Hello in short and sweet
I am having a case like this:
Design is having Number of rows and Points per row
(This are editable)
Well user set the values for Number of rows say 4 and points per row 10 then system will make 40 objects and will store them the CObArray mentioned above.
Assigned with each object is an ObjectID say 0,1,2,....,39.
So above is the case when user mention all of the data provided and system stores them to CObArray
NOW if user changes the NUMBER OF ROWS or POINTS PER ROW or both. say 3 and 12 ,then system has to take it into consideration and has to restore the previous rowwise data back to the new one.
That is main theme and based on this only is my above query.

Hi, how to set form/control width and height in VC++ IDE or in code? I mean, if i want it
to be exactly 100x200pixels, how do i do that in the IDE or by code? Is there anything similar to Visual Basic?
I have a simple program that adds two numbers in array using MMX (inline assembly), the program works fine, the code as shown below,
The result on screen is :
70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93
which is correct,
however, if i change the line
char incamt[]={u,u,u,u,u,u,u,u};
to
char *incamt;
incamt=new char[8];
for(int j=0;j<8;j++) incamt[j]=u;
the program compiles but the result is wrong! Why is that?
Output:
9 82 117 68 17 18 19 20 17 90 125 76 25 26 27 28 25 98 -123 84 33 34 35 36
#include "stdafx.h"
#include <iostream.h>
void main()
{
const u = 5;
//an array of increment amounts to aid SIMD-style operation
char incamt[]={u, u, u, u, u, u, u, u};
//instr is an array of 24 bytes
char instr[]={65,66,67,68,69,70,71,72,73,74,75,
76,77,78,79,80,81,82,83,84,85,86,87,88};
//the following is an embedded assembly code which
//uses MMX instructions to add in parallel the
//amount u to all the bytes of the array instr
__asm
{
movq mm1,incamt //mm1 has value u in all its 8 bytes
mov cx, 3 //initialize loop count
mov esi, 0 //initialize index register
L: movq mm0, instr[esi] //mm0=next 8 bytes from instr
paddb mm0,mm1 //parallel add 8 bytes of mm0 & mm1
movq instr[esi],mm0 //move result to instr
add esi, 8 //update index register
loop L //loop back
emms //empty MMX state
} //end of assembly code
//C++ code to output the results for verification
for (int i=0;i<24;i++) cout<<int(instr[i])<<" ";
="" cout<<endl;
="" just="" to="" pause="" the="" screen
="" cin="">>i;
} //end of main

Use SetWindowPos for this purpose. Ex:
::SetWindowPos(hwnd, NULL, 0, 0, 100 <font color=green></font>, 200, <font color=green></font>, SWP_NOMOVE | SWP_NOZORDER);

Hello,
I'm building a graphic editor for a midi sequencer application. The problem I have is that when I add notes to the screen(by using bitmaps)and resize or in general cause the screen to be redrawn I lose all my added bitmaps. I tried using a double-buffer but I can't make it work with bitmaps since I cannot add bitmaps to the off-sreen bitmap. Is the only sollution to draw all notes using lines and ellipses and save them to the off-screen bitmap for outputting? I thought of using a bitmap array as a grid with all the possible notes but that doesn't seem right...Anyone that has a sollution to this problem would really help
I got 10 days left to hand in my project...
Thanks

hm.. I don't realy understand the problem, because your description is not very clear... but... you must collect the "view" of your data in some kind of array (tree or something like this) and in the Paint method you have to iterate the array (or tree) and bring the Items on the screen. when you add some "note" , you add it to the array and on the next repait it is shown on the screen.
DoubleBuffering is realy nice to avoid flickering.
you paint all the notes in the background and then flip it to the foreground.

I dont understand why Im getting this problem, because the code works fine in VC6, but when i use VC7, i get a whole range of errors, Im trying to connect to WMI, so I go through the usual steps, 1: CoInitializeSecurity, 2: CoCreateInstance, 3: ConnectServer, 4: CoSetProxyBlanket.
However when I build I get:
error C3861: 'CoInitializeSecurity': identifier not found, even with argument-dependent lookup.
&
error C3861: 'CoSetProxyBlanket': identifier not found, even with argument-dependent lookup
are both these functions using different libs or headers from the other two, Ive looked at the MSDN, and the FAQ, but I cant make sense of either.
Im also getting some wierd errors in my header file:
error C2143: syntax error : missing ';' before '*'
error C2501: 'WmiWrapper::IWbemServices' : missing storage-class or type specifiers
Im possitive there is no syntax error like missing ';' or anything like that.

