Wow, you must have a massive screen to be able to display that many windows and still be able to read them.
I think you should rethink how you are displaying your data to your user. there is absolutely no need to keep that many windows around. One solution would be to create only as many 'CmyView's as you can display in the parent view at one time, then simply swap the data in and out depending on the position of the scroll bar. Even with the 16 bit limit of the WM_VSCROLL message that would give you a limit of 32767 views, if you used Get/SetScrollInfo() instead of WM_VSCROLL you could have a limit of 2^31 views without the problems you are encountering with more than a mere 1800 views.

Friends,
I am having a strange problem with VC 7.0 while assigning a variable with an edit ctrl on the dialog box. Here is the description:
I dropped an edit control on the dialog box and then right click on that edit control in order to add a variable of type int. I also give min and max values to the variable. The problem is that, the variable is added in the header file of dialog, but there is no entry of this variable in DoDataExchange.
This is something different from VC++ 6.0. Can any onw tell me what is the problem ?

Hi,
I want to open a .doc file using SHellExecuteEx. How do I do it if I want the file to be opened by an WINWORD instance that is already running, and how do I make it open with a new instance or WINWORD?
thanks!

Here, try this code with the following comments:
GetFileName returns a path and name to the document to be opened.
FindAdobeAcrobat and FindWinWord return the paths to those applications.
see the documentation on _spawnlp for more info.
void COpenDoc::DoOpenDoc(bool bIsReadOnly)
{
CDTApp* pApp = (CDTApp*)AfxGetApp();
char *args[4];
CString strAppPath;
CString requestName = GetFileName(bIsReadOnly); // get the correct doc, and copies it as necessary.
requestName = requestName.MakeLower();
if(requestName.Find(".pdf",0)!=-1)
strAppPath = FindAdobeAcrobat();
else
strAppPath = FindWinWord();
args[0] = strAppPath.GetBuffer(255);
args[1] = requestName.GetBuffer(255);
args[2] = requestName.GetBuffer(255);
requestName = '\"' + requestName + '\"';
if(!strAppPath.IsEmpty() && !requestName.IsEmpty())
{
int j = _spawnlp(_P_NOWAIT, strAppPath,_T(requestName),_T(requestName),NULL);
j = errno; // here we get the error is something fails.
switch(j){
case ENOMEM: AfxMessageBox(AFX_IDP_FAILED_MEMORY_ALLOC); // NOT ENOUGH MEMORY
break;
default : {
if(j!=0)
{
CString strErr;
strErr.Format("Secondary application path = %s\nRequest Filename = %s",strAppPath,requestName);
pApp->LogGeneralError(strErr);
}
break;
}
}
}
this->OnCancel(); // close out diaolg
}

I dont see ShellExecute/Ex used anywhere in your code snippet, do you? I am looking for an example that uses ShellExecuteEx. Do you know about it?
thanks!

Hi everybody, I'm a beginner and I'm writing somthing like this
double *Interesse ,*Capitale, *TassoInteresse, *Intervallo, *Totale;
*Interesse = *(Capitale) * (*TassoInteresse) * (*Intervallo) /36500;
*Totale = *Capitale + *Interesse;
usually this work good but with some value I have rounding problem
like this:
*Capitale = 111111;
*TassoInteresse = 2.5;
*Intervallo = 365;
before converting to string;
*Interesse = 2777.7750000000001
*Totale = 113888.77499999999
after conversion:
2777.78
113.888.77
How can I avoid this?
Thanks in advance.

This is the normal floating point behaviour in all/most computer languages.
There are numerous ways to display floating point number rounded off to a fixed value, just google for them. ( for example : http://support.microsoft.com/default.aspx?scid=kb;en-us;196652 )
but, if you need to use those values, don't rely on the text display, always keep a "real" value, i.e. if your calculation result in 2777.7750000000001, don't use the rounded value, because you will loose precision in the long run.

