Hi again, Mike,
I've seen I misspelled one (or more???) word(s): 'popupating' should of course be 'populating', but since I'm neither English nor American, so my English is not so perfect 
Also, I've seen that the processed code (after submitting the article) is removing tabs and/or spaces, so the code snippet is sometimes hard to read.
Sorry for that, but that's out of my control...
Regards,
Geert

Recently I was given the job to develop functions for the named subjetcs in the Subject field of this post. Date and time I found came along pretty decently and numeric wasnt too bad except for negative sign quirks. Curency added a few more quirks to the negative sign because it tosses in a dollar sign format too. Basically I am writing this today in hopes that someone may read it and be able to supply me with some better insight on easy ways to create these functions. Little tricks maybe, if they exist, which I'm sure theys do. I am only 3months into my experiences with VC++ but I got a decent grasp on these conversions. In fact the implementation of them is underway but I feel they can be improved. If you care to aid me in this at all please email me. Thank You before the fact ...

hi,
I wanted to know if there was a way to add to IE's context menu, but not through the registry. My menu items change at the time of invoking the context menu and the menu needs to be dynamic.
I have got as far as displaying my menu prior to IE context menu. If the user cancel my menu IE's context menu is displayed.
But I need to put my menu to IE.
Thanks

I have a problem using bookmarks with MS Jet OLEDB provider.
I couldn't find of what data type/size are they, so my calls to their functions always fail. Thanks

I'd like to make my MFC/VC++5 doc-view MDI program work like Microsoft Word: when the user clicks on an inactive view then that click ONLY selects the view rather than selecting the stuff within the view.
The standard MFC behaviour selects the view and ALSO passes the mouse click to the view.
I *think* the solution lies with CView::OnMouseActivate() which is called by the framework during the click. My initial attempt simply used default processing then converted an "activate" return into a "activate-but-ignore-click" return:
afx_msg int CMyView::OnMouseActivate(CWnd* pDesktopWnd, UINT nHitTest, UINT message)
{
int nResult = CView::OnMouseActivate(pDesktopWnd, nHitTest, message);
if (nResult == MA_ACTIVATE)
nResult = MA_ACTIVATEANDEAT;
return nResult;
}
This works great. Too great...
Now ALL mouse clicks get ignored! There's something in the back of my mind about MDI behaviour here.
Am I on the right track ?
Am I missing some step ?
Many thanks
Steve

How would one go about stripping the exports from a DLL? or simply hidding them form say a util like the Dependancy Walker that comes with VC++.
|
|
|
|
|
I think both methods require a def file (not always a given with a VC project, you may need to create and specify one).
The first method simply exports by ordinal and uses the NONNAME keyword to hide the not_as_mangled_as_we_would_like function names:
EXPORTS
; Explicit exports can go here
;MyClass::MyClass(void)"
??0MyClass@@QAE@XZ @1 NONAME
;MyClass::~MyClass(void)"
??1MyClass@@UAE@XZ @2 NONAME
??yadayada...
i.e. once you have a def file, you edit it supplying the @1 NONAME stuff.
Note: for home use you can leave in the related method name in comments as I have.
The DLLs exports will then appear to the dependency viewer as a series of ordinals, and you'll be able to count the exported functions, but informative names like 'CatchFireAndDeleteHitchhikerExe' will be gone.
There is another method that will remove the ordinals as well, [I think], but when we got this far we went for pizza.

Can anyone recommend a tool that will accept two executable images and detail the differences between all of the resources in the two images?
We need to do this for localization.
Here is the problem:
We version control the English version of a module.
We also send all relevant resources out for translation.
Meanwhile, the developer is still modifying the English resources.
We then get the localized resources back, and want to apply the changes made between the two English versions to the localized version, if we only knew what those changes were.
The developers are typically too 'busy' to detail every change they made to the resources in the meantime.
So, a tool that can list every change made between the two modules' resources would be very helpful.
Any URL for websites, names of programs, etc. would be most appreciated.

Why can't you compare the resource scripts?
A few URLs that could help:
Programmer's Tools
Sudden Discharge
I know of a tool - ResourceHacker - that is able to decompile resources.

Hello...
I am rather familiar with MFC, Windows..
Now I found that soon there will be much needs for COM,
I really want to get inside the ATL..
First of all I need a book that leads me the right way..
(With a month of searching for COM, now I can only use them)
What Book Would You Recommand?
I found "ATL Internals", "Inside ATL", "professional ATL..."
And any more?
Above All If there is good way to get familiar with ATL,
Please Recommand it to me...
Regards
-a beginner

Hi,
First of all learn the basics of COM programming itself no matter what are you going to use later VB, MFC, ATL or pure C++. Check "Essential COM" by Don Box, it's a nice book for the beginners. Then when you understand what is COM about you can jump into the ATL.
Regards,
Alex Gorev,

"Essential COM" .... For a beginner, hmmmm.
Sorry Alex but....
yes I learned a lot from the Essential COM book. heck, I always thought that Don invented COM..
***BUT***
In the first 4 times  I have tried to read the book I always get stuck on the fifth chapter... where Don suddenly speaks in different language
I believe Essential COM is a great book. However it is not for beginners (at least not all chapters)
I recommend, an easier path before digging into Essential COM. like "Understanding DCOM " by William Rubin and Marshall Brain.
Then digging into "Essential COM"
"Essential COM" is a great book, read it after you get your self familiar with the basic concepts first. I did.
This is my Story and I am sticking to it

I have been learning C++ and MFC for the past year, and I still feel like I'm struggling! How long did it take anyone else to learn it, and be able to say that they were confident using it? It seems that there is so much to learn.....can anyone recommend a book that really gave them a handle on it??

