Hi,
I'm integrating some some WPF controls into a MFC dialog box.
One of the control is a media player that shows live video.
The second one is a label that shows the current video time.
What I need is to have is the label on top of the media player. The label should only display the time, so its background needs to be transparent.
Right now, I have the video player running fine inside the dialog box, but I am unable to have the time displayed as I wish. It just overlap the video player.
Both WPF components were creating by following instructions from this link.
https://msdn.microsoft.com/en-us/library/ms742522(v=vs.110).aspx#hosting_a_wpf_page[^]
I try to set the label with a transparent background.
timeLabel->Background = gcnew System::Windows::Media::SolidColorBrush (System::Windows::Media::Colors::Transparent);
But the label background is shown black.
I also try to set the Transparent flag of the MFC CDialog to true, but it didn't have any effect.
How can I that fixed?
Do I need to set up something special when I instantiate the WPF controls?
Do I need to call some functions from inside the MFC dialog box?
Thanks,
Alain Migeon

This looks like Managed code. Might try the other forum.

Thanks for suggestion.
I have just done so. But I'm not sure that the answer to my problem is inside the WPF part.
It can also be in the MFC one.

Hi,
I want to download file from a given URL. I am using URLDownloadToFile() function for this purpose, but I am not getting the actual file. When I try to run the file, it throws an error.
As an example, If I download MSVS 2010 service pack 1 from Microsoft's website, the file size will be 795KB. But if I download using URLDownloadToFile() function passing the url and file name, downloaded file size will be 99 KB.
Is there any method to download an exe from a URL in C++.
Any help wll be appreciated.
Regards,
mbatra

Which URL?
You must pass the complete URL to the file. When browsing MS for downloads, they are often provided by a confirmation page that will start the download. If you pass that URL, wou will download the web page content. On such pages you will usually find a link to the real file if the download does not start after some time.

Hi Jochen,
Thanks for your response. I got the code working. I was passing the link of the confirmation page, that was the issue.
Thanks..!!

Hi Guys!,
I've been trying to make a simple tracking game but I'm having trouble just setting up the basic game states. I'm hoping to use a finite state machine(FSM) to switch between screens but every article iv read about them is different and sometimes they leave out details, I couldn't understand it properly.
For example if I've two screens , Menu and Game screen. And in game I've to implement states for a simple tracking game. What would be a FSM look like to switch between them.??

They are different because FSM are widely used, for different purposes.
There are not may details to understand. A finite state machine is a rather simple stuff. You should understand your scenarion, though.
By wild guess, you could do something like (or go with a more OO approach)
struct FSMData
{
FSMState state;
};
void update_fsm(FSMData & fsmd)
{
switch(fsmd.state)
{
case STATE_MENU:
handle_menu(fsmd);
break;
case STATE_GAME:
handle_game(fsmd);
}
void handle_menu(FSMData & fsmd)
{
if ( userSelection() == PLAY_GAME)
{
fsmd.state = STATE_GAME;
return;
}
}
void handle_game(FSMData & fsmd)
{
if (userInput() == QUIT_GAME)
{
fsmd.state = STATE_MENU;
return;
}
}

CPallini has given you a basic example for a FSM - you will understand that we're not here to provide ready solutions. You have formulated your game states - what stops you from extending that sample with that, or, at least trying?

Hi
I am getting a number of errors in MFC functions (Using Visual Studio 2012)
can't convert const char [xx] to LPCTSTR when using a literal with " double qoute it
was my understanding that anything with " was a pointer now weather its char * or
LPCTSTR is a different issue however it shouldn't be of type const char[xx]
Thanks

Do you have the project set to use the Unicode character set? If so LPCTSTR is equivalent to LPCWSTR, so you cannot convert a char pointer to it.

you did it again !!!!!

Thanks. Sadly my flashes of brilliant intuition are getting fewer and further apart these days.

Try using TCHAR instead of char, and wrapping string literals in the _T() macro.

I prefixed the string with a _T macro
And it compiled
Thanks for your help
I have to re-read and he article

In my visual Studio project for character set I choose <not set=""> not sure what that means ansi?
1 byte
The other two choices were Unicode and multi byte
So if Unicode is character representation by 2 bytes. what is multi byte ?

So if I select for my project setting char set -> not set .... And wrap all of my strings with a _T( macro is that best practice
... Thanks

Will you show me the full example?
