I think non-dialog and dialog based applications have the same problem. Because once the mouse move outside a window, the mouse messages won't be sent to the window unless a mouse button has been pressed down. It is capable even to the window used "SetCapture()". Sorry but it's out of my reach to solve this problem. But you can use the sentence "::SetCursor(::LoadCursor(NULL,NULL));" to make your cursor invisble and use the sentence "::SetCursor(::LoadCursor(NULL,IDC_ARROW));" to restore it. And, you can always use GetCursorPos() function to retrieve the mouse cursor's current position.
Hope it can help you.

Yes, your are right, I noticed that it has nothing to do with dialog/non-dialog based application. It just happened that in one I used the mouse capture while the mouse button was down...
Thanks again for your help

Not sure if this is a question or just a rant....
Anyway, I was working on a WTL dialog-based app (WHotfixCheck actually (shameless plug!)) and I added a button which calls up a CFileDialog. Well, just adding a reference to CFileDialog added about 120K, yes 120K, to the release build. Wassup wit' dat?!?
Changing the release optimization from max speed to min size got it down to about 90K, but still... that don't make no sense. CFileDialog doesn't do that much.

All,
When I deleted my static control in my dialog ,and compiled the project,as the result,the rc file got bigger and bigger--4 megas more. Why ? Who could hlep me ? Thanks in advance .

Hi, I have had the same problem with an Active-X Control from Microsoft.
Caused by what ever, the Microsoft Flexgrid grew by every compilation to the double size.
I gave up finding the reason and just deleted the control in the rc-file. (You have to do that in textmode) After inserting it again it worked for a while.
|
|
|
|
|
Hi, I dont know the reason fully. but i faced the same problem b4. and u can open the rc file as a text file in msdev. And go throught it. U might see repeatetive entries for some control. delete them in the text file itself.
This might help.
All the best

hi, it's me again (i think i should register...)
my prob is not a real prob, but here it is:
i'm using a CFileDialog to open/save files, and that works. the only thing is, i want to set the initial directory. i don't like it that i have always to select drive and directory when i'm working longer on a file for example. so i'm planning to use sort of an .ini file for my program. there i want so store the path of the last opened directory.
with CFileDialog, the initial directory is always the same. i tried it with SetCurrentDirectory, but it didn't work. anyway, is there a function that returns the path of the program i'm currently running? in borland c++ (the dos-based  ) it was the first array in argv (remember: int main(int argc, char *argv[]) ).
well, it's not that important, but i want to create a user-friendly program. it simply s#x to select the same directory hundreds of times within 5 minutes, i'm sure you know what i mean
greets,
McEck

You need to make a change to the OPENFILENAME struct of the CFileDialog before calling DoModal():
CFileDialog dlg ( ... );
TCHAR szInitialDir[MAX_PATH];
dlg.m_ofn.lpstrInitialDir = szInitialDir;

I use this to get my Application path.
::GetCurrentDirectory(1024, m_strAppPath.GetBufferSetLength(1024));
m_strAppPath.ReleaseBuffer();
You have to use this before you do anything else with files, since you then change the path. For example in InitInstance.

MFC -
Ok I have a combobox (m_cFilters) and in it I have Filters like:
All Files (*.*)
Text Files (*.tx) ...etc.
I want to grab the part between the parenthesis and store it in a var after the combo box is changed (DropDown combo, btw). I tried mapping the standard combo messages but after the functions return they do not update the combo box. What is the proper way to get the effect I am looking for? Is there an easier way to grab data like this other than straight from the combo string?
Thanks.

