 Dear Mr Bhavani;
Thank you for the help that you have given me in accessing a public variable from anywhere within my application. The problem is that the code did not work at all. The compiler strongly complained when i added these code:
((CDatastructorView *) AfxGetMainWnd())->m_main.Navigate"file://c:/datastructor/lectures/recursion_implementation.htm",0,0,0,0);
CDatastructorView is my view class and m_main is a web-control which i want to use.
The compiler responded as :
:\datastructor\lefttooldlg.cpp(1296) : error C2065: 'CDatastructorView' : undeclared identifier
C:\datastructor\lefttooldlg.cpp(1296) : error C2059: syntax error : ')'
C:\datastructor\lefttooldlg.cpp(1296) : error C2059: syntax error : ')'
Could you please help me out because i am still pretty at lost.

In what file did you define the user type CDatastructorView?? Just include that .h file in the lefttooldlg.cpp.

at the top of lefttooldlg.cpp add
#include "..." //... = header file where CDatastructorView is defined
and your call should be:
((CDatastructorView *) AfxGetMainWnd())->m_main.Navigate("file://c:/datastructor/lectures/recursion_implementation.htm",0,0,0,0);

I need a CListCtrl derived class using owner-drawn report-mode but with '1 virtual column' that always stretches the entire viewable area.
Any ideas ?
|
|
|
|
|
then you would have to draw the columnd AFAIK...it would make your a job a lot easier to use custom draw though...
Cheers 
How do I print my voice mail?

I'm ok with that, I already have a full-fledged Owner-Drawn CListCtrl.
My only problem is that in a certain configuration I'd like to move to a 'non column-based' layout and maintain my owner-drawn capabilities, this doesn't seem to be supported in a standard manner.

you could use InsertColumn only once and setting up the width of the control, it should use all the control's width and only in one column.

Hi to everyone reading this...
I have noticed that when an EditBox has the option singleline then if u add a notification handling function to it (lets say for the event EN_UPDATE ) and u call SetWindowText inside the function u instantly u receive a second notificatio and again and again.....
If though the EditBox has the option multiline the above behavior does not take place. Insted the notification arrives only once, SetWindowText sets the new text to the EditBox and the notification handling function exits.
Does anybody know why this deference exists? Does it serve a purpose?
In a single line EditBox how can i alter the text typed before it is displayed?
Thanks in advance for helping....

Just curious, but when you set the text for a single line control, how many r\n\ were there?
How do I print my voice mail?
|
|
|
|
|
Well the text i'm printing with SetWindowText is just one single line thus the editbox doesn't contain any \r\n characters.
What do u mean "How do I print my voice mail?".

Hi all,
I was wondering if someone can shed some insight into this problem i'm having. I am decent with C++ but very new to managed C++.
I have a managed c++ class library which wraps some unmanaged c++ code. At the moment i'm using a test harness which is a C++.NET Windows Forms Application project. (I have also tried writing the Test harness in VB.NET and C# but got the same error).
What happens is that when i start up the test harness, the form loads, but when i click the button to run the function i am testing from the class library, i get the error i have pasted below.
I have tried explicitly defining the path of the class library's output directory using the Reference Path project property, and have also tried copying the project output manually into the test harness' executable dir. ANd now i'm not sure what else to try!
Thanks in advance for any help/info..

The error output is below:
----
'TestImagePreviewReaderCPP.exe': Loaded 'C:\Development\projects\PerforceRoot\CodeLibrary\ImagePreviewReader\Debug\ImagePreviewReader.dll', Symbols loaded.
'TestImagePreviewReaderCPP.exe': Unloaded 'C:\Development\projects\PerforceRoot\CodeLibrary\ImagePreviewReader\Debug\ImagePreviewReader.dll'
An unhandled exception of type 'System.IO.FileNotFoundException' occurred in system.windows.forms.dll
Additional information: File or assembly name ImagePreviewReader, or one of its dependencies, was not found.

I am using VS-6.0 & C; Win-2000. I want to use the function SetDCBrushColor but when I compile the code I'm told this is an undeclared identifier. MSDN says that this is declared in Wingdi.h (use Windows.h) and is in GDI32.lib -- even though I am doing this (started with Windows.h already, and have tried adding Wingdi.h; GDI32.lib is in my project settings) I'm still not having luck. Any advice?
(this has happened on two machines, one set up at work and one I did at home ; if I open Wingdi.h I can see the function declared...but apparently my project does not?)

