You also might want to check the attributes for FILE_ATTRIBUTE_DIRECTORY to make sure it is not a file.

_access(), GetFileAttributes(), and CFile::GetStatus() are my favorites.

After clicking on it, the checkbox part then displayed.(Windows 2k Pro., VC6++)

Hello.
I am designing an application that requires the support of SSL/TLS layer socket transfer. I would like to know what is the most extensible solution.
- OpenSSL
- Win32 SSL API
The Win32 SSL API is quicker in terms of implementation. OpenSSL requires the use and in-depth knowledge of how the library handles I/O.
My primary concern is with non-blocking I/O model. Part of the design includes an OVERLAPPED I/O model via winsock. I have no problem blending Win32 SSL API with the current OVERLAPPED I/O. However, OpenSSL is somewhat different. Here is what OpenSSL design could end up.
- Winsock connect
- Associate socket to OpenSSL layer (global context)
- OpenSSL connect
- sent/recv via OpenSSL API
OpenSSL does support an event callback interface. However, is its send and receive API blocking or non-blocking? How will it affect the winsock OVERLAPPED layer? In other words, if there is incoming data, will OpenSSL handles the callback or will winsock handle the callback?
Thanks,
Kuphryn

Anyone know how to accomplish this? I want an effect similar to the one that Trillian uses for its custom buttons.

Hello,
Sorry to bother you all but i am experiencing a little nasty problem and since i am quite a newbie to MFC programming, i really don't know where to go to find a solution by myself.
I have a project of mine, developed under windows xp pro / visual c++ .net 2003. When i compile the program and make a setup for it, everything works fine as long as my application runs under windows xp / windows 2000 / windows NT. If the application is installed under windows ME / 98, the visual c++ runtime complains reporting an enigmatic error:
Runtime Error!
Program C:\......
This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.
For me that means that the runtime provided with visual c++ 2003 is not compatible with the latter systems. Unfortunately this program has to run on both platforms.
Is there a way to instruct visual studio to create an executable in a sort of "compatibility mode" or "retro mode", which will produce an executable that can be run under windows 98? It is even ok to have two separate installers (one for 2000/xp and one for 98/me) as long as the installed program will run.
If there is no way to do that how could i solve the problem?

sorry conticello, but i can't see other way to do that but to compile your project under each plateform you want it to run on...
so, you must compile it under WinME and Win98...
TOXCCT >>> GEII power

|
|
|

It looks quite strange to me the fact that visual c++ doesn't have a way to instruct its compiler to produce code backward compatible with windows 98 but, assumed that, another problem arises...
Which compiler to use to compile the source code under windows 98/me ???
Of course not visual studio .net 2003 because it can't be installed on platforms older than windows 2000.
The easiest answer should be to use visual studio 6.0 but i don't own it and even if i can get a copy around i don't feel i can buy it just to compile a single program once.
Does someone have an idea?

How is asking a question on a public forum considered bothersome? It's not like you forced yourself upon anyone.

Hi,
I would like to be able to drag thumbnails from one list control and then have them appear in a pre defined arrangment in another list control (e.g.). What is the standard way of doing this? Is there a specialised control for this. I just want to be able to drag the thumbnails to another user defined grid . Say 1:1 layout or 4x4 (16) thumbnails.
Regards,

I'm trying to display the PI symbol on certain static text variables in a Dialog box. I know I can set all the text in the dialog box to the symbol font but is there a way using SetFont in the OnInitDialog() function to allow me to change the only certain ones to the symbol PI?
Also how would I put a subscript/superscript on a static text? Would this be done using some sort of RichEdit?
Any help would be nice.

1. Remember to delete your font after use.
2. This is only a sample, please custom it yourself

why delete the font after you used the SetFont()? Please refer to : http://www.flounder.com/detach.htm

Did you know that you could modify your original response instead of creating more?