I haven't done much work with combo box controls, but I had a similar situation with a list control where i needed to store extra data besides what is displayed. I think you can use the CComboBoxEx object which use the COMBOEXITEM structure instead of LVITEM. You can store a pointer to a filter string (or a pointer to a structure if you need to store more)
<br />
typedef struct { TCHAR szFilter[256];
} FILTERDATA, *PFILTERDATA;<br />
Then just add the structure when adding your items, for list control:
<br />
PFILTERDATA pData = new FILTERDATA;<br />
strcpy(pData->szFilter, szMyFilter);<br />
<br />
COMBOEXITEM item;<br />
memset(&item, 0, sizeof(item));<br />
item.mask = CBEIF_LPARAm | CBEIF_TEXT;<br />
item.lparam = (LPARAM) pData;<br />
item.iItem = -1;<br />
item.pszText = new TCHAR[sizeof(szMyDisplay)];<br />
item.cchText = sizeof(szMyDisplay);<br />
<br />
nItem = m_cFilters.InsertItem(0, &item);<br />
Then when your user selects something do:
<br />
COMBOEXITEM cbi;<br />
ZeroMemory(&cbi, sizeof(COMBOEXITEM));<br />
cbi.iItem = hitTest.iItem;<br />
cbi.mask = CBEIF_PARAM;<br />
m_cFilters.GetItem(&cbi);<br />
<br />
PFILTERDATA pTemp = cbi.lParam;<br />
<br />
CString strTemp;<br />
strTemp.Format("Filter is %s", pTemp->szFilter);<br />
or maybe there's an easier way
btw don't forget to delete the lparam pointer. probably best to subclass the entire control so you can delete the memory in teh destructor

 Do you think Microsoft is planning to replace MFC?
|
|
|
|
|
Where do you get this idea? MFC is here and will be here as long as we don't think it's gone. The apparent *less than normal* focus on MFC now a days I believe is due to Microsoft's marketing blitz to promote their new baby .NET and hence shouldn't be attributed to a full-scale *replacement* plan. But hey I may be wrong, I don't work for them and so I can't read their minds.

I believe that is what they hope to achieve, in that they want to replace C++ altogether with C#. If it happens or not depends on us as much as them. There are two reasons for people to change from C++ and only develop in C#:
1/ Because M$ gives us a compelling reason to do so ( i.e. a better language )
2/ Everyone blindly follows M$.
I don't care if 1/ occurs, good luck to Microsoft for providing a better option. 2/ scares me, because it seems more than likely to me.

It's interesting to see so many of us think that MS has set out to kill their own libraries (e.g. MFC/ATL) they spent so many years to build. (Call this a suicide attempt or MS marketing conspiracy? go figure).
One alternative view on the subject could lie in the fact that MS had a monumental task to roll out something as big as .NET and so, despite of their desire to promote new stuff in MFC/ATL/WTL/MC++, they couldn't do that in the past (call it *resource limitation*?).
I honestly hope and believe that the latter is the case and MS will come out soon to do the catch up they haven't done since .NET was released.
I recently suggested a poll to CP on a similar tone (with the title: "the future of native C++ development on Windows") and was told by Chris that Microsoft is planning to conduct the same / similar poll on CP soon (similar to what they have done on C#). Hope this will happen *real* soon, so that we can express what we feel on this subject.

It's not really that much of a thinker. Their libraries have served them well, but the updates to MFC in VS7 are minimal AFAIK. No company grows from resting on past success. Having provided libraries to make it easier to develop Windows programs in C++, does that mean that they will continue on that track, when they are rolling out a brand new language that gives them the double advantage of stopping cross platform development AND means they OWN the standard so they can make the language do whatever they choose without people complaining what a poor job they do ?

WTL is not supported by M$ at all. Too bad, because it is cool. I believe there are interesting things in the new ATL ( haven't looked yet ), but I don't see why they would release a new language if they also want to keep pushing and developing the old ones ? Surely it's a case of 'that has done it's job, now we are moving to this'. There sure has been enough hype about C++ being 'too hard' and VB being 'not powerful enough' ( the latter is at least true ), to indicate what they are thinking.

They still need to work on C# - the recent poll had them asking what we want in C#. Again, where do you think their efforts will go ?

