And when you get the address of the proc in the DLL, I assume you call it? Are you trying to do some kind of plug and play system where you can have a different window depending on which DLL you load? Why not just have a call into the DLL to create the dialog and then return?
You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

Oh, I should've said this in my first post - I'm injecting this dll into selected processes, so the event that has to trigger a dialog box in my app could or could not happen and I don't know when it will happen.
Hope that helps?

Hi,
i am using ShellExecute to launch a url in the default browser, the same code has been working for a few years now.
all of a sudden one guy is complaining that URLs are not working on his 3 PCs
what happens is ShellExecute is called and "If IE8 is running it opens up the site fine but if no IE8 instance is running a new instance comes up, tries to load the page and just keeps loading and nothing happens"
this is very weird cause its tha same old boilerplate code for ShellExecute
Here is the code
HINSTANCE ret = ShellExecute(NULL, "open", "http://www.google.com", NULL, NULL, SW_SHOWNORMAL);
any ideas are more welcome
thanks for your time

I think your call to ShellExecute has a problem. The third parameter should be the name of the .exe, and the fourth should be the command line parameter; in this case, the URL. What happens if you try this? (It works for me) -
ShellExecute(NULL, _T("open"), _T("iexplore.exe"), _T("http://www.google.com"), NULL, SW_SHOWNORMAL);

That is not what I would expect. Your code is enforcing Internet Explorer as the browser to open a particular URL; putting the URL (or any filename with a file extension association) as the third parameter should call the associated EXE to open that URL/file, similar to a double-click inside Windows Explorer. I suggest you try with a .doc file.

Hadn't thought of that... MS slave that I am. I was thinking IE, not generic browser.

Is there an existing C++ class/function which can translates IP info (such as 123.234.567.333) to country string (or country and state string)?
|

Try searching for geolocation database, one example is ip-countryside[^]. Some IP ranges are clearly assigned to a location, for others there is manual labour involved to map them, that's why you would need a database. Adding new functionality to your network application, includeh10?

Hi, guys,
I am using ncurses library on *nix.
I have a while loop that always keep running until a user hits a button that would exit the loop, also it accepts other buttons and in respect to their code, certain actions take place. i have several issues i'd like to fix. first of all, how can i solve this:
[code]
while(cond1)
{
halfdelay(2);
chr = getch();
switch(chr)
{
//code
}
foo(chr);
}
[/code]
if key x was pressed, something would happen, then it would do a certain action, if nothing was pressed, it would continue doing that action in respect to they previous char (in this case, char x). if key(char) x was hit again, it should ignore it (without significant pause) and continue doing foo() in respect to key x.
my problem is that pause.
problem 2: since i have that pause, if a user woudl decide to do a silly action and hold key x for long time (not a single quick key hit, but hoding it), obviously the action would be paused for that moment. how can i eliminate that problem?
any hints, please?
thanks

I want to begin to learn how to do visual gui programs in VC++. I am good with c/c++. To get myself starting I would like to write an app that simply receives messsages over a tcp connection and displays them to a scrolling window. The window should automatically scroll down as new messages are added. But the user should have the ability to scroll back as well.
Any suggestions on how to approach this? Also, as a follow on project I'll want to display data in row/column format and be able to update cells as changes are received over a tcp connection.
Thanks

Do you know how to do the "receive tcp message" stuff (code and implementation) ?
if you know how to do that, then the rest is quite simple.
Create a worker thread that will receive the data; when the data is received, send a message to the main UI thread (
Create a simple UI thread (main UI, do not create and manage UI in the worker thread)that contains either a CListBox or a CListCtrl. implement handlers for the messages sent by the worker thread.
good luck.

Watched code never compiles.

Thanks. Anything I need to be careful to select or not to select when I create the project in VC? When you say implement handlers, do you mean each message gets it own handle and is processed from that perspective?

I would suggest you forget about the TCP stuff until you have mastered the text viewer and scrolling. Whether you use simple Win32 or MFC this can be quite a challenge and TCP would only complicate matters. Start with a view window and add the scroll features then add a mechanism to send some lines of text, say up to 100 and see that your scrolling is working. Then when you have all those features under control you can start to add the more complex pieces of the TCP feed.
It's time for a new signature.

Hi Alan! I suggest an alternative approach without multi threading to get up and running quickly:
1) create a new MFC project and add a CListBox control: Using the CListBox control[^], this comes with a working example dialog project.
2) Add a TCP client socket such as CAsyncSocket to your dialog: Socket Programming with MFC (Part 1)[^], this will also explain which initialisation is needed in your application.
3) Add a button to your dialog so you can connect/disconnect to a server.
The client will tell you in its OnReceive()[^] handler when more data is available, you can add this to the listbox with AddString()[^] and scroll listbox with SendMessage(WM_VSCROLL, SB_BOTTOM, NULL). There are many ways to communicate between socket and GUI, for starters you could give the socket object a pointer to your dialog. For example with a method OnReceiveText() that you call from your socket whenever a full text line is available:
void CMyDlg::OnReceiveText(const char* szText)
{
m_listbox.AddString(szText);
m_output.SendMessage(WM_VSCROLL, SB_BOTTOM, NULL);
while(m_output.GetCount() > 10000) m_output.DeleteString(0);
}
Hope this helps

I think you have difficulty understanding the purpose of these forums. They are here to help with technical questions, not so someone can provide you with a working solution to order. Reread the guidelines on how to ask a question.