Personally, I think it took about 6 months of fairly dedicated effort to learn MFC. MFC was really my first foray into serious O-O development (and I've subsequently learned that MFC is not the best place to learn O-O, sigh...)
To me, learning anything requires a project that demands you figure out problems. I've always used a contact manager/mailing list project my goal as I move from language to language, as it covers most of the needed areas (UI, data access, alogritms, etc.)
First and foremost, make sure you understanding how to program Windows itself (which is *not* OO at all), understanding the basics is key to understanding why MFC does what it does. I had a great book on Borland C++ 4.5 that got me that far, but I'd have trouble recommending that today.
Mastering MFC to me is more about understanding it's wide array of idiosyncratic behaviors. You'll know what you want to do, but it will not be obvious how to get there. A book like Eugène Kain's MFC Answer book will be helpful in outlining this.
If you're serious about developing apps with MFC, you should consider buying a library, like the Dundas toolbox, I found the ability to dig through their code and see how they solved things invaluable.

Hey I'm still learning after almost 2 yrs
But I managed to make cash as an independant developer after 4 months! however I had some other relevant experience before that.
I think you need to initially break it down into 4 parts,
1.)The Visual C++ WorkSpace eg VC++6
2.) C or C+
3.) Windows API
4.) MFC,
If you can break your main problem area down into one of the last 3 areas and work on the area that gives you the most difficulty it may help. Don't worry about the other areas, for a while, When you get to know one of those 3 areas really well, I bet the other areas will fall into place quickly.
I find I still fall back on my beginners books for syntax and procedual reference, as much as the intermediate and advanced books, I use now.
Sorry I'm reluctant to name any books as I believe an authors style has as much influence as anything in learning,
So unfortunatly I keep buying "good" books but until I find one that suits me

Hi,
Another very good book is 'Programming Windows 95 with MFC', written by Jeff Prosise. Altough one could get the impression this book is 'outdated' (because of the number '95' in the title ), it isn't outdated at all!
This book does not talk a lot about the Visual Studio environment, but mainly about how to efficienty use MFC. Jeff is starting from the 'good old days' by giving an example of how Windows programs had to be written in the past. Then he gradually changes over to writing Windows programs nowadays with the help of MFC. He does this really nice.
He also gives a lot of pitfalls you have to pay attention to. It's a must if you want to know more about efficient use of MFC.
Perhaps there's already a new issue of the book (with '98' or even '2000' in the title??? ), but if you still can get the 'old' one, don't hesitate to buy it. ISBN number: 1-55615-902-1. The issue I have is from 1996, but still very much up to date for the basic MFC stuff.
Also the book of Eugene Kain, 'The MFC Answer Book', is very instructive and educational, as already mentioned in another reply on your question.
To have a taste of the book, just visit his web site: http://www.mfcfaq.com . You can have some code snippets and other stuff from his book. This is really a 'try before you buy' site, which I very much appreciate.
Hope this info is useful
Best regards,
Geert

Hi,
I've got a 3rd party activex control embedded in a dialog App, occassionally the activex generates an unspecified error resulting in a blank error message box,
Whilst the errors aren't integral to my main application, And if necessary I can work arround them, The Messagebox is a pain, Anyone know how to silence an activex from doing this,
Regardz

Geez, talk about a crappy ActiveX control! It just goes ahead and displays error messages when there's a problem and to top it off, the message is blank! I suggest you call these guys up and tell them to send you an improved version. If they refuse, tell them you'll be happy to disclose to the world what a "wonderful" product they have. That may get them going...
If you don't want to go that route, then I suggest you look at writing yourself a system-wide Hook DLL. Then when you detect the message box is about to come up, you can close it down quietly. That's one not-so-nice way to do it, but it's the only way I know of. I had to do something similar a couple of years ago and I got a great jump start from an article I found in CodeGuru -- I don't know if CodeProject has anything like it yet.
Good luck!

Alvaro, the ActiveX is actually a real popular one, on client machines its the swflash.ocx, I bet you have it and unfortunatly its free so I can't hound the makers.
And actually it's my code that causes the errors, I'm asking it for a variable name that doesn't exist in its structure. Unfortunatly if I don't ask I don't know if it exists. I know this sounds illogical.
But there is no way of enumerating the variable structure it appears.
I'll see what I can do with a hook

I have a 600MHz PIII with 256M Ram running windows NT server . Generally apps go along nicely . But if I do a carrige return or a delete at the top of a 16KB source file it takes 5 seconds to respond , and the processor goes from 2% utilisation to 50% .(memory usage stays constatnt around 75MB) I am pulling what little hair I have out in big chunks . Any ideas ?

Are you running any add-ins customizing the IDE?

If its an MFC based project you could try deleting the
.dsw(workspace ) file. Create a new blank workspace and insert the dsp file into this workspace.
robin

|
|
|

This typically happens because of the .NCB file created by VC++. Close down your project and delete this file (in your project's folder).
Let me know if it helps,
Alvaro

Hi!
I have the following problem:
I want to use paper tray 1 (special paper) to print the
first copy and tray 2 (normal white paper) to print the
second copy. I want to do this whithout making the user to
select trays manually.
I've found a struct DEVMODE that has a member
dmDefaultSource that looked promising, but I am not sure how
to set and use this variable. I am not even sure if this is the correct way to solve my problem.
I hope there is someone that can help me.
