Hello,
I have recently created a ticker tape which is used to display strings. It is a common single line ticker. The program currently reads in a file from which it takes in the dimensions, colors, speed, and position of the ticker as well as the string that it should display and the spacing between repetitions of the string.
I would like to write a new ticker however, which also reads the information from a file (preferably an xml file) which scrolls multiple lines at the same time, and which can also scroll images of approximate dimension: 140 X 110 pixels.
For example, it could look something like:
|----140px-------|
__ _______________________________________________________________
| | line1 line1 | |
| | line2 line2 line2 | |
110px | line3 line3 | IMAGE |
| | line4 line4 line4 | |
| | line5 line5 | |
_ |_____line6 line6 line6________________|________________|________
for a file that looked something like:
<ticker>
... <- indicates ticker properties
<item>
<text>line1 line1</text>
<text>line2 line2 line2</text>
<text>line3 line3</text>
<text>line4 line4 line4</text>
<text>line5 line5</text>
<text>line6 line6 line6</text>
</item>
<item>
<image>IMAGE</image>
</item>
</ticker>
where the number of 'text' tags nested in an 'item' tag is fixed (to some number, not necessarily 6) and there is only one 'image' tag per 'item' tag.
Also, another tag which specifies the spacing (pixels or time) between items should be specified in the ticker properties.
The problem is that since I am relatively new to the VS C++ (using .NET 2003), I don't really know how I would go about doing this.
If anyone has done a similar project, or could possibly guide me or help me with the code, it would be greatly appreciated.
Thanks in advance,

Any particular thing? It should be a matter of adjusting what you are already doing, no? Maybe if you post some code of what you are doing now with the single line ticker (just the portion where you have doubts, of course), it might be easier to guide you.

Hello Jose,
First of all, thanks for the reply.
I forgot to mention in the original post that the code for the single-line, text-only ticker is written in VB and that I would very much prefer if the code for the new multi-line, text and image ticker was written in c++. This means that I can probably and would rather not reuse the old code.
As far as if there is anything in particular, sort of. Before, I was using a static label and scrolling it. However, with multiple lines, should I use a read-only multi-line text area or several static labels? And also, since I may have several "messages" (items with nested text), I would need several text areas, or image controls for the images. How do I make all of these areas scroll unanimously? Can I embbed them in another layer and make that layer scroll?
I hope my response was not too confusing.
Thanks a lot,
-----------------
Genaro

I want to create a dialog that is a child of another dialog. This child dialog would have a title bar so I can move it around, but as a child it would be confined (cliped) within it's parent dialog.
I already tried the obvious way. Create a dialog, set type as Child, then create an object for this dialog and call the create method.
ex:
void CParentDialog::CreateChildDialog()
{
m_ChildDialog.Create( IDD_CHILD, this );
}
What happens is that the dialog is there, but it is being drawn over by other controls in the parent dialog, and also I cannot click on it to activate it or move it around.
Louis.

ok, i figured out all the settings to achieve what I want...
Basically, what was important, is that I had to set the WS_CLIPSIBLINGS window style to all child of the parent dialog.
case closed.

When the messagebox "Server busy" pops up from an autmation server what exactly does that mean? Busy in that it's processing something, busy in that it is in my event sink waiting to return or something else that I'm not aware of?
Thanks

I think it means "busy in that it's processing something". It may appear with slow loading servers (MSWord for instance). It may also appear if the server has activated a modal dialog, and of course if the server is executing a long operation.
With MFC, it seems like there are some ways to control how / when / if these dialogs appear, although I've never used them so I'm not entirely sure. Take a look at AfxGetOleMessageFilter[^] and the COleMessageFilter Class[^].
If you aren't using MFC, take a look at CoRegisterMessageFilter[^] and IMessageFilter[^]. You would need to create a class that implements IMessageFilter, but that's exactly what MFC's COleMessageFilter does and its source may serve as a guide on how to do it.

Is it possible to load a dll in an ActiveX control? I have tried implicitly and explicitly loading the dll and I have problems either way. When implicitly loading, the container project fails when loading the control saying...
CoCreateInstance of OLE control {8601721E-DF2A-4DA8-816D-ACB2FEB9E287} failed.
>>> Result code: 0x80040154
>>> Is the control is properly registered?
The control is properly registered though. When I try to load the dll explicitly, the LoadLibrary call always returns NULL and the GetLastError says it can't find the library. The dll is in the correct location. Is this all because you can't load a dll from an ActiveX control, or am I missing something. Thank you in advance.

