In the BROWSEINFO structure, set the lpfn member to a callback function. In that callback, send a BFFM_SETSELECTION message back to the SHBrowseForFolder dialog, passing the path in the LPARAM parameter.
See http://www.codeproject.com/editctrl/fileeditctrl.asp[^] for an example of code that does this.

Hi. im kinda used to the "I write the methods and classes, call them from the main()" way of programming but now in MFC I cant find a way of doing this. Does mfc still work that way???
|
|
|
|

It's not just MFC, it's Windows that doesn't work that way.
Windows is an event-driven operating system and needs a completely different approach to programming. Learn what that involves first and then decide whether or not to use MFC to do it.

What you describe is the difference between synchronous and asynchronous programs. DOS and text-based programs are based on the former, while Windows is based on the latter.

From a layman's prepective MFC and Windows apps have InitInstance() and WinMain() as a parallel to "main() programmers"

What in the world are you talking about? Not all MFC applications have an InitInstance() method. While a GUI-based Windows application has a WinMain() function, a text-based Windows application has a main() function.

Do not get the desktop window DC. It causes serious problems.
Instead of this
HWND hDesktopWnd=::GetDesktopWindow();
HDC hDesktopDC=::GetDC(hDesktopWnd); write this
HDC hDesktopDC = ::CreateDC("DISPLAY",0,0,0);

Hi All,
I'm facing a strange problem.
The condition is like this:
minimize the application from the taskbar when a dialog is displayed
or a automatic dialog is displayed when the application is in the minimized position.
When the user clicks to activate this minimized window,only dialog box is coming up and the application's main window still remains minimized.
This is happening sometimes.
Can some one tell me how to make the main window also to come up along with the dialog box when the window is activated from a minimized position
Thanks in advance

Hi,
I am using ReportEvent() to write an event to the event log. I see the event in the event viewer, but then I try to double click it (for properties), event viewer crashes.
I tried reducing the number of characters in the logged event and it works. Does anyone know what the max chars permitted by the event viewer are?
Thanks!

I am trying to debug my app in MS Visual C++ 6.0 and when I come to an unhandled expression I get a dialog that pops up that says: Please enter the path to STRLEN.ASM...all I need to know is which statement is causing the error. Any suggestions?

What line of code is blowing up when you get this ? Or aren't you stepping through your code ?

That's the problem...the dialog pops up and then when I hit cancel it takes me to the funny looking assembly code (or whatever it may be)
|
|
|
|
|
So, you should set a breakpoint and step through the offending code. Or check the stack trace to see where the call has come from.

I'm running embedded visual C++, and creating a little program for pocket pc 2002-3. I have created a menu resource which I want to link to the main dialog that I use. Now for somereason everything compiles correctly, but when I run the program, no menu. hmmmm Anyone out there able to help.

Rebuild all the resources and if it does not work still check the association of the MENU ID with the function that creates it .

i'm making a setup for a c/s program which access oracle database ,use installshield ,can it do without setup oracle at client?Thanks a lot !
|
|
|
|

Your client will need a driver to connect to the Oracle database, but you don't need to install the DB locally, if you're not connecting to it locally.
Oracle sucks, BTW.

How to realize it ?can you tell me more ?Can I use installshield do it ?thanks a lot !!!
|
|
|
|

Your client needs to run the Oracle driver on their machine. I'm sure you can tell installshield to run an external task, but I don't know how.