Yup. It's not officially yet, but from its popularity I see in the WTL newsgroup, I think officially it will be part of VC++ in near future. I also think in recent days, MS has toned down the rhetoric about WTL significantly compared to what it had in the beginning of its release (remember the saying: "WTL should never be released" by Tony G., MS product manager)

I think MS had to release C# because they were under tremendous pressure to compete with Sun's Java. If they have enough resource, they can still make ATL/MFC successful along with new stuff like C#, .NET.
There sure has been enough hype about C++ being 'too hard' and VB being 'not powerful enough' ( the latter is at least true ), to indicate what they are thinking.
I agree. There is much hype on this power and simplicity things. What most of C++ programmers are led to believe that VB is a RAD language while C++ is not. In fact, C++ can have VB-like RAD features, such as "properties" and "events" and products like Borland's C++ Builder (and our own product RadVC on VC++) have proved that a C++ IDE can be made as simple as a VB like RAD IDE. Oh well, that is another story.

I doubt it will be supported, it's not in Microsoft's interest to divert attention from C#.

The only pressure they were under came as a result of their breaking Sun's copyright. If only Stroustrup could sue M$ for their non conformance in the case of C++, then we'd get MS++, the result of reusing the VC++ code. I believe they will run an each way bet, not drop MFC until they are sure people are using C# instead. As for ATL, you need that to write sheel extensions, etc., so ATL is probably safe for now.

Indeed. I don't have anything to add, but I thought I'd be polite and leave the plug in.

What would you like to see in MFC 7 and it's not there? The library is a mature product IMHO.

>> What would you like to see in MFC 7 and it's not there?
MFC is mature, or dated - depends upon your perspective, I suppose.
I'd like to see a lot more integration between MFC and STL for starters. And at least an alternative to the MESSAGE_MAP macro approach to command routing (the current MFC inplementation was designed essentially to overcome size and speed limitations that existed in PCs and operating systems (win 3.x) back in the early nineties - the compromises and limitations that flow from this are no longer valid). Also better use of C++ interfaces, multiple inheritence support for mixin classes for creating command processing controls, and some use of templates - oh, wait, that's probably WTL (maybe I want WTL and MFC to merge ...). And a useful tab control like Delphi/C++ Bulder would make life a lot easier every now and then.
And while I'm at it, I'd also ask for much better code wizard support when using MFC. And how about cleaning up the entire SDI/MDI and Document/View frameworks by allowing easier variations (single document, multiple windows, etc) and Model/View/Controller style interfaces? Does anyone actually create MDI apps anymore ??
And finally, perhaps MS can solve this whole Israel/Palestine/Muslim/Terrorist/USA thing so I can concentrate a little more on how to improve MFC.
>> Not a thing. I'd rather see Microsoft work on ANSI conformance.
Yes, yes, yes. At least get template support up to standard. Please. Pretty Please.
Oh, and Christian - I keep meaning to ask (and I'm too lazy to look it up) - how do I put quotes in italics in a post ??

You're right - it won't be the same as good old MFC. And then we'd need a new name for this new thing. Something very current sounding like, say, ".NET"
And that's why I think MFC is doomed to a long, slow ride into the sunset - it's already dated, and MS has no plans to even try to move it forward. It has no direct support for new C++ concepts/technologies like STL and templates, and little or no direct support for non-C++ things like XML and SOAP. If it doesn't at least try to move/change/evolve then it becomes obsolete, and MFC is well on the way to the destination.
If you want any more proof that MFC is a fading star just look at CodeProject - it exists largely to allow people to extend (ie, overcome the limitations) of MFC in almost every area, and as a clearing house of knowledge of how to deal with MFC's problems.
And some italic text. Hey , whadda know, it works - Thanks Christian

I think you're looking at MFC from the wrong angle. Why the hell should MFC know about SOAP or XML? Use it for what it was created: for encapsulating most often used Win32 stuff, like windowing. I'm using MFC only for rich user interfaces. Personally, I wouldn't be happy if MFC 8 suddenly supported SOAP or had its own XML parser.
We don't live in the world in which there's only one all-encompassing library.