As far as I know, being an ActiveX control or not shouldn't make a difference when loading other dlls...

I've seen reports of this error appearing after upgrading to XP with SP2. ISTM some mention to msxml.dll too...
Have you tried loading the dll from another dll/exe (not the ActiveX)? Have you tried running the Depends utility?

When I execute the following code in my program, it works fine when I toggle the buttons that I generated. However, if I go into IE and manually set the proxy via Tools -> Internet Options -> Connections -> Lan Settings -> Check/Uncheck "Use a Proxy setting...", it works the first time and runs the correct method, so if I check the box and turn the proxy server on and click Ok it will run the ProxyOn() method. However if I don't compeletly close out Internet Options and and go back into Lan Settings and uncheck the box and click OK, it will run the ProxyOn() method again. Now the really confusing part is the fact that if I do it a third time or more, it won't double run the methods but it will be one off from what it should be running. I know its alot to digest but does anybody have any ideas. So here I have the thread that I create to watch for a change in the proxy setting.
hThread = CreateThread (NULL, 0, (unsigned long (__stdcall *)(void *))this->ThreadFunc, (void *)(this), 0, &this->hThreadId);
DWORD WINAPI CMFToolbar::ThreadFunc(LPVOID lParam)
{
CMFToolbar *toolbar = (CMFToolbar*)lParam;
while(1){toolbar ->WINAPI_tWinMain();};
}
int CMFToolbar::WINAPI_tWinMain()
{
LONG l = 0L;
HKEY hKey = {0};
//Open Registry Key to watch
l = RegOpenKeyEx (
HKEY_CURRENT_USER,
_T("Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings"),
0,
KEY_NOTIFY,
&hKey );
if(l == ERROR_SUCCESS)
{
// The following call will wait until a change is made to the registry key.
l = RegNotifyChangeKeyValue (
hKey,
FALSE,
REG_NOTIFY_CHANGE_LAST_SET,
NULL,
FALSE );
RegCloseKey(hKey);
//Determines whether or not Proxy is enabled and executes proper method
DWORD flag = 0;
if ( InternetGetConnectedState ( &flag, 0 ) )
{
if ( flag & INTERNET_CONNECTION_PROXY )
{
fout<<"Proxy Off Method"<

Have you tried reading the "ProxyEnabled" (I guess that's the one) value in the key you are monitoring instead of using InternetGetConnectedState?

I was also wondering why the code I posted before was acting that way. I'm just assuming I'm not seeing the problem because I put it together.

Well, I couldn't find anything obviously wrong in your code either, but that doesn't mean a lot, since I have no experience with that kind of things. The only thing I noted is that there is a possibility that if a change is made between your call to InternetGetConnectedState and the call to RegNotifyChangeKeyValue in the next iteration, you would lose a notification. However, that's a very tiny fraction of time, and it doesn't seem possible to be caught in that situation doing changes through IE's dialogs. Furthermore, it wouldn't explain what you describe (InternetGetConnectedState returning out-of-date results)...
I think the actual problem may be related to InternetGetConnectedState not taking its results directly from the registry. If the state is also stored in some other place, maybe your query is being done after the registry was modified but before this other state is actually updated. That's why I suggested reading the registry; reading the values from the same place about which you get notifications seem to make more sense. Does it work?

Well I'm having some trouble checking the registry key setting for "ProxyEnable", I can't seem to get it to work. I'm also not to sure about getting a DWORD value from the registry, but I'll let you know if I figure it out.

I want to detect when a user closes a window by clicking on the X in the title bar. I dont know how to create a message map to catch the event. When I close the Window, I want to delete the CWnd object associated with that Window.
Thanks.

Handle the WM_CLOSE message (CWnd::OnClose()).

If you are doing this from the window that is being closed, then the proper place to do it is in the PostNcDestroy() function
void CMyWindow::PostNcDestroy()
{
delete this;
}

Hi
Anyone knows that there is such tranlation tool exists or not. This translation tool can read a exe file's resource text and write back the translted text to the exe file.
Thanks,

Resource translation is big business - I doubt you'll find a robust mechanical solution. That being said, check out the translator example in this[^] article.

Which implies that you have started it but have run into a snag. What exactly is troubling you? The more specific you are, the more help you'll potentially receive.
