Temp3);
SysFreeString(server);
SysFreeString(usr);
SysFreeString(pwd);
/* Release the Dll */
FreeLibrary(hLib);

please help me out.

Thanks in advance,

Did you check my post above Import[^]

I think you cant use LoadLibrary().
I have given sample code in post above.

Right click a project and select "Set as startup project".

Use ShellExecute or CreateProcess

Somethings seem HARD to do, until we know how to do them.

I think you are posting similar questions again and again.

Question:
Running another executable within GUI of some other executable.

I guess you have got answers that this cant be done in previous post.

Adding multiple projects in one solution is just for convenience, Still they will be different application even though they are in same solution.

If you want the second application as part of your first application. Merge the second application source with first application. Again Adding projects to same solution is not merging. You have to add source files of second application to first.

Is it clear or still you have any doubts??

Hi All,

I have a legacy application that needs to run as both standard user and administrator.
But standard user will have limited priveleges.

So i have added a manifest file with
<requestedExecutionLevel level="asInvoker" uiAccess="false"/>
(I cannot use "requireAdministrator" as the standard user needs to run the without the need to enter administrator credentials>)

But the problem i am facing here is ,even if the logged on user is administrator, he is also behaving like standard user.

Is there any way to get the Logged on administrator token and pass it as first parameter in CheckTokenMembership() API ?

Thanks

I am being paid almost twice the .NET guys with similar experience (my peers) are earning. I am a "VC++ guy". Hope that answers your question.

Since you're certainly far more skilled than "the .NET guys with similar experience", you're obviously cheating. Poke tongue | ;-P

Your reasoning skills are questionable. Just because you've updated your resume and you have 3 years experieicne, that is hardly an indicator that the "VC++ market is down."

That's like posting a question here at 2:00 in the morning and wondering why it has received no responses after 5-6 hours. Most responses from such posters go like, "I guess no one here knows the answer to my question."
