i think you know what dll do,i can explain what the function of these three.

here,You create the dll with MFC dll staticlaly link to code.
Pros->You don't need to ship MFC dll with you dll as all required code is compiled with it.
cons -> can made dll bulky and take more memory usage.

same way just viceversa of above.
zahid_ash wrote:

here the most powerfull dll for vc++ appliction we can only export function form above two dll,but you can export classes using this DLL.
only disadvantage of this dll is that it export classes only to VC++ application whereas above two can export function other porgramming lanaguge
i hope you understand the concept

Two solutions:
1) Keep the file nmae in the ini file and save the actual text seperate file
2) Use WritePrivateProfileStruct/GetPrivateProfileStruct.
3) is what you suggested above

Im not sure how to do WritePrivateProfileStruct
so here the code section.
not sure if i should add loop or not.
think the program will ended up in a loop
void CMyDigClockDlg::OnSavenote()
{
char sIniFile[MAX_PATH];
GetModuleFileName( NULL, sIniFile, MAX_PATH );
strcpy( strrchr( sIniFile, '\\' ) + 1, "reminderclock.ini" );
char notepad[MAX_PATH];
int loop;
CString temp_key;
assert(m_notepad);
///WritePrivateProfileString ("NOTEPAD", "note", m_notepad, sIniFile);
for (loop = 0; loop < m_notepad.Get; ++loop)
{
temp_key.Format ("note%2.2d", loop);
WritePrivateProfileStruct ("NOTEPAD", temp_key, (void *)&m_notepad, sizeof(notes), sIniFile);
}
}

I am developing an MDI application in VC++. I need to create an MDI child menu attached to the Child Window without replacing the mainframe's menu. To be more specific my MDI Child window is using CFormView. I should be able to access both the child window menu and the main frame menu both simultaneously at a time. Can you please suggest any solution this.Please email to me if you have any useful relevant information on the above.

It's me again.
I'm still fighting with tabs.
I have 7 tabs with spins on them, and one Dialog.
I use Propertypage, and use the instruction "AddPage" to make the 7 tabs on the dialog.
Now I want to store the spin value in a flie when the user click and change the spin value.
(or maybe in 7 different file, for one tab own one file belong to itself)
Then, I have to communicate with a controller throu RS-232 under modbus portocol.
Because I'm slave on modbus, I only can send data out when the controller send out query message. So I planning to store the spin value in files, then waiting untill the query message, then I send the data I stored in the file.
I would like to ask how to deal with the file pointer.
I use the code:
in my base dialog' cpp:
<br />
FILE *filedlg;<br />
filelog = fopen( "file_page1.txt", "r+" )<br />
What code about pointer assignment I suppose to write in tab page1' cpp or h file to complete the rest? I mean page1 doesn't know the exitance of file pointer filedlg.
I'm new about pointer and MFC, and would be many appriciate about your help.

Dear fellow Programmers,
I am currently facing a situation which I can not figure out how to do it.
I have a property sheet with 5 property pages. When the user press the IDOK button, I want to ensure that all Property pages has been visited by the user, all data on those pages has been entered properly and validated.
How can I do that? So far, I override the OnOK in each page, that function is only processing that particular page and exit directly.
Does anybody has any clue on how to solve this problem ? Please inform me and thank you beforehand.

Why not set it up as a Wizard instead of tab pages with a Next and Prev button. Enable Next when data validation determines everything has been done on the page and when the user gets to the end have a Finish button.
This is IMHO a better way to go if the user must visit all of the pages.
If you want to do it as tabs have a pointer to the property sheet in all the tabs and have a validation routine in the sheet itself. Each routine could then call
if (sheet->IsOK())
EnableWindow(IDOK);
and after each sheet is fully validated call
sheet->Valid(page_x);
Just some quick thoughts.

Thanks Dave,
I think I will try to change to the Wizard Mode and let the users look into it.
If they are not satisfied with it, I will change to the second alternative that you suggested.
Again, thanks for your fruitful information.
Alvin.

Your welcome.
If the users have to touch on all of the pages the wizard will be much easier for them. There is nothing like flailing around trying to figure out why the damned OK button won't enable!
Something to keep in mind. Will the wizard process be repeated often? Will it be basically the same values each time? If it is you either want to save the last values and restore them into the wizard each time it runs or allow the user to store them to a file that can be reloaded from the first or second page to refill all the values. This way the user can just hit Next,Next,Next to quickly repeat. I do this in one of my products where all of the files in each project usually have one format but each project will have unique settings for the files. It works quite well.
Good luck.
Dave

Hello CPians,
Anyone here ever tried loading a font from a font file(*.ttf)?
I need to theme my gui by using a user-created font. But I'm afraid once I send the app out, the user's pc will replace the font with the default font. 
Thank you very much in advance.

What about installing the font as part of the application installation?

"What about installing the font as part of the application installation?"
There's an idea.
But I just started using Visual C++ three months ago.
There are some things I still need to learn, like using the installshield.
I think i need to use installshield to do what you said.
Thanks a heap.

if you really want to do it that way, you'll need to use CreateScalableFontResource and AddFontResource. i'd just install the font as part of the app install - much easier.

Thanks very much.
I'll try to use these functions. Meanwhile, I am studying how to install a font, as generally suggested.

How do I access an URL from within the VB or VC++ code.
my requirement is, I need to create a DLL which accesses an URL, and parses the XML returned(the url I'm accessing returns XML, not HTML).How can I do that in VC++/VB?
Also, are there any classes in VC++/VB for parsing XML returned.
Any sample code would be appreciated.
Everything needs to be non .NET.

there are a whole bunch of xml classes here on cp that u can plug into your code and leverage to do what u want ... have a look in the relevant sections

One of the easiest ways to access web resources is using the MFC WinInet wrapper classes. Take a look at CInternetConnection and related classes. If that does not appeal to you can use the WinInet API directly or even the Winsock2 API to retrieve the web resource.
XML parsers are abundant. To see a large if not complete list of them go to xml.com. Perhaps the most prevalently used parser in Win32 from C++ is the Microsoft MSXML ActiveX control. I have been using it for around 4 years in C++ development. If you are familiar with ATL and _com_ptr_t class using MSXML with the #import directive is a snap.

I have a peculiar question to ask you gurus...
Being the person I am who pays attention to minor details, I was wondering if you could explain me in as much detail as you can why is it that MFC and some Win32 interface methods instead of using the standard C++ bool data-type, use BOOL (which maps to the plain old int) ?
Any insights you could provide would be much apreciated.
Thank you so much,
David Nimrod

BOOL is a type defined by the Windows headers. Since MFC and Win32 were around before bool existed in C++, they use BOOL. (Actually Win32 uses BOOL to maintain C compatibility.)
