Is it possible to use MFC in an Add-In for Visual Studio .NET 2003 after one has chosen C++/ATL as the language to write the Add-In in? I have tried using MFC but I always get an error about have the Main function being defined twice.
Does anybody know of a solution?
I am the handsome one in the crowd.

As much as I love C++ it just isn't the right language to try to write add-ins with. Use C# or some other .NET language with managed C++ extensions if you have to.
During my first experiment with add-ins I learnt enough C# to be able to build a fairly reasonable build logger, with a lot less code than an equivalent C++ project, mainly because of all the interfaces that have to be implemented.

Hello,
You should try this[^] article. It should fit your needs.
Besides that, try googling first next time...

Hello,
I think that you want something like an add-in. I don't know how to help you on the add-in part, but I know that you can do almost anything you want from there...
Good luck!

What you are after is IE Automation. I have dozens of little VBS files on my computer that do various things with Web sites. Some I have even added as a scheduled task if I want to do them regularly. For example, here is one that gets the current security threat level. It's not finished (I was just testing az theory), nor is it as "pretty" as the XML version that is floating around.
Dim objIE
Set objIE = WScript.CreateObject("InternetExplorer.Application")
objIE.Navigate "http://www.whitehouse.gov/homeland/"
objIE.Visible = true
While objIE.Busy = true
Wend
Dim objTables
Set objTables = objIE.Document.all.tags("TABLE")
Dim objTable
Set objTable = objTables(12) ' get the 13th <TABLE> tag
Dim objRow
Set objRow = objTable.rows(0) ' get the 1st <TR> tag
Dim objCol
Set objCol = objRow.cells(0) ' get the 1st <TD> tag
Dim objImg
Set objImg = objCol.all(0) ' get the 1st <IMG> tag
MsgBox objImg.srcHere's one I made for a friend a few years back to help him enter a sweepstakes contest:
Dim IE
Set IE = CreateObject("InternetExplorer.Application")
IE.Visible = True
IE.Navigate "http://www.nralive.com/sweeps/enter.cfm", NULL, NULL, NULL, NULL
' wait until the page is fully loaded
While IE.Busy = true
Wend
' assuming there are 4 radio buttons named "enteringBy", operate on the 4th (index 3) one
IE.Document.all("enteringBy", 3).checked = true
IE.Document.all.fname.Value = "J"
IE.Document.all.lname.Value = "S"
IE.Document.all.email.Value = "j"
IE.Document.all.address.Value = "2"
IE.Document.all.city.Value = "S"
IE.Document.all.state.Value = "O"
IE.Document.all.zip.Value = "7"
IE.Document.all.phone.Value = "4"
' click the "next" button
IE.Document.all.tags("INPUT").item(12).click()

Hi all
I derived a class from CSocket.

I get error number 10022 when I call m_Socket.Create(8998,SOCK_DGRAM,NULL).
It works well on win2000, but fails on winNT dont know why ?
Any help would be greatly appreciated!

Hello,
I am trying to send a structure using PostMessage.
My structure is of the form:
typedef DATA
{
int EventID;
CString ModuleName;
CString ThreatName;
} info;
info info_data;
PostMessage(WM_MYMSG, (info_data&)wParam,NULL);
In the recieving thread I tried this way:
info_data = (info_data&)wParam; // I am getting runtime error here.
Can anyone please help me to pass a user defined structure using PotMessage?
Thanks
Madhavi

Use wParam to send your structure pointer, i.e.
PostMessage(WM_MYMSG, (WPARAM)&info_data, NULL);
Note that you can only send pointer to your structure, so make sure that it is accessible in message handler.

Hi,
Thanks for the inputs.
When i tried this way,
AfxGetMainWnd( )->PostMessage(WM_LOGMSG, 0, (LPVOID)&info_data) ;
I got this error :
error C2664: 'CWnd::PostMessageA' : cannot convert parameter 3 from 'LPVOID' to 'LPARAM'
Can you please let me know how to proceed?
Thanks
Madhavi.

Sorry for mistake. Use:
AfxGetMainWnd( )->PostMessage(WM_LOGMSG, (WPARAM)&info_data, NULL);
and in your message handler, type cast wParam to info_data pointer, i.e.
info *info_data = (info*)wParam

Hi,
<br />
typedef DATA<br />
{<br />
int EventID;<br />
CString ModuleName;<br />
CString ThreatName;<br />
} info;<br />
<br />
info* pinfo_data = (info*)GlobalAlloc(GPTR, sizeof(info));<br />
AfxGetMainWnd( )->PostMessage(WM_LOGMSG, 0, (LPARAM)pinfo_data);
convert to LPARAM, not to LPVOID 
allocate structure with API calls, and
free structure in target thread, not in main thread

Dont forget also that when using PostMessage() you cannot pass pointers to objects on the stack as they may go out of scope before your message gets processed. If you need it to be done whiel its in scope, use SendMessage()
If you vote me down, my score will only get lower

Hello,
I am writing an application which uses two threads.
I have a list<int> variable in my Document class.
THREAD 1
In this thread, I am filling a list from back i.e pDoc->list.insert(list.begin(),data);
THREAD 2
In this thread, I am extracting each element from top of the list, and displaying it on the UserInterface i.e
data = pDoc->list.pop_front();
Display(data);
THREAD1 cotinously reads and adds data at the bottom of the list while THREAD 2 gets data from the top of the list and displays it.
Can I directly access the list memeber available in my document class as above in the two threads.
When I tried the above, it worked fine when the list had limited number say 10 to 30 records, but as the size of list was growing to say 10,000 records the program was crashing.
Can anyone please help me to solve this ?
Thanks
Madhavi

Your problem is that, you are using a shared resource (list) between two threads. You need synchronization between threads, so that only one thread at at time can access shared list. To achieve this, you can use CEvent, CMutex, or CSemaphore, depending on your needs and choice. See any good reference on these classes.

You can also try to use thread-save lists. I think there are some at www.stlport.org.

Hi,
I have an application in VC++ 6.0 and Hierarchial database files for working. Plz Note, Here I am not connecting my application to any database, insteed I am using the Hierarchial database files for my application.
1. First I start my application and open the database file using open menu which intern generates the XML files from database files. On "save" the data is saved in "Workspace"
Next time when I start the application it loads the last recently saved workspace.
2. Now I starts one more instance of same application i.e. second instance of same application. Here it loads the last saved workspace (same workspace is opened in first instance ). So working on same workspace in two different instaces is dangerous for data.
I want to restrict the second instance from loading the workspace if it is already loaded in previous instance.
Also, I should be able to work on different workspaces in different application instances.
Q: How to manage this?
Plz send any samples, codes, ideas to me
Thanx for your valuable help and support.
Thanks & Regards,
Neeraj

Are you saving 'Workspace' as file? If yes, then while opening workspace file, open it in exclusive mode, so that access is denied to second instance of your application. For example if you are usinf CFile to open workspace use:
CFile file;
file.Open("workspace", CFile::shareExclusive|CFile::modeReadWrite);