I don't understand what you are asking.
You have a pointer to a double and set its value and that works well, but then you are changing the value when you do the conversion and don't like the result?
I'd use another variable to hold the result of the conversion then you don't change the value of the original double assignment.
If you want to format the string result of the coversion then that is a different question.
I'd suggest not using pointers to start with until you understand what is going on unless the exercise you are doing requires you to use pointers. I'd also suggest a text like C++ from the ground up to learn the basics.

Try with this:
char sInteresse[30], sTotale[30];
sprintf(sInteresse, "%14.14f", Interesse);
sprintf(sTotale, "%14.14f", Totale);
|
|

I use _fcvt() to convert double to string .
i'm not rounding double values.
double values are in previous topic
when converted the result is
111111 + 2777.78 = 113888.77 
Thanks.

Hi all,
Please guide me.i am working in vc++ 6.0.Do i need to shift to .net?(i don't have any idea of .net).What are the areas in which i can make my career using vc++ platform.Is my fear about insecurity(if i don't shift to .net) well founded?
Regards,
Ankush

using Visual Studio .NET (2002, 2003, 2005) don't make you a ".NET programmer", because you can do whatever you were doing with VC++6 with it... if your project uses MFC, then migrate to VS.NET will use the newsion of the MFC library, not the framework .NET.
however, you have to take note that now, Visual Studio 6 support has been abbandonned by microsoft...

Hi Ankush
I am the same vc++ prog and plannig to
get some .net exams .
As i think desktop applications will
move to .net
But for certain things like DDK will
be same and vc++ is must for it.
U can also try to learn some thing
which develop crossplatform applications.
because that is the future .

Its All depend on you! actaully I too working totally in Unmanaged Code ... i don't know even ABC of managed Code... its actually all depends on situation but frankly speaking, India doesn't have enough job for vc++.net proffessional.

totally depend on you... let me introduce some active member of this forum :- Mr David Crow :- Storage related field,Nishant Shivakumar working with dundas on vc++ related stuff, Priyank used to do Image processing in VC++.. Vivek is using Tapi.. I forget about Tox . Vikas is working in Embedded using vc++.. sunit working on network application. cedric on bluetooth tech... Is I left some one?.. there are numerous field for vc++ and related stuff.. you have to choose from them

alok do you remember what was my second question at you??. the same issue is roaming around in everybody's(most people's) mind. but you know, i started my career with .net but i found some kind of attraction in "VC++", and started doing few smaller things(naturally torturing mr.alok), and my boss found something good in me and moved to me this domain. now i've to study not only VC++ but also the Computer-telephony-Integration (CTI). i've done quite useful things in here. but still i feel insecure.. without learning dot net. may be i'll have take a strong decision soon. i'm scared too buddy

but i tell u VC++ is the real programming language. it talks straight to the machine. and not any Virtual Machine  .i always wanted to call myself VC++ programmer rather than dot net programmer. hey still there are lots of scope for VC++ in India. have you heard about HUGES Software? they are hiring a lot. once you become strong in VC++. you'll be able to work on any domain. i'm finding it easy to manage my new CTI challenge. and also have in mind that once you conquer VC++, other languages are nothing for you. you can learn too fast. trust me.

So buddy you mean right now i should focus myself on vc++.(I am a 2005 passed out comp.engg. graduate working in vc++ 6.0).After i am strong enough, i should move to .net.How much time in vc++ will be okay.
thanks for guidance...

ya you can do that. but it'll be good if you atleast study concepts about .net side by side.(if not to the implementaion level), try few samples at home, and keep you updated. during office time, you make full of the time for VC++. even i'm not satisfied with my learning curve, i need to work hard a lot. certainly VC++ will give you a strong foundation for your programming career.
Ankush Mehta wrote: How much time in vc++ will be okay.
It depends on your capabilites and commitment, for people like alok, i guess 6 months would be enough to get grip of VC++.
