It explains the differences and suggests when you should use what.

I want to knnow how you can use CDC::LineTo in conjunction with Alpha Blending.
My first approach was to do the LineTo into a temporary CDC and then use alpha blending
to copy it to the intended CDC, but when I do so I also copy the black background of my CDC.
I'm stuck!

Look at the WDJ site, I have an article with code for download there regarding alpha blending. Your other option is GDI+, again my articles here cover that side of things. To alpha blend your line, you'd be better off doing your own code to calculate the line and doing the blend directly. Otherwise you're bound to blend on bits you didn't draw to, and you know the value to blend already ( the colour of the line ).

I havent tried this out :-
But it might work
Try calling GetSockName on a connected CSocket

I have to edit controls on a dialog.
They are going to handle hours (the first edit control) and minutes (next edit control).
My question is that I want to catch EVERYTHING that is done in that edit box!
eg:
If I write 24 and max value is 24 a message box will appear and tell the user that 23 is maximum value for that edit box, and I want it to appear while the user is trying to type isn some text in the edit box. Exactly with other too!
HEELP!!

Well, EN_CHANGE is definitely the way to go. Several months ago I posted a message about a request similar to yours: check it out. It contains some code for an CEdit-derived control that performs in-place checking of the user input. Easy task to adapt it to your needs.

OnChange for the control allows you to check per key.
It means though that you have to grab the text of the box, check it, then indicate the error to the user.
For a box that with a maximum of two characters its fast enough, though it can be equally argued that for a box with two characters checking OnExit or when the return key is pressed is just the same.
If your text could be long the OnChange check may be most desirable since the user may need to know before going too far ahead.
In this case the first possible method is wastefull, that is, collecting all text and checking it all every time
H
He
Hel
Hell
Hello
Hello W
etc
For a 256 character line, there is a lot of waste.
So, it is better to remember where you have already checked and where the cursor currently is. If you look at CEdit you will find possitional data available to you which you can use for this within the ::OnChange()
We do it for the joy of seeing the users struggle.

with NetWkstaGetInfo using WKSTA_INFO_100 you can find in this struct the domain name

I just heard there's a limitation under Windows 98 about the number of
ComboBox that an application can create. I can't believe it! 
Did anyone of you heard about this. I searched the MS Knowledge Base but
I didn't find anything yet.

I don't know of any special limitation about comboxes, but it is a well known fact that Win9x systems can only hold 16,364 windows at a time (this includes not only top-level but child windows as well), which is admittedly a little low. On NT/2000/XP the only limit is system memory, as far as I know.

As any listbox it can only hold 32K entries (actually, I believe it's 32767). Try searching MSDN for Virtual Listbox. IIRC Paul wrote a Virtual List Control for Win3.x (or was it Win9x?) "a few years" ago.

is anybody could explai me how i could create an automation which could simply open a specific workbook, a specific worksheet, update the data(using shift+F9) and close it. I would like to create this automation so that i could have a button in my dlg box app, when pushed it will update the data i need for my calculations???
thanks in advance

Look in the MSDN Article ID Q192348
You can find it all that you need, the explanetion is for Excel 97 but it can help you with other versions..
Best regards. And Happy Weekend

Hello,
When an application states it requires 32MB of memory to run, how did the developer determine this? Is there a clear cut way or are they just guessing? Any ideas?
Thanks!
Derek

I just guess. The total memory ammount depends on what other software you are running.
There are articles on MSDN that will tell you how to do this, but, in a real world, just try your software on different configurations and recommend to your users what they feel comfortable.

I have a dlg application in which i would like to put 2 check box. For each check box there is a boolean variable, i would like to use those variables so that my app could call the right function when one of this check box is flagged.
But, when i try to compile my code i have this kind of warning message:
warning c4800:"int":forcing value to bool "true" or "false"(performance warning)
So, i don't know if it's really a big pb. Perhaps i should use another type of button as a radio button, i don't know!
Thanks in advance for your help.

You can safely ignore this warning, or you can get rid of it by changing the type of variables from bool to int.
|
|
|
|
|
Please, post a code excerpt that raises the warning.
Probably, you're doing something like this:
int b;
b = true;
and you should be doing this:
bool b;
b = true;
Tip: press now the reset button to test your memory.

first i post the function which use it:
double EuropeanSwaption::CallOrPutEuropeanSwaption(COleDateTime StartDate,COleDateTime SwaptionEndDate,COleDateTime SwapEndDate,double Strike,int BaseAnnuelle,double Nominal,int Periodicity,_variant_t RateTable,_variant_t VolatilitySurface,bool CheckPayeuse,bool CheckReceveuse)
{
double Price;
if(CheckPayeuse==TRUE && CheckReceveuse==FALSE)
Price=CallEuropeanSwaption( StartDate, SwaptionEndDate,SwapEndDate,Strike,BaseAnnuelle,Nominal,Periodicity,RateTable,VolatilitySurface);
if(CheckPayeuse==FALSE && CheckReceveuse==TRUE)
Price=PutEuropeanSwaption( StartDate, SwaptionEndDate,SwapEndDate,Strike,BaseAnnuelle,Nominal,Periodicity,RateTable,VolatilitySurface);
if(CheckPayeuse==TRUE && CheckReceveuse==TRUE||CheckPayeuse==FALSE && CheckReceveuse==FALSE)
AfxMessageBox("Il faudrait peut être faire un choix!!");
return Price;
}
this first function is used in the calculation part.
Now i could show a sample coming from the the dlg code, i just post the line which call the function described above:
m_dlgPrice=eur.CallOrPutEuropeanSwaption(m_dlgStartDate,m_dlgSwaptionEndDate,m_dlgSwapEndDate,m_dlgStrike,m_dlgModeDate,m_dlgNominal,Periodicity,"TauxZCEURO","SurfaceVolatilite",m_dlgPayeuse,m_dlgReceveuse);
where eur is an EuropeanSwaption object, and m_dlgPayeuse, m_dlgReceveuse are the 2 variables linked to the 2 check box put in the dlgbox.
