sir i have to hook the keyboard and get keydown event and which key is pressed and then intercept the wm_char message which is generated for that keydown event and change that particular character and translate that to my own character in extended ascii range.
Sir i have designed a font file and i included lot of new characters in the font file to accomadate more characters which Tamil language have.I can easily manage to access the 52 characeters in A_Z and a-z using normal keyboard , but i have included 200 characters .I am not using unicode for i am not using opentype font but only true type font.the remaining characters are in extended ascii range .Is it possibe to display them by changing the wm_char message.?
If possible then please help me how to intercept that wm_char message which is generated for keydown event and change the defualt character for that keydown event and replace that with my own character.
Thanks in advance

Blush. This may reflect my beginner's ignorance, but what the hell. When scanning various collection classes in the CLR, it seems that there are three basic ways to implement a foreach loop against the collection class:
1. Obvious -- e.g. string from StringCollection
2. Object and casting - e.g. foreach object foo in CollectionClass. In the
loop cast item = (ClassToCast)foo
3. Inheritance -- things like InnerArrayList in CollectionBase
Assuming what I say is true (what are the odds?), then it strikes me that a great article would be to describe hard and fast rules to tell one from the other. Plain and simple, right now, I get a headache looking at CLR collection classes. But, with a good article outlining good ways to discriminate different foreach-able techniques, then I'd really feel empowered.
Am I on to something? Or, is this more Microsoft documentation fog???

I'm running on memory here, but if I recall, the defining factor for making something "foreachable" is implementation of the IEnumerable interface. This is also one of the reason why foreach loops are so damned slow

As Jeremy said, it is all to do with the IEnumerable interface. For more information why not read this really great  article.[^]

I have a fairly simple text template parser. It inserts custom data in place of placeholder tags, and allows custom sub-templates to be inserted based on dynamic conditions.
Anyone interested in this as an article?

ive just gotten my project for third year tetris. dont know where to start what language would be best to work in for a novice ?
|
|

|

What are the requirements? Does it have to be graphical? Does it need to work on multiple platforms? More importantly, what principles do they want you to focus on (data structures, etc.)?

There are many articles on datagrid but i have not yet found a proper, comprehensive one covering all the topics i feel will be generally required while using a datagrid.
Most of the UI in my trial project requires datagrid - but the requirement is in the belowmentioned format:-
1) only single row selection allowed i.e. user cannot select more than 1 row at a given time
2) cell contents non-editable i.e. does not go to edit more on clicking inside a cell
3) Should not display asterisk (append new / addnew) at the bottom of the datagrid
4) only particular columns sortable i.e. i do not want sorting for all the columns
5) customised column header text i.e. i want to display column names different from the default ones from the database
6) alternating colours / formatting for rows
7) set fixed column width which cannot be resized by user
8) Use of panel in the lower half of the page - this panel should display more details about the currently selected record
If there is already such an article(s), please do let me know the url for the same.

if someone has done something like what I need (that is an Access database viewer using DAO) and is kind enough to share the result of his/her work with someone who's just starting out in VC++, I would be extremely grateful. or, if someone could give me some pointers on how to do it, I would appreciate it just as much. thanks'!
hope someone will answer this.
i can't take this anymore! this is way too much pressure!

hi..
i need your help...
i need a project to work on..i have some free time and i wanna make a project...
i am thinking of programming windows using C#..
i want to make a project that will get me an all round tour of windows programming and C#..so that i can code in different areas of windows and c#..
hopefully i want to involve topics such as security,web-based communication,encryption etc.
if you guys can gimme a suggestion for a topic i will be very glad..
i dont really like graphics though..and prefer not working with it..unless its a necessary part of windows programming that is required for some important purpose...\
hope u can gimme some suggestions..
tks a lot
With Regards

Sounds like you need something web-based involving uploads and secure logins or something like that. I suggest you look at some of the articles on this site. You might get some good ideas that way, and you'll certainly find some good tutorials on those subjects.
It's a bit hard to find a project that will cover the full range of areas of Windows programming, BTW. But you might find that you can cover most of them in, say, 3 different projects.

Why is it that C++ cannot utilize a DLL authored in Visual Basic? Is there somebody out there who is mixed language savvy enough to address this issue in an article? I'd be very interested in interfacing between the two or learning how VB / C++ can exchange delimited strings via Winsock / CSocket.
Any ideas?

I do this all the time.
#import "c:\path\to\my\vb.dll" rename_namespace("WHATEVER")
Then simply use
WHATEVER::MyObjectPtr pObj = NULL;
try
{
HRESULT hr = pObj.CreateInstance( __uuidof(WHATEVER::MyObject) );
if (FAILED(hr))
{
_com_issue_error(hr);
}
pObj->DoStuff();
}
catch (_com_error& e)
{
}
You still want an article?

Cool! #import looks like a powerful directive, but how can it allow me to reference the VB DLL's method? Specifically, my VB DLL has one string function, "Execute", which accepts a string as an argument. So I'm not surprised to see the compiler complain that MyObjectPtr is not a member of WHATEVER. But when I replace "MyObjectPtr" with "Execute" I still get the same complaint.
I really appreciate your help Tom. Thanks in advance for any insight you might wish to share.
Haha! Yeah, maybe a short article. You can bet I'm going to create a few notes of my own if I ever get this approach to work.

Short answer...
You can use BSTR, CComBSTR, or _bstr_t datatypes to transmit strings over COM. I like _bstr_t the best because you can easily use any string and cast it to a _bstr_t without worrying about memory allocation. Confused? Don't be. A little bit of reading should clear up your questions.
The long answer...
I will put this in an article. I don't know when I'll get it done. But I'll shoot for this weekend.

I have made better progress, but I seem to be up against a wall with this particular error:
warning C4042: '_IID' : has bad storage class
It doesn't seem to make any difference what type I define in VB to pass/return to/from the DLL. Byte, Integer, String, Variant -- all yield the same error.

hello karl
well the VB's DLL is a ActiveX DLL which supports the COM
so the functions exported by the VB's DLL can be called through the VB program.
But You can call Funtion from DLL of C++ through VB
so do not worry abt calling the VB's DLL through C++
and remove it from your mind

I was wondering if anyone knows of any good tutorials out there on this? I got the exchange 200 SDK, and it is all VS 5 and 6 stuff. In particular, I am trying to discover, how to connect to exchange, and to send and receive messages.
The reason for this, is that I want to build on the webaccess provided with Exchange.
Thanks
