hi
I tried some simple programs using collection classes of c++
like and <list>most of the programs gives 26 warnings but no errors,
Though the program works i am not able to understand the warnings
These are the warnings------------------
Compiling...
AGComponent.cpp

You need to put a pragma at the top of your stdafx to stop these stupid warnings - they relate to the innefficiency of VC, not anything wrong with your code or the STL. The pragma is something like
#pragma disable 4786
but my syntax is probably wrong. The pragma tells the compiler to ignore this warning.

What you mean is:

Hi,
I'm deriving a class off of the WTL's CCommandBarCtrlImpl in an attempt to
recreate the new look of Office XP or DevStudio.NET. I'm running into a
problem, however, as I cannot seem to get the WM_DRAWITEM message sent to
draw the 'root' menus on the screen ( those which appear at app startup ).
I've overridden the AttachMenu function as follows to change the base menus
to be owner drawn ( the base command bar control doesn't ):
long CCoolMenu::AttachMenu ( HMENU hMenu ) {
ATLASSERT(::IsMenu(hMenu));
for ( int i = 0; i < ::GetMenuItemCount ( hMenu ); i++ ) {
MENUITEMINFO mii;
char menuString [MAX_MENU_STRING];
mii.fMask = MIIM_CHECKMARKS | MIIM_DATA | MIIM_ID | MIIM_STATE | MIIM_SUBMENU | MIIM_TYPE;
mii.fType = MFT_STRING;
mii.dwTypeData = menuString;
mii.cch = MAX_MENU_STRING;
mii.cbSize = sizeof ( mii );
::GetMenuItemInfo ( hMenu, i, TRUE, &mii );
int errorval = GetLastError();
mii.fType = MFT_OWNERDRAW;
::SetMenuItemInfo( hMenu, i, TRUE, &mii );
errorval = GetLastError();
}
CCommandBarCtrlImpl<ccoolmenu>::AttachMenu( hMenu );
return 0;
}
This seems to almost work. The errorval variable thrown in to test shows
that the menu is being set without error. The app starts up, and no menu
information is displayed at the top. However, I put breakpoints in the
CCommandCtrlImpl OnDrawItem and OnMeasureItem functions, and they are only
receiving messages when I click to open a submenu. I have also intercepted
the WM_DRAWITEM and WM_MEASUREITEM commands in my own class, with the same
results. So now I am confused. Is it possible to ownerdraw the root menu's
at all? Or will I be forced to do something more drastic?
Thanks, this is starting to give me a headache...

The sample mentioned doesn't receive messages for the root menu's either. There must be some way to receive DrawItem and MeasureItem messages for the root menus - isn't there?

I have a workspace that consists of an MDI project as one project and another GUI project that is used in the MDI project as its GUI elements.
However, anytime I want to trace a problem in the GUI project from the MDI project, I get the "Some breakpoints can not be reached error".
Since I need to launch the MDI project and input paramters first before launching the the Dialogs in the GUI project, I am not sure what to do?
How would you debug something like this?
|
|
|
|
|
Put them in the projects in the same workspace set all the breakpoints and start debugging. some of the breakpoints will get disabled but you will probably get stopped at one of your breakpoints in your MDI or at the beginning of the MDI application and you can then renable the breakpoints in the other GUI project in the workspace via the breakpoints dialog (Ctrl-B).
Cheers,
-Erik

What is meant by the term 'regular expression'. I see it alot but I'm not clear as to what it means. Thanks,

first result in a Google search:
A regular expression is a way for a computer user to express how a computer program should look for a specified pattern in text. The user of a regular expression can then tell the program what it is to do when matching patterns are found - for example, print out each line in which a match is found or substitute another text sequence where any match occurs.
....
best known tool is grep used in UNIX systems and also offered as a separate utility program for Windows and other operating systems.

Hi
I want to add a button to the IE-toolbar.
I read the article on MSDN:
http://msdn.microsoft.com/library/default.asp?url=/workshop/browser/ext/tutorials/button.asp
The creation of the necessary registry-keys is no problem, but there are mentioned
to COM-function:
IOleCommandTarget
and
IObjectWithSite
Unfortunately I have ABSOLUTELY NO IDEA what to do with them, the help didn't take me any further.
Could you explain me or give me some URL on how to use it?
regards

To add a button to IE you don't have to do any com programming. If you want the button to do something, you can write script, write a exe to execute, or develop a IE addin like a toolbar or an explorer bar. If you're looking to do the later, read my latest tutorial in the ATL section.
Cheers,
-Erik

What I want to do is as follows:
When the user clicks on the button a popup-menu should appear.
When the user clicks on a menu-item some text should be inserted into the control of the current html-site, which has the focus.
How can I start?
The button is created already

You can do that quite simply with custom draw. Look up "NM_CUSTOMDRAW (tree view)" in MSDN.

Hi!
I'm writing an app that tries to capture OutputDebugString()
messages from another app I've written. I propery get
DEBUG_EVENTs from the other app and I make sure that I work
with OUTPUT_DEBUG_STRING_EVENTs, but when I try to get the
string data by calling ReadProcessMemory(), I get nothing
but garbage.
I've got a proper handle to the process, the pointer to the
string data provided by the DEBUG_EVENT and a pointer to
an appropriately sized data buffer to dump the data in, but
like I said, I get nothing but garbage. I have no idea what
to do. Does anybody have any idea?

Hi there,
I have an application that has upwards of 20 classes and a lot of these
classes need to use a method in one another to get the whole thing going.
I was wondering whether the following practice of mine is considering
bad programming/design habit and there is a better way of doing it:
I tend to include header files of any class i need in any given file
and then, call the member functions of the class as following:
CClass2 x2;
x2.print();
I was wondering if I do this too many times, whether it would cause
a problem somewhere in the code or is this an acceptable practice?
|

Without knowing what the default CClass2 constructor does, your question cannot be answered. Generally speaking, there is no harm in declaring a class as a local variable. In fact, IMHO, that is the sort of design you should generally strive for. However, if your default ctor is doing a lot of work initializing the class you might rather have it as a member of the class so that it is only initialized once.
class myclass
{
private:
CClass2 m_x2;
};
void myclass::somemethod()
{
m_x2.print();
}

Hi,
I've created a button dynamically but I only know how to respond to the button by assigning a handler using the wizard, but how do I go about it now?!
