use PostThreadMessage(WM_QUIT, 0, 0);

Shamelessly ripped from Chris Becke:
PostQuitMessage() is typically called to terminate
a UI thread, and UI threads typically need to be terminated when all the
windows depending on the thread have been destroyed.
In situations when there is one frame or parent window the PostQuitMessage
is placed somewhere in the windows destruction code. Either in a message
handler: WM_DESTROY, WM_NCDESTROY, or in some c++ function that gets called
when the window is destroyed - prehaps even the destructor.
Sometimes you might have a situation where more than one top-level window
can exist on the UI thread. In that case you want to do some refrence
counting or some other system - every WM_CREATE or ctor increases a ref
count, every WM_DESTROY, OnHesDeadJim, or dtor the ref count is decreased.
When it hits zero all windows are dead and PostQuitMEssage is called to
terminate the UI thread.
Basically there are many ways to kill a UI thread, and to a large degree the
method used will cahnge according to the requirements of the class
library(s) used and other enviromental constraints.

Thanks.

Hi
I am currently building an app that maintains a number of objects of a certain class, and the app performs computationally heavy calculations to determine the state of each object. The state for each object is determined by a number of variables: e.g. variables A, B, C, and D. However, since some of the variables, e.g. variable A is actually identical for all objects, I am now implementing A as a private static variable with a public accessor function. This way, I think I can save some computation and storage space.
My question is: is this the correct way to implement the class? Is building a base class and deriving from it better than my current solution?
Thanks!

hi indrawati,
in your case, the important thing is that what do your variables do. if there are required to be common for all the objects of the particular class, ie they share the same values, then u will have to use them as static. if this is the case then there should be no problem in the design

I am developing an application in VC++. I am using Read function of CStdioFile class to read Html files and storing the file contents in CString object. Special characters like TM, are being replaced by three characters â„¢ What can be the reason? & how to read such characters in VC++ appliction.

Read() is actually a method of the CFile class. Since .html files are just text, shouldn't you be using CStdioFile's ReadString() method instead? I guess it depends on what you are doing with the data after it has been read.

Hi David,
You are right. CFile has Read function and CStdioFile is derived from CFile. I used ReadString function of CStdioFile also. But still I am not able to read the special character ™ properly. This character is present in Html file name and its corresponding folder name. So this character is also present in Html file contents as the folder name appears in Html file many times.
I want to get the images present in Html file. I am parsing Html files and SRC attributes of tags. But the relative path contains ™ character. After reading this Html file by using any method (Read/ReadString), this character splits into three characters â„¢ and relative path of image becomes invalid and program fails. So I want to know why this happens and is there a workaround for this problems.
Thanks & regards,
Arvind

Hi David,
For example you can browse the following link and save this as an Html file on your Hard Disk. You will find ™ character in it. Try to open this file by using CStdioFile/CFile class, and read the contents of file. ™ character splits into three characters. If you find any solution please let me know.

One more strange observation. If you try to save this file at another location in Hard disk (by using save as option), it can't save. I think becuase ™ character, this is happening.
Thanks and regards,
Arvind

This worked fine for me:
CFile file("c:\\3M Aerospace 3M™ Heavy Duty Cable Ties.htm", CFile::modeRead);
TCHAR sBuffer[1024];
DWORD dwBytesRead;
do
{
dwBytesRead = file.Read(sBuffer, sizeof(sBuffer) * sizeof(TCHAR));
} while (dwBytesRead > 0);
file.Close();While the VS editor did indeed show a "block" character right after the second 3M, its value was interpreted correctly.

Nope, saved fine.

Hello,
Trying to write a program in C++ that will do the following:
1)Input a string of characters from the keyboard, (up to 20 char max.) Allow the user to enter up to the length of the string (20).
2) Print the string out as entered.
3) Count the number of vowels (incl. upper and lower case)
40 Count number of spaces in the string
Count the number of digits in the string
60 If the string does not include vowels, spaces or digits, then print a zero for its count.
My background is not in C++ so if anyone could help this would be appreciated.

I supposed you are writing a console application right?

Use _getch. It gets a character from the console without displaying it. You can then use it to limit the number of characters user can enter.

cout

Hmm, what u mean?
bctuthrcls wrote:
40 Count number of spaces in the string
Use a for loop to check for the space character
bctuthrcls wrote:

Same as above. Use isdigit(...)

Brother this is code for your program
hope it work
<br />
void main();<br />
{<br />
int nLength=0;<br />
char *szData;<br />
cout<<"\nEnter he Length of string : ";<br />
cin>>nLength;<br />
szData=new char[nlength+1];<br />
getline(szData,nLength);<br />
cout<<endl<<"YOu have enter : "<<szData;<br />
int Vowels=0,Spaces=0,Digit=0; <br />
char ch=0;<br />
for(int i=0;i<nlength;i++)<br />
{<br />
if(isDigit(szData[i]))Digit++;<br />
if(szData[i]==char(32))Spaces++;<br />
ch=toupper(szdata[i]);<br />
if((ch=='A')||(ch=='E')||(ch=='I')||(ch=='O')||(ch=='U'))Vowels++;<br />
}<br />
cout<<endl<<"NO Of Vowels : "<<Vowels;<br />
cout<<endl<<"NO Of Spaces : "<<Spaces;<br />
cout<<endl<<"NO Of Digits : "<<Digit;<br />
<br />
getch();<br />
}
pls remove some compiler error if occur

When I add the object library for MS Word the file "msword.h" isn't created.
The example uses "msword8.h", which is for Word 97 (versions 8). The version number will be different; I believe it will be version 11, although I haven't tested it. Try "msword11.h" instead - or look for a similar file in your project directory.

I tried with "msword11.h" too but don't work. In the project directory there aren't files with similar name.
I don't understand where i miss.

When you want automation, you need to read a lot about it. I don't have experience with it myself, but I have written an application calling Word and it doesn't have an msWord.h file.
You have to import a sort of Object or component from your Word program. Every Microsoft Office version has another one. (you can find which one on msdn.)
Only advise I can give you is read and search.
PS: For Office 2003 it's not MSWord11 but MSWORD
I think you need the MSWORD.OLB file (somewhere in your office directory)
good luck and I hope this helps at least a little.

/* I have spent the last few days reading the articles on dlls and am still as lost as when I began.

All I want to do is to place a bitmap into a dll.
Then from my exe call the resource for usage. eg LoadBitmap(IDB_BITMAP)
/* So whats the best way of going about doing this?
Some working sample code would be great
*/
|

off the top of my head
1) call LoadLibrary to load the dll
2) call LoadBitmap passing the handle returned from step 1
HINSTANCE hMyDll = LoadLibrary("Somedllwithbitmap.dll")
ASSERT(hMyDll);
HBITMAP hBmp = ::LoadBitmap(hMyDll, MAKEINTRESOURCE(IDB_SOMEBMP));
ASSERT(hBmp);
CBitmap *pBmp = CBitmap::FromHandle(hBmp);
use pBmp
//clean up not so sure about this bit, check the doco
delete pBmp;
FreeLIbrary(hMyDll);

Ok, I had been doing something similar without success,
maybe I didn't make the dll correctly to start with.
Thanks for your help.

since this a VC++ forum, you can use your VC++ to create a windows dll and export the dll function.
I am sitting in my flame proof buncker, so don't even bother.
by the way, perl stinks.

Hi there,
I have some variable-height controls which need to have some vertically-centered text written on them. My question is: knowing the height the text should occupy, what do I have to do in order to create a point-font?
Thanks a million,
David