You need to have the _WIN32_WINNT macro defined as 0x500 or higher in order to use that function. The best place to do that is in your stdafx.h file.
#define _WIN32_WINNT 0x500

Hi,
I am totally new to creating dlls . I've one doubt to be solved urgently --
For Windows -
There is a application which loads a dll, calls the dll's entry points and puts some data into the dll's data structures. Now there is another application which again loads the same dll and calls the dlls' entry point.
Is it possible to do the above in VC++. I am not aware so I may have put some terms very wrong. Pls correct me for that..
Any response greatly appreciated...
Regards

Your thought is absolutely vaild becasue each application loads the dll in its process space. I think it will work.

I'm not sure to understand what you want to do.
Do you want 2 programs to use the same function of a dll at the same time or do you want the first program to modify datas that the second will use ?
The first is always possible.
The second is possible if:
- you use global variables (to stock your datas)
- the dll must "stay alive": you have to run the second program before the first one unloads the dll.It is very important otherwise your datas will be lost. There must be another way to do it better, but I know it works as I did it this way...
If the question was something else , then tell it...

I am writing some fairly simple code for a uni assignment and I have this error come up in a couple of instances "Declaration terminated incorrectly", I have checked the code over many times and just can't seem to work out the problem. The error occurs when I compile barDrv.cpp, and the error is in CustomerOrder.h on line 10. Here the code for the two files:
barDrv.cpp
//File: barDrv.cpp
//Test harness for assignment
#include <iostream>
#include "CustomerOrder.h"
#include "Bar.h"
static const int MAX_ITEMS_IN_CUSTOMER_ORDER = 15;
static const int MAX_ITEMS_IN_BAR_MENU = 40;
int main()
{
char choice;
int nextMenu = 1;
Bar theBar(MAX_ITEMS_IN_BAR_MENU);
CustomerOrder theCustomerOrder(MAX_ITEMS_IN_CUSTOMER_ORDER);
theBar.maintainStock();
do
{
theBar.printBar();
cin>>choice;
switch(choice)
{
case 'Q':
cout<<"Thankyou for using Tunerica Corporations software!";
nextMenu = 0;
case 'I':
int number;
theBar.printInclude();
cin>>number;
theCustomerOrder.includeItem(number, theBar);
case 'X':
int number2;
theCustomerOrder.printExclude();
cin>>number2;
theCustomerOrder.excludeItem(number2);
case 'P':
char whatToDo;
theCustomerOrder.printInvoice();
cin>>whatToDo;
if (whatToDo == 'Y')
theCustomerOrder.~CustomerOrder();
else
nextMenu = 0;
}
}while(nextMenu!=0);
return 0;
}
CustomerOrder.h
//File CustomerOrder.h
//Interface for the CustomerOrder class
#ifndef CUSTOMERORDER_H
#define CUSTOMERORDER_H
#include <string>
#include "Bar.h"
using namespace std; <<<<<-Where the error apparently is
class CustomerOrder
{
public:
CustomerOrder(int maxItems);
~CustomerOrder();
void includeItem(int choice, Bar aBar);
void excludeItem(int choice);
void printExclude();
void printInvoice();
private:
int numInInvoice;
int numItemsInvoice;
double calcTotal();
Item * * invoice;
};
#endif
Any help or suggestions would be greatly appreciated.
Thanks in advance.

1) Start by moving "using namespace std;" to the source file instead of the header file, because the header file is not the file that is using it (amongst other reasons).
2) Except that the syntax is C++, it looks like you think the case statement works that same as the simular constuct in VB. You must place a "break;" at the end of each case and before the next case.
3) This "theCustomerOrder.~CustomerOrder();" is a call to the destuctor of "theCustomerOrder", do not do this (EVER!). I've never seen anyone do this before!!!
Once you fix this problems, you may see your error disapear!
Good Luck!

Thanks for the reply, ended up figuring out what the problem was, I left the semi colon from the end of the Bar class.

 Hi. I cant seem to find anything simple that will allow me to display a JGP (or Bitmap) on a dialog window. All I want to do is display 1 image on a dialog, thats it. If anybody has some code they would like to share to do this, that would be great!! I'm using MS VC++ (MFC exe).
Thanks alot!!

I need to translate this code from Ansi C to C++, it copies everything from the file (except EOF or /n) to the string temp
<br />
string temp;<br />
<br />
FILE *arch;<br />
char c;<br />
<br />
arch=fopen(s,"r");
<br />
while (!feof(arch))<br />
{<br />
c=fgetc(arch);<br />
if ((c!=EOF) && (c!='\n'))<br />
temp=temp+c;<br />
}<br />
fclose (arch);<br />
i know the first line may be:
ifstream arch (s);
thanks
hope you can help me!!
