Hello,
Currently I am working on a very simle programme which should work like Windows notepad, suddenly I ve got stuck with saving and opening files.
Especially use of OPENFILENAME is very ununderstandable for me, I ve seen a couple of examples on that but I dont still understand.
What libraries should I include and how should I declare the OPENFILENAME structure so it does work?
Can you please create a little peace of code where is the structure clearly obvious.
Thanks very much for your time
Main references:
GetOpenFileName
OPENFILENAME
The first link has a code example link in the examples section:Code:... OPENFILENAME ofn; // common dialog box structure char szFile[260]; // buffer for file name // Initialize OPENFILENAME ZeroMemory(&ofn, sizeof(ofn)); ofn.lStructSize = sizeof(ofn); ofn.hwndOwner = hwnd; // handle to owner window ofn.lpstrFile = szFile; // // Set lpstrFile[0] to '\0' so that GetOpenFileName does not // use the contents of szFile to initialize itself. // ofn.lpstrTitle = TEXT("Your Title Here"); ofn.lpstrFile[0] = '\0'; ofn.nMaxFile = sizeof(szFile); // filter name followed by null followed by filter extension, // repeat for each filter, and end list with double-null ofn.lpstrFilter = "All\0*.*\0Text\0*.TXT\0"; ofn.nFilterIndex = 1; // initial filter to select ofn.lpstrFileTitle = NULL; // initial file to select ofn.nMaxFileTitle = 0; ofn.lpstrInitialDir = NULL; ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST; // Display the Open dialog box. if(GetOpenFileName(&ofn) == TRUE) // check the return value //now you can do something with lpstrFile
Well that is pretty strange, the code which I tried before was quite similar to yours. Either one didnt work.
The programme appears not to even recognise the OPENFILENAME structure.
If i type :
The compiller return error that "ofn" even OPENFILENAME is not declared.Code:OPENFILENAME ofn;
When I type a (dot) ofter "ofn" no popup combo box filled with possible varialbes appears as it should.
I dont see where is the problem, maybe I have forgotten to include some important library? (<windows.h> is already included...)
Why would you put a period after the init of a struct?
I'm assuming you have your code in a function by itself (...or maybe not), either way, post your code.
Lets stay at the previous examle its mostly the same as I have...
If I type the first line of the code the compiller should not return error that OPENFILENAME is not declared as it returns in my project... Somewhere there is problem with the OPENFILENAME struct but I cant find out where.
If I use whole code as it is posted it returns about 18 errors, madness isnt it.
Have you got any idea why might my compiller does not recognize the OPENFILENAME struct?
See msdn's of OPENFILENAME and go below to see the required headers..But I'm sure as, a programmer, you visit this site first
* PC: Intel Core 2 DUO E6550 @ 2.33 GHz with 2 GB RAM: Archlinux-i686 with xfce4.
* Laptop: Intel Core 2 DUO T6600 @ 2.20 GHz with 4 GB RAM: Archlinux-x86-64 with xfce4.
Unfortunately I did previously, Ive got <windows.h> included I tried to add the commdlg.dll to additional dependencies but either worked.Originally Posted by Joelito

Am I forgetting something else? At this point I have no idea why this problem occurs.
From this, the first things I would try would be to include commdlg.h, and if that didn't work, link with comdlg32.lib.Minimum DLL Version: comdlg32.dll
Header Declared in: Commdlg.h, include Windows.h
Import library: Comdlg32.lib
Minimum operating systems: Windows 95, Windows NT 3.1
Unicode Implemented as: ANSI and Unicode versions.
As for any weird behaviour:You may need to use certain #defines for compatability issues.

I had too. But not just to get the compiler to recognize a struct!
You could put this line before the include of window.h and see if it helps.
Code:#define _WIN32_WINNT 0x0500
What compiler and IDE are you using?

He has both DEV and VISUAL. Not sure which one he's using for this though.
The webmaster really needs to replace the Location info with Compiler/IDE info.
I am using VISUAL STUDIO 2005
What is quite strange that in some precreated project which containes OPENFILENAME there is no problem with it. But if I start using this struct in blank project it fails to work.
because it probably links comdlg32.lib for you, did you try that yet?

That can't be the problem. OPENFILENAME is declared in the header. So linked to comdlg32.lib or not the compiler should see it.
I'm assuming you have this declared somewhere right Gordon?Code:#define _WIN32_WINNT 0x0500 #include <windows.h> #include <commctrl.h>
Yes I have tried including the <windows.h> even linking to comdlg32.lib but either failed