Missing header?
VC7 using different set of headers if you are aware of it.

I got rid of the small weird errors in the header file but if anyone knows about header files that are used in VC7 that are not used in VC6, as regards WMI, then please let me know. The headers im using so far are:
#include string.h
#include wbemidl.h
#include windows.h
#include objbase.h
#include wbemcli.h
#include comdef.h
#include tchar.h
#include stdio.h
Some of these may even be sitting there doing nothing, According to the MSDN both functions that are giving me problems (CoInitializeSecurity & CoSetProxyBlanket) are in "objbase.h" and use "ole32.lib", and I have referenced both.

You should be using #include <windows.h> for any Windows features, including COM. It needs to appear before any other Windows-related includes. windows.h includes a whole load of other include files; you can speed up compiles quite a bit by using pre-compiled headers. It may be that you haven't copied your stdafx.h from your VC6 project.
objbase.h is included by ole2.h in the Platform SDK that ships with Visual Studio .NET 2003. However, ole2.h is not included if you define NOGDI unless you also define INC_OLE2.
The C2143 error often occurs if a type isn't declared; the compiler assumes you were trying to define a variable with that name instead. The '*' is then illegal at that position, so it assumes a missing semicolon.

Im already using #include <windows.h> and if I use precompiled headers then I get:
fatal error C1010: unexpected end of file while looking for precompiled header directive.
and the advice for this was "not to use precompiled headers" which gave me the problems I have now,
Also, What can I do to get rid of:
error LNK2001: unresolved external symbol _CLSID_WbemAdministrativeLocator
_CLSID_WbemAdministrativeLocator should be a default value in the function CoCreateInstance.
The code used looks like:
hRes = CoCreateInstance (CLSID_WbemAdministrativeLocator,
NULL , CLSCTX_INPROC_SERVER | CLSCTX_LOCAL_SERVER ,
IID_IUnknown ,
( void ** ) & IWbemLoc);
I have also tried:
hRes = CoCreateInstance(CLSID_WbemLocator, NULL,
CLSCTX_INPROC_SERVER,IID_IWbemLocator,
(LPVOID *)&m_pIWbemLocator);
and I get the same link error with both CLSID_WbemLocator & IID_IWbemLocator

OK, if you decide to use precompiled headers, you need to either #include your precompiled header file in each source file, use a #pragma hdrstop directive, or disable pre-compiled headers for that file (in which case you should include any headers that you need for that source file).
I can't see why CoCreateInstance would still be undefined if you've included both windows.h and objbase.h. Have you defined _OBJBASE_H_ somewhere?
You could try using the /showIncludes option to the compiler to show which files are actually being included. I'm not sure if this option was available in VS.NET 2002. If objbase.h is definitely being included, try using the /P option (with /C to preserve comments) to generate a pre-processed output and check whether the declarations are being output.
As for your other problem, you need to provide a definition as well as a declaration for your GUIDs. For WMI, you can simply link to wbemuuid.lib.

Adding wbemuuid.lib sorted it, thanks a million, your a star!

Hello,
I wrote applications that suppose to open automatically by the auto
play mechanism of the WinXP, I entered the correct values to the
registry and the application start ok.
The problem I have is that I get a message box with error every time:
'E:\ The device is not ready'
Any ideas what is the problem?
The Registry settings:
--------------------------------------------------------------------
[HKEY_CLASSES_ROOT\MyApplication]

[HKEY_CLASSES_ROOT\MyApplication\shell]
[HKEY_CLASSES_ROOT\MyApplication\shell\open]
[HKEY_CLASSES_ROOT\MyApplication\shell\open\command]

Hi,
I am sorry, I do not have the answer to your question but another one with which you can help, I guess.
I just entered all the correct values into the registry, but my application does NOT start. Is there anything I have to do from within the application?
I verified my entries by starting another application, which works fine. But my own does not start at all. Any ideas?
Thanks,
Sathie

Handle WM_SIZING. You can restrict the user's operation to allow sizing by a specific edge or corner only.

To get them to talk you have to change the firewall on the server side to forward a port to the server machine-- how you do this depends on your firewall.

Why this error comes?. is there any remedy for this?. can my application get relief from it, if i download VC6 service pack?.

You need to install the unicode version of your MFC lib which by default not set in your stardard installation.
