Another Question (Dialog Box)

gobby

Satchmo was already very good to answer my last question.
(here -> http://boards.ie/vbulletin/showthread.php?s=&threadid=163299)

Also, I mentioned that I would have more. So here we go!

I have been implementing the search facility by presenting the use with a list of drives and an option to enter a path. My boss thinks that it would be much better if you could click on a button and have a dialog box appear similar to the search box from windows where you can be very accurate about where to search. (I also think it would be better)

Problem is there does not seem to be a standard MFC class for such a dialog box or am i wrong??????????

The only thing I can see that is remotely close is the CFindReplaceDialog which seems to be for searching for text within a document.

Is there a standard dialog for this or will I have to create one?

Any help would be appreciated!

I think I will take that as a 'Yes, you must make your own you lazy git' then :dunno:

Relax mate Try google - if you can't find your answer there then check back here again. Not every one is a C++ head *waves Java rulezzz 4eva flag*

Heh... Yeah, I guess your right on that one. Well, I'm off home so will see what I can dig up tomorrow.

Sorry, haven't done any MFC so can't help you here! However I'm sure the answer you're looking for is buried somewhere in the MSDN Library, all you have to do is find it!

No worries. I will have a look around and possibly somebody in my workplace can help out. Thanks anyways!

All your dialog classes:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_mfc_Dialog_Box_Classes.asp

Depending on what way you go about this there is more than one way to skin a cat as it were...

As I have no idea what youre doing you will know which of these suits best.

I have looked here and in my local MSDN help library. Neither seem to have what I am after. This is bad! I am extremly close to finishing the application and as such I really want to finish it so I can move on.

Mr.StRiPe

sorry you got me on a busy day so didn't have time to create simple example! but the following code does what you want. At least you should have something to lookup in msnd anyway

//Have this as a global variable
HWND g_hMDIClient = NULL;

//hInst is (HINSTANCE hInst) from winmain()
SetUpMDIChildWindowClass(hInst);

	CLIENTCREATESTRUCT ccs;
                //main is the HWND of the main window initialised from winmain()
	ccs.hWindowMenu  = GetSubMenu(GetMenu(main), 2); 
	ccs.idFirstChild = ID_MDI_FIRSTCHILD;

	

g_hMDIClient = CreateWindowEx(WS_EX_CLIENTEDGE, "mdiclient", NULL,
									WS_CHILD | WS_CLIPCHILDREN | WS_VSCROLL | WS_HSCROLL | WS_VISIBLE,CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,main, (HMENU)IDC_MAIN_MDI, GetModuleHandle(NULL), (LPVOID)&ccs);

	if(g_hMDIClient == NULL)
		MessageBox(main, "Could not create MDI client.", "Error", MB_OK | MB_ICONERROR);


// Call this when you want to open dialog box outside of winmain

HWND hChild = CreateNewMDIChild(g_hMDIClient);
	if(hChild)
	{
								DoFileOpen(hChild);	
	}


void DoFileOpen(HWND hwnd)
{
	OPENFILENAME ofn;
	char szFileName[MAX_PATH] = "";

	ZeroMemory(&ofn, sizeof(ofn));

	ofn.lStructSize = sizeof(ofn);
	ofn.hwndOwner = hwnd;
	ofn.lpstrFilter = "Neural Network Files (*.net)\0*.net\0All Files (*.*)\0*.*\0";
	ofn.lpstrFile = szFileName;
	ofn.nMaxFile = MAX_PATH;
	ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
	ofn.lpstrDefExt = "txt";

	if(GetOpenFileName(&ofn))
	{
                 //Put whatever function you want here thats takes the filepath as a string
		OpenNeuralNetwork(szFileName);
	}
}

Wow, cheers Mr.StRiPe. I am heading home now but I think that tomorrow I will have a lot to try. I had also found some examples on MSDN but they were not as good as that.

Hmmm.....

Okay. So I have looked at this code and also at some more code from MSDN help files. I am still very unsure of how this should work. Perhaps I can be a little more specific about what it is that I am trying to do.

What I want is a 'Browse for Folder' dialog box similar to when adding a folder of mp3's to Winamp, for example.

There seems to be some pre constructed dialog boxes such as for opening/saving a file or printing a document but nothing like what I am searching for.

The way I have my 'Search' dialog implemented at the moment is that the user is presented with a list of drives and the option of selecting a drive and also entering a path.

One problem is that in my company people will quite often need to search network locations and as it is, my application does not support this.

What would be ideal is a dialog box that is similar to the windows search facility. Specifically when you select 'Browse' in the 'Look in:' drop box.

I should mention that I am a student and my C++ skills may not be quite as good as I would like. Hence, trying to make sense of someone elses code can take me some time.

My boss is aware of what I am trying to achieve and is currently in contact with some collegues in Stuttgart so hopefully they might have some classes/resources already written but in the meantime I would like to get a better idea of what must be done to achieve what I want to do....

(Public holliday in Germany on Monday so it might be Tuesday before I am able to reply to any posts here. )

Again, thanks for all the replys and I am sorry for being rubbish with Visual C++

[edit] I have about a week to finish this and a couple of other issues...

How about the folder browser at

I'm only going by the screenshots though.

Actually man, thats brilliant! It has really pointed me in the right direction. I would never have found 'SHBrowseForFolder' otherwise!

Cheers to everyone for the help!
