The double colons force the compiler to look in the global namespace for the function - without them it will always look in the current class first, meaning that it finds the HtmlHelp() method rather than the global function.
To link with HtmlHelp.lib, you must add it to the list of libraries in the project settings (Project->Settings->Link) - it does not automatically link with all libraries in the lib directory.

I'm creating an SDI application using the CListView class as the base view, and I'm having a problem knowing when I should do things like InsertColumn(). If I use the OnInitialUpdate() method, columns get inserted every time that a new document gets created. When I try to use the OnCreate() method, I get an exception stating that the main frame has not yet been created (note that I'm getting a pointer to the main frame object to set some window "snap" settings).
Is there a method for a view that gets called only once upon program startup, but after all the windows have finished their creation state? I basically want to know where I should insert columns and do other, one-time initialization stuff.
Any ideas?
Thanks,

How about just using a flag bListCtrlInitialized in OnInitialUpdate() to ensure it gets done just once?

Yes - I've thought of that, and it certainly would work. But it just seems so cheap...

I am trying to create a color palette that will allow someone to pick what color of text they want. I can't seem to find anything to help me out on this. Any ideas?
|
|
|
|
|
Use the ChooseColor function to create a dialog box where you can pick a color.

I have a string that is :
string myString ="Appliance.Oven.Heater";<br />
string commandString="Run:appladdr:TurnOn:150seconds"; In commandString I want to replace "appladdr" with myString .
for the final string to be
Run:Appliance.Oven.Heater:TurnOn:150seconds
I was getting a memory error using CString .
when I did
CString finalString = commandString.c_str();<br />
finalString.replace("appladdr",myString.c_str());
What am i doing wrong ?
I would like to do this using STL itself.

My good deed of the day: 
#include <iostream.h>
#include <string>
using namespace std;
void main()
{
string myString ="Appliance.Oven.Heater";
string commandString="Run:appladdr:TurnOn:150seconds";
commandString.insert(4, myString.c_str());
commandString.replace(24, 8, "");
cout << commandString.c_str() << endl;
}

Using STL:
int nPos = commandString.find( "appladdr" );
if ( nPos != string::npos ) {
commandString.replace( nPos, strlen("appladdr"), myString );
}
The MFC code looks right though - what exactly is the memory error that you are getting, and on which line?

I am doing all of the MFC in thread functions . I do not know if that is a problem . I am getting memory read errors .
|
|

Are you sharing the string objects between threads? MFC objects should never be used in more than one thread, and the default STL string implementation provided with VC6 is not threadsafe for reading.

Hello CPIAN_GURUS! 
I've placed a WebBrowser2 control (the active x that comes with VC++6 (Project >> Add To Project >> Components & Controls >>...)) In a dialog and in an array of property pages...
The one that is in the dialog works perfectly, but the one that is in the array of property pages don't appear... the strange thing is that I hear the sound of the page loaded (the 'click' that sounds when a page has been loaded completely) but I cannot see the control...  
Any idea? 
Do you think I'm missing something?
TYIA!!!

|

Perhaps the one on the property page is incorrectly positioned/sized?

I don't know, but this[^] article shows to craft a combobox whose droplist is always wide enough to display the widest string in the combobox.

How do you put controls into a non-doc/view MDI child window?
-- Steve
|
|
|
|
|
Either create a dialog, and put the controls via the resource editor, and create the dialog as a modeless dialog in the child window , or create each individual controls manually in the child window.

I'm not expirianced in using MFC, so I need help in working with CStringList class
I'm not eble to set or get elements of this collection.
I need an example.
Thank you

Here's an example. Btw, see if CStringArray (a directly accessible dynamic array of CStrings) is more suited to your needs. I tend to use that because it's more efficient. Of course if you need a list, then CStringList is the non-STL way to go.
CStringList myStringList;
CString strFirst = "First";
CString strSecond = "Second";
CString strThird = "Third";
POSITION pos = myStringList.GetHeadPosition();
pos = myStringList.InsertAfter (pos, &strFirst);
pos = myStringList.InsertAfter (pos, &strSecond);
pos = myStringList.InsertAfter (pos, &strThird);
pos = myStringList.GetHeadPosition();
while (pos != NULL) {
CString* pString = (CString *) myStringList.GetNext (pos);
TRACE ("Element = %s\n", *pString);
}

(using VC++6, MFC,... )

I'm now displaying a webcontrol (CWebBrowser2, from the components) in my UI; it's in a CWnd, inside a floating window; I have two floating window, each display some UI, one of them receive the webcontrol; the other floating window contain tree controls, buttons, ...
If I really create the the webcontrol, the rest of the UI doesn't gets initialized properly, they don't get resized, they don't receive an appropriate WM_SIZE.
If I don't create the webcontrol, the UI is perfect, I receive 2 size messages, one, I think is ok, of cx=0 and cy=0, and the other size with the good value (cx, and cy are normal values, the real size.
Also, if the floating windows are docked, everything gets displayed as expected ?
I don't know if it's because the control takes a long time to create ? or if it's eating messages intended to the parent window ?
Anyone have some clues ?
Thanks.

Hi!
I've the following code:
In my CDocument based class:
//Scripting support
class CScript
{
public:
CString sString0, sString1, sString2, sString3, sString4;
int i0, i1, i2, iID;
};
//Script IDs
#define MOVE_PLAYER 0
#define TEXTBOX 1
#define CHOICE_TEXTBOX 2
#define GIVE_ITEM 3
#define MOVE_OBJECT 4
#define HAS_ITEM 5
#define IF_ELSE 6
//End scripting
class CMyMap
{
public:
CMyMap()
{x=0; y=0; id=0; iMax[0]=0; iMax[1]=0; iMax[2]=0; iHitpoints=0; bWalk=true;};
CMyMap(int nx, int ny, int nid)
{x=nx; y=ny; id=nid; iMax[0]=0; iMax[1]=0; iMax[2]=0; iHitpoints=0; bWalk=true;};
int x, y, id, iMax[3], iHitpoints;
bool bMoveable, bDestroyable, bTileSave, bWalk;
CScript cs_arrayScript[3][100];
};
class CTheEditDoc : public CDocument
{
[...]
public:
CArray<CMyMap, CMyMap&> dv_arrayMaps;
// Overrides
void Serialize(CArchive &ar);
[...]
}
void CTheEditDoc ::Serialize(CArchive &ar)
{
CDocument::Serialize(ar);
if (ar.IsStoring())
{
dv_arrayMaps.Serialize(ar);
}
else
{
dv_arrayMaps.Serialize(ar);
}
UpdateAllViews(NULL);
}
My problem 0:
When saving my document everything works fine, but when it comes to reloading it cs_arrayScript[3][100] is filled with waste (all other variables are loaded corectly). Is the Serialize function of CArray unable to serialize my 2D-array properly?
My problem 1:
While the User works with my app the CArray dv_arrayMaps is filled. After some CMyMaps (I think about 10-15) are pushed into it the app slows down a whole step. Is there a way around it? Am I handling to much data?
[I tried dv_arrayMaps.FreeExtra()]
