Check Windows Media Player

[pgrimpo]

I have my main page which calls the following OnShow:

--Check for Windows Media Version
ir_GetWMPVersion()
if (_WMPVer < "9.0.0") then
Page.Jump("MP9 Install");
end


Then it goes to the MP9 page because the version is low.

On MP9, when I install the program I do the following:

File.Run("AutoPlay\\Docs\\MPSetupXP.exe", "", "", SW_SHOWNORMAL, true);
Page.Jump("MainMenu");


So you can see, I install the program and when it's done, it jumps back to the MainMenu.

Now, on the main page, when I run that Check for Windows Media Version, shouldn't it check and see if the newly installed version is correct? Currently it just keeps looping and saying that I need to re-install.

Any help would be greatly appreciated!

What's the value of _WMPVer when the MainMenu page is shown the second time? (Use a Dialog.Message or Debug.Print action or something to check the value.)

You are correct. However, the dependency plugin that is used to detect WMP puts a function into the engine that you can call at any time and get "live" results:

ir_GetWMPVersion()

If you ever want to see what one of the built-in dependecy checkers are doing, just open the .dep file with WinZip (or similar program) and check out the .lua file inside. Dependency files are typically located in the C:\Program Files\AutoPlay Media Studio 5.0 Professional\Plugins\Detect folder.

Hope that helps (credit > Brett)

Yes, that thread was actually from my original post on this issue. However, when I call that function, it doesn't seem to be getting me the new results, unless I'm not calling the function correctly.

This is my code:

--Check for Windows Media Version
ir_GetWMPVersion()
if (_WMPVer < "9.0.0") then
Page.Jump("MP9 Install");
end


Shouldn't that check the version right there?

WMPVER = ir_GetWMPVersion();

if (WMPVER >= "9.0.0") then

else
Page.Jump("MP9 Install");
end

Note: When calling a Function, one must end such with the semi-colon.

Also, I did put this in to the Global Functions... section: (credit: Brett)

[CODE BEGINS]

function ir_GetWMPVersion()
local bOK = true;

--We're checking for Media player 7.0+ at this point . . .
bOK = Registry.DoesKeyExist(HKEY_CLASSES_ROOT,"CLSID\\{6 BF52A52-394A-11d3-B153-00C04F79FAA6}\\InprocServer32");

if (bOK) then
strFileName = Registry.GetValue(HKEY_CLASSES_ROOT,"CLSID\\{6BF52 A52-394A-11d3-B153-00C04F79FAA6}\\InprocServer32","NoName",true);
if (Application.GetLastError() ~= 0) then
bOK = false;
end
else
--version 7.0+ returned false, so we're now checking for version 6.4 . . .
bOK = Registry.DoesKeyExist(HKEY_CLASSES_ROOT,"CLSID\\{2 2D6F312-B0F6-11D0-94AB-0080C74C7E95}\\InprocServer32");

if (bOK) then
strFileName = Registry.GetValue(HKEY_CLASSES_ROOT,"CLSID\\{22D6F 312-B0F6-11D0-94AB-0080C74C7E95}\\InprocServer32","NoName",true);
if (Application.GetLastError() ~= 0) then
bOK = false;
end
end
end


--If a version was found, we now get the version information
if (bOK) then
verInfo = File.GetVersionInfo(strFileName);
if(Application.GetLastError() ~= 0)then
strVersion = "0.0.0.0";
else
-- OK, we have the file version
strVersion = verInfo.FileVersion;
end
end

--If there was no version found, bOK = false, and verison is set to "0.0.0.0"
if (bOK ~= true) then
strVersion = "0.0.0.0";
end

return strVersion;
end

Actually you don't have to use the semi-colon unles you want two statements on the same line, but it's very good practice to use it.

Just a tip, though: you can make your code maintain indentation in these forums by using the (code) (/code) tags. Note: replace the () with [].

Thank you Lorne for the correction on my Function (must end with semi-colon) comment.

And...

Thank you for the tip. I did not know 'code' was even the correct syntax. I was close and did not even know how close I really was. (grin)

Curious to see it in action:

Dialog.Message("Testing . . .", "This did work, super!");
