Hi,
I need to show different tooltips for different positions in the same window.How to implement this.
|
|
|
|
|
First of all, check the rect position of tooltips, and make tooltips each and all.
I implemented it once.
There are two men, one is a programmer, another is a man.

I made a printer driver installing program.
Adding printer and adding printer driver work perpectly.
In adding printer, I check that the same printer driver have been already installed with OpenPrinter().
I use a handle from OpenPrinter() to implement DeletePrinter(). I think this is common way.
But DeletePrinter() don't work.
DesiredAccess, member of PRINTER_DEFAULTS that specifies desired access rights for a printerstructure, affect the operation of the SetPrinter and DeletePrinter functions on MSDN.
So I did OpenPrinter() with setting DesiredAccess, but this cause an error, Unhandled exception in Install.exe (WINSPOOL.DRV):0xC0000005:Access violation.
Please advise me after check my source following.
////////////////////////////////////////////////////////////////////////////////////////////
PRINTER_DEFAULTS stPD;
HANDLE hPrt;
stPD.DesiredAccess = PRINTER_ALL_ACCESS;
if ( OpenPrinter( (char*)(LPCTSTR)sName, &hPrt, (LPPRINTER_DEFAULTS)&stPD) )
{
sTmp = "Already, same driver is installed.\nReplace old driver with new driver?";
if (IDYES != MessageBox(sTmp, sCoName, MB_ICONQUESTION|MB_YESNO))
{
MessageBox("Driver install is canceled.");
return;
}
if (!DeletePrinter(hPrt))
{
sTmp.Format("Can't delete driver (Error No. %d)", GetLastError());
MessageBox(sTmp);
return;
}
}

I am wondering if the VC compiler uses multiple threads in compiling source code, i.e. will compilation speed scale linearly with number of processors?

when i create a project following the wizard, I may find
the final installation files include all the files i put
into the file group of this project such as my exe file,
my icon file and so on.
Someone told me I can create a single setup.exe file by
using the tool PackageForTheWeb of installshield, but I
still want to know how can i create a project only include
some installshield stardard files (i.e. data1.cab,
licence.txt, setup.exe and so on) just like some other
softwares. I think all my own program files should be in
the data1.cab, shouldn't it?
Thank you.

Why don't run the same programe code on vc++ compiler,but it is run good on dev-c++ compiler.
The code is
#include "stdafx.h"
#include <windows.h>
LRESULT CALLBACK WindowProcedure(HWND, UINT, WPARAM, LPARAM);

No-one is going to wade through your code if you don't even say what the error is, but VC6 is one of the worst compilers for C++ standards conformance.

LOL - so the compiler works fine then. If it works with your other compiler and runs, chances are it's inserting a workaround for a function you're calling that is NT only. Or your build settings are creating the problem.

I can see that, I'm not stupid.

Well, this code:
if (!RegisterClassEx(&wincl))
{
MessageBox(NULL,TEXT("this program required windows nt!"),
szClassName,MB_ICONERROR);
return 0;
}
seems to be your problem. Now, I presume this means you got the code from somewhere else, if you couldn't work out that this is the source of your dialog, and you blamed the compiler. Either way, your window class is failing to register.

VS.NET 2003, but I've written lots of Win32 code in VC6.

W2000 IS windows NT. Your message box seemed a bit odd to me. OK, in that case, you need to figure out why RegisterWindowEx is failing.

Call GetLastError() when the function fails, and instead of showing a MessageBox saying "This program requires Windows NT" or whatever, show a messagebox with the error code GetLastError() returns. Then post the error code here.

So ?
Where did you get the starting code from ? It's obvious you did not write it. What are you trying to achieve ? I think you need to do some console programming first and learn enough about C++ to understand the difference between compile time and run time errors. That is friendly advice, not an insult.

That's what I was scared of. You *can't* learn programming windows in C++, until you know some C++. You have the Petzold book ? You're doing things the hard way, you should probably use MFC if you're going to use C++.
