I fixed this problem using another method.

I know there is a Api can get icon from other application conveniently, but i forget which is it. Or is there any other methods can get icon from other application.
I need to load it and display it in my app.

you need ICON as Image or Handle Only.. If Handle ExtractIcon[Ex] will work, if you want Image then you have to use combination of UpdateResource, BeginUpdateResource and <mshelp:link tabindex="0" keywords="_win32_EndUpdateResource_cpp" xmlns:mshelp="http://msdn.microsoft.com/mshelp">EndUpdateResource

 Hi,
I am using Visual C++ 6.0 MFC on a Windows 2000 box. I want to be able to automate the creation of charts from my C++ application. I can create a chart of x-axis vs y-axis for a single series of data but I can't figure out how to do anything more powerful. My data is output to the spreadsheet as follows... cell A2 is the what should be the series name (device 1) cell B1 is the column header (Line Voltage) and cell C1 is the column header (Current). The current is measured for increasing line voltages and charted. My problems are twofold. How do I get the series name (device 1) to show up in the legend instead of 'series 1'? How do I get multiple series on a single chart? For example, if 5 different devices were tested the 'Line Voltage' (category / x-axis) would be the same for each device but the measured currents would differ. The cells for the 10 measured currents for 'device 1' would be C2 through C11. The cells for the 10 measured currents for 'device 2' would be C15 through C24. The cells for the 10 measured currents for 'device 3' would be C28 through C37 and so on. I have been all over the internet but have only found an example of how to create the simplest of charts. Any link to decent documentation on how to do this would be appreciated.
Thanks

Since I usually get a quick response and have not heard anything in 24 hours I'm going to assume that this can't be done.

I am looking for help to display 12 waveforms in one graph. The waveform will have the same horizontal time axias, stacked up as 12 different channels. Such as:
Any code, functions to do this ?
Thanks for any help.

Hi all,
I am interested on importing contacts from my msn messenger.
i know how to use the IMessenger2 interface and to loop over the get_MyContacts()....
the problem is that IMessenger2 is the windows messenger (msmgs.exe) and not the msn messenger (msnmsgr.exe).....so on windows 2003 server (which doesn't come by default with windows messenger), importing contacts doesn't work...
can any1 suggest how i can connect to the msn messenger and not to the windows messenger?
any exposed interface?
thanks in advanced

Around a year back i have created a program using automation of MSN Messenger, in My scenario if the MSN Messenger is installed on my computer IMesenger2 work for MSN otherwise good old WindowMessnger, but here situation seems to vice versa

How can I get GDI+ stuff to compile in VS 2005?
I started new WIN32 application project with wizard and only added #include <gdiplus.h> and started build. I get a lot of errors. Probably has todo with the " Breaking Changes in the Visual C++ 2005 Compiler " .
I tried to switch of warnings and lot of other things I forgot.
Is there a simple way to get it going?

Here's an example i took,
#define UNICODE<br />
#include <windows.h><br />
#include <gdiplus.h><br />
using namespace Gdiplus;<br />
<br />

Yeah, I found a similar example too.
But it won't compile.
So I only put in the "include <gdiplus.h>" line and comiled my "test.cpp" (based on win32 template), at least it should compile (apart from being usefull or not, in the end). And no, it won't compile with my version of VS 2005.
The first errors I get:
Error 1 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int e:\program files\microsoft visual studio 8\vc\platformsdk\include\gdiplusimaging.h 67
Error 2 error C2440: 'initializing' : cannot convert from 'const char [37]' to 'int' e:\program files\microsoft visual studio 8\vc\platformsdk\include\gdiplusimaging.h 67
Error 3 error C2146: syntax error : missing ';' before identifier 'IImageBytes' e:\program files\microsoft visual studio 8\vc\platformsdk\include\gdiplusimaging.h 67
Error 4 error C2470: 'IImageBytes' : looks like a function definition, but there is no parameter list; skipping apparent body e:\program files\microsoft visual studio 8\vc\platformsdk\include\gdiplusimaging.h 67

Can someone please answer the below questions?
Thanks in advance!:
=====
1. How do you ensure data consistency with mulitple threads.
2. How do you implement a single linked with multiple threads accessing and updating the same. What are the different ways to do it. What is best for performance?
3. Write code for inserting into singly linked list, taking into consideration that multiple threads can call the same function concurrently.
=======
1. Implement Singleton design pattern.
2. Update the above code keeping in mind the multiple threads can use this class.
3. And change the solution such a way that we get best performance.
4. Discuss algorithm and write code for reversing the words in a string.
5. Come up with an algorithm for the above problem such a way that we don't use extra space.
============
1. If there is a string with only characters 'a' & 'b' in it and given a decode pattern as below
aaa - 1
aba - 2
bbb - 3
Create a new string from the input string and above pattern in which all the instances of pattern above would be replaced with the appropriate decode value in the new string. For example, if the input string is aaaababbbaa the output would be 123aa.
2. Networking questions. Difference between TCP, UDP and why should one use UDP.
3. What is multicast.
4. How does data send and receive work in UDP. How much data can application send at one shot with UDP and how does it work with TCP?

No ... I found these questions somewhere on the web!

These are all very basic questions that anyone who has taken a course or multi-threaded applications and data structures/algorithms would be able to answer without too much of a problem. Since it is unclear whether you are applying for the job yourself, I don't think anyone here will answer them for you (at least not 100%).
If you are truly looking for academic purposes, use Google. You won't have trouble finding the answers to any of those questions (although, you won't find them all in 1 place).

Anyone know how to get a status bar that sits on the lower protion of a dialog based app. And once it is created, how would you update it?
|
|
|
|
|
Have you looked at making an SDI app with a CFormView (Dialog). You get the Statusbar for free.
To update a status bar you can handle the OnCmdUpdate message
|
|
|
|
|
You have to create and attach it to the dialog yourself (basically, what MFC does free for you with Window'd apps -- that is SDI/MDI -- you have to do manually).
Your dialog class will declare a CStatusBar member variable and you will need to initialize it at some point (OnInitDialog is a good place) and set how many panes you want, their sizes, styles, etc. After that, you update the text/data in the panes the same way you would normally.

Hi, everyone,
I use TrackPopupMenu() in my CMyView::OnContextMenu() to display a popup menu. But I found that code won't come out TrackPopupMenu(), unless popup menu disappeared. that mean CMyView won't handle any other message except mouse click( which makes popup menu disappeared ).
This is not acceptable, in "real-time" data processing.
Anybody have any idea?

What exactly are you trying to do? Perhaps someone can offer some alternatives with more information ...

Soory.
I don't want my application blocked, when waiting for user is thinking which item in the popup menu to select.
because TrackPopupMenu() blocked the message coming in.