I have been reading line after line of code and instructions of classes and instances, declarations and structures....I think I get it and I try to write a program but It just doesnt want to come together. I have been reading about C++ on and off for years now and I understand fully what many of the functions and structural components of C++ are and how they work....but something seems to be flying right over my head! I scan thru these forums and hear talk about all different kinds of wacky functions and what not and have NO CLUE whats going on.. Does anybody have any suggestions as to where I might go for help/tips or some incite as to how they went about starting their coding career? Thanks in advance!

The best place to start is at the beginning.
Imho, the most difficult aspect of learning/teaching a subject has to do with mastering the basics. For it is during this phase that interaction between a student and the instructor is usually at its most intense. I suspect you're having difficulty grasping some of the fundamental concepts of programming, and rightly so. You can (relatively) easily teach yourself a new language, but understanding the basics requires a good instructor, a lot of hand waving, and eye contact.
That being said, I suggest you enroll yourself at a local university or community college and get a few computer science courses under your belt. Armed with the knowledge that you may have picked up reading and browsing this forum, you'll probably enjoy taking the courses more than some of your other classmates.
Here's a suggested curriculum. The actual course names may vary, but try to get this material under your belt.- Introduction to programming (logic, flowcharting, boolean algebra, C)
- Data structures
- Object oriented programming (C++, Java)
- Design patterns
Of course, simply understanding this material is not sufficient. You'll need to write hundreds of programs in which you apply your knowledge. That, imho, is the real process of learning.
Good luck and feel free to ask lots of questions!

Go to school. Also don't try to learn c++, maybe just the basics, e.g. syntax and try to get to newer technologies like vc++6 or .net languages... also don't just try to read about c++, try to actually make things with your knowledge because if you don't it will go as fast out of your head as it came in. Right now I'm studying directx and how to make games... if you think c++ functions are hard try directx functions in c++;P.

Hello, there,
I'd like to know how I can display tooltips on CToolBarCtrl when the CToolBarCtrl's window doesn't have focus. I put a CToolBarCtrl in a win32 window. But it won't display the tooltips when the win32 window doesn't have focus. I want the tooltip displayed even when the win32 doesn't have focus. When I move the mouse over the button, I can see the hot tracking, but no tooltips.
I noticed in IE window, the tooltips of links will show up even when the IE window doesn't have focus.
Thanks a lot in advance.

I inserted a ListBox in Form of CFormView and set it to Report type from the property. Using the control variable of the List Box the columns were inserted.
But while inserting Item using
int InsertItem( const LVITEM* pItem ); overload of the function, the call to LVN_GETDISPINFO is not sent and hence the items are not displayed.
the snippets of code
iteminfo *it = new iteminfo;<br />
it->Donum = m_donum;<br />
it->weight = allocate[i]/5;<br />
it->truck = it->weight/10;<br />
<br />
LV_ITEM lvi;<br />
lvi.mask = LVIF_TEXT|LVIF_PARAM;<br />
lvi.iItem = i;<br />
lvi.iSubItem = 0;<br />
lvi.iImage = 0;<br />
lvi.pszText = LPSTR_TEXTCALLBACK;<br />
lvi.lParam = (LPARAM)it;<br />
m_list.InsertItem(&lvi);<br />
i++;
and this being the LVN_GETDISPINFO message handler
void CTruckBillView::OnGetdispinfoList(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
LV_DISPINFO* pDispInfo = (LV_DISPINFO*)pNMHDR;<br />
CString string;<br />
<br />
if(pDispInfo->item.mask & LVIF_TEXT)<br />
{<br />
iteminfo *pitem = (iteminfo *)pDispInfo->item.lParam;<br />
<br />
switch(pDispInfo->item.iSubItem)<br />
{<br />
case 0:<br />
strcpy(pDispInfo->item.pszText,m_donum);<br />
break;<br />
case 1:<br />
string.Format("%.2f",pitem->weight);<br />
strcpy(pDispInfo->item.pszText,(const char*)str);<br />
break;<br />
case 2:<br />
string.Format("%.0f",pitem->truck);<br />
strcpy(pDispInfo->item.pszText,(const char*)str);<br />
break; <br />
}<br />
}<br />
<br />
*pResult = 0;<br />
}
Thanks in advance
