I have a floating controlbar which is set to its maximum size in a high resolution screen. when I reduced the screeen resolution my controlbar does not automatically resize to the current settings as the cframewnd does.
How to make a control bar respond to screen resolution changes?
Thanks.

Hello,
I have two question-the first is about MessageBox and the second is about pointing.
1) Whaen I'm trying to use simple MessageBox
MessageBox("hello");
it writes me: error C2660: 'MessageBoxA' : function does not take 1 arguments
but as I know the other arguments are optional, so what is the problem? and why it writes MessageBoxA?
2) I asked a question one or two days ago about my Tic_Tac_Toe project, and have another:
here is the code:Code[^]
Some introduction:
T1/T is a Tic_Tac_Toe object (the class is defined from line 2-12).
PointersToNodes is a pointers array to Tic_Tac_Toe objects.
currentCaseVector is an array of the current board.
and buildNewTree is a function which returns adress of a Tic_Tac_Toe object(line 78).
When I'm running the project it thorows me an error at line 40:
c = T->PointersToNodes[1]->currentCaseVector[i];(c is char).
the error is(I uploaded a picture with the error):
http://img241.imageshack.us/img241/2323/bugmq7.jpg[^]
And those who can't see the picture so the error is:Unhandled exception at 0x004bebbf in Self_Learning_Tic_Tac_Toe.exe: 0xC0000005: Access violation reading location 0xcdcdcdcd.
Why does the error occurs? and how can I fix it?
Thank you!

MessageBox function take 4 parameters.
It's declared as:
int MessageBox(HWND hWnd,
LPCTSTR lpText,
LPCTSTR lpCaption,
UINT uType
);
MessageBoxA- Windows
MessageBoxW- Unicode //// Correction
On the other hand AfxMessageBox takes only 1 parameter.The other's are default.
int AfxMessageBox(
LPCTSTR lpszText,
UINT nType = MB_OK,
UINT nIDHelp = 0
);
int AFXAPI AfxMessageBox(
UINT nIDPrompt,
UINT nType = MB_OK,
UINT nIDHelp = (UINT
) -1
);

Thank you for the answer for 1 and
What is the problem with the second question? please look at the code in line 40.

wrong, it's the opposite...
A stands for Ansi
W stands for wide characters ; UNICODE then

1. Message function takes 4 paramaters, not 1.
2. 'cdcdcdcd' normaly means uninitialized memory. You create the array here currentCaseVector=new char[9]; But I can't see where you initialize it. try calling memset() first to set the memory to 0.
Also, I don't want to call your code sloppy, but there is very little error checking. You should be initializing your variables and setting them to NULL. Later when you come to use them, you should check first if they are NULL or not.

I'm intializing it in lines 31-32:
for(i=0;i<9;i++)<br />
T->currentCaseVector[i]='b';

No you are not.
for(i=0;i<9;i++)
T->currentCaseVector[i]='b';
for(i=0;i<9;i++)
c = T->PointersToNodes[1]->currentCaseVector[i];
You are initializing each member of the localy created T object. But you are readig the uninitialized members of a pointer to an object of type T, in this case '1', the second member in the array. Your BuildNewTree() function is not initializing the currentCaseVector array.
|
|
|
|
|
It is.
The function : resetCurrentCaseArray
do that work.(line 49)

Did you initialize the contents for this....
Two lines before this you write
T->currentCaseVector[i]='b';
in your code.

Yes I did intialized it.
I'm pointing from T to the array of pointers to Tic_Tac_Toe and thenthe object of Tic_Tac_Toe from the array. there is a currentCaseVector.
I intialized all.

So can anyone help me please?

I have already told you the answer. You are reading un-initialized data. Step through it with your debugger and keep your eye on the values.
|
|
|
|
|
Ok , Thank you , I will do that.

What do you mean? If you are talking about the sequence then WM_PAINT is called after the Window is created.

You can generate these messages using the SendMessage API if you are asking about specifically sending these messages to some window.

Did you see MSDN? From the MSDN
WM_CREATE
The WM_CREATE message is sent when an application requests that a window be created by calling the CreateWindowEx or CreateWindow function
WM_PAINT
The WM_PAINT message is sent when the system or another application makes a request to paint a portion of an application's window. The message is sent when the UpdateWindow or RedrawWindow function is called
You can insert these messages from property window to your application.

|

and also you dont need to declare this function(WM_PAINT) its in your dialog and you can use from it (dc) for draw&write to context_device

I am using the IWEbBrowser2 Control in my application and its working fine. but my application requires that the Browser control doesn't write to the Global IE History list nor should itread from the cache. Can anyone give me solutions? I am simply stuck. Googled for it but found no answers....
Any sort of help would be appreciated.
Thanks...

Ok. In VC++.Net 05, I've compiled a dll containing a namespace from one project in the solution. I'm now trying to use that namespace in another project but it is throwing up linking errors for the object it's compiled for the 2nd project. I have added the dll to the References in the Project Properties but nothing. If I say
> using namespace DllData
the compiler says that DllClass (in the dll) is not a member of DllNamespace. This makes sense as Intellisense is not picking up DllNamespace in the first place. I've tried including the headers for the dll source from the 1st project (which seems a bit counterproductive to me), which helps compiling the object code but then crashes the linker when it can't find the object code for the dll!
I know I'm doing something stupid or not doing something obvious. Please help!

I don't know if I understood you weel, but you always have to include header files in which your classes are declared. Without that, you will not be able to use the class.
Klempie wrote: then crashes the linker when it can't find the object code for the dll
Crash ?? You mean really crash or you get linker errors ? Did you link the project to the library associated with your dll ? If you are linking implicitely to the dll (so, not using LoadLibrary and GetProcAddress), you need to link to the library containing the information about your dll.
|

Thanks.
On the header note, I mean for example that there is no include statement for framework dll's if they are referenced in the project properties. For example, there is no include statement for System::Data. It's just there if System.Data is in the references. Surely the same should apply to user-compiled dlls?
What do you mean by "link[ing] the project to the library associated with you dll". Perhaps this is the problem. How would I do this in VS?

Errr... That looks like managed C++  . I am right ? If yes, you are in the wrong forum.

If it is in C++, when you create a dll, there is always a lib file that is created with it. In your project that uses the dll, you need to link to this library (it contains the link symbols necessary for your linker to 'load' the dll). But in managed, I don't know if it is working the same way.
